In the current system, there problem symptoms on each step of supply chain, such as for certain products there is no enough inventory, for the rest there is excessive inventory, also there is excessive finished goods inventory, in addition lack of providing finished goods to the customer on time, and incorrect forecast that does not match with actual demand.
