一、问题的提出 我厂曾在研制EE3364型程控通用计数器的方案论证时,应用价值工程原理,取得了较好的技术经济效果。在此之前,曾研制了EE3366型等精度程控计数器,然而还存有以下问题: 1.采用进口元器件,不仅大大增加了外汇开支,而且无法立足国内形成生产能力和满足国内大多数用户的需求,更谈不上为工厂创造较好的经济效益。 2.成本费用高,维护费也高,多数用户无力购置。 3.虽然技术性能指标高,但对大多数用户,功能有过剩(少数科研单位除外)。 First, the problem raised Our factory once developed the EE3364 program-controlled general-purpose counter program demonstration, applied value engineering principles, and achieved good technical and economic results. Prior to this, EE3366 type equal-precision program-controlled counters were developed. However, the following problems still exist: 1. The use of imported components not only greatly increases foreign exchange expenses, but also cannot be based on domestic production capacity and meet the needs of most domestic users. Not to mention creating better economic benefits for the factory. 2. High cost and maintenance costs are high, and most users are unable to purchase. 3. Although the technical performance index is high, but for most users, there is a surplus of functions (except for a few research institutes).
