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...

We propose a model of winners allocation. In this model, we are given two elections where the sets candidates may intersect. The goal is to find disjoint winning committees from respectively that subjected certain reasonable restrictions. For our first several desirable properties. Then, investigate implication relationships among these Finally, study complexity computing allocations providing ...

credit allocation through the usage of portfolio optimization mainly seeks tomaximize return and minimize the risk of the portfolio; but there are other importantissues including sustainable development which is important for government/publicsectors. this paper presents a novel credit allocation approach based on portfoliooptimization and investigates the effects of selected indicators of sust...

introduction: in spite of improving the water productivity due to development in water infrastructure systems, population increasing causing the water withdrawal is triple in the last fifty years. in this situation competition on water consumption especially in the agricultural sector which is the biggest consumer in the world and also in iran is a severe problem. water allocation has been asse...

development projects in natural water resources like rivers and lakes, specially transferring water to use in agriculture, domestic and industrial sector without considering environmental values, causes irrecoverable and irreversible damage to ecosystem and future options. if we consider the future generation and species rights, those damages and costs can be very much than we take in. the abov...

Background: The construction of metro lines is a high-risk project. Using a budget-based model for the safety units of metro construction projects can help safety managers to spend optimal budget allocation. The purpose of this study was to plan a budget model based on safety unit performance in an under construction metro station for better budget allocation using robust optimization. Methods...

Today the most organizations (e.g. banks and insurance institutes) consist of the various units which under the control of the main organization (unified management) act independently. Sometimes the manager presents some services which incur costs such as advertisement and introducing a new technology. Most organizations consist of several individual units. Resource allocation issue appe...

With the rapid growth of wireless access networks, various providers offer their services using different technologies such as Wi-Fi, Wimax, 3G, 4G and so on. These networks compete for the scarce wireless spectrum. The spectrum is considered to be a scarce resource moderated by the spectrum allocation regulatory (“regulatory” for short) which is the governance body aiming to maximize the socia...
