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.

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.

Download or read book Optimization Modeling for the Operation of Closed loop Supply Chains written by Aman Gupta and published by . This book was released on 2007 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmentally conscious manufacturing and remanufacturing/recycling of end-of-life products are steadily growing in importance. The problem of managing the waste generated due to the disposal of many types of products has many aspects. The main driving forces for solving this growing problem are the rapid diminishment of raw material resources, decreasing space in landfills and increasing levels of pollution. The drivers associated with these forces are governmental regulations which require that the manufacturers take back the end-of-life products and customer perspectives on environmental issues. This research considers the problem of increasing levels of electronic and electrical equipments waste. The implementation of closed-loop supply chains can be beneficial both economically and ecologically for these problems. Relevant literature to understand various issues involved in the operation of reverse logistics systems and closed-loop supply chains is reviewed. Upon reviewing the issues involved in closed-loop supply chains, the problem is considered as an ill-structured problem. A problem structuring technique called Why-What's Stopping Analysis is used to analyze the problem from various perspectives. Also, since a closed-loop supply chain involves multiple objectives, two techniques for categorizing the objectives into fundamental and means objectives are presented: Fundamental Objective Hierarchy and Means Objective Network techniques, respectively. A Goal Program (GP) modeling approach is used to handle many of the objectives identified by the previously mentioned techniques. In this research a consolidated objective function is defined which includes all of the deviational variables considered in various goals defined in the model. The consolidated goal is to minimize the weighted sum of all deviational variables. A non preemptive goal programming approach has been used with goals being assigned different weights according to their priorities. The values of the deviational variables help the decision maker to see which of the different goals are satisfied with the existing values of parameters and which of the goals aren't. The goal program has been run with both uniform and variable demand values in all the periods. In the absence of real data, all the parameter values considered for this research have been assumed. The major contributions of the research are as follows: each member of the supply chain has its own individual objective and the related constraints which is a more realistic approach, the model considers multiple products, and the model considers operations at the product, subassembly, part, and material levels. All the above contributions make this research as the first approach of its kind which has never been attempted (based on literature reviewed) and the goal programming methodology used is also a well accepted approach among all the multi-objective programming approaches. Results show the effect of varying the priority/weight associated with a goal. Results also show that values of the deviational variables (positive or negative) help a decision maker to analyze the model. The goal programming approach is considered to be the most effective approach in terms of defining the mathematical model, analyzing the output, and modifying the model (if needed).

This book was released on 2000-03-23 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The managed flow of goods and information from raw material to final sale also known as a "supply chain" affects everythingâ€"from the U.S. gross domestic product to where you can buy your jeans. The nature of a company's supply chain has a significant effect on its success or failureâ€"as in the success of Dell Computer's make-to-order system and the failure of General Motor's vertical integration during the 1998 United Auto Workers strike. Supply Chain Integration looks at this crucial component of business at a time when product design, manufacture, and delivery are changing radically and globally. This book explores the benefits of continuously improving the relationship between the firm, its suppliers, and its customers to ensure the highest added value. This book identifies the state-of-the-art developments that contribute to the success of vertical tiers of suppliers and relates these developments to the capabilities that small and medium-sized manufacturers must have to be viable participants in this system. Strategies for attaining these capabilities through manufacturing extension centers and other technical assistance providers at the national, state, and local level are suggested. This book identifies action steps for small and medium-sized manufacturersâ€"the "seed corn" of business start-up and developmentâ€"to improve supply chain management. The book examines supply chain models from consultant firms, universities, manufacturers, and associations. Topics include the roles of suppliers and other supply chain participants, the rise of outsourcing, the importance of information management, the natural tension between buyer and seller, sources of assistance to small and medium-sized firms, and a host of other issues. Supply Chain Integration will be of interest to industry policymakers, economists, researchers, business leaders, and forward-thinking executives.
