describe the connecting relationship between equipment, control policy and so on.
Then, programs for machine agents and descriptions for the virtual production lines
are generated automatically (Matsuda et al. 2016).
An e-catalogue of equipment is a group of one template and equipment items
which are created using the template. The equipment template and/or equipment
items are registered in a shared repository. An equipment template and an equipment
item are required to include descriptions which specify properties, behavior resulting
from equipment’s activities, and communications with outside and/or other equipment. An equipment template is a schema representing a model for each equipment
type including behavior. An equipment item is an instance of an equipment template
filled with values. An equipment item is a model of a specific equipment. Template
and item are implemented using a data description language such as XML or JSON.
35.3 Preliminary Study on Printed Circuit Assembly
35.3.1 A Digital Eco-Factory for Printed Circuit Assembly
A proposed multi-agent based construction of the digital eco-factory is applied to a
PCA line and a trial digital eco-factory has been implemented as shown in Fig. 35.3.
An e-catalogue creation system was prepared for supporting this trial. E-catalogues
for a solder paste printer, an electronic part mounter and a reflow soldering oven
were prepared using this system. When the simulation on the digital eco-factory is
executed, input of a production scenario such as product data, schedule and operation
data are required. These data affect the equipment behavior. The digital eco-factory
for PCA is structured on a commercially available multi-agent simulator “artisoc”
[13]. Figure 35.4 shows a screen shot of the simulation execution example using the
generated virtual production of the PCA. In this example, there are two production
lines. The graphs in the left column show conditions of line 1 and the right column
shows conditions of line 2. The graphs in the second row show changes in the number
of PCBs on the lines and change in the number of finished PCAs. The graphs in the
third row shows changes in energy consumption of each machine. The graphs in
the bottom row shows the total amount of energy consumption of each machine
(Matsuda et al. 2015, 2016).
35.3.2 Summary of Preliminary Study
The trial digital eco-factory was used in a few industries as an experiment. As a result,
the practical usefulness was confirmed especially about time qualitative changes of
environmental performance. This trial shows how to construct the digital eco-factory
with accuracy and high usability. This trial also shows prominent maneuverability at
