Özet (Çeviri)
This dissertation consists of two essays, each focusing on an important topic in retail operations. These topics are each summarized below. In the rst essay, we investigate the optimal pricing and package size decisions of a retailer selling a perishable product either in packages or in bulk. Bulk sale is de ned as selling the product in a container (instead of packages) that allows customers to buy as much or as many as they want. We analyze how adding a bulk sale option a ects the optimal decisions, when it is optimal to o er the product in package/bulk and when it is optimal to o er both at the same time. We also investigate implications of the pricing and package size decisions as well as the bulk sale option on the food waste at the consumer level. According to our results, when the market is homogeneous, selling the product in packages instead of bulk gives twice more pro t to the retailer but it also gives twice more relative waste. When the market is heterogeneous with two consumer segments, adding a bulk sale option could increase expected pro t up to 12 percent and could decrease relative waste up to 8 percent. In the second essay, we work on the multi-period assortment problem for a retailer with variety-seeking/avoiding consumers. If consumers are variety-seeker, they are not likely to buy the same product in two subsequent periods. If customers are variety-avoidant, their probability of repeat purchase is high. We assume that each consumer`s variety seeking/avoiding tendency is characterized by a parameter V 2 [1; 1]. In our analysis, we consider two di erent rm types which we call the Dynamic and the Static rms. The Dynamic rm optimizes the pro t over the entire horizon by changing (if necessary) the assortment o ered in each period dynamically, whereas the static rm has to decide one assortment to o er throughout the horizon. We provide some structural results for the nite and in nite horizon versions of the problem. We show that the existence of variety seeking/ avoiding behavior decreases the retailer`s pro t. For the in nite horizon problem, we show that the static rm's optimal assortment is a popular-eccentric set and for some cases repeating to cycle between two assortment yields more pro t than o ering the same in each period.
