Abstract:

Quality problem is one of the main reasons for reworking of project, and the skill level of personnel is the key factor affecting the quality of project activities. Based on the general multi-skilled resource-constrained project scheduling problem, this paper comprehensively considers the influence of skill level of personnel and the quality transmission between activities on the activity completion quality, and further describes the reworking subnet and the reconstructed project network, in combination with a case study of a large shipbuilding project. The results show that the model proposed in this paper can effectively balance the allocation of limited human resources among different activities, reduce the diffusion of reworking risk and shorten the total project duration. Moreover, through random experiments of disturbance parameters of quality interval as well as skill level, it verifies the robustness of the model proposed for the two parameters.

摘要：

研究表明，质量问题是项目返工的主要原因之一，而人员技能水平是影响项目活动完成质量的关键因素。基于一般性的多技能资源受限项目调度问题，综合考虑人员技能水平以及活动间质量传导作用对活动完成质量的影响，进一步数学表达级联作用下的返工子网以及重构的项目网络，并结合一个大型船舶制造项目案例进行实验分析。对比实验结果表明：所提出的模型可有效平衡有限人力资源在不同活动间的分配，有利于减少返工风险的级联，缩短项目总工期。进一步，通过质量评估区间和人员技能水平参数波动的随机实验，验证模型对两类参数波动具有一定的鲁棒性。
