Full textDistributed systems are composed of geographically distributed computing elements that belong to multiple administrative domains and are controlled by multiple entities. These characteristics from distributed systems make hard the task of testing and evaluating software for this platform, because it is unlikely that testers/system or policy evaluators are able to acquire repeatedly the same re- sources, for the same amount of time, and under the same network conditions, which are paramount requirements for enabling reproducible and controlled tests in software under development. An al- ternative to experiments in real testbeds is emulation, where a model of a system hosts the actual software under test. Virtualization technology enables development of efficient emulators because it offers means for resources multiplexing and isolation. Even though virtualization makes easier development of emulators, there are few efforts in isolating testers/system or policy evaluators from operation of the virtualization tools and environment. This thesis presents Automated Emulation Framework (AEF), which applies virtualization and systems management technology in a cluster of workstations to provide testers/system or policy evaluators with a tool for automated emulation of distributed systems. Three main activities are performed by AEF. First, it performs the mapping of virtual machines that represents nodes from the emulated distributed environment to cluster nodes and emulated links between virtual machines to paths in the physical network; second, it performs automated installation and configuration of virtual machines in the cluster and virtual network in the cluster network; third, it performs automated configuration and triggering of experiments in the emulated system, monitoring and control of environment and applications, and system reconfigu- ration in case of violations in the tester/system or policy evaluator demands. Regarding the first activity, the mapping problem is formally defined and four heuristics for solution of the problem are developed and evaluated with the use of discrete-event simulation. Regarding the last two activities, AEF architecture is described in details. Furthermore, an AEF prototype is developed and evalu- ated by execution of experiments in the context of grid computing. Experiment results show that implementation of the architecture is feasible and that AEF can be a valuable tool for repeatable and controllable distributed systems experimentation.

Full textWith technology advancing, more and more people turn to the World Wide Web to conduct business. This may include buying and selling on the Web, advertising and monitoring of business activities. There is a big need for software and systems that enable remote monitoring and controlling of business activities. The Mechatronics Research Group of the Faculty of Engineering, Information and Communication Technology at the Central University of Technology, Free State, has identified a similar need. This research group has created an Automated Manufacturing System around which research topics revolve. They want to monitor this Automated Manufacturing System from remote locations like their offices or, if possible, from home. The Remote Information Management (RIM) System was developed, using the Rapid Application Development (RAD) Methodology. The reasons why this methodology was used, is because it is the best to use in a changing environment, when the system needs to be developed very quickly and when most of the data is already available. This is a good description of the Automated Manufacturing System’s environment. The RAD methodology consists of four stages: Requirements Planning, User Design, Rapid Construction and Transition. Project Management is used throughout these stages to ensure that the project goes according to plan. Development of the RIM system went through all four stages and project management was applied. The final system consisted of a Web Page with Web Camera views of the Automated Manufacturing System. The application that was developed using National Instruments LabVIEW, Microsoft Visual C++, and Microsoft Excel, is embedded in this Web Page. This application is called a Virtual Instrument (VI). The VI shows real-time data from the Automated Manufacturing System. Control over the VI can be granted and will allow the remote user to create reports on how many different products was produced and system downtimes. A system like the RIM System has advantages in the business world. It can enable telecommuting and will allow employees and managers to monitor (and even control) manufacturing systems, or any system connected to a PLC, from remote locations.

Company A's Product Group B (PGB) is developing an automated system to complete final assembly of the Component, a structural member of the product that includes technology supporting two features of the product's competitive advantage. PGB contracted with an industry partner to supply the automated assembly system, which will be built and tested in 2015. Amid the wide spread perception that automation projects purchased from suppliers include schedule delays and performance deficiencies, PGB must specify the activities to verify automated assembly system performance prior to purchasing it from the Supplier. Interviews with project teams were completed to gather data about the procurement of existing automated systems at Company A. A range of success in completing project buyoff on time with no deficiencies was found with variation in buyoff results mainly associated with the presence or lack of fully-defined requirements and detailed procedures to verify and validate the system according to the requirements. The findings led to the hypothesis that automation system buyoff can be improved by applying an approach that includes development of good requirements, planning detailed procedures to verify and validate the system according to the requirements, and tracking progress towards meeting requirements to a schedule. To test the hypothesis, an approach to buyoff plan development and execution incorporating these factors was defined and then evaluated using a model. Buyoff of the automated assembly system will occur in 2015 according to the approach defined in this research. Results should be evaluated to validate the hypothesis and provide evidence for further buyoff plan improvement.

