Abstract: Considering at the deficiency of quantifying the brittleness of manufacturing equipment,a brittle quantitative assessment method of equipment based on performance parameters and brittle risk entropy principle was presented.Through establishing the mapping relationship between the performance parameters and the equipment performance status,the various working performance states of the equipment were divided,and the probability of equipment state was calculated.From the two aspects of the state probability distribution and its impact on the equipment itself,the brittle risk entropy measurement model of the equipment was constructed,and the brittleness evaluation of equipment during the operation was completed.A critical workstation of an engine flexible assembly line was taken as an example to illustrate the effectiveness of the model and method in evaluating the brittleness of the equipment.

Key words: brittleness, brittle risk entropy, manufacturing equipment, performance parameters, engine flexible assembly line
