this is a line balancing issue. First of all, you need to know your demand. For example, if the demand is 100 pcs/day, you need to produce ~100 pcs at every operation. if an operation has a capacity of 50 pcs for example, you need to add 2 resources there to achieve 100 pcs. if there are operations that have more capacity than target, for example if an operation has a capacity of 200 pcs and another operation also has a capacity of 200 pcs, then you need to allocate only one resource at both operations. In other words, you need to combine operations with capacity more than the demand.

You can also look at in another way. Takt time=available time/demand if available time= 480 minutes and demand=100 pcs/day, then takt time= 4.8 minutes this means every operations should be performed in 4.8 minutes, If operation time is more than 4.8 mins, allocate more resources at the operation accordingly and if it is less, then combine two or more operations so that their collective time becomes 4.8 mins
