In this manuscript, an attempt has been made to predict and improve the overall equipment effectiveness of core drill rigs. A combined Box–Jenkins artificial neural network model was used develop a three parameter (drill pushing pressure, penetration rate & average pillar pit cycle time) for predicting effectiveness. efficiency The values mean percentage error, root square normalized men bi...

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 (...

Data envelopment analysis (DEA) is used to estimate the overall efficiency and productivity growth of credit cooperatives in Japan during 1992–1996. Overall efficiency is decomposed into output technical efficiency and input allocative efficiency. Twenty percent of all credit cooperatives in Japan are foreign owned with more than 90% of those owned by Koreans. The history of institutional discr...

A new simulation model for Hydrogen production is developed on the Aspen Plus platform. Designing, Analysis and Optimization of the Metal Chloride based cyclic process is done thereby calculating the energy, exergy and overall efficiency of the same using the simulation software. Kinetic and thermodynamic analysis of chemical reactions occurring in each equipment of the proposed model is done. ...
