Evaluating Systems using RAM Modelling Techniques


RAM studies are used to quantify system performance based on reliability, availability, and throughput. The results provide a measure of design performance or operational performance.
Additional analysis can provide criticality metrics based on system and block failures and downtime allows management to focus on the areas when greatest benefit can be achieved.
RAM Models are typically conducted as part of the design process for new projects. They are conducted to verify that the design will deliver the functional specification. They are usually conducted at a high level using generic data.
RAM Modelling represents a valuable improvement technique during the operational phase using the company's failure and repair data for: Evaluating proposed modifications, repair or replace options Evaluating different maintenance strategies Evaluating optimum tank sizes Evaluating stocking policies for high value critical spares with long lead times. This 2-day workshop shows how to carry out RAM studies and includes the principles of building the model and a step by step approach to conducting a RAM study

What you will learn

As a result of attending this workshop delegates will learn:

  • The importance of reliability and the basic principles of data types
  • How to produce better CMMS feedback reports
  • How to develop failure coding systems

Discussion of delegates' current issues
Common issues encountered by the instructor including CMMS set up, and poor use of the CMMS functionality
Costs of unreliability and risks

Topic 2 How to Improve Work Order Feed Back Reporting
We will look at examples of poor quality data collection and present a structured feedback reporting process and stress the importance of clear definitions to ensure consistent determination of KPIs
