DESIGNING A SUPPLY CHAIN MODEL WITH CONSIDERATION DEMAND FORECASTING AND INFORMATION SHARING  [cached]
S.M.T. Fatemi Ghomi,N. Azad
South African Journal of Industrial Engineering , 2012,
Abstract: ENGLISH ABSTRACT: In traditional supply chain inventory management, orders are the only information firms exchange, but information technology now allows firms to share demand and inventory data quickly and inexpensively. To have an integrated plan, a manufacturer not only needs to know demand information from its customers but also supply information from its suppliers. In this paper, information flow is incorporated in a three-echelon supply chain model. Also to decrease the risk of the supply chain system, the customers’ demands are predicted first and this prediction is then used as an input to the supply chain model. In this paper a proposed evolving fuzzy predictor model will be used to predict the customers’ demands. For solving the supply chain model, a hybrid heuristic combining tabu search with simulated annealing sharing the same tabu list is developed. AFRIKAANSE OPSOMMING: In tradisionele voorsieningskettingvoorraadbestuur verteenwoordig bestellings die enigste vorm van van inligting wat deur ondernemings uitgeruil word. Inligtingstegnologie laat ondernemings egter deesdae toe om vraag- en voorraadata vinnig en goedkoop uit te ruil. Om 'n ge ntegreerde plan te hê, het 'n vervaardiger nie alleen aanvraaginligting nodig van sy klante nie, maar ook aanbodinligting van sy leweransiers. In hierdie artikel word inligtingvloei geinkorporeer in 'n drie-vlakvoorsieningskettingmodel. Voorts, om die risiko in die voorsieningskettingmodel te verminder, word die klante se aanvraag eers vooruitgeskat en die vooruitskatting word dan gebruik as 'n inset tot die model. Hierdie artikel gebruik 'n groeiende wasige vooruitskattingsmodel om die klantebehoeftes voor uit te skat. Om die model op te los, word 'n hibriede heuristiese metode gekombineer met 'n "tabu"-soektog gebruik.
Enabling information sharing by establishing trust in supply chains: A case study in the South African automotive industry
Roxanne Piderit,Stephen Flowerday,Rossouw Von Solms
South African Journal of Information Management , 2011, DOI: 10.4102/sajim.v13i1.473
Abstract: Background: The significant economic importance of the country’s automotive industry provided the context for this study. The success of the industry relies on the effectiveness and efficiency of the supply chain, which can be significantly affected by the strength of the supply chain relationships. The role of trust and information sharing in relation to two key theories was considered, namely: organisational information processing theory and game theory. Previous studies have recognised the importance of trust and information sharing in supply chain relationships and considered the effect of trust on information sharing, or the effect of information sharing on trust in a single direction. Thus, the potential cyclical relationship between the two factors has been largely ignored. Objectives: This paper explored the relationship between trust and information sharing in South African automotive supply chains, and establishes the importance of nurturing a cyclical relationship between these two factors. In addition, the role of information technology (IT) in supporting this relationship was considered. By improving both trust and information sharing, the performance and competitiveness of the supply chain can be improved. Method: An examination of the effects of a lack of trust in a supply chain relationship, and the consequential lack of information flow, was conducted by means of a case study of an Eastern Cape-based automotive supplier. A case study research method was followed for this study, which made use of multiple data collection methods, including document survey and participant observations. The case selected is an East London based subsidiary of a larger multinational automotive component supplier to both local and international automotive original equipment manufacturers. Results: The findings led to the conclusion that the way forward for competitive supply chains is to build trust in the supply chain in order to improve information flow, and vice versa. Information technology can be used to nurture this cyclical relationship between trust and information sharing. Conclusion: It is proposed that simultaneously improving information flow and trust in an interorganisational relationship leads to improved supply chain performance and competitiveness.

Revue Médicale de l'Assurance Maladie , 2002,
Abstract: This article presents an analysis of the Swiss health care market’s federal legislative regulation framework, largely defined by the January 1, 1996 health insurance law (LAMal). In order to fully understand the impact of this law on the health care market, we also studied its application decree (OAMal) as well as certain research reports published by the Federal Health Insurance Office (OFAS) which offered preliminary elements for its evaluation. With a look toward the future, we also analysed the first two partial revision projects presented by the Federal Counsel (government), the report of the Commission on present-day, related questions and, finally, the results of the Policy National Health project. The measures taken in Switzerland for containing health care costs are exposed, distinguishing those that are aimed at controlling supply from those intended to manage demand. If up until now, priority has been given to controlling supply, demand management is becoming more and more important at a time when increased competition is entering the health care arena.
Coordination of Supply Chain under the Revenue Sharing-Advertising Cost Sharing Contract  [PDF]

Journal of Service Science and Management (JSSM) , 2017, DOI: 10.4236/jssm.2017.103024
Abstract: In this article, we study a two-echelon supply chain with a single manufacturer and a single retailer. In the case of advertising investment affecting the market demand, we use the theory of game theory, and respectively discuss the coordination of general revenue sharing contract and revenue sharing-advertising cost sharing contract. The results show that: the general revenue sharing contract cannot achieve supply chain coordination. However, revenue sharing-advertising cost sharing contract in a specific form can achieve supply chain coordination. And in the appropriate revenue sharing contract parameters, it can also achieve a win-win situation between the two sides.
Multi-Agent System Supply Chain Management in Steel Pipe Manufacturing  [PDF]

