Research On Model, Simulation And Optimization For Task Oriented Command And Control Organization Based On Colored Petri Net

Joint operation under information era requires more effective command and control organization.Nowadays,the system of Command and Control(C2) is the outcome of industry age.The main character of the C2 organization is short of agility,which makes the C2 organization can not meet the requirement of joint operation under information era.There have been many methods of designing C2 organization to solve the problem, and these methods have themselves characters and shortcomings.Therefore,it is an important and valuable problem that quickly evaluating the matching degree between C2 organization and its mission environment and then choosing the best one for application.Furthermore,most of the current methods design C2 organization based on static mission environment,which is very brittleness under dynamic mission environment.Then it is a new issue that studying the optimization of C2 organization under dynamic mission environment.For settling the above problems,the thesis presents the concept of Task Oriented Command and Control Organization(TOC20).The thesis studies the methods of modeling TOC2O based on Colored Petri Net(CPN) from 3 views,i.e.no mission environment,static mission environment and dynamic mission environment,and then analyzes the matching relationship between TOC2O and its mission environment by running the simulation model which can support the optimization of design methods and contrast among different TOC2Os.Finally,the thesis studies the processes and algorithms of robust and adaptive optimization of TOC2O and validates the algorithms by cases.The primary work and contributions of the thesis are as follows:(1) Presenting the concept of TOC2O and building the framework of modeling TOC2O.The thesis presents the concept of TOC2O,which is composed by mission task, command and control resource,and decision maker;analyzes the construction process of TOC2O and contrasts the similarities and differences between TOC2O and virtual organization;building the multi-level description model after analyzing the relationship among mission task,C2 resource and decision maker;setting up the simulation framework of TOC2O based on the method of combining the object oriented theory and the Petri net theory;establishing the UML model of TOC2O and analyzing the relationship of the 3 kinds of object by state chart.(2) Researching the capability of TOC2O structure under no mission environment based on information process view.The structure of TOC2O is the main research object under no mission environment. Based on the information process view of Computational and Mathematical Organization Theory(CMOT),the thesis studies the speed and quality of information transferring,which are used for analyzing the design parameter and capability of C2 organization.The thesis defines the concept of delay of C2 organization,and then studies the model of delay by Shannon entropy of network.Besides,the thesis studies the issue of information distortion in C2 organization,builds the simulation model of the C2 organization structure,and contrasts 8 kinds of typical C2 organization structures.(3) Studying the method of setting up the CPN model of TOC2O with steady model structure,and investigating the matching relationship between TOC2O and its mission environment by simulation.The thesis studies the method of building the CPN model of TOC2O based on the simulation framework of UML.During the period of modeling,the thesis introduces the concept of model variable in CPN,which can describe all kinds of parameters of TOC2O by initial tokens;at the same time,the thesis introduces the concept of control variable which can describe many complex operation of TOC2O.These two kinds of elements can guarantee that the CPN model of TOC2O have steady structure under dynamic mission environment or even for different TOC2O structures,which can improve the speed and efficiency of modeling.After set up the CPN model of TOC2O, the thesis defines the performance parameters which descript the matching degree between TOC2O and its mission environment.By running the CPN model,the thesis contrasts 4 kinds of TOC2O design methods under static and dynamic mission environment.The result shows that the CPN model of TOC2O can measure the matching relationship between TOC2O and its mission environment.(4) Establishing the model of robust and adaptive optimization of TOC2O under dynamic mission environment and putting forward the corresponding algorithms.The parameter of mission environment is uncertainty under dynamic mission environment.The simulation result of TOC2O's CPN model shows that it is necessary to optimize the TOC2O under dynamic mission environment.In the mathematics model of robust optimization of TOC2O,each mission of dynamic mission environment is looked as a probability affair,and the optimization goal is meeting the requirement of mission with high probability.The thesis studies the group genetic algorithm for solving the model.On the other hand,the thesis studies the adaptive optimization of TOC2O.At first the thesis analyzes the cost of performance and the cost of reconfiguration under dynamic mission environment.Then the thesis researches the model of adaptive optimization whose goal is minimizing the power sum of performance cost and reconfiguration cost.And the Dynamic-Window-Search Ant Colony Optimization Algorithm(DWSACO) is put forward to resolve the model of adaptive optimization. Finally,the thesis validates the correctness and effectiveness of the two algorithms by cases.
