寻找针对项目目标的系统性能评价方法与确定项目目标本身一样重要。通常情况下,当人们产生新的仪表或自控系统的需求后,就会开始购买必要的设备产品,然后安装,投入使用,当一切进入正常运行轨道后,工程人员就开始着手下一个项目了．这似乎是顺理成章的。但事实上事情并不总是那么简单——很多时候,我们还需 Finding a system performance evaluation that addresses the goals of the project is just as important as setting the project goals themselves. Oftentimes, when people create new instrumentation or control system requirements, they begin to purchase the necessary equipment for installation, commissioning, and commissioning. As soon as everything is on track, engineers begin the next project. This seems to be logical. But in fact things are not always that easy - many times we need it
