Abstract:
-
With the increasing levels of automation in factories, production
management systems need increasingly sophisticated models of
manufacturing processes. A framework is presented for the design and
implementation of process reasoning modules which characterize
processes within a manufacturing environment. Each reasoning module
describes a process in terms of its effects, constraints, and process
parameters. The effects include intended objectives, such as material
removal, and side effects such as burr production. Constraints
include specific limits on process parameters, and preconditions to
the invocation of a process. These preconditions can require the
execution of several other processes, leading to the chaining of
events. The process parameters provide qualitative and quantitative
information necessary to execute a process.
