Question | Answer |
---|---|
Replanning frequency | In an MRP system, the amount of time between successive runs of the MRP model. If the planner does not run MRP frequently enough, the material plan becomes inaccurate and MatReq and inventStatus change with the passage of time |
Requisition | An authorization that identifies the item and quantity required to be withdrawn from an inventory |
Rescheduling | The process of changing order or operation due dates, usually as a result of their being out of phase with when they are needed. |
Rework | Reprocessing to salvage a defective item or part |
Risk pooling | A method often associated with the management of inventory risk. Manufacturers and retailers that experience high variability in demnd for their products can pool together commn invent cmpnts associated with a broad fam of prod to buffer the overal burden |
Safety capacity | In TOC, the planned amnt by which the avil cap exceeds curr productive cap. Safety capacity+productive capacity+excess capacity = 100% capacity |
Safety lead time | An element of time added to nrml LT to prot against fluctutation in LT so that an ordr can be compltd b4 its real need date. When used, the MRP system, in offsetting for LT, will plan both ordr release and ordr completion for earlier dates thn it would. |
Scheduled load | A std hrs of wrk required by scheduled receipts |
Semifinished goods | Products that have been stored uncompleted waiting final operations that adapt them to different uses or customer specification. |
Shelf life | The amt of time an item may be held in inventory b4 it becomes |
Shrinkage | Reduction of actual qtys of items in stock, in process, or in transit. The loss may be caused by scrap, theft, deterioration, evaporation, and so forth |
Standard deviation | A measurement of dispersion of data or of a variable. The std dev is cpputed by finding the diff btw the avg and actal observations, squaring each dff, adding the sqrd diff, dividing by n-1(for a sample), and taking the sqrt of the result. |
Supplier measurement | The act of measuring the supplier's performance to a contract. Measurements usually cover delivery reliability, LT, and price. |
Target inventory level | In a min-max inventory system, the equivalent of the maximum. The target inventory is equal to the order point+a variable order qty. It is often called an order-up-to inventory level and is used in a periodic review system. |
Theoretical capacity | The max output capability, allowing no adjustments for preventive maintenance, unplanned downtime, shutdown, and so forth. |
Third-party logistics (3PL) | A buyer and supplier team with a third party that provides product delivery services. This third party may provide added supply chain expertise. |
Transient state | In waiting line models, early behavior of a characteristic of the model, such as line lengths, is more erratic than eventual performance of the line. Data are usually not collected from the model until less erratic behavior emerges. |
Unplanned repair | Repair and replacement requirements that are unknown until remanufacturing teardown and inspection |
Safety capacity planned and unplanned activities | This cap provides prot frm planned activities such as resource contention, and preventitive maintenance and unplanned activities, such as resource breakdown, poor Q, rework,or lateness |
responsible procurement | Assuring the use of ethical sources of goods and services to bring about a positive impact and minimize the negative impact on societies and environments, including reduce, reuse, and recycle of materials, where a firm does business |
specific identification | This method keeps track of the units of the beginning inventory and the units purchased - that is, specific identification of the purchase cost of each item. This may be done through a coding method or serial number identification. |
vertical dependency | The relationship between a parent item and a component in its bill of material that defines the need for the component based on producing the parent, without regard to the availability of other components at the same level in the bill of material |
