Information technology (IT) system becomes increasingly significant as company grows in scale. Although many IT systems can be outsourced, there are still many systems that must be developed by the company itself due to confidential considerations. In addition, one major advantage of an IT system developed by the company is flexibility. Such a system can be easily modified to adapt to new environments, since the system developers are also the company’s employees. These conditions will provide better communication among departments of the company, and produce a much more customized system. This research considers a problem of manufacturing system integration faced by a TFT-LCD manufacturer in Taiwan. Management must identify which factors should be taken into account when integrating the current manufacturing systems, so that production and operational efficiency can be greatly improved. The research proposes a model combining analytic hierarchy process (AHP) and TOPSIS to evaluate three alternatives, namely A, B, and C, of integrating the manufacturing systems. In the model, the AHP criteria structure was constructed by collecting the opinions of the case company decision makers and the system users. After calculating the relative weights of the criteria, the system users are requested to provide their preferences on the three alternatives under different criteria. The results indicate that alternative A is the most favored, and the criterion “service quality” is superior to the other two criteria, “system quality” and “information quality”. As a consequence, the study recommends that the case company adopt alternative A as the framework to integrate its manufacturing systems, and should focus more on service quality.
