Internal Markets for Supply Chain Capacity Allocation

McAdams, David, Malone, Thomas W. 08 July 2005 (has links)
This paper explores the possibility of solving supply chain capacity allocation problems using internal markets among employees of the same company. Unlike earlier forms of transfer pricing, IT now makes it easier for such markets to involve many employees, finegrained transactions, and frequently varying prices. The paper develops a formal model of such markets, proves their optimality in a baseline condition, and then analyzes various potential market problems and solutions. Interestingly, these proposed solutions are not possible in a conventional market because they rely on the firm's ability to pay market participants based on factors other than just the profitability of their market transactions. For example, internal monopolies can be ameliorated by paying internal monopolists on the basis of corporate, not individual, profits. Incentives for collusion among peers can be reduced by paying participants based on their profits relative to peers. Profit-reducing competition among different sales channels can be reduced by imposing an internal sales tax. And problems caused by fixed costs can be avoided by combining conditional internal markets with a pivot mechanism.

Maîtrise des incertitudes de l'environnement de la chaîne logistique : une analyse au regard du décalage entre théorie et pratique / Supply chain environmental uncertainties management : analysing the gap between theory and practice

Ruel, Salomée 29 August 2013 (has links)
Les entreprises industrielles évoluent désormais dans un environnement de plus en plus incertain. Ces incertitudes sont liées à la fois à l'amont et à l'aval de la chaîne logistique, mais aussi à la configuration interne de la chaîne et de ses systèmes d'information ou encore à des comportements organisationnels néfastes. Cette thèse a pour objectif de comprendre comment les entreprises industrielles gèrent les incertitudes présentes dans l'environnement de leurs chaînes logistiques. Notre recherche se déroule en deux étapes : une étude préliminaire et principale. L'observation participante menée en étude préliminaire a permis de montrer qu'une entreprise réputée en management de la chaîne logistique a choisi de restructurer ses ressources afin de diminuer la vulnérabilité de sa chaîne logistique. Ainsi, l'étude principale s'articule autour de l'approche basée sur les ressources et du courant des capacités dynamiques. La revue de la littérature montre que l'agilité et la résilience sont deux capacités dynamiques du management de la chaîne logistique. Mobilisant la méthode des cas comme heuristique permettant d'organiser la recherche, six études de cas sont menées au sein d'entreprises industrielles de tailles hétérogènes et de secteurs d'activités variés. Une fois les données collectées et codées sous forme de codage multithématique sur le logiciel NVIVO 8, les résultats s'organisent autour du protocole de cas. Ils retracent les incertitudes rencontrées par les entreprises industrielles et s'attachent à montrer quels outils, pratiques et stratégies sont développés pour diminuer la vulnérabilité. Ces outils, pratiques et stratégies sont des construits des capacités dynamiques et permettent d'identifier si les entreprises font preuves d'agilité et de résilience. Puis, les résultats montrent les difficultés au développement des capacités dynamiques et l'analyse identifie le manque de connaissance en management de la chaîne logistique comme barrière principale. La discussion de la thèse s'oriente autour de la connaissance comme réponse à l'incertitude. La thèse met en avant un décalage entre des connaissances académiques avancées en management de la chaîne logistique et des connaissances plus restreintes en entreprises. La littérature académique s'intéresse principalement aux entreprises matures en management de la chaîne logistique. Cependant, elles ne sont pas représentatives des autres entreprises industrielles. En s'intéressant au lien entre recherche, enseignement et pratique, il est possible d'identifier que le manque de connaissance en management de la chaîne logistique laisse un espace à la création d'effets de mode à la fois dans le monde de la pratique et de la recherche. Finalement, la thèse met en avant les conditions d'émergence de formes d'isomorphisme institutionnel dans les institutions universitaires, engendrant des effets de mode dans les travaux académiques, le tout n'ayant qu'un lien relatif avec la réalité empirique. / Industrial companies evolve from now on in a more and more uncertain environment. These uncertainties are linked to upstream and downstream the supply chain, but are also linked to the internal configuration of the supply chain and its information systems, or even linked to possible fatal organizational behavior. This thesis has for objective to understand how industrial companies manage their supply chains environmental uncertainties. The research takes place in two stages: a preliminary and main study. The participating observation led during the preliminary study showed that a company, famous in supply chain management, chose to restructure its resources in order to decrease the vulnerability of its supply chain. So, the main study is built around the Resource-based view based and around the dynamic capacities. The literature review shows that agility and resilience are two dynamic capacities of supply chain management. Using the case-study method as an heuristics allowing to organize the research, six case studies are conducted within industrial companies of heterogeneous sizes and varied business sectors. Once the data were collected and coded in the form of multithematic coding on the software NVIVO 8, the results get organized according to the case study protocol. They redraw the uncertainties met by industrial companies and attempt to show which tools, practices and strategies are developed to decrease the vulnerability. These tools, practices and strategies are some constructs of the dynamic capacities and allow identifying if companies show agility and resilience capabilities. Then, the results show the difficulties in the development of the dynamic capacities and the analysis identifies the lack of knowledge in supply chain management as the main barrier. The discussion of the thesis turns around knowledge as the answer to uncertainty. The thesis identifies a gap between strong academic knowledge in supply chain management and a more restricted knowledge in companies. The academic literature is mainly presenting the supply chain management held in mature companies. However, they do not represent other industrial companies. Focusing on the link between research, education and practice, it is possible to identify that a lack of knowledge in supply chain management leaves some room for the creation of latest fads in the world of practice and research. Finally, the thesis shows the emergence conditions for several forms of institutional isomorphism in the university institutions, engendering latest fads in the academic works, having only a relative link with the empirical reality.

A logistics optimization study for Garden City Co-op, Inc.

Kempke, Michael January 1900 (has links)
Master of Agribusiness / Department of Agricultural Economics / Brian C. Briggeman / Garden City Co-op, Inc. is a farm cooperative in Southwest Kansas. It provides marketing and storage of grain, fertilizer, crop protection products, seed, and petroleum to both member and non-member accounts. The cooperative also operates a transportation company called Western Transport. Western Transport provides transportation of anhydrous ammonia (NH3), liquid fertilizer (32-0-0 or 10-34-0), diesel, gasoline, and propane utilizing semi-tractors and trailers to Garden City Co-op, Inc. as well as to other agribusinesses in the region. The purpose of this thesis is to integrate and optimize the supply chain strategies for the cooperative’s fertilizer and petroleum products as it relates to storage and transportation of those commodities. Utilizing the framework of an aggregate production plan, a model is constructed to minimize costs associated with inventory holding, net storage asset depreciation after tax savings, net transportation asset depreciation after tax savings, labor, operations, and freight. By varying the quantities of petroleum and fertilizer the cooperative purchases, sells, and stores each month over a one-year period, an optimum mix of storage and transportation assets is determined. Two different demand scenarios are evaluated that relate to demand during a drought year versus demand during a non-drought year. Also, different model scenarios include varying beginning period inventory and ending period inventory to stress transportation assets versus storage assets. The model is optimized using a genetic algorithm solver in the software program Evolver produced by Palisade Corporation. Results of the optimization provided two feasible strategies for the cooperative. By continuing services to non-member accounts, there was a greater investment placed on transportation. Investments included additional trucks, NH3 trailers, petroleum trailers, and drivers. The strategy favored a just-in-time inventory approach versus inventory smoothing with storage. When discontinuing services to non-member accounts, investment between storage and transportation assets were relatively equal. The model favored a reduction in NH3 trailers, liquid fertilizer trailers, trucks, and drivers. However, additional storage was necessary as well as petroleum trailers. The scenario favored an inventory smoothing approach across the model year.

Integration of lean six sigma with multi agent systems in the food distribution industry in small to medium enterprises

