water allocation of latian dam between agricultural products under uncertainty

چکیده
in the present study, water allocation of latian dam between agricultural products was evaluated by using inexact two-stage optimization model and the final results were compared to a fuzzy interval. data were collected from the regional water and agricultural organization of tehran province for 1991 to 2009 years. the results showed that by using interval fuzzy programming, 63%, 69%, 49% and 33% of water requirements of barley, agricultural products, vegetables and forage maize crops would be required at the best condition, respectively but the final amount of water allocated to wheat is not known accurately. also by using inexact two-stage optimization model in the case that water demand reaches to its lowest value, the system administrator works conservatively, and promises low water demand goal to the consumers. this will cause water shortage compared to the optimum condition. but when the target water demand reaches to the highest level, the manager put the water optimistically to the consumers. in this case, water shortage variable would increase in comparison to the optimum case. comparison of the two models showed that the inexact fuzzy two-stage optimization model simultaneously increases system profit and uncertainty.

Assessment of Final Value of Selected Agricultural Products under Water Economic Scenarios
T his research is an attempt to determine the agronomic plan, shadow price and final value with an emphasis on optimization of water use in five main agricultural regions of Kerman province (Kerman, Baft, Bardsir, Bam, and Jiroft) and five crops (wheat, barley, potato, onion, and tomato). Analysis was based on three scenarios: (i) current planting conditions, (ii) profit maximization...
متن کاملResource allocation under channel uncertainty
Scheduling policies in multi-queue multi-server systems need to allocate servers based on the channel state information and the queue state information. In the downlink, channel state information available to the scheduler may be imperfect due to feedback delay and estimation errors. Motivated by this, we consider the downlink scheduling problem of allocating servers to multi-queue multi-server...
متن کاملModeling irrigated agricultural production and water use decisions under water supply uncertainty
[1] Farmers make joint water and land use decisions for economic purposes based in part on water availability and reliability. A two-stage economic production model is developed to examine the effects of hydrologic uncertainty and water prices on agricultural production, cropping patterns, and water and irrigation technology use. The model maximizes net expected farm profit from permanent and a...
متن کاملOptimal Water Allocation: Sustainable Management of Dam Reservoir
Scarcity of water resources and huge costs of establishing new hydraulic installations necessitate optimal exploitation from existing reservoirs. Sustainable management and efficient exploitation from existing finite water resources are important factors in water resource management, particularly in the periods of water insufficiency and in dry regions, and on account of competitive allocations...

In this study, water management allocated to the agricultural sector’ was analyzed using stochastic dynamic programming under uncertainty conditions. The technical coefficients used in the study referred to the agricultural years, 2013-2014. They were obtained through the use of simple random sampling of 250 farmers in the region for crops wheat, barley, melon, watermelon and ruby grapes under ...
