This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, Supply Chain Management (SCM) is one of the most important and complex issues for automakers in the world. The main objectives of this research were to investigate the factors that predict strategic performance of supply chain by doing quantitative research at Iran Khodro Company (IKCO) in Iran. Based on supply chain theories, strategic performance of supply chain was predicted by Information Technology (IT), Organizational Learning (OL), and Product Innovation (PRI) in our research at the first time in an automotive company. Stratified random sampling was used to determine the sample size. Accordingly, 250 questionnaires were distributed among experts and supply chain specialists at IKCO. According to Supplying Automotive Parts Company (SPSC) variable as the main dependent variable, Path Analysis (PA) technique was used to explore casual relationships among variables using multiple regression analysis in SPSS. The Confirmatory Factor Analysis (CFA) was utilized based on Maximum Likelihood (ML) analysis of normality, outliers, composite reliability, and validity to test hypotheses by using AMOS. PA, measurement model, and structural model were analyzed in order to examine the conceptual model. The results from multiple regression, path analysis, and Structural Equation Modeling (SEM) were same. Thus, all hypotheses were supported by SPSS and SEM analyses. The findings of the study are discussed in detail.

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.

This book was released on 2018-12-12 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: The exponential increase in the development of technology coupled with the customers’ immense desire to possess the newest technological products makes for truncated product lifespans, which instigates a substantial upsurge in their rate of disposal. Attempts have been made to establish specialized product recovery facilities with the intention of diminishing the volume of accumulated waste delivered to landfills using product recovery procedure such as remanufacturing. The economic benefits produced by remanufacturing also portray the role of product recovery in a more attractive light. The quality of a remanufactured product is uncertain for some consumers. Therefore, these consumers possess insecurities in deciding whether or not the remanufactured products will render the same expected performance. This ambiguity regarding a remanufactured product could possibly result in the consumer deciding against its purchase. With such consumer apprehension, remanufacturers often seek market mechanisms that provide reassurance as to the stable durability that these products still maintain. One strategy that the remanufacturers often use is the utilization of the premise of offering product warranties with preventive maintenance on their products. This book is concerned with the practice and theory of warranty management and preventive maintenance, particularly in relation to remanufactured products’ warranties. Models developed in this book can be used for making the right decisions in offering renewable, nonrenewable, one and two dimensional warranty policies, and for managerial decision in considering maintenance contracts or outsourcing maintenance for remanufactured components and products. Features Discusses a variety of warranty policies and preventive maintenance of remanufactured products (first book to do so) Presents mathematical models and applications for warranty policies using examples and simulation results Considers cost and optimization problems from the remanufacturer's and buyer's points of views Provides a foundation for academicians interested in building models in the area of warranty and preventive maintenance analysis of remanufactured products Offers the essential methodology needed by practitioners involved with warranty and preventive maintenance analysis, along with extensive references for further research

Download or read book Modelling and Optimization of Closed loop Supply Chain Networks Considering Product Recovery written by Yongtong Chen and published by . This book was released on 2016 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: To further inspect the process of product recovery in a CLSC, a multi-period decision model considering uncertainties is established. This model simulates the process of product refurbishment in a CLSC and discusses uncertainties in end of life products collection, including customer demand uncertainty, returned product quality uncertainty and returned product quantity uncertainty. In the literature, few research studies have focused on the process of returned products refurbishment in closed-loop supply chain networks. Considering the deepening crisis caused by abandoned end of life products, especially electronic waste, it is important to propose a model like this. This proposed model structures the end of life products refurbishment process and provides decision supports for end of life products collection, considering the uncertainties in both quantity and quality. In this decision model, a two-layer fuzzy controller embedded with a quality indicator is developed. This proposed method effectively deals with the uncertainties of both supplies and demands in multi-period production planning of returned products refurbishment. A simulation system based on this model is implemented, which proves the effectiveness of the proposed fuzzy controller. It also proves the efficiency of the quality indicator dealing with the quality uncertainty. The developed simulation system provides decision support for end of life products collection for responsible manufacturers. Additionally, the increasing profits of end of life products refurbishment encourage product recovery to some extent. The originality and significance of this research lies in the proposed models and algorithms. This research contributes to the body of knowledge by: (i) Establishing a closed-loop supply chain model with product recovery, which filling the gap of considering multiple materials with different quality in CLSC networks, (ii) developing a two-stage priority based encoding Genetic Algorithm to reinforce the genetic searching ability in tackling NP-hard problems in closed-loop supply chain, (iii) establishing a multi-period product refurbishment model in closed-loop supply chain, which fill the gap of describing product refurbishment process considering uncertainties, (iv) developing a two-layer fuzzy controller embedded with a quality indicator to deal with uncertainties effectively in product refurbishment, and (v) implementing a simulation system to simulate the process of product refurbishment, which providing decision supports for end of life product collection and in turn mitigate environmental problems. This research provides an important means to better understand the product recovery in closed-loop supply chain and contributes significantly to the further improvement of the performance of end of life product collection.

