Thesis: MScEng (Industrial) March 2012 Physical Asset Management (PAM) is becoming a greater concern for companies in industry today. The widely accepted British Standards Institutes’ specification optimized management physical assets infrastructure PAS55. According to PAS55, PAM “systematic co-ordinated activities practices through which an organization optimally manages its assets, their associated performance, risks expenditures over life cycle purpose achieving organizational strategic plan”. One key performance area Care Plans (ACP). These plans are maintenance strategies improve or ensure acceptable asset reliability during useful life. Maintenance such as Condition Based (CBM) acts upon Monitoring (CM) data, disregarding previous failure histories asset. Other strategies, Usage (UBM), based on histories, does not consider CM data. models make use both data develop model represents underlying behaviour under study. can be high value ACP development due fact that Residual Useful Life (RUL) estimated and/or long term ii Stellenbosch http://scholar.sun.ac.za
