18-0464: Consider an elementary inventory control system where there is no delay between the ordering of goods and their receipt into inventory. Suppose the order rate is directly proportional to the difference between desired inventory and actual inventory, with proportionality constant 1/A. where A is the time that would be required to correct the inventory if the order rate were constant. Write a FORTRAN program to simulate this system, using modified Euler's method (the method is fully explained, and the subroutine for it is given in the SIMULATION chapter) from time t=0 to t=t if I() is the inventory level at time t and I(0=10- s I I(t) INVERT SIGN -I (VA) 11
