Tilstandsanalyser

Tilstandsanalyser refer to systematic analyses of the current condition of a system, asset, process, or organization to support decision-making, planning, and risk management. The term is widely used in Scandinavian languages and is analogous to condition assessment or state analysis in English. Tilstandsanalyser are applied across industries, including manufacturing, energy, construction, transportation, healthcare, and information technology.

The primary goal is to determine the present state, identify deviations from expected performance, and assess remaining useful life or risk exposure. Typical steps include defining the scope, collecting data on performance, condition indicators, and inspections; evaluating data through qualitative reviews and quantitative models; identifying gaps and risks; and formulating recommended actions. Outputs commonly include a status report, prioritised action plan, maintenance recommendations, and a risk register.

Methods used in tilstandsanalyser range from traditional inspections and handbooks to modern condition monitoring, statistical analysis, machine learning, and life-cycle assessment. Data sources can be sensor data, maintenance records, operator input, and design specifications. The analyses support maintenance planning, asset management, safety assurance, and investment decisions, by translating observed condition into expected performance and risk.

Limitations include data quality and availability, uncertainty in forecasts, and the need for domain expertise. The quality of a tilstandsanalyse hinges on clear scope, robust data governance, and appropriate analytical methods. See also condition monitoring, asset management, FMEA, and risk assessment.
