7. Forecasting
Trend Forecasting
Tell us in which direction (Growth) of
the historical data, and usually is a
long term forecast.
Seasonal Forecasting
Tell us the Seasonal, Cyclic shocks,
we used it to define the forecasting
Pattern
Trend vs Seasonal Forecasting

9. Forecasting
- Measuring the accuracy of forecasting- Model Fairness
- Coefficient of Correlation R
- Tracking Signal T.S.
Two Main factors: (conditions)
R2 > 80%
AND
-4 < T.S.< 4
R2 = Coef. Of Determination T. S. = Tracking Signal

11. Forecasting
- Traffic Forecasting
Selecting the right forecasting technique is the most successful factor,
since the forecasting pattern of airlines are subjected to many
elements, and each route characterized by its growth and seasonality
patterned, in term of seasonality, it is subjected to summer, winter, back
to school, Haj and Umora.

26. Targets
Targets:
Most of the airlines and airports working on
achieving goals, targets, and evaluate their
achievements by comparing the current achieved
results to results of previous week, month, or year
i.e looking backward to analysis current situation.
But for setting targets we have to look forward,
forecast, develop a plan for current situation, to
achieved these targets in future in most efficient
way, so we can compare the current achievement by
the target one, here we can measure our
performance & KPI.

39. Summary
Most of the airlines practice the classical methods, they
evaluate their current performance based on the past results, they just
looking to the back only for one Year ( or same period as month).
While this study explore the effect of historical data in terms
of trends forecast, in which direction the airline business moves, and
the second part is addressing the short term impacts of seasonality
(here months) based on three (3) years monthly data base, keeping in
minds the model fairness constrains i.e (R2) and (T.S.) to minimise the
forecasting errors, then compare the forecasted/planned figures by the
actual one.
The new constrain for this model is to match the accumulated forecasted
months by (Seasonal Model – 3 years data base) with the proposed forecasted year of
Trend analysis (Trend Model – 19 years data base).
Results:
By Planning method the accuracy is high in terms of Standard Deviation i.e 0.037
while the Classical method is 0.092.
