Conceptual Model of Complex Simulation System (CMCSS) is one of important research content in simulation domain. Complex simulation system (CSS) has characters of more entities, complex behavior and many kinds of interactions, etc, and need a lot of persons to take part in its development, that makes it is very difficult to understand simulation object consistently. It blocks efficient of development of complex simulation system that short of specification about simulation object. This paper put forward a set of system solution to CMCSS modeling and evalution.A technique framework of CMCSS is set up according to analysis on requirments of techniques and methods in CMCSS life circle, and CMCSS meta-model is put forward. This paper provides a incorporate modeling method and formal evaluation method, and develops a tool to assist CMCSS modeling and evalution.Firstly, the technique framework of CMCSS is studied. A modeling process and evaluation process model of CMCSS are built, and techniques and methods needed in processes are analysis, then the technique framework of CMCSS is given. CMCSS technique framework makes a guide effect to research on CMCSS, in which the purpose, meaning and problems resolved of each technique and method are described. Also a CMCSS meta-model is build. CMCSS technique framework provids foundation for CMCSS research.Secondly, the modeling technique of CMCSS is studied. Based on CMCSS meta-model, an incorporate modeling method of CMCSS is research. The method combines the modeling process of CMCSS closely, and provides the efficient modeling method according to all different requirements of different steps in modeling process. CMCSS incorporate modeling method applicants XML technique, graph technique and formal technique. The data modeling method based on XML can satisfy the requirements in data level. The visual modeling method based on graph can satisfy the requirements in visual level. The formal modeling method based on set can satisfy the requirements in analysis level. The meta-model of CMCSS is foundation of CMCSS incorporate modeling method, and it provides basis for transform between different level CMCSS. To make CMCSS has a clear structure, it need to decompose CMCSS to diffirent level, so this paper research architecture description of CMCSS to satisfy diffirent person's requirement.Thirdly, the evaluation technique of CMCSS is studied. A formal evaluation method is put forward after analysis on disadvantage of traditional evaluation method. Formal evaluation method based on point of view of system evaluation, can achieve full evaluation on CMCSS. Its application foundations are evaluation index using formal description, the formal method of getting evaluation index value, and arithmetic of evaluation result. According to this idea, the principle of formal evaluation method is analysis, and the evaluation index system is built after analysis on the effectiveness of CMCSS quality, and then each evaluation index is described in formal technique. The formal method of getting evaluation index value is studied according to formal index, and also the evaluation sequence of evaluation index is given. The arithmetic of CMCSS evaluation result is studied, and problems cast back are discussed, then CMCSS credibility is analysis. A model of reachbility of CMCSS is built, and the reachable probability is research, alse a model of time waste is built.Forthly, a tool to assist conceptual modeling and CMCSS evaluation is developed. It is necessary to use tool assist CMCSS modeling and evalution, for CMCSS contains a mount of information. An architecture of assistant tool is designed. The tool is designed to include three parts: conceptual modeling module, CMCSS evaluation module, and CMCSS management module, then the design and function of each module is introduced.Finally, in view of a resistance system of missile attack-defence, its CMCSS is established and is evaluated using the paper's research results, to confirm the paper's research results is feasibility.
