The expert system is widely required to produce absolutely exact switching sequences and working-arrangements which are conformed with the request of production . However, firstly most working-arrangement ES is separated with the switching-sequence ES , which may cause that the two sheets can not parallel . Secondly ,when an expert system is developed, software reuse is not enough and the productivity of software is low. For these instances, an idea to build switching- sequences & working-arrangements ES based on component object model(COM) is brought forword through the study of the universality and maintenance of the expert system and the reuse model of software engineering , Applying the idea of this paper , the question of reuse in development is solved , and the universality and maintenance can be greatly improved.
