Create a Reliability Block Diagram (RBD) or Fault Tree to represent the system logic. Use Weibull analysis to characterize failure and repair data from your ERP/CMMS. Use simulation to model system performance and optimize spare holdings.
Simulate the effects of design and operational changes.
Of course CAPEX will effect OPEX, or it should…or will it? The idea makes sense, however, at what point will a piece of equipment cost you more to maintain than it would cost to simply replace that piece of equipment? Should a refurbish be considered? How should a new plant be configured for the highest cost benefit? Not properly designing a system or not being willing to spend the money to replace equipment at the right interval could be costing you. By modelling your system in easy to use tools you can make logical decisions as well as justifying these decisions.
Although we post a lot of web demos that cover analytical topics related to the Reliability Workbench let’s remember that the Availability Workbench is probably the most powerful tool of its kind on the market. There is a good chance someone you know is using the Availability Workbench!
Availability Workbench is used to optimise maintenance and spares policies, predict system availability and throughput and estimate life cycle costs. It includes well known modelling methods such as FMECA, Reliability Block Diagram Analysis and Fault Tree Analysis.
The following web demo is a high level overview of the software, if you have any questions or need more information on the software please let me know:
