Output–Input Ratio Efficiency Measures

Part of the International Series in Operations Research & Management Science book series (ISOR, volume 240)


Ever since the industrial revolution, people have been working to use the smallest effort to produce the largest output, so that resources, including human, are utilized more efficiently. Manufacturing companies develop standards to help achieve this, such as the number of items that should be produced with one unit of a certain type of input, in order to better control the production process and increase productivity. Similarly, service companies aim to increase the number of customers served by one employee in a unit of time.
