The reason we put buffers into a system is to protect the constraint from the malfunctions of other machines.The last thing we want to do is to add downtime to the system caused by the buffers. That would defeat their whole purpose and render them useless. Buffers should be extremely simple in design principle.The simpler they are, the more...

After the constraint has been chosen, or identified, the next step is to protect it. But, protect it from what? What you must protect the constraint from is the effect of malfunctions on machines that are non-constraints. You see, in a close-coupled system, anytime a non-constraint shuts down it immediately shuts down the constraint. This is...

Finding the constraint is simple once the preliminary data previously discussed has been analyzed.You simply look for that operation which has the lowest net output. That net output is now going to be the lines potential thruput. 100% thruput will be whatever the constraint’s net output is.At this point, we have developed a target for the line.You...

It is really simple. If you know:The maximum RATE of the machineThe average length of time a machine is down (MTR)How many times per hour or shift it goes down (MTBF)You have everything you need! Remember, it does not need to be exact.There are checks built into the system that will verify if the numbers are way off, and you only need estimates....

The analysis of the line is a fairly simple process, which will do the following:Identify the constraintIdentify strategic buffer locationsIdentify the optimum capacity for the buffersVerify that there is sufficient rate capacity of the non-constraintsPredict the effect on overall thruputDetermine efficiency thresholds for each machineThe...
