Airline Schedule Planning
What is the planning sequence for aircraft schedule planning? Firstly, have a business plan which would include competitive strategies and policies which establishes operations and capacity strategy. After that, aggregate plan to estimate your operations capacity and finally produce a master schedule to establish schedule for specific products.
The importance of doing aggregate planning is manifold. It is a fact that it would take time to implement plans because certain period of lead time would exist and this requires and early start to place and order for procurement. Secondly, it is impossible to predict with accuracy the timing and volume of demand for individual items. Also, it would help the flow of supply chain throughout.
Aggregate planning (an overview)
The steps are as follows:
1) Begin with forecast of aggregate demand for the intermediate range
2) The plan will be geared to meet demand requirements by setting outputs, finished goods and employment etc
3) Other alternatives will be developed as well and the best one chosen
Two types of planning is mathmetical and trial error techniques. The steps to do this is as so:
1) Determine demand for each period.
2) Determine the capacities for each period. This are regular time, over time, subcontracting for example.
3) Identify company or dept policies that are pertinent
4) Determine unit costs for regular time, overtime subcontracting
5) Develop alternative plans and compute the cost for each
Production Planning and Control
Activities include:
1) Forecast 2) Planning and 3) Control
Types of checks:
1) Overnight maintenance
2) A Check
pre flight visual inspection (every 2-3 weeks) of fuselage exterior, power plant etc
3) B Check
Every 3-4 month, preventive maintenance such as exterior wash, oil filters are removed and checked
4) C Check
Every 15 months, incorporates both A and B checks. Flight controls repaired and heavy lubrications done.
5) D Check
typically every 6-8 years. Task include cabin interior are removed to enable careful structural inspections
Some airlines conduct what we call an intermediate layover check, where the airline incorporate more than one check into one that is done on a more frequent basis.
