Fault Tree and Reliability Centered Maintenance Training from Isograph

Introduction to NAP (Network Availability Program)

This training course familiarizes attendees with the NAP program. It demonstrates the principles of calculating network availability, and provides an introduction to building a NAP project using Parts Libraries, Block Libraries, and both simple and complex Network diagrams.

Some of the topics covered include:

  • Reliability Block Diagrams. An introduction to the logical structures on which NAP is based.
  • Network Diagrams and Paths. The differences between simple and complex network diagrams, and introducing the idea of paths from source to target nodes.
  • Minimal cut-sets. How NAP calculates the combinations of failures based upon the paths from source to target.
  • Calculating network unavailability and failure frequency. Using boolean algebra, the cut-sets, and the failure rates of individual network components to determine overall reliability for the project as a whole.
  • Parts library. Learning how to store parts data, group parts, and create lists of alternate parts.
  • Block library. How to create commonly used network structures just once.
  • Networks. General usage of the network structure. How to build a network, assign failure rates, and analyze to determine reliability.
