Module 1 - G Flashcards
ABC classification
The classification of a group of items in decreasing order of annual dollar volume (price multiplied by projected volume) or other criteria. This array is then split into three classes, called A, B, and C. The A group usually represents 10 percent to 20 percent by number of items and 50 percent to 70 percent by projected dollar volume. The next grouping, B, usually represents about 20 percent of the items and about 20 percent of the dollar volume. The C class contains 60 percent to 70 percent of the items and represents about 10 percent to 30 percent of the dollar volume. The ABC principle states that effort and money can be saved through applying looser controls to the low-dollar-volume class items than to the high-dollar-volume class items. The ABC principle is applicable to inventories, purchasing, and sales.
anticipation inventories
Additional inventory above basic pipeline stock to cover projected trends of increasing sales, planned sales promotion programs, seasonal fluctuations, plant shutdowns, and vacations.
average inventory
One-half the average lot size plus the safety stock, when demand and lot sizes are expected to be relatively uniform over time. The average can be calculated as an average of several inventory observations taken over several historical time periods; for example, 12-month ending inventories may be averaged. When demand and lot sizes are not uniform, the stock level versus time can be graphed to determine the average
backflush
A method of inventory bookkeeping where the book (computer) inventory of components is automatically reduced by the computer after completion of activity on the component’s upper-level parent item based on what should have been used as specified on the bill of material and allocation records. This approach has the disadvantage of a built-in differential between the book record and what is physically in stock.
balance sheet
A financial statement showing the resources owned, the debts owed, and the owner’s share of a company at a given point in time.
carrying cost
The cost of holding inventory, usually defined as a percentage of the dollar value of inventory per unit of time (generally one year). This depends mainly on the cost of capital invested as well as costs of maintaining the inventory such as taxes and insurance, obsolescence, spoilage, and space occupied. Such costs vary from 10 percent to 35 percent annually, depending on type of industry. This is ultimately a policy variable reflecting the opportunity cost of alternative uses for funds invested in inventory.
cash flow
The net flow of dollars into or out of the proposed project. The algebraic sum, in any time period, of all cash receipts, expenses, and investments. Also called cash proceeds or cash generated.
cost of goods sold (COGS)
An accounting classification useful for determining the amount of direct materials, direct labor, and allocated overhead associated with the products sold during a given period of time.
cycle counting
An inventory accuracy audit technique where inventory is counted on a cyclic schedule rather than once a year. A count is usually taken on a regular, defined basis (often more frequently for high-value or fast-moving items and less frequently for low-value or slow-moving items). Most effective systems require the counting of a certain number of items every workday with each item counted at a prescribed frequency. The key purpose of this process is to identify items in error, thus triggering research, identification, and elimination of the cause of the errors.
cycle stock
One of the two main conceptual components of any item inventory, this is the most active component. This depletes gradually as customer orders are received and is replenished cyclically when supplier orders are received. The other conceptual component of the item inventory is the safety stock, which is a cushion of protection against uncertainty in the demand or in the replenishment lead time.
days of supply
1) Inventory-on-hand metric converted from units to how long the units will last. For example, if there are 2,000 units on hand and the company is using 200 per day, then there are 10 days of supply. 2) A financial measure of the value of all inventory in the supply chain divided by the average daily cost of goods sold rate.
decoupling inventory
An amount of inventory maintained between entities in a manufacturing or distribution network to create independence between processes or entities. The objective of decoupling inventory is to disconnect the rate of use from the rate of supply of the item.
direct labor
Labor that is specifically applied to the good being manufactured or used in the performance of the service.
direct material
Material that becomes a part of the final product in measurable quantities.
distribution inventory
Inventory, usually spare parts and finished goods, located in the distribution system (e.g., in warehouses or in transit between warehouses and the consumer).
economic order quantity (EOQ)
A type of fixed order quantity model that determines the amount of an item to be purchased or manufactured at one time. The intent is to minimize the combined costs of acquiring and carrying inventory. The basic formula is:
where A = annual usage in units, S = ordering costs in dollars, i = annual inventory carrying cost rate as a decimal, and C = unit cost.
finished goods inventory
Those items on which all manufacturing operations, including final test, have been completed. These products are available for shipment to the customer as either end items or repair parts.
fixed order quantity
A lot-sizing technique in MRP or inventory management that will always cause planned or actual orders to be generated for a predetermined fixed quantity, or multiples thereof, if net requirements for the period exceed the fixed order quantity.
fixed overhead
Traditionally, all manufacturing costs—other than direct labor and direct materials—that continue even if products are not produced. Although fixed overhead is necessary to produce the product, it cannot be directly traced to the final product.
fixed reorder cycle inventory model
A form of independent demand management model in which an order is placed every n time units. The order quantity is variable and essentially replaces the items consumed during the current time period. If M is the maximum inventory desired at any time and x is the quantity on hand at the time the order is placed, then in the simplest model, the order quantity equals M minus x. The quantity M must be large enough to cover the maximum expected demand during the lead time plus a review interval. The order quantity model becomes more complicated whenever the replenishment lead time exceeds the review interval, because outstanding orders then have to be factored into the equation.
fluctuation inventory
Inventory that is carried as a cushion to protect against forecast error.
general and administrative expenses (G&A)
The category of expenses on an income statement that includes the costs of general managers, computer systems, research and development, etc.
generally accepted accounting principles (GAAP)
Accounting practices that conform to conventions, rules, and procedures that are generally accepted by the accounting profession.
gross margin
The difference between total revenue and the cost of goods sold.
