INVENTORY CLASS (ABC) - An inventory control approach that segments inventory into ABC classes based on characteristics such as unit volumes, sales revenue or profit contribution. In the main, ‘A’ items tend to have the highest value within the categorisation used and often receive the most management attention. ‘B’ items represent the middle tier value and receive the next management attention, with ‘C’ items receiving the least management attention as the lowest value within the category measure used. The primary aim of ABC classification is to segment inventory based on priority and management by exception.

It seeks to determine the cost-optimal mix of rotables, repairables and spares to deliver maximum asset availability (e.g. aircraft, power generator) for a given budget. Conceptually, this technique shares some similarities with MEO and SLO but the mathematical approaches are different given the unique characteristics of MRO environments (e.g. very slow moving items, repair cycle turnaround time, etc).

The value of N, the number of periods to use for the average, reflects responsiveness versus stability in the same way that the choice of smoothing constant does in exponential smoothing.

PLANNING WEEK/PLANNING PERIOD - Measure of time (eg week, period, etc.) for which inventory activities are either planned (in the case of replenishment orders, excess stock, forecast adjustments) or expected to occur (in the case of forecast demand); any one of the next 52 rolling weeks or periods; designated by a unique number representing both the year and the sequential week number within the year.
PRE-BUILD INVENTORY - Inventory to be accumulated prior to forecasted depletions due to projected replenishment or production constraints (eg machine and labour capacity restrictions) or production levelling; pre-planned stock build-up for those items having future capacity restrictions.
PRICE/EARNINGS RATIO (P/E) - A valuation ratio of a company's current share price compared to its per-share earnings.
For example, if a company is currently trading at $43 a share and earnings over the last 12 months were $1.95 per share, the P/E ratio for the stock would be 22.05 ($43/$1.95). Earnings per share (EPS) is the portion of a company's profit allocated to each outstanding share of common stock and serves as an indicator of a company's profitability.

RETURN ON CAPITAL EMPLOYED (ROCE) - This ratio indicates the efficiency and profitability of a company's capital investments.
ROCE should always be higher than the rate at which the company borrows, otherwise any increase in borrowing will reduce shareholders' earnings. A variation of this ratio is return on average capital employed (ROACE), which takes the average of opening and closing capital employed for the time period.

Essentially, ROE reveals how much profit a company generates with the money shareholders have invested in it. Also known as return on net worth (RONW).
RETURN ON INVESTMENT (ROI) - A performance measure expressed as a percentage or ratio, used to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments.
If an investment does not have a positive ROI, or if there are other opportunities with a higher ROI, then the investment should not be undertaken.
RETURN ON NET ASSETS (RONA) - A measure of financial performance calculated as:
The higher the return, the better the profit performance for the company.

SERVICE FUNCTION - A mathematical relationship of the safety factor to service level, ie fraction of demand that is routinely met from stock.
SERVICE LEVEL - Percentage of demand (measured in dollars) for an item which is filled routinely from available stock; demand can come from internal (eg higher manufacturing processes) or external (eg customer) sources. One minus the service level equals the percentage of time an item's inventory can be expected to be out of stock.

TIME-PHASING - Process whereby period-specific inventory availability’s (on-hand, replenishment orders) are compared to period-specific inventory demands (unshipped demand, forecast demand, service stock) on a period-to-period basis to arrive at future inventory positions; where each period considers only those inventory factors specified for that particular period.
TLT - See TOTAL LEAD TIME.
TOTAL ANNUALISED COST - The total cost of replenishing an item's, or company's, inventory for a year.
TOTAL LEAD TIME (TLT) - Time in weeks required to replenish the item into inventory; composed of normal replenishment lead-time plus review time (usually one week).
