A Fuzzy Approach for Wieger’s Method to Rank Priorities in Requirement Engineering
Abstract
Prioritization helps to take good decisions according to various aspects of functionality such as risk, cost, maintenance, time etc. Prioritization decisions are made by stakeholders which include users, managers, developers, or their representatives. This paper focuses on proposing a fuzzy approach for Wieger’s Method to rank priorities in requirement engineering. This paper presents techniques of priorities in decision making. Wieger’s Method focuses on benefit, penalty, cost and risk as main factors in effecting of decision making. This method assigns weights for benefit, penalty, cost and risk. The previous factors are considered unclear and qualitative metric so using fuzzy logic to valuable in degree is more real and suitable. This paper proposed a framework which depends on resulting priorities for requirements with fuzzy Wieger’s Method, it results ranking priorities with fuzzy weights to benefits, penalty, risk and cost. Wieger’s Method using fuzzy logic compared to classical version is near to interest of stakeholder in importance each factor.
