In a three stage supply chain composed of one manufacturer, one distributor and one retailer, the supply chain coordination mechanism is studied under a fuzzy demand environment. The market demand is treated as a positive trapezoidal fuzzy number, and the models of centralized decision-making system and spanning revenue sharing (SRS) contract are proposed by the method of the fuzzy set theory. ...

Development of every society is incumbent upon energy sector’s technological and economic effectiveness. The electricity industry is a growing and needs to have a better performance to effectively cover the demand. The industry requires a balance between cost and efficiency through careful design and planning. In this paper, a two-stage stochastic programming model is presented for the design o...

This paper studied pricing, service level, and production quantity decision problems in a supply chain with one manufacturer and one retailer under demand and production cost disruptions. The joint impact of demand and production cost disruptions on optimal pricing, service level, and production decisions in centralized and decentralized supply chain was analyzed, respectively. By solving the o...

Purpose – to model demand-driven chain networks on basis of multiple Customer Order Decoupling Points (CODPs). Design/methodology/approach – literature study and a case study in dairy industry, based on in-depth expert interviews. Findings – four main underlying factors of CODP diversity are addressed and modelled. Research limitations/implications – the proposed multiple CODP models provide th...

As supply chains become increasingly outsourced, the end-to-end supply network is often spread across multiple enterprises. In addition, increasing focus on lean inventory can often create significant supply/demand imbalances over a multi-enterprise supply chain. This paper discusses a set of integrated analytics for supply/demand synchronization with a new emphasis on customer facing actions c...

blood supply chain management is one of the mainchallenges in healthcare system. optimal locationof blood donation camps is one of the key factors in optimizing the bloodsupply chain. disruption in location of blood donation camps because ofdisasters will have a negative impact on the entire supply chain. thispaper develops a generalized network optimization model for the complex supplychain of...

In support of the order-to-delivery (OTD) business initiative, a simulation framework has been developed at GM R&D. The OTD simulation program is aimed at simulating the behavior of the OTD supply chain using detailed inputs associated with demand, supply, and production processes. Customer demand variation is a key source of uncertainty in GM’s supply chain. Early capture of customer demand fl...

Decision-making needs information. Enterprises in a supply chain make daily operating decisions on the basis of available information of demand and supply. The behaviors of supply chain members would be different under information sharing than otherwise. Demand-side information sharing has been intensively explored. However, supply-side information sharing has not been extensively investigated....

We study supply chain contracting with investment in demand forecasting under downstream competition. Supporting some recent industry observations, we show that under common pricing schemes, such as wholesale price or two-part tariff, downstream firms overinvest in demand forecasting. Analyzing the bounds and determinants of overinvestment, we demonstrate that the wholesale price and two-part t...
