Full textAbstract:
As part of an effort to develop an intelligent tutoring system, a set of knowledge representation
frameworks was proposed to represent expert domain knowledge. A general representation of time points and temporal relations was developed to facilitate temporal concept deductions as well as facilitating explanation capabilities vital in an intelligent advisor system. Conventional representations of time use a single-referenced timeline and assigns a single unique value to the time of occurrence of an event. They fail to capture the notion of events, such as changes in signal states in microcomputer systems, which do not occur at precise points in time, but rather over a range of time with some probability distribution. Time is, fundamentally, a relative quantity. In conventional representations,
this relative relation is implicitly defined with a fixed reference, "time-zero", on the timeline. This definition is insufficient if an explanation of the temporal relations is to be constructed. The proposed representation of time solves these two problems by representing a time point as a time-range and making the reference point explicit.
An architecture of the system was also proposed to provide a means of integrating various modules as the system evolves, as well as a modular development approach. A production rule EXPERT based on the rule framework used in the Graphic Interactive LISP tutor (GIL) [44, 45], an intelligent tutor for LISP programming, was implemented to demonstrate the inference process using this time point representation. The EXPERT is goal-driven and is intended to be an integral part of a complete intelligent tutoring system.Applied Science, Faculty of

Full textAbstract:
Information system (IS) support of human problem solving during the complex task of auditing within a computer environment was investigated. 74 computer audit specialist professionals from nine firms participated in the field experiment. Task accomplishment behavior was recorded via a computerized activity-logging technique. Theoretical constructs of interest included: 1) IS problem-solving support, 2) task domain knowledge, and 3) decision-making behavior. It was theorized that task domain knowledge influences the type of IS most functionally appropriate for usage by that individual. IS task presentation served as the treatment variable. Task domain knowledge was investigated as a moderating factor of task accomplishment Task accomplishment, the dependent variable, was defined as search control strategy and quality of task performance. A subject's task domain knowledge was assessed over seven theoretical domains. Subjects were assigned to higher or lower task domain knowledge groups based on performance on professional competency examination questions. Research hypothesis one investigated the effects of task domain knowledge on task accomplishment behavior. Several task domain knowledge bases were found to influence both search control strategy and task performance. Task presentation ordering effects, hypothesis two, were not found to significantly influence search control strategy or task performance. The third hypothesis investigated interaction effects of a subject's task domain knowledge and task presentation ordering treatments on task accomplishment behavior. An interaction effect was found to influence the subject's search control strategy. The computer-specific knowledge base and task presentation ordering treatments were found to interact as joint moderators of search control strategy. Task performance was not found to be significantly influenced by interaction effects. Users' task accomplishment was modeled based upon problem-solving behavior. A subject's level of task domain knowledge was found to serve as a moderating factor of IS usage. Human information-processing strategies, IS usage, and task domain knowledge were integrated into a comprehensive IS user task model. This integrated model provides a robust characterization scheme for IS problem-solving support in a complex task environment.

Full textAbstract:
Distribution and parallelism are historically important approaches for the implementation of artificial intelligence systems. Research in distributed problem solving considers the approach of solving a particular problem by sharing the problem across a number of cooperatively acting processing agents. Communicating problem solvers can cooperate by exchanging partial solutions to converge on global results. The purpose of this research programme is to make a contribution to the field of Artificial Intelligence by developing a knowledge representation language. The project has attempted to create a computational model using an underlying theory of cognition to address the problem of finding clusters of relevant problem solving agents to provide appropriate partial solutions, which when put together provide the overall solution for a given complex problem. To prove the validity of this approach to problem solving, a model of a distributed production system has been created. A model of a supporting parallel architecture for the proposed distributed production problem solving system (DPSS) is described, along with the mechanism for inference processing. The architecture should offer sufficient computing power to cope with the larger search space required by the knowledge representation, and the required faster methods of processing. The inference engine mechanism, which is a combination of task sharing and result sharing perspectives, is distinguished into three phases of initialising, clustering and integrating. Based on a fitness measure derived to balance the communication and computation for the clusters, new clusters are assembled using genetic operators. The algorithm is also guided by the knowledge expert. A cost model for fitness values has been used, parameterised by computation ration and communication performance. Following the establishment of this knowledge representation scheme and identification of a supporting parallel architecture, a simulation of the array of PEs has been developed to emulate the behaviour of such a system. The thesis reports on findings from a series of tests used to assess its potential gains. The performance of the DPSS has been evaluated to verify the validity of this approach by measuring the gain in speed of execution in a parallel environment as compared with serial processing. The evaluation of test results shows the validity of the proposed approach in constructing large knowledge based systems.

Full textAbstract:
The interpretation of Nuclear Magnetic Resonance (NMR) spectra to produce a 3D protein structure is a difficult and time consuming task. The 3D structure is important because it largely determines the properties of the protein. Therefore, knowledge of the 3D structure can aid in the understanding of its biological function and perhaps lead to modifications which have an enhanced therapeutic activity. An NMR experiment produces a large 2D data spectrum. The important part of the spectrum consists of thousands of small cross peaks and the interpretation task is to associate a pair of hydrogen nuclei with each peak. Manual interpretation takes many months and there is considerable interest in providing (semi-) automatic tools to speed up this process. The interpretation is difficult because the number of combinations can quickly swamp the human mind and the spectrum suffers from peaks overlapping and random noise effects. ASSASSIN (A Semi-automatic Assignment System Specialising In Nmr) is a distributed problem solving system that has been implemented in the identification of peaks associated with the hydrogen nuclei at the end of long side chains. These results are then passed onto the structural assignment stage. The structural assignment stage is a feedback loop which involves the interpretation of a spectrum and the generation of preliminary structural models. These models can then be used to simplify further analysis of the spectrum. ASSASSIN uses a constraint manager implemented in CHIP to analyse this data more quickly and thoroughly than a human. The results of this work reveal that a constraint based approach is well suited to the NMR domain where the problems can be easily represented and solved efficiently.

