在重复性建设项目过程中，学习效应是一种很常见的现象。但目前还没有研究将学习效应应用到重复性项目的工期与成本优化问题中。本文将学习效应考虑到重复性项目最低成本问题中，分析了学习效应对项目成本的影响，建立了考虑学习效应的项目总成本模型，并设计了一种改进的粒子群算法进行求解。算例表明，学习效应有助于缩短项目工期、节约成本。本文研究有利于项目计划人员充分利用学习效应制定更为合理的进度方案。

The phenomenon of the learning effect is very common in repetitive construction projects. However, it has not been considered in the time/cost trade-off analysis. In this paper, the cost optimization problem in repetitive construction projects with the learning effect was studied, while meeting a prescribed deadline. The influence of the learning effect on the total project cost was analyzed, and then the mathematical formulation of the current problem was proposed. In order to solve this problem, an improved PSO algorithm was designed. The effectiveness of the proposed algorithm was verified by an illustrative example and the result indicates that considering the learning effect in scheduling provides more potential to reduce project duration and cost. The research presented in this paper can help the planner to establish a more realistic and reasonable planning.