International Journal of Computer Science Issues , 2010,
Abstract: The proposed work focus large -scale scheduling in the steel pipe industry on the significance and benefits of operating supply chains as an integral part of the modern manufacturing enterprises and also the importance of information sharing as the major requirement for the effective functioning of supply chains. A multi-agent architecture for integrated dynamic scheduling of the steel pipe industry is proposed . The scheduling systems of these processes have different objectives and constraints, and operate in an environment where there is a substantial quantity of real-time information concerning production failures, supplier information , order processing and customer requests. Each process is assigned to an agent who independently, seeks an optimal dynamic schedule at a local level taking into account local objectives, real-time information and information received from other agents. Each agent can react to real-time events in order to fix any problems that occur.
Competition of two supply chains with different risk structures: applying market research option  [PDF]
A. Hafezolkotob,A Makui
International Journal of Industrial Engineering Computations , 2012,
Abstract: Demand uncertainty obliges all participants through a supply chain to make decisions under uncertainty. These decisions extend across price, investment, production, and inventory quantities. We take account of competition between two supply chains under demand uncertainty. These chains internally are involved in vertical pricing competition; however, they externally participate in horizontal pricing and service level competitions by offering a single-type product to the market. Since firms may have various attitudes against demand uncertainty and its related risks, different risk structures for competitive supply chains are considered. We assume that risk-averse firms are able to decrease demand uncertainty by information gathered from market research. For risk-averse participants in a chain, market research investment is an appropriate ground for vertical coordination, which diminishes risk through a supply chain. Optimal strategies based on game theory are obtained for different risk structures; furthermore, for each structure the effects of risk sensitivity as well as market research efficiency on these optimal strategies are investigated. Finally, we propose two scenarios for information sharing between risk-averse participants.
Supply Chains Competition under Uncertainty Concerning Player’s Strategies and Customer Choice Behavior: A Generalized Nash Game Approach

Mathematical Problems in Engineering , 2012, DOI: 10.1155/2012/421265
Abstract: Decision makers in a supply chain confront two main sources of uncertainty in market environment including uncertainty about customers purchasing behaviors and rival chains strategies. Focusing on competition between two supply chains, it is considered that each customer as an independent player selects products of these chains based on random utility model. Similar to quantal response equilibrium approach, we take account of customer rationality as an exogenous parameter. Moreover, it is assumed that decision makers in a supply chain can perceive an estimation of rival strategies about price and service level formulated in the model by fuzzy strategies. In the competition model, chain’s decision makers consider a subjective probability for wining each customer which is formulated by coupled constraints. These constraints connect chains strategies regarding to each customer and yield a generalized Nash equilibrium problem. Since price cutting and increasing service level are main responses to rival supply chain, after calculating optimal strategies, we show that more efficient responses depend on customer preferences.

A case study illustrates the applicability of the proposed mathematical model.
Strategic nature of the logistics customer service in the supply chain
LogForum , 2010,
Abstract: Logistics customer service in the supply chain considerably differs from the binary relation described in the literature in which one supplier provides services to scattered recipients. The difference is manifested in the fact that an institutional client in the supply chain has much greater and often different requirements than the end consumer, at the same time appearing in a dual role of the supplier and the customer; and first and foremost, should take an active part in creating and implementing a supply chain strategy. If this strategy is to contribute to success, it must be based on cooperation among the supply chain participants, aimed at generating value for the end customer. Supply chain participants should establish partner relations reflected in such service to their customers which would encompass the maximum of their extended criteria of supplier evaluation. They should, however, first and foremost, take into account their maximized contribution to the final effect of the supply chain. Hence, every supply chain should develop a clear strategy determining the role of individual companies in creating the most favourable offer for the end customer.
Supply Chain Management Or Adaptive Business Network? – Coordination Versus Collaboration  [PDF]
Ilies Liviu,Crisan Emil
Annals of the University of Oradea : Economic Science , 2008,
Abstract: You are not the only company capable to create value for your clients. For making valuable products, for performing high standard services, one company is no longer enough in this new informational era, in this new needs era. Better business performing means now to satisfy more complex needs quicker than ever. Could one company face this challenge alone? Is there another way? Collaboration may be the answer. Maybe the most well-known term when it comes to collaboration between companies is Supply Chain. Why Supply Chain, why Supply Chain Management (SCM)? This article presents the answers to these questions, but also presents different approaches regarding SCM: the logistics approach regarding supply chain management, the strategic approach, the new entrepreneurial approach, supply chain as a win-win game. New paradigms regarding collaboration appeared regarding business collaboration: Adaptive Business Network (ABN). Do these new concepts imply the dead of SCM? Or are them only a new wave in SCM terminology and business orientation? Our conclusion is that these new approach is a normal change in business: businesses are made by people and people don’t like to be conducted (managed). The old-fashioned SCM was based on a coordinator versus several obedients relation. It is absolutely normal to dream at freedom and to be not very efficient while you have to play after somebody else rules. ABN is in the other side of human relations and also business relations – it insists on partnering. Everybody is a part of a chain which has as its main goal customer satisfaction, has the right to make proposals, to negotiate, and to be a winner. Of course, ABN appearance does not involve SCM disappearance, but change in how some chains are managed, in how some chains function. We shall see for the future if an organization with several brains is more successful.
