Abstract: This paper introduces a method for evaluating material and product quality. The method is developed based on the normal distribution. For quantitative variable, the method divides the tolerance zones to 3 parts according to normal distribution ±3𝜎 and assigns different scores to tolerance region. For qualitative variables, the method take decision base on the fact that the measurement result can be occurred on two states as accept or reject. Therefore, a Level of Quality (LOQ) will be measured for the product quality based on the measurement of different samples of lot by quantitative and qualitative variables. The method is validated by a numerical example included 2 dimensions.

Abstract: Random third party quality audits are mandatory by the regulations for public construction projects in Taiwan. This project and auditor selection process is a difficult work assignment problem because there are normally hundreds of projects and dozens of auditors to choose from. The purpose of this research is to establish a genetic algorithm based model to assist with the project selection and auditor assignment process. The model is set up to find the optimal match between the project characteristics and auditor expertise from approximately 5.09E+29 possible combinations. Information provided by the Kaohsiung County Government is used to test the model. The results show that the model is not only valid but also able to produce a “much better match” between projects and auditors when comparing to manual assignment.
