3D Printing - 3D printing is a process by which a three-dimensional component is ‘printed’ from its raw materials, layer-by-layer. The technology has evolved significantly in recent years enabling printing of various alloys, metals and plastics using a variety of processes—including multi-material printing.

ABC Analysis - An inventory categorisation approach used to assign different groupings and service levels to items according to their importance, as defined by an organisation specific criteria (often sales). ABC analysis typically divides inventory into three (or more) categories; "A" class items, "B" class items and "C" class items. "A" items being an organisations most valuable and typically receiving the highest service level requirement, planning priority and effort. "C" items are typically an organisations least valuable items and are assigned lower service level requirements, and lesser planning priority. Typically the "A" items represent 10-20% of number of items, and 50-70% by projected dollar volume. The "B" items represent about 20% of the items and 20% of the dollar volume. The "C" items represent 60-70% of the items and approximately 10-30% of the dollar volume.

The difference between a cross-dock (C-D) network and traditional hub and spoke distribution is that in cross dock, there is no inventory held at the branch parent. The C-D location serves as a transit point and/or re-packaging facility only, at which material is received from the vendor, potentially re-packaged, and shipped out to branch locations where it is then stocked, typically within a day. A C-D design is particularly advantageous for companies who have high vendor minimums and/or high re-handling costs.

Crowd Shipping - A spectrum of delivery options ranging from linking smaller carriers together, to creating a delivery network from scratch, by aggregating individual drivers, riders or walkers.

CRP - See Continuous Replenishment Planning (CRP).

CSLO - Constrained Service Level Optimisation (CSLO) is a GAINS Advanced Planning System functionality which is similar to IDO in that it can determine the lowest-cost service level for SKULs, but it can also find other organisational targets such as the minimum inventory investment, greatest cash flow, or greatest profit.

Price/Earnings Ration (P/E) - A valuation ratio of a company's current share price compared to its per-share earnings. Where P/E Ratio = Market Value per Share/ Earnings per Share (EPS) 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).

Service Level Optimisation - SLO is a technique that determines the optimal service level policy for a given set of constraints.

Set-Up Cost - Fixed cost associated with manufacturing set-up operation to produce a replenishment quantity not a function generally of run size; synonymous with receiving cost when applied to a manufacturing environment; can be used in conjunction with (ie in addition to) receiving cost to portray total cost.

Shelf Life - Estimated length of time an item can remain in inventory under normal or specified conditions before its saleability, quality, etc. are affected.

Simulation - Modelling of real-world conditions and behaviour in order to compare the effectiveness of design procedures without the normal time and energy constraints.

SKU - See Stock Keeping Unit

SKUL - SKU by Location

Sporadic Demand - Demand showing a random or uncorrelated pattern over time; typically exhibiting lumpy demand characteristics where a majority of annual demand activity falls within several intervals of the year.

Standard Cost - Current replacement cost per unit of measure

Stock Keeping Unit (SKU) - Lowest level at which an inventory is measured and/or controlled; can be a raw material, purchased part, manufactured part, operating supply or finished good; synonymous with inventory item.

T

Third-Party Logistics (3PL) - Refers to providers of logistics related services performed on behalf of a manufacturer. Services might include storage of goods, processing of orders and packaging and distribution of inventory.

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).

Turnover, Actual - Historical index representing the number of times that an inventory (item or aggregate) cycles during the year; generally computed as historical annual demand or usage divided by the current inventory available. Typically, turnover is used as a measure of inventory performance.

Turnover, Forecast - See Forecast Stock Turnover

U

Unshipped Demand (Back Order) - See Back Order

V

Vendor-Managed Inventory (VMI) - The process of a vendor (supplier) managing the stock levels and purchases of the materials supplied.

Virtual Reality - A computer technology that uses Virtual reality headsets, sometimes in combination with physical spaces or multi-projected environments, to generate realistic images, sounds and other sensations that simulate a user's physical presence in a virtual or imaginary environment.

VR - See Virtual Reality

W

Warehouse Management System (WMS) - Software designed specifically for managing the movement and storage of materials throughout the warehouse to maximise the use of warehouse space.

Weight - Current weight per unit of measure.

Working Capital - A measure of both a company's efficiency and its short-term financial health. The Working Capital ratio is calculated as: Working Capital = Current Assets - Current Liabilities Positive working capital means a company is able to pay its short-term liabilities. Negative working capital means a company is unable to meet its short-term liabilities with its current assets (cash, accounts receivable and inventory).
