Claim 4:
5. A combined weighing program that causes a computer of a management device to execute functions in a combined weighing system including a first X-ray inspection device that irradiates articles with X-rays to acquire first X-ray images, detects weights of the articles based on the first X-ray images and a weight conversion table set in advance, and inspects whether or not an average value over a certain time period of unit weight values is in an allowable weight range, the unit weight value representing a weight of one article,
a combined weighing device that performs combined weighing on the articles, which have been inspected by the first X-ray inspection device, so as to acquire a weight obtained by adding a correction value to a combination lower limit value, and supplies the articles on which the combined weighing has been performed,
a packaging device that packages a plurality of the articles, which are combined by the combined weighing device, in a bag,
a weight inspection device that inspects weights of packages in each of which the plurality of articles are packaged in the bag,
a second X-ray inspection device that irradiates the packages, which have been inspected by the weight inspection device, with X-rays to acquire second X-ray images, and inspects the number of the plurality of articles in each of the packages based on the corresponding second X-ray image, and
the management device that manages each device,
wherein the weight conversion table of the first X-ray inspection device and the correction value of the combined weighing device are revised based on an average value of the weights of the packages, which is calculated from a result of the inspection over a certain time period in the weight inspection device.
