Q

When can a periodic review replenishment method best be used?

A
  • The goal is to lower ordering costs

Q

In order to use the EOQ method for replenishment four assumptions have to apply, which ones are these?

A
  • Demand is constant

Q

What does the itemized inventory policy do?

A

It provides constraints on the upper and lower limits of an items inventory amount.

  • Upper limit controls costs
  • Lower limit controls stockout costs

Q

In what four types of situations is L4L used?

A
  • In planning and fulfilling time-phased requirements for dependent demand items in MRP and for independent demand items in MPS
  • When ordering or making inexpensive or infrequently used items
  • When ordering perishable items where there is the risk of loss due to expired shelf life
  • In lean, to reduce waste

Q

There are five factors that determine the amount of safety stock, which five are these?

A
  • The degree of variability in demand
  • Forecast error
  • Order frequency
  • Service level
  • Lead time
20
Q

The first step of the statistical method approach to calculating safety stock is to calculate the degree to which demand can be expected to fluctuate. In what three ways can this be done for the different methods?

A
  • Standard deviation of actual demand from average demand
  • Root mean squared error (RMSE) of actual demand from forecast demand
  • Mean absolute deviation (MAD) of actual demand from forecast demand
21
Q

What is the difference between using SD vs RMSE for calculating safety stock?

A

SD measures the volatility of demand but does not address the reliability of the forecast. RMSE was developed to account for forecast reliability

22
Q

What is time period safety stock?

A

It provides an even amount of safety stock, equal to the estimated usage over a designated time frame. The safety stock varies with change in demand

23
Q

When is the fixed order safety stock used?

A

When to plan safety stock quantities for parts that require special oversight. For example when transitioning in and out of use

24
Q

What are maintenance, repair and overhaul items?

A

Items for reprocessing in the manufacturing industry

25
Q

What is mean time between failures (MTBF)?

A

The average time interval between failures for repairable products for a defined unit of measure

26
Q

What is mean time to failure (MTTF)?

A

The average time for failure of a nonrepairable product (expected life) or average time to first failure of a repairable product

27
Q

What is mean time to repair (MTTR)?

A

The average time that it takes to repair a product

28
Q

What three costs are included in carrying costs?

A
  • Capital costs
  • Storage costs
  • Risk costs
29
Q

What is landed costs?

A

The product cost + the cost of logistics, such as warehousing, transportation, and handling fees

30
Q

Total costs are the sum of which three costs?

A
  • Carrying costs
  • Ordering costs
  • Stockout costs
31
Q

What is risk pooling?

A

A method associated with the management of inventory risk. In risk pooling an organization centralizes its inventory. Demand from various sources is aggregated, so reduced variability in demand and improved forecasting

32
Q

Inventory is often grouped in storage based on certain principles, which four are these?

A
  • Items are functionally related
  • Fast-moving items are stored together
  • Items with similar storage needs are stored together
  • Working stock and reverse stock are separated
33
Q

Tasks associated with managing inventory responsibility and control by suppliers can be done in four forms, which are these?

A
  • Rapid replenishment strategies
  • Continuous replenishment strategies
  • Vendor-managed inventory (VMI) strategies
  • Consignment
34
Q

What entails a rapid replenishment strategy?

A

Data from the customer (point of sale or orders) are used to align supplier’s production schedule. Customer still makes orders

35
Q

What entails a continuous replenishment strategy?

A

The supplier assumes responsibility for tracking customers inventory levels and replenishing items in a way that meets agreed service levels but without customer orders

36
Q

What is a vendor managed inventory strategy?

A

The supplier performs some of the tasks associated with the itemized inventory policy. Customer has to share data on demand. Vendor assumes responsibility.

37
Q

What is a consignment strategy?

A

A vendor holds inventory at the supplier location and only charges at use

38
Q

What are the three levels of traceability? from high level to low level.

A
  • Class
  • Batch/lot
  • Instance
39
Q

What are the four purposes that a ASN serves?

A
  • It provides a time for arrival
  • It allows consignee time to arrange delivery appointment
  • It enables the consignee to redeploy the shipments contents
  • Can reduce uncertainty in order replenishment
40
Q

What are the six steps in the waste hierarchy from most sustainable -> least sustainable?

A
  1. Avoid
  2. Reduce
  3. Reuse
  4. Recycle
  5. Recover
  6. Dispose
41
Q

What is the Kobe 3R action plan?

A

A plan from environment ministers from G8 countries to decouple resource consumption and environment degradation associated with economical activities. It stands for Reduce, reuse, recycle

42
Q

What is the total cost of ownership in supply chain?

A

The sum of all the costs associated with every activity of the supply chain

43
Q

What are the four steps of the reverse logistics process?

A

Step 1. The product is retrieved

Step 2. The product is transported to a receiving center

Step 3. The product is logged in, inspected and sorted

Step 4. The product is handled according to disposition protocol

44
Q

What is a material review board (MRB)?

A

A board or committee that sets the policy regarding disposition and determines the resolution or disposition of items that have questionable quality or other attributes

45
Q

What are the six ways a dispositioned item can be handeld?

A
  • Return to stock
  • Return to manufacturer
  • Liquidate
  • Donate
  • Recycle
  • Dispose
46
Q

What are the four costs included in product disposition?

A
  • Return goods handling
  • Returns inventory costs
  • Return processing costs
  • Return disposal costs
