Multi echelon Inventory Management for four stations 

Sir, as said by you, value of the product increases towards right, the holding cost should also increase towards right. There is a mistake of the sign, it should be h1 < h2 < h3 < h4 (ignoring the equality) instead of h1 > h2 > h3 > h4 (ignoring the equality).

Nice explanation sir, but i think in starting ,the sign of holding cost you took in wrong direction.
