In TQM the role of the employee is very similar to earlier requirements.
If using slack per remaining operations (S/RO) as the scheduling rule, the job with the
least slack per remaining operations has the highest priority.
Backward scheduling develops the LS and LF times.
Project managers use network planning techniques to assign resources to activities.
Slack values for non-binding constraints are equal to 0.
Output/(all inputs used) is called total productivity.
Changing from a multi-line model to a single-line model is most appropriate when the
company is concerned about fairness for its customers.
Removing safety time from the individual activities and putting the total safety time at
the end of the critical path creates a project buffer.
The theoretical minimum number of stations results in the production of daily
requirements when no inefficiency exists.
Facilities decisions are part of the production process infrastructure.
Consider an MPS record. An MPS shipment amount is always set equal to the absolute
value of the amount in the projected available row if that amount is negative.
Typically the job chosen for the time study will be a routine job that is labor intensive.
TQM promotes employees to identify problems and pass onto someone else.
