Time Pattern—a collection of calendar values, shift states, or other time patterns that
have been assigned to specific blocks of time. For example, a time pattern named First
Shift might define time blocks 8 to 12 as Available, 12 to 13 as Unavailable, and 13 to
17 as Available. Time patterns are building blocks that are used to construct complete
work schedules for a resource.
Transfer—the movement of a production lot from one work cell station to the next work
cell station. Transfers between stations can be performed using conveyors, transport-
ers, or simple routes.
Transporter—a discrete transfer device that moves production lots from one station to
the next. A transfer via a transporter requires an available transporter device.
Transporters come in many different types including carts, cranes, forklift trucks, and
AGVs. Transporters can operate in both free-path and fixed-path modes.
Utilization—the fraction of time that a resource is being used by a production lot.
Work Cell—a location and/or group of equipment used to perform work in a manufactur-
ing process. The operations in a manufacturing process are performed at work cells. A
work cell typically is a physical location of a primary resource (e.g., a machine);
however, it may also represent a logical grouping of primary resources from which a
selection is made. A main production capability (e.g., Inspection) and designated loca-
tion number (e.g., #1) usually identify a work cell.
Work-in-Process (WIP)—the total number of production lots in a work cell, area, line,
site, or enterprise.
