ABSTRACT
As E-government continues to develop with ever-increasing speed, the requirement to enhance traditional government systems and affairs with electronic methods that are more effective and efficient is becoming critical. As a new product of information technology, E-tendering is becoming an inevitable reality owing to its efficiency, fairness, transparency, and accountability. Thus, developing and promoting government E-tendering (GeT) is imperative. This paper presents a hybrid approach combining genetic algorithm (GA) and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) to enable GeT to search for the optimal tenderer efficiently and fairly under circumstances where the attributes of the tenderers are expressed as fuzzy number intuitionistic fuzzy sets (FNIFSs). GA is applied to obtain the optimal weights of evaluation criteria of tenderers automatically. TOPSIS is employed to search for the optimal tenderer. A prototype system is built and validated with an illustrative example from GeT to verify the feasibility and availability of the proposed approach.

pone.0130767.g007: Graphical interface for setting evaluation criteria.

Mentions: After inputting the basic tenderer information, the government-tendering sector must define the evaluation criteria (see top of Fig 7) including the criterion name and comment, e.g., the lower the better or the higher the better. Then, clicking the “Add criterion” button presents a set of evaluation criteria as indicated in the Fig 7 window. In this example, there are five evaluation criteria including “function”, “artistry”, “safety”, “feasibility”, and “price”. The “overall rating” criterion represents the overall ratings of experts on the 12 candidate tenderers. The input information can be modified or deleted, if necessary.
