Military assets are generally appraised at the acquisition stage on the basis of their total life cycle costs. This study provides a theoretical foundation and a parametric cost model for forecasting the life cycle cost for any kind of heavy military equipment. In the model, the asset operating and maintenance (O&M) costs are estimated as a function of its age over its optimal operational life....

Hospitals outsource several activities of the service support in order to focus on the core healthcare production as maintenance service. Recently, faced to the sophistication and the costs of medical equipment that continue to escalate, governments have implemented new reforms to control costs and improve the efficiency and the quality. Hospitals become interested in minimizing the total opera...

We conducted multivariate analyses to examine whether high health maintenance organization (HMO) penetration and large share of for-profit health plans in a market reduced hospital cost and revenue growth rates between 1989 and 1998. We found that hospitals in high HMO areas experienced revenue and cost growth rates that were 21 and 18 percentage points, respectively, below hospitals in low HMO...

The main aim of the study focuses on the optimizing the response of the PID controllers used typically for temperature control loop in centrifugal machines in sugar industry using soft-computing. The centrifugal machines are used for the filtering sugar and molasses and the whole process is carried out at a certain fixed temperature. Any alterations from the set-point will cause instability in ...

Exergy and thermoeconomic analyses are herein employed to evaluate the proposed refrigeration cycle of Tabriz olefin plant. The exergetic and exergoeconomic variables of all equipment and streams are calculated. Thermoeconomic model is developed according to the total revenue requirement (TRR) method. The results indicate that the rational efficiencies of the Heat Exchanger E-104 and compressor...

This study considers the inspection and maintenance of boiler heat exchangers, which are examples a system composed degrading, non-repairable components in series whose operation can be restored by removing failed from service (albeit at performance loss). For such systems, increased failure risk due to component degradation may managed through inspections preventive removal high (again loss fo...
