Abstract

Subway stations play a significant role in big cities today. This research aims to develop an integrated system that makes the best use of the budgets allocated for the rehabilitation of Cairo metro stations, based on stations condition assessment. The main problem is the lack of accurate assessment and decision-making optimization tools for Cairo metro stations condition. This, in turn, adversely affects the stations selected for rehabilitation and, thus, the misdirection (non-optimal) of the budgets allocated to the development of these stations. The appropriate methods and techniques of collecting and analyzing data are applied. They were collected from the reviewed literature concerning subway station facility management systems, as well as experts in the field. Data collection was followed by the analytic hierarchical process (AHP) and linear programming/integer programming and ended with the selection of stations prior to restoration or maintenance depending on the available budget or capital program. This system would be helpful in subway stations facilities decision-making by the concerned authorities like NAT (National Authority of Tunnels) or Cairo Metro Co. This system was applied to a sample of Cairo metro stations and concluded with some results. The first of them is reducing and optimizing the great allocated budgets by using the developed model. Another result is that the most important factors influencing the evaluation of the metro station are the structure, architecture, and hydromechanics, respectively.

Highlights

The metro is a huge complex network, combining various disciplines: economy, assets, climate, etc
This section will clarify the research methods used in research to reduce or make the optimal use of the allocated budgets for Cairo metro stations rehabilitation according to stations condition assessment
The Cairo Metro stations were selected to be the case study of the Stations Rehabilitation Assessment Model (SRAM) model application, because of the great area that the Cairo metro framework serves inside the greater Cairo

Summary

Introduction

The metro is a huge complex network, combining various disciplines: economy, assets, climate, etc. The term “Cairo Metro” refers to a rapid transit rail network that serves the urban and suburban areas of the Cairo district. It combines three lines, with more than 70 km of tracks and seventy stations currently in operation, with an average of 3.6 million ridership/day [2]. The significant role of subways in Egypt conforms with a study which argued that countries, the developed nations, have been putting big assets in the improvement of metro networks. The proficiency of metro frameworks has drawn in expanding interest among authorities, experts, and researchers. Multi-Criteria Decision-Making techniques were used clearly in the management of waste [4], choosing ventilation for projects [5], picking the best strategy of restoration and rehabilitation for diverse project components [6], as well as infrastructure project management [7], and materials providers determination [8]
