Additional Management Flashcards

 


 

Cards

Term
Sales and operation planning (S&OP)-
Definition

balances resources and forecasted demand and aligns the organizations competing demands, from supply chain to final customer while linking strategic planning with operations over all planning horizons

Term
Aggregate planning-
Definition

 an approach to determine the quantity and timing of production for the intermediate future(usually 3 to 18 months ahead)

Term
Disaggregation
Definition

– the process of breaking an aggregate plan into greater detail

Term
Master production schedule
Definition

a timetable that specifies what is to be made and when.

Term
Chase strategy-
Definition

 a planning strategy that sets production equal to forecast demand.

Term
Level scheduling
Definition

 –maintaining a constant output rate, production rate, or workforce level over the planning horizon,

Term
Mixed strategy
Definition

– a planning strategy that uses two or more controllable variables to set a feasible production plan.

Term
Graphical techniques
Definition

 –aggregate planning techniques that work with a few variables at a time to allow planners to compare projects demand with existing capacity.

Term
Transportation method of linear programming
Definition

–a way of solving for the optimal solution to an aggregate planning problem .

Term
Revenue(or yield ) management-
Definition

- capacity decisions that  determine  the allocation of resources to maximize revenue

Term
Material requirements planning (MRP)
Definition

a dependent demand technique that uses a bill of material inventory expected receipts and master production schedule to determine material requirements .

Term
Master production schedule(MPS)
Definition

 a timetable that specified what is to be made and when.

Term
Bill of material (BOM)
Definition

 a listing of the components their description  the quantity of each required to make one  unit of a  product.

Term
Modular bills
Definition

– bills of material organized by major subassemblies of by products options

Term
Planning bills ( or kits)
Definition

 a material grouping created in order to assign an artificial parent to a bill of material; also called pseudo bills

Term
Phantom bills of material
Definition

 – bills of material for components usually subassemblies that exist only temporarily they are never  inventoried

 

Term
Low-level coding
Definition

 – a number that identifies items at the lowest level at which they occur

Term
Lead time-
Definition

 in purchasing systems that time between recognition of the need for an order and receiving it; in production systems it is the order , wait, move, queues , setup and run times for each component .

Term
Gross material requirements plans-
Definition

a schedule that shows the total demand for an item (prior to subtraction of an hand inventory and scheduled receipts and (1) when it must be order from suppliers , or (2) when production must be stated to meet its demand by a particular date

Term
Net material requirements
Definition

 – the result of adjusting gross requirements for inventory on hand and scheduled receipts

Term
Planned order receipt-
Definition

Planned order receipt- the quantity planned to be received at a future date

Term
Planned order release-
Definition

 the scheduled date for an order to be released

Term
System nervousness
Definition

 -  frequent changes in an MRS system

Term
Time fences- a means
Definition

 for allowing a segments of the master schedule to be designated as not  to  be rescheduled. 

Term
Pegging
Definition

–in material requirement planning systems tracing upward the bill of material from the component to the parent item

Term
Buckets-
Definition

 time units in a material requirements planning system

Term
Lot- sizing decisions
Definition

– the process of or techniques used in determining lot size

Term
Lot- for lot
Definition

- a lot-sizing a lot sixing techniques that generates exactly what is required to meet the plan

Term
Periodic order quantity(POQ)
Definition

 a lot sixing technique that issues order on a predetermined time interval with an order quantity equal to all of the intervals requirements

Term
Material requirements planning ii-(MRPii)
Definition

  system that allow with MRP in place inventory data to be augmented by other resources variables in this case MRP becomes material resource planning

Term
Closed loop MRP system
Definition

- a system that provides feedback to the capacity plan master production schedules and production plan so planning can be kept valid at all times

Term
Load report
Definition

-a report for  showing the resource requirements in a work center for all work currently assigned there as well as all planned and expected orders

Term
Distribution resource planning  (DRP)
Definition

 a timed phased stock replenishment plan  for all levels for a distribution   network

Term
Enterprise resource planning (ERP)
Definition

 an informational system for identifying and planning enterprise wide resources needed to take  make ship and account for customer orders

Term
Efficient consumer response (ECR)
Definition

 supply-chain management systems in the grocery industry that ties sales to buying to inventory to logistics and to production

Term
Input-output control –
Definition

 A s system that allows operation personnel to manage facility work flows by tracking work added to a work center and its work completed

Term
Con WIP cards
Definition

- cards that control the amount of work in a work center, aiding input/output control

Term
Gantt charts-
Definition

 planning charts used to schedule resources an allocate time

Term
Assignment method
Definition

– a special class o linear programming models that involves assigning tasks or jobs to resources

Term
Sequencing
Definition

 – determining the order in which jobs should be done  at each work  center

Term
 Priority rules-
Definition

 rules used to determine the sequences of jobs in process-oriented facilities.

Term
Flow times-
Definition

 times each job spends waiting plus the times being processed

Term
Critical ratio (CR)
Definition

 -a sequencing rule that is an index number computed by deciding the time remaining until due dates by the work time remaining

Term
Johnson’s rule-
Definition

an approach that minimizes processing time for sequencing a group of jobs through two work centers while minimizing total idle time in the work centers

Term
Finite capacity scheduling (FCS)
Definition

- computerized short-term scheduling that overcomes the disadvantage of rule-base system by providing the user with graphical interactive computing.
