In studying positioning of inventory in supply chains, which, if any, of the following is most appropriate? Image 11
-As order decoupling point moves toward the source, cust lead time increases -As order decoupling point moves towards source, inventory goes down
Breakeven analysis (Choose all that apply)
-seeks to determine the point in units produced where cost equal to revenues -is a standard approach to choosing among alternative processes or equipment
Throughput rate is
1 / cycle time 1 / flow time

What is the best option if forecast is 450 units? image 10
Buy at $200/unit
Which layout is the most suitable when the volume is very high and very low variety? Image 9
Continuous process
If you maintain inventory at a constant level and keep the throughput rate constant:
Customer delivery dates become more reliable
What is DMAIC?
Define, Measure, Analyse, Improve, Control
Which process typically has the longest customer lead time? image 11
Engineer -to- Order
Which is NOT true about production efficiency
Face to face is better than internet
The goal of fail-safe procedures is to hide occurred errors from customers.
False
The simplest way to think about throughput is the quantity of work completed without regard to any time period
False
Select all true statements 2 on the sheet
For process A, the process capacity is 100 loaves per hour For process B, the process capacity is 133 loaves per hour
This methodology refers to the goal of no more than four defects per million units
Sig Sigma
Little law states there is a relationship between
Inventory, flow time, throughput rate
This process layout is most likely a imAGE 8
Job shop
Which is the most likely process used in this work shop? image 7
Job shop
Which process typically appropriate in producing standard products? Image 11
Make-to- Stock
Which station is the bottleneck? Image 3
Pack Orders because it takes the longest time
Which would be the most likely process for making the product shown? image 6
Project
Which is NOT true about high contact system in a bank (branch office)?
Quality standards are measurable and, thus, fixed
Quality management is
Strategies to ensure customer expectations are met
Quality for a product or service is
The ability to meet and exceed customer expectations
The higher is the degree of customer contact in a service operation
The lower is the process efficiency
Capacity is maximum output rate
True
An example of throughput rate sometimes called output rate is units produced per hour
True?
Little's Law
WIP = Throughput rate X Flow time
Which of the following is a key tool in service design?
blueprinting
Which of these is not a basic quality tool?
continuous improvement
Which is true about a Job shop (workcenter) Image 9
cost per unit is high Equipment are general purposes scheduling is complex
This tool can help in identifying possible points in a process where problems occurs
flowchart
Costs such as scrap, rework, or repair can be classified as
internal failure cost
A unique feature of a service blueprint is
line of visibility
Which is NOT a principle of TQM
no defect in the process or system

on, off, sound, color, picture
A diagram that arranges quality problems from highest to lowest frequency of occurrence is a
pareto chart
Costs such as inspection, testing, and other tasks to ensure that the product is acceptable are
preventive costs

the production line approach
Which is NOT a service design approach
the service improvement approach
The term "continuous improvement" is most closely associated with:
total quality management
Generally there is more customer contact in a service organization than in a manufacturing org
yes
