· As an early example, in 1890, Herman Hollerith developed a method for machines to record and store information on punch cards for the US census. Hollerith's machine was approximately ten times faster than manual tabulations and saved the census office millions of dollars. More recent computers could improve these results even further.. automationAdvantages and disadvantages of automation. Advantages commonly attributed to automation include higher production rates and increased productivity, more efficient use of materials, better product quality, improved safety, shorter workweeks for labour, and reduced factory lead output and increased productivity have been two of the biggest reasons in justifying the use of automation.. Advantages and Disadvantages of Automation · Even machinery for which the development cost has already been recovered is expensive in terms of hardware and labor. The cost can be prohibitive for custom production lines where product handling and tooling must be developed. • A skilled maintenance department is often required to service and maintain the automation system in proper working order.
