At present, "Multi combination + differentiated management " has become a effective commercial expansion path of development. According to reporter statistics, including the Parkson shopping center, Guiyou Plaza, Blue Island, Cuiwei Plaza, Xidan shopping mall, Dangdai shopping mall , Wangfujing department store ,

The Architecture and Operation Mode of Virtual Supply Chain

Virtual supply chain, as a modern collaborative mode of enterprises, is important to decrease the cost and improve the efficiency and the quality of supply chains, and to satisfy customers. Based on the analysis of the conception and characteristics of the virtual supply chain, the architecture of virtual supply chain is built, and corresponding objects, tasks, information and technologies are described. Three operation modes-Order-driven, manufacturer-centered, and retailer-centered are researched. As a case, virtual supply chain is applied in the electronic commerce and networked customization system of ceramic products.

A Web Service Framework for Environmental and Carbon Footprint Monitoring in Construction Supply Chains

With the growing environmental concerns, green supply chain management （GSCM） is gaining significant attention in the construction industry. Tracking and monitoring the environmental effects brought forth by the participating members along a supply chain is important to GSCM. The GreenSCOR model developed by the Supply Chain Council provides a generic framework for measuring the total carbon footprint and environmental footprint in a supply chain. The model is based on the Supply Chain Operations Reference （SCOR） model, which represents a supply chain network in a hierarchically structured manner. This paper describes the GreenSCOR framework and its potential application to the construction industry. This paper also presents a web services approach to incorporate the GreenSCOR model to the implementation of collaborative information systems. Each process element in the SCOR model is represented and delivered as individual web service units, which can be reused and integrated using standard web services technologies. The service units are combined and managed in a prototype web service collaborative framework, called SC Collaborator, which is designed and developed for supporting construction supply chain management. An illustrative example is presented to demonstrate the implementation of the GreenSCOR-based SC Collaborator framework.

Reactive and Robust Planning of Moroccan Citrus Chain Based on Multi-agent System and Performance Indicators

As part of improving services done for various clients in all Moroccan areas, Moroccan exportation group of fruits and vegetables in collaboration with their packaging units and producers, tends to cooperate in order to face with international competitiveness. Indeed, the complexity of networks of partners has led policy-makers to implement new techniques and tools to help control different processes. For this reason, the implementation of a permanent monitoring of different operations ranging from production, packaging, and distribution of perishable products has become paramount. This article aims to propose a model of multi-agent citrus supply chain, based on indicators for monitoring and evaluation of performance of its logistics systems, in order to build a new independent, robust and responsive chain, and to optimize and control the flow of materials and information between the different actors and stakeholders of the chain.

AN IMPROVED GENETIC ALGORITHM FOR SEARCHING OPTIMAL PARAMETERS IN n-DIMENSIONAL SPACE

An improved genetic algorithm for searching optimal parameters in n-dimensional space is presented, which encodes movement direction and distance and searches from coarse to precise. The algorithm can realize global optimization and improve the search efficiency, and can be applied effectively in industrial optimization, data mining and pattern recognition.

JYPB2.0—A new composition adjust-ment processing system of metal melting

The new system contains all the independent variables, setting the ultimate objective function groups,installing the complete operating program chain and establishing the accurate mathematical model. The new systemproduces the ultimate objective function group- Optimum Proportion Scheme through the processing of the elevenoperating main programs such as Optimization Program, etc. and revising of three operating auxiliary programssuch as Elimination Program, etc. which is locked by the intermediary objective function group. The setting of thecomplete database system provides the full-service for the customers' smelting production. It is generally applicablefor all the varieties of alloys and raw materials. Its customized features can fulfill the actual needs of users. These arethe advantages of the new composition adjustment processing system of metal melting- JYPB2.0.

OPTIMAL OPERATIONAL DECISIONS WHEN A MANUFACTURER OFFERS TRADE CREDIT TO HIS RETAILER

In this paper, we develop models to determine operational and financial decisions of a supply chain under the condition that the retailer faces a financial constraint and the manufacturer can offer trade credit to assist the retailer. We first study the case where the retailer is risk-neutral, and derive the optimal ordering and financial decisions. Then, the case where the retailer is risk-averse （downside risk） is studied and-the effects of the risk on the retailer and manufacturer＇s operational and financial decisions are discussed. Finally, numerical examples are provided to conduct managerial analysis.
