9. The mathematical formulation (1.1) – (1.6) of the production transportation problem uses the following notations: i  index for refineries (i = 1,2,……,I) j  index of petroleum products’ retailer / petrol pumps (j = 1,2,……,J) t  index for products (t = 1,2,………T) s  index for modes ( s = 1,2,……,S i , i = 1,2,…….,I) c is  Variable production costs for mode s at plant i c ijt  Unit transportation cost for product t from plant i to customer j a its  Quantity of product t produced at plant i by mode s b jt  Demand of product t by customer j; u ijt  A variable denoting amount of product t shipped from plant i to customer j z is  A variable denoting the intensity of using s by plant i
