Debasree has done her bachelors in civil engineering and masters in environmental engineering. She has completed her doctoral study in Waste segregation and treatment using Black Soldier Fly Larvae (BSFL). Her research interest is environmental engineering and specifically waste management as well as faecal sludge management.
Suitability index assessment for collection bin allocation using analytical hierarchy process (Ahp) cascaded to artificial neural network (ann) Debasree Purkayastha, Mrinmoy Majumder, Sumanta Chakrabarti Detritus, 2020 Municipal solid waste is an inevitable outcome of anthropogenic activities. Proper sustainable solid waste management is the need of the hour. In this study, a Suitability Index (S.I) has been determined which can measure the relative importance of a district with regard to its necessity or requirement of collection bins in comparison to other districts in a municipality. The S.I was computed using Analytical Hierarchy Process cascaded to Artificial Neural Network. Four criteria viz. Demographic, Social, Economic and Technical considerations and seven factors viz. Population Density (P.D), Street Width (S.W), Waste Generation Rate (W.G.R), Income Group Distribution (I.G.D), Average Minimum Distance between the bins (MIN.D), Available Number of Bins (A.N.B) and Cost of Waste Bins (C.W.B) were considered for developing the model. Available Number of Bins was found to have the highest impact on the model followed by C.W.B, W.G.R, MIN D., I.G.D, P.D, and S.W. This index will particularly help developing countries with resource constraint and unskilled labor force in Solid Waste Management. It will help such countries to easily locate districts in urgent need of collection bins with an easily available set of data and will help in increasing collection efficiency.
