指出常用选型方法的不足,提出应用模糊数学评价选择设备的方法,详述了评价方法及应用实例。对影响设备投资效益(寿命周期费用)的各个因素,诸如生产效率、精度、价格、可靠性、适用性、维修性和安全性等,应用模糊数学方法进行评价,所得到的结果不是如常用方法得到一个数字,而是一个 The shortage of common selection methods is pointed out. The method of applying fuzzy mathematics to evaluate selection equipment is proposed. The evaluation methods and application examples are described in detail. The factors affecting the investment efficiency of equipment (life cycle cost), such as production efficiency, accuracy, price, reliability, applicability, maintainability and safety, are evaluated by using fuzzy mathematics method. The results obtained are not as usual methods Get a number, but one
