In quality control charts, the problem of determining the optimum process mean arises when the deviation of a quality characteristic in one direction is more harmful than in the opposite direction. The failure mode in these two directions is usually different. A great majority of researches in this area have considered asymmet-ric cost function for processes with single quality characteristics....

BACKGROUND How case volume and quality of care relate to hospital costs or length of stay (LOS) are important questions as we seek to improve the value of health care. METHODS We conducted an observational study of patients 18 years or older who underwent coronary artery bypass grafting surgery in a network of US hospitals. Case volumes were estimated using our data set. Quality was assessed ...

The primary objective of this paper is to find out whether we can use the quality cost model as a tool for visualizing targets in management using costs. analysis showed that graphic interpretation costs companies makes “more visible” and representative”. visualization focuses efforts purposes visibility, monitoring, comparison with at company level, beyond during negotiations.

BACKGROUND According to international guidelines, the goal of asthma management is to achieve and maintain control of the disease, which can be assessed using composite measures.

proposing a robust designed facility location is one of the most effective ways to hedge against unexpected disruptions and failures in a transportation network system. this paper considers the combined facility location/network design problem with regard to transportation link disruptions and develops a mixed integer linear programming formulation to model it. with respect to the probability o...
