| Summary: | 碩士 === 大葉大學 === 工業工程研究所 === 87 === Productivity, quality and flexibility are critical measures of performance evaluation for manufacturing systems. This project is to define, quantify and incorporate these three measures into a performance evaluation model for manufacturing systems. Productivity indicates the efficiency of converting inputs to outputs. In the project, different inputs of labor, material, capital, energy and overhead are defined and quantified to form productivity indices. Quality refers to the degree of perfection in marking products. Both levels of process and product are considered from the viewpoints of prevention and failure costs. Flexibility measures the adaptability to various changes in manufacturing environments. Three different types of flexibility measures are considered: equipment, product and market. Furthermore, these three measures are integrated to obtain an overall performance evaluation model in order to aid firms in measuring performance as well as in making investment decision on manufacturing systems. Finally, a case example is adopted to validate and illustrate the process and functions of the performance evaluation model being developed which incorporates productivity, quality and flexibility for manufacturing systems.
