การพัฒนาแบบจำลองระบบหลายตัวแทนเพื่อการประเมินนโยบายการกระจายสินค้าและโลจิสติกส์ในเขตเมือง

Abstract

The Multi-Agent Systems (MAS) model is used to evaluate policy schemes to study the behaviour of stakeholders in the logistics systems. In general, the transportation costs are very important to the trading business especially, they are a factor in determining the cost of goods. Moreover, the transportation and logistics in urban areas also causes traffic congestion and increased air pollution. Consequently, this research aims to study the impact of the distribution center, parking charge and road pricing policies on the behaviour of logistic's stakeholders. From the MAS analytical, the distribution center policy can reduce the cost of freight by 3.99 times, reduce the number of vehicles used by 3.75 times, reduce the distance and air pollution by 3.78 times but increased truck capacity by 4.30 times. Besides considering the cost of adding a parking charge policy and road pricing policy, they can also reduce the transportation costs even though, they charge 15 Bahts per box and 5 Bahts per box when considering parking charge policy and road pricing policy respectively. Moreover, all implemented policies can be reduced the transportation cost and the UDC can be earned the profit although they charge 15 Bahts. However, the construction of a distribution center requires the investment and maintenance of the distribution center. This should be supported by the government to reduce the costs, traffic congestion in urban areas and air pollution as well.
