It has been proved that the first member of the hierarchy of the Kirkwood-Born-Green integro-differential equations which give the relation among the distribution functions of the polymer chain with excluded volume is equivalent to the Reiss variational method. Given that the joint probability density function of a polymer chain fulfils the super-position closure approximation then the first member of the Kirkwood-Born-Green hierarchy is shown to be equivalent to the Edwards method of the self-consistent field.
