Abstract

This work focuses on tanks’ wine transfers in a winery that are part of the production process of the wine before being bottled. During peak production periods, the winery may face a shortage of available tanks, resulting in unnecessary transfers and increased water usage for tank cleaning as well as higher energy consumption. To address this issue, a mixed integer optimization model has been developed to reduce water and energy consumption by making only the necessary movements, using the minimum number of tanks, and covering the shortest distance. The model is based on three critical elements: the production planning, the tanks, and the route for the wine production. The production planning defines what and when must be produced and the initial mixtures for each class of wine. The ordered sequence of stages to produce each type of wine defines a route. Each stage requires tanks to keep the source and the resulting product. The model ensures each product follows the defined order, using only the necessary tanks and covering the shortest distance. The non-overlapping of tanks is guaranteed, which can be reused once they are empty and clean. The duration of each operation is considered, including transfer time and cleaning after each use. Furthermore, the model ensures that tanks are filled up following wine requirements at each stage to guarantee the quality of the final product. The application of the model is demonstrated in a variety of realistic examples.
