A Simulation Analysis on Garbage Can Model by
using Colored-Petri Nets
-- For Evaluation on Procedure Design of Citizen Participation
in Municipal Comprehensive Planning --
This paper is to deal with efficient management on citizen
participation for municipal planning in Japan, so we revive Cohens' Garbage
Can Model (GCM) through applying it on Colored-Petri Nets (CPN) Software.
Especially, in the case of no-conflict and high-fluidity inside social organization,
Garbage Can Model can be still suitable for the analysis. After explaining
our research context, we present actual 'Garbage-Can' analogy model on Colored-Petri
Nets software, for showing the basis for the audiences especially most of
Japanese people, who sound this metaphor something cynical. Next, we address
Cohens' Garbage Can Model on Colored-Petri Nets software by extending the
'Garbage-Can' analogy model. We also show these two models have a mathematical
relationship of 'model-extension order'. By introducing Colored-Energy concept,
that means specialty each participant can deal, hypothetical participation
procedure structures are to be evaluated through simulation runs under several
different case-setting on mainly access structure among committees. We already
have the results including 'hierarchical structure' much more efficiency than
'flat-pattern structure'. The simulation also suggests that efficient organization
patterns might depend on the fluidity of citizens' attendance, so Average
Citizens' Attendance Ratio (ACAR), so ACAR plays a role to effect the overall
of this model.
