operations scheduling

For the nonstandard Job-Shop scheduling problem ( NJSSP) in which some operations are processed on several identical machines, by the objective function of machine loads balancing nonstandard scheduling algorithm is presented.

针对加工工序的设备是多台具有相同加工能力的机器集合的非标准Job-Shop调度问题，利用机器负载平衡的思想构造目标函数，提出了非标准Job-Shop调度算法。

The conflict between the scheduling of the bottleneck machine and non-bottleneck machines can be coordinated by adjusting the release times and delivery times of operations on the bottleneck machine.

通过调整瓶颈机上工序的到达时间和传递时间协调瓶颈机与非瓶颈机之间的关联。

Under the assumption that the capacities of non-bottleneck machines are infinite, operations on the non-bottleneck machines are aggregated into a time delay. The job shop problem is then reduced into a single-machine scheduling problem with release time and delivery time constraints.

假设非瓶颈机加工能力无限大，将非瓶颈机上的工序集结成一个时间迟延环节，原问题则简化为一个带到达时间和传递时间约束的单机调度问题。

In the operations of the container ports, the berth scheduling problem is one of the main bottlenecks that restrict the container port to reduce the turnaround time of the ships and the operation costs.

在集装箱港口的运作中，泊位调度系统是制约集装箱港口降低船舶在港时间和运营成本的主要瓶颈之一。

And study on the current common container terminal production scheduling system, combined with the statues of the production operations in Xiamen port Haitian Container Terminal and the analysis of applications, work out the main function of production assist system.

并以当前常见集装箱港口生产调度系统的研究入手，结合系统应用所在地&厦门港海天集装箱码头的生产作业现状进行了现有系统及其应用的分析，提出了生产辅助系统的主要功能。
