Abstract
A manufacturing planning system has lead time estimating function, MRP executing function, work demand calculating function, problem analyzing function, capacity adjusting function, product completion data adjusting function, and alternative shop designating function for planning a production schedule by calculating successively lead time in consideration of amount of work demanded and capacity for production, analyzing problems in the production schedule and performing relevant adjustments for solving the problems. An on-line display function is provided for simultaneous display of the problems and load/capacity states of production shops in association with solution of the problems and various adjustment together with the results thereof.
