this comprehensive work explores the research performed inoptimization of the collection bin and in recycle bin location-allocation issues in solidwaste management. although the collection phase of solid waste management accountsfor a significant proportion of the municipal budget, it has attracted only limitedattention of the researchers. optimization of the collection bin and recycle bin loca...

in the field of health losses resulting from failure to establish the facilities in a suitable location and the required number, beyond the cost and quality of service will result in an increase in mortality and the spread of diseases. so the facility location models have special importance in this area. in this paper, a successively inclusive hierarchical model for location of health centers i...

This paper proposes a discrete capacitated covering location-allocation model for pharmaceutical centers. In the presented model, two objectives are considered; the first one is minimization of costs and the second one try to maximize customer satisfaction by definition of social justice. Social justice in the model means that we consider customers satisfaction by using distance. the introduced...

Recently the concept of facility efficiency, which defined by data envelopment analysis (DEA), introduced as a location modeling objective, that provides facilities location’s effect on their performance in serving demands. By combining the DEA models with the location problem, two types of “efficiencies” are optimized: spatial efficiency which measured by finding the least cost location and al...

background and aims: one of the principles of the quality management systems in organizations is attention to customer centered approach and one of the scales for evaluation of the efficacy of provided services is customer satisfaction. this research aimed to compare satisfaction levels of customers attending primary health care centers in bardsir (with iso certificate) and zarand (without iso ...

Location analysis has so far been limited to spatial, and in some cases spatio-temporal, constraints. For example, the optimal site for a shopping center can be determined by taking the location of other centers and of potential customers into account, and factoring in transportation networks, as well as land use and zoning restrictions. Some solutions, like the relatively unknown but seminal w...

lean thinking is management strategy that is applicable to all organizations including health care organizations, and its main idea is to eliminate waste. finding a suitable location for treatment facilities in the health chain plays an important role in the implementation of this idea in the organization, because on the one hand, proximity to suppliers of medical centers ensures rapid and low-...
