Abstract. Operations management deals with the design and management of products, processes, services and supply chains. Supply chains integration and manufacturing operations management can benefit highly from the use of webbased technologies by ensuring a smooth connectivity and interoperability between software components, especially in a real-time basis by reinforcing the use of multi-agents combined with web service based technologies. The more the accurate and dynamic is the update of the information in a company, the more the enhancement of the manufacturing decision-making process will be over the whole company's performance. Moreover, web-based technologies combined with multi-agents provide gains in agility and flexibility for building versatile supply chain management systems. Therefore, the purpose of this paper is to present and propose an integrated web-based framework to cover the main integration requirement from a system point of view, this within the main purpose of supporting the supply chain management and operation in supply chain environments. For this purpose, an automotive supply chain industry is considered to illustrate the applicability of this proposed framework.
