This study is a pilot study on the contribution of measurement-related investments Analyst, 97. 29-35 made by 78 Korean heavy Chemical industrial firms. The classification of investigated firms is made according to enterprises vs. Small/medium-size firms, firm with standard measurement facilities vs. 44, 695-698 (1972). firms without such facilities. Thus these firms are analyzed and compared statistically by year.
This study aims at illuminating the effects of precision measurement-related investment on the reduction of products error rates.
This investigation shows that the measurement-related. investment has a direct effect on reducing percent of defective products.
However, owing to the limited. number of investigated industrial firms, it is further needed to enlarge the scope of investigated firms and verify statistical reliability of respective, mean values.
1) From the view point of micro-economic effects, in the firms which have positivel,, invested for the measurement, the inferiority ratio of measurement apparatus has been decreased. The infer iority ratio of measurement apparatus affects the inferiority ratio of the products themselves. The inferiority ratio of a firm, for example, has decreased by 32% of that of last year.
From the business recognition point of view, 53.6% of the firms with the measurement standard division report a large amount of expense decrease. Other firms, however, report only 10.5%.
This result shows that the more a firm invests to measurement the less deficit due to interior goods it has. It is analyzedthat´the firms which do not invest in the area have a large amount of inferiority deficit.
2) According to the present result, it is shown that the measurement related investment may decrease the price cost by decreasing the production cost ofthe individual manufacturing firms. It is also shown that the measurment investment can increase the competitive power of price by increasing the productivity of goods, particularly, the investment may prove the quality of goods by cutting down the inferiority ratio of the manufactured goods.
It is statistically proved that there is a close relationship between the amount of measurement investment and the inferiority ration of products in manufacturing companies.
