In this paper, we present and apply an approximate hypercube queuing method to analyze an emergency maintenance system within the agricultural stage of Brazil’s sugarcane industry. We incorporate differentiated service rates in the approximate hype

We model and evaluate an emergency service system in which cross-trained fire-medics respond to both fire calls and medical emergencies. Compared to the traditional system, adding the server flexibility may be beneficial in terms of both cost savings

Emergency medical services (EMS) assist different classes of patients according to their medical seriousness. In this study, we extended the well-known hypercube model, based on the theory of spatially distributed queues, to analyze systems with mult

In this paper we propose a cutoff hypercube queuing model to analyze server-to-customer emergency services operating with server reservation. We are motivated by certain SAMU’s (Systeme d’Aide Medicale Urgente) that give assistance to different c

This work extends the hypercube queuing model to address users in-queue priorities.The extended model also considers the partial backup of servers.It is motivated by an emergency maintenance service of an agro-industry in Brazil.To reduce the computa

The aim of this study is to develop a Tabu Search (TS) procedure for the Extended Maximal Availability Location Problem (EMALP). This probabilistic location problem consists of locating the servers of the system so that the expected coverage of deman

In this paper, we study the effects of considering homogeneous versus non-homogeneous servers in applications of the hypercube queueing model. This is important since approximate methods available for solving the model for homogeneous servers are com
