- As many researches focused on application of robust design engineering in practical case study, very less concerned on the criticality to data measurement system in parameter design. This paper will emphasize on the importance to be critical to data obtained during experiment. The existence of outliers is often ignored and the impact overlooked, thus endanger the results by producing false alarm and giving completely wrong parameter setting. The optimum condition from the data that contains outliers is compared with the corrected data measurement. The finding presents the indication procedure on how to confirm whether the data is reliable or not for evaluation. The data is unreliable when two main indicators are detected. Firstly, the measurement data plot detects outlier through linear regression analysis as it does not belong on the linear line. Secondly, poor reproducibility presented by estimation and confirmation of signal-to-noise ratio. This failure affects the experimental design and lead to wrong optimum condition. T-peel adhesion test using orthogonal array L9 is done as a case study to elucidate the detection of outlier and outlier effect on optimum condition.

- This paper proposes an object-oriented design for generating Stock Keeping Unit coding system. Through recognition and analysis of the inventory item particulars and conceptualizing the important classes as one package, the framework is developed in a modular-basis able to be integrated with other parts of the system. Using UML class and package diagram as of the best practice in object-oriented, conducting the analysis and design is elaborately discussed. A prototype implementation is carried out to support the designed framework over its applicability at a modular information system. Moreover, the item particular package with unique and organized SKU numbering system efficiently supports the fundamental need of item identification at inventory control operations and classification and guarantees different types of reports and lookups.
