A generic analytical target cascading optimization system for decentralized supply chain configuration over supply chain grid
ABSTRACT While centralized supply chain configuration (SCC) adopts an integrated decision model solved by an all-in-one decision method, decentralized SCC normally allows constituent enterprises to employ distributed decision models which are coordinated through a decomposition method to achieve an overall solution. Decentralized SCC paradigm could offer various contemporary advantages such as individual suppliers’ decision right protection and overall decision efficiency enhancement. This paper proposes an optimization system, atcPortal, to practically enable such a decentralized SCC process. Individual suppliers convert their local decision support systems into decision web services to form a distributed open-standard SCC service platform, called supply chain grid (SCG) in this paper. As a decomposition-based optimization method, analytical target cascading (ATC) is the mechanism for atcPortal to coordinate these web services through three phases of service searching, service-based ATC problem definition, and service-oriented ATC execution. atcPortal is a generic and extensible web portal in the sense that ATC accommodates a variety of decentralized SCC decision structures without confining the local decision models of individual enterprises. Finally, the usage of atcPortal is demonstrated through a typical decentralized SCC problem.

ABSTRACT: In order to guarantee the overall production performance of the multiple departments in an air-condition production industry, multidisciplinary design optimization model for production system is established based on the multi-agent technology. Local operation models for departments of plan, marketing, sales, purchasing, as well as production and warehouse are formulated into individual agents, and their respective local objectives are collectively formulated into a multi-objective optimization problem. Considering the coupling effects among the correlated agents, the optimization process is carried out based on self-adaptive chaos immune optimization algorithm with mutative scale. The numerical results indicate that the proposed multi-agent optimization model truly reflects the actual situations of the air-condition production system. The proposed multi-agent based multidisciplinary design optimization method can help companies enhance their income ratio and profit by about 33% and 36%, respectively, and reduce the total cost by about 1.8%.J.

ABSTRACT: In order to analyse product–service performance (PSP) during product–service systems' (PSSs) running time, a PSP evaluation method is proposed. Interrelationship between a PSS's provider and accepter is defined as product–service relationship (PSR). Concepts of product–service network and product–service chain are put forward to describe interrelationship among PSRs from different perspectives. The concept of PSP is proposed to evaluate interrelationship among PSR. Detailed evaluation indexes are designed to measure the five factors of PSP, including time, quality, cost, stability and reliability. A case study is provided to test the validity and efficiency of the evaluation model of PSP. The analysis results show that the evaluation model can make good efforts in benefiting product–service platform's running, monitoring and optimising.International Journal of Computer Integrated Manufacturing 01/2012; 25:150-157. · 0.94 Impact Factor

ABSTRACT: Radio frequency identification (RFID) technology enables real-time traceability, visibility and interoperability of manufacturing resources and thus improves the performance of shop-floor planning, execution and control. However, a big challenge faced by manufacturers now is to deal with various RFID/Auto-ID technologies which are necessary in different production situations yet entailing different development technologies. This paper presents an innovative all-in-one Smart Gateway technology for capturing real-time production data from various manufacturing resources attached to different types of RFID/Auto-ID devices. Each of such manufacturing resources forms a smart object (SO) while agent concept is introduced for encapsulating the heterogeneous SOs. Taking advantages of web services, agents are developed and managed in a standard way following service-oriented architecture (SOA). Smart objects and agents are dynamically deployed and reconfigured at a Smart Gateway in a ‘plug and play’ fashion. The joint work among smart objects is governed by an agent-based workflow management (AWFM) mechanism. The proposed framework and core technologies are demonstrated by an assembly workstation case where a Smart Gateway is deployed for defining, configuring and executing assembly operations on a real-time basis.International Journal of Production Research - INT J PROD RES. 01/2011; 49(5):1337-1352.
