On the importance of sequencing decisions in production planning and scheduling
(Discussion paper1999:7, Working paper, 1999-06)
We discuss the traditional hierarchical approach to production planning and scheduling, emphasizing the fact that scheduling constraints are often either ignored or considered in a very crude way. In particular, we point ...
Extensions of an integrated approach for multi-resource shop scheduling
(Discussion paper1999:6, Working paper, 1999-06)
In a previous work, we proposed an integrated approach for a rather general shop scheduling problem, with multi-resource, exibility and non-linear routings. In this paper, we want to overcome some of the limitations of the ...
Using lagrangean relaxation to minimize the (weighted) number of late jobs on a single machine
(Discussion paper1999:8, Working paper, 1999-06)
This paper tackles the general single machine scheduling problem, where jobs have different release and due dates and the objective is to minimize the weighted number of late jobs. The notion of master sequence is first ...
