Research On The Method And Application Of The Architecture Modeling Of Weapon System-of-Systems Based On Capability Requirement

Weapon system-of-systems (WSoS) is made up of all kinds of weapon systems that have interrelation and interaction in system function to meet the requirement of combat operation, and it has higher hierarchy and more complicated architecture than weapon system. The architecture modeling of WSoS focuses on process, method, description and synthetically analyze of modeling, it can provide support of theoretics, methods and technique to every phase of architecture design and system-of-systems (SoS) construction. At present, most researches of architecture modeling methods and frameworks in the world take the Department of Defense Architecture Framework (DoDAF) as the template to make a secondary development. These researches don't have the response of SoS capability requirement, they are lack of the quantitative analysis of the interrelation, and they can't provide feedback and guidance to the architecture construction. Furthermore, the architecture modeling data of these researches has a low reuse rate and doesn't have the coherence. Considering the shortcoming above, the most important problem to reserve of the architecture research to the actual situation of our country is to find out a WSoS architecture modeling method.This dissertation presents a method of the architecture modeling of WSoS based on capability requirement. The main contents and achievement of this dissertation are listed as follows:(1) An architecture modeling framework based on capability requirement is presented to standardize and guide the whole process of the architecture modeling operation. A new pattern of architecture modeling based on capability requirement is presented. The architecture modeling framework is made up of four parts, they are:"modeling from requirement to architecture", which describes how to build an architecture of WSoS from the capability requirement;"modeling of architecture", which describes the foregoing WSoS architecture in all-around;"modeling from architecture to capability", which describes how the capability of the WSoS architecture satisfies the capability requirement;"analysis of modeling process", which analyzes the information of the modeling process such as approach, method and data, and guides the modeling process.(2) According to the different phases and content of the modeling process, different approaches of modeling are researched. For"modeling from requirement to architecture"and"modeling of architecture", considering the characteristic of each modeling object, using IDEF0 and IDEF1X for reference,"structured modeling analysis"is used to build the model of the process. For"modeling from architecture to capability", according to the process of modeling, analytic network process (ANP) with improved fuzzy exponential scale is used to build the mapping relationship of system functions and capabilities of SoS, and analyze how the system functions contributes to the capabilities of SoS. Satisfied degree of system function is defined to be including proximity and relativity, and GCA-TOPSIS is used to build the modeling. For GCA-TOPSIS, TOPSIS is used to analyze the proximity and grey correlation analysis (GCA) is used to analyze the relativity. By synthesizing the proximity and relativity, the analysis of satisfied degree of system function can be obtained. Combining the contribution analysis result with the satisfaction analysis result, the satisfaction analysis of WSoS architecture to capability of SoS can be obtained.(3) Design and develop a series of modeling description products to support the architecture modeling process of WSoS based on capability requirement, which include 12 kinds of description products and 20 kinds of sub-products, each describes the modeling process from different viewpoint with certain forms. The usage, contents and forms of modeling description products are designed in detail, the data format and coherence principle of the description products are standardized, and the logic relationship and data correlation of the description products are analyzed and built up.(4) In the guidance of architecture modeling framework and method, the modeling software is developed. The structure, function and use flow of the software are designed in detail. By using the modeling software, according to the modeling process, applying the modeling method, an example research with the architecture of precise strike WSoS in long distance is taken, and a series of modeling description products are developed, which can illustrate the feasibility and the practicability of the modeling method presented in this dissertation.
