摘要
针对建筑工程施工工期的不确定性,引入模糊数学理论,采用6点模糊数表示工期。以建设单位对优化工期的满意度和可靠性作为优化目标,建立资源受限条件下施工进度数学优化模型,利用进化算法对施工进度进行优化。通过建筑工程实例,证明了本研究设计的算法的有效性和可行性。
In view of the uncertainty of building construction, fuzzy due date is denoted by six-pointfuzzy numbers through the introduction of fuzzy mathematics. Based on the objective to maximize the clients＇ satisfaction degree and the reliability of the optimization result, the mathematical model forfuzzy resource-constrained project scheduling is established. By use of the evolutionary algorithm, theoptimization of project progress under the limited resource is studied. The result of the computational experiment shows the algorithm is effective and feasible.
