Several decision making insights on choosing between the different cross-channel return strategies and some properties of the optimal solutions are presented. From the retailer's perspective of outsourcing the e-channel's management to a third party logistics and service provider, we finally study three different inventory strategies, namely transaction-based fee, flat-based fee, and gain sharing. For each strategy, we find both channels' optimal inventory policies and expected profits. The performances of the different strategies are compared and the managerial insights are given using analytical and numerical analysis. Methodologies, insights, comparative analysis, and computational results are delivered in this dissertation for the above aforementioned problems. vii DEDICATION My earnest gratitude and respect to my honourable parents Tomader Mansoury and Hassan Radhi for their unconditional love and endless care.

Allowing unsatisfactory online purchases to be cross-returned to the physical store together with same-channel returns is one of the practical strategies used in the dual-channel retailing industry. Many of those returns are intact and undamaged and, thus, can be resold. But there is a lack of the research on how those resalable returns impact the order quantities of each channel. In this paper we study and compare four different return policies where a dualchannel retailer offers both same-and cross-channel returns. For each return policy, we propose mathematical models to determine optimal order quantities that account for the impact of resalable returns. Several insights on the different cross-channel return policies and some properties of the optimal solutions are presented.

Quality of returns is stochastic, while demand for remanufactured products is either stochastic or deterministic. The problem we considered is to determine facilities to operate, minimum quality to accept into each operating facility, return quantity and demand allocation simultaneously so that the system's profit is maximized. The problem is formulated as a mixed integer nonlinear programming model. Through the use of a numerical example, the impact of quantity of returns, total spending, quality uncertainty, demand uncertainty, and transportation cost on the remanufacturing system is analyzed.

Many manufacturers and retailers have already opened online stores to sell their products. Thus, ... more Many manufacturers and retailers have already opened online stores to sell their products. Thus, manufacturers are competing as sellers, and retailers are transforming into dual-channel retailers (DCRs). Such an expansion in business scope and the wide spread of lenient return policies trigger tremendous return volume that requires great deal of logistical efforts. The service levels offered within online stores greatly affect channels’ demand. However, they also influence the channel choice of return for online customers, if applicable, when their purchases are unsatisfactory. Therefore, this paper studies the optimal service level for a centralized DCR. In addition, it examines the optimal levels for a decentralized two-echelon system through the implementation of Nash and Stackelberg theoretical frameworks. Important properties of optimal solutions and vital managerial insights have been devised through analytical and sensitivity analysis. It is found that a DCR may have the foll...
