Spinning 작업자의 적정담당 대수와 생산성에 대한 통계적 고찰 = (The) Statistical Evaluation of the Spinning Machine System Efficiency in Optimal Varrying Machine

다국어 초록 (Multilingual Abstract)

In the multimachine assignment problem, Jones calculated the machine interference and the operator interference assuming the frequency of machine breakdowns of Bionomial distribution, and wright formulated the machine interference model distribution.
In this study, it was statistically proved that the spinning machine breakdowns at any random moment and spatial location takes the poisson distribution.
A case study was made in the of the leading textile firms in Korea Pusan.
The results are follows ;
(1) machine interference is 2.6 percent, operator interference is 29.9 percent.
(2) operators performance rate is 109 percent by operator interference and 0.34 machine is always breakdown states at any moment by machine interference rate.
(3) 100% performance rate operator varrying 15 mach ines and 50% performence rate operator varrying only 7.7 machines, 120% operator varrying 17machines.
(4) Alternative methods in system improvement and cost reduction are discussed and suggested.
