"Typically the demand in flow shops is steady and predictable. This means that the volatility of data is low. On the other hand, the demand in job shops is not as predicable at all but depends on the irregular occurrence of customer orders. So the volatility of data is very high as the environment is very dynamic. " - Flowshop e jobshop
