Since the management team decided to assess the effective factors on the quality of the welding in the manufacturing process by utilizing simulation, we have to briefly describe the used simulation process called Design of Experiment (DOE) and understand the characteristic of such analytical process.
Basically, the process of accumulating the data based on the observations is time-consuming and costly and miscalculation in the return of investment on the improvisation can be harmful to the organization. Therefore, different types of analytical software were developed as alternative tools to assist the companies to examine their hypothesis about the assumed issues on simulated platforms. Using such simulating programs in a Six Sigma process are called Design of Experiments (DOE). DEO is used to detect cause-and-effect relationships and put them in the statistical examination to find the significant parameters in order to take a proper measure to improve the process. …show more content…
Determining the critical factors usually takes place through accumulating the voice of customer(VOC) but in this case, the risks associated with the process were the determining factors in welding. Critical parameters (YS) is directly related to the success of the welding process and considers to be the dependent variable and the controllable factors (XS) are the independent variable. In addition, a factor of noise (n’s) that could be effective on the critical factors is also taken into account. Assigned team found the important factors effective on the quality of laser welding as following:
• Invar thickness
• Copper thickness
• Epoxy thickness
• Epoxy modules of
