A Method For Developing Multitask System——Generalized State Graph Method

In this paper,generalized state graph method is introduced. Generalized state graph method includes two parts,one is the generalized state graph design method,another is the state-oriented process design method.Based on traditional state graph,the concept of action node is introduced.Action node is used to represent the system action in a state transform,and the relationship among multitasks.State-oriented process design method, depending on the relationship between the elements of generalized state graph and process design,produces the process design of a multitask system from a generalized state graph directly.
