PROBLEM TO BE SOLVED: To decrease load of an operator managing the manufacturing process of products by providing a process hysteresis data judging means for judging the state of the process hysteresis of the product having the target number on the basis of the process hysteresis data. SOLUTION: A file server(FS) 1 obtains the number of the process by the initially selected input item, refers to a product process hysteresis master table of the input product number, and retrieves the number of the process of the finished product process. The product hysteresis master table for holding and renewing the process number of the finished manufacturing process in relation to all product numbers is stored in the file server 1. The data are sequentially inputted by a manufacturing device connected to a data base managing computer 2 and a network 6. The optional data item is selected by handy terminals(HT) 5, the number of the product subjected to processing is input, and enquiry is performed to the FS. The result is displayed on the HT and helps an operator to judge. |
