Location-allocation problems arise in several contexts, including supply chain and data mining. In its most common interpretation, the basic problem consists of optimally locating facilities and allocating customers to facilities so as to minimize the total cost. The standard approach to solving location-allocation problems is to model alternative location sites and customers as discrete entiti...

Background and objective: The location of facilities is of great importance in healthcare and is of interest to researchers due to its importance. In this regard, a large proportion of classic location-allocation models concentrate on solving problems in an exclusive environment (non-competitive), but this assumption is rarely true in reality. Methods: At...

In this paper, a closed-loop location-inventory problem for spare parts is presented. The proposed supply chain network includes two echelons, namely (1) distribution centers (DCs) and repairing centers (RCs) and (2) operational bases. Multiple spare parts are distributed among operational bases from distribution centers in the forward supply chain and failed spare parts from operational bases ...

The recent trends in electrical power distribution system operation and management are aimed at improving system conditions in order to render good service to the customer. The reforms in distribution sector have given major scope for employment of distributed generation (DG) resources which will boost the system performance. This paper proposes a heuristic technique for allocation of distribut...

Flood management can be defined as the technique and strategy to reduce risk damage from flooding. The efficient strategies for both short-term long-term plans is needed in order minimise losses during disaster happen. governance entails need of a coordinated system dealing with this natural disaster. phases flood cycle such preparedness, mitigation, Emergency Response Plan (ERP), recovery help...

The channel allocation is one of the key problems in the design of the wireless network, as it greatly influences the throughput and performance of the network. Firstly we introduce the channel propagation model, which is able to accurately reflect the signal attenuation, the network interference and other factors in the actual environment. Based on this work, we put forward the channel allocat...

In this paper we address the issue of locating hierarchical facilities in the presence of congestion. Two hierarchical models are presented, where lower level servers attend requests first, and then, some of the served customers are referred to higher level servers. In the first model, the objective is to find the minimum number of servers and their locations that will cover a given region with...

Given a sequence of activities and transport modes, for which a framework has been provided in previous work, this paper evaluates the use of a Reinforcement Machine Learning technique. The technique simulates time and location allocation for these predicted sequences and enables the prediction of a more complete and consistent activity pattern. The main contributions of the paper to the curren...
