This project is an assessment of the NAVCENT logistics system as it relates to support of naval expeditionary units such as Naval Construction Forces (NCF), Naval Special Warfare (NSW) forces, Explosive Ordnance Disposal (EOD) units, and Fleet Hospitals. Based on literature from strategic management, logistics, and supply chain management, the research evaluates the existing theater logistics capabilities and the requirements of the supported expeditionary units. Due to the current world situation and availability of information, the focus is on the U.S. Naval Forces Central Command (NAVCENT) Area o Responsibility (AOR). A key finding is that the NAVCENT logistics system is adequate, but inefficient. Adequacy points to the fact that the resources and capabilities are in place in theater, while the inefficiencies are explained by lack of execution. The report recommends increased integration, awareness and doctrinal understanding in order to improve the NAVCENT logistics system. Sponsorship is provided by the Naval Operational Logistics Support Center, a newly created organization that serves as the focal point for operational logistics in the Navy and Marine Corps.

Yzdanye «fynansovaia hazeta-ekspo», №5, 2007.Marketing and logistics represent some of the key areas of companies’ activities that have direct impacts on the volume of goods sold and establish distribution strategy for the company. They directly affect each other's activities and can dramatically change the company's market position through the integrated development of the both areas. The main purpose of the above types of activities is the distribution and sale of goods. Effective supply chain and logistics management play a key role for customers, suppliers, owners and investors of any company as this activity coordinates and connects all structures of the organization. The field of logistics covers the management of a wide variety of objects – flow of documents, information, finance, people, and, of course, goods and materials flow. Decisions made in the distribution area must go primarily in accordance with the decisions in the production and marketing area. Logistics experts make decisions on such issues as distribution routes, store`s type and location, sales format etc.

Full textAbstract:
The military community has considerable experience in the areas of procuring and managing large systems. These systems are often expected to perform their intended function over a period of several years and as a result, they will require an extensive support structure consisting of personnel, equipment and spare assets. For this reason, Logistics Management has always been an important field within the military and is gaining recognition within private industry as well.
The evolutionary process which starts with the identification of a need and continues through design, production and retirement is known as a product's life cycle. Studies have shown that the decisions which are made initially, during the design of the product, will determine 80% of the total system costs. Several efforts have been initiated to improve the product design process and emphasize the life cycle approach. These include; Concurrent Engineering, Logistics Support Analysis (LSA) and Quality Function Deployment (QFD).
These efforts necessitate an overhaul of the decision-making methods used in the product design process. Consequently, within the military community and private industry, the time-honored sequential-hierarchical-decision approach to design is being replaced with concurrent decision-making. The sequential process of the hierarchical method can lead to suboptimal designs which significantly increase manufacturing and follow-on support costs.Ph. D.

Full textAbstract:
It has long been recognised that, in the military sector, the Integrated Logistics Support ILS can significantly enhance system effectiveness and add value to their competitiveness. Hence, it is not surprising that many organisations outside to the military support the ILS adoption to increase their competence level. Even though the ILS underlying theory is general, there is a lack of suitable methodology that facilitates ILS implementation in other industries such as Oil & Gas industry. In particular when considering complex systems with long life-span, the optimisation of maintenance-related activities is important to fulfil system readiness, safety and whole life cost requirements. Modern petroleum equipment like gas turbines and drilling rigs are dependent on readily available maintenance supports in order to maximise their operational ability. Therefore, it has been identified that the study should be conducted to an effective use of ILS with the petroleum industry. In doing so, the usage of the ILS framework as a decision tool for maintenance optimisation is outlined. This framework embraces ILS concepts to support asset managers in developing their maintenance strategies. Level of repair analysis and spare parts management have been identified as potential areas for enhancing the use of ILS. In particular, maintenance optimisation is approached as a trade-off between investment in spare parts level and repair capacity. The developed framework delivers cost-effective support strategies obtained with iterative optimisation algorithm built on heuristics and genetic algorithm techniques. Finally, this algorithm has been implemented into computational algorithms. The framework can be employed to identify the optimum level of spare parts and the optimum amount of repair capacity for multi echelon repair network and multi-indenture systems. The framework has been used to carry out optimisations intended to maximise the availability of gas turbines by varying logistics support parameters. Typical results have shown that a joint optimisation of spare parts and level of repair analysis leads to better results than optimising them separately and emphasises the need for the developed framework. As part of this research, an expert panel validation method has been used to both refine the design of the developed framework and also evaluate its functionality from experienced practitioners within the Algerian petroleum industry. The results of this validation have demonstrated the advantages of integrating spare part management and level of repair analysis LORA to the problem of maintenance optimisation and shown that the framework is able to deliver optimal maintenance supportability decisions. The generic framework developed in this thesis can be seen a novel and comprehensive model for integrating two ILS elements into the operating tool in a manner that improves maintenance support provision, while remaining both flexible and usable; and therefore as a contribution to a better adoption of ILS technique within Algerian Petroleum Industry.

Approved for public release; distribution is unlimitedLegacy logistics systems are an antiquated technology and fall short of providing the Marine Air Ground Task Force (MAGTF) with modern, net-centric, expeditionary Logistics Chain Management (LCM) and Command and Control (C2) capabilities. The Marine Corps owns more than 200 logistics information systems. While some of these systems still perform critical functions, others are stove-piped, redundant, or no longer provide an adequate modern capability. Managing legacy assets and interim technologies while concurrently developing new long-term enterprise solutions is required in order to provide the Marine Corps with the necessary logistics information technology capabilities. The envisioned future end state is logistics data shared across the MAGTF, and ultimately, across the entire organization. A shared-data environment, populated by autonomic computing, will provide actionable logistics data to everyone in the MAGTF, from the warehouse to the warfighter position, in near real-time. Common systems supporting common techniques, tactics and procedures which equal significantly improved capabilities. The goal of this research is to envision a set of common information technology capabilities required to execute LCM missions without considering the current limitations provided by existing legacy or MLS2 information technology systems. This research will focus on implementing a service-oriented architecture (SOA) approach to the MLS2 and related processes that will initiate to improve support to the decision-makers and the warfighters across the enterprise. The key end state at hand is to determine a mutually exclusive and comprehensive set of common MLS2 information technology capabilities required to execute C2 for Logistics and LCMs missions.

