<p>PROBLEM TO BE SOLVED: To provide a production history information managing device capable of evaluating the bottle neck of a production line by managing an inventory in process which is present on a production line in a real time. SOLUTION: At the time of receiving the identification information of a product read by the bar code readers of terminals T1-T9 arranged in each process, a production history information preparing part 53 calculates a working time in each process, and allows a storage part 52 to store the information. The storage part 52 stores prescribed data inputted from an input part 51 in addition to the working time in each process. An arithmetic part 55 calculates an each process inventory in process sum, production costs, and material costs or the like from the working time in each process and the prescribed data stored in the storage part 52, and allows a display part 55 and a printing part 57 to output them. Therefore, it is possible to manage the inventory in process in a real time, and to evaluate the bottle neck of the production line.</p> |
