Object Petri Net (OPN) which combines Petri net with object-oriented theory gives an effective method to use the Petri net in the field of M&S of Discrete Event Dynamic System. The concept and mechanism of object is brought in, and the function of basic Petri net is expanded. It is a new idea to apply OPN to missile operational effectiveness assessment system. The expanded function of OPN is helpful for M&S of discrete missile combat system. Since kinds of stochastic factors of the combat are considered in the simulation, the assessment of operational effectiveness has high reliability. The structure and the combat process of ICBM combat system are studied, and then the framework of OPN-based missile operational effectiveness assessment system and its operational mechanism are given.

The analysis and evaluation of weapon system is a kind of systems engineering, the core of which is to assess firing effectiveness and operational effectiveness. It is defined in Ref.1 that a system’s comprehensive capability to complete its mission is named system effectiveness normally; and the successful probability of a system to meet the operational requirement under special conditions during special time is named operational effectiveness of weapon system. The analysis of effectiveness is mainly concentrated on two aspects at present. One is to study the single kill probability based upon the analysis of accuracy of guidance or impact point of a single weapon. The other is to evaluate the capability of weapon system and local or overall defense system to fulfill the operational tasks. Petri net is an effective method to study DEDS, which is widely used in this field. Object Petri net (OPN) is a kind of high-class Petri nets, which is rising in recent years. The technique of OPN is applied to assessment of missile combat operational effectiveness in this paper, and framework of assessment is established.
