Topic 9.1.1: Availability & Allocation

  • Equipment Availability
    • A system tag is automatically generated for each unit or segment defined in the process model. The equipment statuses define the possible values of this system tag.
    • The statuses are used by the InBatch Management System when it evaluates the availability of a unit or connection.
    • The availability of a unit is determined by the current status. If the status is available, the InBatch Management System can allocate the unit.
    • If the status is not available, the unit cannot be allocated. The availability of a connection is determined by the current status of all of the segments that comprise the connection.
    • If a connection does not contain one or more segments, the connection is always available.
  • Allocating Equipment
    • To run any phase as part of a batch, equipment must be allocated to the batch. If suitable equipment had been previously allocated to the batch, that equipment is used.
    • If equipment has was not been previously allocated, the InBatch Management System must allocate suitable equipment to the batch before it can proceed with phase processing.
    • The three approaches to allocating equipment for a batch are described in the information that follows.
