MRO服务企业如何科学合理地调配资源直接影响收益.从MRO服务提供商视角,综合考虑员工旅行费用和工作时间成本,研究为分布于不同地理位置的客户的设备提供维修服务的多技能员工的优化调度问题,建立了以维修成本最小化为目标的多技能员工优化调度的非线性整数规划模型.根据整数变量的特点将非线性模型进行线性化,形成线性整数规划模型,进而使用ILOG CPLEX优化软件进行编程求解.通过具有不同参数特征的大量仿真实验案例,验证了模型的合理性和有效性.

英文摘要：

The resources scheduled affect the profit of MRO （ maintenance,refair and overhaul）service companies directly. From the perspectives of MRO service provider, an optimizationscheduling problem of multi-skilled workforce working was studied for customers distributed indifferent locations. Considering workforce travel cost and time cost, a multi-skilled workforcescheduling optimization model was established to get the minimum total workforce cost, which isan integer nonlinear programming model. According to the characteristics of integer variables, themodel was linearized, and solved by means of ILOG CPLEB. Through a large number ofsimulation experiments with different parameters, the validity of the model was verified.