This thesis investigates several issues in data and computation modeling for scientific problem solving environments (PSEs). A PSE is viewed as a software system that provides (i) a library of simulation components, (ii) experiment management, (iii) reasoning about simulations and data, and (iv) problem solving abstractions. Three specific ideas, in functionalities (ii)-(iv), form the contributions of this thesis. These include the EMDAG system for experiment management, the BSML markup language for data interchange, and the use of data mining for conducting non-trivial parameter studies. This work emphasizes data modeling and management, two important aspects that have been largely neglected in modern PSE research. All studies are performed in the context of S4W, a sophisticated PSE for wireless system design.Master of Science

Full textAbstract:
The problem motivating this research is that ineffective communication may hamper systems development efforts. Specifically germane to this study are development efforts characterized as task-oriented, and which require information-sharing and problem-solving activities. This research problem motivated an analysis of the communication process and lead to the development of a temporal framework that delineates variables associated with task-oriented, end user/systems analyst communication interactions. Several variables within this framework are depicted in two theoretical models. The first model shows the theoretical relationship between an independent variable, communication mode (represented by asynchronous computer conferencing and face-to-face conferencing), and five dependent variables: (1) the amount of information shared, (2) the significance of the information shared, (3) the comprehensiveness of the information shared, (4) the perception of progress toward the goal, and (5) the perception of freedom to participate. The second model depicts the assumed interaction between communication mode, the five variables cited above (now acting as independent variables), and a dependent variable, communication quality. There are two theoretical components of communication quality: (1) deviation from an optimal set of user requirements, and (2) the degree of convergence (unity based on mutual understanding and mutual agreement) emanating from a communication interaction. Using the theoretical models as a guide, an experiment was designed and performed to test the relationships among the variables. The experimental results led to the rejection of all null hypotheses; the results strongly favored face-to-face conferencing for solving task-oriented, information-sharing problems analagous to the case used in the present study. The findings indicate that asynchronous computer conferencing may have a detrimental effect on the thoroughness of information exchange, on the relevance of the information shared in terms of making the correct decision, and on the completeness of the consideration given to all problem dimensions.

Full textAbstract:
Organizations around the world have attempted to implement the concepts of the Toyota Production System (TPS), commonly referred to as Lean, with limited sustainable success. The central principles of TPS, continuous improvement and respect for people, are grounded in the Japanese values of Monozukuri and Hitozukuri. Monozukuri deals with creating or making a product, while Hitozukuri conveys the idea of developing people through learning. In order for organizations to adopt these values they must have a system that engages employees at all levels in applying problem solving to improve their work. This research uses organizational assessments obtained from a variety of organizations implementing the lean approach using the Monozukuri and Hitozukuri values, referred to as the True Lean System (TLS).
This research uses an inductive research approach to identify and analyze factors that impact the use of problem solving within organizations implementing a TLS. First, the qualitative assessment data is studied using textual analysis to identify themes impacting TLS. This analysis identified three topics as the highest weighted themes: number of problem solving methods, standardization, and employee roles. This qualitative data is then transformed using an integrated design model to systematically code the information into quantitative numerical data. Finally, this data was analyzed statistically by logistic regression to identify the factors impacting the use of problem solving within these organizations.
The results from the logistic regression suggest that the most successful problem solving organizations have established standards for work and training employees; as well as, a single problem solving method that all employees use when identifying and implementing continuous improvement ideas. Which leads to the conclusion, in order for an organization to sustain the concepts of TPS, there must be a focus on defining clear standardized work, training, and the implementation of a single problem solving method.

Redundancy Allocation Problem (RAP) is a well known mathematical problem for modeling series-parallel systems. It is a combinatorial optimization problem which focuses on determining an optimal assignment of components in a system design. Due to the diverse possible selection of components, the RAP is proved to be NP-hard. Therefore, many algorithms, especially heuristic algorithms were proposed and implemented in the past several decades, committed to provide innovative methods or better solutions. In recent years, multi-agent system (MAS) is proposed for modeling complex systems and solving large scale problems. It is a relatively new programming concept with the ability of self-organizing, self-adaptive, autonomous administrating, etc. These features of MAS inspire us to look at the RAP from another point of view. An RAP can be divided into multiple smaller problems that are solved by multiple agents. The agents can collaboratively solve optimal RAP solutions quickly and efficiently. In this research, we proposed to solve RAP using MAS. This novel approach, to the best of our knowledge, has not been proposed before, although multi-agent approaches have been widely used for solving other large and complex nonlinear problems. To demonstrate that, we analyzed and evaluated four benchmark RAP problems in the literature. From the results, the MAS approach is shown as an effective and extendable method for solving the RAP problems.

