Dual channel closed-loop supply chain coordination with a reward-driven remanufacturing policy
Saha, S.,Sarmah, S.P.,Moon, Ilkyeong Institution of Production Engineers 2016 International journal of production research Vol.54 No.5
<P>This paper investigates a reward-driven policy, employed in a closed-loop supply chain (CLSC), for acquiring used products earmarked for remanufacture. Under the examined model, a single manufacturer sells products through a retailer as well as directly to end users in a forward supply chain. In the reverse supply chain, three different modes of collection are employed to capture used products for remanufacture: they are through a third party, directly by the manufacturer and from the retailer. Mathematical models for both non-cooperative and centralised scenarios are developed to characterise the pricing decisions and remanufacturing strategies that indicate individual and overall supply chain performance. Optimality of all the proposed models is examined with theory. To coordinate and achieve a win-win outcome for channel members, we proposed a three-way discount mechanism for the manufacturer. Extended numerical investigation provides insights on ways to manage an efficient reward-driven CLSC in a dual-channel environment.</P>

BPM-based integration of supply chain process modeling, executing and monitoring
Bae, Hyerim,Seo, Yongwon Institution of Production Engineers 2007 International journal of production research Vol.45 No.11
<P> Due to increased competition in business environments, many companies implement Supply Chain Management (SCM), which utilizes advanced information technologies. Since the execution of the Supply Chain Process (SCP) requires interaction and information sharing among multiple organizations, there have been efforts to apply Business Process Management (BPM) techniques to SCM implementation. Whereas previous research has focused mainly on automated execution of the SCP, effective SCM requires the integrated lifecycle management of SCP that includes modeling, execution, and monitoring. Thus, in this research, we develop, based on the BPM system, an integrated architecture to support modeling, execution and monitoring of SCP. To model the SCP, we propose to use Business Process Execution Language (BPEL), which facilitates easy process sharing among supply chain members who adopt heterogeneous information systems. Since SCM decisions require complex analytical calculations concerning multiple different companies, it is necessary to separate the process logic and the decision algorithm. Thus, we developed an SCP execution structure in which the decision algorithm is implemented as an agent that is invoked using Web services. While BPM enables process monitoring, the multi-organizational environment considered here involves the important issue of the setting and controlling of access levels of each company's process information to be monitored. To address this problem, we propose a role-based supply chain process monitoring (RSCPM) model. A prototype system is implemented.</P>
