Space product assurance - Worst case analysis

This handbook provides guidelines to perform the worst case analysis. It applies to all electrical and electronic equipment. This worst case analysis (WCA) method can also be applied at subsystem level to justify electrical interface specifications and design margins for equipment. It applies to all project phases where electrical interface requirements are established and circuit design is carried out.
The worst case analysis is generally carried out when designing the circuit. For selected circuitry, worst case analysis (WCA) can be used to validate a conceptual design approach.

Zagotavljanje kakovosti proizvodov v vesoljski tehniki - Analiza najslabšega primera

V tem priročniku so podane smernice za izvedbo analize najslabšega primera. Uporablja se za vso električno in elektronsko opremo. To metodo analize najslabšega primera (WCA) je mogoče uporabiti tudi na ravni podsistema za utemeljevanje specifikacij električnih vmesnikov in mejnih vrednosti pri načrtovanju opreme. Metoda se uporablja za vse faze projekta, v katerih se določijo zahteve za električni vmesnik in izvede načrtovanje vezja.
Analiza najslabšega primera se običajno izvede med načrtovanjem vezja. Za izbrano vezje je mogoče analizo najslabšega primera uporabiti za potrjevanje pristopa konceptualnega načrtovanja.
