IN2SMART 2
Intelligent Innovative Smart Maintenance of Assets by IntegRated Technologies 2.
Goal
The main objective of WP14: Track maintenance decision support tool for a Swedish heavy haul railway line (TRV is the lead) is to develop a decision support tool for railway track maintenance. These objectives can be divided into the following sub-objectives:
- To collect, measure and detect the track status and precursors of track degradation based on work IN2SMART
- To integrate the prediction model of the behaviour of track degradation for segments developed in IN2SMART with predictive models with the possibility to including isolated defects
- To implement and adopt the integrated RAMS, LCC and Risk framework for generating maintenance plans for maintenance schedules, previously developed in IN2SMART
- To define specifications and requirements for an Integrated Maintenance Decision Support Platform and to incorporate the human factor guidelines developed in IN2SMART
The WP is divided into the following subtasks:
- Task 14.1: Monitoring and inspection of track geometry and precursors
- Task 14.2: Diagnostics and Prognostics
- Task 14.3: Decision Support System
- Task 14.4: Demonstrator Development
Projects status and results
The decision support tool aims to employ data-driven methods to develop an integrated platform to support effective track geometry maintenance planning and scheduling. In order to achieve the aim of the decision support tool, different functions and processes must be implemented in the Integrated Maintenance Decision Support Platform (IMDSP). The main parts of the decision support tool are (1) measurement and asset data management, (2) analysis of current and future track geometry condition, (3) maintenance planning and scheduling, and finally (4) demonstration. This will support the process of track geometry maintenance planning and scheduling by providing a picture of the track geometry condition, the maintenance needs, and the available scenarios for maintenance planning and scheduling. Figure 1 shows the basic building blocks of the decision support tool.
Deliverable D14.1 is the first output document of WP14. D14.1 describes specifications and requirements for the decision support tool, data collection and methods of diagnosis, prognosis, planning and scheduling. This includes the inputs, methods, and outputs of track geometry degradation modelling as well as planning and scheduling of maintenance activities. In addition, it provides the readers with the specification and features of the data, which will be used in the development of WP14. It should also be mentioned that this deliverable is linked to the T14.4 “Demonstrator development”.
The main output of the IMDSP is the tamping schedule. Therefore, the demonstrator will provide a graphical view of the optimum tamping schedule with the related information about the KPIs. This will show the users the time and location for performing tamping activities.
