Design And Implementation Of Simulation Configuration System Based On Workflow

With the continuous deepening of economic globalization and the continuous development of informatization construction,enterprises need to adapt to the complex and changeable needs of the new era to carry out new business and scientific research personnel to conduct new research.Certain scientific research experiments are difficult to carry out directly in the real world due to their hazards,long periods,and harsh environmental requirements.The use of simulation technology can effectively carry out scientific research that is difficult to carry out experiments in the real world.High Level Architecture(HLA),as a general simulation technology framework,is suitable for the development of simulation systems in general fields.Simulation models can deepen the understanding of simulation scenarios and facilitate communication among simulation developers.Model Driven Architecture(MDA)technology can extend the concept of models to all stages of software design and development.It is the mainstream model integration solution in the industry.Based on the workflow method,this paper explores the method of constructing platform-independent models that can summarize general simulation scene knowledge,and designs and completes the simulation configuration system.The main tasks completed in this paper are as follows:First,analyze the problems in the visual modeling of simulation applications based on the HLA architecture,and establish the mapping rules from the basic primitives of the Business Process Model and Notation(BPMN)to the simulation concepts in the HLA,and use this set of rules to perform Visual modeling of the simulation process.After that,an algorithm for transforming the constructed target simulation scenario process model into a finite state machine(Finite State Machine,FSM)model of multiple simulation roles is proposed,and the resulting finite state machine model is used to simulate behavior logic based on a model-driven approach.edit.Using this set of solutions can solve the problem that the model of multi-role coordination is not easy to drive,simplify the difficulty of configuring the simulation role behavior information,and comply with the structural characteristics of the HLA code.Secondly,complete the definition of the meta-models for federation,federation members,events,announcement subscriptions and objects,and give the conversion and matching relationship from the process model meta-model and configuration information meta-model to the HLA simulation information meta-model.Complete the configuration of Federateion Object Model(FOM)and Simulation Object Model(SOM)information,the life cycle information of federated member instances,and the information of federated external events required for generating simulation applications based on the HLA architecture.According to the definition of the meta-model,the configured multi-dimensional simulation information is used to construct a Platform Independent Model(PIM)file that can fully describe the knowledge of the target simulation scenario.Finally,the requirement analysis is carried out for the simulation configuration system based on the workflow mode,and different functional modules are divided,and the main database table structure design is completed.Design and implement a simulation configuration system based on workflow,and introduce how the specific services of each part of the system are implemented.Through the fishing gear production simulation scenario case,the test of each part of the system is completed.The fishing gear production simulation platform-independent model obtained by the system configuration is verified by the downstream HLA-based general simulation support system,and the simulation code that runs well can be obtained.Verify the validity of the PIM file generated by the system.
