The Future of Smart Manufacturing
Imagining the future of smart manufacturing
Ten conjectures
A. Kusiak, Smart Manufacturing, IJPR 2017 (published online)
The University of Iowa Intelligent Systems Laboratory
Conjecture 1

Justification Manufacturing could benefit from wind energy and process
industry where supervisory control and data acquisition (SCADA) systems have been used to capture, store, and sharedata

Conjecture 2
Increased Need for Modeling, Optimization, and Simulation Delivery of value from manufacturing data
Justification Data flow across different domains (e.g., product,
process, and logistics) Dynamic and predictive models Virtual and augmented reality

Conjecture 4
Vertical Separability of the Physical Assets and the Cyberspace The physical and the logistics layers to be designed
for ease and speed of connecting and disconnecting
Justification The need to reconfigure physical assets driven by
the changing product needs
The University of Iowa Intelligent Systems Laboratory
Conjecture 5
Enterprise Dichotomy Two extreme smart enterprise models may emerge, one where
the physical and logistics layers are tightly horizontally connected and the other with vertical separability of the two layers
Justification The horizontal connectivity and the vertical separabilty models
may emerge as the result of Conjecture 3 and Conjecture 4, respectively
The University of Iowa Intelligent Systems Laboratory
Conjecture 6
Horizontal Connectivity and Interoperability Increase of horizontal internal and external connectivity

Justification The growing volume and flow rate of data across
an enterprise will naturally lead to greater horizontal connectivity and interoperability

Resource Sharing Sharing manufacturing and transportation resources
across manufacturing chains will become a common practice
Justification Horizontal connectivity combined with dynamic
markets will facilitate sharing manufacturing equipment, transportation, and other resources

routine. Autonomous repair will occur.
Justification Sensors will provide data to monitor and predict health status
of equipment and systems.

meet the emerging needs of integration and interconnectivity
Justification Growing reliance on data (Conjecture 1), resource sharing
(Conjecture 7), and the need for vertical separabilty (Conjecture 4) and horizontal connectivity and interoperability (Conjecture 6) will drive the need for standardization and collaboration
