Abstract

Step 2 in Wu and Ouyang's [I] algorithm given on page 558 provides the condition to determine the optimal integral value of the decision variable n. I do not realize why Chung [2] makes such a statement on page 276 as "They appear to take it for granted that one of the closest integers to n° is the optimum value, when n isforced to be an integer". I think that Wu and Ouyang's algorithm is perfect and hence it is entirely unnecessary that Chung uses calculus to yield equation (6) to examine the functional behavior ofthe joint annual total relevant cost function with respect to n. In addition, the four comments made in this note show that there is some room for improvement in relation to algebraically solving Wu and Ouyang's model so that the pedagogical advantages of model solution and problem evaluation are more eminent. © 2009 IEEE.
