Analyzing Remanufacturability of Mobile Phones using DEMATEL Approach

The use of mobile phone has increased at a surprisingly high rate over these two decades. For many people, especially young generations, mobile phone has even become a primary need. As a consequence, the production of mobile phone has increased significantly and followed immediately by the disposal, as a result of its short life-cycle nature. Recently, there are substantial initiatives proposed in order to mitigate the effect of e-waste to the environment. Remanufacturing is one of recovery processes that could extend product�s useful life and provide a circular life-cycle instead of linear. However, there are many factors that can affect the success of remanufacturing engagement, and specifically remanufacturability of a mobile phone. There are numerous considerations of remanufacturability with regards to the short life-cycle nature of mobile phone, and these factors can be qualitative or quantitative, with conflicting potentials, and some of them may be uncertain. In this study, we use Decision Making Trial and Evaluation Laboratory (DEMATEL) approach to identify the interrelationship among the factors and analyze those results to identify the prominent factors. Furthermore, an influential-relation map is provided to support visualization for managerial implications. The case results show that innovation-rate and obsolescence are factors that give highest impact while source-of-returns and pricing are factors that receive highest effects from other factors. Also, acquisition-of-used-product, pricing, and market-size are dominant factors as they significantly affect and affected by others

The Conceptual Framework of Information Technology Adoption Decision-making in a Closed-loop Supply Chain

Closed-loop supply chain has gained a significant attention during the recent decades since there is an increased awareness toward sustainable development. However, the implementation of closed-loop supply chain is confronted with numerous barriers and challenges due to uncertainties in input as well as in process. In contrast to manufacturing process where the input is mostly homogeneous raw material, the reverse chains input comes from products end-of-use or end-of-life; therefore the timing, quality and quantity are uncertain. The recovery process also brings other challenges due to various quality grades of the product returns and various recovery options. On the other hand, information technology has been studied extensively in relation to supply chain management. Most of the works show that the use of information technology could enhance supply chain performance. However, the study on the importance of information technology in closed-loop supply chain is still limited. In this paper, we discuss the role of information technology and then propose a conceptual framework of decision making in adopting IT in closed-loop supply chain management

Knowledge Sharing in Closed-Loop Supply Chain Management

In the recent decades, closed-loop supply chain has been studied extensively due to the increased concern on sustainable development. It integrates forward and reverse flows where the collaborative supply chain takes place. Knowledge management is one important part of an organization that can improve the effectiveness of the processes within the organization. Knowledge sharing is significant in a collaborative supply chain since it affects the organizational performance and competitive advantage. The complexity in closed-loop supply chain can be managed better by encouraging knowledge sharing among the supply chain members. This paper presents a conceptual framework to implement knowledge sharing in a closed-loop supply chain management, for improving the CLSC members’ performance. The success factors have been identified, and a framework has been presented, it consists of knowledge flows, management aspect and socio-technical aspec

Challenges in Quality Assurance: A Ten-Year Journey

Academic quality is defined as the equivalent to academic standards related to student learning outcomes, which consist of specific levels of knowledge, skills, and abilities achieved by students participating in a program. The achievement of academic standards is accommodated by implementing both internal and external quality assurance practices. Internal quality assurance refers to policies and practices used by the higher education institutions to monitor and improve the quality of their education, while external quality assurance refers to policies and practices set up by external parties to assure the quality of higher education institutions and programs. Petra Christian University has built and implemented its internal quality assurance since 2009 based on its unique quality culture. After its ten-year journey and the achievements that Petra Christian University has reached in 2019, the Industrial Revolution 4.0 and Society 5.0 are challenges ahead that Petra Christian University has to face

Pricing and Warranty Level Decisions for New and Remanufactured Short Life-Cycle Products

Remanufacturing has become more prominent as a recovery process to mitigate the massive disposal of short life-cycle product at its end-of-use. However, remanufactured product is often perceived to be inferior to new product, and it has lower value in consumer’s willingness to pay. To increase the perceived quality of the remanufactured product, manufacturer offers a warranty, since one of the three roles possessed in warranty is being a signal to product reliability. This paper studies the pricing decisions and warranty level decision for new and remanufactured products in a closed-loop supply chain consists of a manufacturer and a retailer. The optimization modeling is performed under Stackelberg game with manufacturer as the leader. We found that higher expansion effectiveness coefficient would increase the supply chain profit. Also, there is an interval of demand’s speed of change, where the total profit would be at its highest. The optimum warranty level can be achieved regardless the initial warranty level set at the beginning of retailer’s optimization. Furthermore, the remanufactured product’s wholesale and retail prices are influenced by the expansion effectiveness coefficient

Drivers and Barriers of Mobile Phone Remanufacturing Business in Indonesia: Perspectives of Retailers

Remanufacturing is deemed to be effective in reducing WEEE. Existing studies on remanufacturing mostly focus on operational issues, product acquisition, and pricing. However, some doubts about remanufacturing business arise in developing countries, where there is less regulation on remanufacturing and less environmental awareness. This study aims to investigate the prospects of remanufacturing business from the retailers' perspectives through in-depth interviews on three retailers in Surabaya, Indonesia. The main drivers for mobile phone remanufacturing business are its affordable and competitive price, big demand for popular mobile phones and high-end mobile phone, the opportunity for specification upgrade, and its suitability with the needs of Indonesian people. The main barriers for remanufacturing business are the possibility for cannibalizing new mobile phones' market share, the uncertainty of core supply, discontinuity of replacement part supply, lack of product knowledge among consumers and retailers, hesitation of retailers to sell remanufactured products, and lack of strict and clear regulations about remanufacturing business. Findings of this study provide insights to prospective mobile phone remanufacturers of what needs to be tackled to start a prosperous business. On the theoretical side, it provides complementary knowledge to existing studies that have been conducted mostly on countries that have higher environmental awareness

The Effect of Product Quality on the Pricing of New and Remanufactured Short Life-cycle Product

Remanufacturing is one of the recovery process that has become significant among many attempts to mitigate the landfill exhaustion, especially from mountain of wastes that come from short life-cycle products disposal. However, remanufactured product are often perceived to have lower quality compared to the new one. There are misconception about remanufactured product and lack of knowledge about its characteristics. On the other hand, several studies show that price and product quality have positive relationship. This paper investigates the effect of product’s perceived quality on the pricing decision, to maximize the profit of the retailer and the manufacturer. We develop pricing decision model for new and remanufactured short life-cycle product in a closed-loop supply chain consists of a manufacturer and a retailer, where the manufacturer is a Stackleberg leader. We find that lower product’s perceived quality would decrease the retail and wholesale prices of new and remanufactured products, but does not affect the new product’s sales volume significantly. Also, the speed of change of demand influences the optimum total profit
