Rp-Using transportation problem under uncertainty environment through Classification periods with an application.pdf

In this study we focus for the one of the important Opp roof transportation problems from supply demand into the sources The interest in this study focuses on how to transport and distribute petroleum products from distribution centers, which are a number of refineries distributed in different locations. This includes a group of governorates that consume these derivatives. In this case, the usual and multi-stage transportation models (Multistage Transportation) are adopted in order to accomplish this task. As the decisions to transfer these derivatives are made in the Iraqi environment characterized by a state of uncertainty (Uncertainly) and appear here. A certain peculiarity of this transportation process is that there is a temporal classification of the processing process for this substance (white oil), as it turns out that there are three time periods
1. The winter period, which is when the use of white oil in heating is very high. This period extends from 11/1 to 31/3.
2. The period of the lowest level of use, which is the period during which temperatures rise in Iraq or the summer period from 1/5 to 1/11.
3. The spring or fall period, which is approximately no more than one, two, or three months.
A set of conclusions and recommendations were made, the most important of which are:
Adopting mathematical transportation models in the process of transporting and distributing petroleum products, especially white oil, would enhance the scientific technical capabilities in the process of transporting and distributing white oil at the lowest possible total cost.
