ABSTRACT
In order to obtain an optimum result of standardization, many scholars have performed extensive study on the method of setting or revising standard scientifically and given mathematical programming methods such as functioncost method, minimum cost method, least life period method, etc., Shen Jingning (1983), for the optimisation of parameter of the standardization object. The objective functions of these methods are respectively expressed in the form of currency directly or indirectly, therefore, a common shortcoming exists in these methods, i.e. all the mathematical models of the standardization objects do not reflect on the uncertain factors that effect the optimum result of standardization
such as some factors concerned with sociology, psychology, etc. which cannot be expressed in the form of currency.
