In addition to customer orders, the master production schedule (MPS) might handle which of the
following types of demand?
Bill-of-material items
Interplant orders
Dependent demand
Parts list items
Interplant orders: Interplant demand is usually handled by the master production scheduling system
in a manner similar to customer orders.
A shipment of remote control components is delivered to a factory and immediately taken to a
workstation ready to begin assembly. What is the name of this inventory management technique?
Lot-for-lot
Lot control
Efficient
Wall-to-wall inventory
Wall-to-wall inventory: In wall-to-wall inventory management, materials enter a plant and are
processed right away, as opposed to being logged in an inventory store until a later date.
Given the following, what is the work center backlog?
Average input: 100 units/week
Average output: 100 units/week
Current work in process: 160 units
.63 weeks
1 week
1.6 weeks
2.6 weeks
1.6 weeks: To calculate the load that is backlog at a work center, divide the current number of units
(or hours) currently at the work center by the average output, or 160 units/100 units of output per
week = 1.6 weeks of load.
Which correctly identifies the following examples of costs as internal failure (I), external failure (E),
appraisal costs (A), and prevention costs (P)?
Operator training= I; product recalls and loss of customers = E; scrap and machine maintenance= A;
in-line inspection = P
Machine maintenance and in-line inspections = I; scrap and loss of customers = E; product recalls = A;
operator training = P
Scrap = I; product recalls and loss of customers = E; in-line inspections = A; machine maintenance and
operator training = P
Product recalls = I; scrap and in-line inspections = E; loss of customers =
Scrap = I; product recalls and loss of customers = E; in-line inspections = A; machine maintenance and
operator training = P: Scrap is an internal failure cost because it occurs without the customer seeing it.
Product recalls and loss of customers are external failure costs because the first is directly
experienced by customers and the second is a direct customer reaction to poor quality. In-line
inspections are an appraisal cost because this is an example of a quality control activity. Machine
maintenance and operator training are examples of prevention costs because these are investments
designed to reduce the chances of quality problems occurring in the first place.
Companies typically make final purchasing decisions based on which of the following supplier
characteristics?
Supplier fixed cost
, Product advertising
Delivery reliability
Free-on-board shipping
Delivery reliability: Besides perfect quality, a key final purchasing decision point is delivery reliability.
Ensuring that purchase deliveries arrive on time is an essential feature of supplier partnerships.
What type of demand inventory ordering model includes fixed reorder cycles, fixed reorder
quantities, optional replenishment, and hybrid models?
Material requirements planning
Independent
Drum-buffer-rope
Kanban
Independent: independent demand inventory ordering models include fixed reorder cycles, fixed
reorder quantities, optional replenishment, and hybrid models, among others. Dependent demand
inventory ordering models include material requirements planning, kanban, and drum-buffer-rope.
What is the primary difference between enterprise resources planning (ERP) and manufacturing
resource planning (MRP II)?
ERP is computer-based, but MRP II is not.
ERP integrates additional business functions, including human resources, research and development,
logistics, and others.
ERP includes manufacturing information only.
ERP provides a balance between production, marketing, and information technology.
ERP integrates additional business functions, including human resources, research and development,
logistics, and others.: ERP provides more than just manufacturing information; it integrates business
functions like human resources, research and development, and logistics. MRP II and ERP are both
computer-based, and both provide a balance between production, marketing, and information
technology.
The day 56 log for a work center shows planned input of 14 hours, actual input of 16 hours, and a
cumulative input variance of -2 hours. For the same day the planned output was 15 hours, the actual
output was 14 hours and the cumulative output variance was -5 hours. The day 55 log showed the
planned backlog was 7 hours and the actual backlog was 6 hours. What is the planned backlog for day
56?
0 hours
6 hours
-7 hours
8 hours
6 hours: Planned Backlog = Previous Planned Backlog + Planned Input - Planned Output = 7 hours + 14
hours - 15 hours = 6 hours.
For the past six months, a manufacturer has experienced monthly forecast deviations of 15, -6, 12, 8, -
18, and -4 units. What is the mean absolute deviation for these months?
1.16
9.33
10.5
11.67
10.5: To calculate the mean absolute deviation, first make each deviation positive and sum these
absolute values: 15 + 6 + 12 + 8 + 18 + 4 = 63 units. Next, divide by the number of periods (6): 63/6 =
10.5.
When are final assembly schedules typically used?
