Farms are the first link in the supply chain of flower exports. Such a supply chain begins with both the flower cutting and the receipt of customer orders and finishes with the delivery of flowers at their international destinations. The purpose of this paper is to investigate the right mix of fixed vs. same-day orders (Open market). Too many same-day orders imply higher profits but also high risks of not delivering the product on time and to face longer queues at the airport; too few same-day orders imply lower profits. This problem is a special case of revenue management and in its basic form corresponds to the well-known newsboy problem. This study is intended to create awareness among flower growers that poor practices at the farm itself have a significant impact on the whole supply chain. We also developed a mathematical model of the farm business and logistics processes to quantify the impact of the main factors on the performance of the flower deliveries. The model is solved numerically. The results of the model were analyzed with formal analysis tools. The findings of the study have been used to establish realistic standards and best practices by the main association of flower growers in the country and can be extended to other emerging countries.
