Abstract :
This paper describes a method using production levels and gracefully degradable manufacturing systems. A production level is a way of grouping certain activities in a manufacturing system. The method, based on graceful degradation, makes use of the production levels to uphold the availability of the system during computer failures or data network failures. The method is demonstrated on a case study of a machining cell
