Abstract
|
|
|
A work place comprises men, machines, and the environments surrounding it.
Roughly speaking, it may be said that goods are produced under a correlation between men, machines, and materials.
In this survey, we have examined the direct and indirect influences on productivity of various factors affecting productivity and human ability, including work hours, holidays, rest, absence rates, temperature, noise, dust, etc.
In general, in some important part of the whole manufacturing process which requires a large amount of labor, the productivity is greatly and directly affected by labor capacity when the labor capacity is contingent on work conditions or work environments. However, in the case of an automatic manufacturing process, the productivity is not nuch affected by the influence of labor capacity which is variable depending on work conditions and work environments. For example, the workers on duty in the lst transformation process in a urea fertilizer plant and those watching the calcination furnace in a cement factory have to keep watching meters under high radiant heat. Accordingly, their labor efficiency is affected, but their affected labor efficiency has scarcely direct effect upon the productivity. Of course, high temperature may be considered one of the factors adversely influencing upon productivity because it serves an indirect cause of a high absence rate as well as a high accident rate.
On the other hand, since the rolling process in steel industry requires a great deal of physical labor, the radiant heat generated in this industrial process affects directly industrial efficiency and, accordingly, adversely and greatly affects the productivity.
