It was 1. When the quality control system goes down, the input terminal device cannot be connected to the server, so the input file of the server cannot be accessed, and the operator writes down the quality information to be input in a handwritten memo. After the quality control system was restored, the quality information that was written down had to be input again from the input terminal device. 2. Also, since different operators independently keyed in the quality information from multiple input terminal devices, the quality information for the same item was mistakenly keyed in from the same inspection report, causing an overlap of inputs. There were times when it happened. 3. Furthermore, because an individual information network was formed between the assembly process, the completion inspection process, and the production control department of the factory, the individual information input in these processes and departments is managed consistently for each vehicle. I couldn't. In view of the above-mentioned problems, it is an object of the present invention to provide a quality information network management method capable of efficiently and constantly processing quality information from a large number of terminal devices in a quality management system.
