针对并行活动中并行时间和返工作业相互牵制的问题,分析了成对工作并行、多紧前工作并行、多工作同时并行模式下的返工机制,揭示了返工量与各影响因素之间的关系,给出了返工量的计算公式,构建了并行工作模式下全过程设计的工期算法。以最小化设计周期为优化目标,设计了矩阵编码的遗传算法,求解各工作间并行度。最后,以一般商业办公楼的设计过程为例,验证了算法的可操作性和实用性。
Aiming at the problem that parallel time and reworking work in parallel activities are mutually restrained, the paper analyzes the rework mechanism of paired work in parallel, multi-work in parallel, multi-work in parallel mode, reveals the relationship between rework and each influencing factor, The calculation formula of rework quantity is given, and the construction period algorithm of whole process design under parallel working mode is constructed. In order to minimize the design cycle as the optimization goal, a genetic algorithm of matrix coding was designed to solve the parallelism between workplaces. Finally, taking the design of general commercial office as an example, the feasibility and practicability of the algorithm are verified.
