Mode choice between reefer bulk and container in seaborne cold chains for time sensitive products is a practical problem, in which limited studies are available to guide decision makers. This study thoroughly investigates the cold chain mode choice problem by selecting shipping mode (containerized transport and bulk transport) for each shipment and determining shipment quantities and ship deployment in a multi-period planning environment with independent perishable product demands. Value-Based Management as a novel method in shipping is adopted to consider both economic and environmental objectives from operational and financial aspects. The value-based mode selection models also determine the sailing speed of the heterogeneous chartered reefer bulk fleet under different chartering terms. Furthermore, the paper evaluates greenhouse gas emissions from the cold chain shipping. Findings from a numerical example show that optimal ship speed decreases with a reducing rate when the bunker price increases and with a higher decline rate when goods are less perishable.

对于时间敏感产品，在海运冷链中冷藏箱散货箱与集装箱之间的模式选择是一个实际问题，在这一方面，有限的研究可用来指导决策者。这项研究通过为每个装运选择运输模式（集装箱运输和散装运输）并确定装运数量和在具有独立易腐产品需求的多周期计划环境中部署船舶来彻底研究冷链模式选择问题。以价值为基础的管理作为一种新颖的运输方法被采用，从运营和财务方面考虑经济和环境目标。基于价值的模式选择模型还确定了不同租赁条款下的异构特许冷藏集装箱散装船队的航行速度。此外，本文评估了冷链运输产生的温室气体排放量。数值示例的结果表明，当燃油价格上涨时，最佳船速以降低的速度降低，而当货物不易腐烂时，最佳船舶速度以较高的下降速度降低。
