Item Open Access Buyback and target rebate contracts when the manufacturer operates under carbon cap and trade mechanism = Karbon ticareti mekanizması altında çalışan bir üretici ile geri alma ve hedef satış indirimi kontratların analizi(2014) Ebadi, MalekIn this study, the coordination of a manufacturer and a retailer in a supply chain is considered, in a single period environment where the manufacturer has carbon emission restriction with trade option. The customer demand over a period is assumed to be a random variable with an arbitrary distribution. Two types of contracts, namely the buyback and the target rebate contracts are considered. For each type, the contract parameters which achieve channel coordination have been studied. The models show that for both contract types, under specific parameter settings coordination is achievable. In particular, we show that under a buyback contract with a carbon trader manufacturer, coordination can be achieved, even if no returns are allowed, contrary to the findings of Pasternack, who first studied a buyback contract in a setting where carbon emissions are not taken into consideration. The results are illustrated by numerical examples.Item Open Access Carbon restricted newsvendor problem under CVAR objective and resource constraints(2014) Korkmaz, ÖzümNewsboy problem has been studied in the literature extensively. The classical newsvendor, representing the risk neutral decision maker, determines the optimal order/production quantity by maximizing the expected profit or minimizing the expected total cost of a single period with stochastic demand. This approach is not suitable if one also aims to reduce the chances of facing unexpected losses due to demand uncertainty. In this thesis, two problems are investigated with a single product newsvendor under CVaR maximization objective. The first problem addresses the newsvendor model with two different carbon emission reduction policies, namely, mandatory emission allowance and carbon emission trading mechanism. In the second problem, as an extension of the first one, a newsvendor with multiple resource constraints is considered for the cases where the resources have quotas with trade options. Analytical expressions for optimal order/production quantities are determined together with the optimal trading policy and numerical examples are provided.
