车间级设备维护管理系统的研究

A Study on Equipment Maintenance Management System at the Workshop Level

具体指入厂级、车间级和班组级环境安全教育。

It is divided into plant level , shop-floor and shift-group EHS education .

但是，到目前为止，我们尚未见到有关整个热处理车间级的计算机自动控制的报导。

We don find the report about computer auto-control for whole heat-treatment workshop up till now .

我们将实现上述目标的车间级生产管理信息系统称为制造执行系统。

We call the above-mentioned workshop level production management information system MES ( Manufacture Executive System ) .

对与生产活动紧密相连的车间级的成本管理与控制越来越受到企业的重视。

Enterprises pay more and more attention to cost management of workshop witch has closed link to production activity .

整个系统分三级：现场级、车间级、管理级。

The whole system is divided into three levels , namely field level , workshop level , and management level .

约束理论定位在车间级，负责车间或工段工序的日作业计划与调度、物料的投放；
