Resumen:
We describe the development of a decision-support tool to assist in the operations of a large concentrated apple and pear juice plant. The tool?s objective is to generate detailed schedules of clarified juice batches to be produced in the following weeks considering incoming fruit forecasts, commercial commitments, and infrastructural constraints. The tool is based on twointeractive modules, PLANNER and SIMOPT, with different and complementary purposes. Each module is based on mixed-integer models with specific inputs, outputs, and user interfaces. PLANNER consists of three sub-modules: (i) Planning assigns a batch of concentrated juice to be produced a specific day taking into account cleaning activities, rest days, raw material availability, and production and storage constraints, (ii) Pre-Processing organizes juice orders in batches, (iii) Pooling provides a detailed monitoring of semielaboratedjuice in storage pools in terms of inventories, sugar and acid content. Finally,SIMOPT provides a detailed optimal operative condition of the plant together with a thoroughcalculation of specific costs. This information is used by PLANNER to evaluate thecorresponding economic objective functions. Besides providing optimal target conditions to theplant and feasible production schedules, the developed tools generate production guidelines inthe long term and allow performing scenario studies.
