目前,我国进口工程机械总量估计已达七、八百亿美元,而且品种繁多。备件供应成了施工部门的沉重负担,每年仅购买进口备件要花费几亿美元。因此,备件国产化问题急待解决。用设备综合工程学研究备件国产化问题,就要着眼于全系统和全寿命。从全系统观点看,各部委分别抓备件国产化是不对的。不仅力量分散,而且有很多重复劳动。应该有一个机构 At present, the total amount of imported construction machinery in China is estimated to have reached 70 to 80 billion U.S. dollars, and there are many varieties. The supply of spare parts has become a heavy burden on the construction department. It costs hundreds of millions of dollars to purchase imported spare parts every year. Therefore, the problem of localization of spare parts needs urgent solution. With the comprehensive engineering of equipment to study the localization of spare parts, it is necessary to focus on the whole system and the whole life. From a system-wide perspective, it is wrong for each ministry to focus on the localization of spare parts. Not only is the power scattered, but there is also a lot of duplication of effort. There should be an institution
