Production
Every day the dairyman receives a production plan from Raffaella, containing instructions on the cheese he needs to produce for the day.
To determine the ingredients to use for a production the dairyman uses a recipe book where, for each type of cheese, there is a recipe. A recipe specifies the quintals of each ingredient needed to produce a quintal of the given type of cheese.
e.g. The recipe for a quintal of ricotta requires 1.5 quintals of milk, a tenth of quintal of rennet and a tenth of quintal of salt
Once the appropriate recipe is chosen the production can start by retrieving the needed ingredients.
Once an in-progress production ends (the smart machines will send an appropriate message to signal the end of the process), the produced cheese is assigned a batch ID and stored in a refrigeration room.
