33
Q

Capacity

A

Ability to produce goods+services, in the long term>capacity generally fixed, in the short term> capacity can be altered.

Can be altered by OT, H/F, Extra Shift, Subcontracting

34
Q

Production planning Strategies

A

Chase, Level, subcontracting, and Hybrid plans.

35
Q

Chase

A
  • Production “chases” demand
  • Capacity fluctuations can be expensive
  • Inventory = 0, inventory investment is low.
  • Goods are made when demand occurs and are not stockpiled.
  • Costs related to carrying inventory are avoided, which can be very high.
36
Q

Level

A
  • Level output rate
  • Level workforce
  • Inventory investment is high
  • Capacity fluctuations costs are low
37
Q

Subcontracting

A
  • Produce at the level of forecasted demand
  • Excess demand> buying extra to meet demand or turning away demand+increasing prices
  • minimize costs of XS capacity+changes in production levels
  • Costs of purchasing > costs to make
  • Quantitative (Costs) and Qualitative concerns (workforce, quality, and core competency)
38
Q

MTS, level output

A

TPR= total 4cast(Total Demand)+EI-BI
Per production per period= TPR/# of periods
EI=BI+production-demand

39
Q

MTO

A
  • Backlogs only occurred in MTO
  • Backlogs are a pool of customer orders which we haven’t released to the production floor yet.
  • (Backlog= Beg.back+forecast(demand)-Prod.)
  • Backlog is work that is undone
  • Not inventory costs rather backlog costs/concerns
  • (Total 4cast+beg. backlog-end backlog)
  • (Projected Backlog=beg back log+ 4cast-prodn)
40
Q

Resource Bill

A

Shows quantity of critical resources(materials, labor, Bottleneck operations.

41
Q

Bottleneck

A

Anything that limits or constraints the output of a system

42
Q

Master production schedule (MPS)

A
  • Priority plan for MFg.
  • Must sum up to Sales and operations
  • Timing and sizing of individual end items.
43
Q

Rough-Cut Capacity Planning (RCCP)

A
  • Measures capacity in MPS
  • Resource bills
  • What were planning to produce under capacity limit.
  • Check for critical items
44
Q

Critical path

A

Longest path through Bill of material

45
Q

46
Q

MPS and MRP

Are lead time driven

47
Q

Available to promise (ATP)

A

Portion of a firms inventory and planned production that is not already committed to a specific customer order

48
Q

Final assembly schedule (FAS)

A

Actual build schedule, exact end item definitions. Last possible adjustment to MPS, so do it as late as possible. Any unsold items on the FAS will go into FG inventory.

49
Q

MPS Quantity (MPS Receipt)

A

is completed production that is planned to keep projected available > than zero or >some trigger point.(Safety Stock)

50
Q

A

Only changes from the top MGT are allowed, also a period of stability.

51
Q

A
  • Done by information system
  • Need to know where the records come from
