Abstract
A certain type of weighing systems consisting of plural scales is referred to as a “combinatorial weigher”, with which the calculation in the combination of the measured values in carried out and a combination of the objects within a tolerance in mass value is produced. The combinatorial weigher dealt with in this paper consists of one scale for object-A and eight scales for object-B. In the combination process with the weigher, some unique phenomena in probability and statistics, so to speak, “synergy” can be found. By the aid of computer simulation, we examined the phenomena, comparing the “partial renewal case”, a combination method in question with the “whole renewal case”, a hypothetical combination method. And we also examined the “runs” in the combination processes. As the result, the properties and generating mechanism of the phenomena were clarified.