Full textAbstract:
The thesis examines some of the methodologies used for conflict study and analysis; it reviews Operational Research based approaches and methodologies from other areas of study that have been, and are still being used for the study and analysis of conflict situations in complex systems. The thesis argues against the prevalent use of single methodologies for such systems, and calls for the adoption of approaches that allows the use of multiple methodologies, which would place the emphasis on the "problem" rather than on any particular approach or methodology. The nature, causes and effects, ecology of conflict, and the concept of issue relevance and irrelevance are examined as well as the role of perceptions. The factors determining thedevelopment, level and scope of conflicts are reviewed with the aim of ascertaining their importance to conflict outcomes andwhen meaningful intervention could be made during conflict situations. Various outcomes of conflict, primarily management, dissolution, and resolution are discussed and their relative strengths and weaknesses as strategies for handling conflicts. Case studies are used to examine and support arguments about how different conflict outcomes arise and some proposals are made for the study of alternative futures. It is argued that undesired conflicts could be reduced or prevented in complex interaction systems through the deliberate design and incorporation, into such systems, of structures and mechanisms that will serve as integration systems. These integration systems involve all the parties in an interaction system and are intended to reconcile views, clarify positions, inform the parties about each other and assist in the formulation of joint responses to negative internal and external stimuli. An outline structure of an integration system is given and how it could be developed in a system. Many methodologies and approaches are based on the premise of a "prima facie" existence of a conflict; a tool is suggested in the thesis that will assist analysts, observers, or any interested party to monitor the relationship in an interaction system. This tool concerns what I have called the Y-points and Y-diagrams. The Y-concepts are based on the notion that there are periods in an interaction when a decision can be consciously taken to escalate or de-escalate a situation. The approach advocated in the thesis is based on two assumptions: the first is that the parties prefer a "normal" relationship to a conflictual one, the second is that the parties in a conflict would prefer the resolution of a conflict and its attendant stability to an unending management of the situation. Consequently, the main thrust of the arguments in the thesis is on conflict resolution and the design of stability into complex interaction systems.

This thesis describes user interface and visualization components in the problem solving environment "Site-Specific System Simulator for Wireless System Design" (S4W) developed by CS and ECE faculty and students at Virginia Tech. S4W integrates visualization and computational tools with a high level user interface. The objective of this PSE is to improve the ability of wireless design engineers to design an indoor wireless system through the aid of various simulation and visualization components. S4W provides engineers with the facility of thinking in terms of the overall task of designing the system for optimal performance. They need not to worry about computation, data-management and connectivity issues. The choice of method for interaction between service logic within a PSE and its user is always a challenging issue. The selection of user interaction channel is mostly dictated by the characteristics of the problem domain. For S4W, we chose to build a graphical user interface as human interaction interface, which was connected to other components via a high speed Local Area Network (LAN). The other key form of user interaction in a PSE is the visual representations of the abstract data results of simulations, perceived as user interface for data. The Complex nature of data sets in the domain of wireless simulations calls for a customized set of visualization tools. To address the specific needs of visualizations for S4W, ad hoc visualization tools were developed and integrated into the graphical user interface. A comparison of the integrated PSE and an earlier collection of unintegrated tools and scripts is presented.Master of Science

Full textAbstract:
The purpose of this study was to determine the effects of a feedback cycle on problemsolving groups. A formal method, Systematic Multiple Level Observation of Groups (SYMLOG), was employed for the analysis of behavior in such groups. The system, which codes on multiple levels of communication, served both as a theoretical and an explanatory approach. Problemsolving groups which included a feedback session on group process were compared with problemsolving groups which were not given feedback. The study used primary data from SYMLOG field diagrams to determine whether group movement, leader movement, self-perceptions, and group satisfaction would be affected by feedback intervention. Quantitative techniques were employed to answer the research questions. Case study techniques involving SYMLOG field diagrams were used to discuss the results in a descriptive manner. The groups were analyzed on multiple levels of space using the bipolar three-dimensional model of SYMLOG: task-orientation vs. emotionally expressive, dominant vs. passive, and positive vs. negative. Findings indicated that the feedback cycle played a central role in both group satisfaction and leadership behavior but had little effect upon group movement over time and did not appear to change self-perceptions in any substantial manner.

With the progressive development of the educational technology, online learning systems are becoming a prominent feature in education today. We conducted a study to explore the effects of visual cues and outcome feedback on learning experience of students in an online environment. Our study was a follow up study to a previous research, which demonstrated the effectiveness of visual cues and feedback to improve physics problem solving. The participants (N=164) were enrolled in an algebra-based introductory level physics course at a U.S. Midwestern University. Participants completed a sequence of conceptual physics problems in an online environment. The study used a between subjects 2×2 quasi experimental design. Two groups of participants received visual cues and two did not receive cues. Two of the groups of participants received outcome feedback and two did not receive feedback. The effect of visual cues, feedback and their combination on the correctness of students’ responses to the online questions was analyzed. Implications of the study for online learning systems are discussed.

