The 9th: Examination of worker's allocation
~ Let's decide the worker in charge! Usage of behavioral ND ~

How can each worker share work when a team's area of work is assigned in a manufacturing line?
This time we introduce one way to decide on such allocation.

We consider the following cases this time.
Process: carry-in inspection [20 seconds] (inspection machine) --> intermediate processing [30 seconds] (processing plant 1, processing plant2) --> finishing [15 seconds] (finishing machine)
* The inside of the parenthesis indicates the equipment to be used
Area in charge: intermediate processing, finishing
Team in charge: worker 1, worker 2

Here, both workers can implement intermediate processing and finishing.
Two workers may freely share the work, but when the intermediate machining and finishing places are separated, a loss of movement occurs.
Then, the assignment of work to be done by two persons must be done in consideration of the movement loss, and it is not easy to reconsider the assignment immediately when the layout of the facility changes.

Let's consider this as a function of GD.findi's "Behaviors", so that the movement loss can be minimized.

1. Creating processing and layout
First of all, we create processes and layouts with the above conditions.
Here, processing plant 1, processing plant 2, finishing machines are arranged at a certain distance from each other.

2. Setting team and workers
The team and the responsible setting team will set up the worker master as follows.

Also, in order to have this team in charge of the two work (three work places), double-click the [assignment] part of the station activity and turn on the check box of the team as shown below.

We set this to 3 station activities.

3. Confirmation of production capacity
First of all, let's see the production capacity of just assigning a team.
This time we try rendering with the target number of 100 and the lot size of 10.

By manipulating the cockpit and looking at the situation during production, you can see that each worker is working while repeating the movement to various work places.

4. Control workers' behaviors
If you look closely at the condition of production, the worker moves to another place and performs another work, even though the next work to be processed remains on the spot when the individual work is over. Consequently, one can see that the loss of movement occurs.
This is a status in which there is no control of the operation to the worker, and it also becomes the default operation under this layout, processing time, and worker's assignment.Here, in order to reduce the movement loss, set the worker to do next work in order from the current location.
In order to work from the closest order, set "ND" to the behavior of each task that the team is in charge of.

5. Confirmation of production capacity after motion control
Let's implement rendering with the same target number and lot size as before to confirm production capacity.

As the worker in charge adds motion control to process form the closest order among the tasks to be done, it is understood that the movement loss has decreased and the production capacity has improved as a whole.
When looking at the status under production, worker 1 gives priority to work at workshop 1 from the middle and worker 2 will do the rest. Besides, when the work at the processing plant 1 was completed, it moved to the finishing machine and finished work to do.

From this result, it was found that in this case the production capacity is high by carrying out the following work sharing.
Worker 1: The work place 1 is initially held as a place, and as soon as all the work there is done, we move on to the work at the finisher.
Worker 2: At first, hang the processing place 2 and the finishing machine, and as soon as the hand of the worker 1 is available, it is dedicated to the work of the processing plant 2.

As described above, by incorporating the direction of problem solving such as the reduction of movement loss, this enables to use it very effectively by conducting the verification as a judgment material in making decisions for each worker in the team.
Please use it by all means.
