本文的研究对象是一个日产10吨恒粘胶和日产8吨20号胶的三班制标准胶厂。工厂投产已将近十年。到目前为止,工厂一直实行于损坏后修理的方针,也即是等零件彻底损坏后再更换。现在要问,这个工厂是否值得执行预防性保养计划? The object of this study is a three-shift standard rubber factory with a daily production of 10 tons of constant viscose and 8 tons of 20-day plastic. The plant has been in production for nearly a decade. So far, the factory has been implementing the principle of repair after damage, that is, when the parts are completely damaged and then replaced. Now we have to ask whether this factory is worth implementing a preventive maintenance plan.
