The Data Format
Cost and revenue calculations are made from items and rules that you enter. You must first decide on what factors you will base a schedule's cost or revenue, and then determine how OASIS should calculate it (by block hour, by time period, by departure, etc.)
For each factor that you enter, you then must enter the data that applies to it. For example, assume you entered the expense of the cockpit crew as a cost, and indicated that it was based on block hours. Now you must enter the cockpit crew cost per hour for each equipment type in the schedule. Or you may just enter one cost for all your equipment types if that approximation will work.
Cost factors are relatively easy to enter and compute. Adding or deleting a flight usually produces a straightforward change to the cost totals. Adding a flight, for example, will increase fuel usage, pilot and cabin pay, landing fees, some terminal expenses, etc. However, the effect on costs will be still be an approximation. For example, some schedule changes will have an effect on pilot pay that only a crew planning system can truly calculate.
Revenue changes due to a schedule change are much harder to calculate accurately. Adding another frequency between a city pair will add revenue passengers on the new frequency, but remove some from other frequencies. OASIS also does not attempt to calculate how many passengers will be added or lost due to new or deleted flights.
Two reports are produced. The cost report shows the costs for each cost factor you entered, by month for up to twelve months.
The profit report condenses costs to a single line item. It then applies the revenue calculations to display passenger and cargo revenue, profit, yield, and unit cost.
