Study of concurrent formalization of object model based on LOTOS

It is an efficient way to implement automation of software by applying formal methods to object-oriented technology.LOTOS is a powerful tool to describe concurrent operations,whose composition,operation semantic and precepts are introduced.In this paper,formal rules of state transient,state chart and concurrent objects are developed,which are applied to formulization of software.Furthermore,a case about GTP management sub-system is presented to demonstrate the method.
