Research On Architecture Of System-of-Systems Evolution Scheme Generation Based On Bilateral Negotiation Method

With the rapid development of Internet technology,informatization has become the current trend of the times,system-of-systems that can be interconnected,communicated,and interoperable become the way to accomplish tasks.However,in the life cycle from appearance to demise,the development of artificial system-of-systems will encounter many uncertain factors,including changes in high-level missions,replacement of old and new systems,iterative updates of technologies,and changes in laws and regulations,etc.These factors will have different degrees of influence on system-of-systems,which will lead to the incompatibility of the operating system with the environment in which it is located,and urgent adjustment plan are sought,which is called " system-of-systems evolution".This paper takes the high-level abstract Acknowledged system-of-systems architecture evolution as the research object,analyzes the system evolution process,dynamic adjustment plans of resources and architecture evolution methods,and specifically studies the following aspects:(1)We analyze System-of-Systems Evolution Characteristics.System-of-systems is consisted of systems,which is a special system.Analyzing the evolutionary characteristics of system-of-systems helps to grasp the changes before and after the evolutionary system-of-systems.Meanwhile,locate the entry point of the subject under study.The five aspects of system-of-systems characteristics,system-of-systems basic types,system-of-systems evolution forms and system-of-systems evolution classification are described in detail.(2)We propose the Evolution Process of Architecture based on Wave Model.The evolution process of the architecture is analyzed emphatically,and the basic steps of evolution are described in detail.Then,combined with the wave model,the evolution process of the architecture in the life cycle is described,and the evolution process of the architecture in a wave model is highlighted.Simultaneously,the negotiation thinking and method are introduced,and the evolution process of the systemof-systems architecture based on negotiation is expounded.(3)We propose a Bi-level Multi-Objective Programming Model for System-of-Systems and Systems Negotiation Quotation.To make system-of-systems and systems smoothly enter the negotiation mode to realize the requirements of architecture change.Before negotiation,both parties need to model and calculate the multi-attribute quotation.This paper proposes a multi-objective programming model suitable for dual decision makers.Combined with the improved multi-objective optimization algorithm,the system-of-systems and systems’ negotiation quotation scheme are obtained,and the system composition and multi-attribute negotiation quotation values to be added are clarified.(4)We design System-of-Systems and Systems Bilateral Multi-Attribute Negotiation Models.The key to solving the problem of architectural change during evolution lies in the negotiation results of the system-of-systems and systems.According to the final negotiation plan,the composition system,interface relationship and overall architecture of the system-of-systems in this wave will be determined.This paper designs a two-stage one-to-many attribute negotiation model.In the first stage,the negotiating participants hold a fixed willingness and conduct bargain-style iterative negotiations with their opponents until the end of the negotiation or the maximum number of negotiation rounds.In the second stage,the negotiation participants will master the historical quotation information,and adjust the willingness parameters through learning,and the negotiation will proceed to the transaction between the two parties or the maximum number of negotiation rounds.Finally,a set of systems’ composition and interfaces’ composition schemes that can adapt to the current system-of-systems evolution requirements are obtained.
