Wednesday March 5 2014, 11am (Eastern)

Due to the popularity of our recent whitepaper on factoring downtime in to your simulation, we're holding a FREE Webinar on how to factor downtime into your simulation.

Led by Brian Harrington, former Ford Motor Company employee and SIMUL8 expert, Brian is passionate about this subject and is keen to share his knowledge and discuss any questions you may have.

The Webinar will expand on the topics covered in the whitepaper including; questions to consider when working with downtime, capturing at station or line level, associated distributions and accounting for the lockout procedure. In addition, we'll look at simultaneous breakdowns, skill trades to handle your breakdown and more.

Breakdowns Happen: How to Factor Downtime into your Simulation Simulation expert Brian Harrington explains the key learning points simulation modelers should consider when working with downtime.

MTBF & MTTR 1. How often does a machine fail (MTBF)? 2. How long does it take to repair it (MTTR)? These two questions may seem simple, however are often abstracted within the forest of machinery and clouded by human behavior. SIMUL8 Corporation | SIMUL8.com | info@SIMUL8.com

One of the most debatable pieces of data that goes into a simulation is the stochastic behavior of machine downtime. • • • • • • • • • • • Introducing new equipment Collecting downtime data Summarizing downtime data Catastrophic downtimes Lock-out procedures Time to react, travel, and repair Distributions to represent downtimes Limited skilled trades Simultaneous faults Protective capacity Equations (MTBF, MTTF, MTBC, MTTR, etc…) Plants perspective Designer’s perspective SIMUL8 Corporation | SIMUL8.com | info@SIMUL8.com

Advantages of Aggregate Values • Used for predicting station/cell level downtime based on components • Reduces large data files • Ease of communicating downtime figures • Aligned with scope of model SIMUL8 Corporation | SIMUL8.com | info@SIMUL8.com

Time to React & Travel? Named Distributions and the Combination Distribution can capture some of this behavior. SIMUL8 Corporation | SIMUL8.com | info@SIMUL8.com

Lock-out Procedure A safety protocol which protects skilled trades when entering a station or work cell. Each skilled trade will have a named-lock, which will be “locked” on an electrical panel before entering a work cell for a repair. The protocol will have several required steps to assure that all power is off, assuring no machinery, robot, etc. movement. A typical lock-out procedure might take 3 to 7 minutes to complete! SIMUL8 Corporation | SIMUL8.com | info@SIMUL8.com

How do we account for the Lockout Procedure? A lockout procedure might be assumed to be followed on the lengthier repairs such as repair times that take 10 minutes or more. SIMUL8 Corporation | SIMUL8.com | info@SIMUL8.com