The Boeing Company is looking to bring aircraft manufacturing technology into the 21st century. As part of this process, several projects have been started to develop the technologies required to achieve Boeing's vision for the future of aircraft manufacturing. To date, much of this work has focused on hardware, including robotic and other automation technologies. However, in order to use this hardware, a significant effort must also be made in the area of factory control and coordination. This thesis advances knowledge in this area by evaluating the suitability of different control system approaches for aircraft wing box assembly. First, general classes of control systems are discussed and several criteria are proposed for evaluating their performance in an aircraft manufacturing environment. The current wing box assembly process is then examined in order to develop simplified but representative task networks to which various algorithms can be applied. The Tercio algorithm, developed at MIT, is used to generate schedules for several problem structures of interest in order to characterize the algorithm's performance in this context. The Tercio algorithm is then benchmarked against the Aurora scheduling tool, showing that Tercio can generate more efficient schedules than Aurora, but at the cost of increased computation time. Next, management considerations with respect to product design, manufacturing technology development, and implementation associated with advanced manufacturing technologies are discussed. Finally, recommendations are provided for how Boeing can accelerate the development of useful and practical advanced, automated manufacturing systems.

With the increased application of cognitive computing across the spectrum of industries, companies strive to ready their people and machines for future system change. Based on resource constraints, business needs, and the speed of change, many companies may opt for system augmentation rather than the adoption of entirely new systems. At the same time, changes in technology are increasing at paces never before realized. Against this backdrop, human actors and machines are working together interactively in new and increasing ways. Further, recent business model innovations, particularly in the retail space, have cast focus on logistics execution as a potential major competitive advantage. In this context, we considered the conceptual question of how best to iteratively improve a logistics planning system, which is composed of both human and machine actors, to reduce transportation and labor costs and increase the ability of the organization to think and act strategically.
In order to front these current technological realities - the need to stage for agent based systems and cognitive computing, the likelihood of system retrofit over rebuild, the ever increasing rate of change, and the rapid intertwining of human and machine roles - we proposed using human-machine interaction (HMI) design paradigms to retrofit an existing loosely coupled human-machine planning system. While HMI principles are normally applied to tightly coupled systems such as jet airplanes, the HMI architectural design applied novelly in this case showed significant application to an existing loosely coupled planning system. In addition to meeting the realities of today's competitive landscape, the developed HMI framework is tailored to a retrofit situation and also meets resiliency considerations. That novel conceptual proposal of HMI frameworks to an existing loosely coupled joint cognitive planning system shows tremendous promise to address these imminent realities.
With regards to the particular freight planning system considered, 71% of manual interventions were caused by the wrong sourcing facility being assigned to supply pallets to a customer. The remaining intervention causes were carrier changes 18%, customer restrictions 9%, and one change prompted by a data discrepancy. Further, at a conceptual level, the application of HMI frameworks to an existing freight planning system was effective at isolating data and alignment incongruences, displayed lower communication costs than recurrent system rework processes, and tethered well with system resiliency factors.

In 2003 Kiva Systems (now Amazon Robotics) introduced a new type material handling automation to the world. The system is based on the principle that the physical infrastructure that contains inventory should be mobile. Kiva achieved this remarkable advancement by employing a fleet of robots to move shelving to human operators. Broadly, these types of systems are defined in the literature as multi-agent robotic systems. Amazon acquired Kiva Systems in 2012 to incorporate the technology into their operations. The goal of this thesis is to optimize the throughput of warehouses employing multi-agent robotic automation. It is assumed that extracting inventory from the automated system is the limiting factor in maximizing throughput (i.e. downstream process are unconstrained). Two strategies are advocated: 1) performing velocity segregation of inventory within the automation via a bifurcation between fast selling and slow selling inventory, 2) maximizing pick rates through policies that increase worker retention. It will be shown that velocity segregation increases machine efficiency by increasing the efficiency of delivering inventory to human operators. This assertion will be investigated by developing a theoretical understanding of how inventory velocity impacts machine efficiency and simulating different types of stow strategies impact on system efficiency. It is estimated that some stow strategies can increase machine efficiency by as much as 30%. It will also be shown that the number of man-hours worked by inexperienced pickers explains practically all of the variability of aggregate pick cycle times and hence pick rates, which motivates the argument for worker retention. Together, these two modifications are estimated to increase throughput by 10% over current baseline.

