Inventory Management
Inventory = the accumulation of transformed resources as they flow through processes, operations, or supply networks (Water Tank Analogy)
Physical Inventory: the accumulation of physical materials such as components, parts, finished goods or physical (paper) information records
Queues: the accumulation of customers, be they physical (people in an airport departure lounge) or virtual (waiting for services on a phone)
Databases: the accumulation of digital information, such as medical records or insurance details

The time interval
The interval between placing orders, t1, is usually calculated on a deterministic basis, and derived from the EOQ
Therefore, EOQ= √(2CoD / Ch)

Controlling inventory
ABC system
-
Generally, a relatively small proportion of the total range of items contained in an inventory will account for a large proportion of the total usage value (Pareto Law)
Types of classes
Type A
20% or so of high, usage-value items that account for around 80% of the total usage value
Type B
medium usage value, usually the next 30% of items, which often account for around 10% of the total usage value
Type C
low usage value items that, although comprising around 50% of the total types of items stocked, accounts for around 10% of the total usage value of the operation
-
more complex stock classification systems might include these criteria by classifying on an ABC basis for each (A/B/A)
