Full textAbstract:
A disruption to the supply of input materials is one of the main threats to manufacturing supply chains. Trade wars, natural disasters, pandemics, cyber-attacks, sudden changes in cost and quality, machine breakdowns and transport accidents are among the causes of disruptions to supply chains. The supply chain is made up of several interconnected parties, where a product or service moves from raw material suppliers through to manufacturing, before its final delivery to customers. The extent and complexity of such interconnections can significantly increase the vulnerability of the supply chain system to disruptions. A disturbance to one party may propagate to other nodes and cause major disruption and financial losses for the whole supply chain.
Many causes of supply disruptions are beyond the control of supply chain managers, therefore the best way to manage them is to be proactive. Supply chain managers undertake a risk management process to prepare the supply chain for mitigating the possible impacts of disruptions. Managers have several options to control their exposure to disruption risks. Two main options available are stocking material in inventory and maintaining a portfolio of suppliers.
This thesis focuses on managing supply disruption risks in supply chains. It aims to assist the supply chain managers to mitigate the risk of supply disruptions and the corresponding effects these will have on profits. This thesis makes its contribution in three broad steps:
(1) Development of a decision-making model to efficiently mitigate the likelihood of a supply disruption. The model determines an optimal supplier portfolio through continuous monitoring of supply risk indicators that detects early warnings of a supply disruption. Risk indicators are based on a supplier’s product price, financial and production stability, and quality. Using an integrated system dynamics and portfolio optimisation solution approach, the model assists decision-makers to rebalance their supplier portfolio in response to early changes in supply risk indicators over a planning horizon.
(2) Development of an optimal inventory strategy model from the perspective of a manufacturer in a supply chain. This model aims to determine the optimal inventory strategy based on the expected supply price and product market demand over a planning horizon. The model seeks to maximise the manufacturer’s profit at the beginning of a planning horizon, rendering the inventory option as managerial flexibility to mitigate the undesirable effects of supply disruptions.
(3) Development of a decision-making model to determine an optimal contracting strategy, sourcing policy and inventory management at each period to maximise the manufacturer’s profit at the beginning of the planning horizon. This third step allows for the concurrent application of managerial flexibilities to manage supply chain risks. This model adopts the view of a manufacturer in a supply chain with two suppliers. It provides the manufacturer with the optimal allocation of supplies, including an optimal long-term contract position with one supplier at the beginning of the planning horizon. The model also enables the decision-makers to find the optimal inventory strategy at each period to mitigate the effects of supply disruptions and maximise profit for the manufacturer.
To develop the decision-making models in steps (2) and (3), this thesis applies a real options analysis method. An American-style option valuation method is used to solve the optimal inventory, sourcing and contracting strategy under uncertain supply price and product demand. This thesis uses a least-square Monte Carlo simulation to solve the underlying dynamic programming model.
The results of the modelling in step (1) demonstrate how a supply portfolio can be developed to provide higher expected profit at a certain level of risk. They also show how the optimal decision depends on the risk propensity of the decision-maker. The results of modelling in step (2) demonstrate the conditions under which inventory flexibility is valuable to a supply chain. Results show how a higher expected supply price during a disruption period and a higher expectation of disruption, increases the value of an inventory flexibility option. Expectations of early disruptions increased the value of the inventory option. Results of modelling in step (3) show how a manufacturer can balance their inventory of supplies and a long-term contract with one supplier at the beginning of the planning horizon to maximise profit.

Full textAbstract:
Includes bibliography.Uninterruptible power supplies (UPS) maintain a constant supply of power to a critical load. The distinguishing features are a fixed voltage and frequency, low harmonic content and the ability to supply the load for a period of time after the incoming supply has failed. The document begins by identifying the typical power-line disturbances and their effect on various types of equipment. Together with the power conditioners used to suppress these disturbances, various UPS standby, line-interactive and on-line configurations are introduced. Next, the possibility of modifying a locally manufactured UPS to meet the design specifications is investigated. The performance of the system under load is evaluated, and forms the basis for the following decision. Due to the large number of modifications required and the inflexibility of local UPS topology, an alternative topology is adopted. In the new topology a power factor corrector, constructed around a DC to DC boost converter, interfaces with the incoming AC line. It delivers a half sinusoidal current into the DC bus. An IGBT inverter using sinusoidal unipolar pulse-width modulation regenerates the AC load voltage after filtering through a LC-filter. The DC bus voltage ripple is reduced by synchronising the inverter load and power factor corrector current while the battery pack maintains the DC bus during a power failure. The power factor corrector employs a dedicated analogue controller chip while a MCS-51 microcontroller generates the inverter PWM, provides the remote monitoring facilities, battery charging and performs general support tasks. The total harmonic distortion of the input current is measured at less than 4% while the power factor remained above 0.99 over the entire load range. The ripple regulator reduced the DC bus voltage ripple without any noticeable effect on the load. Under maximum load, the steady state output voltage is maintained during the -20%, +10% variation in the incoming line voltage. However, the transient response fails to meet the 5% design specification. A 0-100% load step results in a 7% drop in the output voltage while the loss of the load results 10% jump in voltage. System efficiency is measured at 85%. It is the lack of processing power, precluding the use of floating point or an optimal control algorithm, which ultimately compromises the performance of the system. It is recommended that the microcontroller be replaced with a 16-bit processor or digital signal processor to provide the extra computational power needed to optimise the UPS response. To improve the voltage regulation, it is recommended that the control include an inner current loop while the switching frequency should be increased to reduce the energy storage in the output filter. Further adjustments and refinements to the topology are suggested in the final chapter.

