| dc.description.abstract | Some times there may be many di®erent ways to model a particular problem, choosing the best one minimizes the complexity of the problem and time to solve. Since, as we have said earlier, any programming problem with constraint matrix structure the same as the transportation problem is regarded as a transportation problem regardless of it's physical meaning and because of it's simple structure, modeling problems as transportation problems requires much less e®ort to solve than that of modeling it di®erently. In this thesis the nonlinear transportation problem is considered as nonlinear pro- gramming problem and algorithms to solve this particular problem are given. The ¯rst algorithm is similar to that of the transportation simplex algorithm except the nonlinearity assumption. The second algorithm is dependent on the simplex algorithm of Zangwill [32] that we modi¯ed it to use the special property of the coe±cient matrix of the transportation problem so that we may take shortcuts to make problem solving simple. However the algorithms are not been compered to other previous algorithms. Therefore in the future further work must be done : 1. To measure the e±ciency of the algorithm. 2. To check how near the solution of the approximated problem of the piece- wise linear transportation problem is to the optimal solution of the original problem. And ¯nally 3. to implement the algorithm to the real world problem. | en_US |
