Pattern-based Manufacturing Optimization (PbMO) goes
beyond that and proposes concrete process modifications
that are applicable for a given process to achieve a defined
goal, e. g., to speed up the process. PbMO is based on the
idea of pattern-based optimization presented in [3] and uses
manufacturing-specific optimization patterns stored in the
Manufacturing Pattern Catalogue. These patterns describe
typical optimization options, i. e., best practices, and encapsulate
necessary analytics, esp. data mining models. One
pattern for example describes the optimal selection of resources
for a production step using multiple regression.
Resource attributes like the experience of an employee are
linked with performance indicators, e. g., the execution duration
of a production step, in a regression model to predict the
likely performance and select the best resource available.
IbMO as well as PbMO can be applied ex-ante in the a
priori design, real-time during the execution and ex-post in
the a posteriori analysis of a manufacturing process. In the
following sections we focus on IbMO, esp. the use case of
root cause analysis, since PbMO still requires significant
research efforts, esp. considering the definition of appropriate
optimization patterns in manufacturing.
Both the Manufacturing Warehouse and the data mining
use cases for IbMO and PbMO are designed to be flexibly
adaptable to heterogeneous manufacturing environments
during the instantiation of the AdMA Platform in a concrete
application environment. The essential conceptual difference
to existing data mining approaches is the holistic view on the
manufacturing process comprising all production steps,
resources as well as all input and output relations of the
whole process from the creation of the production order until
the finishing of the product in order to optimize the overall
manufacturing process in an integrated manner.
In general, our work can be seen as an application of process
mining [26] to manufacturing. At this, we do not focus
on the classic process mining disciplines, namely discovery
and conformance of process models, but on the enhancement
of existing process models in order to improve them. In
contrast to traditional enhancement approaches, we use not
only process data but also operational data.
