【摘要】：为了解决多项目环境下虚拟企业的创建问题,提出了采用最小粒度任务分解原则的任务分解策略和多项目动态环境的双向选择方法。认为任务分解方法和结果影响虚拟企业创建,通过对项目范围内优势企业资源的分类,建立与优势企业资源类别一一对应的最小粒度任务集。提出用任务影响因子矩阵方法实现项目目标到任务目标的映射,从而保证在项目分解时就能有效控制项目走向目标优化,使系统具有主动性。双向选择方法考虑了多项目动态环境对合作伙伴方案的影响,合作伙伴以盟主提供参数为中心,同时提供多时段、多参数方案,然后根据项目目标函数同时得出最优网络资源组合的虚拟企业创建方案和优化的项目计划。最后,以一个实例验证了开发的原型系统的有效性
[Abstract]:In order to solve the problem of creating virtual enterprise in multi-project environment, a task decomposition strategy based on the principle of minimum granularity task decomposition and a bidirectional selection method for multi-project dynamic environment are proposed. It is considered that the task decomposition method and the results affect the creation of virtual enterprises. By classifying the resources of superior enterprises within the scope of projects, the minimum granularity task set corresponding to the resource categories of superior enterprises is established. A task impact factor matrix method is proposed to map the project objective to the task objective, so as to ensure that the project can be effectively controlled towards the goal optimization when the project is decomposed, and the system has the initiative. The bidirectional selection method takes into account the impact of multi-project dynamic environment on the partner scheme. The partner provides multi-time and multi-parameter schemes with the partner providing parameters as the center. Then, according to the project objective function, the virtual enterprise creation scheme and the optimized project plan of the optimal network resource combination are obtained simultaneously. Finally, an example is given to verify the effectiveness of the developed prototype system.
