A combinatorial weighing method and apparatus wherein a value serving as a target for a combinatorial computation is set so that the mean weight value of batches of articles weighed out selectively by plural weighing cycles becomes equal to a preset weight value within preset allowable limits. Combinatorial computations are performed while diminishing the target weight value by a predetermined amount when the mean weight value is greater than the preset weight value, and increasing the target weight value by a predetermined amount when the mean weight value is less than the preset weight value.

A combinatorial measuring method comprising the steps of: (a) determining, during a weighing cycle, the weights of a plurality of batches of articles, and providing weight values corresponding to the respective weights of the batches of articles; (b) performing, during a weighing cycle, combinatorial computation based on the weight values provided in said step (a) to select the combination of batches having a total combined weight value which is closest to a target weight value within preset allowable limits; (c) selectively calculating a means weight value for the total combined weight values corresponding to the combinations selected in said step (b) during a plurality of weighing cycles; (d) adjusting the target weight value so that the mean weight value approaches a preset weight value which is within the preset allowable limits, said adjusting step comprising the substeps of: (i) diminishing the target weight value by a predetermined amount when the mean weight value is greater than the preset weight value; and (ii) increasing the target weight value by the predetermined amount when the mean weight value is less than the preset weight value.
