Link and effect model - Link and Effect Model for Maintenance of Railway Infrastructure
Overview
Background & policy context:
Railways are large linear assets of electrical and mechanical subsystems. Consequently the infrastructure managers (IMs) are extensive with many stakeholders involved. The railway infrastructure and the IMs consist of technical and organisational levels: system, subsystem and component levels, and strategic, tactical and operational levels, respectively. Therefore performance measurement systems for rail infrastructure need to integrate both the technical and organisational perspectives, vertically and laterally. It involves several objectives, hundreds of parameters and indicators, data collection, and aggregation of information.
Objectives:
The purpose of the project is to develop a link and effect model for improving performance measurement systems that integrates both the technical and organisational perspectives, vertically and laterally. Therefore, thorough analysis is required for developing an effective performance measurement system.
More specifically, the objectives of this research are:
- To map operation and maintenance activities of railway infrastructure assets
- To develop key values and monitoring methods for RAMS (reliability, availability, maintainability and safety) and LCC (life cycle costing) in maintenance infrastructure contracts
- To develop similar methods and tools for the exchange of key data among stakeholders involved in the railway system, i.e. infrastructure managers, traffic companies, supplier, contractor, etc.
- To develop a link and effect model to measure and monitor changes that affect the operation of the assets
Methodology:
Following steps will be done during the project:
- Literature studies, interviews and real life experiences for process mapping of rail infrastructure
- Factors identification for asset management and its policy as input for the model
- Identification of key performance indicators (KPIs) and key result areas (KRAs) for desired policy modifications and improvements
- Application of the link and effect model for results demonstration and verification as a pilot case study