Full textAbstract:
The purpose of this study was to revise and revalidate the scoring procedure of the DISCOVER Mathematics Assessment to allow evaluators to better measure creative problem solving ability in mathematics, identify gifted students, and evaluate the programs developed for fostering creative problem solving. The data for this study consisted of 233 students selected from five different grade levels. I conducted descriptive statistics and regression analyses to compare the relationships of both the original and revised versions of the scoring system with general creativity. I found that range increased from the original to the revised version of the scoring system for mathematical problem solving performance in semi-open-ended problems, however it decreased for overall performance and performance in open-ended problems. Variance, on the other hand, increased for both overall problem solving performance and performance in semi-open-ended problems, and decreased for performance in open-ended problems from the original to the revised version of the scoring system. Furthermore, in the revised model all three variables of the creative mathematical problem solving performance (overall performance, performance in semi-open-ended problems, and performance in open-ended problems) explained more variance in general creativity than the original version. Statistically, the differences between the original and the revised versions were significant for all three variables, except for creative mathematical problem solving performance in open-ended problems. Across grade levels, I found that for the group Lower Grade Levels (grade levels 1 and 2), the explained variance in general creativity increased from the original to the revised version for both overall performance and performance in semi-open-ended problems. However, it decreased for performance in open-ended problems. On the other hand for the group Higher Grade Levels (grade levels 3, 4, and 5) the explained variance in general creativity increased for all three variables from the original to the revised version. Statistically, the only significant difference between the original and the revised versions was for overall problem solving performance in Higher Grade Levels. I concluded that the revised version of the scoring system was more effective when predicting variance in general creativity for overall problem solving performance, and performance in semi-open-ended problems. Also, it predicted more variance in general creativity for the group Higher Grade Levels than the group Lower Grade Levels. Therefore, I suggested that quality should be considered as well as fluency, flexibility, and originality when scoring assessments for creative problem solving ability in mathematics.

Full textAbstract:
Over the past decade, two types of decision aids, i.e., decision support systems (DSS) and expert systems (ES), have been developed along parallel paths, showing some significant differences in their software architectures, capabilities, limitations, and other characteristics. The synergy of DSS and ES, however, has great potential for helping make possible a generalized approach to developing a decision aid that is powerful, intelligent, and friendly. This research establishes a framework for such decision aids in order to determine the elementary components and their interactions. Based on this framework, a generalized intelligent problem solving system (GIPSS) is deveolped as a decision aid generator. A relational model is designed to provide a unified logical view of each type of knowledge including factual data, modeling knowledge, and heuristic rules. In this knowledge model, a currently existing relational DBMS, with some extension, is utilized to manage each type of knowledge. For this purpose a relational resolution inference mechanism has been devised. A prototype GIPSS has been developed based on this framework. Two domain specific decision aids, COCOMO which estimates software development effort and cost, and CAPO which finds optimal process organization, have been implemented by using the GIPSS as a decision aid generator, demonstrating such features as its dynamic modeling capabilities and learning capabilities.

