Intro to BlockSim

ReliaSoft BlockSim by HBM Prenscia provides a comprehensive platform for system reliability, availability, maintainability and related analyses. Using exact computations or discrete event simulation, BlockSim facilitates a wide variety of analyses for both repairable and non-repairable systems that are useful to both product designers and asset managers. This includes reliability analysis, maintainability analysis, availability analysis, reliability optimization, throughput calculation, process flow diagrams, resource allocation, life cycle cost estimation and other system analyses. Additionally, BlockSim's event analysis flowcharts (formerly RENO flowcharts) offer capabilities for building and running complex analyses for any probabilistic or deterministic scenario using an intuitive flowchart modeling approach and simulation. The features that are available on your computer will depend on your license.

BlockSim is part of the suite of ReliaSoft desktop applications, which offers intelligent integration between reliability program activities and tools, while simultaneously facilitating effective information sharing and cooperation between engineering teams of any size. For information about features that are shared by all (or most) of the ReliaSoft desktop applications, see the Databases and Projects, Desktop Application Interfaces and ReliaSoft Common Tools chapters.

Other ReliaSoft software by HBM Prenscia includes: Weibull++, Lambda Predict, XFMEA, RCM++, MPC, SEP web portal and XFRACAS.
