Optimal transport to cold chain in perishable hand-picked agriculture

Research output: Contribution to journalArticlepeer-review


We develop and analyze a model for scheduling transport for perishable products. Once the harvest is picked, its quality starts to deteriorate, eventually having no value. In hand-picked crops, the rate of picking often varies during the day. One would like to transport the harvest to a cooling station (cold chain), but to do so according to an optimal policy. This optimal policy should reflect a trade-off between the loss of quality and the rate of harvest, and the fact that only a finite number of transports can be scheduled. We model the harvest and loss of quality and arrive at a computationally solvable optimization problem.
