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.
