Currently technologies of Web services have greatly developed and provided a new application platform for CSCW. For a business process across enterprises, cooperation of multiple Web services is usually required to achieve the final goal. However, most current Web services choreography proposals, such as BPEL4WS or WSCI, only provide a fixed execution flow, lacking of flexibility and adaptability. In this paper, we propose a flexible workflow model TDWF, which can specify the execution process of Web services according to task dependency information, so that the Web services can be composed dynamically. We also put forward an algorithm to verify the correctness of the composition process. Besides, the proposed compensation mechanism of workflow could properly satisfy the requirements of end users

In order to resolve the composite material multi-objective topology optimization in aircraft design, a multi-objective aircraft optimization system based on grid technology, the multi-objective optimization grid (MOOG) is put forward. Using grid middleware, MOOG pooled the distributed computational resource into a high-performance computing platform and built a common genetic algorithm computational model towards multi-objective topology optimization. This system provided uniform resource service and visible user using interface. This thesis discussed in detail the system design and the improved multi-objective genetic algorithm. Finally, the solid experimental results of optimizing one type of high aspect ratio wing show that the MOOG has reduced the computation time and has good parallel acceleration
