Abstract: A semiconductor bullet lot dispatch system is provided. The semiconductor bullet lot dispatch system includes a plurality of lots having bullet lots and non-bullet lots, and a processing site having a plurality of load ports used to run the lots. The semiconductor bullet lot dispatch system also includes a bullet lot arriving time initial module configured to collect work flow information of the lots and calculate bullet lot arriving time intervals; and a port remaining time initial module configured to calculate port next available time intervals. Further, the semiconductor bullet lot dispatch system includes a future constraint check module configured to match the bullet lots with the load ports, and a bullet lot scenario engine module configured to calculate a total available lot count of each of available load ports and dispatch the bullet lots to the load ports.

Abstract: A portable structure (1), configurable between stored and erected conditions, comprises a base (4), one or more sides (5), a resilient frame (2) and one or more spacing members (6). The base (4) and the one or more sides (5) comprise a flexible material. The resilient frame (2) is located at the interface of the base (4) and the one or more sides (5). The resilient frame (2) is connected to the flexible material to provide a shape to the base (4) in the erected condition. The one or more spacing members (6) support the flexible material of the one or more sides (5) in a raised manner in the erected condition so as to form a container, bounded by the flexible material of the base (4) and the one or more sides (5).
