Research On Evolution Modeling And Exploratory Analysis Methodology For Weapon Equipment System Of Systems Development

Affected by entity structure, budget, production maintenance capacity constraints and other related factors, construction process of weapon equipment System of Systems (SoS) has shown the characteristics of the incremental development. In which there are a variety of evolutionary phenomena, such as formations, evolutions and devolutions. The study on weapon equipment SoS evolution will help us to understand the weapon equipment SoS's past and present, analyze and summarize the law of construction, forecast and plan for the future.The dissertation takes weapon equipment demonstration, especially planning and programming demonstration as an application background, and focuses on the research of modeling and experimentation framework for weapon equipment SoS evolution exploratory analysis and design under changes in demand. Through the exploratory analysis and design of weapon equipment SoS programming, an orderly, smooth and continuous construction process is expected. The contents of the paper are summarized into following parts:(1) According to practical needs of weapon equipment planning and programming demonstration, the main problems of weapon equipment SoS evolution exploratory analysis and design are discussed. Then, simulation technology is suggested to be integrated with constraint programming, and a Simulation-Based Constraint Programming (SBCP) integrated design framework is developed. Accordingly, methodology of weapon equipment SoS evolution exploratory analysis based on SBCP integrated design framework is proposed.(2) After the demand analysis of modeling for weapon equipment SoS entity structure, SH/CE/EB is set up as the modeling formal specification for SoS entity structure. Based on SH/CE/EB, trajectory generation mechanism of weapon equipment SoS evolution is designed.(3) Through integrating the trajectory generation mechanism with metaheuristics search technique, a technical framework for the searching in weapon equipment SoS evolution solution space is proposed. Under the technical framework, a hybrid Particle Swarm Optimization (PSO) algorithm and the load-balance mechanism for cooperative PSO is designed, which improved the search in precision and efficiency.(4) The relationship between effectiveness and capability for weapon equipment SoS evolution analysis is discussed. Weapon equipment capacity-demand analysis process based on Value-Focused Thinking (VFT) is designed. After this, the weapon equipment capacity-demand evolution modeling formal specification is set up. Then, the trajectory evaluation method based on weapon equipment capacity-demand evolution model is proposed. (5) Based on SBCP integrated design framework, simulation environment, SimEvolution, is designed and implemented to support modeling and experimentation in weapon equipment SoS evolution analysis. Moreover, the effectiveness of the proposed methodology of this dissertation is demonstrated by the application case of SimEvolution.The main innovations of this dissertation include: the SBCP integrated design framework, in which simulation technology is suggested to be integrated with constraint programming; the methodology of weapon equipment SoS evolution modeling and exploratory analysis based on SBCP integrated design framework; the modeling formal specification SH/CE/EB for SoS entity structure, the weapon equipment capacity -demand evolution modeling formal specification CapEvoModel, and the trajectory generation and evaluation method based on the formal specifications; a technical framework for the searching in weapon equipment SoS evolution solution space, in which Variable Dimension Greedy Randomized Adaptive Search Procedure (VDGRASP) and Variable Intension Mutation Procedure (VIMP) are designed to set up a hybrid PSO algorithm and the load-balance mechanism for cooperative PSO for improving the search in precision and efficiency.A smooth and orderly development is the new demands of weapon equipment demonstration in the new era and stage. As a supplementary for traditional means, the methodology of weapon equipment SoS evolution analysis and design provides a new way for planning and programming demonstration in breadth analysis and experimental research.Although the SBCP integrated design framework is mainly designed for weapon equipment SoS evolution problem, but it is still useful for other SoS evolution problems with multi-hierarchy entity structure.
