Özet (Çeviri)
In the majority of classical supply chain management and inventory theory literature,demand arises from exogenous sources upon which the firm has little or no control. Inmany practical contexts, however, enterprises have numerous tools to generate, shapeand manipulate the demand they face. This phenomenon introduces a new dimension tosupply chain planning problems; the interaction and coordination between the demandand supply side of the supply chain. In our study, we introduce and study demandmanagement tools that are integrated into classical supply chain planning models.We present a nonlinear, combinatorial optimization model to address planningdecisions in both deterministic and stochastic supply chain settings, where a firmconstructs a demand portfolio from a set of potential markets having price-sensitivedemands. We first consider a pricing strategy that dictates a single price throughout allmarkets and provide an efficient algorithm for maximizing total profit. We also analyzethe model under a market-specific pricing policy and describe its optimal solution. Anextensive computational study characterizes the effects of key system parameters on theoptimal value of expected profit, and provides some interesting insights on how a givenmarket?s characteristics can affect optimal pricing decisions in other markets.We analyze the implications of order timing decisions in multi-retailer supply systemsin a single period, newsvendor setting. Specifically, we investigate a supply chain withmultiple retailers and a single supplier where one of the retailers is considered a preferredor primary customer of the supplier. We compare the expected supplier and retailer profitsunder two order commitment strategies and specify conditions under which a particularcommitment scheme benefits the supplier, the primary retailer, and the entire system. Wecompare our findings to a single-retailer system, and investigate the effects of capacitatedsupply. Observing that the outcome of the strategic interaction between the supplier andhis primary customer is not in alignment with the supplier?s preference, we propose andevaluate a number of demand management tools that the supplier can utilize in order toachieve his desired order commitment scheme. These tools include a capacity limit on theproduction quantity of the supplier, reallocation of the leftovers to the primary customerafter demand realizations, and offering a discounted wholesale price. We also perform acomparative analysis of these tools and assess their effectiveness under various settingsthrough a computational study.
