Lean Simulations: “Batch vs One Piece Flow with Transport – Office” Now Available

Here is a screenshot of the latest Lean Simulation.  It demonstrates a significant improvement can result from reducing transport times.  The key is lower travel times between workstations lead to smaller batch sizes.

5-1B Batch with Transport Office

If there is a transport time, one piece flow in this example does not work and documents must be batched together. However, once we reduce transport time, we find the optimal batch size decreases as well. By the time we get transport time to zero, one piece flow is optimal. The results are dramatic:

Here is how the documents spent their time going through the system:

Combining Simulations on Variation in Push Systems

With an eye toward simplifying our own offerings, we are combining the following simulations:

  • Variation in a Push System-Part 1-Office Work
  • Variation in a Push System-Part 2-Office Work

This will now be simply one simulation file called “Variation in a Push System-Office Work”.

Likewise:

  • Variation in a Push System-Part 1-Mfg
  • Variation in a Push System-Part 2-Mfg

This will now be simply one simulation file called “Variation in a Push System-Manufacturing”.

The two different versions were very small models and we felt they could be presented better as one file. The screenshots and documentation have already been updated and the videos will be in the next few days. Lean Six Sigma trainers will now have two fewer simulation files to go through.
