复杂建设项目的高效实施需要全面的施工计划。有必要考虑各种依赖关系和限制以及所需资源的可用性。高效调度的生成是一项非常具有挑战性的任务，它导致了NP难优化问题。本文提出了一种将离散事件模拟与优化框架相结合来确定高效施工进度的方法。这使得各种元启发式方法可以应用于调度问题。因此，可以在相对较短的时间内确定复杂施工调度问题的有效调度。通过实例验证了进化算法的优化思想。
The efficient execution of complex construction projects requires comprehensive construction scheduling. It is necessary to consider various dependencies and restrictions as well as the availability of required resources. The generation of efficient schedules is a very challenging task, which results in a NP- hard optimization problem. In this paper an approach is presented to determine efficient construction schedules by linking discrete-event simulation with an optimization framework. This enables the application of various metaheuristics to the scheduling problem. Thus, efficient schedules for complex construction scheduling problems can be determined in a relatively short amount of time. An example of implementation is presented to validate the optimization concept using Evolutionary Algorithms.
