Capability-Based Weapon System Of Systems Tradespace Multi-dimensional Multi-granularity Exploration Method And Application

In times of information warfare,the characteristics of system of systems(SOS)combat has become increasingly prominent.Especially the development of high technology brought huge impact to operation theories,military equipment and way of operations etc.The future high-tech warfare is nonlinear and asymmetrical Combat among systems and systems showing the new characteristics of multidimensional space,real time,pluralistic objects and diversified styles etc.These new features of high-tech warfare,presents a great challenge to the development of weapon and equipment system of systems(WSOS),that is,corresponding WSOS must adapt to the requirement of SOS combat with wide adaptability and rapid response capability against the changeable combat environment,diverse styles of combat,multiple types of combat missions.The demonstration of WSOS is an iterative process of design and analysis of the WSOS architecture.At the beginning of solution demonstration of WSOS,architecture design space is usually very large with few constraints at this stage.Since the architecture design will influence the late function and form of system,the cost of project will generally depend on the job of this stage,so ignoring the potential architecture solution may mean loss or failure of acquisition.Capability is the ability to complete a set of tasks and achieve the expected effect under the given standards and conditions by a series of means or ways.The formation mechanism of capability is reflected not only in the specific configuration of WSOS,but also in the way of using the equipment.In the exploration of the capability based acquisition design space,there are three key points: Firstly a great deal of possible architecture solutions must be able to be described in the early stage of acquisition and system engineering.Secondly there must be a mechanism to filter and explore the solution space,eliminating the unrealistic solutions or that can't meet the requirements of the mission.Thirdly there must be a method to complete fast and relatively accurate evaluation of the solutions,because there are still a lot of solutions need to be evaluated within the filtered solutions.This paper based on analysis of the characteristics and essence of the problem of capability thought based architecture solution generation and evaluation,considers several sections of formation,mapping and evaluation of WSOS architecture solutions.From the point of view of all sections of the solution and the key technical problems,a method to model and explore capability based WSOS architecture solutions is proposed expecting to make scientific decision and balance promoting the overall coordinated development of all kinds of weapons and equipment of WSOS,so as to achieve flexibility,adaptability and robustness of the SOS architecture combination solution,and eventually to ensure that the final constructed WSOS can maximize the overall quality and exert effectiveness of the whole.The main work and innovation of this paper are as follows:(1)A method of OPM based conceptual modeling and deducing of WSOS architecture solutions is proposed.Conceptual design is the most important stage during the life cycle of WSOS.The essence of capability requirements based modeling and exploration of WSOS architecture solution is the development and validation of operational plan and system solution according to the capability requirements,after which have been proposed,to form conceptual solutions meeting the capability requirements,and conceptual models of the capability solution space,so as to support evaluation of conceptual solutions through the deduction and simulation of concept models.But at present,when conducting the WSOS demonstration,all demonstration parties generally own an understanding of WSOS solution in the document,with rare formalized description of SOS solutions that are compliant to system engineering process from the stage of requirements to solutions,which leads to relatively ineffective conceptual design evaluation method of SOS.This paper proposes the thought of conceptual design and evaluation of architecture solution using OPM methodology,and two important advantages of OPM language are made full use of: One is that the structure and behavior of a system is integrated into a kind of view,another one is the hierarchically organized model diagram.The simulation experimentation and deducing is helpful to understand and explore the behavior of the architecture,reveal the concepts and logic problems,such as incorrect control flow,logic errors and loss problem of structure relationships among objects,which provides strong support for exploration of the WSOS architecture solution at the conceptual level in the early stage of demonstration.(2)A capability based evaluation strategy design space and its exploratory analysis method of WSOS are proposed.Based on the capability thought,starting from the definition and formation mechanism of capability,some methods and processes using key capability events as the main line to construct design space of WSOS capability evaluation strategy are put forward on the basis of WSOS capability evaluation.With the help of Agent based simulation theory,exploratory analysis for the evaluation strategy space is made through the multi-resolution factorial design and classification regression methods and so on.This method provides a good try for screening of SOS capability indicator at the beginning of the weapon and equipment acquisition.(3)A DM2 and ABMS based evaluation method of the capability of WSOS is proposed.Modeling and simulation is especially important in the each stage of development and evaluation of WSOS architecture solution.However,so far the research on the SOS architecture mainly focuses on the scope of executable architecture.There are rarely case and research on extracting related data from architecture products and applying those data to constructive simulation,and study reflecting data-centric thought is less and less.This paper concentrating on the early stage of equipment acquisition,using Do DAF2.0 standards for reference,explores and optimizes the solution space of WSOS architecture through the data-centric thought and Agent based modeling method.Based on the analysis of the SOS architecture solution description method,executable SOS architecture and SOS architecture driven simulation,the division of requirement space and solution space according to the system engineering thought is proposed in this paper.In addition,the SOS architecture data group is regrouped and capability based combination of architecture data meta-models(CBDM2)is proposed.On the basis of CBDM2 combined with the simulation requirements of ABMS,the exploration of data mapping method from CBDM2 to ABMS is made.This research can better promote the realization of coordination and cooperation between the architect and analysts,which integrates the architecture design and analysis together.(4)A RSBFNN based construction method of meta-model of WSOS architecture solution is proposed.In order to complete the capability based exploration and evaluation of WSOS architecture solution,mapping model from combat solution to combat effect of WSOS needs to be established.This paper combined NOLH(nearly orthogonal Latin hypercube)experiment design with multi-Agent simulation technology,puts forward the Rough Set based fuzzy neural network(RSBFNN)method used to evaluate the generated corresponding effectiveness of different configuration of SOS architecture solution.The experiment results show that,this method value is very reliable in the respect of forecasting the actual response and exhibits better performance than other models.This method is suitable for architecture designers to do a series of dynamic balance and analyses when exploring the WSOS architecture design,so as to complete fast comparison and research on the various possible architecture solutions.(5)A RST-SOM based bilayer design space exploration method of WSOS capability architecture solution is proposed.To address the problem of WSOS design space exploration based on the existing cases and operation data,a method of bilayer mapping and exploration of the solution space is put forward in this paper.By data mining technology combined rough set with self-organizing mappings,mapping from the performance space to the configuration space and that from the configuration space to the design space of SOS architecture solution space are completed,which leads to the realization of mapping from the performance space to the corresponding design space and completes a preliminary exploration and reduction of the overall design space.The bilayer mapping method proposed in this paper can explore the design space effectively to achieve the goal of reducing the range of the design space.To start from the basis of optimizing design of WSOS and to solve the problems of large amount of calculation and difficulty of optimization in the primary stage of conceptual design have a high practical significance.(6)An Agent modeling based solution space exploration method of WSOS and doctrine SOS is proposed.Capability based WSOS acquisition process should consider at the same time the equipment acquisition and possible use-pattern of equipment(doctrine based solution).But in the early stage of equipment acquisition,how to take both equipment factors and non-equipment doctrine factors into consideration so as to effectively make decision within the SOS solutions based on the goal of maximizing the operational capability is a very difficult thing with relatively few related research in this area.Based on the thought of Agent based modeling,this chapter analyzes the influence of equipment technology based solution and doctrine based solution on the capability,and quantitatively inquiries internal mechanism of SOS capability generation under conditions of different combinations of "method" and "means" within the capability generation elements,which provides methods and trains of thought for the capability based equipment acquisition and decision-making under the condition of information warfare.
