Interval Evidential Reasoning Algorithm for Requirements Prioritization

A good requirements prioritization technique is one which involves all the relevant stakeholders, provides them the flexibility of assessing a requirement by means of subjective and uncertain inputs, and aggregates these assessments to produce reliable requirements priorities. This paper addresses this by applying Interval Evidential Reasoning (IER) algorithm. Analytic Hierarchy Process (AHP) is employed to determine the varying contribution of stakeholders. The degree of satisfaction with the requirements priorities will be obtained by following the same procedure followed for requirements assessment and aggregation.
