The model describes the manufacturing processes and the corresponding equipment by their capabilities and performance. For example, machine tool capabilities includes the number of axes, the axis travel, the achievable accuracy, repeatability, and spindle motor power. This process information is required for the feasibility and manufacturability evaluation of a product design. The manufacturing plant model also describes the manufacturing management and design functions of the plant and the financial health of the corporate parent. Such information is useful for prequalifying a plant to participate in a virtual enterprise.
Figure describes the structure of the manufacturing plant model.
An in-depth description can be found in Candadai et al. The plant model development included the input of manufacturing firms, who suggested important prequalification criteria and process capability attributes. A process information model, however, is a database that contains plant independent process information critical for process planning. Such information, typically found in manufacturing handbooks, describes universal process capabilities, material-process compatibilities, and recommended production quantities. These models are used for assessing the feasibility and manufacturability of a product design.
