Multidisciplinary Optimization Based On Bpel Process Modeling And Scheduling Technology Research

With the development of scientific and internet technology, Multidisciplinary Design Optimization is facing more and more problems. Large-scale distributed application makes the computation in all disciplines to be service, meanwhile, the needs of dynamic balance increase continually because of the complication of Design Optimization. As a result, it is needed urgently to find out a new modeling way of dynamic design optimization which fits in the distributed environment. Aim at questions above; this article will do following works.First, after studying modeling methods of multidisciplinary design optimization which has been already made by previous researches, this paper will provide a method that will be used in the distributed web service. In the stage of process modeling, this method will be able to organize each discipline in the way of distributed service, which will improve the reusability of the model and reduce the complexity of the model.Second, present academic field tends to be service-oriented and multidisciplinary design optimization is in a predicament. In such an environment and in order to achieve the optimization of design, this paper will study the characteristics of BPEL, and then combine BPEL and multidisciplinary design optimization process modeling together, and then construct design optimization rationally by using web service combination.Third, based on that the practical needs of which process management of optimization design of multidisciplinary is dynamics, this paper provides a dynamic expanding method which is based on the technology of reproducing the data access and operating the web service dynamically. This method realizes the typical demand of process management of optimization design of multidisciplinary with dynamic.Lastly, this paper has investigated the requirements of modeling and scheduling in multidisciplinary design optimization and studied BPEL and relevant field. After that, this paper realizes the tools of process modeling and the platform of scheduling management in multidisciplinary design optimization. By constructing the process model and Riftsaw a open source BPEL engine, this paper achieves the purpose that the process is scheduled and managed in multidisciplinary design optimization and realizes the solution of auxiliary multidisciplinary design optimization.