The content of this thesis draws heavily on work completed during a 6.5 month MIT Leaders for Manufacturing (LFM) internship at Dell Corporation's personal computer manufacturing facility in Lebanon, Tennessee (EG1) from June 2004 to December 2004. This work relates primarily to efforts to analyze and improve the throughput of the Automated Storage and Retrieval System (ASRS) in that factory. Wherever possible, the thesis abstracts from the EG1 factory case study to provide lessons for improving the throughput of ASRSs and accumulative manufacturing systems in general. In addition to this core of the thesis, specific implementation challenges encountered during the EG 1 case study are addressed. Finally, general cultural observations about Dell's manufacturing environment are discussed. The author believes the two most unique aspects of this work are the Crane Frontier framework developed for analyzing ASRS throughput (Section 2.6) and the range and taxonomy of ASRS throughput improvement solutions (Chapter 3).

Full textThis thesis investigates the impact of the introduction of alternative project delivery systems to the traditional on the competitive strategies of construction firms. The work focuses on project delivery systems from a construction company perspective, and draws from the experiences an over the world for its findings. A literature review of project delivery systems, their evolution and introduction was undertaken in depth. This showed the types of delivery systems: their advantages and disadvantages and the reasons they were preferred. A review of strategy was then undertaken to introduce and discuss the concepts that influence competing firms. The construction industry has unique characteristics that differentiate it from other industries. A short discussion of these characteristics and how they influence strategy in construction companies was therefore done. This then led to a review of strategy in the construction industry. The concepts of project delivery and strategy in construction companies were then linked to show, with illustrations, how delivery systems are used as competitive strategy. To investigate the topic further construction companies were surveyed to find out the connection between the two concepts. It was found that alternative delivery systems are increasingly being used by the firms. They were also familiar with concepts of formal strategy and were actively using such concepts. Firms were found to be using delivery systems specifically as a competitive strategy and intended to do so more in future. The findings suggest that the use of delivery in such a manner was not the result of a deliberate plan but more a reaction to the changes in the industry. Construction firms need a greater appreciation of the role of project delivery systems in their strategy as this will help them achieve their objectives better, and result in a more efficient industry.

Full textThe construction industry is reputedly lethargic to adopt innovation and, in particular, new technology. To date it has not readily embraced Information Technology (IT) given its reluctance to recognise the many potential efficiencies and competitive advantages afforded by this technology. Where IT in the form of Information Systems (IS) has been introduced the likelihood of failure and/or inefficiencies is large considering the historic inability of IS to deliver on its potential. Furthermore, this performance of IS is arguably dependent on the role of the Chief Executive Officer in the construction organisation.This study examines the performance of IS in the construction firms and the role played by the CEO in that performance. The study has four main objectives; namely: (1) to determine the role of the CEO of construction companies relative to IS governance and performance; (2) to determine the role of the CEO of construction companies in determining the structure of IS to strategically support the company; (3) to examine the relationship between the CEO and Chief Information Officer (CIO) and the impact of this relationship on the performance of IS in a construction firm;and (4) to examine the importance of information processing and knowledge management of construction companies.To achieve these objectives, the literature on IS performance in the organisation was reviewed; a structured self-administered questionnaire survey was conducted of a sample of executive managers drawn from 9 construction companies; the data was analysed; the findings discussed against the background of the literature reviewed.The key findings of this study indicate that most of CEOs of construction companies consider IS performance as of strategic importance in their organisations with respect to information processing and knowledge management; and acknowledge the important role of the CIO in IS governance and information management. Furthermore, the CEOs also acknowledge their role in organisational design, and the structuring of IS to strategically support their companies. Drawing from the responses of a sample of CEOs of contracting firms in the Western Cape province of South Africa there appears to be a direct correlation between the role of the CEO and IS governance and performance.
