5) = 4, and also the reciprocatory of anticipated performance is 1/4. The anticipated reciprocatory of efficiency is E [ 1/P] = (0. 5)/ 6 + (0. 5)/ 2 = 1/3. The reciprocal of anticipated productivity is 25% less than the anticipated value of the mutual in this case! By representing just two feasible productivity worths, this instance represents a severe case, yet it is always real that making use of ordinary efficiency consider Equation (9.

The usage of real averages for the reciprocals of efficiency or little adjustment aspects might be used to deal with for this non-linearity problem.
