In order to improve working efficiency,recede error possibility,strengthen the management of operation order sheet,this paper analyzed the operation order-sheet computer generating system and the reasoning mechanism of machine operation tickets,research and development of the system based on network-structure and switch controlling logic.

A novel method based on the switching logic to represent power system structural configuration,operating condition and operation activities for expert system applications is developed.

According to the problem of signal route allocation and management in automatic test system,this paper established route model based on the thought of sharing the information with other models and describing routes with logical switches.

This paper takes the multiposition control of single group light for a example,analyzes the inadequacy of the existent multi-position control circuit of mechanical selector switch,and introduces the basic working principle and practical circuit of the multi-position control circuit formed by the electronics logic switch.
