本研究針對：「機械式冷凍車廂區隔」與「抽換式蓄冷保溫箱」兩種低溫物流之多溫共配系統進行其車輛路線問題之測試與分析。上述兩種多溫共配系統的車輛路線排程有別於傳統車輛路線問題（Vehicle Routing Problem, VRP），須同時考慮車廂與保溫箱之裝載等因素；再加以實務業者多為多車種之車隊。因此，本研究將其車輛路線問題稱之為「多車種多溫共配車輛路線問題」(Heterogeneous Multi-temperature Fleet Vehicle Routing Problem, HMFVRP)。為 Recently, the demand of the cold logistics and the multi-temperature distribution has rapidly grown. This paper considers two special operational situations: first, carriers utilize the engine-driven frozen truck divided into three parts to hold different
