abstract = "This paper presents a methodology, called production
system identification, to produce a model of a
manufacturing system from logs of the system's
operation. The model produced is intended to aid in
making production scheduling decisions. Production
system identification is similar to machine-learning
methods of process mining in that they both use logs of
operations. However, process mining falls short of
addressing important requirements; process mining does
not (1) account for infrequent exceptional events that
may provide insight into system capabilities and
reliability, (2) offer means to validate the model
relative to an understanding of causes, and (3) updated
the model as the situation on the production floor
changes. The paper describes a genetic programming (GP)
methodology that uses Petri nets, probabilistic neural
nets, and a causal model of production system dynamics
to address these shortcomings. A coloured Petri net
formalism appropriate to GP is developed and used to
interpret the log. Interpreted logs provide a relation
between Petri net states and exceptional system states
that can be learned by means of novel formulation of
probabilistic neural nets (PNNs). A generalized
stochastic Petri net and the PNNs are used to validate
the GP-generated solutions. The methodology is
evaluated with an example based on an automotive
assembly system",
