A method is provided for extending a sequence repetition period of a random number generator in systems based on the availability of random sequences. The method includes performing RNS arithmetic operations to express a random number in a sequence as RNS residue values. Each generated random number has a value between zero and n!−1. The method also includes converting each of the RNS residue values to a relatively prime base number system so that each of the RNS residue values includes at least one digit. The method further includes generating an arbitrary permutation ordering of output sequence numbers using a select combination of digits associated with each of the RNS residue values. The arbitrary permutation ordering is applied to a cyclic structure having n elements. Each of the n elements has an associated output sequence number.

A computing device provides a random number table. Formulas for calculating size differences between a first object and a second object are written to the random number table. The random number table is controlled to select random samples which are taken as an actual size of the first object and an actual size of the second object. According to a user's requirement, the random samples are selected many times. The computing device obtains an absolute value of size difference which is the most in the random number table. All actual maximum differences and all actual minimum differences corresponding to the obtained absolute value of size difference are obtained. The computing device selects a maximum value of the all actual maximum differences and a minimum value of the all actual minimum differences as a standard for manufacturing the first object and the second object.
