Three essays on production planning under uncertainty are presented. First, capacity planning under different flexibility options is solved with a mixed-integer linear program. Second, a stochastic capacitated lot-sizing and a stochastic general lot-sizing and scheduling problem including endogenously set safety stocks are addressed. Several sequential and integrated models are proposed and evaluated under rolling horizon planning. While sequential approaches enable to obtain solutions fast, integrated approaches offer further cost-savings.
