Case Study

Fictitious Company
“Pumps Inc.”

Initial Situation

Pumps Inc. is an internationally active company in the industrial goods industry. The company generates the majority of its annual turnover of €2.4 billion with the sale of pump systems for various applications. 
The sales department at Pumps Inc. complains of unreliable delivery commitments from production. From the head of production, you learn about their high flexibility due to their arrangement as a workshop production facility. Almost all products can be manufactured on all machines. However, in some cases there are long queues in front of the machines.
You are commissioned by the board to analyze processes production to increase delivery reliability and discuss possible causes with them. The technical board member believes that the products are not aligned with the optimal resources in production, in response to which the head of production provides you with a product-process matrix for detailed analysis..
 

More Information

•    Pumps Inc. offers customers 5 different pumps.
•    All pumps go through 3 process steps – “mechanical production,” “electrical production,” and “surface treatment” – before being sent to assembly.
•    For Pump S (only), the mechanical & electrical components are purchased, which means those two steps are omitted.
•    For technological reasons, Pump L can only be produced on the small “mechanical production” machine.
•    For technological reasons, Pump M cannot be produced on Machine 2 in “electrical production”.
•    Moreover, you have confirmed requirements for the next year for each product from the sales department.

Please Note

Interest payments and operating costs can be covered by cargo flight operations, turnover from the multi-story parking garages and rental income, and therefore do not have to be taken into account.

Model Solution and Explanation

What is Required?

Required information:

Construction costs: approx. €5.1 billion
Potential passengers: approx. 26 million (Tegel 19.5 million, Schönefeld 6.5 million)
Turnover per airline passenger: approx €20

What is the Solution?

The solution is:

€20 x 26 million = €520 million
5.1 billion / 0.52 billion
= 9.8 years

What’s the Explanation?

The landing fees* can be found in the AIP (Aeronautical Information Package) GEN4.1 and are based on:
•    Weight
•    Number of passengers
•    Cargo weight
•    Noise class and landing time
Example:
•    737-500, fully occupied (108 passengers) and a landing weight of 47 metric tons with landing
•    Weight: €0.81 per 1,000 kg of the maximum takeoff weight (54 metric tons) = €43.74
•    Passengers: €1.06 per passenger (108) = €117.48
•    Cargo:
€0.14 per 100 kg cargo
•    (e.g. 500 kg of sausages) = €0.70
•    Noise 1:
Base value noise category 3 = €41
•    Landing fees alone*:
€43.73 + €117.46 + €0.70 + €41.00 = €202.89

Add to this:

•    Passenger charge:
€15.90 per passenger = €1,717.20
•    Security charge:
€1.21 per passenger = €130.68
•    Stowage charge:
€90 €

Total €2,140.77* for 108 passengers
approx. €19.82 per passenger
