Background: Estimation of cost functions is an appropriate tool for optimal resource allocation in hospitals. The present study aimed at estimating cost function for hospitals affiliated to Shiraz University of Medical Sciences. Materials & Methods: In the current cross-sectional study, inputs, costs and resources data for 28 hospitals were gathered from h...
Many relational database systems use secondary indexes to reduce the access cost of retrieving data in response to a user’s query. However, a secondary index incurs an additional cost due to the update maintenance of the index. In some cases, this cost may be greater than the cost to update the desired tuples. This paper examines a deferred index update strategy which does an incremental update...
this study examined the relationship between market monitoring cost consist the business disclosure index, the index of perception of corruption, rule of law and regulations quality, and also pointed out the technology index and exercise price limit rules that are in stock. in this research the relationship between the above indicators to price limit rules applied during the period 2005-2010 in...
This paper proposes an optimization model of life cycle cost (LCC) of the transformer. First, to build the model of LCC of the transformer, the whole LCC of the transformer is divided into five costs, i.e., initial cost, operating cost, maintenance cost, fault cost and disposal cost. The whole LCC is calculated. Second, according to the data of several kinds of transformers, the relationship be...
Introduction: Application of inherently safety principle in the early phase of the design process is very efficient, as this approach is an economic and high efficiency method. While a complete information is not available in the initial phases of the process, the use of valid index to evaluate inherently safety can be efficient. In this case, the best route to design safer process can be selec...
