A constraint programming-based iterated greedy algorithm for the open shop with sequence-dependent processing times and makespan minimization

In this paper, a novel variant of the open shop scheduling problem where the jobs have sequence-dependent processing times is addressed. The performance measure considered is the minimization of the length of the schedule (makespan). This problem …

A new two-stage constraint programming approach for open shop scheduling problem with machine blocking

In this paper, a variant of the open shop scheduling problem is considered in which the intermediate storage is forbidden among two adjacent production stages (zero buffer or machine blocking constraint). The performance measure is to minimise the …

Heterogeneous Prestressed Precast Beams Multiperiod Production Planning Problem: Modeling and Solution Methods

A prestressed precast beam is a type of beam that is stretched with traction elements. A common task in a factory of prestressed precast beams involves fulfilling, within a time horizon, the demand ordered by clients. A typical order includes beams …
