Study of multilayer structure marketin trucking industry through Agent-based Simulation઒‫ޱ‬ɹ༗඙ 1
Arihiko Kawaguchi111ஜ೾େֶUniversity of Tsukuba

Abstract: In this research, focusing on the hierarchical structure of the truck delivery industry,
several measures to improve the industry structure as a social problem are evaluated with anagent simulation model. As a result, measures such as promotion of fare optimization and delivery
sharing economy have all been eﬀective in improving the profitability of the delivery company.
Meanwhile, it is suggested that the number of players participating in the market increases, andthat negative aspects such as multilayering of the trading hierarchy are increasingly promoted.
