The intelligent Traffic Management System for Emergency Medical Service Station Location and Allocation of Ambulances

Abstract

In the present study, the optimization of medical services considering the role of intelligent traffic management is of concern. In this regard, a two-objective mathematical model of a medical emergency system is assessed in order to determine the location of emergency stations and determine the required number of ambulances to be allocated to the station. The objective functions are the maximization of covering the emergency demands and minimization of total costs. Moreover, the use of an intelligent traffic management system to speed up the ambulance is addressed. In this regard, the proposed two-objective mathematical model has been formulated, and a robust counterpart formulation under uncertainty is applied. In the proposed method, the values of the objective function increase as the problem becomes wider and, with a slight difference in large dimensions, converge in terms of the solution. The numerical results indicate that, as the problem's complexity increases, the robust optimization method is still effective because, with the increasing complexity of the problem, it can still solve large-scale problems in a reasonable time. Moreover, the difference between the value of the objective function in the proposed method and the presence of uncertainty parameters is very small and, in large dimensions, is quite logical and negligible. The sensitivity analysis shows that, with increasing demand, both the number of ambulances required and the amount of objective function have increased significantly.

A Novel Optimization Approach for Educational Class Scheduling with considering the Students and Teachers’ Preferences

“…In this section, an integer linear programming model is presented. In this regard, the principles of proposing a new mathematical model are inspired by [10][11][12][13][14]. Based on modeling from the subject literature [15][16][17], the objective function of the model is divided into two parts.…”

A New Approach Based on the Learning Effect for Sequence-Dependent Parallel Machine Scheduling Problem under Uncertainty

“…Jobs also decompose at different rates over time, denoted by a factor of α i . To begin processing everything on each machine, we need to spend setup time, which depends on the sequence of the past (see research by [22][23][24][25]). Processing times and delivery times are also fuzzy triangular numbers.…”

The Emergence of a Sustainable and Reliable Supply Chain Paradigm in Supply Chain Network Design

“…In order to optimally design sustainable biofuel supply chains, an economic goal with a total annual cost, an environmental goal with a life cycle of GHG emissions, and a social goal with the number of local jobs have been created have been calculated [193]. In another study aimed at designing and planning supply chain sustainability, the economic dimension according to supply chain costs, the environmental dimension according to Recipe 2008 method, and the social dimension with four indicators introduced by the sustainability guidelines (worker and decent work activities, human rights, society, and product responsibility) has been examined [194]. A general classification of sustainability assessment criteria according to three economic, environmental, and social dimensions is presented in Figure 3.…”
