| Popis: | 97 The most advantageous tendering (MAT) method, which has been adopted for years in Taiwan, is one of the multiple-criteria decision procedures for contractor selection. Recently for public construction there is a tendency toward large-scale, in this condition multitudinous characteristics are involved. Due to the intense competition on construction market, both academic and businessman are most concerned to build a proper contractor selection procedure based on individual project characteristics to satisfy owner’s demand. The purpose of this paper is namely to integrate academic and commercial procedure and then propose a model of contractor selection decision for MAT which conforms to the spirit of laws and regulations and is applicable to projects with different characteristics. The major contributions of this paper include two parts, the contractor selection model and bid price evaluation for MAT. First, the study on the contractor selection is based on the traditional AHP method but adopts the genetic algorithm (GA) to derive the adaptive AHP approach (A3). Differing from traditional AHP, this approach is more efficient in generating criterion items and their relative significance value for further scoring and ranking since the re-interview procedure of policymaker in tradition AHP is replaced. Next as regards the bid price evaluation, the item price is also considered in the evaluation. The concept of utility value is applied to linearly transform the total price and item price into corresponding scores to obtain final scores for further grading. This method is an indeed application of academic research to solve practical problems thus any acquired experience and knowledge in this paper is absolutely referable for future application. In conclusion, in this paper the A3 is used to calculate the relative significance value of each criterion item for the contractor selection of MAT instead of the traditional AHP. Achievement of the adaptive AHP cooperated with familiar scoring method is not only conformable to laws and regulations but it is also more beneficial on time, cost and quality than traditional AHP. Furthermore, the proposed bid price evaluation model makes the outcome of whole multiple-criteria decision procedures more impartial and objective. |
