This paper addresses the transient multi-hoist scheduling problem in flexible manufacturing facilities and focuses on Lot Switching. The problem arises in electroplating lines with multiple hoists operating on shared tracks. Due to a flexible production different products need to be manufactured which differ in the routing and processing times. The(More)
This paper addresses the forming of Mixed Integer Linear Programming (MILP) models for factory scheduling. Relation Matrices using Allen's temporal relations for qualitative relations between the single operations of each job are developed. Extensions of the basic temporal relations are introduced to model resource constraints for different shops. The MILP(More)
