A Trust Evaluation Method for Supplier Selection

Abstract

Trust and reputation systems play important roles in supplier selection, a topic that has been widely investigated from a business and operation point of view. However, we still lack of effective studies on supplier selection with security as the optimal target, which is a very important factor for Information and Communication Technology (ICT) systems. In response, this paper outlines a method that enables people to evaluate the relative and objective trustworthiness of the alternative suppliers. Our analysis is based solely on the original data of the vulnerabilities publicly available from OSVDB and NVD, which are impossible to tamper with. They are then interpreted by an approach that combines the Analytic Hierarchy Process (AHP) and objective analysis that enables the inference of relative trust valuations based on different evaluation indexes. A case study of five well known vendors is demonstrated with qualitative comparison based on visualization of data.

Review on Microencapsulated Phase Change Materials (MPCM) Slurries: Materials, Rheological Behavior and Applications

“…The common of core/shell materials are shown in Table 1. Overall, the main merits of microencapsulated phase change material (MPCM) over PCM are as follows: (1) increasing heat transfer area; (2) reducing PCM reactivity toward the outside environment and controlling the changes in the storage material volume as phase change occurs [5].…”
