Health service management plays a crucial role in human life. Blood related operations are considered as one of the important components of the health services. This paper presents a bi-objective mixed integer linear programming model for dynamic location-allocation of blood facilities that integrates strategic and tactical decisions. Due to the epistemic uncertain nature of ...

Here, we consider single vendor-buyer model with multi-product and multi-customer and multi-facility location-production-distribution problem. It is assumed that the players of the supply chain are coordinated by sharing information. Vendor manufactures produce different products at different plants with limited capacities and then distribute the products to the consumers according to determini...

We study a strategic model in which a defender must allocate defensive resources to a collection of locations and an attacker must choose a location to attack. In equilibrium, the defender sometimes optimally leaves a location undefended and sometimes prefers a higher vulnerability at a particular location even if a lower risk could be achieved at zero cost. The defender prefers to allocate res...

The task allocation problem with pickup and delivery is an extension of the widely studied multi-robot task allocation (MRTA) problem which, in general, considers each task as a single location to visit. Within the robotics domain distributed auctions are a popular method for task allocation [4]. In this work, we consider a team of autonomous mobile robots making deliveries in an officelike env...

Facility location allocation problem is a very important issue in today's global logistic management. Various facility location problems have been considered in operations research under somehow stringent conditions to reduce the search space. In this paper, we consider a class of single source capacitated facility location allocation problems that can assume more realistic conditions in real l...

This paper presents a hybrid algorithm that combines a metaheuristic and an exact method to solve the Probabilistic Maximal Covering Location-Allocation Problem. A linear programming formulation for the problem presents variables that can be partitioned into location and allocation decisions. This model is solved to optimality for small and medium-size instances. To tackle larger instances, a f...

In emergency medical facilities location, the hierarchical diagnosis and treatment system plays an obvious role in rational allocation of resources improving use efficiency resources. However, few studies have investigated operational mechanism systems uncertain environments. To address this research gap, paper proposes a hybrid approach for facilities’ location-allocation. first stage, order t...

The capacity analysis of CDMA forward link is required to allocate high data-rate users. To solve this problem, we analyze the capacity of the CDMA forward link based on optimum power control. In a multi-cell environment, the intracell interference and intercell interference are derived. To show the capacity impact of high data-rate users, we introduce a location dependent factor, which is the ...