Research questions 1. What kind of risks in the supply side of HUAWEI supply chain can be identified? 2. How can supply side risks of HUAWEI supply chain be assessed? 3. How can supply side risks of HUAWEI supply chain be mitigated? Purpose This paper describes supply side risks in HUAWEI in China, the types of risks identified, provides guidelines for assessment of these risks and suggestions for mitigation. Methodology In order to answer above research questions empirical data have been collected through observations, interviews at with logistics managers of HUAWEI in China, and from the official documents, annual reports and authentic web pages of the HUAWEI. Theoretical framework has been built through scientific articles, peer reviewed journals, authentic web based documents, and textbooks. The information is then assessed and analyzed, which result in conclusion and recommendations for the company. Conclusion There can be four major risks identified on the supply side. Manufacturing risk, logistics risk, information risk and inventory risk. The manufacturing risk include risks related to production, skill, and quality. The logistics risk further include delivery risk, lead time risk, and transportation risk. Production risk and skill risk are critical and they can be avoided by enhancing risk awareness, evaluating production feasibility, strengthen staff training, investing in high skills, strengthening R&D, and analysis of the external environment. The quality and inbound delivery risks can be reduced through supplier inspection and establishing good supplier relations. Lead time risk and inventory risk can be reduced by vendor based managed inventory system and mass customization. Meanwhile, transportation risk can adopt risk transfer strategy. The information risk can be reduced by increasing information sharing levels and adopting modern communication technologies.

Full textAbstract:
This dissertation focuses on topics related to the value of real-time information and/or to supply uncertainties due to uncertain lead-times and yields in supply chains. The first two of these topics address issues associated with freight transportation, while the remaining two topics are concerned with inventory replenishment.
We first assess the value of dynamic tour determination for the traveling salesman problem (TSP). Given a network with traffic dynamics that can be modeled as a Markov chain, we present a policy determination procedure that optimally builds a tour dynamically. We then explore the potential for expected total travel cost reduction due to dynamic tour determination, relative to two a priori tour determination procedures.
Second, we consider the situation where the decision to continue or abort transporting perishable freight from an origin to a destination can be made at intermediate locations, based on real-time freight status monitoring. We model the problem as a partially observed Markov decision process (POMDP) and develop an efficient procedure for determining an optimal policy. We determine structural characteristics of an optimal policy and upper and lower bounds on the optimal reward function.
Third, we analyze a periodic review inventory control problem with lost sales and random yields and present conditions that guarantee the existence of an optimal policy having a so-called staircase structure. We make use of this structure to accelerate both value iteration and policy evaluation.
Lastly, we examine a model of inventory replenishment where both lead time and supply qualities are uncertain. We model this problem as an MDP and show that the weighted sum of inventory in transit and inventory at the destination is a sufficient statistic, assuming that random shrinkage can occur from the origin to the supply system or destination, shrinkage is deterministic within the supply system and from the supply system to the destination, and no shrinkage occurs once goods reach the destination.

Due to the global expansion of Company A's supply chain network, it is becoming more vulnerable to many disruptions. These disruptions often incur additional costs; and require time to respond to and recover from these disruptions. The base paper supply chain was identified as the most vulnerable area of the Company A Jurong and South & Southeast Asia Cluster supply chain; and a multi-stage supply chain was proposed to improve the supply chain's resilience. A statistical model was constructed to select the optimal location of the central warehouse for the proposed multi-stage supply chain. After evaluating the resilience to disruptions and the cost effectiveness of supply chains, the multi-stage supply chain with central warehouse in Tanjung Pelepas, Malaysia was found to be overall most resilient and cost effective among all the supply chains. It also incurs a lower additional cost in the event of a disruption such as changes in exchange rates and demand forecast accuracy, fuel price fluctuation, labor cost increase and shipping disruptions. As a result, establishing this multistage supply chain is recommended.

Full textAbstract:
This thesis deals with the effect of supply information sharing and updating on different areas of supply chain management including, inventory management, Marketing and behavioral management. It addresses how mathematical modeling can help managers who are concerns about supply uncertainty issues. Although in literature more attention is restricted to demand updating, models developed in this thesis contribute to learning effect on supply availability literature. First, from inventory management point of view, we model a two-product, periodic-review inventory problem in which the probability of supply availability is unknown and there are two different fixed cost assigned to each product. We investigate the effect of supply uncertainty forecasting with Bayesian updating on ordering policy and the behavior of the system. (s,S) policy along with two switching curves are proved to determine the optimal ordering policy. Our results indicates that improving the accuracy of the forecast leads to making a better ordering decision and eliminating the negative effect of supply disruption on the total cost. Second, we study channel coordination and yield risk forecast sharing for additive random yield in a three-level supply chain including a supplier, a manufacturer and a distributor. We investigate whether random yield forecasting is beneficial for the supply chain parties or not. If it is, under which condition and what contract the distributor shares the knowledge of supply risk with the retailer. Finally, we focus on the rule of trust in supply forecast signaling for a supply chain with a supplier and a manufacturer in a one-shot game. We determine the manufacturer’s optimal order quantity for two types of information sharing situation, truthful and untruthful. Moreover, different scenarios of information sharing are compared numerically.

