its completion

neither to high nor to low level of inventory is beneficial
there is no cut- and – dried formula to estimate or predict demand
there is no thumb rule to forecast demand
thrilling pressure to cut down there total logistical cost especially inventory

If company holds high level inventory, it may be capable enough to meet
unforeseen demand and generate additional sales, volumes due to advantages of impulse buying tendencies,
but at the same time it leads to undue: Carrying/ holding charges in form of taxes,
insurance, storage facilities, depreciation. Involvement of working capital which ultimately
affects the overall profitability of the firm.

Inventory is essential for smooth functioning of any organization mainly due to geographical specialization , periodic variation and for balancing of supply and demand.
Given limited resources firms must often choose among alternative investment decisions example between focusing on reducing demand fluctuations, lead times or lead time fluctuations.

Traditionally proper management of inventory levels to issues need proper attention and analysis:
1 .Order quantity(How much to order of each material with either outside supplier or production department within organization. It is also called LOT Sizes or Economic Order Quantity,EOQ)
2. Order Points (When to place the orders. It is also called Reorder Points,RP)

Techniques like JIT, MRP , DRP etc to cut down there total logistical cost
EDI, DND, ERP, Bar coding, intranet,
extranet, internet to reduce inventory level without stock out situation

SummaryInventory levels are affected by customer service expectations, demand uncertainty, and , the flexibility of the supply chain
For products with high uncertainty in demand , a more responsive supply chain and larger buffer inventories may be needed to meet a desired customer service level
