A Study on the Priority Selection for Information System Project Management Model
This paper focuses on the data reliability improvement of monitoring system in a steel manufacturing industry. The data obtained from the existing monitoring system is not the current micro data that reveals the current situation, rather it shows the average value (macro data) of between the current point and ending point. This macro data is not only difficult to analyze the factors causing errors, but also might have fatal influences on the quality of produced goods even the error is located within the tolerance level. Because the average value can be in the tolerance, but the maximum error value can be greater than the tolerance.
