What are the ordering methods of standing parts

Standing parts refers to the frequent use, equipment downtime loss and low unit price, often need to maintain a certain amount of reserve parts. Standing parts of the ordering method can be divided into three kinds:

1, ordering point method (quantitative ordering method): when the inventory falls to a certain amount (known as the ordering point), the missing number of supplemental orders issued. This way requires less money, can be used for lower overhead maintenance materials and small parts. If you use this method, as long as you do not miss the period of time to reach the order point can be, and therefore usually do not need to inspect the staff;

2, regular ordering method: every other period of time for ordering, but each time the order, according to the current inventory, the number of ordered but not yet arrived, as well as the forecast of the consumption of the calculation of the amount of the order. The advantage of this approach is that the ordering point for precision consumption forecasts, accounting for most of the amount of spare parts consumption, a few varieties of high-priced products, effective;

3, one by one to supplement the ordering method: modular products, maintenance is the replacement of the module, the failure of the unit for a qualified product, to be repaired after the failure of the unit (failure of the unit is often to be away from the machine for repair) and then arrange for the use of the unit. These spare parts are for on-site maintenance, there should be a certain amount of reserves, but should minimize its inventory, so take one after the use of an order a way. This is the so-called supplemental ordering method one by one.
