（1）最大完工时间最小：是指调度方案中完成各工件的加工所需时间最长的工

(1) The minimum maximum completion time: refers to the minimum completion time of the workpiece with the longest time required to complete the processing of each workpiece in the scheduling plan, which is an important indicator to measure the scheduling plan. Generally, the shorter the maximum completion time, the higher the production efficiency and the lower the manufacturing cost. It can be expressed as: (2) <br>Among them, is the completion time of the workpiece.

(1) Min max completion time: refers to the minimum completion time of the workpiece that takes the longest time to complete the processing of each workpiece in the scheduling scheme. It is an important indicator to measure the scheduling scheme. Generally, the smaller the maximum completion time, the higher the production efficiency and the lower the manufacturing cost. Can be expressed as: (2)<br>Where, is the completion time of the workpiece.<br>

(1) Minimum maximum completion time: it means that the completion time of the workpiece with the longest processing time in the scheduling scheme reaches the minimum, which is an important index to measure the scheduling scheme. Generally, the shorter the maximum completion time, the higher the production efficiency and the lower the manufacturing cost. It can be expressed as: (2) Where is the completion time of the workpiece.
