Based On EOOPN Modeling For Mission Reliability Of Equipment System Of Systems

Modern warfare is a counterwork between the weapon system of systems,Reliability especially mission reliability evaluation is an important aspect of theequipment system design. Since the equipment system of systems is complex, and themission is varied, currently simulation-based method is more feasible to solve themission reliability evaluation problem. Petri nets can better describe the sharing ofresources and complex logic, suitable for the characteristics of equipment system ofsystems.On the basis of summary and analysis of relevant research at home and abroad,In order to adapt to the mission reliability modeling characteristics for the equipmentsystem of systems, the traditional Object Petri Nets is improved, then the missionreliability modeling based EOOPN have been proposed and The problem of theauto-generation of mission reliability model have been researched.The main research content and innovation as follows:(1) For the problem of mission information description, based DoDAF2.0, the datamodel of mission reliability information and the reliability Perspective view product sethave been presented, then gives the product template based on UML to implement thegoal of mission information visualization and standardized description.(2) For the problem of the poor ability of the traditional reliability modelingtechniques for dynamic description of the weapon system of systems, Object Petri netmodeling method has been researched. and for the requirement of weapon system ofsystems modeling, this paper improved the Object Petri net from the network structureand modeling elements, and proposed a new object Petri net-EOOPN.the introduction ofthe information broadcast place and information receiving place give a distinctionbetween information flow and material flow to adapt to the modeling requirement s ofweapon system of systems based information systems, and based XML this paper givesthe EOOPN model specification.(3) This paper gives the mission reliability modeling method based on EOOPN, theprinciples and steps of conversion from mission information description model tomission reliability model is proposed. More, the reliability modeling and simulationplatform software EOOPN design work has been carried out, laid a good foundation forcomputer aided modeling.(4) Take the mission reliability modeling and simulation of the air and missiledefense system of systems as a sample application, the effectiveness of the proposedmodeling techniques and processes by this paper is verified.
