Steel fabrication is a complex process, which encompasses product uniqueness, a high product mix, and a number of activities involving a variety of equipment and labor disciplines. The steel fabrication industry needs advanced tools and techniques in order to estimate, plan, and control fabrication shops. This paper proposes a system for building virtual fabrication shop models capable of estimating, scheduling, and analyze production. The system defines conceptual models for product, process, and the fabrication facility itself. It offers tools, such as product modeling, process modeling and planning, and a special purpose facility modeling tool, which allow users to implement these conceptual models. Modeling enhancements have enabled a more accurate modeling of machine and labor productivity, as well as better management of shop production rules. The modeling capability of the developed system is demonstrated through a case study.
