MAINTENANCE PLANNING OF COLD PLASTIC DEFORMATION TOOLS USING FUZZY LOGIC

For technical systems, generally of high complexity, their open feature may be employed to improve system reliability by preventive renewal. The effectiveness of increasing complex cold plastic deformation tools depends considerably on the characteristics of their maintenance actions and renewal policies are widely used to carry out the preventive renewal. If the derivation of an analytical reliability function is impossible, a fuzzy logic approach for maintenance planning is emphasized in this paper The fuzzy logic decision process for planning the maintenance activities of these tools is presented and a case study illustrates its application. The results of the case study demonstrate that fuzzy logic is a method which can be successfully used in maintenance planning of cold plastic deformation tools.
