eKanban Scheduling: Minimal Changeovers vs. Heijunka Ideal

When utilizing the eKanban Planner in the Production Module, you are presented with a variety of scheduling methods to facilitate Level Loading (evenly scheduling production to minimize disruptions). Among these options are 'ONCE PER DAY' and 'ONCE PER SHIFT'. These options are self-explanatory. 

So, let's dig into 'MINIMAL CHANGEOVERS' and 'HEIJUNKA IDEAL'. 

Minimal Changeovers: in a nutshell, utilizing the Minimal Changeovers method allows you to schedule product builds according to the least impactful changeover times between products. 

• Product 1 Changeover time =  60 seconds
• Product 2 Changeover time = 120 seconds 
• Product 3 Changeover time = 240 seconds

*The least impactful changeovers involve the actual time required to perform that changeover. This may be due to product similarity, therefore requiring fewer or faster material or equipment changes. Scheduling is based on time. 

Heijunka Ideal: This method involves scheduling product builds according to Cycle Times, to allow for the most even flow to facilitate level loading. 

• Product A Cycle Time = 10 seconds 
• Product B Cycle Time =  20 seconds 
• Product C Cycle Time =  40 seconds
