Document Summary
About 10% of their flights are disrupted per year, half because of weather. Cost is millions of dollars in lost revenue, overtime pay, food, and lodging vouchers. The operations control centre at pearson adjusts to changes, notifies passengers, and keeps flights flowing. Short term scheduling: translate capacity decisions, aggregate planning, and master schedules into job sequences and specific assignments of personnel, materials, and machinery. Schedule is produced by working backwards through the processes. Resources may not be available to accomplish the schedule. Often these resources are combined to develop a trade off between a feasible schedule and customer due dates. Process focused facilities: forward looking schedules, mrp due dates, finite capacity scheduling. Work cells: forward looking, mrp, detailed schedule using work cell priority. Repetitive: forward looking, balanced line, pull techniques for scheduling. Product focused: forward looking schedule with stable demand and fixed capacity, capacity, set up, and run times, are known.
