Abstract

The role of learning curve in operations management has been an effective tool in estimating the operator performance level as the number of units produced increases. However, discontinuities in work disrupt the continual learning process, and a phenomenon called remission or forgetting occurs, resulting to increased time of performing the task upon resumption of work. The objective of the study was to identify variables that significantly affect the remission rate of sewing operations in a manufacturing setting. Two quantitative variables --length of stint 1, and percent difference at stint 1, and two qualitative or categorical variables--gender and product family, were identified. Length of stint 1 is the length of continuous performance (30 to 180 days). Percent difference at stint 1 is the change in processing time before the break relative to the average processing time of the first stint. A special type of work break was employed wherein other tasks were performed during the break. Gender was found to be an insignificant variable in predicting remission rate, while product family, length of stint 1 , and percent difference at stint 1 were statistically significant. Length of stint 1 had a moderately positive correlation with remission rate, while percent difference at stint 1 had a moderately negative correlation with remission rate. Also, percent difference at stint 1 was the largest contributor to the remission rate model. In terms of R2, the model is moderate. Furthermore, the model yielded an absolute error of 5.08%, indicating a high accuracy in predicting remission rate.
