Research On Theories And Methods Of Modeling, Measuring And Systemizing Materiel Requirements

In information-based warfare, weapon materiel is not isolated but interdependentand interactional.The requirements are complicated. Operation, system and technologyareallinvolvedinmaterielrequirements.The relations amongoperationalrequirements,system requirements, and technological requirements are complex and evolutive. Theimportant factors indeveloping materielrequirements are roles, resources and motives.Roles are the individuals or the organizations that undertake obligations. Resources arethe weapons or the technologies that exist or will exsit in given period. Motives aremilitary missions or operational tasks. The factors bring nonlinear characteristics tomaterielrequirementsdevelopment.Apparently,systematizationisindispensable.Systematization of materiel requirements development involves three importantaspects. Involved are:â‘ what are the characteristics of materiel requirements and whatare the characteristics of materiel requirements reflection,â‘¡how does materielrequirements reflection reflect materiel requirements scientifically, andâ‘¢whichtechniques are necessary for developing materiel requirements. The basal theory, themethodological framework, the key engineering techniques and the applicationdemonstrationarediscussedtoexpoundhowtosolvetheproblems.Themaincontentsandfruitsofthispaperareoutlined asfollows:Firstly, basal theory, which is the theoretical basis of materiel requirementsdevelopment,isstudied. By usingformulas ofrelation algebra and higher-order logical,problem frame for materiel requirements is brought forward and a reference model isdefined. Problem frame focuses on the relations between weapon materiel and theproblems to besolved. The reference modelfocuseson talkingabout keyartifacts, theirattributes, and relationships at a general level. In particular, the relations that materielrequirements and materiel requirements reflection must satisfyare analyzed. Adequacyandnecessityareincluded.Necessityofmateriel requirementsmeritssomeappreciationforthereareavarietyofwaystogetwrongproperty.Necessityofmaterielrequirementsreflectiongives responsibilities to the roles. Obviously, the framework can serve as theguidelinefordeveloping materielrequirements.Secondly,theframework ofmateriel requirementsdevelopmentisstudied. Inorderto illuminate restricts and fundamentals for developing materiel requirements,conceptual model for developing materiel requirements is brought forward. Commonconcepts and terminologies, which are often used to developing materiel requirements,are defined. At the same time, relations are explained and clarified. Based on thecharacteristics ofmateriel requirementsandthe evolutionaryrulesof weaponmateriel,athree-dimensional (3-D) taxonomyofweapon materiel isput forward.Weapon materielis classified according to three levels of task illegibility, three levels of structurecomplexity, and three levels of technological uncertainty. By using fuzzy theory, givenweapon materiel can be positioned in reference frame of 3-D taxonomy. Based on the premisethatmateriel requirementsdevelopmentmustbeadaptiveto thetype ofweaponmateriel, it is suggested thatmateriel requirements development comprise threemodes.Included are reproduction, discovery and creation, which make requirements be exact,rightand advancedrespectively.Thirdly, the first step in developing materiel requirements, i.e., building materielrequirements models, which transforms the subjective cognition into the objectivedescriptionof materiel requirements, is studied. Based on the idea of modelingmaterielrequirements, elements and forms ofmateriel requirements model are studied. In orderto model materiel requirements normatively, ontology of materiel requirements ispresented, which includes ontology model and semantic ontology model. In particular,the paper focuses on clarifying the domain knowledge about materiel requirements.After that, aprocedure for modelingmateriel requirements is given.At last, an exampleshowsthattheapproachishighlyfeasible,effectiveandpromising.Fourthly, the second step in developing materiel requirements, i.e., mappingmateriel requirements measures,which transforms the objective description of materielrequirements into the measurable criteria, is studied. Based on the idea of measuringmateriel requirements, the structure of the measures is studied. Materiel requirementsare expressed as task needs,capability needs and capability gaps. In order to measuremateriel requirements, an approach toorienting capabilities towards tasks is presented.The process is divided into four phases to get them. Included are operational taskanalysis, function and activy analysis, operational capability analysis and capabilitygaps analysis. At last,an example about an air interdiction operation is presented forspecifyingtherelationsamongthephasesandtheobjectsofeveryphase.Fifthly,thethird step indevelopingmateriel requirements,i.e.,integrating materielrequirements reflection,which systemizematerielrequirements,isstudied. Basedontheobjective of systemizing materiel requirements, hiberarchies and relationships ofmateriel requirements reflection are studied particularly. Involved are macroscopicalhiberarchies, microcosmic hiberarchies, macroscopical relationships and microcosmicrelationships. SMA (Synthetic Microanalytic Approach) is studied.After that, anapproach forintegrating materiel requirementsreflectionbasedon SMAispresented.Lastly,anapplicationdemonstration,whichtakes the requirements development ofC4ISR systems that support the battle of joint firepower strike in information-basedwarfare as background, is studied for validating the feasibility and validity of themethodologiesinthispaper.Theexampleshowsthatthe Approachisfeasible.
