摘要: 制订基于协商的虚拟企业项目规划不仅要考虑任务时间与工期的可行性,而且要关注费用与资源的优化。通过分析虚拟企业项目协商规划的工期与费用的不确定性,首先提出了多属性随机项目模型;接着提出了工期—费用并行协商规划算法,以期望工期费用为优化目标,结合示例解释其计算过程;最后针对模具生产的特点,对模具虚拟企业的项目进行仿真规划,说明了这一方法的有效性和可靠性。

Abstract: When the virtual enterprise makes the schedule of the project in a negotiation way, it should not only consider the feasibility broken by the time conflict among the activity implementations, but also pay attention to the optimization of the resources. A multi-issue stochastic model, which can describe the uncertainties of the durations and the costs of the activities in the project, is first put forward. Based upon this model, an algorithm, which can make a schedule and allocate the resources simultaneously in a negotiation way, is then presented at the goal involved with the expectations of the activity dura-tions and costs. The implementation of such an algorithm is explained with a simple example. As for the characteristics of the mould and die manufacturing, the algorithm is carried out on a manufacturing project of the industry. The simulation re-sult shows that the model is applicable, and the algorithm is reliable and effective as well.
