The present study was undertaken to measure and compare the relative efficiencies of selected Food Processing Companies in India. relationship between firm performance variables food processing sector has also been studied. Set considered for analysis consisted 20 companies with period covering 8 years from 2005 2012. Efficiency status regressed upon using capital sales ratio, labor cost raw ma...

Relative agronomic efficiency (RAE) of phosphorus (P) in nutrient-rich residues with different chemical characteristics must be known order to optimize their use as fertilizers, avoid underfertilization crops or eutrophication surface waters due overfertilization. In this study, we determined the and RAE manures (cattle, pig, fox) sewage sludges subjected treatments (anaerobic digestion, compos...

data envelope analysis (dea) is an approach to estimate the relative efficiency of decision making units (dmus). several studies were conducted in order to prioritize efficient units and some useful models such as cross-efficiency matrix (cem) were presented.  besides, a number of dea models with interval data have been developed and ranking dmus with such data was solved. however, presenting a...

The aim of this study was to assess the relative efficiency of the Iranian forest management plans using the non-parametric method – Data Envelopment Analysis (DEA) as a well-known and robust technique for measuring the relative efficiency of organizations. The relative efficiency of forest management plans was calculated using the most frequency DEA models such as global technical efficiency (...

this paper concerns the design and analysis, of a ball type continuously variable transmission, (b-cvt). this b-cvt has a simple kinematic structure, and same as a toroidal cvt, transmits power by friction on the contact points between input and output discs, that are connected to each other by balls. after, a brief introduction of our b-cvt structure, the performance and traction efficiency of...
