Flyps interpretation of LCC

Within Flyps a simple model of the life cycle cost for a pump station can be made. The "cost model" that Flyps supports is divided in three different parts:
- Investment costs
- Energy costs
- Maintenance costs

Besides the pump cost, the investment costs could be for:
- Excavation
- Civil work
- Mechanical equipment
- Electrical equipment
- Superstructure

The other two cost types, "energy" and "maintenance" costs can be considered as running costs compared to the initial investment cost. The running costs do not only appear initially but also continue throughout the whole life of the pump station. The problem with this is that the value of a certain amount of money changes (decreases) over time.

However, in order to calculate the life cycle cost for a pump station, it is necessary to sum the running costs with the investment cost. To handle this Flyps uses a calculation method based on the net present value principle that takes care of the reduction of the value of the running costs.

In Flyps the energy cost is automatically calculated based on the energy consumption for the selected pump(s). The maintenance together with the initial costs (including pumps) have to be entered manually buy the user.
