STRUCTURE IMPROVEMENT USING ANT COLONY TECHNIQUE

The development of the Internet and the increasingly widespread use of it make the company more and more into e-business activities. In the ebusiness industry, a web site is the place where the company services are placed. So that the websites holds important role in the success of an e-business. Creating web sites that effectively and efficiently could increase user satisfaction, because they can find the information they want quickly and easily, or in other words to save time and costs. One way to increase the effectiveness of a web site is by improving the structures of its links. For site owners, improving structure may mean costs and time which is not small. Therefore, a right and efficient method for restructuring a web site is needed. One method that can be used is by using Quadratic Assignment Problem (QAP) approach. QAP used the graph concept to map the structure of web sites and to define the connectivity degree and relations between web pages. Then the QAP is used to modeling the page positioning problem. To resolve the problem, ant colony technique is used. Using the QAP method solved by ant colony techniques, new structures can be obtained and analyzed. From analysis we could know whether the new structure is better than old website structure or not from QAP objective function, closeness analysis, out degree analysis, and also best practices analysis point of views.