Full textAbstract:
This thesis describes the development and application of a decision support
system for logistics strategy modelling. The decision support system that is
developed enables the modelling of logistics systems at a strategic level for
any country or area in the world. The model runs on IBM PC or compatible
computers under DOS (disk operating system).
The decision support system uses colour graphics to represent the different
physical functions of a logistics system. The graphics of the system is machine
independent. The model displays on the screen the map of the area or country
which is being considered for logistic planning.
The decision support system is hybrid in term of algorithm. It employs
optimisation for allocation. The customers are allocated by building a network
path from customer to the source points taking into consideration all the
production and throughput constraints on factories, distribution depots and
transshipment points.
The system uses computer graphic visually interactive heuristics to find the
best possible location for distribution depots and transshipment points. In a
one depot system it gives the optimum solution but where more than one
depot is involved, the optimum solution is not guaranteed.
The developed model is a cost-driven model. It represents all the logistics
system costs in their proper form. Its solution very much depends on the
relationship between all the costs. The locations of depots and transshipment
points depend on the relationship between inbound and outbound
transportation costs.
The model has been validated on real world problems, some of which are
described here. The advantages of such a decision support system for the
formulation of a problem are discussed. Also discussed is the contribution of
such an approach at the validation and solution presentation stages.

Full textAbstract:
In the 1990s, the UK construction industry directed considerable effort at improving productivity and reducing costs by harmonising relationships among clients, contractors, sub-contractors, specialist contractors and designers. Opportunities to accrue further benefits should be explored and capitalised upon from all areas of construction projects. Management of construction materials on well grounded logistics and supply chain management principles has the potential to yield results and augment efforts being made in other areas at making construction more efficient. The overall aim of this thesis was to develop a systematic supplier management decision-support process model that contractors can use for both short and long-term management of suppliers in the implementation of construction materials supply logistics. Such a process model would benefit construction companies by identifying essential elements that lead to improved supply of construction materials. The research findings were based upon a literature survey, two `minor-image' questionnaires (one sent to 71 UK contractors and the other to 76 UK construction materials suppliers); structured interviews with nine UK contractors and five UK construction materials suppliers; and a supplier management process model validation exercise with six UK contractors. From these, the research produced the following outcomes: systematic supplier management decision-support process map that contractors can use for short and long-term management of suppliers in the implementation of construction materials supply logistics; an understanding of the supply of construction materials into construction processes from the wider perspective of logistics and supply chain management as opposed to traditional materials management; the identification of the performance indicators against which the performance of suppliers can be evaluated and the quantification of the relative contribution of the performance indicators to improvements in customer service; the identification of factors which enable suppliers to improve levels of customer service and quantification of the relative extent to which the factors enable suppliers to contribute to improvements in their levels of customer service in the delivery of construction materials; identification of the extent to which both performance indicators and enablers were used in supplier evaluation and selection; evaluation and comparison of the extent to which contractors and suppliers used information and communication technologies in internal and external materials supply logistics processes; and evaluation of the nature of relationships between contractors and suppliers.

Full textAbstract:
As a crucial factor for forming a competitive supply chain, the supplier selection problem has gained a lot of attentions from both researchers and practitioners. To fulfil the increasingly stringent environmental regulations and meet the NGOs’ and customers’ call for environmental conscious and socially responsible business, companies find it necessary to incorporate environmental and social dimensions in the supplier selection process.
This thesis presents a supplier selection-model incorporating the sustainability issues. Firstly, a comprehensive set of sustainable supplier selection criteria are identified. Then, a hybrid multi-criteria decision making (MCDM) model comprising the fuzzy TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) and the two-level DEA (Data Envelopment Analysis) algorithms is developed to screen out less qualified suppliers.
To begin with, twenty one supplier selection criteria are defined in the categories of economic performance, environmental impacts, and corporate social responsibility (CSR) impacts. The criteria were identified from literature review and a small-scale consultation with industrial practitioners. Regarding the economic criteria, quality, delivery, production capacity, cost, technical capability, financial position, management & organization and reputation are the more important aspects. For environmental impacts, most frequently adopted criteria are targeted at measuring supplier’s current environmental performances, i.e. negative impacts of products and production process on the environment. For CSR impacts, labour, health and safety criteria are received the most attention.
A hybrid supplier pre-selection model consists of the fuzzy TOPSIS and the two-level DEA is implemented to shortlist suppliers. The fuzzy TOPSIS is used to measure the supplier’s outcome based performance, while the two-level DEA is used to measure the supplier’s efficiency, that is, how efficiently the supplier uses various resources to achieve that level of performance. With the combination of the performance score and the efficiency score, suppliers are grouped in to four clusters, that is, high performance and efficient (HE), high performance and inefficient (HI), low performance and efficient (LE) and low performance and inefficient (LI). Improvement targets for suppliers in HI, LE and LI clusters are identified.
In general, conventional DEA is deficient in the discriminating power when there are a large number of criteria. The two-level DEA is established in this thesis to enhance the discriminating power of the standard DEA. In the two-level DEA, the supplier selection criteria for the same aspect are grouped together and form the hierarchical structure composes of two levels. Thereby, the two-level DEA model is able to handle quite a large number of input and output criteria.
A case study has been conducted in the context of automobile industry to validate the feasibility and usefulness of the proposed methodology. The results indicate that the proposed methodology is able to screen out less qualified suppliers considering a comprehensive set of sustainability criteria.published_or_final_version

