Decision-making concerning thelocation of critical resource on the geographical network is important in many industries.In the healthcare system,these decisions include location of emergency and preventive care. The decisions of location play a crucial role due to determining the travel time between supply and de//////mand points and response time in emergencies.Organs are considered as highly ...

In hierarchical service networks, facilities at di erent levels provide di erent types of service. For example, in health care systems, general centers provide low-level services, such as primary health care, while specialized hospitals provide high-level services. Because of the demand congestion at service networks, the location of servers and their allocation of demand nodes can have a stron...

Background and Objectives: One of the key issues in determining location for blood supply center is the design of blood supply chain. To minimize the cost of blood supply, the donors should be reached easily with appropriate distribution of blood and blood products to the hospital. The aim of this study was calculating of the optimal number and location of different various t...

in this study, a cross-docking system is designed at strategic and tactical levels. for making the strategic decisions, a multi-objective nonlinear location allocation model for cross-docks is presented based on a distri-bution location allocation model by andreas klose and andreas drexl. the model is further developed to in-clude the whole supply chain members and the objective functions are w...

in this paper, a location allocation (la) problem in construction and demolition (c&d;) waste management (wm) is studied. a bi-level model for this problem under a fuzzy random environment is presented where the upper level is the governments who sets up the processing centers, and the lower level are the administrators of different construction projects who control c&d; waste and the after tre...

conclusions according to the results, the iranian public health centers preparedness against disasters before, during and after accidents were in safety level 4 from 10, which was undesirable. results risk rate, functional, non-structural and structural preparedness and final safety level were 58.62%, 51.48%, 54.82%, 33.97%, and 43.72%, respectively. background ahvaz metropolitan as an industri...

majority of models in location literature are based on assumptions such as point demand, absence of competitors, as well as monopoly in location, products, and services. however in real-world applications, these assumptions are not well-matched with reality. in this study, a new mixed integer nonlinear programming model based on weighted goal programming approach is proposed to maximize the cap...

INTRODUCTION Facility location decisions are costly and difficult to change. One of the most important issues in facility location problem and specifically supply chain management is locating and allocating the distribution centers. These strategic decisions are critical factors of whether materials will flow efficiently through the chain network. The location of distribution centers are affect...
