The 12th: Let's decide the person in charge! (No.2)
~ Waste of transport vs. Waste of waiting ~

Unnecessary transport and waste of waiting often disturb the person in charge who allocates work.
This is due to the interworking of factors such as facility placement and transport time, and direct working time such as processing and assembly and various other factors. It is difficult to decide the optimal allocation easily.

Tech Magazine Practice of GD.findi

Let's try using GD.findi to evaluate which factor is wasteful of transportation and waste of waiting, and which factors will affect productivity, and to decide the assignment of workers to be assigned.

We use the model we introduced last time (The 11th: Examination of the number of facilities and equipment capability ~ Increase facitilies or Increase equipment capacity? ~.

1. Assigning equivalent work to all workers
First of all, let's assume that all workers are responsible for all workers, as shown in the assignment shown in the figure below.

Add one worker (worker 3) to the previous model and set the assignment of transport activity.

Here we will implement rendering and look at production capacity.

The result indicates that it completes at 44 min and 42 sec.
Next, let's change the assignment of work.


2. Make each direct work and transport work dedicated respectively
We try to divide the workers in charge by direct work, here "work: ○ ○ ○" and "transport: ○ ○ ○" which is a carrying operation. The assigned allocation table will be as shown below.
As a prediction, each direct work and transport work dedicated respectively, so there is a possibility that each work efficiency, work quality, proficiency etc. has been improved.

Change the model setting.
The station activity assigns worker 1 and worker 2, and the transport activity assigns worker 3 respectively.

Then, let's see the result.

In this case, the production was completed at 38 min and 40 sec.
It clearly shows that productivity has been improved by clearly separating the responsibilities of direct work and transport work.
Then, how did we get this result?

3. Compare each behaviors
First, while watching the status of floor plan pane at a certain point, in the case where all the workers are equally responsible for equivalent work, all the workers are carrying and even in the condition that direct work can be implemented, worker in charge of it often becomes absent in the place.

While watching the material flow chart, you can grasp that the situation is occurring in every scene.

This indicates that there is a room for improvement in transport rules.
If you do not give any condition to the transport work, it can be said that waste of transport gets bigger.
On the other hand, what if you divide responsibilities for the direct work and the transport work?
Here, by having one person taking charge of conveyance, the other two workers can concentrate on work directly, this layout and line balance does not generate waste of handwork, waste of conveyance is kept as a low-level.

Direct workers start working at other places with minimal movements when it becomes handsfree, thus you can find that there are no cases of the largely accumulated inventory in the material flowchart.

Through this example, it is clear that it is a model with a high ratio of operation of transport worker compared to the direct worker and it is a production system with less waste of waiting, thereby some effects can be obtained by allocating the direct work and the transport work.
In addition, when all workers are to be in charge of the whole work, it is necessary to carry conditions, and it is founded that we can work on the improvement in the waste of transport.
GD.findi also enables you to solve the work decisions made by workers' responsibilities which was mixed such direct work and transport work. Please use it by all means.