Full textAbstract:
Thesis (PhD)--Stellenbosch University, 2014.ENGLISH ABSTRACT: The policing and monitoring of South Africa's coastline and economic exclusion zone is made di cult not only by the size of the area of interest, but also by the limited resources available for maritime detection and policing. As a consequence, illegal activities, such as smuggling, poaching and illegal border crossings, are often conducted with impunity. Conventional approaches to monitoring coastal areas, such as the use of patrol boats, port inspections and aircraft surveillance, may be augmented by advances in technology that are steadily contributing vast amounts of data related to maritime activity. For example, various South African agencies collect auto- matic identi cation system and vessel monitoring system transmissions, and gather additional kinematic data of maritime vessels through a number of strategically placed coastal radars. A command and control centre for actively monitoring these data (outside of the intelligence community) was established by the South African Navy in 2014. Such centres provide surveillance operators with a real-time picture of a maritime region of interest from which they can identify relevant facts of interest through a reliance on experience and domain knowledge. The e ectiveness of this process may, however, be undermined by the vast quantities of data typically under consideration, by the di culty of identifying long-term trends in vessel kinematic behaviour and by the possibility of operator fatigue brought on by the relatively low incidence levels of activities of interest. E ective decision support tools may play a valuable role in this context by the automatic processing of these vast collections of data, by the identi cation of concepts of interest and by the prediction of future occurrences of interest. It is, however, essential that such tools should be exible enough to adapt to changes in typical vessel behaviour over time and that they should be capable of integrating new trends and new types of behaviours. Various approaches to maritime surveillance are investigated in this dissertation from the perspectives of threat detection and anomaly identi cation, with particular emphasis on a systems approach to decision support. A decision support system framework that utilises rule-based and data-driven mechanisms is proposed as a means to separate the interesting from the uninteresting and to provide early warnings of potentially threatening maritime vessel behaviour to operators. This system framework is primarily concerned with kinematic data and is restricted to the identi cation of certain types of activities. Successful classi cation and, ultimately, timely prediction of potentially threatening behaviour would allow for e ective policing by providing early warning to relevant entities, thus potentially leading to more e ective use of available policing resources.
AFRIKAANSE OPSOMMING: Die patrollering en monitering van die Suid-Afrikaanse kusgebied en gepaardgaande ekonomiese eksklusiewe zone word bemoeilik deur die grootte van die tersprake area en die beperkte hulpbronne wat vir patrollie-doeleindes aangewend kan word. Gevolglik gaan onwettige aktiwiteite, soos smokkelary, stroping en onwettige immigrasie dikwels ongestraf. Konvensionele benaderings tot die monitering van kusgebiede, soos die aanwending van patrolliebote, die uitvoer van hawe-inspeksies en gere elde lugpatrollies, kan aangevul word deur tegnologiese vooruitgang wat voortdurend tot groot hoeveelhede data oor maritieme aktiwiteit bydra. Verskeie Suid- Afrikaanse agentskappe ontvang byvoorbeeld outomatiese identi kasiestelsel en vaartuigmoni- teringstelsel uitsendings, en samel ook addisionele kinematiese data oor maritieme vaartuie deur middel van strategies-geplaasde kusradars in. 'n Bevel-en-beheersentrum wat hierdie inligting (buite die intelligensiegemeenskap) aktief ontleed, is in 2014 deur die Suid-Afrikaanse Vloot tot stand gebring. Sulke sentra verskaf 'n intydse blik oor die maritieme gebied onder beskouing aan operateurs wat dan, gebaseer op hulle ervaring en omgewingskennis, relevante inligting oor vaartuie kan a ei. Die doeltre ende uitvoering van hierdie proses kan egter ondermyn word deur die tipiese groot hoeveelhede data, die moeilikheidsgraad van die identi kasie van langtermyn tendense in die kinematiese gedrag van vaartuie om die kus en die moontlikheid van operateur-uitputting as gevolg van lang periodes van relatiewe oninteressante vaartuiggedrag. Doeltre ende besluitsteunhulpmiddels kan 'n waardevolle bydrae in hierdie konteks maak deur die ge-outomatiseerde prosessering van hierdie groot hoeveelhede data, die identi kasie van interessante vaartuiggedrag en die voorspelling van toekomstige relevante insidente. Dit is egter noodsaaklik dat sulke hulpmiddels buigsaam genoeg moet wees om te kan aanpas by veranderings in tipiese maritieme aktiwiteit oor tyd en dat nuwe tendense en tipes aktiwiteite geakkommodeer kan word. Verskeie benaderings tot maritieme oorsig word in hierdie proefskrif vanuit die perspektiewe van die bespeuring van bedreigings en die opsporing van vreemde verskynsels ondersoek, met 'n spesi eke fokus op 'n stelselbenadering tot besluitsteun. 'n Besluitsteun stelselraamwerk wat berus op re el-gebaseerde en data-aangedrewe meganismes word as 'n hulpmiddel voorgestel waarmee interessante maritieme gedrag van oninteressante gedrag onderskei kan word om sodoende 'n vroe e waarskuwing aan operateurs met betrekking tot moontlike bedreigende maritieme aktiwiteite te kan rig. Die werking van hierdie stelselraamwerk berus hoofsaaklik op die gebruik van kinematiese vaartuigdata en is beperk tot die naspeuring van sekere soorte bedreigende gedrag. Die suksesvolle klassi kasie en tydige voorspelling van potensi ele bedreigende maritieme gedrag behoort doeltre ende kusmonitering en verbeterde aanwending van die beperkte, gepaardgaande hulpbronne deur relevante kusagentskappe moontlik te maak.

