This chapter discusses various business process supply-chain models and emphasizes the need for organizations to apply CRM concepts and to integrate the Internet within the functions of the supply chain in order to be able to gain good customer expectations in the era of e-commerce. This chapter outlines a framework for developing a Web-based supply chain integrating model based on SCOR and key features of CPFR, and attempts to link this model with Business Process Reengineering, and with traditional productivity improvement programs. The development of a Web site at two levels is suggested. The first level is within the public domain and the other is limited to supply chain partners. The chapter incorporates fuzzy set theory into the dynamic of production scheduling to allow the integrating model to deal with vague constraints, and to enable conflicting multi-criteria objectives to be managed effectively in the production environment.
