ABSTRACT
In the preceding chapters, we focused on how the machines, workstations, and auxiliary and support services need to be placed relative to one another to maximize manufacturing effi ciencies related to material fl ow. Now, it is time to turn our attention to the systems that actually transfer material among the machines, workstations, and support services. These systems are referred to as material handling systems (MHSs). The facility design problem not only includes the selection and placement of manufacturing equipment but also that of the MHS. In a typical manufacturing company, multiple material handling devices (MHDs) are used in combination to form a material handling system. It is not uncommon to see the same product handled by various types of MHDs between multiple processing stages. For example, in an underground transformer manufacturing facility, industrial trucks are used to transport the sheet metal from a central storage area to the preliminary processing area. The sheet metal is cut into smaller pieces at the sheet metal processing area. These panels are moved via conveyors to a fabrication area. After the panels are welded to form a housing and the electrical assembly is placed in the housing, they gradually become bulkier and heavier, and require transportation by hoists.
