Unfortunately in the original version of the article the information of the second author Mr. Marco Schulze was published incorrectly.

Previously read as

Clausthal University of Technology, 34131 Kassel, Germany

It should read as

K+S Aktiengesellschaft, 34131 Kassel, Germany

In Constraint (16) (on the 13th-page), there is some space before \(\forall b \in \mathcal{B}: x_{bt} \in \{0, 1\} \quad \forall b \in \mathcal{B}, \forall t \in \mathcal{T} \)

The original article has been corrected.
