What changes when the roster changes?

The problem, as the guideline states it

The ANSP wanted to optimize their rosters in one of their ATC units.

The result, as the guideline states it

The application managed to cover the same traffic demand and accommodated the same number of leave days during a 30-days cycle using 1 less ATCO.

Extrapolating the simulations to other units, the ANSP managed to cut annual costs with the workforces with 8-12% per ATC unit, translating in an economy of 750.000 EUR / year.

The problem, as the guideline states it

An ATC Unit with 96 ATCOs rostered in teams on a fixed shift pattern sees significant variations in terms of overtime distribution per individual staff and increased staff leakage during the night shifts.

The result, as the guideline states it

Compared to the previous simulation, in which 24 additional ATCOs were used to reduce overtime to under 300 hours per month, how is the workload distributed when deploying only the current headcount of 96 ATCOs?

The problem, as the guideline states it

The ANSP is understaffed, scheduling overtime shifts to cover the demand. Due to overtime shifts, staff is overworked, resulting in alarming fatigue scores.

The result, as the guideline states it

The team designed 5 rostering simulations to model their staffing plans in different scenarios.

In the scenario with the best result, the application managed to decrease the number of overtime days from 247 to only 14 during a 35-day roster cycle.

With the new design shift roster and same amount of staff the number of overtime has been reduced but also the number of shifts and consequently the ATCOs have a better fatigue index scores.

The problem, as the guideline states it

The customer was experiencing a high number of shift swap requests - 60.000 per year. For each shift swap request, the planning manager wasted 15 minutes of his time to fill in paper forms and update the roster in a spreadsheet. The customer was paying 5 full-time employees only to manage these shift swaps.

The result, as the guideline states it

By deploying the application inside their environment, the shift swapping process was reduced to 1.5 minutes on average, counting since the manager receives the swap request in the system.

Employees were also empowered to swap their shifts self-service, without involving their manager, the Rostering Engine taking care of the responsibility to maintain a safe, compliant roster with every shift swap approved.

Only by automating the entire shift swapping process, the customer was able to cut costs by 360.000 EUR/year.

The problem, as the guideline states it

An ATC Unit with 96 ATCOs rostered in teams on a fixed shift pattern sees significant variations in terms of overtime distribution per individual staff, and increased staff leakage during the night shifts. This simulation focused to look at difference by adding 24 more ATCOs to arrive at 120 ATCOs in total.

The result, as the guideline states it

How can the roster balance overtime shifts between available employees for a one month period (April 202z) and minimise leakage?
