Szukana fraza: [Abstrakt = "The conventional linear programming based transportation model in the previous studies was examined and found to be deficient in practice. Modified transportation model has been developed to include some predetermined salient factors such as road safety and security. In the real sense these factors are accidental and they can occur without prior notice. Besides, weather change is also critical to transportation insecurity. In this paper a new transportation scheme’s model was deve\- loped to take into consideration the incidental occurence nature of the insecurity factors as applicable elsewhere. The weighted loss cost function due to the insecurity factors on roads was formulated using Analytic Hierarchy Process \(AHP\) and its outcome was integrated into the conventional transportation model. The cost savings from three models namely conventional, modified\-conventional, and the current \(re\-modified\) were compared using the petrol’s transportation schedule of the Nigerian petroleum industry. The results showed that the re\-modified transportation model was not in good agreement with the other two in term of flexibility. The findings showed that the cost price of the item has a wide margin depending on the incidence and the weight of insecurity."]
