What is Real IE (Industrial Engineering)?
http://www.mejapan.com/09_29.html
I liked this passage in the above post
(2) The optimal combination is the lowest cost
As described above, the IE is a science dealing with the design, improvement, and implementation of a system integrating all production factors. However, the IE has been developed from the science of human beings, and the analysis of "human" in the production factor is the IE method, the analysis of equipment is the TPM (Total Production Management) method, the "material" There is a misunderstanding that the analysis targeting uses the TPS (Toyota Production System) method. (I would say IE is first engineering. It is practice of engineering with focus on productivity right from its birth. TPM has more focus on equipment and it is extension of IE with special focus on equipment. TPS is primarily IE with focus on material that is inventory that is delay reduction.)
However, an optimal production system cannot be obtained even if only the efficiency of one production factor is pursued. *The aim of improving the efficiency of one production factor is contrary to the intent of the IE (Additional explanation: IE is for reducing the total cost of the product being produced or service rendered. So one should not increase the productivity of one factor and increase the cost of another factor much more such that total cost increases).
Some factories are running state-of-the-art capital investment for the purpose of automation, but the decision to replace equipment with humans is whether there is a cost merit. Again, the combination changes between high and low paying countries. On the other hand, it is meaningless to reduce labor productivity by increasing the number of people in the equipment to improve the equipment productivity.
If there are no shortages, it is desirable to have a small inventory, but it is meaningless to aim for zero inventory and increase setup and reduce labor productivity. It is meaningless if the production volume fluctuates due to lack of inventory, resulting in excessive capital investment. You can compare the advantage of inventory and equipment adjustment with money.
As described above, the determination as to whether or not the optimal combination of production factors is made is made with money (cost). Therefore, cost calculation is indispensable for IE.
In Original (Japanese)
最適組み合わせとは最もコストが安いこと
このように、ＩＥはすべての生産要素を総合したシステムの設計、改善、および実施に関することを扱う科学である。しかし、ＩＥは人の科学から発展した経緯もあって、生産要素の中で「人」を対象にした分析はＩＥ手法、設備を対象にした分析はＴＰＭ(Total Production Management)手法、「資材」を対象にした分析はＴＰＳ(Toyota Production System)手法を用いるかのような誤解がある。ところが、ひとつの生産要素の効率だけを追求しても最適生産システムは得られない。ひとつの生産要素の効率化をねらうやり方はＩＥの趣旨に反するのだ。
自動化することが目的のように最新鋭の設備投資に走る工場があるが、人から設備に置き換える判断はコストメリットがあるかどうかである。これも、賃金の高い国と安い国では組み合わせが変わる。反対に、設備に多くの人を配置して設備生産性を向上させても労働生産性が低下しては意味がない。
欠品がなければ在庫は少ない方が望ましいが、在庫ゼロをねらって段取りが増え労働生産性が低下しては意味がない。在庫がないために生産量が振れ過大設備投資となっては意味がない。在庫と設備調整のどちらが有利かもお金で比較してみればよい。
このように、生産要素の最適組み合わせであるか否かの判断はお金（コスト）で行う。したがってＩＥにはコスト計算が欠かせないのだ。

Toyota style Industrial Engineering - Waste Elimination - Ohno
"We have eliminated waste by examining available resources, rearranging machines, improving machining processes, installing autonomous systems, improving tools, analyzing transportation methods and optimizing the materials at hand for manufacturing. High production efficiency has also been maintained by preventing the recurrence of defective products, operational mistakes, and accidents, and by incorporating workers' ideas." Taiichi Ohno (P. 21)

Today I interacted with a Japanese blogger and informed that I have a blog post on IE in Japanese. I updated the post also with good information. I need to read that Japanese blog more.