This thesis explores the use of different approaches and structures to facilitate coordinating a set of strategic business partners across multiple tiers of a single supply chain - defined as the supply network. The study is based on a deductive model of three dimensions of coordination, corresponding to the information, material, and financial dependencies between organizations in a supply network. This segmentation allows separate exploration of coordination structures at the level of information systems, logistics and operations, and financial allocation across organizations within the supply network. The research methodology entailed the use of the Delphi technique, soliciting input via in-depth personal interviews from academic, industry, and consulting experts in supply chain management. This method is selected because of few current examples in industry, lack of hard data and absence of structured frameworks in the field. For each of the coordination dimensions, the structures and mechanisms to efficiently coordinate a supply network were identified, described, and categorized. The result is a structured spectrum of coordinating approaches that illustrates the managing of dependencies within the supply network. Trends and consensus in the responses are identified from the data to provide insight into future developments in the field. Illustrative examples of such coordination structures are discussed to demonstrate the inner working of coordinating mechanisms, and to identify the key issues, requirements and obstacles in achieving coordination across multiple tiers.

Full textAbstract:
This thesis studies the influence of horizontal competition on supply chain performance. Unlike most of the existing literature which focuses on horizontal competition between echelon levels, we look at both the supply chain and the individual company??s performance with the presence of supply chain to supply chain competition. Specifically, this thesis is composed of three individual research papers. The first paper deals with chain-to-chain horizontal competition and considers price competition among an arbitrary number of supply chains by comparing two cases. In the first case each supply chain is vertically integrated, while in the second, decentralised, case the manufacturers and retailers act independently. We explore the effect of varying the level of price competition on the profitts of the industry participants and demonstrate the important role played by the spread of underlying market shares. The coefficient of variation of these market shares determines whether decentralised supply chains can outperform integrated supply chains with an appropriate level of competition. The second and third papers focus on in-chain horizontal competition with capacity constraints. In the second paper, we look at a supply chain with one manufacturer and two downstream retailers. Based on total capacity available, the manufacturer needs to find ways to best use the capacity by determining whether or not to release the capacity information to retailers. The third paper looks at competition in a more complicated supply chain structure. A retailer buys three brands of products from two manufacturers. One manufacturer produces both branded and private label products, and the other one manufactures a branded product only. With our model, we are able to determine the profits of each supply chain agent. At the end of the paper, we use data from the Australian milk industry and discuss a problem in which a manufacturer needs to decide how to allocate capacity between the national brand and the private label when there is a capacity shortage.

The strong bargaining power of major retailers and the higher requirements for speed, service excellence and customization have significantly contributed to transform the Supply Chain Management. These increasing challenges call for an integrated and dynamic Supply Chain Management and for a better integration and alignment with key customers, in order to reduce the firm's time-to-market and build competitive advantage. The thesis aims at providing the partner company, a major player in the consumer goods industry, with a more robust and efficient vendor managed inventory practice, so that the partner can determine the optimum inventory level to satisfy turnover, service level and lead time requirements, whereas minimizing lost sales and total costs in the system. The team developed a Supply Chain Dynamics framework to help the partner to establish new service level strategies, strongly oriented to the strategic importance of its products and customers, and to map the key system-wide drivers that impact the overall number of inventory turns, service level and total costs. Additionally, in order to run simulations and estimate the outcomes of the proposed recommendations, the team developed a "Multi-Echelon" simulator and used a commercial "Supply Chain Dynamics" simulator.

In Europe, 45% of vegetables and fruit have been lost before consumption. The main reason for the loss is suboptimal food, which is perfect based on safety and security but imperfect according to appearance or packaging. In this project, I want to find out new possibilities in urban development by suggesting a participative food supply chain. It aims to inspire a paradigm of urban development and shift people’s attitudes towards suboptimal food. The participative supply chain includes food production, distribution, and retail/consumption. By participating in the food supply, residents and visitors can understand how the food system works, grow their food and help with food processing. With interaction and collaboration workers, they can value more about the food they consume and even change their eating patterns.

