带有资源依赖学习效应的多模态项目调度交互式群智能方法

Resource-dependent learning effects are not only an unsolved problem widely existing in the MRCPSP (multi-mode resource-constraint project scheduling problem), but also the primary factor affecting the correctness of processing time. Processing time and resource availability are key to the effectiveness of MRCPSP. The proposal mainly focuses on the critical problems in MRCPSP, which are learning effect modelling, dynamic resource allocation, and multi-mode multi-objective optimizaiton. The experience value of a resource, the fundamental parameter of learning effects, is obtained by evaluating the historically used information. The linked-list available time-fragment is introduced to dynamically distribute and recover resources. The real-time allocation and estimation strategy is developed. Appropriate available fragments are selected and combined into a whole one for the requirement. The resource-dependent learning effect model is built according to the experience value and the learning ability of a resource.An induced learning effect model is introduced for resources have variable learning ability. The internal related learning effects among different resources are presented according to their modes in an activity. As well, the external related learning effect is analyzed for resources shared by serial activities and concurrent activities. Based on the learning effect models, the comprehensive mathematical model is constructed for each resource to accurately estimate the processing time. The resource-constrained multi-mode project scheduling model with the resource- dependent learning effect is investigated to minimize cost and makespan with time-coast trade-off, for which an interactive swarm intelligence optimization algorithm is proposed. Accurate processing time and available resources could be obtained. Cost of the whole project could be reduced and reaource utilization could be improved, greatly.
