The chart displays the monthly production level, the daily production level (monthly divided by 30), and the Takt time for each product type.THEY ARE ALL PRODUCED ON THE SAME LINE.How can these units be built in a level production mode using this example? Model 1Model 2 Model 3Detailed Example Since these three products are on the same line, you will need to follow the sequence pattern of 1213 in your production mix. By doing it this way you are able to levelload your production both in terms of quantity and types. 1 – Prod 1 4 – Prod 3 2 – Prod 2 3 – Prod 1REPEATMixed Assembly LineProduction Sequence by TypeIf produced in batches, only the Model 1’s will meet Takt timesIf produced to a sequence, 2 units will be produced in 2 Takt timesLet’s show how we validate this…ModelLine TaktTakt/Cycle GraphPart QuantityPart Router132 See Std Work Combo Sheet for example.
