• A location-allocation problem under uncertainty is investigated. two-stage stochastic programming model proposed. The mode solved by sample average approximation. Emergencies, especially those considered routine (i.e., occurring on a daily basis), pose great threats to health, life, and property. Immediate response treatment can greatly mitigate these threats. This research conducted optimize...

Recent reports suggest the need for further study of the impact of organizational characteristics on quality-related activities in health centers. To better understand these issues, a cross-sectional assessment of quality-related activities in Health Resources and Services Administration-funded health centers was conducted using a mailed questionnaire. Associations between the extent and freque...

The main purpose of this paper is to present a fuzzy multi-criteria decision making (FMADM) model for appropriate location selection of a health center. Therefore, we identify sixteen criteria and sub-criteria for selecting a health center location. These criteria and sub-criteria have been obtained from literature reviews and practical interviews. This paper proposes a method which combines th...

The distribution network design problem for an automobile company in China is investigated. Through optimizing the location of the distribution centers and allocation of retailers to distribution centers or plants, the total profit for the automobile company is maximized. The demand is assumed to be sensitive to the lead time and a Linear Integer Programming model is proposed to formulate the p...

In this paper the questions of defining the optimum allocation of centers in fuzzy transportation networks are observed by the minimax criterion. It is supposed that the information received from the geographical information system is presented as a fuzzy graph. In this case the task of defining optimum allocation of the centers transforms into the task of defining the fuzzy set of graph bases....
