The objective of systems enginering is to develop advanced but feasible and cost effective engineering solutions that contribute to enhancing the performance and capabilities of IMS monitoring facilities, and to resolving unexpected engineering problems in the IMS.
Systems Engineering in IMS/ED is considered a work-platform for all other engineering and development activities and includes activities:
- Life-cycle engineering studies (feasibility, cost-benefit).
- Performance modeling
- Failure analysis
- Technical risk management
- Station assessment studies
- Station improvement studies
- Design for station recapitalization/improvement/re-construction
- Equipment testing and validations
- Level 3 O&M support
- Engineering support to LSA and supply chain establishment and management
- Technology awareness/probing/research
At the base of all systems engineering activities and station design is the station functional model, identifying all functions, sub-system specifications and equipment specifications.
ED is responsible for design, develop, implement engineering changes to rectify deficiencies related to data quality, operating cost, obsolescence, reliability, maintainability, etc. In that vein, ED designs, develops and tests hardware and software systems. It also validates station specific design solutions.
ED's strategy is standardization of interfaces and a high degree of system modularity. Open system architecture (OSA) and standardized interfaces allow easy upgrades and swapping of components and reduce susceptibility to obsolescence. (Example: harmonization of Format and Protocols in the IMS (digitizers talking CD1.1) and implementation of a Standard Station Interface.)
Calibration is, by definition, the determination, by measurement or comparison against a standard, of parameters needed to properly interpret recorded signals.
Different initiatives to control such parameters (the system response) of the IMS network are in place.
ED´s responsability is to ensure that the IMS network, as it evolves, maintains compliance with specifications.
Performance management and quality assessment is a vital aspect of ED's work, ensuring that stations comply with its requirements in terms of mission capability, data availability and data quality. It not only ensures that the station's weak points and major contributors to downtime are well identified for focusing engineering efforts where they are needed, but also ensures that this engineering work is done with the highest possible efficiency and quality. While the station risk register, fed from failure analysis and stations assessments, allows ED to plan and prioritize its activities, implementation of engineering processes ensures efficiency of work and quality of products.
