ABSTRACT There is a need for mathematical tools in order to manage the municipal solid waste and thereby providing a healthy environment to the society. The transportation problem is a special class of the linear programming problem. It deals with the situation in which a commodity is transported from Sources to Destinations. The transshipment problem is an expansion of the transportation problem where intermediate nodes which are also referred to as transshipment nodes are added to account for locations such as warehouses. The flow of waste from the source spot through processing spot to the destination spot has been formulated alternatively as a transshipment model. The main objective of this paper is to model solid waste management as a transshipment problem and also minimize the cost in transporting them. Transshipment problem has been formulated to a Transportation problem algorithm and TORA Software has been used to analyze the data. If Nagapattinam municipality adapts this method, the cost of transporting waste will be minimized also the waste will be processed in the processing plants and its by- product will be used in the market and the total quantity sent to the dumping yard will be reduced which will help in increasing the life span of dumping yard.