Algassem, Fahed Suliman January 2016 (has links)
The service industry worldwide continues to face unprecedented challenges in decision-making and in managing the operations involved in delivering products at low cost and ever-faster delivery speeds. These pressures exert an even greater impact upon small- and medium-sized enterprises (SMEs) involved in this industry who, influenced by globalisation, have to respond by handling the dynamic complexity within their operational supply chain. Many larger firms have implemented Lean and Six Sigma (LSS) and end-to-end integrated real-time information systems (RTI) that provide the information and the mechanisms needed to support flexibility and prompt decision-making. The recent emergence of new technologies such as multi-agent systems (MAS) provides enhanced capability to address complexity and decision-making with greater ease of use at a reduced cost. Whilst the application of Lean and Six Sigma are supported by significant published research, the application of integrated LSS and MAS in food distribution, especially in SMEs, is not. This study seeks to provide research to address this shortcoming for SMEs within the food distribution sector within Saudi Arabia, how this integrated approach can offer considerable performance improvement in SMEs and provide a base for further contributions in this field. This research undertook an empirical case study in Saudi Arabia to test the application of LSS in a food distribution SME. This approach demonstrated a significant improvement in the Six Sigma for late delivery. A single-stage MAS application extended this improvement, demonstrating that there is value in its application. The study conducted a survey of 39 firms in this sector to gain an insight into their current practices and challenges. The findings indicated there was a lack of Lean and Six Sigma principles adopted and that a lack of use of interconnected real-time systems to support decision-making and complex operational SCs. These findings identified the opportunity to design a conceptual framework with a stepped approach that integrated LSS with MAS, which was then developed on a Java-Assisted DEvelopment Framework (JADE) platform and tested using real-world data in an SME empirical case study. The results of the sequence of applications and the final simulations proved that this integrated Lean multi-agent system (LMAS) solution offered such substantial improvements in quality, time and costs that the SME considered that those factors justified making its implementation a priority.

An evaluation of the value of security in the international marine supply chain

Loke, Wai Leng 05 1900 (has links)
Since the events of 9/11, there has been tremendous amount of renewed interests in the study of trade security. There has been an influx of security regulations and the private sector has been trying to keep pace in complying with them. However, due to the public externalities of security improvements and the lack of quantified and proven benefits, the private sector is struggling to establish business cases for their security initiatives. There is very little quantitative research in this area. Using exploratory factor analysis (EFA) and structural equation modeling (SEM), this study serves to fill this gap by introducing a statistical way of analysing and understanding the complex relationships amongst security effort, its motivators and performance and traditional supply chain performance (SCP). This study also proposes an evaluation framework for security efforts. EFA results show that security is a dimension of SCP. This means that organizations have all along been measuring an aspect of their operations that relates to security. As such, organizations should not perceive the current heightened interests in security as throwing them off-balance. In evaluating security efforts, organizations should select key performance indicators (KPIs) that represent each of the four areas of information, cargo, people and cost. SEM results show that organizations undertake security efforts as a result of both perceived security benefits and perceived collateral benefits, with perceived security benefits carrying a greater weight in the decision-making process. Results also show that organizations are implementing security initiatives out-of-compliance i.e. implementing initiatives that they perceive as not having significant impacts on security and SCP. In view of the positive relationships among perceived security impact, security effort and security performance, there is further imperative for an objective method for evaluating security efforts to prevent effort justification behaviour in determining the effectiveness of the same. Results also show that organizations perceive an improved performance in security leads to an overall improvement in SCP. However, as with other supply chain strategies, there are tradeoffs and not all aspects of SCP are impacted in the same way. Time, responsiveness and efficiency for instance are negatively impacted while reliability is positively impacted. / Business, Sauder School of / Operations and Logistics (OPLOG), Division of / Graduate

A distributed blockchain ledger for supply chain

Wu, Haoyan January 2017 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Affordable and reliable supply chain visibility is becoming increasingly important as the complexity of the network underlying supply chains is becoming orders of magnitudes higher compared to a decade ago. Moreover, this increase in complexity is starting to reflect on the cost of goods and their availability to the consumers. Optimizing the physical distribution phase in supply chain by providing increased visibility to trading partners can directly reduce product cost. Current supply chain information systems often lack the ability to cost-effectively relay ground truth in- formation in near real time to all stakeholders and most importantly to the supplier and the customer during the transport of the shipment. This thesis presents a solu- tion that addresses this gap through a distributed architecture. The solution enables small, medium and large businesses to interact in a dynamic and shipment-centric manner through a private blockchain sub-ledger that digitizes the transfer of custody for each shipment. Information in this private ledger is augmented by a public event ledger that reflects the movement of the shipment in real time. Third party monitors are engaged in the validation of the geolocation of the shipments by posting their physical proximity in the form of events to the public ledger.