Full textAbstract:
Cette thèse a été initiée dans un contexte d’amélioration de l'expérience utilisateur (UX) pour l'analyse des données de Business Intelligence en raison de l'augmentation du volume de données liées à cette activité. D'une part, les besoins psychologiques des utilisateurs portent sur la simplification de l’utilisation des applications analytiques, ils font l’objet de plus en plus d’attention ; d'autre part, les tâches qu'ils sont prêts à mener deviennent de plus en plus complexes ce qui peut entraîner une surcharge de mémoire qui influe sur les performances dans leur réalisation. Pour garantir la prise en compte de ces deux aspects, les designers doivent concevoir des interfaces et fournir des informations appropriées qui répondent à la fois aux besoins des utilisateurs et aux nécessités de leur activité. Dans cette recherche, nous nous sommes intéressés à l'amélioration de la reprise de la tâche suite à une suspension ou à une interruption de celle-ci dans le cadre de l’analyse visuelle de données. La nature multitâche des actions des utilisateurs et les capacités limitées de stockage de la mémoire de travail humaine entraînent des difficultés à s’engager de nouveau dans une tâche qui a été interrompue ou suspendue. Il devient donc avantageux de disposer d'un outil de suppléance de la mémoire qui aide les utilisateurs à se remettre à leur tâche dans des conditions optimales.Une revue de la littérature nous a conduit tout d'abord au positionnement de notre recherche vis à vis de l'approche énactive et de la perception sensorimotrice qui considèrent l'outil comme un artefact configurant l'interaction entre l'utilisateur et la tâche, selon deux états, saisi ou déposé. De ce point de vue, nous avons constaté que le modèle de mémoire cognitiviste utilisé couramment ne considère pas le rôle de l’interaction avec le monde extérieur dans la construction de la mémoire, et par conséquent ignore la dimension saisie des supports et outils dans la construction d’une mémoire. Par conséquent, nous proposons de compléter ce modèle avec un modèle de mémoire incarnée, qui ouvre une nouvelle perspective permettant de concevoir un outil de suppléance mémorielle approprié. Enfin, les principes de conception d’IHM et d’UX nous aident à construire une proposition d’outil et à mener un plan d'expérience mettant en avant le lien entre les modifications des conditions de perception et les modifications de la dynamique d’interaction. En conclusion de cette partie, la problématique générale est introduite avec l’exploration, la mise en œuvre et l’évaluation de la proposition. La première expérience, le test pilote, analyse la perception que peuvent avoir des concepteurs naviguant sur des applications interactives. Cette étude nous a aidé à construire un vocabulaire d'évaluation en conception d’un support de suppléance de la mémoire et nous a guidé pour concevoir un processus expérimental en tenant compte de ces critères. Dans une seconde expérience, nous développons un outil basé sur une fonction que nous appelons le "history path". Cet outil permet d’afficher à l’utilisateur, dans une fenêtre spécifique de l’interface, certaines étapes de résolution d’une tâche antérieure effectuée par ce même utilisateur (ou pour simuler une interruption de tâche). Nous avons mis en place une expérience simple (minimaliste) simulant une résolution de problème qui a été enregistrée pour évaluer dans quelle mesure le history path peut aider l'utilisateur à récupérer efficacement une tâche interrompue. La première partie de cette expérience nous permet de confirmer l’utilité potentielle de cette fonction et nous aide à explorer l’espace de conception. Dans la deuxième partie, nous expérimentons deux outils différents basés sur deux représentations de l’history path, une représentation statique et l’autre dynamique. Les résultats de l'évaluation nous amènent à comprendre les conditions techniques d'une expérience positive pour laquelle la reprise de tâche est facilitéeThis thesis was initiated in the context of enhancing the user experience for analyzing data due to the increase of the volume of data related to this activity. On the one hand, users’ psychological needs for the simple use of analytic applications are paid more attention than before; on the other hand, the task they are willing to conduct is getting more and more complicated, which may cause memory overload that influences the task performance. To ensure that both aspects are taken into account, the designers should provide a proper information and design a proper interface that meets both users’ needs and the requirements of their activity. In this research, we are interested in improving the task recommitment following a task suspension or interruption in the context of a visual data analysis task. The multitasking nature of user actions and limited storage capacity of human working memory cause difficulties in re-engaging an interrupted or suspended task. Therefore, it is beneficial to have a memory supplementation tool that supports users to recommit their task in optimal conditions. A literature review first leads to the positioning of our research on the enactive approach and sensorimotor perception that consider the tool as an artifact configuring the interaction between the user and the task, in two modes the “put down” mode and the “in hand” mode. From this point of view, we have found that the commonly used cognitive memory model ignores the role of interaction with the external world in the formation of the memory, and consequently ignores the “in hand” dimension of the artifacts in one memory construction. Therefore, we complete this model with the embodied memory, which gives us a new perspective to design an appropriate memory tool that serves as a supplementation of our perceptual system. Finally, the design principles in human-computer interaction and UX helped us build a tool and conduct an experimental plan highlighting the link between changes in perception conditions and changes in the dynamics of interaction. As a conclusion, the research problem is introduced in terms of how we can provide users with a relevant context to recommit to resolving a task after interruption. The design proposal needs to be explored, designed and evaluated. The first experiment, the exploratory study, analyzes the perception of interactive applications by experienced designers. This study helped us construct a vocabulary of evaluation of the design for a memory supplementation support and guided us for the design considering these criteria. In the second experiment, we develop a tool based on a function that we call the “history path”, which permits to show, in a specific window of the user interface, some of the steps of a previous task resolution that a user has performed during previous experience (or to simulate a resolution task interruption). We set up a simple (minimalist) experiment simulating a problem-solving task, which was recorded to evaluate the extent to which a history path support can help the user for efficient recovering of an interrupted task. The first part of this experiment allows us to confirm the potential use of this function and helps us explore the design space. In the second part, we experiment two different tools, based on two history path representations, a static one and a dynamic one. The evaluation results allow us to understand the technical conditions of a positive experience for which task recovery is facilitated. In this second experiment, several means for recording the user experience were mobilized: the evaluation of the durations and gaze frequencies on area of interest in the interface window by eye tracking, the recording of the verbalizations during the RTA (Retrospective Think Aloud) session, and the semantic evaluation

Full textAbstract:
The purpose of the present study was to record Cedar Middle School's (CMS) response to intervention implementation journey. It is a qualitative case study that examines one school's efforts to bring school improvements under the response to inventory (RtI) umbrella in order to achieve a more systematic approach to providing high-quality educational services to every student enrolled at CMS. Participants included the 10 members of the school's Student Success Team along with the principal and assistant principal. The recorded journey included: (a) a description of the RtI consensus and infrastructure-building processes, (b) an exploration of the SST perceptions of school-wide intervention efforts both past and present, (c) a review of the school's accomplishments and the barriers to implementation encountered, and (d) the implications for further school improvement efforts and research. Participants submitted to interviews, observations, and focus group meetings. Although the purpose of the study was not to measure program effectiveness, preliminary data are included that report the school's efforts toward systems change was helpful for students and is having a positive effect on student performance in reading comprehension. Participants were also able to share anecdotal evidence of increased student motivation and other behavioral changes that were natural consequences of their efforts. This evidence is reported in the narrative found in Chapters IV and V. Conclusions were based on participant input, recorded measures, and analyses conducted as part of the present study. Cautions were also discussed, including the limitations and delimitations. Finally, implications of the present study were provided for RtI and the field of schoolwide systematic interventions and support.

