We consider a trader who wants to direct his portfolio towards a set of acceptable wealths given by a convex risk measure. We propose a black-box algorithm, whose inputs are the joint law of stock prices and the convex risk measure, and whose outputs are the numerical values of initial capital requirement and the functional form of a trading strategy to achieve acceptability. We also prove opti...

An experiment was performed to investigate the energy efficiency and effect of poultry house size on energy productivity in 3 different capacity management systems. Capacities of houses were 10000(3 housings), 20000 (2 housings) and 28000 (1 housing) birds per production period and were assigned as HI, HII and HIII respectively. This experiment was conducted in a completely randomized design ap...
This paper aims at estimating the efficiency of hydroelectric power plants (renewable energy resources) and thermal power plant (non-renewable energy resources) in Iranian provinces. Data Envelopment Analysis (DEA) approaches is applied to estimate the efficiency. The network is modeled as a linear system with multiple inputs and one output. Fuel cost, labor force, operation cost are used as in...