The Global Business Climate has been rapidly changing and has become more competitive. Enterprise now not only needs to operate at a lower cost to compete, it must also develop its own core competencies to distinguish itself from competitors and stand out in the market. The focus has now moved towards improving operational efficiency to stay competitive. Supply Chain is one of the important areas which almost every company is currently working to improve their operation efficiency. Improving operational efficiency in supply chain has three aspects including improving supply chain strategies, following better supply chain management practices, and aligning supply chain strategy with overall business strategy. Our thesis research objective is to understand what policies, capabilities, and strategies of an enterprises leads to best supply chain management. The research is cross industry, across all supply chain management domain and will shed light on what makes companies "best performer" by identifying and exploring the distinctive capabilities required in five key supply chain domains that contribute to high performance in the relevant operational metrics. The domains studied in our research are supply chain planning, fulfillment, service management, product lifecycle management, and, manufacturing. Another objective of our thesis is to relate domain performance of the firm with the firm's value proposition. The three value propositions considered in the thesis are product leadership/innovation, cost competitiveness, and customer service.

Full textAbstract:
Supply chain integration (SCI) is a phenomenon that has received growing attention from academia and industry practitioners alike. Studies suggest that firms with highly integrated supply chains can positively influence firm performance from both an operational and financial standpoint. The literature emphasizes three distinct dimensions of SCI; internal integration, supplier integration and customer integration. However, the scarcity of highly integrated supply chains could be widespread in South Africa due to the SCI perception gaps prevalent among supply chain practitioners in South Africa. The literature reveals that there are countless inconsistencies pertaining to the interpretation and execution of supply chain management practices among supply chain practitioners, across myriads of industries. This study aimed to investigate the various perceptions of the SCI construct harboured by supply chain practitioners in fast-moving consumer goods (FMCG) manufacturing firms. A generic qualitative research strategy was used as the method of inquiry in this research. Five FMCG manufacturing firms were sampled and a total of fifteen participants were
interviewed though semi-structured interviews. The main findings of the study reveal that supply chain practitioners in FMCG manufacturing firms interpret the SCI construct differently. While some supply chain practitioners interpret the SCI construct in line with what is documented in the literature, others have misaligned interpretations of the construct. These differences in interpretation span across all tiers (strategic, tactical and operational) within FMCG manufacturing firms. The findings also reveal that supply chain practitioners in South African FMCG manufacturing firms, to a significant extent, identify with all the supply chain integrative practices relating to supply chain collaboration, intra/inter firm interaction and information sharing, as documented in the literature. The study’s findings contribute to the supply chain discipline by helping researchers as well as supply chain practitioners develop a complete understanding of the SCI construct which deliberately elaborates on the associated SCI dimensions, and explicitly articulates the integrative practices associated with the phenomenon. Managerial implications emanating
from this study suggest that supply chain functions should strive to create awareness around the focal firm’s end-to-end supply chain activities, and how these activities impact each other. This can be done through building a culture of frequent inter- and intra- organisational interaction, as well as implementing relevant organisational learning interventions across all tiers within the focal firm. In addition, focal firms should also adopt and leverage off new technologies to ensure more reliable and real-time data, thus enabling more effective decision-making.Dissertation (MCom)--University of Pretoria, 2020.

Full textAbstract:
On March 2011 a destructive 9.0-magnitude earthquake and tsunami along with nuclear explosions struck northeastern Japan; killing thousands of people, halting industry and crippling infrastructure. A large manufacturing company operating outside of Japan received the news in the middle of the night. Within a few hours of the tsunami hitting Japan, this manufacturer’s logistics team ran global materials management reports to communicate the precise status of the products originating from Japan to their entire global network of facilities. With this quick and far reaching communication the manufacturer was able to launch a successful contingency plan. Alternative suppliers, already existing as part of their global network, were evaluated and used to mitigate Japan’s disruptive impact. The resiliency of this manufacturer’s trusted network of supply chain trading partners allowed for minimum disruptions, saving countless money and maintaining continuity for its end-to-end supply chain. This manufacturer was part of a cloud-based supply chain that provided the catalyst to quickly shift its resources to allay the impact of no longer being able to receive product from Japan. Today's supply chains are global and complex networks of enterprises that aim to deliver products in the right quantity, in the right place, and at the right time in an increasingly volatile and unpredictable environment. To cope with internal and external supply chain instability and disruptions, supply chains need to be resilient to survive. A supply chain's ability to collaboratively share information with its supply chain partners is one of the most important factors that enhance a supply chain’s resilience. Cloud based supply chain management (SCM) creates a platform that enables collaborative information sharing that helps to identify, monitor and reduce supply chain risks, vulnerabilities and disruptions. However, supply chain academics and practitioners are at its infancy in understanding the capabilities of cloud based supply chains and its impact on resiliency. The goal of this dissertation is to explore how cloud based SCM make supply chains more resilient to disruptions. To achieve this goal the present research addresses the following fundamental research question: What is the impact of cloud based supply chain management (SCM) on supply chain resilience? To address this research question, this dissertation is comprised of three separate but interrelated essays. The first essay uses the systematically literature review (SLR) method to provide clear definitions of supporting constructs of supply chain resiliency (SCRES), classify the capabilities of SCRES, and identify existing research gaps and future SCRES research ideas. The second essay applies resource-based view (RBV) and dynamic capabilities as the theoretical lens to investigate the role of cloud based SCM in establishing SCRES. The second essay develops a theory-driven, conceptual model to illustrate and explain the relationships among cloud based SCM, SCRES, and the supply chain capabilities identified in the first essay. The third essay uses systems dynamics theory to develop two novel casual loop diagrams (CLD) and its equivalent systems dynamics (SD) models to quantitatively analyze the impact of cloud based information sharing on supply chain performance. A hospital supply chain is used as an illustrative example to show the positive impact on performance. Lead-time, inventory spend, and customer service levels are the comparative performance metrics used in this essay and are consistent with the findings of essays 1 and 2. One CLD and its equivalent SD model represent a traditional on-premise hospital supply chain information sharing platform and the other represent a cloud based hospital information sharing platform. The SD models simulate and compare the performance of the traditional and cloud based hospital supply chain platforms.

