In the last time of issue (Let's make an intermediate inventory model! Create an inventory quantity model), we introduced a method to eliminate the waiting for post-process using GD.findi's initial inventory.
Also, of course, we were able to confirm that the quantity of intermediate inventory became increase.
In this time of issue, we find the answer regarding the question that "how much initial inventory is needed" in order to make full use of post-process, in other words, the question would be "whether the quantity of intermediate inventory has not increased too much" against the capability differences between processes.
Using the GD.findi model created in the previous issue of Tech Magazine, we check the intermediate inventory quantity.
Please refer to the last issue of Tech Magazine as below.
The 3th: Let's make an intermediate inventory model!
(1) Open model and Execute rendering
After accessing and logging into GD.findi, open the previous model and execute rendering with the open model.
* When you first implement rendering in the new window, click the [Reactor start-up] button first and display the [Reactor] tab.
(2) Confirm the transition of intermediate inventory quantity
Let's see the transition of inventory quantity of intermediate stock area by each part.
* Transition data of inventory is generated from GD.findi log file.
Horizontal axis: time, Vertical axis: the number of inventory
Again, implementation of rendering --> generation of inventory transition data from log data Let's check the transition of inventory by doing this.
Then, now let's set the initial inventory of part A as half of "10".
It is obvious that when you see the operating status in the material flow chart.
(4) Determination of necessary initial inventory
(5) Determination of necessary initial inventory of whole parts
From the fact above,
Part A and C are 15, part B is 8, and part D is 22
If these numbers are arranged in initial inventory of stock, it is founded that the remaining number of intermediate inventory at the end of production also does not occur, even also the waiting for the post process.
From 2nd and 3rd time of issues, we have introduced the process of determining the intermediate inventory quantity.
Since the model introduced this time has a simple production system, it may be obtained by a simple calculation, but even for more complicated models, it is possible to prevent the occurrence of waiting for the post-process by observing the changes of inventory as did this time.
Moreover, from next time, we will introduce to you how to use GD.findi for another issues.
