Once you have your suppliers, batch tracking ensures your stock consistently meets your highest quality standards. Even with EOQ and reorder points set, anticipating future demand is notoriously difficult.

To avoid obsolescence and spoilage, inventory forecasting must be utilized to keep inventory levels low yet adequate to match customer demands. Even big players fall victim to improper inventory forecasting.

Basic Concepts in Inventory Management 2 Abstract In this chapter, the concept of inventory is discussed which is central to materials management function. The definition of inventory and various types of inventories — raw materials, finished goods, in-process inventory, MRO inven- tory, etc. The need to keep inventory and the functions of inventory as a decoupling agent to enable various subsystems in a supply chain to be decoupled are described. The inventory-related cost parameters are listed along with methods of estimating these.

Other situational parameters like demand and lead times also need to be estimated. Before an inventory model is employed for optimal operation of the inventory system, an appropriate inven- tory policy has to be selected.

Three types of inventory policies are described, and their relative strengths and weaknesses are discussed.

A taxonomy of inventory models is presented to give an overview of a plethora of inventory models available in inventory management literature. However, the right choice of the inventory model is crucial for the success of inventory management. Inventory or stock in common terms is considered to be the central theme in managing materials.

The inventory turnover ratio ITR is a barometer of performance of materials management function. In the generally understood term, inventory means a physical stock of goods kept in store to meet the anticipated demand. Thus, the paradox is that we need inventory, but it is not desirable to have inventory.

It is this paradoxical situation that makes inventory management a challenging problem area in materials management. It also makes a high inventory turnover ratio as a desirable performance indicator.

These include the following: a Raw materials inventory as input to manufacturing system. From the resource management point of view, we should not have inventories as these constitute the idle resources. However, if we did not have inventories, there will be shortages, production delays, and project delays. Time lag between placing orders and getting supplies at the point of consump- tion — Whenever we place a replenishment order, there is a time lag between placing the order and getting the materials at the point of use.

This necessitates holding of inventory to take care of demand during the lead times. Inventory has to be maintained as a shield to cope with the supply uncertainty.

If there was no such uncertainty and if demand and supply are deterministic, then in just-in-time JIT -type environment, no or low inventory will be required. The greater the amount of supply uncertainty, the greater the amount of additional inventory required. Demand variability — If either we are unable to estimate the demand correctly or if there are uncertainties in demand, additional inventory will be required to act as a shield to absorb the demand variability.

The greater the demand variability, the greater the amount of additional inventory required. Seasonal inventory — If the demand is cyclic or seasonal, then sometimes building inventory in the lean period to meet the peak period demand is employed as a strategy in aggregate production planning. This strategy results in inventory in some part of the year. This constitutes the pipeline inventory.
