The Confirmatory Factor Analysis of Enhancing the Warehouse Management Efficiency in Map Ta Phut Industrial Estate, Rayong

Abstract

The purposes of this research were 1) to analyze the confirmatory factors of enhancing the warehouse management in Map Ta Phut Industrial Estate, Rayong Province, and 2) to verify the tests based on the consistency between the confirmatory factor structure of enhancing the warehouse management in Map Ta Phut Industrial Estate, Rayong Province and the empirical information. The sample group was 400 warehouse employees in Map Ta Phut Industrial Estate, Rayong Province with simple random sampling. The research instrument used was the questionnaire with item objective congruence (IOC) index of 0.99. The statistics used were frequency, percentage, mean, and standard deviation (S.D.), exploratory factor analysis (EFA), confirmatory factor analysis, and second-order confirmatory factor analysis. The data were analyzed by simple statistics: percentage and standard deviation. The results of the study found that the efficiency enhancement of warehouse management in Map Ta Phut Industrial Estate, Rayong Province based on the POLC theory of Louis A. Allen. The principles of management can be distilled down to four critical functions. These functions are planning, organizing, leading, and controlling. The results of the first-order confirmatory factor analysis found that all the indexes passed the criteria. The Chi-square minimum probability (CMIN/P) was 0.108, the Chi-square minimum discrepancy per degree of freedom (CMIN/DF) was 1.137, the goodness of fit index (GFI) was 0.98, and the root mean square error of approximation (RMSEA) was of 0.02. The factor loading was between 0.90 and 0.98 at the statistical significance level of 0.01. Lastly, the factor loading ranged from the highest to the lowest as follows: organizing, planning, controlling and leading, respectively to be the guidelines for the enhancement of warehouse management efficiency in Map Ta Phut Industrial Estate, Rayong Province.
