摘要
无节奏流水施工是施工组织的常见形式。文章考虑了多项目环境下多模式的无节奏流水施工组织,并结合传统的time-cost置换问题进行了建模求解。目标函数直接采用双目标形式,并基于NSGA-Ⅱ非劣排序思想进行了算法设计。仿真测试表明,改进的算法能够有效的获得较优的离散time-cost曲线,可以为复杂环境下的无节奏流水施工组织与实施提供决策支持。
Non-rhythm flow process is a general pattern for construction organization. Considering the non-rhythm flow process under the conditions of multi-project and multi-mode, this paper modeled the problem combing with conventional discrete time-cost trade-off. The objective function adopted bi-objective expression. The algorithm was designed based on NSGA- Ⅱ methodology. The simulation results show that the improved algorithm can get the optimal discrete time-cost curve, which can provide decision making support for the construction organization and implementation in non-rhythm flow process under the complex environment
