  • Patent number: 12260355
    Abstract: A computer device implements a method of dimensioning a new plant for production of packaged dairy products by simulation. The method operates by obtaining a production target for dairy products to be produced and packaged in the production plant, by obtaining recipes for production of the packaged dairy products, where each recipe defines ingredients and recipe activities, and by obtaining production unit data that associates each of a plurality selectable production units with one or more unit activities and a production capacity. The method further performs the simulation by generating, as a function of the recipes and the production unit data, combinations of selectable production units that are connected for fluid communication and operable to perform the recipe activities of the respective recipe to achieve the production target, and evaluating the combinations for selection of at least one combination representing a plant configuration.
