A tandem expert system for batch scheduling in a CIM system based on group technology concepts

Hierarchical Scheduling of Mobile Robots in Production-Transportation Supply Chains

“…The scheduling problem will be formalized as a generalization of the multi-machine Johnson problem and solved by combining a combinatorial algorithm with expert rules. The approach suggested may be considered as a further development of scheduling techniques for PERT-type projects with time lags and overlapping, previously investigated in the literature (see, for example, among others, Elmaghraby and Kamburowski 1992;Levner and Nemirovsky 1994;Levner et al 1995aLevner et al , 1995bLevner et al , 2007Crama et al 2000).…”

Cyclic Scheduling in Robotic Cells: An Extension of Basic Models in Machine Scheduling Theory

“…For completeness, we might mention three more groups of robotic (non-cyclic) scheduling problems which might be looked at as "atomic elements" of the cyclic problems: Robotic Non-cyclic Flowshop (Kise (1991), Levner et al (1995aLevner et al ( ,1995b, Kogan and Levner 1998), Robotic Non-cyclic Jobshop (Hurink and Knust (2002)), and Robotic Non-cyclic PERT-shop (Levner et al (1995c)). However, these problems lie out of the scope of the present survey.…”