Full textAbstract:
As the global demand for energy continues to rise, the oil and gas industry investigates new opportunities for oil and gas production in more remote areas. Promising estimation of oil and gas reserves in the Arctic areas has resulted in an increased focus on oil extraction in the Higher Norths. For the logistic providers and ship yards, this area represent a new era in offshore operations and vessel design. The Arctic area offers challenges to offshore vessels but also to the offshore operation itself. Increased distances to shore and harsh environmental conditions sets new demands to the offshore supply chain. Platform supply vessels(PSVs) are an important part of the offshore logistic supply chain, providing offshore installations with necessary cargo and personnel. Accurate delivery is of high importance in order to ensure continuously production. Weather or not an offshore operation can be conducted, is restricted by environmental conditions at site. Exceedance of these limitations will affect the feasibility and duration of a voyage. In such cases, an oil operator may be forced to hire a vessel from the spot-marked. Although, offshore field logistics represent an important segment in offshore operations, the literature is scarce on the business side.It is clear that the current situation require new technological solutions, but also new and improved business models to ensure sustainability. In this paper we address the impact of the Arctic environment on PSVs.It has been investigated if a simulation model could be used to determine the operational duration and optimal fleet composition of PSVs in the Arctic environment. To determine the capability of the model, two case studies were presented.

Full textAbstract:
This research provides insights into project deliveries in the Barents Region. The aim of this research is to describe the project delivery process and to examine the barriers and the opportunities of transport logistics that are involved in project logistics in the Barents Region.
The research is conducted with qualitative research methods and it features two case examples of project deliveries. The literature review provides academic findings from transport logistics and project logistics sources. Theoretical framework is constructed of the project delivery process that encompasses a focus on barriers and opportunities of transport logistics. The data collection includes 8 interviews and observation.
The project delivery process consists of several phases: manufacturing, project cargo, transport mode choice, loading/stowing, transportation and final destination. This research provides also essential information of barriers and opportunities that are involved in project deliveries in the Barents Region. The project delivery process includes barriers that are: infrastructure, border crossing issues, distance, regulation and challenges with all-year traffic. According to the research findings, the best opportunities for project deliveries are road- and maritime transport. This research reveals that there are also difficulties in cross-border logistics between the Nordic countries, unlike the earlier academic findings suggest.
Clearly, this research provides both theoretical contribution and managerial implications. Earlier research of project deliveries is almost completely lacking, which means that new academic research is needed. Thus this research presents valuable and new theoretical contribution by describing and picturing the project delivery process in detailed fashion. The managerial implications are related to the findings of potential barriers and the best transport mode opportunities in project deliveries in the Barents Region. By clarifying the potential challenges of project deliveries, this research gives valuable information of what kinds of problems there might be, and most importantly this research gives instructions that are valuable for tackling those challenges. All in all, this research provides valuable findings of project logistics and cross-border logistics in the Barents Region.

Die Digitalisierung der Wirtschaft macht das Customer Targeting zu einer wichtigen Schnittmenge von Marketing und Wirtschaftsinformatik. Marketingtreibende können auf Basis von soziodemografischen und Verhaltensdaten gezielt einzelne Kunden mit personalisierten Botschaften ansprechen.
Diese Arbeit erweitert die Perspektive der Forschung im Bereich der modellbasierten Vorhersage von Kundenverhalten durch 1) die Entwicklung und Validierung neuer Methoden des maschinellen Lernens, die explizit darauf ausgelegt sind, die Profitabilität des Customer Targeting im Direktmarketing und im Kundenbindungsmanagement zu optimieren, und 2) die Untersuchung der Datenerfassung mit Ziel des Customer Targeting aus Unternehmens- und Kundensicht.
Die Arbeit entwickelt Methoden welche den vollen Umfang von E-Commerce-Daten nutzbar machen und die Rahmenbedingungen der Marketingentscheidung während der Modellbildung berücksichtigen. Die zugrundeliegenden Modelle des maschinellen Lernens skalieren auf hochdimensionale Kundendaten und ermöglichen die Anwendung in der Praxis. Die vorgeschlagenen Methoden basieren zudem auf dem Verständnis des Customer Targeting als einem Problem der Identifikation von Kausalzusammenhängen. Die Modellschätzung sind für die Umsetzung profitoptimierter Zielkampagnen unter komplexen Kostenstrukturen ausgelegt.
Die Arbeit adressiert weiterhin die Quantifizierung des Einsparpotenzials effizienter Versuchsplanung bei der Datensammlung und der monetären Kosten der Umsetzung des Prinzips der Datensparsamkeit. Eine Analyse der Datensammlungspraktiken im E-Mail-Direktmarketing zeigt zudem, dass eine Überwachung des Leseverhaltens in der Marketingkommunikation von E-Commerce-Unternehmen ohne explizite Kundenzustimmung weit verbreitet ist. Diese Erkenntnis bildet die Grundlage für ein auf maschinellem Lernen basierendes System zur Erkennung und Löschung von Tracking-Elementen in E-Mails.The digitization of the economy has fundamentally changed the way in which companies interact with customers and made customer targeting a key intersection of marketing and information systems. Building models of customer behavior at scale requires development of tools at the intersection of data management and statistical knowledge discovery. This dissertation widens the scope of research on predictive modeling by focusing on the intersections of model building with data collection and decision support. Its goals are 1) to develop and validate new machine learning methods explicitly designed to optimize customer targeting decisions in direct marketing and customer retention management and 2) to study the implications of data collection for customer targeting from the perspective of the company and its customers. First, the thesis proposes methods that utilize the richness of e-commerce data, reduce the cost of data collection through efficient experiment design and address the targeting decision setting during model building. The underlying state-of-the-art machine learning models scale to high-dimensional customer data and can be conveniently applied by practitioners. These models further address the problem of causal inference that arises when the causal attribution of customer behavior to a marketing incentive is difficult. Marketers can directly apply the model estimates to identify profitable targeting policies under complex cost structures. Second, the thesis quantifies the savings potential of efficient experiment design and the monetary cost of an internal principle of data privacy. An analysis of data collection practices in direct marketing emails reveals the ubiquity of tracking mechanisms without user consent in e-commerce communication. These results form the basis for a machine-learning-based system for the detection and deletion of tracking elements from emails.

