Facing supply uncertainty of bulky wastes, the capacitated multi-product stochastic network design model for bulky waste recycling is proposed in this paper. The objective of this model is to minimize the first-stage total fixed costs and the expected value of the second-stage variable costs. The possibility of operation costs and transportation costs for bulky waste recycling is considered ...

Kingman Regional Medical Center of Kingman, Ariz., is a 235-bed rural hospital serving a fast-growing community with expanding healthcare needs. Like most hospitals and health systems, Kingman Regional faces the challenge of rising expenses and declining levels of payment. In 2007, the hospital improved its financial performance by correcting widespread procedural and systems issues that were c...

Oil prices, associated with bouts of inflation and economic instability over the last 30 years, have been rising in recent months. We argue that the inflationary consequences of a rise in oil prices depend upon the policy response of the monetary authorities. They can ameliorate the short term impacts on output, but only at the cost of higher inflation. In the short term the size and distributi...

A comparative assessment of market-based climate policy instruments –carbon tax vs. ETS– for emission reduction in the Mexican electricity sector is presented. Model-based scenarios of different tax and cap levels were simulated on an existing Balmorel partial equilibrium model populated with data from the Mexican electricity system. The simulation results served to compare the performance of b...

Recycling information can be complex and often confusing which may subsequently reduce the participations in any waste recycling schemes. As a result, this research explored the roles as well as the importance of a holistic approach in designing recycling information using 15 expert-based (in-depth) interviews. The rationale was to offer a better understanding of what constitutes waste, recycli...

the purpose of this study was to evaluate the profitability of hatchery litter recycling into poultry feedstuff supplement. the data were collected in 2011 in 4 provinces, by direct interviewing of all hatcheries which used the hatchery litter drying machine. net present value (npv), benefit-cost ratio (bcr), and internal rate of return (irr) methods were applied for this analysis. in the studi...
