Attaining stability in multi-skill workforce scheduling
Murat Firat

We define a set inequalities that are to be satisfied by stable multi-skill 
workforce schedules. In our analysis, a schedule is said to be stable if it 
does not contain a blocking pair, extending the notion of blocking pair in the 
Marriage Model of Gale-Shapley. Skill efficiency is chosen as the criterion in 
the preference structure. The proposed algorithm either constructs a stable 
multi-skill workforce schedule or decides that no stable schedule exists.
