This article explores the decision analysis regarding Drop and Hook (D&H) transportation operation within sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different alternatives of sugarcane delivery systems using internal, external or even not using D&H. D&H strategy maximizes the use of trucks, since semi-trailers can be handled independent of the traction unit of the trucks, which makes the transport system more agile. Internal D&H considers the semi-trailer detaching/attaching point positioned inside the mill site while External D&H is located outside it, before trucks weighting point. Each alternative requires a different infrastructure which affects the supply of sugar cane for milling. The case study was applied to a sugarcane mill of a corporation located in Sao Paulo State. By means of discrete simulation, we found that eighteen alternatives to configure D&H were feasible. By using the swing weight method in MCDA, we found that the fleet cost was the most important, while the alternatives with external D&H showed the best utility values. In the specific case, the best alternative is to use 28 road train (truck and two semi-trailers), 12 extra semi-trailer sets and 6 tractor units with external D&H strategy.
