Abstract
This chapter describes the interface design and the applications of a web based assessment tool on the basis of the Evidential Reasoning (ER) approach. The tool has been validated and used by a number of business users and examples of the application areas include business innovation assessment, supplier evaluation, and performance assessment. The ER approach is developed to handle multi-criteria decision analysis (MCDA) and assessment problems possibly with hybrid types of uncertainties. It uses belief decision matrices for problem modelling and data collection. Combined with thoughtfully designed interfaces, the tool offers a flexible and friendly environment for web users to express their assessment judgments consistently, objectively and accurately. By applying the ER algorithm for information aggregation, assessment outcomes generated from the tool can include average scores and ranking, sensitivity of the outcomes to uncertainties in different parameters, distributed assessments revealing variations in performances, and user specific reports highlighting key areas for attention. The interfaces of the tool allow users to enter data using a built-in assessment criteria hierarchy and to display aggregated outcomes in both text and graphic formats.
