摘要
针对传统进度管理工具在反映工程变更(EC)造成的返工问题方面的不足,结合工序的工作流和信息流,建立EC返工风险矩阵,反映工程变更时工序间的信息交互情况。建立基于EC返工风险矩阵的关键工序优化模型,根据工序时间和返工风险区别对待各工序,采用遗传算法,以总协调时间最小为目标函数,实现EC返工风险下的关键工序最优排序,最大程度地避免返工循环。以某船厂的船舶建造流程为背景,采用MATLAB软件进行仿真分析,验证所建模型对工序优化的有效性。
In view of the shortcomings of the traditional schedule management tools in reflecting the rework problems caused by engineering changes(EC),the rework risk matrix of engineering changes is established combining the work flow and information flow of the process,which reflects the information interaction between the processes at the time of engineering change.The optimal ordering model of critical processes based on EC rework risk matrix is established.The processes are treated differently according to the process time and rework risk.By the genetic algorithm,taking the minimum total coordination time as the objective function,the optimal ordering of critical processes under EC rework risk is realized,which to a maximum extent avoids the rework cycle.Finally,taken the ship construction process of a shipyard as an example,the effectiveness of the established model on the process optimization is verified by the simulation and analysis with MATLAB software.
