Abstract
The study determines least cost distribution system for locally produced maize transportation. The study uses the transportation problem, an application of the Linear programming Technique, where the total transportation costs are minimized subject to demand for and supply of maize. and the TRC railway wagon capacity constraint, The sources of supply are those regions which are net surplus producers and the destinations are the net deficit regions. Only interregional flows are considered. From the model we found, minimum cost as 99, 324, 887.07 shillings. The NMC actual cost is 110,576, 665.9 shillings. Our figure is lower than the NMC by 11 , 251 , 773. 2 shillings. We therefore concluded that the model split and pattern of distribution we used, could have been more economical if it had no limitations like pilferage, time delays and seasonality of roads. We recommend the use of the combined mode of the railway and road which is a relatively lower cost mode.
