buildings or parts of buildings designated by US Secretary of the Treasury for storing imported merchandise. Operated by US Customs
buffer management
Theory of Constraints.
Process in which all expediting in a shop is driven by inventory quantity that is supposed to be kept in the buffers.
Expedites material into the buffers to prevent the constraint from being idle.
bullwhip effect
extreme change in supply position upstream caused by a small change in demand downstream.
business plan
Statement of long-range strategy.
Revenue, cost, and profit objectives accompanied by budgets, projected balance sheet and cash flow statements
capacity requirements planning (CRP)
Process of establishing, measuring, and adjusting limits or levels of capacity.
Determines in detail amount of labor and machine resources required to accomplish production tasks
cellular manufacturing
manufacturing process that produces families of parts within a single line (aka cell) of machines controlled by operators who work only within the line
centralized inventory control
Inventory decision making for all skus exercised from one office or department for an entire company
certified supplier
Status awarded to a supplier tha consistently meets predetermined quality, cost, delivery, financial, and count objectives.
Incoming inspection may not be required
chase production method
Goal is to produce the quantity demanded at any time. Inventory level is stable. Production adjusted to match sales requirements
closed-loop MRP
system built around MRP that also includes production planning, master production scheduling, and capacity requirements planning.
Also includes the feedback that is provided by the execution processes so that planning can be kept valid at all times.
consignment (2 definitions)
A shipment handled by a common carrier.
Also the process of a supplier placing goods at a customer location without receiving payment until after the goods are used or sold.
continuous flow production
Production system in which the productive equipment is organized and sequenced according to the steps involved in production.
Material flow is continuous during the production process.
Routing of jobs is fixed and setups seldom change.
continuous replenishment
Vendor-managed inventory
Supplier is notified daily of actual sales or warehouse shipments and commits to replenishing these without stock-outs and without replenishment orders.
control chart
Graphical comparison of process performance data with predetermined computed control limits.
Used to detect assignable causes of variation (not random variations).
control limit
Statistically determined line on a control chart. If value is outside this limit then process is deemed out of control.
cost of goods sold (COGS)
Accounting classification useful for determining amount of direct materials, direct labor, and allocated overhead associated with the products sold during a given period of time.
cost of poor quality – 4 cost categories
4 categories of cost.
1) Internal failure - found before customer receives the product.
2) External failure.
3) Appraisal costs - incurred to determine the degree of conformance to quality requirements.
4) Prevention cost.
critical chain method
AKA Critical Path Method (CPM)
In the theory of constraints this is a network planning technique for analyzing a project’s completion time.
Used for planning and controlling project activities.
Based on technological or resource constraints.
Tries to minimize or eliminate these
critical path method (CPM)
AKA Critical Chain Method
Network planning technique for analyzing a project’s completion time.
Shows each activity and the associated times in order to identify the constraint.
cumulative available-to-promise
Calculation based on the ATP figure in the master schedule.
= ATP from the previous period + the MPS of the period - the backlog of the period - the sum of the differences between the backlogs and MPSs of all future periods.
customer relationship management (CRM)
The collection and analysis of information designed for sales and marketing decision support. To understand and support existing and potential customer needs.
It includes account management, catalog and order entry, payment processing, credit and adjustments, and other functions
cycle stock
One of the two main conceptual components of any item inventory.
Cycle stock depletes gradually as customer orders are received. It is replenished cyclically when supplier orders are received.
