    Multi-Objective Optimization Model for Irrigation Water Allocation
    (ASIAN JOURNAL OF MATHEMATICS AND APPLICATIONS, 2018) Fanuel, Ibrahim; Mushi, Allen
    In Tanzania, management of land and water resources is considered an ab- solutely strategic priority for agricultural development. In this study, a Multi-Objective optimization (MOO) model was formulated to utilize the available water by identifying the best crop patterns which maximize the farm total net bene t and minimize the total vari- able costs. The data for 6 crops collected from Nkoanrua region and FAO were used for the model analysis. The Subdivision Algorithm which is a set oriented numerical method was used to analyse the model. After 54 subdivision steps, the model proposed that, the amount of land allocated to crops which are less pro table depends on the minimum requirement constraints, while, for more pro table crops, the allocation is based on costs of production, minimum and maximum requirement constraints, Bene t, and water requirements. Lastly, the sensitivity analysis shows that, the price and production costs for carrots and maize has no impact on the model solutions.
