A combinatorial weighing method for obtaining a mixture of articles of plural categories, wherein the articles in each category are contained in the mixture at a number ratio equal or closest to a target number ratio, and wherein the mixture has a total weight equal or closest to a target weight. The method includes setting a number for each category of articles so as to provide a number ratio closest to a target number ratio, and measuring the total weight of a primary mixture obtained by extracting the set number of articles in each category and mixing these articles. A weight shortfall, which is the difference between the total weight of the primary mixture and the target weight, is computed, and a plurality of weighing machines are supplied with supplemental articles to make up for the shortfall. An optimum combination of weighing machines giving a weight equal or closest to the shortfall, is selected and a final mixture is obtained by discharging supplemental articles from the selected weighing machines and mixing these articles with the primary mixture.

A combinatorial weighing method for obtaining a final mixture of articles of plural categories, in which the articles in each category are contained in the mixture at a number ratio equal or closest to a target number ratio, the final mixture having a total weight equal or closest to a target weight

A combinatorial weighing method for obtaining a final mixture of articles of plural categories, in which the articles in each category are contained in the mixture at a number ratio equal or closest to a target number ratio, the final mixture having a total weight equal or closest to a target weight, said method comprising the steps of: (a) setting a number of articles for each category of articles to provide a primary number ratio close to the target number ratio; (b) measuring the total weight of a primary mixture obtained by extracting the set number of articles in each category determined in said step (a) and mixing these articles together; (c) computing a weight shortfall by finding the difference between the total weight of the primary mixture and the target weight; (d) supplying a plurality of weighing machines with supplemental articles which are used to compensate for the weight shortfall, and selecting an optimum combination of weighing machines giving a combined weight equal or closest to the weight shortfall; and (e) obtaining a final mixture by discharging the supplemental articles from the selected weighing machines forming the optimum combination and mixing these supplemental articles with the primary mixture.
