Abstract

PROBLEM TO BE SOLVED: To efficiently grasp the physical distribution and to predict the necessary number of personnels by referring to a man-hour master table stored based on registered data and calculating evaluation supporting data by each part. SOLUTION: A man-hour master table being a man-hour list at each operation unit is previously registered for an evaluation supporting device. A man-hour master table is divided into standard, post-processing, reloading and transportation along the supplying job of parts to an assembling line. In addition the items of them are sorted to concrete operation contents and time (man-hour) (a) to (an) necessary for the operation is registered as the reference time of each operation content. An operator inputs each item of an evaluation sheet by each part based on real operation attached to a part to be supplied for the assembling line (or by supposing real operation). The evaluation supporting device calculates the number of personnels necessary for preparing an evaluating result sheet by referring to the man-hour master table based on data inputted by the operator.
