A tortilla chip workstation produces 1,000 chips in 20 seconds. What is its bottleneck time? 20 seconds 6000 chips per minute 20,000 seconds 50 chips per second .02 seconds per chip
.02 seconds per chip
Value-stream mapping: is a variation of time-function mapping. examines the supply chain to determine where value is added. extends time function mapping back to the supplier. starts with the customer and works backwards. All of these are true.
All of these are true.
A system using an automated work cell controlled by electronic signals from a common centralized computer facility is called: robotics. a manufacturing cell. a flexible manufacturing system. an adaptive control system. an automatic guided vehicle (AGV) system.
a flexible manufacturing system.
Product focused processes: are desirable because resource needs increase slowly with the complexity of a process. are profitable because customers demand flexibility, not specialization. are processes that are specialized for relatively few products or customer groups. apply only to service firms, not to manufacturers. allow more customization, but are not very efficient.
are processes that are specialized for relatively few products or customer groups.

In the mass service and service factory quadrants of the service process matrix, the operations manager could focus on all of the following except: standardization. customization. tight quality control. automation. removing some services.
customization.
In "drum, buffer, rope," what provides the schedule, i.e. the pace of production? drum buffer rope all three of these in combination None of these

What is a drawing of the movement of material, product, or people? service blueprint process chart flowchart process map vision system

Consider the assembly line below. The three fabrication operations run in parallel, such that each batch of 20 units only needs to go through one of the three fabrication operations. After that, each batch needs to go through both assembly operations, which occur simultaneously (specifically, 10 components are made for each unit in the fabrication stage-some components are then assembled in the Assembly 1 area while others are assembled in the Assembly 2 area). The units are packaged and made ready for shipment in the final stage. What is the bottleneck time per batch of this operation? 88 min. 24 min. 8 min. 34 min. 3 min.
8 min.
Consider a production line with five stations. Station 1 can produce a unit in 9 minutes. Station 2 can produce a unit in 10 minutes. Station 3 has two identical machines, each of which can process a unit in 12 minutes (each unit only needs to be processed on one of the two machines. Station 4 can produce a unit in 5 minutes. Station 5 can produce a unit in 8 minutes. Which station is the bottleneck station? Station 1 Station 2 Station 3 Station 4 Station 5
Station 2
Which of the following characteristics best describes repetitive focus? Its output is a standardized product produced from modules. It is widely used for the manufacture of steel. low volume, high variety Operators are broadly skilled. It uses sophisticated scheduling to accommodate custom orders.
low volume, high variety
Which of the following represents an aggressive approach to demand management in the service sector when demand and capacity are not particularly well matched? lower resort hotel room prices on Wednesdays appointments reservations first-come, first-served rule None of these

Which of the following are all strategies for improving productivity in services? reduce inventory, reduce waste, reduce inspection, and reduce rework lean production, strategy-driven investments, automation, and process focus high interaction, mass customization, service factory, and just-in-time process focus, repetitive focus, product focus, and mass customization focus separation, self-service, automation, and scheduling
separation, self-service, automation, and scheduling
One fundamental difference between a process chart and a flowchart is that: the process chart adds a time dimension to the horizontal axis, while a flowchart is not time-oriented. the process chart includes the supply chain, while the flowchart stays within an organization. the process chart is more like a table, while the flowchart is more like a schematic diagram. the process chart focuses on the customer and on the provider's interaction with the customer, while the flowchart does not deal directly with the customer. None of these is true, because a process chart and a flowchart are the same thing.
the process chart is more like a table, while the flowchart is more like a schematic diagram.
One of the similarities between process focus and mass-customization is: the volume of outputs. the use of modules. many departments and many routings. the variety of outputs. All of these are similarities.
the variety of outputs.
