摘要：Statistical metho ds are nowadays increasingly useful in industrial engineering. Fromplant design reliability to equipment analysis, there is much to cover with statisticalmodels in order to improve the e.ciency of systems. At Sines refinery we found ituseful to apply a Cox model to a particular critical equipment trying to find processvariables that cause its vibration as well as to apply well known distributions tobaseline hazard rate
