Market-driven rapid response manufacturing demands manufacturing enterprises to increase their agility and robustness. This leads to more effective and efficient organization, management, planning and control of manufacturing resources in the manufacturing enterprises. In the paper, object-oriented method is adopted and UML is used to establish a manufacturing resource model. Then, all evaluation indices and corresponding hierarchical structure are established based on AHP. Then, the problem of rough capability estimation for Make-to-Order enterprises is described and discussed that deal with production orders of different delivery dates based on limited manufacturing resources. A rough production capability estimation system for Make-to-Order enterprises under limited manufacturing resources constraints is developed on Delphi 7 platform. The approach can be used to rapidly judge whether an enterprise has the capabilities needed to finish production orders on time, and to estimate a new order’s delivery date. The study of the paper lays the foundation for the future research of supply chain and distributed manufacturing.
