A Method for Estimating Project Duration in Program Evaluation and Review Technique 计划评审方法中项目工期估计的一种方法
Focused on the characteristics of the project organization mode and the uncertain information, by considering the effect of time on entire risk of virtual enterprise, the model of virtual enterprise risk evaluation is established based on program evaluation and review technique. 针对虚拟企业以项目为组织模式及信息具有不确定性的特点,为考虑项目时间因素对整体风险的影响,基于计划评审法建立了虚拟企业风险评价模型。
For the completion risk for the project of dynamic alliance, fuzzy program evaluation and review technique ( F-PERT) is adopted to describe the project, and the nonlinear integer model for the problem is established. Moreover, the F-PERT embedded genetic algorithm is proposed. 针对动态联盟企业项目完工风险问题,基于模糊计划评审法(F-PERT)描述项目的运行,建立了相应的非线性整数规划模型,并设计了嵌入F-PERT的遗传算法进行求解。
Based on this, there obtains the probability of completing the project within the time limit by exerting PERT ( Program Evaluation and Review Technique) to calculate the optimistic, favorite and pessimistic estimated time. 在此基础上,运用PERT技术(计划评审技术)对活动乐观、最可能、悲观时间的估计值进行整理计算,得出了该项目在要求工期内完成的概率。
It is a common to effectively control progress of the project in the Program Evaluation and Review Technique ( PERT) and critical path method ( CPM). 如何在项目计划上有效控制项目进度,最常见的是计划评审技术和关键路径法。
