The total track inspection

Operations of railway business have always placed “safety” as the first priority. Managing “public safety” requires integral risk monitoring and management. The risk monitoring for rail infrastructure management relies on accurate health monitoring and integrated track inspection. Health monitoring of all rail assets have given rise to “Big Data,” which have been derived and recorded from on-board monitoring and on-track inspections of both fixed and mobile assets. In this paper, the safety-critical inspections of fixed assets or railway infrastructures have be emphasized in order to obtain the integral insights into track defects, irregularities and deterioration of track geometry and components. This paper highlights the systems-based integration framework of on-board and on-site inspection data for railway track integrity assurance under uncertain settings. The risks and consequences of extreme climates have been considered in order to improve adaptiveness, agility, and readiness of the systems-based framework of the total track inspection activities that could underpin and assure track infrastructure integrity and resilience. New challenges in observational field data have been highlighted as the evidences for the necessity for the adaptive systems-based framework of the total track inspection

Disruption management of resource schedule in transportation sector : understanding the concept and strategy

Disruption in a schedule (or plan) can be managed but not all factors are visible. A study of disruption management is performed specifically to minimize the differences between the expected and actual context of execution. The purpose of this paper is twofold: first to offer an introduction and deliver a concept of disruption management in the transportation sector. Second, we aim to understand challenges in a rescheduling strategy to manage disruption in the area of resource scheduling. Real world applications from airline to railway services are used as a basis of the investigation. A discussion on the future development of disruption management with a focus on rail track inspection is provided in the final part of this paper
