introduction: hospitals as important sector of health care system has special location in health economic science. increasing of the operational costs in hospital and limitation in financing cause that hospital as an economic firm use cost analysis and prepare effective using of resource and boost productivity. therefore this study was conducted to calculate daily- patient hotel cost in hospita...

This article develops an econometric analysis of metro station operating cost to identify factors that create variation in cost efficiency. Stations operating costs can be classified amongst the semifixed costs that a metro faces in the sense that they do not vary proportionately with metro output. They may therefore be important in determining the degree of returns to density. This article see...

The potential benefits of optimal service scheduling for cleaning heat exchangers based on minimizing operating costs are explored. A demonstration is performed on a simulated 20 ton air-to-air vapor compression air conditioner. The costs of regular service schedules (indicative of current practice), minimal schedules needed to maintain comfort, and the optimal schedules are compared. Generally...

Effective parameters that can effect on the performance of the separation system consist of operating pressure, operating temperature, reflux ratio, and kind of produce desirable products and different sequences of splits. As take a separation system with optimal performance is dependent on optimization of above mentioned effective parameters. In generally, there are two criteria (as object fun...