In this study, existing work, opportunities, standards and essential safety aspects on development of LVDC distribution systems have been considered. It can be summarised that the standard requirements for AC systems also applies to DC systems, and that one does not come apart DC-DC regulators in equipment due to the galvanic separation which is needed to fulfil the safety requirements. One of the main challenges of introducing an LVDC system is the non-existence of building codes and standards intended for an LVDC system in buildings.The critical step of developing a DC distribution system is selecting the voltage level. Earlier studies conclude that:•A standard voltage level of 230 V DC is proven to be sufficient for normal office loads, as long as the cable length does not exceed 80 m•For higher power loads up to 6.5 kW the voltage level has to be increased to 326 V DC for systems with a cable length of maximum 47 m and 2.5 mm2This study proposes an LVDC system supplied by converted power from the main grid (AC-DC), where the size of the LVDC system is decided by performed measurements at an example building. In order to compare the losses in an AC and DC system, it was chosen to perform simulations on component level. It can be concluded that:•An LVDC system supplied by a central VSC converting power from the AC grid is an energy efficient system solution compared to the existing AC system solution, largely depending on the performance of the VSCSimulations and calculations resulted in a requirement of performance > 97.7 % of the VSC in order for it to be more energy efficient with an DC system instead of the existing AC system solution with AC-DC converters in each link with a performance of approximately 97 %. Experts believe that it is possible to gain this performance in the future based on performance for smaller converters developed by leading manufactures.Based on the different aspects considered regarding introduction of an LVDC distribution system, simulated models, and performed measurements, it can be concluded that:•From earlier studies it can be concluded that on the economic side, an LVDC distribution system seems benefitual•Original DC loads will benefit from having a separate DC system in terms of power loss at a voltage level of 230 V DC•AC loads require high power delivered and it will be most energy efficient to keep the connection to the existing AC system•An LVDC system with a size of approximate 20 kW is realistic in the future, supplying a floor in a building with DC loadsFrom the material presented in this report, it can be summarised that it is a realistic possibility for future distribution systems in buildings to have an energy efficient mixed supply system, AC and DC.

Due to the global expansion of Company A's supply chain network, it is becoming more vulnerable to many disruptions. These disruptions often incur additional costs; and require time to respond to and recover from these disruptions. The base paper supply chain was identified as the most vulnerable area of the Company A Jurong and South & Southeast Asia Cluster supply chain; and a multi-stage supply chain was proposed to improve the supply chain's resilience. A statistical model was constructed to select the optimal location of the central warehouse for the proposed multi-stage supply chain. After evaluating the resilience to disruptions and the cost effectiveness of supply chains, the multi-stage supply chain with central warehouse in Tanjung Pelepas, Malaysia was found to be overall most resilient and cost effective among all the supply chains. It also incurs a lower additional cost in the event of a disruption such as changes in exchange rates and demand forecast accuracy, fuel price fluctuation, labor cost increase and shipping disruptions. As a result, establishing this multistage supply chain is recommended.

Introduction: Supply chain management has been defined as, "..a set of approaches utilized to efficiently integrate suppliers, manufacturers, warehouses and stores, so that merchandise is produced and distributed at the right quantities, to the right locations and at the right time, in order to minimize system-wide costs.... satisfying service level requirements.. " -- ".. integration of activities ..through improved supply chain relationships to achieve sustainable competitive advantage.. " -- "..coordination and collaboration with channel partners.. coordination of process and activities.. " [53] "..from the ore mine to the trash can... the production and distribution network that encompasses the sourcing, manufacturing, transportation, commercialization, distribution, consumption, and disposal of goods.. " -- "...flow of requirement information from buyer to seller which triggers all later activities, the movement of goods from sellers to buyers, transfer of ownership rights from seller to buyer and payment from buyer to seller. " The above definitions offer a broad spectrum of supply chain orientation and management choices available to companies. They could vary from a transactional orientation that is focused on low cost acquisition; to one where stronger relationships are established with key suppliers and customers in an effort to optimize and capture synergies; onward to a partnership orientation that is focused on supporting mutual goals for a sustainable competitive advantage. Making the right choice is essential. It can have a significant impact on a company's balance sheet and income statement. GSCF and SCOR are two popular process frameworks in supply chain management [36]. Corporate strategy is the starting point of the GSCF framework, with the operational aspects of customer relationship management and supplier relationship management linked to the strategy. Its process metrics are related to EVA. On the other hand, the SCOR framework focuses on transactional efficiency by integrating operational activities such as purchasing, operations, and logistics. It benchmarks process metrics to improve operational efficiency.

