Mongo e automatização - tanta treta que se ouve

O meu parceiro das conversas oxigenadoras mandou-me este artigo, "Can There Be Too Much Automation?":
"Much of what you hear about automation focuses on the increased productivity that automation can bring to production lines. You hear about this a lot because it’s a true, measurable reality.
.
But is it possible that too much reliance on automation can hinder the overall productivity of a factory? [Moi ici: Um velho tema deste blogue, Mongo e automatização não jogam bem!!! Ver Lista de artigos abaixo]
...
At Mitsubishi Electric´s Kani manufacturing facility, which is part of the company’s Nagoya Works in Japan, the company found that, by bringing humans into work cells that were once 100 percent automated, the footprint occupied by the cell itself could be reduced by 84 percent.
...
In addition, Mitsubishi Electric notes that the introduction of human workers to previously automated assembly lines is helping the Kani factory react faster to changes in product demand.[Moi ici: Tão Mongo!!!]
...
The Kani factory produces motor starters and contactors for Mitsubishi Electric. The vast amount of production variations and possible configurations of these products—14,000—diluted the volumes of each particular product. This amount of variability, coupled with customer demands for even greater choice, highlighted the automation problem for Mitsubishi Electric. [Moi ici: Tão Mongo!!!]
.
According to the company, manual production at the Kani factory had given way to totally automated assembly lines, which were ideal for mass production with few product variations where high yields could be realized at high speed. But this required many individual components to be held in stock and ready for the manufacturing process; otherwise, the lines would not be able to run for any appreciable length of time.
.
In effect, it became difficult and uneconomical for the factory to produce its products in small batches—which just happens to be the very direction in which industry as whole is headed.
...
The company realized that, by restoring some human elements, it could reduce some of the manufacturing problems it was encountering.
...
Despite that fact that the new cells, featuring a combination of human workers and automation, cannot produce at the same volume and speed as the fully automated lines, the reduced size of the new cells means the company can deploy up to 6.3 cells in the same space once occupied by one cell. Mitsubishi Electric says this means that total productivity density for the facility is much higher due to three key factors: a wider variety of products can be manufactured in smaller batches; one stoppage does not halt the whole of production; and the total number of production lines has increased."
Como escrevo no postal de Fevereiro de 2018 na lista abaixo:
"Muitas vezes penso que as pessoas quando planeiam o futuro não fazem como Teseu no labirinto, não usam uma corda para unir o hoje com o futuro desejado. Por isso, usam lugares comuns. Por isso, não põem os pés no chão e testam a validade dos pressupostos que estão a assumir."