Full textAbstract:
This thesis presents a decision support system, MAINTAIN, that was developed to assist maintenance and logistics planners in the evaluation of alternative strategies that might be used in the maintenance of a finite population of end items. The modeled population must consist of a finite number of identical end items, each at age zero at the beginning of the analysis. End items are modeled at their component level, with the lifetime of each component described by a probability distribution. These components are assumed to fail independently of each other and to cause end item failure if any one component should fail. Several component-level preventive maintenance policies are integrated into the modeling system and include age-based replacement, opportunistic lookahead replacement, or no replacement until failure.
Also incorporated into the model is the use of two repair facilities, which function as constraints on the resources available to perform maintenance tasks. One repair facility is used under normal conditions, while the second can be used when the first facility is operating beyond its capacity.
MAINTAIN is a simulation-based modeling system, in that a proposed or actual maintenance system is captured as an input data set and its operation is simulated over the specified planning horizon. Time-series output statistics are produced by the model to allow the analysis of time dependent parameters such as population availability, maintenance costs, spares requirements and repair facility utilization. Output data are available in several forms for use in external analyses.M.S.

Full textAbstract:
The logistics industry is known to be one of the main players for integrating Radio Frequency Identification (RFID) into their supply chain. By reflecting radio waves, RFID allows any item to become an intelligent part of an organization’s information infrastructure. RFID can create greater efficiency and effectiveness as it provides real-time information, and thus has the possibility to heavily increase logistics companies’ performance. RFID is also suggested to create marketing opportunities for companies as it facilitates customer value creation. However, little is known of RFID’s true influence on marketing. To fully understand what influence RFID has on marketing, companies must seek insight into what influence RFID has on the four P’s; Product, Price, Place and Promotion. By understanding this, companies can gain an increased knowledge of how to utilize RFID to increase their customer value and hence increase their competitive advantage in the targeted market. This study investigates what perceived influence RFID has on the four P’s within the logistics industry in Scandinavia. This was achieved by performing an exploratory research, and both primary and secondary data was collected in order ensure the validity and reliability of the study. The primary data was gathered by conducting in-depth interviews together with eight logistics companies located in Scandinavia. The findings from the interviews conducted suggested that the perception of RFID’s influence on the logistics industry’s offered product is positive. According to the findings, the use of RFID technology improved the logistic solution offered which also resulted in an increased perceived customer value. The findings also show that RFID has a positive perceived influence on price as well as promotion and place. In conclusion, the authors suggest that for RFID to have positive influence on the four P’s it must not only be successfully implemented into the logistics process, but it also requires the implementing company to reach a certain economy of scale, as well as hold a certain level of expertise about the technology to see the full potential of RFID. If these criteria are met there are several benefits to gain from use of RFID in marketing purposes in the logistics industry.

Full textAbstract:
The manufacturing strategy literature is reviewed and it is found to centre on content and process models. However, a number of other issues are present in the literature whose relationship to the central process and content models is less clear. These include the trade-off, focus, flexibility, and generic manufacturing strategies. It is noted that the manufacturing strategy literature does not fully address product customisation. The literature relating to the interface between marketing and manufacturing is found to concentrate either on the identification of conflict areas, or on strategic reconciliation between the functions. Writers in this field do give greater emphasis to product customisation. A case-study method is adopted for the research and the design involves four firms in varying industries. The firms manufacture fork-lift trucks, microswitches, telephone switching systems and diaries, respectively. The case-studies comprise quantitative and qualitative data, and each case chapter includes case-specific analysis. The analysis of all the cases finds that customisation has a very important effect on manufacturing performance. The firms have inconsistencies within their manufacturing strategies, but these are found to rest not only on the firms' manufacturing products with different volume requirements in the same plant, but also on the fact of some of the products being custom-designed. The interface between marketing and manufacturing is found to be more complex and variable than the literature would suggest. The role that customised products play in relationships with customers also varies, although this is inconsistently recognised by the firms.Based on the case-data, a model of product customisation is proposed. This incorporates customisation, flexibility, product architecture, the manufacturing strategy trade-off and the competitive criteria.