Ethanol can be made from agricultural residues like wheat straw and from crops dedicated to energy use, like switchgrass. We study the logistics aspects of this transformation and determine the main characteristics of the supply chain making ethanol from cellulose. Important to the final acceptability of ethanol as a transportation fuel is both the economics as well as the environmental aspect of using ethanol. In this study we analyze the buildup of cost as biomass is transformed into fuel. We also look at all the steps involved and describe them from a supply chain perspective We have found that the main cost components in the cellulosic ethanol production are biomass production, harvesting and ethanol refining. We have also found that the main factor in reducing the overall production cost is the biomass to ethanol conversion factor. The development of new technologies to convert biomass into ethanol becomes a critical issue to achieve the cost targets imposed in order to make ethanol more competitive with other sources of energy such as fossil fuels. An increase in the current conversion factor of 42% could potentially yield to a decrease of nearly 15% in the: total production cost of cellulosic ethanol.
(cont.) Other factors such as increasing the refining plant size and biomass yield can also help to reduce the production cost but we found its impact to be lower than that of the conversion factor. Finally, we also performed a strategic analysis of the entire supply chain to determine how is this industry likely to develop and who will have more bargaining power and therefore will realize most of the value and profits in the supply chain. Our analysis shows that in such a dynamic scenario as in the alternate energy industry, the best option is to build sustained advantage by strong alliances with different partners within the supply chain.

Full textAbstract:
Purpose: This research aims to enhance the current understanding and knowledge of the demand-supply chain management (DSCM) concept by determining its elements, benefits, and requirements, as well as by analyzing key elements of the concept. Methodology: This research has utilized the case study strategy and the survey strategy, however, the case study strategy dominates. The case study research has involved five companies originating from Sweden and the collection of empirical data mainly from in-depth interviews with key persons representing senior and middle management. The survey research targeted the largest firms in Sweden and Finland and empirical data was collected through an online questionnaire. Findings: This research has established that the main elements of DSCM include market orientation, coordination of the demand and supply processes, viewing the demand and supply processes as being equally important, as well as value creation, differentiation, innovativeness, responsiveness, and cost-efficiency in the demand and supply processes. It has also been revealed that the main benefits of DSCM include enhanced competiveness, enhanced demand chain performance, as well as enhanced supply chain performance, while the main requirements of DSCM include organizational competences, company established principles, demand-supply chain collaboration, and information technology support. A key element of DSCM further investigated is differentiation focused supply chain design. It has been shown that these efforts can be organized into a process of five stages. In addition, it is important that this process is addressed in parallel with the new product development (NPD) process, that information is exchanged between them, and that they are directed on the basis of the same segmentation model. Another key element of DSCM further investigated is coordination between NPD and SCM. This research has identified several significant linkages between these management directions, which motivate the use of an integrative NPD process where the NPD functions are aligned with the main supply functions in the company and other sales-related functions supporting the commercialization. A final key element of DSCM further investigated is the significance of regarding the demand processes and the supply processes as being equally important. This research has revealed that logistics outsourcing can be risky, if it results in the supply processes being considered less important. Nevertheless, if senior management regards the outsourced processes as equally important as the in-house processes, the effect of logistics outsourcing on company strategies and direction in SCM could be reduced and logistics outsourcing could instead provide an opportunity to improve the design and differentiation of the supply chain. Research limitations/implications: This research has proposed, described, and further analyzed a demand-supply oriented management approach. Such a management approach stresses that the demand processes and the supply processes have to be coordinated and directed at an overlying level, in order to gain and sustain a competitive advantage in competitive and fragmented markets. This research is mainly explorative in nature, and more empirical data, from similar and other research settings, is needed to further validate the findings. Another limitation of the research is that it is essentially limited to Swedish companies (even if some Finnish companies are involved in the survey), however, many of the case companies have a large international presence and are among the top three in their industries, facts which provide some grounds for generalization. Practical implications: This research provides researchers and practitioners with insights into how to develop a demand-supply oriented business. It shows that companies should organize themselves around understanding how customer value is created and delivered, as well as how these processes and management directions can be coordinated. In order for this to occur, the demand and supply processes must be considered as being equally important and the firm needs to be managed jointly and in a coordinated manner by the demand- and supply-side of the company. It is also important that value creation is considered in both the demand and supply processes. Originality/value: Despite strong arguments from both researchers and practitioners for a demand-supply oriented management approach only a minority of companies appear to have effectively coordinated the demand and supply processes. This might be influenced by the lack of research examining how the demand and supply processes can be coordinated, what benefits can be gained by coordinating them, and what requirements are necessary to succeed. This research contributes by investigating these types of aspects further.

