Lot for lot is the most common lot sizing technique
True
Conformance quality is a strategic decision for a firm
False
The capability index (Cpk) calculates the percentage of items being produced within specifications

False
If the cost to change from producing one product to producing another were zero the lot size would be very small
True
Lean production makes implementing green strategies in manufacturing processes more difficult
False
Group technology cells help to eliminate movement and queue time between operations
True
In the textbook the expression “quality at the source” means that we need to purchase the best quality a supplier or vendor can provide.

Efficiency means doing the right things to create the most value for the company
false

D. Capacity utilization rate (CUR)
E. Zero-changeover- time (ZXT)
B. Plant within a plant (PWP)
Which of the following models uses a schematic model of the sequence of steps in a problem and the conditions and consequences of each step?
A. Probability indexing
B. Johnson’s sequencing rule
C. Decision trees
D. Activity System Maps
E. Decision mapping
C. Decision trees

C. Least total cost (LTC)
D. Least unit cost (LUC)
E. Warehouse loading factor (WLF)
E. Warehouse loading factor (WLF)

C.Variable overhead
D.Direct labor
E.Inventory costs
B.Prevention costs
What is a capacity cushion and why would a firm have one?
the capacity cushion is an amount of excess capacity over expected demand maintained by a firm. A firm will typically hold capacity cushions when demand is more rapidly variable than capacity adjustments can be
What is the criterion for determining whether a project activity is on the “critical path”
the critical path of activities in a project is the sequence of activities that form the longest chain in terms of their time to complete. The simplest answer would be that perhaps their is a delay in completing the activity will result in a delay in completing the entire project
Define yield management. How does it differ from the pure strategies in production planning?
With yield management, we allocate capacity to customers at the right price and time to maximize revenue. Rather than trying to match demand by adjusting our workforce, inventory or production we adjust demand so that it better matches our production capability. The two approaches compliment one another
What does it mean when we say that a process is capable?
We say the a process is capable when the mean and standard deviation of the process are operating such that the upper and lower control limits are acceptable relative to the upper and lower specification limits
What is sustainability? What can we do at our personal level to promote sustainability?
The ability to meet current resource needs without compromising the ability of future generations to meet their needs. In other words, it is a way of life where our resources are managed well and the big and obvious risks are avoided and a way of life that can continue for generations. At personal level we all can
, Walk more and drive (car) less Fly less (by airplanes) Reduce/ reuse/recycle as much as possible

One of the assumptions made using CPM is that project activities can be identified with clear beginning and ending points.
true
.The term “assembly line” refers to progressive assembly linked by some material handling device
true

B. A definition of the hierarchy of project tasks, subtasks, and work packages
C. A depiction of the activities making up a project
D. A Gantt chart
E. A structure that is incompatible with the Critical Path Method
a definition of the hierarchy of project tasks, subtasks, and work packages
Which of the following are the three major components of a queuing system?
A. The source population, how customers exit the system and the queuing discipline
B. The number of servers, the service speed and the waiting line
C. The source population, how the customer exits the system and the servicing system.
D. The source population and the way customers arrive at the system, the servicing systems, and how customers exit the system.
E. The service speed, the queue discipline and the waiting line
the service speed, the queue discipline and the waiting line

B. Inventory on hand and financing costs for that inventory
C. The strategic plan and the products available for sale
D. The workforce level and the degree of automation
E. Operational costs and the cash flow to support operations
workforce level and inventory on hand
