| dc.description.abstract | The chemicals and poisonous gases in the semi-conductor factories are getting more diversified and complicated, so more and more details are concerned. If leakage accident occurs, it will diffuse and impact the physical health of all personnel nearby. Thus, the plant must be equipped with gas leakage sensors, which should have the functions of synchronous detection and real-time alarming. Moreover, it must confirm the value read on the sensor is accurate and reliable, or it may cause greater loss due to the false alarming. Therefore, the sensor should be conducted with calibration periodically. In practice, such calibration operation is usually performed by the manufacturer, and the calibration assignment is arranged based on the experience. The calibration personnel are assigned based on the vendor’s contractual terms and the existing resources. It lacks overall consideration based on systematic and scientific analysis, which may easily result in uneven distribution and unfairness in terms of the calibration personnel, calibration quantity, and operation region.
In view of this, to resolve above problems, the study uses the mathematical linear 0-1 integer Programming method to set the requirements and limitations for assigning the calibration personnel, and finally work out a mathematic integer planning model applicable to optimizing the calibration personnel assignment. It inputs various parameter data and outputs the execution results by using Office Excel 2007, and then calculates the solution by using LINGO12.0 software package. Besides achieving the purpose of assigning calibration personnel fairly, it can also help the decision-makers perform assignment and planning more efficiently. Moreover, the parameters can be adjusted or set based on different manpower or limitations, so as to re-plan and adjust the assignment of calibration personnel. | en_US |