Full textAbstract:
Ce travail de thèse est composé de cinq chapitres unis par une idée commune; celle que l'accumulation de capital n'est plus le facteur limitant de la croissance dans nos économies dévelopées, ce que je montre dans le chapitre 1. Dans ce contexte, un excès d'épargne peut naturellement conduire à l'émergence de bulles spéculatives. En particulier, ces bulles ont davantage tendance à apparaître sur les actifs qui peuvent être utilisés en garantie pour les emprunts, et ceux qui sont difficiles à vendre à découvert - notamment les actifs immobiliers. Je montre aussi que les bulles rationnelles peuvent très bien croître plus rapidement que le taux d'intérêt, et exploser de manière endogène aux contraintes institutionnelles. Une politique monétaire accommodante peut favoriser l'émergence de ces bulles comme les décourager, suivant le type d'actifs considéré (chapitre 2). Dans le chapitre 3, je montre que les bulles spéculatives peuvent amener simultanément une hausse de la consommation, de la production, de l'investissement, et des heures travailllées; elles pourraient donc être une alternative aux chocs de productivité pour expliquer les cycles macroéconomiques. Dans les économies ouvertes, les bulles immobilières expliquent ainsi les variations de comptes courants comme on le voit dans le chapitre 4, les actifs immobiliers étant majoritairement détenus par les résidents. Enfin, le chapitre 5 montre que la taxation du capital joue ici un rôle ambigu: d'un côté, elle décourage l'accumulation du capital; mais de l'autre, elle rend les liquidités disponibles pour l'accumulation du capital en diminuant l'offre d'actifs, notamment celle liée à la rente foncièreThis dissertation is composed of five chapters, all of which are united by the idea that capital is not scarce any more in our economies, and that the resulting low interest rates environment can open up the possibility for the emergence of rational speculative bubbles. The first chapter of the thesis uses national accounts and balance sheets data to show that capital income coming from investment is much lower than was previously thought, always lower than investment in Japan, which points to the idea of excess savings. In the second chapter of this thesis, I show that leverage and short-sales constraints are crucial in understanding the formation and the location of rational speculative bubbles. It generates procyclical leverage without the assumption of "scary bad news", return predictability, and equilibrium default. It helps us think about the effect of margin requirements, financial deregulation, and that of central bank's actions on asset prices. In chapter 3, I show that rational speculative bubbles can drive the business cycle, inducing positive comovement between consumption, hours worked, investment and production, thus being an alternative to productivity shocks to drive macroeconomic fluctuations. The results in chapter 4 suggest that asset overvaluations could drive international business cycles as well, inducing current account deficits. Finally, the chapter 5 is a first step towards thinking about capital taxation in a world with very abundant savings: on the one hand, capital taxation crowds out capital accumulation by discouraging savings, but on the other hand it reduces asset supply and thus helps free resources for investment

Cette thèse contribue au déploiement de l’infrastructure liée à l’énergie renouvelable qu’est l’hydrogène, en proposant de nouvelles stratégies basées sur des approches d’optimisation. Un état de l’art sur la conception de la chaîne logistique de l’hydrogène est préalablement réalisé, et permet d’identifier dans la littérature deux perspectives de recherche. La première concerne la couverture de la chaîne logistique globale, qui n’est pas assurée, d’une part en amont au niveau de la localisation des fournisseurs de matières premières et de l’approvisionnement des centres de production (aspect transport), d’autre part en aval au niveau de la localisation des points de distribution (stations-service) et de leur approvisionnement (transport). Pour intégrer ces composantes, un nouveau modèle de planification est élaboré. Il fusionne les modèles classiques, plus précisément un modèle de HSCND (Hydrogen Supply Chain Network Design) au niveau central, c’est-à-dire au niveau de la production et du stockage, et un modèle de HSRP (Hydrogen Refueling Station Planning) en bout de chaîne, qui considère la distribution. Ce nouveau modèle intègre également la prise en compte des sources d’approvisionnement. Il est exprimé sous forme d’un programme linéaire en nombres entiers mixtes, avec pour objectif la minimisation du coût de l’hydrogène à la pompe (LCOH). Son intérêt est validé par une étude de cas représentant la Franche-Comté en France.La seconde voie explorée est l’intégration des niveaux de décision stratégique et tactique. Il s’agit d’optimiser simultanément la localisation des stations-service et des tournées de ravitaillement de ces stations, en considérant comme actées les décisions prises précédemment depuis les sources d’approvisionnement jusqu’aux centres de production en hydrogène. L’objectif est de maximiser la capture du flux de demande, tout en minimisant le coût quotidien total. Deux algorithmes approchés sont développés pour résoudre ce problème, l’un basé sur une recherche adaptative de grand voisinage, l’autre sur un algorithme génétique. Le modèle et les algorithmes proposés sont appliqués à la région Bourgogne Franche-Comté en FranceThis thesis contributes to the deployment of the hydrogen infrastructures by proposing new strategies based on optimization approaches. A state of the art on the design of the hydrogen supply chain has been previously carried out, and allows to identify in the literature two research perspectives.The first one concerns the coverage of the entire supply chain, on the one hand upstream at the level of the location of raw material suppliers and the supply of production centres (transport aspect), and on the other hand downstream at the level of the location of distribution points (refueling stations) and their supply (transport). To integrate these components, a new planning model is developed. It merges the classical models, more precisely an HSCND (Hydrogen Supply Chain Network Design) model at the central level, i.e. at the level of production and storage, and an HSRP (Hydrogen Refueling Station Planning) model at the end of the chain, which considers distribution. This new model also integrates the consideration of supply sources. It is expressed as a mixed number integer linear program, with the objective of minimizing the least cost of hydrogen (LCOH). Its interest is validated by a case study representing Franche-Comté in France.The second research area explored is the integration of the strategic and tactical decision-making levels. The aim is to simultaneously optimize the location of refueling stations and the routes to supply these stations, by considering as actuated the decisions previously taken from the supply sources to the hydrogen production centers. The objective is to maximize the refueling demand flow captured, while minimizing the total daily cost. Two metaheuristic algorithms are developed to solve this problem, one based on an adaptive large neighbourhood search, the other on a genetic algorithm. The proposed model and algorithms are applied to the Bourgogne-Franche-Comté region in France

