An eclectic approach for replenishment with non-linear decreasing demand

Following the pattern of our previous work, which has dealt with linear increasing and decreasing demand and non-linear increasing demand, a parametric eclectic model has been developed for a non-linearly decreasing demand pattern. Alternative replenishment plans can be generated if the parameter vector is adjusted within a certain range. Using the eclectic approach the best result is chosen. For 12 examples, calculations based on three established heuristics, Silver's method, CLUC, and CTPP produced an average percentage increase in cost above that of our eclectic heuristic algorithm of 4.8%, 3.4% and 3.2% respectively.
