Optimization of a Dual-Channel Retailing System with Customer Returns

A plethora of retailers have begun to embrace a dual-channel retailing strategy wherein items are provided to consumers through both an online store and a physical store. As a result of standards and competitive measures, many retailers provide buyers who are unhappy with their purchases with the ability to achieve a full refund. In a dualchannel retailing system, full reimbursements can be done through what is called a crosschannel return, when a buyer purchases a product from an online store and returns it to a physical store. They can also be done through what is called a same-channel return, when a buyer purchases a product from a physical store and returns it back to the physical store, or purchases a product from an online store and returns it back to the online store. No existing research has examined all common types of customer returns in the context of a dual-channel retailing system. Be notified that the practice of cross-returning an item purchased from the physical store back to the online store is not common. Thus, it is not considered in this dissertation. We first study the optimal pricing policies for a centralized and decentralized dual-channel retailer (DCR) with same- and cross-channel returns. We consider two factors: the dual-channel retailer’s performance under centralization with unified and differential pricing schemes, and the dual-channel retailer’s performance under decentralization with the Stackelberg and Nash games. How dual-channel pricing behaviour is impacted by customer preference and rates of customer returns is discussed. In this study, a channel’s sales requests is a linear function of a channel’s own pricing strategy and a cross-channel’s pricing strategy. The second problem is an extension of the first problem. The optimal pricing policies and online channel’s responsiveness level for a centralized and decentralized dual-channel retailer with same- and cross-channel returns are studied. Indeed, the online store is normally the distribution centre of the enterprise and is not limited to the customers in its neighbourhood. Also, the online store experiences a much higher return rate compared to the physical store. Thus, it has the capability and the need to optimize its responsiveness to customer returns along with its pricing strategy. A channel’s sales requests, in the second problem, is a linear function of a channel’s own price, a crosschannel’s price, and the online store’s responsiveness level. The third problem studies the dilemma of whether or not to allow unsatisfactory online purchases to be cross-returned to the physical store. If not properly considered, those returns may create havoc to the system and a retailer might overestimate or underestimate a channel’s order quantity. Therefore, we study and compare between four vi different strategies, and propose models to determine optimal order quantities for each strategy when a dual-channel retailer offers both same and cross-channel returns. 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

Myopic Versus Farsighted Behaviors in a Low-Carbon Supply Chain with Reference Emission Effects

The increased carbon emissions cause relatively climate deterioration and attract more attention of governments, consumers, and enterprises to the low-carbon manufacturing. This paper considers a dynamic supply chain, which is composed of a manufacturer and a retailer, in the presence of the cap-and-trade regulation and the consumers’ reference emission effects. To investigate the manufacturer’s behavior choice and its impacts on the emission reduction and pricing strategies together with the profits of both the channel members, we develop a Stackelberg differential game model in which the manufacturer acts in both myopic and farsighted manners. By comparing the equilibrium strategies, it can be found that the farsighted manufacturer always prefers to keep a lower level of emission reduction. When the emission permit price is relatively high, the wholesale/retail price is lower if the manufacturer is myopic and hence benefits consumers. In addition, there exists a dilemma that the manufacturer is willing to act in a farsighted manner but the retailer looks forward to a partnership with the myopic manufacturer. For a relatively high price of emission permit, adopting myopic strategies results in a better performance of the whole supply chain

Coordinating Dual-Channel Supply Chain Under Price Mechanism With Production Cost Disruption

This paper studies a two-stage dual-channel supply chain consisting of one manufacturer and one traditional retailer. The manufacturer has its own online channel when he sells the product to the offline retailer. There exists a Stackelberg game between the manufacturer and the offline retailer, in which the manufacturer is the leader and the retailer is the follower. The manufacturer abandons the pricing right in the online channel and adopts the marketing strategy which the online retail price is equal to the offline one. When the supply chain is in a static (undisrupted) condition, it can obtain Pareto improvement and eventually be coordinated by a two-part-tariff contract with a one-time transfer payment. When disruptions make the manufacturer’s unit production cost change, we can obtain the retail price, the production quantity and the total supply chain profit under different disruption levels in the centralized supply chain. Then, we find that there are some certain robustness both in the manufacturer’s production quantity and in the offline retail price. When the supply chain is decentralized, we can coordinate the supply chain by changing the wholesale price according to different disruption levels. Finally, some numerical examples are presented to illustrate the results

