Approaches to analysing the load routing problem in tandem AGV systemsIt has been estimated that between 20–50% of the total operating cost within manufacturing can be attributed to material handling. Furthermore, effective facilities design and planning can reduce these costs by at least 10–30% (Tompkins and White, 1984). Even so, material handling is often an overlooked aspect of factory operations.

Reachability in material flow path designThe material flow path layout design is one of the most important variables in designing carrier-based material handling systems. The guide path layout design process includes the selection of lanes among candidate aisle spaces and determination of the flow directions of lanes.

W. Hort,G. Arnold,H. FrenzelThis catalogue and atlas contains information on 277 objects, mainly classical novae and related objects (recurrent novae, X-ray novae, dwarf novae with long cycle lengths, symbiotic stars and suspected new stars). For most objects, brightness ranges, accurate positions, finding charts and selected bibliographies are given.
