I am looking for a name for that problem in literature! (and if you know literature also it would be great) I did not find it and given the wide audience here, maybe you know more. Thank you $$ min_x max_k \sum_{i,j}c_{ijk}x_{ij} \quad k = 1 ... d $$ $$ \sum_{j} x_{ij} = 1 \quad i = 1...n $$ $$ x_{ij} \in \{0,1\} $$
