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.