Download or read book Capturing Value from Decentralized Supply Chain with Third Party Reverse Logistics written by Yertai Tanai and published by . This book was released on 2016 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: As competition in the global market continues to grow and customers are becoming more environmentally as well as cost conscious, recent trends in retail practices attest to the attention and resources devoted to the returns in supply chains. Topping the list is the economic incentive to reap as much value as possible from returns. With the growth of an internet consumer base, vigorous competition and the advance of online sales regardless of product type, size and locations, many firms provide generous return policies. This has caused a significant increase in the volume of reverse flows and therefore great potential for value recovery from returns. According to the National Retail Federation, the value of merchandise returned amounted to $260.5 billion in 2015. Hence, ways of improving the performance of a supply chain through effectively and efficiently closing the loop have received considerable attention both from academic researchers and industry practitioners over the past two decades. One way to recoup returns value as quickly as possible is to decentralize reverse logistics functions to third party reverse logistics providers (3PRLP). Outsourcing to a 3PRLP allows a firm to gain a state-of-the-art reverse logistics program immediately thereby avoiding the capital investment and start up delay required to implement an in-house RL program. This dissertation proposes two models of a Closed-Loop Supply Chain (CLSC) with independent 3PRLP for returns processing. The first model presents a CLSC where demand is generated by a stochastic process. A fraction of the units that are initially sold are returned by the consumers for a full refund in every period. We model the forward flow interaction between the supplier, the retailer and 3PRLP by a widely accepted control policy that is lot size-reorder point inventory policy, which is detailed by the Markov process. We further propose a queuing network to capture reverse flow activities of the 3PRLP, which consists of customer decision delay and each of the 3PRLP activities. We characterize the expected profits for both firms and derive the effects of key parameters through set of numerical examples. The results of optimization based on numerical examples indicate that both firms' benefits from processing returns increase with an increasing returns rate. This is due to fact that the retailer captures more profits through selling processed returns at the price of new product. The 3PRLP unambiguously earns more profit from increasing product returns since the fee from processing returns is sole source of revenue. Furthermore, the directions of effects of changes in the holding cost are similar for both the retailer and 3PRLP. However, the magnitude of effects of the same parameter are quite opposite. Interestingly, the retailer's profit appears to be more sensitive to the holding cost than that of the 3PRLP's profit. The second model analyzes coordination issues between a retailer and a 3PRLP to manage product returns. We formulate the returns processing capacity of a 3PRLP as a two-input production function where there is only one variable input. Crucially, this implies that the 3PRLP's short run marginal cost is strictly increasing. This key feature of the 3PRLP's short run cost function motivates two supply chain interaction scenarios. In an uncoordinated supply chain, the retailer acts as a market leader who makes a take-it-or-leave-it fee and quantity of returns offers to the 3PRLP. With increasing marginal cost of returns processing and retailer market power, the quantity of returns processed is inefficiently low due to a standard monopsony argument. In a coordinated supply chain, the retailer and the 3PRLP jointly decide on the returns quantity to be processed in order to maximize the total profit for the supply chain. An appealing approach to model how the benefit to coordination is shared between the two firms is Nash bargaining. Accordingly, we characterize the Nash bargaining solution with asymmetric bargaining powers, assuming that the disagreement payoffs are given by the uncoordinated supply chain profit levels. The underlying model is one where the retailer and the 3PRLP negotiate the quantity of returns and the per unit fee, while both recognize that if they fail to reach an agreement, the retailer is poised to make a unilateral offer as in the uncoordinated case.
