Abstract
A computer system is so configured as to be divided into a control system which should have high reliability and high responsiveness and an information system which does not access the control system. They are connected via a transmission path (transmission path of control system and transmission path of information system). Centralized management of development and maintenance is performed from a software maintenance system. In development and maintenance of software, management according to the feature of each software such as processing contents of each software, demanded reliability, and version up frequency is performed from a maintenance system for exclusive use by using a transmission path of information system. Thereby, development and maintenance having high reliability and expandability is realized.
