Q

What is Hierarchical planning?

A

The process that translates annual business plans & demand forecasts into a production plan for a product family (products that share similar characteristics) in a plant or facility leading to the Aggregate Production Plan (APP).

Q

What is a combination strategy?

A
  1. Produces at or close to full capacity for some part of the cycle
  2. Produces at a lower rate (or does not produce) during the rest of the cycle
  3. Makes use of available capacity, yet limits inventory buildup and inventory carrying costs
17
Q

What are the required external Inputs to the Production Planning System?

A 
Competitors’ behavior
Raw material availability
Market demand
Economic conditions
External capacity
18
Q

What are the required internal Inputs to the Production Planning System?

A

Current physical capacity
Current workforce
Inventory levels
Activities required for production

19
Q

What are costs associated with changing the production rate?

A

Hiring, training, layoffs, temps

20
Q

What are the costs associated with inventory holding costs?

A

Costs of capital, storage, insurance, taxes, spoilage, obsolescence

21
Q

What are the costs associated with Backordering costs?

A

Expediting, loss of goodwill, lost sales due to stocking out

22
Q

What costs are more associated with chase strategy?

A
  • Hiring and firing costs (chase)
  • Training costs (chase)
  • Subcontracting and Part-time labor costs (chase)
23
Q

What costs are more associated with level strategy?

A
  • Inventory-carrying costs (level)
  • Cost of stockout or back order (level)
  • Overtime and undertime costs (level)
24
Q

What is the master production strategy?

A

A detailed disaggregation of the aggregate production plan, listing the exact end items to be produced by a specific period.

25
Q

In MPS, Quantities represent__________, not what can be produced

A

what needs to be produced

26
Q

APP vs MSP

A

APP(Product Groups)

MPS(Specific End Items)

27
Q

What is the time-phased plan?

A

Specifying how many and when the firm plans to build each end item

28
Q

What is system nervousness?

A

Small changes in the upper-level-production plan cause major changes in the lower-level production plan

29
Q

Firms use a time fence to deal with nervousness by separating the planning horizon into:

A
  1. Firmed Segment(AKA demand time fence), from current period to several weeks into future. Can only be altered by senior management
  2. Tentative segment (AKA planning time fence), from end of firmed segment to several weeks into the future
30
Q

What is Material Requirements Planning?

A

Is the logic for determining the number of parts, components, and materials needed to produce a product.