Thesis (MSc)--Stellenbosch University, 2011.ENGLISH ABSTRACT: As the world-wide consumption of electricity continually increases, more and more pressure is put on the capabilities of power generating systems to maintain their levels of power provision. The electricity utility companies operating these power systems are faced with numerous challenges with respect to ensuring reliable electricity supply at cost-e ective rates. One of these challenges concerns the planned preventative maintenance of a utility's power generating units. The generator maintenance scheduling (GMS) problem refers to the problem of nding a schedule for the planned maintenance outages of generating units in a power system (i.e. determining a list of dates corresponding to the times when every unit is to be shut down so as to undergo maintenance). This is typically a large combinatorial optimisation problem, subjected to a number of power system constraints, and is usually difficult to solve. A mixed-integer programming model is presented for the GMS problem, incorporating constraints on maintenance windows, the meeting of load demand together with a safety margin, the availability of maintenance crew and general exclusion constraints. The GMS problem is modelled by adopting a reliability optimality criterion, the goal of which is to level the reserve capacity. Three objective functions are presented which may achieve this reliability goal; these objective functions are respectively quadratic, nonlinear and linear in nature. Three GMS benchmark test systems (of which one is newly created) are modelled accordingly, but prove to be too time consuming to solve exactly by means of an o -the-shelf software package. Therefore, a metaheuristic solution approach (a simulated annealing (SA) algorithm) is used to solve the GMS problem approximately. A new ejection chain neighbourhood move operator in the context of GMS is introduced into the SA algorithm, along with a local search heuristic addition to the algorithm, which results in hybridisations of the SA algorithm. Extensive experiments are performed on di erent cooling schedules within the SA algorithm, on the classical and ejection chain neighbourhood move operators, and on the modi cations to the SA algorithm by the introduction of the local search heuristic. Conclusions are drawn with respect to the e ectiveness of each variation on the SA algorithm. The best solutions obtained during the experiments for each benchmark test case are reported. It is found that the SA algorithm, with ejection chain neighbourhood move operator and a local search heuristic hybridisation, achieves very good solutions to all instances of the GMS problem. The hybridised simulated annealing algorithm is implemented in a computerised decision support system (DSS), which is capable of solving any GMS problem instance conforming to the general formulation described above. The DSS is found to determine good maintenance schedules when utilised to solve a realistic case study within the context of the South African power system. A best schedule attaining an objective function value within 6% of a theoretical lowerbound, is thus produced.
AFRIKAANSE OPSOMMING: Met die wêreldwye elektrisiteitsverbruik wat voortdurend aan die toeneem is, word daar al hoe meer druk geplaas op die vermoë van kragstelsels om aan kragvoorsieningsaanvraag te voldoen. Nutsmaatskappye wat elektrisiteit opwek, word deur talle uitdagings met betrekking tot betroubare elektrisiteitsverskaffing teen koste-e ektiewe tariewe in die gesig gestaar. Een van hierdie uitdagings het te make met die beplande, voorkomende instandhouding van 'n nutsmaatskappy se kragopwekkingseenhede. Die generator-instandhoudingskeduleringsprobleem (GISP) verwys na die probleem waarin 'n skedule vir die beplande instandhouding van kragopwekkingseenhede binne 'n kragstelsel gevind moet word ('n lys van datums moet tipies gevind word wat ooreenstem met die tye wanneer elke kragopwekkingseenheid afgeskakel moet word om instandhoudingswerk te ondergaan). Hierdie probleem is tipies 'n groot kombinatoriese optimeringsprobleem, onderworpe aan 'n aantal beperkings van die kragstelsel, en is gewoonlik moeilik om op te los. 'n Gemengde, heeltallige programmeringsmodel vir die GISP word geformuleer. Die beperkings waaruit die formulering bestaan, sluit in: venstertydperke vir instandhouding, bevrediging van die vraag na elektrisiteit tesame met 'n veiligheidsgrens, die beskikbaarheid van instandhoudingspersoneel en algemene uitsluitingsbeperkings. Die GISP-model neem as optimaliteitskriterium betroubaarheid en het ten doel om die reserwekrag wat gedurende elke tydperk beskikbaar is, gelyk te maak. Drie doelfunksies word gebruik om laasgenoemde doel te bereik (naamlik doelfunksies wat onderskeidelik kwadraties, nie-lineêr en lineêr van aard is). Drie GISP-maatstaftoetsstelsels (waarvan een nuut geskep is) is dienooreenkomstig gemodelleer, maar dit blyk uit die oplossingstye dat daar onprakties lank gewag sal moet word om eksakte oplossings deur middel van kommersiële programmatuur vir hierdie stelsels te kry. Gevolglik word 'n metaheuristiese oplossingsbenadering ('n gesimuleerde temperingsalgoritme (GTA)) gevolg om die GISP benaderd op te los. 'n Nuwe uitwerpingsketting-skuifoperator word in die konteks van GISP in die GTA gebruik. Verder word 'n lokale soekheuristiek met die GTA vermeng om 'n basteralgoritme te vorm. Uitgebreide eksperimente word uitgevoer op verskeie afkoelskedules binne die GTA, op die klassieke en uitwerpingsketting-skuifoperators en op die verbasterings van die GTA meegebring deur die lokale soekheuristiek. Gevolgtrekkings word oor elke variasie van die GTA se e ektiwiteit gemaak. Die beste oplossings vir elke toetsstelsel wat gedurende die eksperimente verkry is, word gerapporteer. Daar word bevind dat die GTA met uitwerpingsketting-skuifoperator en lokale soekheuristiek-verbastering baie goeie oplossings vir die GISP lewer. Die verbasterde GTA word in 'n gerekenariseerde besluitsteunstelsel (BSS) geïmplementeer wat 'n gebruiker in staat stel om enige GISP van die vorm soos in die wiskundige programmeringsmodel hierbo beskryf, op te los. Daar word bevind dat die BSS goeie skedules lewer wanneer dit gebruik word om 'n realistiese gevallestudie binne die konteks van die Suid-Afrikaanse kragstelsel, op te los. 'n Beste skedule met 'n doelfunksiewaarde wat binne 6% vanaf 'n teoretiese ondergrens is, word ondermeer bepaal.

Full textAbstract:
The application of innovative methods to diminish the amount of human creation called “waste” should be applied not only under commercial terms, but also under the humanitarian concept. Negative results of focusing only on the fastest relief of human suffer without attending the consequences of the flow of items left on the disaster zones, could bring in the medium term, critical environmental consequences, due to the creation of new waste. This research analyzes relevant approaches of the Humanitarian Relief of Aid under a Humanitarian Logistics point of view. It aims to find if those approaches have already a Reverse Logistic phase of the items provided by donors. The results demonstrate the absence of a Reverse Logistics Phase for items brought to disaster zones. Thus, some proposals were suggested for a new Reverse Logistic Phase in any humanitarian relief of aid. NGOs, donors participation, coordination among players on the scene, managing inventories, last mile distribution, performance measurement, relief of aid models, and reverse logistics concepts applied to the humanitarian field would be only some of the themes revised on this research. These aim to enrich the readers’ knowledge on the topic as well as to provide an open panorama of the humanitarian actions employed in each Natural Disaster. The reader would acquire sufficient understanding to determine how feasible and reachable are the alternatives proposed by the authors. The relevance of this theme reveals a critical and not yet researched niche in Reverse Logistics under Humanitarian Logistics. It encourages more readers to research on it, explore and apply in future natural disasters. This research used a qualitative approach employing a semi-structured interview made to small and large humanitarian organizations.

