C4ISR system is the multiplicator of System of Armament systems (SoAS). An analysis method for Contribution Degree of C4ISR system is proposed in the paper. Firstly, Overall-Effect based evaluation method for operational effectiveness of SoAS is introduced. Secondly, Contribution Degree of C4ISR system is defined and experiment flow based on exploratory simulation is designed. On this basis, an analysis method for Contribution Degree of C4ISR system is put forward. Finally, a simulation experiment is executed to prove the effectiveness of the method.

In simulation grid, information sharing is very important for the grid units to cooperate with each other effectively and efficiently. In this paper, to resolve the problem of semantic heterogeneity, an ontology-based approach is proposed. In this approach, firstly, the local ontologies are merged into a global ontology based on their similarities. Then, with the merged global ontology, the semantic heterogeneity is resolved by comparing the classes and attributes of the local information source schemas. An example of how to resolve semantic heterogeneity in the E-government simulation grid is presented to illustrate this approach.

Through analyzing the theoretical basis and approach features of system-of-systems and cloud computing technology, the designing infrastructure and application flow of the meta-synthetic environment for equipment system-of-systems demonstration have been given with a combination of construction and application requirements of equipment system-of-systems centered on information. When designing the meta-synthetic environment for equipment system-of-systems demonstration, we adopted the way of Service Oriented Architecture (SOA), and put forward a model registration mechanism. By establishing the model registration principle, we designed and generated the model registration system, realized the model registration and management of the meta-synthetic environment to solve the quantification and evaluation issue and realized Design on Demand and Service on Demand of evaluation of the equipment system-of-systems demonstration meta-synthetic environment.

In order to resolve the problems resulting from various combinations of equipment selection, numerous uncertainties of future demands and the development process, a planning method based on the Markowitz model is proposed. First a qualitative analysis is performed and models of a combination planning method are produced, then a Markowitz model of the development plan of system-of-systems under uncertainty is built and solved by adopting a searching algorithm based on vector operation. Finally the effectiveness of the method is checked by scouting the development planning examples of the early warning surveillance system.

While the difficulty and complexity of simulation system increasing, the development efficiency and execution performance of the large-scale distributed simulation system (LSDSS) must be improved effectively. Furthermore, while the multi-core has become popular hardware, yet the traditional federate mechanism couldn't utilize and schedule the CPU resource, which would limit the simulation performance. Then PFHF, Parallel Framework for HLA Federate, was designed and realized to solve the problem above. PFHF could combine and construct federate from simulation model components, perform simulation engine management, data distribution management, object management, component management and load balancing function, etc., then support the integrated execution environment based on multi-core and parallel technique. Several experiments proved that PFHF could utilize multi-core CPU adequately, and reduce the LSDSS execution time efficiently.
