Abstract
Rail systems are gradually becoming the most desirable form of transit infrastructure around the world, partly because they are becoming more environmentally friendly compared with airplanes and automobiles. This paper examines the place of emerging countries in this move of implementing modern rail system that will eventually enhance the realization of a low-carbon society. Network model, transportation model and linear programming algorithms are used to model the present urban rail transport system in Nigeria, as an emerging country, in order to optimize it. Operational research methods, including simplex method and MODI, with the aids of computer software (excel solver and LIP solver) were adopted to solve the resulting models. The results showed that optimization of rail transport system will not only reduce carbon emission but also bring about economic development which is required for the eradication of prevalent poverty in these emerging countries.
Highlights
Emerging countries are developing countries which have achieved individual capacity and are on the path to becoming industrialized countries [1]
The initial tableau was formed from the standardized linear programming model, after which linear programming solver (LIPS) software was adopted to arrive at the following results, with optimum solution equals 25,600,000
The problem was modeled as a linear programming problem, which was solved using simplex method with the aid of computer software— Linear programming solver (LIPS)
Summary
Emerging countries are developing countries which have achieved individual capacity and are on the path to becoming industrialized countries [1]. (2016) Optimization of Urban Rail Transportation in Emerging Countries Using Operational Research Techniques. Application of operational research technique to urban rail transportation projects in these emerging countries will help to maximize value for money and meeting policy objectives. Linear programming and other transporting models are operational research tools used to optimize the urban rail transportation projects of the developing countries in this paper [10]. Linear programming model is a planning technique that uses mathematical model in maximizing or minimizing appropriate measure to optimize the value of some objective after identifying some constraints [10] [11] It may be used for solving broad range of problems in different sectors of an economy including health and transportation sectors [11]. The urban rail transit transportation system, in most of the emerging countries, consists of three parts; the carrying tool, infrastructure and operation management [12]. The railway pattern is still mainly oriented on exporting the resources to other continents, and less on regional trade [13]