La dispersion spatiale de l'habitat et des activités de ces dernières décennies a fortement contribué à un allongement des distances et des temps de trajets domicile-travail. Cela a pour conséquence un accroissement de l'utilisation des voitures particulières, notamment au sein et aux abords des grandes agglomérations. Afin de réduire les impacts dus à l'augmentation du trafic routier, des services de covoiturage, où des usagers ayant la même destination se regroupent en équipage pour se déplacer, ont été mis en place partout dans le monde. Nous présentons ici nos travaux sur le problème de covoiturage régulier. Dans cette thèse, le problème de covoiturage régulier a été modélisé et plusieurs métaheuristiques de résolution ont été implémentées, testées et comparées. La thèse est organisée de la façon suivante: tout d'abord, nous commençons par présenter la définition et la description du problème ainsi que le modèle mathématique associé. Ensuite, plusieurs métaheuristiques pour résoudre le problème sont présentées. Ces approches sont au nombre de quatre: un algorithme de recherche locale à voisinage variable, un algorithme à base de colonies de fourmis, un algorithme génétique guidée et un système multi-agents génétiques auto-adaptatif. Des expériences ont été menées pour démontrer l'efficacité de nos approches. Nous continuons ensuite avec la présentation et la résolution d'une extension du problème de covoiturage occasionel comportant plusieurs destinations. Pour terminer, une plate-forme de test et d'analyse pour évaluer nos approches et une plate-forme de covoiturage sont présentées dans l'annexeNowadays, the increased human mobility combined with high use of private cars increases the load on environment and raises issues about quality of life. The extensive use of private cars lends to high levels of air pollution, parking problem, traffic congestion and low transfer velocity. In order to ease these shortcomings, the car pooling program, where sets of car owners having the same travel destination share their vehicles, has emerged all around the world. We present here our research on the long-term car pooling problem. In this thesis, the long-term car pooling problem is modeled and metaheuristics for solving the problem are investigated. The thesis is organized as follows. First, the definition and description of the problem as well as its mathematical model are introduced. Then, several metaheuristics to effectively and efficiently solve the problem are presented. These approaches include a Variable Neighborhood Search Algorithm, a Clustering Ant Colony Algorithm, a Guided Genetic Algorithm and a Multi-agent Self-adaptive Genetic Algorithm. Experiments have been conducted to demonstrate the effectiveness of these approaches on solving the long-term car pooling problem. Afterwards, we extend our research to a multi-destination daily car pooling problem, which is introduced in detail manner along with its resolution method. At last, an algorithm test and analysis platform for evaluating the algorithms and a car pooling platform are presented in the appendix

Full textAbstract:
Manufacturers have to balance the desire for high productivity and the need for rapid responsiveness. These two interrelated problems can be solved by arranging the production of a family of modular products in Reconfigurable Manufacturing Systems (RMS). The potential benefits of RMS can be achieved by reconfiguring its structure in such a way that each configuration corresponds to one product variant in the same family. The successful implementation of this strategy lies in efficient scheduling of the system. However, little research has been done in addressing the scheduling issues in RMS. This study presents a modeling methodology to simultaneously determine the processing sequence of a family of modular products and select the optimal system configuration for producing each product variant. Due to the combinatorial nature of this problem, a genetic algorithm (GA) with parallel chromosome coding scheme is proposed to provide quick and near-optimal solutions to large problems. The efficiency of the proposed approach is demonstrated by comparing the computational results with that achieved using LINGO and by applying it to both small size and large size models.

All youth are faced with many social issues and problems on a daily basis, and youth in foster care are often less equipped than their peers to make good decisions for themselves. The SODAS problem solving method is a component of the Transition to Independence Process (TIP) model and is intended for personnel to use with youth to help them make better decisions when faced with difficult situations. The SODAS method is designed to guide youth through a problem solving method for a current situation, and over time to acquire improved problem solving skills. Three caregivers at a group facility for youth in foster care were trained in the use of the SODAS method using Behavioral Skills Training (BST) and were evaluated by the researchers in their use of SODAS in simulated role plays with the researchers and with youth participants to test for generalization of the SODAS method to novel situations. Results showed substantial improvement of caregiver application of the steps on the SODAS method from baseline to the post-training condition when researchers simulated the youth's role. Results also showed that caregiver proficiency generalized to novel situations presented by youth participants during their role play probes.

Full textAbstract:
In project or program planning, a Gantt or PERT chart is usually employed as a graphical representation of schedule for activities. Planners utilize this chart in performing analyses such as the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT). Very little effort, however, has been devoted to the formulation of activity networks, which is the initial step before aforementioned analyses. This research addresses this problem by developing a systematic methodology to aid in the identification and rapid structuring of a system of activities.
The theoretical foundation of the methodology is based on Interpretive Structural Modeling (ISM). It consists of seven basic steps: (l) identifying the activities in the set; (2) identifying the set of relation statements; (3)identifying the initial input; (4) establishing a transitive inference mechanism based upon previous responses; (5) generating a logical combination of relationships based on previous responses; (6) storing the relationship for each pair of activities in a relation matrix; and (7) outputting the relationships in the form of a simplified Gantt chart.
The merits of applying this methodology include (1) efficiency in activity structuring and (2) avoidance of illogical and inconsistent sequential relationship specifications. A "Business Appreciation" example is used in illustrating the application of this methodology. It reveals that 85% of a total of 120 possible sequential activity relationships can be deduced without asking for information from the user. In general, over 57% of the sequential relationships can be inferred without input by the user.Master of Urban and Regional Planning

