| Abstract |
Productivity reduction factors(RF) have an important role in calculating productivity achievement ratio(PAR), an indicator for productivity evaluation. However, it lacks a detailed analysis for RFs and causes these three problems: (1) objectiveness of RF classification, (2) assumption of RFs as discrete variable, (3) dimness in RF controllability. Therefore, this study aims to analyze RFs using delphi method. In the process, 10 experts are selected to furnish expertises. Likewise, coefficient of controllability (CC), which is the coefficient indicating to what extends each RF could be controlled, is proposed to have an improved PAR model.??A case study is presented to show the implications of the model. This research can contribute to calculating more practical and precise PAR value. |
