Operation Split

There are two methods on how to split the operations. One of them is to register the lot size for the equipment. In this sample, input 200 as the Resource split size MAX in the equipment Cutter 1.

This method is used when the quantities, which can be processed, are different for each piece of equipment. Run the reschedule button and you will see that the operations have been split.

During the assignment of operations, which were split as mentioned above, the corresponding instructions can be assigned separately.

Furthermore, it is also possible to shorten the lead time, by setting the Time constraint method as “ESE”.

Run the reschedule button and you will see that the operation has been finished earlier than the previous sample.

Another method of operations splitting is to register the Production lot size MAX for each item at the [Item table].

Asprova5

When the production quantity is larger than the lot size of the item, the operations will be split and then assigned.

Asprova6

This is used when the production quantities are different for each item.

Also, when there are several pieces of equipment, parallel production becomes possible and can reduce lead time. This can be done by changing the Time constraint method to “SSEEE”.

Note also that the operation split function has plenty of effects, such as split by rate, switching workers by shift, etc.
