배합 압축작업에 있어서의 동작 시간연구 = Motion and Time Study in Mixing and Pressing Operation

다국어 초록 (Multilingual Abstract)

In this thesis I tried to research a motion and time study in mixing and pressing operation of a manufacture in Korea. On this thesis I would like to summarize as follows: (1) The motion and time study have been found as an important element, also in the under-development of industrial management in our country, therefore we are in a position to suggest several important policies for the improvement to the management, according to the research of this kind. (2) A general, instead of partial, observation is needed in order to determine the base time of the operation in this kind of enterprise. The general observation is an average of the observations on every specific time-usually one hour-through all operating time in a whole day. (3) The base time of the pressing operation was observed as follows: the average one: 5.69 second the longest one:6.28 second the shortest one: 4.53 second (cf. table 27) (4) The average allowance percentage of the pressing operation was observed as follows: Job allowance: 18.5% Personal allowance: 1.0% Fatigue allowance: 5.7% Process allowance: 26.1% Total allowance: 51.3% The longest one was 84.5% and the shortest was 40.0% in total allowance percentage. (cf. Table 128) (5) Both the base time and the allowance percentage of the operation in night time was a little longer than in day time operation.(cf. Table 17. 18. 19. 139. 141. 142) (6) If the incentive wage plan will be adopted, and the operation will be improved by determining the standard time and the task according to this time study, the products will not be decreased even though the labour time would be shortened to a certain extent, and therefore they will able to promote the operation and good effects to both of employee and employer.
