研究了目标函数是最小化最大完工时间的同类机调度问题,其中作业具有尾时间。此问题等价于最小化最大延迟时间的同类机问题,并被证明是NP-hard问题。为此问题构造了一种启发式算法LPDT,进而以LPDT算法求解结果为初始解构造了问题的可变邻域搜索算法LPDT-VNS。大量的随机数据实验用于验证算法的性能和效率。
This paper considers the uniform parallel machine scheduling problem with delivery times so as to minimize makespan. This problem is equivalent to the uniform parallel machine scheduling problem to minimize the maximum lateness and is proved to be an NP-hard problem. We propose a new heuristic algorithm, named LPDT, and then build a variable neighborhood search algorithm, named LPDT-VNS, to improve the quality of the solutions that LPDT gave. The performance and efficiency of LPDT-VNS is tested on a large set of randomly generated instances. The results and analysis of experiments are reported and discussed.
