We consider a production-inventory system that consists of an input-generating installation, a production unit and L intermediate buffers. It is assumed that the installation transfers the raw material j ∈ {1, . . . , L} to buffer Bj, and the production unit pulls the rawmaterial j ∈ {1, ..., L} from buffer Bj. We consider the problem of the optimal preventive maintenance of the installation if...
