Sugar cane transportation in Cuba, a case study
In this study the authors present a mixed integer linear programming model to solve the problem of cost minimization of sugar cane removal and its transport from the fields to the sugar mill at operational level. The complexity of the problem is basically determined by the system approach which results in the generation of a great number of variables and constraints that refer to the following operational dimensions: (a) need for continuous supply to the sugar mill; (b) cutting means used in cane harvesting; (c) transportation vehicles and (d) providing routes, which are characterized by the existence of storage facilities at the beginning of the railroads. The results demonstrate the model is not only useful to minimize transportation cost, but also for scheduling daily cane road transport and harvesting quotas of cutting means.
