A study on overall line efficiency (OLE) centered production line maintenance prioritization considering equipment operational reliability

Maintenance task prioritization is essential for a production system, especially in the case of limited available resources. In this paper, overall line efficiency (OLE), which comprehensively evaluates productivity and processability, adopted as objective to develop maintenance prioritization. An OLE centred policy proposed, assigns priorities according influences specific characteristics equipment operational reliability on OLE. order correctly allocate resources truly critical achieve good effect, are analysed from level performances their reliability, i.e. mean time between stops (mtbs), resume (mttr) buffer size N. Considering interactions these parameters, surrogate model-extended Fourier amplitude sensitivity test (SM-EFAST) process integrated accurately rapidly analyse total effects them Finally, study has been carried out verify proposed method, higher lower cost were achieved.
