Sk. Goyal, DETERMINING ECONOMIC REPLENISHMENT INTERVALS FOR LINEAR TREND IN DEMAND, International journal of production economics, 34(1), 1994, pp. 115-117
In this note a simple method is given for determining economic repleni
shments of an item having linear trend in demand. The method requires
solution of only one cubic equation for the first replenishment. Each
subsequent replenishment interval requires solution of a quadratic equ
ation. An example is given to illustrate the method.
