Simetrik ve asimetrik enformasyon durumlarında tedarik zincirlerindeki kapasite kontratları

In this study, we focus on a two-party supply chain composed of a single manufacturer and asingle supplier where capacity is limited. We look into three different demand scenarios; price dependentdeterministic demand, stochastic demand and stochastic price dependent demand.In all three cases we try to improve the efficiency of the decentralized channel by consideringfive well-known contracts, namely, simple wholesale price contract, bonus contract, linear contract,cost sharing contract and revenue sharing contract.In this thesis, we do not specifically look for a coordinating contract but focuson the non-coordinating contracts as well as the coordinating ones,find the optimal contract parameters and compare the performances of different contracts with each other.We aim to find which contracts would be better to use for the companies depending on the system parameters,even if these contracts can not fully coordinate the supply chain,and if it is worth to look for a more complex but coordinating contract in these situations.We also compare the performances of the contracts for the asymmetric information models and analyzethe value of information in our models. Finally, through an extensive numerical study we investigate how the marketvariables will be affected under different contracts by the system parameters.
