Solution. Transshipment (#143)
Answer: 2
Solution
According to the problem, a specialized vessel, instead of completing a round trip to the delivery port, can complete exactly two round trips to the transshipment complex using the same time.
Thus, this vessel, instead of transporting one shipment, will transport two shipments, thereby ensuring the additional shipment per month.
It is important to note that there are no restrictions on logistics between the transshipment complex and the delivery port. In other words, conventional vessels are assumed to be always available.
