BPR(Business Process Reengineering) is a hot topic in industry today. Many enterprises see BPR as a means to attaining remarkable competitive advantages. For BPR, simulation modeling can be used to not only analyze an as-is model of the existing business process but also assess the potential value and feasibility of to-be models. There are some modeling and simulation tools available which can be used to support BPR. But this tools is restricted to analysis and redesign of the work flow. Little attention is paid to the organization of people and its roles.
This paper presents a new method of business process simulation modeling and analysis exclusively designed to support BPR based on the concepts of roles and customer-supplier chains. The proposed modeling was derived from object-oriented modeling and queueing model. This method allows for tracking people and their roles affected by reengineering the business process because it enables one to analyze and to evaluate not only work flow, but roles that are part of the flow. This paper also suggests a systematic way to construct simulation models and conduct simulations easily and efficiently.