Full textAbstract:
Thesis (MSc (Logistics))--University of Stellenbosch, 2009.ENGLISH ABSTRACT: Technological advances made over the past century have had a major impact on traditional wineries. Software solutions for management issues are widely available and give rise to the prospect of computerized decision support systems assisting in various aspects of managing a winery. The most popular applications seem to be concerned with supply chain management or harvest scheduling. Such projects are under way all over the globe and great success has been achieved to this e ect. However, prior to this study no such project has been considered in South Africa. The phrase active cellar scheduling problem refers to the assignment of grape batches to processors inside the cellar where bottlenecks often occur during the busy harvesting period. The phrase harvest scheduling problem, on the other hand, refers to selecting the best possible dates to harvest the respective vineyard blocks in order to preserve grape quality. A mixed integer programming model for the active cellar scheduling problem is derived in this thesis, but proves to be too time consuming to solve exactly via the branch-and-bound method. A meta-heuristic tabu search approach is therefore designed to solve the problem approximately instead. When applied to a small, ctitious cellar, it is found that the tabu search method often solves the problem optimally. The computer processing time associated with the tabu search approach also constitutes a signi cant (often thousand-fold) improvement over that of the branch-and-bound approach for realistically sized problem instances. A generic tabu search is also designed to solve the over-arching harvest scheduling problem for a general winery. This schedule is found by referring to the smaller tabu search of the active cellar scheduling in order to verify the impact that harvesting moves have on activities in the cellar. One harvesting schedule is considered a better schedule than another when it has a lower harvest evaluation score, determined by the placement of the vineyard blocks in the harvesting schedule. The harvest evaluation score takes into account the combination of vineyard blocks selected for harvesting on the same day (and their e ect on the active cellar) as well as the ripeness and quality of the grapes. Both tabu searches are nally included in a exible, computerized decision support system, called VinDSS. This system is found to produce good harvesting schedules when compared to an actual ve day schedule during the 2009 harvesting period at Wamakersvallei, a winery serving as case study for this thesis.
AFRIKAANSE OPSOMMING: Tegnologiese vooruitgang oor die afgelope eeu het 'n groot invloed op tradisionele wynkelders gehad. Sagteware-oplossings wat besluitsteun tot bestuursaangeleenthede bied, is algemeen beskikbaar en het gelei tot die rekenaarmatige implementering van besluitsteunstelsels vir wynkelders. Dit blyk dat die mees popul^ere besluitsteuntoepassings in die wynindustrie te make het met besluite rakende van voorsieningskettings en oes-skedulering. Sulke besluitsteunprojekte is w^ereldwyd onderweg en het alreeds groot sukses behaal. Daar is egter tot dusver geen so 'n projek in Suid-Afrika onderneem nie. Die frase aktiewe kelderskeduleringsprobleem verwys na die toekenning van druifvragte aan masjiene binne die kelder waar bottelnekke algemeen tydens die besige parstydperk voorkom. Die frase oes-skeduleringsprobleem, daarenteen, verwys na die seleksie van bes moontlike oesdatums vir elk van die wingerdblokke om sodoende druifkwaliteit te verseker. 'n Gemengde heeltallige programmeringsmodel is vir die aktiewe kelderskeduleringsprobleem ontwikkel, maar die rekenaaroplossingstyd van hierdie benadering blyk te lank te wees om die probleem eksak deur middel van 'n vertak-en-begrens metode op te los. 'n Meta-heuristiese tabu soektog is dus ontwikkel om die probleem benaderd op te los. Wanneer hierdie benadering op 'n klein, ktiewe kelder toegepas word, word optimale oplossings dikwels verkry. Verder toon die rekenaaroplossingstyd van die tabu soektog 'n groot (in sommige gevalle byna 'n duisendvoudige) verbetering op di e van die eksakte oplossingsmetode. 'n Generiese tabu soektog is ook ontwikkel om die oorkoepelende oes-skeduleringsprobleem vir 'n algemene wynkelder op te los. So 'n oes-skedule word gevind deur na die kleiner tabu soektog vir die aktiewe kelderskedulering te verwys om sodoende die e ekte van veranderinge in die oesskedule op die prosesse binne die aktiewe kelder na te speur. Een oes-skedule word beter as 'n ander skedule beskou wanneer dit met 'n beter oes-evalueringswaarde gepaard gaan, soos deur die plasing van die wingerdblokke in die skedule bepaal. Die oes-evalueringswaarde neem die moontlike kombinasies van wingerblokke wat op dieselfde dag geoes word, in ag (en ook die e ek wat dit op aktiwiteite in die kelder het), asook die rypheid en kwaliteit van die druiwe. Beide tabu soektogte word in 'n plooibare, rekenaar-ge mplementeerde besluitsteunstelsel, bekend as VinDSS, ingesluit. Daar word gevind dat hierdie stelsel goeie oes-skedules lewer wanneer dit vergelyk word met 'n werklike vyf-dag skedule tydens die 2009 parsseisoen van Wamakersvallei, die kelder wat as gevallestudie vir hierdie tesis gedien het.

