Zusammenfassung: 
A branch & bound algorithm is presented for a very general scheduling problem with n jobs and m machines. Each job consists of a set of operations. Each operation has to be processed on a dedicated machine. There may be arbitrary precedence relations between the operations. The set of all operations is partitioned into groups. If on a machine an operation belonging to group G(g) is processed immediately after an operation belonging to group G(f) there is a setup of s(fg) time units. We assume that s(fg)=0 if f=g and that the s(fg) satisfy the triangle inequality. Computational results for this general problem as well as for special cases like the job-shop problem and the open-shop problem are reported.
