Calculating man/machine hoursThe man hours and machine hours that are required to carry out an operation are calculated from the data in the Routing module. The most important factors are:
These factors are defined in the following sessions:
Man hours The number of man hours that are required to carry out an operation are calculated as follows: man hours = (setup time * man occupation for setup) + input quantity of operation * cycle time/routing unit * man occupation for production If the operation has a fixed duration, then the man hours are independent of the batch size. The man hours are then calculated as follows: man hours = (setup time * man occupation for setup) + cycle time/routing unit * man occupation for production A fixed duration can be defined in the following sessions:
Machine hours The number of machine hours that are required to carry out an operation are calculated as follows: machine hours = (setup time + input quantity of operation * cycle time/routing unit) * machine occupation If the operation has a fixed duration, then the machine hours are independent of the input quantity of the operation and the routing unit. The machine hours are then calculated as follows: machine hours = (setup time + cycle time/routing unit) * machine occupation A fixed duration can be defined in the following sessions:
