3 Limitations
3.1 The Material Transport and Storage Component
provides AMHS Framework level interfaces to
interoperable AMHS Equipment. This level of material
transport is factory level movement, i.e., the transport
of product and durables between machines, areas or
material tracking locations. The Material Tracking and
Storage Component does not provide interfaces that
make material movement within machines visible.
3.2 Provisional Status — This specification is
designated as provisional due to known areas that need
to be completed. The following items summarize the
deficiencies of the provisional specification to be
addressed before a subsequent ballot to upgrade it to
full standard status.
3.2.1 Dependence on Global Declarations and
Abstract Interfaces — Components of this document
reference global declarations and specialize abstract
interfaces for material, resource and job concepts. The
provisional specification for these declarations and
interfaces was balloted and recommended by the SEMI
Information and Control Committee in July, 1999.
When this specification is published a revision will be
undertaken to clearly define the relationship of this
specification to those common elements of the CIM
Framework.
3.2.2 Dependence on Durables Management
Component — The Material Transport and Storage
Component depends upon interfaces specified as part of
the Durables Management Component of the CIM
Framework. This document includes only the required
interfaces from Durables Management. Those
interfaces, found in Section 6.2.3, will be removed from
this document when the Durables Management
Component of the CIM Framework is adopted in a
future ballot.
3.2.3 Dependence on Machine Abstract Interface
Group — The Material Transport and Storage
Component depends upon interfaces specified as part of
the Machine Abstract Interface Group (Machine AIG)
of the CIM Framework. This document includes only
the required interfaces from the Machine AIG. Those
interfaces, found in Section 6.2.4, will be removed from
this document when the Machine AIG of the CIM
Framework is adopted in a future ballot.
3.2.4 Dependence on Factory Operations Component
— The Material Transport and Storage Component
depends upon interfaces specified as part of the Factory
Operations Component of the CIM Framework. This
document includes only the required interfaces from the
Factory Operations Component. Those interfaces,
found in Section 6.2.5, will be removed from this
document when the Factory Operations Component of
the CIM Framework is adopted in a future ballot.
3.2.5 Deterministic Prediction of Transport Time —
The responsibility for providing estimates of predicted
transport time of future TransportJobs in a deterministic
way is beyond the scope of the Provisional
Specification. This capability may be offered in future
upgrades of this specification based on added
experience with such predictions. It may be found that
heuristic methods for transport time prediction are the
most practical way to provide such estimates.

6.1 The following sections specify the interfaces that
comprise the Material Transport and Storage
Component of the CIM Framework. Additionally, the
subsets of interfaces from Durables Management,
Machine Abstract Interface Group, and Factory
Operations required to support Material Transport and
Storage are included here pending future ballots that
will address the full scope of these other specifications.

of Transport Jobs. The Material Transport and Storage
Component uses services provided by the Machine AIG
to access interfaces of Machines and Ports that serve as
the source or destination of Transport Jobs. The MES
Factory defines areas within a factory which represent
groups of machines. Finally, Durables Management
provides the services needed to manage the material
containers that are moved.
6.1.2 Figure 3 shows the Material Transport and
Storage Component information model, including the
inherited interfaces and the associations between
interfaces. These interfaces are fully defined in Sections
6.3 and 6.4. The interfaces associated with the Material
Transport and Storage are as follows:
1. TransportJobSupervisor – abstract interface,
2. MaterialTransportManager,
3. MaterialTransportController, and
4. TransportJob.
6.2 Required Subsets of Future CIM Framework
Specifications
6.2.1 This specification depends on interfaces from
Durables Management Component, the Machine
Abstract Interface Group and the Factory Operations
Component that will eventually be contained in future
CIM Framework component specifications. They are
included with this document to support a complete
specification for AMHS support within the CIM
Framework. When these items are balloted as separate
documents, they will be removed from this
specification and referenced in their full form.
