Optimal crop planning model for an existing groundwater irrigation project in Thailand

摘要: Abstract A monthly irrigation planning model is formulated for determining the optimal cropping pattern and groundwater abstraction requirement in an existing development project. Two objectives, maximisation of net economic benefit irrigated area, aspired to by both authority individual farmers Sukhothai Groundwater Development Project Thailand are considered. To account uncertainty water resources availability, solved three levels reliability rainfall (80, 50 20%). The effects deficit on intensity as well yield crops also assessed considering (no deficit, 25% 50% deficit) application crops. select best alternative plan, a multi-objective analysis carried out using Analytic Hierarchy Process preference decision makers, including project managers. selected makers collectively allocate almost half total weight (or risk) factors, while remaining equally divided between two objectives listed above. On average, they seem prefer corresponding average (hydrologic) conditions full without any deficit.
