Today, advancements in the information technologies increased the significance of electronic business in the world. Besides the numerous advantages provided by these advancements, competition has also increased for the enterprises. In this competitive environment, companies have to access information faster and response to the changes quickly.
In a supply chain, it is a highly possible that one of the partners may defect in providing its services. When these exceptional cases occur, the pending parties have to establish transitory collaborations to replace the missing partner promptly in order not to suffer this deficiency economically. Companies need to know the competences and capabilities of their prospective business partners before establishing partnerships. Furthermore, the reputations of the candidate partners have to be known to avoid possible regrettable partnerships.
In this thesis, we have developed a trust and reputation model that can be used over supply chains to determine and exploit the reputation of providers in transitory collaboration formation. The trust model takes the behaviors of providers, consumers into account and combines multiple criteria to aggregate a single reputation value. Experimental results show that, our model provides a robust and reliable reputation mechanism addressing a number of issues that have not been covered in the related studies.
In addition to this, an implementation of the model is realized within a Web application and the functionalities have been exposed as Web Services. The interoperability of the Web Services have been ensured through standard GS1 XML documents, which are utilized and extended in scope of the thesis. Furthermore, client interaction is provided through Web based user interfaces and REST services.
