To solve the development problems of current WETS (Weapons and Equipments Training Simulation Software), a development approach of WETS was presented. The WSML (Weapons and Equipments Training Simulation Software Modeling Language) metamodel was constructed on metamodeling method, covering both function and non-function, by logical separation and description of every part of the system and relations between them. A domain-oriented modeling language is generated from the metamodel by the metamodel interpreter. A user model can be constructed according to WSML, source code can be generated automatically by the model interpreter and an application system can be compiled. Lots applications indicated that this method support model reuse and can improve development efficiency of WETS.

Mutual exclusion is an effective method of solving the conflict with the appliction of resource and sharing resources.But simple mutual exclusion bring some problems to the synchronization. Based on the Petri nets representation of the mutually exclusive process,analyse and propose an improved and optimized scheme,adopting the synchronic distance to analyse and calculate the logic and time synchronization distance and data synchronization strategy.It is proved that the improved scheme can reduce the synchronic distance of the process and decrease the runtime and resource consumption of the system.

To simplify the simulation system realization,conclude the rule of the mapping Petri nets to program code.Based on the research of basic elements and relation,construct 3 atomic sentences in view of logic relationship and combine to 2 kinds of molecular sentence.Take the example of prototype Petri nets,put forward the mapping method of circulation structure in the reachable marking graph.The mapping scenario of extended Petri nets with inhibitor arcs and controlled Petri nets are also put forward.All the research offer academic foundation for the mapping of Petri net to program code.

Composition and decomposition can be used in refining and combination of Petri nets. Based on the relation of in preconditions and consequences of Petri node, analysis the completeness of the composition and decomposition operation and put forward methods to improve the completeness, in this way can design correct and consistent Petri nets to describe the system.

This paper analyzed the problems in the development of equipment simulation software,discussed the makeup of the equipment simulation software in the view of developer.On this basis,the structure of development platform was designed and main functions of primary components were expatiated.At last,the characteristics of the development platform were summarized.

从面向对象的自顶向下的设计方法入手,利用Petri网的替换及合成运算,分析了对抗系统建模的顶层Petri网模型。通过进一步细化和分解,利用实际系统逻辑含义分析了各层Petri网的结构性质。为利用Petri网构造高层构建块和分解建模系统提供了一种思路。

This paper analyzed the function consistency, dominating consistency, state consistency and structural consistency of multi-resolution model based on three principles of the similarity theory. Then, a method of quality evaluation of consistency on state level and structural level are presented. The practice proved that this research is helpful to find the factors which influence the consistency and search for accurate measures to improve the consistency on every level.
