dc.description.abstract | In the traditional construction industry, the auditing of implementation effects w.r.t. construction quality, financial control and management, and safety and health of an engineering project is usually conducted spontaneously by each single company. To make effective quality systems in departments, the institutionalization of annual internal auditing mechanism has become one primary concern due to the enactment of the Operating guidelines for Public Construction Quality Management in 1996 by the Public Construction Commission of the Executive Yuan and the encouragement of acquirement of ISO (International Organization for Standardization) certifications.
Take company N for example; in order to have good understanding of implementation effects of its departments, an audit team, in its headquarters, was set up through random membership assignment for the task of internal auditing each quarter. However, the assignment of auditing manpower practically depends upon the management’s experiences, which is deficient in either systematical or scientical grounds and thus leads to drawbacks of, for instance, unfair assignment of manpower, time wasting, slow job progress, etc.
To satisfy particular demands and prerequisite conditions for the assignment of auditing manpower, this study develops an optimal assignment model using integer regression, where the LINGO (ver. 8.0) software is adapted for problem solving. The proposed model not only attains to the aim of fair assignment of manpower, but also is adaptive to reassign tasks to auditors based on parameters set for different situations. The model was evaluated with company N as a case study. Experimental results demonstrate that the proposed model is superior to traditional methods using heuristics in terms of the fairness and the efficiency of manpower assignment. In addition, it is suggested that small business could benefit from the model in practical assignment of manpower.
