Szukana fraza: [Abstrakt = The traditional linear programming model based on transportation system model seems impracticable in developing countries because of neglect of certain salient environmental factors such as deplorable state of road safety and security maintenance. A transportatioin system model is de\-veloped by taking into consideration the identified environmental constraints. The severity of the road safety and security deplorability was measured from pot\-holes generation and check\-points mounting rate. The loss cost function due to this deplorability was formulated and its outcome was integrated into the traditional transportation model. Transportation schedule from depots to the retail stations of the petrol product of the Nigerian petroleum industry was used to test the efficacy of the model. The results showed that the new scheme was not in good agreement with the traditional approach in some test cases. The findings showed that the cost price of the item can be affected by the degree of deplorability of road safety and security maintenance.]