SUPPLY CHAIN RISK MANAGEMENT IN AUTOMOTIVE INDUSTRY

The automotive industry is one of the world\u27s most important economic sectors in terms of revenue and employment. The automotive supply chain is complex owing to the large number of parts in an automobile, the multiple layers of suppliers to supply those parts, and the coordination of materials, information, and financial flows across the supply chain. Many uncertainties and different natural and man-made disasters have repeatedly stricken and disrupted automotive manufacturers and their supply chains. Managing supply chain risk in a complex environment is always a challenge for the automotive industry. This research first provides a comprehensive literature review of the existing research work on the supply chain risk identification and management, considering, but not limited to, the characteristics of the automotive supply chain, since the literature focusing on automotive supply chain risk management (ASCRM) is limited. The review provides a summary and a classification for the underlying supply chain risk resources in the automotive industry; and state-of-the-art research in the area is discussed, with an emphasis on the quantitative methods and mathematical models currently used. The future research topics in ASCRM are identified. Then two mathematical models are developed in this research, concentrating on supply chain risk management in the automotive industry. The first model is for optimizing manufacturer cooperation in supply chains. OEMs often invest a large amount of money in supplier development to improve suppliers’ capabilities and performance. Allocating the investment optimally among multiple suppliers to minimize risks while maintaining an acceptable level of return becomes a critical issue for manufacturers. This research develops a new non-linear investment return mathematical model for supplier development, which is more applicable in reality. The solutions of this new model can assist supply chain management in deciding investment at different levels in addition to making “yes or no” decisions. The new model is validated and verified using numerical examples. The second model is the optimal contract for new product development with the risk consideration in the automotive industry. More specifically, we investigated how to decide the supplier’s capacity and the manufacturer’s order in the supply contract in order to reduce the risks and maximize their profits when the demand of the new product is highly uncertain. Based on the newsvendor model and Stackelberg game theory, a single period two-stage supply chain model for a product development contract, consisting of a supplier and a manufacturer, is developed. A practical back induction algorithm is conducted to get subgame perfect optimal solutions for the contract model. Extensive model analyses are accomplished for various situations with theoretical results leading to conditions of solution optimality. The model is then applied to a uniform distribution for uncertain demands. Based on a real automotive supply chain case, the numerical experiments and sensitivity analyses are conducted to study the behavior and performance of the proposed model, from which some interesting managerial insights were provided. The proposed solutions provide an effective tool for making the supplier-manufacturer contracts when manufacturers face high uncertain demand. We believe that the quantitative models and solutions studied in this research have great potentials to be applied in automotive and other industries in developing the efficient supply chains involving advanced and emerging technologies

Pricing Policies for a Dual-Channel Retailer with Cross-Channel Returns

Many retailers are adopting a dual-channel retailing strategy (DCRS) in which products are offered through two channels: physical stores and online stores. Due to regulations or competitive measures, such a strategy allows customers who find a purchase unsatisfactory to obtain a full refund through a same-channel return or a cross-channel return. No papers have collectively studied the aforementioned types of customer returns in a dual-channel context. This paper studies optimal pricing policies for a centralized and decentralized dual-channel retailer (DCR) with same- and cross-channel returns. How dual-channel pricing behavior is impacted by customer preference and rates of customer returns is discussed. It is found, through sensitivity analysis, that when a channel with significant customer preference faces a high rate of returns, decentralized channels generate a greater system profit for retailers than coordinated channels that have a unified pricing strategy. A DCR with a Stackelberg scheme has the proclivity to be more profitable when under the leadership of a channel with a high rate of returns and significant customer preference

Power Struggle in the Food Chain? Lessons from Empirical Studies on Power Influences in Chains and Marketing Channels

Power plays a key role in any chain relationship. In the past large manufacturers such as Unilever and Nestle were the most dominant players in the chain. However, as a result of consolidation among retailers, power has shifted towards retailers. Nowadays such retailers as Wal-Mart, Carrefour, and Tesco are seen as powerful gatekeepers controlling the access to the end consumer. Moreover, branded manufacturers and large multinational retailers become increasingly dependent on fewer and larger suppliers who can deliver high quality products at competitive prices. Since many decades there is discussion going on about the role of power in chains and marketing channels. In order to understand how power and its interactions with other constructs in the chain can be used beneficially for management of the whole chain, it is of great importance to investigate the influences and effects of power. Some of the phenomena which are said to be influenced by power include performance, satisfaction, commitment, relationship quality, conflict, compliance, problem solving, chain integration and collaboration. In this context, the aim of our work is to analyze and systemize existing empirical studies, which measure the influences of power on other phenomena, and discuss the strengths and weaknesses of existing conceptualizations of power, in order to add clarity to the existing turmoil in the literature and contribute to the understanding of the role of power in chains and marketing channels for managerial purposes.Power, Power Conceptualization, Supply Chain, Supply Chain Network, Marketing,

Uneven Growth: A Framework for Research in Development Economics

The textbook paradigm of economy-wide development rests on the premise of "balanced growth"; that is, on the presumption that all sectors will grow in unison over time as a country gets richer. This view has served us reasonably well in some circumstances, but is not particularly useful for accounts of modern (under)development.In many developing countries, economic growth has been fundamentally uneven: software development, the outsourcing of services, sectoral technological change, quick compositional shifts between agriculture and other sectors, the rise of particular exports, "special" economic zones, and so on. This paper will discuss both the sources of uneven growth, and its implications, with greater emphasis on the latter. The paper will argue that much of the distributional issues, or the reactions to globalization that we see in modern developing societies can be viewed as reactions to a growth process that is fundamentally uneven and is indeed perceived as such.Balanced Growth; Economic Development; Globalization

Strategy and Profitability: Managing Profits in Inflation Economy

The inflation rate in Dubai, United Arab Emirates (UAE) rose to 5-year highs in 2014 and higher by 28% in the first half of 2015. This situation has challenged business managers to sustain business goals. Guided by Kaplan and Norton\u27s balanced scorecard framework. the purpose of this multiple case study was to explore strategies business managers use to maintain profitability with rising operating costs. Two organizations in Dubai, United Arab Emirates were purposefully sampled for this multiple case study. Data were collected through multiple semistructured interviews of a single senior manager from each organization, then triangulated with company e-mails and focus group interviews of 2 junior managers from each of the organizations. All data were analyzed using a 5-phased cycle of compiling, disassembling, reassembling, interpreting, and concluding to understand the emerging patterns. The themes revealed cost reduction initiatives and revenue enhancements initiatives as the key strategies used by the business managers. The approach and direction used in these strategies showed variance based on cost and revenue drivers of the organizations. The findings of the study can be a guide for business managers to understand the essence of effective business strategies that counter challenging economic environments, thus sustaining profitability and developing additional employment opportunities for the surrounding community
