Overview of cost-minimization analysis as mentioned in chapter 1, cost-minimization analysis (cma) measures and com-pares input costs, and assumes outcomes to be equivalent. Total transportation cost is minimized while fulﬁlling all supply and demand limitations network representation of time minimization transportation problem. 230 network models 82 the transportation problem expression (1) represents the minimization of the total distribution cost, assuming a linear cost structure. For most supply chain and logistics operations there is an opportunity to reduce cost by 10% to 40% by making better decisions high-demand transportation. The function is called, variously, an objective function, a loss function or cost function (minimization), a utility function or fitness function (maximization), or, in certain fields, an energy function or energy functional.
In a cost minimization problem, the cost of transportation depends on the quantity shipped to the contrary, in a time minimization problem, the time involved is independent of the amount of commodity shipped. Transportation cost is one of the major costs incurred during operations in courier service industry their profit margin depends purely on transportation cost. Of delivery of product to markets have become crucial, the pressures for cost minimization are transforming transportation, storage and handling practices moreover, the increasing trend in.
An optimal solution of the max-min sum minimization transportation problem is one for which the sum of these two values is the least as at most a ﬁnite number, say ( g + 1)( p ). Equation (a) is the minimization of the product of cost and amount of product, which gives the total price the total price is subject to the constraints of equations (b) and (c), where (b) is the condition that the sum of the products transported from source to demand is not greater than the total supply. Destinations while minimizing total transportation and production costs 3) 4) the transportation algorithm can be used to solve both minimization problems and maximization.

The hitchcock-koopmans transportation is linked to the gravity 'model' of regional analysis with the aid of two new analytical results eighty transportation problems are generated by monte carlo methods and solved by linear programming. The expert examines cost minimization 400) is less than supply(450), this is an unbalanced problem 3 to warehouse 4 at total transportation cost of $770.
