C To 4isr System Modeling And Analysis Technology Research

C4ISR System modeling and analysis, the key technique of efficiency evaluation in C4ISR system, is widely used in requirement modeling, analysis and design, demonstration and verification, item acceptance checking and efficiency evaluation.Based on comparing and analyzing the main recent previous study of C4ISR system efficiency analysis home and abroad, a novel idea on evaluation is proposed here, which combines the static model of the hierarchical efficiency evaluation on the foundation of the index system with the dynamic evaluation model. Especially, in the latter model, the matched degree of system space andmission is taken as standards. And we also establish an index system and a model of C4ISR system efficiency analysis correspondingly. After then some methods and algorithms are introduced, which include the principles and the method of choosing efficiency index and parameter index, the method of index filtering, the method of determining index function relation, the revising algorithm of AHP weight and the sort algorithm of judgment matrix.After researching deep into the building and combination on model based on database, the author puts forth a search algorithm of data mining by use of prototype library and a data-clustering algorithm on the basis of expanded CF-tree. Experiments indicate that these algorithms are able to create compound functions and cluster a mixed data set that contains continuous attributes and discrete attributes. On the basis of studying the models and the algorithms, a description language which can manage models and combine visual models and a tool which is applied to create combined model are designed and implemented. And the language and the tool can combine the elementary models visually to construct models for solving more complex problem.Taking UML and HLA as modeling and simulation standards, the architecture of the platform is presented, which is used to simulation verification and analysis of C4ISR system efficiency evaluation. Then the structure description model of C4ISR system, the edit tool and the integrative simulation platform are designed and implemented. Moreover, the approach of analyzing data based on simulation in this thesis separates the analysis of simulation data from the simulation entirely. Therewithal, whether a user builds the hierarchical model of evaluation or visualizes the data, he can define them himself after simulation finished. Furthermore, a user can define the relationship between index and simulation data. The calculation of hierarchical model can be non-linear, or the models that have been compiled can be invoked.On the background of a fictitious antiaircraft system, this thesis explains how to modeling visually, and how to simulate and analyze data according to scenario, scripture, simulation modeling and model combination. The study group being taken charge of by the author has developed "the Modeling Verification and Analysis Platform of C4ISR System " together. The appraisers report thatthis platform synthesizes modeling technique, component technique and several uptodate research achievement of HLA on the aspects of design idea and implement approach, which is an innovated technique. The technique of the platform keeps ahead in china. It provides the technique foundation and software environment for the total evaluation technology of C4ISR System evaluation, and is significant to promote the development and application of C4ISR System in our army.