Procedural Knowledge and Strategical Knowledge will construct the way of problem solving and Declarative Knowledge will set the environment of domain knowledge and construct the concepts of domain knowledge. Long-term memory and short-term memory construct the problem-solving memory system. Schema will combine these three types of declarative knowledge: propositions, images and linear orderings. It could organize the information of concept of domain knowledge. Concepts are elements of domain knowledge. The relations between concepts construct Concept Hierarchy. The structure of concept must find out the elements of concept schema and is constructed by schema. The problem structure is the first aim of problem solving. This paper will declare a problem structure for problem-solving strategies to analyze the meaning of problem. The production rules and operators construct the problem-solving strategies. The problem-solving strategies will use those rules and operators to solve a problem. Long-term memory is a knowledge base of problem-solving system and short-term memory is a working memory during solving a problem. Problem structure defines the structure of problem meaning. Problem-solving structure will analyze that structure and store the result into short-term memory. Problem-solving strategies operate based on states of problem. When problem states match the goal state of the current problem-solving strategy then this strategy completes its own task. This paper divides the procedures of problem solving into four solving strategies: Problem Identification, Problem Elaboration, Problem-solving Planning and Problem-solving Execution. This paper designs the long-term memory structure of junior high-school physics problem examples and takes several simple to construct problem structure. Problem identification will identify sentence patterns to redescribe the original problem. Problem elaboration will compare the concepts in the problem structure and those concepts in long-term memory to enrich the problem structure in the short-term memory. Problem-solving Planning sets the solving sequence based on the information in the short-term memory. Problem-solving execution will execute the problem-solving sequence to get the final answer.

Because modern society have demand on the time and cost as well as the popularity of computers, in order to effectively use time and reduce costs, so makes the real-life problems simply into mathematical models that can be calculated, such as traveling salesman problem (TSP), vehicle routing problem (VRP), quadratic assignment problem (QAP), and so on. TSP is an optimization problem for salesman to obtain the minimum distance, its wide range of applications, such as scheduling, transportation, chemical engineering, electronic engineering and other issues, all can be transformed to TSP. Since the first ant algorithm, Ant System (AS) was developed, there were many scholars devoted to improve ant algorithm. Ant algorithm has been applied to solve many Combinatorial Optimization Problems, such as TSP, VRP, QAP, and so on. This paper present the Distance Weighted Ant System (DWAS), an ant algorithm improved for pheromone evaporation. DWAS differs from other ant algorithms in pheromone evaporation, whose makes evaporation rate along with the length of distance will vary. This paper used three TSP instances from TSPLIB to test, and the TSP instances were eil51, kroA100, d198, afterwards, compared with AS, Ant Colony System (ACS) and MAX-MIN Ant System (MMAS). The compared results show that: on the same number of tour constructions, DWAS only slightly better than AS in d198, the other results are worse; DWAS’s number of tour constructions was double, DWAS are better than AS, but still worse than ACS and MMAS.

Solving traveling salesman problem (TSP) by integer programming we often spend a lot of time and inefficient when the problem scale to be large. For this reason, in order to improve efficiency the Meta-Heuristics become more important gradually such as Genetic Algorithm (GA), Tabu Search (TS), Simulated Annealing (SA), and Ant Colony Optimization (ACO), etc. This study developed a new improved MMAS algorithm Weighted Max-Min Ant System (WMMAS), global best and iteration best are two information been used, and weight are used into pheromone mechanism, it was changed by iteration increasingly. In the initial stage, we expect more width search space, and global best are the major information that leads to a better search space in the final stage. We uses eight international exemplars for testing in this study, and use exchange method solve large problems. Compare the results between WMMAS and MMAS, in each eil51, kroA100 and d198 reduce 0.38%, 0.17%, 0.24%, and result are compared with the results from other revised algorithms are improved. Compared result with WMMAS+3-opt and MMAS+3-opt, it’s gaps are better than MMAS+3-opt. At solving time, only at pcb442 and att532 difference are bigger, the other are small.

M. Tech. Electrical Engineering.Discusses the practical management of electrical networks, no perfect monitoring of an electrical power system state is available, either because it is expensive or technically unfeasible due to the poor quality of the available measurements in the control centre. To have a stable network, the control centre must receive the network information to be able to provide a proper security in unforeseen situation. As a power system network is a complex and a non-linear system, it is important to use more advanced methods for its analysis and control in a real time environment. The aim of this research work is therefore, to apply several state estimation algorithms using artificial intelligence by developing their mathematical models for the purpose of comparing their performances in estimating the state variable of the power system. The three types of state estimation algorithms investigated for this research work are: the Particle Swarm Optimisation (PSO), the Genetic Algorithm (GA) and the Newton method for state estimation (NSE).

Electronic commence has become an important business model in recent years due to the advent of computer and network technologies. The number of enterprises that employ e-commerce systems to offer various on-line services has increased rapidly, and hence the issue of developing more effective e-commerce systems has attracted researchers from the fields of both computer science and business. One of the most challenging issues of e-commerce is the reliability of developed systems. The failure of an e-commence system will lead to significant loss since business transactions cannot be completed and the credit of the enterprise could be damaged. Usually a system failure cannot be predicted. It can be found only after users or the administrator discover the failure and resolve it. Currently, there are some monitoring systems of e-commerce systems developed. However, those systems can only notify system administrator after a failure occurs. They cannot predict possible failures and notify the system administrator to avoid the problem. This thesis proposes the development of an Event-Driven Control System (EDCS) which provide a reliability-oriented e-commerce environment. The system can monitor e-commerce systems on situations that may cause system failures, and do compensation procedures automatically, semi-automatically or manually to avoid the occurrences of failures. EDCS is helpful for the system administrator to monitor potential problems and avoid them, and hence the system reliability can be significantly improved.