Thus, the best results in business are achieved by companies using the concept of integrated logistics, which allows you to combine the efforts of the managing personnel of the company, its structural divisions and logistics partners in a single chain: procurement - production - distribution - sales - service. The principles and methods of integrated logistics are aimed at obtaining optimal solutions, in particular, minimizing the overall logistics costs of the company.
Reducing all types of costs allows the company to free up financial resources for additional investments in warehouse equipment, information and computer systems, advertising, marketing research, etc.
Optimal logistic solutions can be obtained by the company’s management not only by the criterion of minimum total costs, but also by such key indicators as the lead time and the quality of the logistics service.In recent years, the interest of scientists and practitioners in the problems of logistics has been growing. The globalization of the market of goods and services, as well as global changes in information technology, require ensuring the clarity of physical supply flows as a necessary condition for the mandatory continuity of business processes. The methodological apparatus of logistics has proved the universality of its use in streamline process optimization in all areas of the national economy. Integrated logistics planning helps to increase the economic sustainability of companies in the market due to logistical coordination, which allows to find compromises between the functional units of the company and ensure its integrated interaction with the external environment.

In production planning for strong seasonal demand products, it is uneconomical to configure the supply chain for throughputs equivalent to the demand peaks. Instead, a holistic approach to supply chain optimisation is adopted where forward demand forecasts drive the production planning process. In this thesis, the medium-term supply chain planning components of forecasting, production planning and evaluation are addressed through studies on a paints production facility. With a large number of specialised products, family-level forecasting is adopted for its simplicity and practicality in applying forecast techniques, coupled with its benefits on the inception of new products into markets. A time-series component was incorporated into traditional clustering techniques for segmenting products into families. The dominant cluster profiles identified are attributed as the seasonal component for the subsequent generation of demand profiles. In multi-purpose batch plants, production planning involves the twin decisions of batch sizing and lot sizing, often performed in series. This campaign is optimised through augmenting the batch sizing operation within a lot-sizing model. In the Mixed Integer Linear Programming model developed here, the degrees of freedom are the monthly batch sizes of each product, integer number of batches of each product produced each month, amount of monthly overtime working and outsourcing required as well as the time-varying inventory positions across the chain. Values for these are selected to balance the trade-offs in batch costs and inventory costs as well as the overtime and outsourcing costs. The final section sees the development of stochastic, dynamic supply chain models to predict the effect of different inventory policies, taking into account forecast accuracy, as derived from clustering. Using Monte Carlo based simulations, the various supply and production decisions are assessed against process manufacturing performance indicators. These planning components are then reconfigured to derive an optimal paints supply chain.

The developed work is motivated by the hypothesis that the presented Supply Chain Business Model is a practical and comprehensive approach to support not only operational day-to-day business decisions, but most importantly strategic and long term decisions that may define the success and the longevity of a business. Conceptually, the Business Supply Chain Model developed in this thesis replicates the behaviour and decision making of the different agents in a supply chain, and an Optimisation Module determines the optimised parameters that maximise the overall business profit, whatever scenario it may be. In the optimisation module, a Genetic Algorithm was used to determine the best equation parameters for each individual agent that optimise the overall supply chain profit. Furthermore, several business case-scenarios are presented and the findings highlighted. These case-scenarios prove that: the HC model is robust when subjected to predictable or unpredictable causes of variability; the bullwhip effect can be reduced significantly by applying GA as the optimisation tool; the improvement of profits needs to be evaluated at a global scale, independently of the individual agents’ profit; impact of supply shortages in the SC ; retail expansion analysis; delivery patterns change impact in profitability; impact of sourcing decisions in the SC profitability; model suitability for seasonal vs. non-seasonal products. The SC Modelling framework generic and globalising approach means that is easily applied and transposed to any other business realities and it can be easily changed to reflect other SC scenarios. The costing model associated means that, at any point in the network, all costs and profits can be easily measured. For the first time the shelf-life of a product captured and losses of product due to BBE dates, quantified. In this model the optimisation methodology runs parallel to the developed simulation tool, so the optimisation should be only run for new scenarios.
