Allocation of construction risks between clients and their contractors has a significant impact on the total construction costs. This paper presents a system dynamics (SD)-based approach for quantitative risk allocation. Using the proposed SD based approach, all the factors affecting the risk allocation process are modeled. The contractor’s defensive strategies against the one-sided risk alloca...

abstract among different water usage in iran, agricultural sector with 94 percent is the largest water user. considering the share of agriculture in water usage, farmers are the main factor in water resources management. therefore, optimal utilization of irrigation and drainage networks would depend on farmers’ effective role. due to the limited water resources in different country regions, inc...

In this paper, a two-stage fuzzy random programming for a management problem in terms of water resources allocation having fuzzy random variable coefficients and decision vector of random variables is studied. The first results show the fact that a fuzzy pseudorandom optimal solution of a two-stage fuzzy random programming may be resolved into a two of pseudorandom optimal solutions of relative...

in this study, a model of optimal allocation of subsidy was developed based on the microeconomic optimization theory. the model was evaluated by applying to premium subsidy allocation to the cereal crops’ (corn, rain fed barley and wheat, and irrigated barley and wheat) insurance in iran. in developing the model, it was assumed that, policymaker on behalf of society, follows a social utility ma...

[1] The adjustment of local vegetation conditions to limiting soil water by either maximizing productivity or minimizing water stress has been an area of central interest in ecohydrology since Eagleson’s classic study. This work has typically been limited to consider one-dimensional exchange and cycling within patches and has not incorporated the effects of lateral redistribution of soil moistu...

Water and fertilizer applications management should be improved due to scarce resources and environmental protection aspects. An analysis of crop yield production and profit maximization was conducted to determine the optimal water and nitrogen allocation. In this study, maize grain yields were predicted for 25 different amounts of irrigation water (350-1700 mm) and 46 different rates of nitrog...
