In a framework similar to the models of expectation on economic policy, we purpose a model where the government subsidizes firms privatized by massive giveaways to the managers who are empirebuilders. The government injects funds because its aim is to avoid a drastic fall of output when a negative external macroshock hits the country. The consequence is that the economy can be locked into a sof...

from among the major problems of iran's present financial resources allocation system, one could refer to unclear relations between financial resources allocation policies and economic indicators as well as insufficient attention to the allocations according to projects priorities, absence of a controlled mechanism for allocation aimed for decreasing or eliminating deviations from the plan...

in this research, an integrated inventory problem is formulated for a single-vendor multiple-retailer supply chain that works according to the vendor managed inventory policy. the model is derived based on the economic order quantity in which shortages with penalty costs at the retailers` level is permitted. as predicting customer demand is the most important problem in inventory systems and th...

This paper examines the higher-order moments and nonlinear dynamic properties of discount bond returns in an equilibrium heterogeneous agent economy with incomplete markets and borrowing constraints. We "nd that while it is possible for the economic model to match the mean and variance of the observed bond returns by choosing the parameters such that the borrowing constraint is binding su$cient...

train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. on the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. first, we propose a fuzzy energy ...

in this paper, we develop a capacitated location-covering model considering interval values for demand and service parameters. we also consider flexibility on distance standard for covering demand nodes by the servers. we use the satisfaction degree to represent the constraint of service capacity. the proposed model belongs to the class of mixed integer programming models. our model can be redu...
