Book excerpt: Integrating forward and reverse supply chains has proven to be a challenging task due to the differences in the nature of the activities that make up the forward and reverse flows. With the increasing concerns over environmental degradation, legislative compliance, diminishing supply of raw materials, and consumer demands for eco-friendly products, companies have begun designing the traditional supply chain paths to form a closed loop to facilitate recycling and reuse of product returns. The integration of forward and reverse supply chains is termed as Closed Loop Supply Chains (CLSC). Largely driven by its profitable business propositions, CLSC practices help to achieve both financial success and environmental benefits. Given that the annual estimate of commercial returns in the US is in excess of $100 billion and huge potential for using the value in the returned products, this dissertation develops optimization models for the design of a CLSC network for commercial returns by explicitly considering the various aspects of product returns, refurbishing costs, and customer acceptance of refurbished products.We first consider a four stage CLSC network for a single product incorporating customer acceptance rate for refurbished products. We develop an optimization model, called the Base model, to determine the optimal locations of the facilities and the distribution of flows between the facilities in the CLSC to maximize the total profit and illustrate it using a realistic example. The results from the sensitivity analysis show that the total supply chain profit increases with the increase in refurbishing activity. The changes in product return parameters lead to changes in the optimal network design, implying the need to explicitly consider the uncertainty in these return parameters. We also observe that the refurbishing cost has an effect on the network design decisions implying the need to include it in the model. Quality of product returns vary depending upon how long the product has been in use, nature of defects, shipping damages etc. In this research, we consider four tiers of product returns, based on the quality of returned products and their refurbishing costs. Buying behaviour of the quality-sensitive high-end customers and price-sensitive low-end customers vary with respect to the price of the refurbished products. We extend our Base model considering the four tiers of product returns, their quality and the customer behaviour towards buying refurbished products. It is called the Extended Base model. We show that the inclusion of the tiers of product returns and customer behaviour towards buying refurbished product increase the supply chain profit. Using sensitivity analysis, we show that the quality of the returned products is an important factor in determining the optimal discount rates for the refurbished products. We also show that the network design varies with the customer acceptance rates of the refurbished products. Network design models are intrinsically multi-objective in nature. The Extended Base model is reformulated with two objectives: maximize profit and minimize energy usage in the warehousing facilities and transportation. We develop a bi-criteria MILP model for the problem and illustrate it using a realistic example. An interactive optimization algorithm is proposed to solve the bi-criteria problem. The algorithm poses less cognitive burden on the decision maker and converges faster to the best compromise solution. Product return parameters, customer demands, and customer acceptance of the refurbished products, are unpredictable. We model these uncertainties using a set of discrete scenarios with associated probabilities. A scenario-based robust optimization model is then developed to maximize the expected profit of the supply chain along with minimizing the variability of the profit across the scenarios. Minimizing the variability is necessary to mitigate the risk associated with the uncertain input parameters in the supply chain. The model is illustrated with an example. We provide a comparison between the robust optimal solution and the deterministic design solution. We show that the expected profit and the customer responsiveness are higher in the robust design compared to its deterministic counterpart.

This book was released on 2012-12-06 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic, marketing, and legislative considerations are increasingly leading companies to take back and recover their products after use. From a logistics perspective, these initiatives give rise to new goods flows from the user back to the producer. The management of these goods flows opposite to the traditional supply chain flows is addressed in the recently emerged field of Reverse Logistics. This monograph considers quantitative models that support decision making in Reverse Logistics. To this end, several recent case studies are reviewed. Moreover, first hand insight from a study on used electronic equipment is reported on. On this basis, logistics issues arising in the management of "reverse" goods flows are identified. Moreover, differences between Reverse Logistics and more traditional logistics contexts are highlighted. Finally, attention is paid to capturing the characteristics of Reverse Logistics in appropriate quantitative models.

Available in PDF, EPUB and Kindle. Book excerpt: Supply Chain Network design is an important strategic decision that helps Original Equipment Manufacturers (OEMs) to position their supply chains for profitable reverse supply chains. We observe that between the competitors of technology products, companies such as HP and Xerox (printers) and Apple and Google (smartphones), one competitor (HP and Apple) manages the reverse supply chain to extract value in a profitable manner, while the other competitor (Xerox and Google) uses a third-party reverse logistics company to simply recycle consumer returns. In the literature, supply chain levers, such as consumer Willingness to Pay (WTP) for remanufactured products, managing the collection process of consumer returns, the quality of the consumer returns and the design of reverse logistics have been identified as key factors influencing OEM participation in reverse supply chain. In this thesis, we show that, under the same supply chain levers mentioned above, the OEMs approach to supply chain network design can significantly impact the profitability in the reverse supply chain over the product lifecycle. To address the supply chain network design problem for an OEM, we propose an integrated multi-period optimization model called Product Life Cycle Optimization Model (PLCOM), to design the Closed Loop Supply Chain (CLSC) for the OEMs. The PLCOM is a Mixed Integer Linear Program that consists of a Demand model and a Pricing model. The Pricing model determines the optimal production quantity and the selling price computed over the product life cycle, based on a realistic customer Willingness to Pay (WTP) for new and remanufactured products. The Demand model computes the demand for new and remanufactured products based on the Extended-Basss diffusion model. The PLCOM also computes the cannibalization of new product sales due to the introduction of remanufactured product and the availability of product returns for remanufacturing, constrained by the collection of the returns. The Demand and Pricing models are then integrated into a Mixed Integer Program (MIP) model to design the CLSC network.The PLCOM is applied to a realistic case study using Apples iPhone 7 for a product life cycle of 8 years. The final MIP model has 30 binary variables, 48066 continuous variables and 3972 constraints and was solved using CPlex in 0.1619 seconds. We show that an integrated approach to design the supply chain network by the OEMs is more profitable compared to a sequential approach, where the OEM initially designs the optimal forward supply chain network and implements it. Later, when the OEM decides to participate in the remanufactured market, the OEM revisits the network design to obtain the optimal CLSC for the reverse supply chain. Using sensitivity analysis, we also show that slow diffusing products are more profitable for remanufacturing and fast diffusing products require flexibility in capacity planning, in order to avoid the fixed cost of opening additional facilities. In the case of fast diffusing products, we also observe a delayed surge in demand for remanufactured products caused by a delayed cannibalization effect on new product demand. Finally, a sensitivity analysis on the quality of the consumer returns gives an upper bound on the investment that can be made by the OEM in incentivizing the consumers to improve the quality of the returns.In the technology industry, frequent new product releases entail OEMs to concurrently manage successive generations of products. For example, Apple currently sells multigeneration iPhones, such as iPhone 6S, iPhone 7, iPhone 8 and iPhone X. Hence, we extend the integrated model to a two-generation product setting. We model the demand for the second-generation product as a substitution for the first-generation product. We identify the \textit{logit} function as the substitution function to compute demand for the second-generation product and validate total sales using the iPhone4 and iPhone 4S sales data. The extended PLCOM is again used in a realistic case study based on the consumer WTP for iPhone 7 and iPhone 8 as the successive generations of products. The extended PLCOM has 30 binary variables, 77474 continuous variables and 6470 constraints and the optimization problem was solved using CPlex and the solver took 46 seconds to solve the problem. Finally, we conduct a sensitivity analysis to determine the most profitable time to introduce the second-generation product, characterize the slow and the fast diffusing products in the two-generation product setting and analyze the impact of the quality of consumer returns on the profit.
