DRAWING DESIGN/PRODUCTION PROCESS DESIGN SYSTEM

PURPOSE:To design a drawing while considering production conditions and economic efficiency by allowing a drawing design system body to extract knowledge relating at least to the production conditions of drawing features for design from a knowledge base storing part to be used for the process design of a production process design system body at the time of generating a production condition checking instruction. CONSTITUTION:In the case of the referring the production conditions of a machine, tool, etc., to practically execute the working of the features of a drawing, the drawing design system body 20 extracts necessary knowledge from the knowledge base storing part 40 storing knowledge relating to the process design in accordance with operator's operation. In case the of deciding the economic efficiency of the drawing information plan at the time of ending the whole drawing design, the body 20 applies the plant to the production proc ess design system body 30 in accordance with operator's operation and executes process design based upon the drawing information plan and forms plural proc ess sequence guides and a process sequence determining means included in either one of the system bodies determines an optimum process sequence plan from the process sequence plans on the basis of an inputted evaluation function.
