Traditional poultry production has changed to a considerable industry after few decades. Now, poultry industry is one of the main sectors to obtain the required protein for human consumption. Prediction of the weight and number of eggs according to economic traits can improve the efficiency of production and the profit of producers. In present study, the weight and number of eggs in Mazandaran ...

Supply chain network design in perishable product has become a challenging task due to its short life time, spoilage of product in degradation nature and stochastic market demand. This paper focused on designing and optimizing model for perishable product in stochastic demand, which comprises multiple levels from producer, local collector, wholesaler and retailers. The ultimate goal is to optim...

In this paper, a stochastic programming approach is applied to the airline network revenue management problem. The airline network with the arc capacitated single hub location problem based on complete–star p-hub network is considered. We try to maximize the profit of the transportation company by choosing the best hub locations and network topology, applying revenue management techniques to al...

This study examines the cost and profit efficiency of banking sectors in twelve transition economies of Central and Eastern Europe (CEE) over the period 1993-2000, using the stochastic frontier approach (SFA) and the distribution free approach (DFA). The managerial inefficiencies in CEE banking markets were found to be significant, with average cost efficiency level for 12 countries of 72 and 7...

In wireless network convergence, eachmobile host is expected to havemultiple kinds of wireless interfaces.Multicast-based applications are expected to be widely deployed. In this paper, a new network selection scheme is proposed for a mobile host to select the most appropriate wireless access network to maximize user satisfaction and ISP’s profit, simultaneously. We have devised a metric to mea...

This paper theoretically studies the consequences of heterogeneity on self-governance, cooperation, and trust in large communities. I consider a game model where players belong to a large population and are randomly matched. Players interact with each other infrequently and, when matched, play a prisoners’ dilemma. There exists an institution that can convey information on play histories. Playe...

We study an ascending auction of an indivisible good in which agents observe multidimensional Gaussian signals about their valuation of the good. The equilibrium is solved using a two-step procedure. The first step is to project the signals into a one-dimensional equilibrium statistic. The second step is to solve for the equilibrium as if agents observed only the equilibrium statistic (and henc...

Importance of Feed Efficiency The ability to improve the utilization of nutrients has tremendous potential to improve profitability. It has been estimated that a 10% improvement in performance (gain) would increase profit by 18%, while a 10% improvement in efficiency could improve profit by upwards of 43%. It has also been estimated that a 10% improvement in feed efficiency (assumed to be a 2 l...

content discovery is one of the fundamental issues that determines the architecture and performance of content distribution networks based on peer-to-peer (p2p) networks. to administrate the costs and discoveries, peers of a p2p network communicate with each other by one or more overlay layers. the condition of node’s relations in overlay networks, have a great impact in efficiency of networks....