Since the beginning of 1990s, Taiwan has been one of the most important OEM/ODM partners partner. These firms are valuable because of their production speed, flexibility, and cost-cutting ability. But nowadays, when business environment is getting more competitive; demand is uncertain; and technology is rapidly changing, the cost-cutting ability of OEM/ODM becomes more challenging than ever. In such situation, purchasing function, which directly effecting to cost structure, product quality, and competitive ability of enterprise, becomes an essential function. So, the understanding of supplier behaviors and effect of these behaviors on firm operation becomes an indispensable tool for managers for making adequate strategic decisions on supplier evaluation and selection. This research develops a system dynamics (SD) model to (i) investigate the effects of supplier’s behavior on a firm performance and (ii) to process supplier evaluation and selection work. A simulation model is designed based on actual operation of a Taiwan ICT firm, including five internal sub-models: order demand, production control, financial planning, project management, R&D, and an external sub-model: supplier management. In order to confirm the accuracy of simulation model, structural validity tests and behavior validity test are applied. A set of design of experiment (DOE) is designed to investigate the effect of supplier factors on profit outcome. Furthermore, historical data from 18 housing material suppliers are loaded into the proposed SD model to implement the supplier evaluation and selection process. Our study also proves that the combination of the most efficient suppliers produces a higher profit, approximately 8%, comparing to simulation result of 18 suppliers.

During the process of learning inside classroom, the student increases the recognition and the trust via cooperative processing, to produce much more learning efficiency. However, this efficiency is most likely restricted by the space available in class during team problem solving and group learning processes, which affects the learning effect of students. With science and technology changing rapidly, the streaming technology becomes the mainstream of internet transmission media. Due to the technology, many social media and video sharing websites release live streaming feature to provide better user experience to the users. Media streaming technology improves the speed of sharing information between people. Therefore, to establish the information sharing platform with streaming technology brings enormous benefit to students’ learning effect. As mentioned previously, this study aims to develop a multi-user problem solving system based on streaming technology. The purpose of this system is subdivided into the following two parts. First, the system shares the cooperative learning process and the problem solving process of each team to maximize the knowledge gain of every students in class. Second, the teacher shall teach students with our system combining with interactive whiteboard to increase the learning efficiency and the learning experience of students, and to improve the interactivity.

MathCAL-II is a piece of software for students to practice solving mathematical word problems in trigonometry. At the core of the system is a database that stores experts’ problem-solving paths. These solution paths are stored as Petri net graphs internally. MathCAL-II also dynamically records a learner’s solution path during a practicing session. Thus it can compare a learner’s partial solution path against all correct solution paths to identify a best match, which can then be used to provide guidance to a learner in case s/he requests help. In a series of experiments that we conducted in a local high school, 58 students who participated voluntarily were divided randomly into the treatment group and the control group. The treatment group used MathCAL-II to practice solving trigonometric word problems, whereas the control group used the traditional pencil-and-paper approach. Results revealed that the students in the treatment group made significantly more progress than those in the control group. A questionnaire survey also showed that MathCAL-II not only improved students’ understanding of mathematical concepts in trigonometry but had positive influence on students’ attitudes toward learning trigonometry.

This paper focuses on the problem and knowledge structure in Inter-correlated Knowledge, which usually exists one Core Knowledge Object for presenting central idea of the knowledge. Problems can be separated into two types: basic problem and complex problem. In Inter-Correlated Knowledge, the definition of a basic problem is a problem which exist only one Core Knowledge Object, which means a basic problem can be decomposed based on Core Knowledge Object from a complex one. Two problem structures are also proposed in this paper, Problem Graph and Problem Matrix. The knowledge structure used in this paper is Knowledge Map. Knowledge Map comes from the idea of “concept map” and “schema”. Two major elements existing in Knowledge Map: Concept Hierarchy and Concept Schema. This knowledge structure could not only be used for constructing problems but also be used for solving problems, which is according to four knowledge types of formatting and assessing schema proposed by Marshall in 1995. The problem solving strategies are Problem Identification, Problem Elaboration, Problem Planning, and Problem Execution. Another topic of this paper is the difficulty of a problem. Eight Difficulty Features are analyzed according to the central concepts (Core Knowledge) and unknowns in the problem. To make problem solvers understand more detail of their troubles in problem solving, the transformation from Difficulty Features to Difficulty Dimension, which is analyzed by problem solving strategies, is important. The four Difficulty Dimensions defined according to four problem-solving strategies, which are Problem Identification, Problem Elaboration, Problem Planning, and Problem Execution. To realize the previous analysis of problem model, an item generation system with problem solving analysis has been designed and realized in this paper, which is named Problem Solving Trainer. Four major elements exist in it: Long-Term Memory, Short-Term Memory, Item Generation System, and Problem Solving System. Using this system architecture, problem solver can practice different concepts of problems from Item Generation System and ask for help by Problem Solving System when they get trouble.

The experiment lasted for six weeks, totaling 320 minutes, data collection and analysis, and quantitative statistics.In addition to using the programmatic inquiry system, the research tools used the CTS scale developed by Korkmaz, Çakir, and Özden (2017), the PSI scale developed by Heppner and Petersen (1982), and Glass and Benshoff (2002). The team develops strength tables. In this study, the "single group pretest-posttest design" of the experimental research method was used for the study, and the pretest questionnaire was completed before the experiment teaching. After the end of the teaching, the posttest was performed. The quantitative data were statistically compared with the Paired-Samples t test. Semi-structured interviews for an in-depth analysis of changes in team cohesion.Based on the results, this study believes that the Monographic Exploration Activities Programming System does help to improve the problem solving ability and team cohesion of the elementary school students. According to the content of the interviewed participants, during the team's creation of the topic, the participants will be able to improve their information skills through peer assistance, and they will be able to face problems and gain positive growth.
