Application of Analytical Hierarchy Process (AHP) for Assessment of Collection and Transportation of Solid Waste: An Empirical Study

Abstract

Cities and Urban Local Bodies (CULB) are considered to be the engines of economic growth and any significant improvement in their operational efficiency will lead to a positive impact on the economy. The major portion of expenditure on Solid waste management (SWM) of CULBs is spent on waste collection and transportation activities. To enhance the efficiency of SWM, it is essential to collect and transport solid waste in a scientific manner. As a result, systematic solid waste collection and transportation will effectively resolve and improve SWM concerns. In this paper, Analytical Hierarchy Process (AHP) method is adopted to appraise various alternatives of solid waste collection and transportation methods of municipal solid waste in Visakhapatnam city, India. The additive normalization method is applied for calculating the criteria weights. The fairness of judgment is checked by the consistency ratio. To calculate AHP accurately and fast, a decision support system was built. The findings of the study will be beneficial in evaluating existing solid waste collection and transportation processes to improve the operational efficiency of managing SWM.
