The dynamic characteristics of engineered-to-order (ETO) environments are in conflict with the basic assumptions of Manufacturing Resource Planning (MRP) systems, which makes MRP based manufacturing planning systems fail to meet the needs of ETO companies. ETO environments are complex and require sophisticated planning techniques. In fact, the shortcomings of planning and scheduling systems are exacerbating the ability of ETO companies to reduce manufacturing cycle times. This thesis presents an overview of ETO environments and related manufacturing planning and scheduling systems. The reasons for the failure of present MRP systems to address ETO environments are discussed along with an analysis of the planning systems of real companies. A new framework for manufacturing planning and scheduling in ETO environments is proposed. It addresses the importance of coordinating planning and scheduling among engineering, material procurement and the shop floor. It incorporates finite capacity scheduling into MRP systems to overcome load fluctuations. It also has scheduling mechanisms to address the dynamic nature of ETO environments.
