Abstract:
This research is related to the performance measurement in the production processes of a texturing yam factory for use as an important piece of information for improving and increasing the production performance. The research began by surveying and collecting data from the opinions of the executives , engineers and supervisors of the case factory in order to specify factors that are important for production in terms of machine , man , materials , methods and production management. The researcher also developed the appropriate indicators of performance measurement from past researches and staff brainstorming. The importance of each factor was then ranked by the analytic hierarchy process(AHP). It was found that the machine performance played the most significant role with 36.7% of the all factors. The next step was performance measurement through the various indicators with the database system developed from MS Access software to measure the performance of the various production processes and for the entire factory. From the results , it may be concluded that the spinning process needed to be improved urgently because the performance indicators are distinctly lower than those of other processes. The researcher then chose to improve the machine performance by using methods study for reallocation of work to the operators resulting in the reduction of machine operating loss as the cage insertion operators quickened their works to take thread into the spinning machines and the spinning operators also quickened their works to join the ragged thread. The overall equipment efficiency (OEE), amount of good production / amount of staffs per day and amount of good production / total amount of raw material per day were increased with 99.99% confidence level. In conclusion, the introduction of the performance measurement system into an organization will be advantageous if it is used as information for continuous improvement.
