This paper designs a mathematical model for supply chain network design problem including plants, distributors and customers in fuzzy environment. Each plant and distributor has several levels capacities. A multi-mode demand strategy is considered for the customers where only one of the modes is to be selected for each customer. Considering the acceptance degree of fuzzy constraints violated, a...

This paper presents a competitive supply chain network design problem in which one, two, or three supply chains are planning to enter the price-dependent markets simultaneously in uncertain environments and decide to set the prices and shape their networks. The chains produce competitive products either identical or highly substitutable. Fuzzy multi-level mixed integer programming is used to mo...

Global supply chains and worldwide spread subsidiaries are a topic for both huge enterprises as well as for small and medium sized enterprises. The challenge lies in the right allocation of functions and competencies within the global production network and in their coordination and integration in order to gain the desired outcome and to reach the objectives tied to the networks. In this contex...

This paper emphasizes on the enhancement of web-based selling technology for complex products. The approach of the EC-funded CAWICOMS1 project is twofold: provision of technologies both for customeradaptive Web-interfaces for the configuration of mass-customized products as well as for the integration of configuration systems along the supply-chain. Within this paper we first motivate the deman...

Within CAWICOMS a configuration workbench for customisable products and services will be developed which will have the following advantages versus current commercially available configuration technology: It will automate over the Web the skills of salespersons by developing adaptation and personalisation technology for inclusion in Web based configurators. The interaction with the user will be ...

having a comprehensive evaluation model with reliable data is useful to improve performance of supply chain. in this paper, according to the nature of supply chain, a model is presented that able to evaluate the performance of the supply chain by a network data envelopment analysis model and by using the financial, intellectual capital (knowledge base), collaboration and responsiveness factors ...

With the expansion of network services, large-scale networks have progressively become common. The status changes rapidly in response to customer needs and configuration changes, so are also very frequent. However, no matter what must ensure correct conditions, such as isolating tenants from each other or guaranteeing essential services. Once occur, it is necessary verify after-changed network....
