Method, in a production process using a set of ingredients, for automatically optimizing the time necessary for a scale to weigh said ingredients, characterized in that it comprises the following steps: • for each ingredient of the set, ∘ obtaining a weighing tolerance; ∘ determining a readability parameter of the scale according to the weighing tolerance, wherein the readability parameter relates to a lowest level by which a weight can be read, and is typically expressed in grams; wherein said readability parameter is determined by: ▪ determining an optimal readability parameter according to the weighting tolerance and a safety factor, wherein the optimal readability parameter is determined by multiplying an expected weight of said ingredient with weighing tolerance and then dividing by the safety factor; ▪ obtaining a readability set of available readability values for the scale; ▪ if the optimal readability parameter is smaller than a highest available readability values of the readability set, setting the readability parameter to the highest available readability value of the readability set that is inferior or equal to the optimal readability parameter; ▪ if the optimal readability parameter is greater than or equal to the highest available readability values of the readability set, setting the readability parameter to the highest available readability values of the set; ∘ before weighing said ingredient, configuring the scale according to the readability parameter. • for each ingredient of the set, ∘ obtaining a weighing tolerance; ∘ determining a readability parameter of the scale according to the weighing tolerance, wherein the readability parameter relates to a lowest level by which a weight can be read, and is typically expressed in grams; wherein said readability parameter is determined by: ▪ determining an optimal readability parameter according to the weighting tolerance and a safety factor, wherein the optimal readability parameter is determined by multiplying an expected weight of said ingredient with weighing tolerance and then dividing by the safety factor; ▪ obtaining a readability set of available readability values for the scale; ▪ if the optimal readability parameter is smaller than a highest available readability values of the readability set, setting the readability parameter to the highest available readability value of the readability set that is inferior or equal to the optimal readability parameter; ▪ if the optimal readability parameter is greater than or equal to the highest available readability values of the readability set, setting the readability parameter to the highest available readability values of the set; ∘ before weighing said ingredient, configuring the scale according to the readability parameter. ∘ obtaining a weighing tolerance; ∘ determining a readability parameter of the scale according to the weighing tolerance, wherein the readability parameter relates to a lowest level by which a weight can be read, and is typically expressed in grams; wherein said readability parameter is determined by: ▪ determining an optimal readability parameter according to the weighting tolerance and a safety factor, wherein the optimal readability parameter is determined by multiplying an expected weight of said ingredient with weighing tolerance and then dividing by the safety factor; ▪ obtaining a readability set of available readability values for the scale; ▪ if the optimal readability parameter is smaller than a highest available readability values of the readability set, setting the readability parameter to the highest available readability value of the readability set that is inferior or equal to the optimal readability parameter; ▪ if the optimal readability parameter is greater than or equal to the highest available readability values of the readability set, setting the readability parameter to the highest available readability values of the set; ▪ determining an optimal readability parameter according to the weighting tolerance and a safety factor, wherein the optimal readability parameter is determined by multiplying an expected weight of said ingredient with weighing tolerance and then dividing by the safety factor; ▪ obtaining a readability set of available readability values for the scale; ▪ if the optimal readability parameter is smaller than a highest available readability values of the readability set, setting the readability parameter to the highest available readability value of the readability set that is inferior or equal to the optimal readability parameter; ▪ if the optimal readability parameter is greater than or equal to the highest available readability values of the readability set, setting the readability parameter to the highest available readability values of the set; ∘ before weighing said ingredient, configuring the scale according to the readability parameter.
