Analysis of an inventory system with advance emand information and supply uncertainty
Arıkan, Emel; Süral, Haldun; Department of Industrial Engineering (2005)
In this study we address a periodic review capacitated inventory system with supply uncertainty where advance demand information is available. A stochastic dynamic programming formulation is applied with the objective of minimizing the expected inventory related costs over a finite horizon. Three different supply processes are assumed. Under the all-or-nothing type supply process and partially available supply process, the structure of optimal policy is proved to be a base stock policy and numerical example...
Analysis of a Revenue Sharing Contract in a Reverse Supply Chain
Bakal, İsmail Serdar (2017-09-06)
ginal Equipment Manufacturers that engage in the remanufacturing business fully or partially outsource take back activities. Although outsourcing reverse activities seems to be a reasonable option, it may result in significant inefficiencies due to decentralization. Several contracting mechanisms have been proposed to reduce the inefficiencies in the forward chains. However, the effectiveness of these contracts has not been fully investigated in reverse chains. In this study, we investigate a two-echelon...
Analysis of price-only and revenue sharing contracts in a reverse supply chain
Biazaran, Majid; Bakal, İsmail Serdar; Department of Industrial Engineering (2016)
Original Equipment Manufacturers prefer to fully or partially outsource take-back activities, such as used product acquisition and handling, since dealing with reverse flow of goods is not their core competency. However, outsourcing may cause the supply chain to suffer from local optimization that results from decentralization. In such cases, different forms of contracts are offered to reduce the effects of decentralization. In this study, we consider a two-echelon reverse supply chain where a remanufacture...
Analysis of a two-echelon multi-item inventory system with postponement
Eryılmaz, Hande; Meral, Fatma Sedef; Department of Industrial Engineering (2010)
Increased product proliferation and global competition are forcing companies within the supply chain to adopt new strategies. Postponement is an effective strategy that allows companies to be agile and cost effective in dealing with the dynamics of global supply chains. Postponement centres around delaying activities in the supply chain until real information about the market is available, which reduces the complexity and uncertainty of dealing with a proliferation of products. A two-echelon divergent suppl...
