实验室单台设备维修更换模型

The Model for Maintaining and Replacing Laboratory Equipment

运用运筹学的原理与方法,建立了实验室单台设备维修更换的数学模型,它能容易地确定每台机器预防性更换的最优间隔期,从而使设备在单位时间内的预期更换代价最低。

Operational principles are employed to set up a mathematical model for a unit laboratory equipment needing maintenance and replacement, which can determine the optimum interval of replacement in case of their breakdown, thus saving cost of replacement.