Full textAbstract:
La logística urbana intel·ligent constitueix un factor crucial en la creació de sistemes de transport urbà eficients i sostenibles. Entre altres factors, aquests sistemes es centren en la incorporació de dades en temps real i en la creació de models de negoci col·laboratius en el transport urbà de mercaderies, considerant l’augment dels habitants en les ciutats, la creixent complexitat de les demandes dels clients i els mercats altament competitius. Això permet als que planifiquen el transport minimitzar els costos monetaris i ambientals del transport de mercaderies a les àrees metropolitanes. Molts problemes de presa de decisions en aquest context es poden formular com a problemes d’optimació combinatòria. Tot i que hi ha diferents enfocaments de resolució exacta per a trobar solucions òptimes a aquests problemes, la seva complexitat i grandària, a més de la necessitat de prendre decisions instantànies pel que fa a l’encaminament de vehicles, la programació o la situació d’instal·lacions, fa que aquestes metodologies no s’apliquin a la pràctica. A causa de la seva capacitat per a trobar solucions pseudoòptimes en gairebé temps real, els algorismes metaheurístics reben una atenció creixent dels investigadors i professionals com a alternatives eficients i fiables per a resoldre nombrosos problemes d’optimació en la creació de la logística de les ciutats intel·ligents. Malgrat el seu èxit, les tècniques metaheurístiques tradicionals no representen plenament la complexitat dels sistemes més realistes. En assumir entrades (inputs) i restriccions de problemes deterministes, la incertesa i el dinamisme experimentats en els escenaris de transport urbà queden sense explicar. Els algorismes simheurístics persegueixen superar aquests inconvenients mitjançant la integració de qualsevol tipus de simulació en processos metaheurístics per a explicar la incertesa inherent a la majoria de les aplicacions de la vida real. Aquesta tesi defineix i investiga l’ús d’algorismes simheurístics com el mètode més adequat per a resoldre problemes d’optimació derivats de la logística de les ciutats. Alguns algorismes simheurístics s’apliquen a una sèrie de problemes complexos, com la recollida de residus urbans, els problemes de disseny de la cadena de subministrament integrada i els models de transport innovadors relacionats amb la col·laboració horitzontal entre els socis de la cadena de subministrament. A més de les discussions metodològiques i la comparació d’algorismes desenvolupats amb els referents de la bibliografia acadèmica, es mostra l’aplicabilitat i l’eficiència dels algorismes simheurístics en diferents casos de gran escala.Las actividades de logística en ciudades inteligentes constituyen un factor crucial en la creación de sistemas de transporte urbano eficientes y sostenibles. Entre otros factores, estos sistemas se centran en la incorporación de datos en tiempo real y la creación de modelos empresariales colaborativos en el transporte urbano de mercancías, al tiempo que consideran el aumento del número de habitantes en las ciudades, la creciente complejidad de las demandas de los clientes y los mercados altamente competitivos. Esto permite minimizar los costes monetarios y ambientales del transporte de mercancías en las áreas metropolitanas. Muchos de los problemas de toma de decisiones en este contexto se pueden formular como problemas de optimización combinatoria. Si bien existen diferentes enfoques de resolución exacta para encontrar soluciones óptimas a tales problemas, su complejidad y tamaño, además de la necesidad de tomar decisiones instantáneas con respecto al enrutamiento, la programación o la ubicación de las instalaciones, hacen que dichas metodologías sean inaplicables en la práctica. Debido a su capacidad para encontrar soluciones pseudoóptimas casi en tiempo real, los algoritmos metaheurísticos reciben cada vez más atención por parte de investigadores y profesionales como alternativas eficientes y fiables para resolver numerosos problemas de optimización en la creación de la logística de ciudades inteligentes. A pesar de su éxito, las técnicas metaheurísticas tradicionales no representan completamente la complejidad de los sistemas más realistas. Al asumir insumos y restricciones de problemas deterministas, se ignora la incertidumbre y el dinamismo experimentados en los escenarios de transporte urbano. Los algoritmos simheurísticos persiguen superar estos inconvenientes integrando cualquier tipo de simulación en procesos metaheurísticos con el fin de considerar la incertidumbre inherente en la mayoría de las aplicaciones de la vida real. Esta tesis define e investiga el uso de algoritmos simheurísticos como método adecuado para resolver problemas de optimización que surgen en la logística de ciudades inteligentes. Se aplican algoritmos simheurísticos a una variedad de problemas complejos, incluyendo la recolección de residuos urbanos, problemas de diseño de la cadena de suministro integrada y modelos de transporte innovadores relacionados con la colaboración horizontal entre los socios de la cadena de suministro. Además de las discusiones metodológicas y la comparación de los algoritmos desarrollados con los de referencia de la bibliografía académica, se muestra la aplicabilidad y la eficiencia de los algoritmos simheurísticos en diferentes estudios de casos a gran escala.
Smart city logistics are a crucial factor in the creation of efficient and sustainable urban transportation systems. Among other factors, they focus on incorporating real-time data and creating collaborative business models in urban freight transportation concepts, whilst also considering rising urban population numbers, increasingly complex customer demands, and highly competitive markets. This allows transportation planners to minimize the monetary and environmental costs of freight transportation in metropolitan areas. Many decision-making problems faced in this context can be formulated as combinatorial optimization problems. While different exact solving approaches exist to find optimal solutions to such problems, their complexity and size, in addition to the need for instantaneous decision-making regarding vehicle routing, scheduling, or facility location, make such methodologies inapplicable in practice. Due to their ability to find pseudo-optimal solutions in almost real time, metaheuristic algorithms have received increasing attention from researchers and practitioners as efficient and reliable alternatives in solving numerous optimization problems in the creation of smart city logistics. Despite their success, traditional metaheuristic techniques fail to fully represent the complexity of most realistic systems. By assuming deterministic problem inputs and constraints, the uncertainty and dynamism experienced in urban transportation scenarios are left unaccounted for. Simheuristic frameworks try to overcome these drawbacks by integrating any type of simulation into metaheuristic-driven processes to account for the inherent uncertainty in most real-life applications. This thesis defines and investigates the use of simheuristics as a method of first resort for solving optimization problems arising in smart city logistics concepts. Simheuristic algorithms are applied to a range of complex problem settings including urban waste collection, integrated supply chain design, and innovative transportation models related to horizontal collaboration among supply chain partners. In addition to methodological discussions and the comparison of developed algorithms to state-of-the-art benchmarks found in the academic literature, the applicability and efficiency of simheuristic frameworks in different large-scaled case studies are shown.
