Research On Decision-making Method Of Command And Control Of Network Centric Warfare

Network centric warfare is necessary trend of information battle development, andas one important part of it, command and control system provides real time andreliable fighting command dccision for weapon system, making the holistic fightingefficiency of weapon system have its full play.The thesis has studied some main theory methods referred to the command andcontrol system of network centrie warfare, on the basis of these, a suit of thedecision-making simulation system of command and control has been designed.According to the characters and functions of network centric warfare, andintegrating the structure of tactics internets, the dynamic recombine decision-makingproblem of communication network in network centric warfare is researched. Thereinto, network recombine strategy and link recombine strategy have been researchedconcretely, and via simulation and testing on those two decision-making methods,validity and feasibility of two dynamic recombine strategies have been proved, whichprovide effective decision-making approach for communication network of networkcentfic warfare.Object threat assessment and firepower allocation are two important assistantdecision-making problems of fighting of command and control system. Aiming to thecharacteristic of object threat assessment, an object threat assessment model based onsupport vector machine (SVM) is put forward, and in order to make model hassubjective and objective characteristic, fuzzy synthetic evaluation method is adopt toobtain training and testing data for this model. Through a numerical example of aerialdefense object threat assessment and comparing with other existed methods, theresults show the rationality and superiority of the method. Considering theprecondition of counterwork between multi-weapon and multi-object, firepowerallocation model have been solved by genetic algorithm (GA) and particle swarmoptimization (PSO) algorithm separately, then through examples simulation andtesting, the results prove the validity and superiority of these two assistantdecision-making methods. Aiming at problems of efficiency evaluation and prediction on tactics internetsand C~4SIR system, one fighting efficiency evaluation method based on RBF networkof tactics internets and one fighting efficiency prediction method using Elmannetwork based on D-S evidence theory on C~4SIR system have been put forwardseparately. Via simulation of two methods, the results proves that RBF network cangive a effective static efficiency evaluation for fighting tactics internets, moreover,Elman network based on D-S evidence theory can forecast fighting efficiency changeprocession dynamically, which reduces the complexity of prediction model, andavoids uncertain factors existed in system, so one new approach on dynamicprediction of fighting efficiency has been set up.In order to economize construction expenditure of C~4SIR system and improvesystem fighting efficiency, a decision-making analysis model on ratio of cost to effectivenessof C~4SIR system is researched in the thesis. One uncertain multi-attribute decisionmodel existing fuzzy section data and weigh unknown of attributes is set up, whichgives synthesis evaluation on ratio of cost to effectiveness of C~4SIR system. In thisdecision-making analysis model, the optimization theory and expert loop method areadopted to obtain attributes weighs, via electing weighs value to adjust model trend,makes this model have more extensive ability.According to function and characteristic of command and control system ofnetwork centric warfare, the decision-making simulation system of aerial defensecommand and control system have been designed and realized. The structure,designing procession and simulation methods are narrated separately, in addition, thesystem simulation frame and software designing principle are also described, whichall these provide theory and technology references of constructing decision-makingsimulation of aerial defense command and control system in network centric warfare byway of adapting to demand of information battle.Finally, the thesis gives the summary and expectation.
