 The purpose of
this course, IE 551, is to give graduate Industrial and Manufacturing Engineering students
exposure to the basic and modern control and architecture issues concerning
the construction of a Computer Integrated Manufacturing (CIM) environment.
Detailed discussions and planning activities centered on the following
topics: (1) CIM architecture and Flexible Manufacturing Systems (FMS), (2)
Process, workstation, and shop-floor control issues, (3) Process planning,
(4) Finite state based modeling, (5) Scheduling, and (6) Deadlocking.
This course
includes the construction of an Arena simulation for real-time control of the
CIM environment, an Access 2000 database to store system, part, and ordering
information, data driven controllers and a Message-Based Part State Graph
(MPSG) - a finite state based model to define possible actions occurring in
the system, and representation models for process plans and factory
resources. Generation of the supervisor, workstation, and equipment
level controllers was accomplished using the MPSG code generator. This
C++ based code generator provides a "user-friendly" platform for
the development of a formal messaging and communications system between the
different resources (workstation / equipment level controllers) and the
real-time Arena 3.0 simulation and Big E (supervisory controllers). The
protocol generated with the MPSG system allows for the communication and
execution of a set of sequential control events (e.g. input / output
information about the resources current jobs / status and executable tasks).
