Cycle time - CORRECT ANSWER- the average time between the start of production of one unit and the
start of production of the next unit of production
lead time or sojourn time - CORRECT ANSWER- the time it takes for one unit to move through the
system beginning to end
processing - CORRECT ANSWER- being worked by a resource
takt time - CORRECT ANSWER- the rate at which a finished product needs to be completed in order to
meet customer demand
value added - CORRECT ANSWER- a processing step which transforms raw materials or work in progress
into a more valuable good and service to customers
workstation - CORRECT ANSWER- work area that is set up to perform a processing step in the
manufacturing process
work in process (WIP) - CORRECT ANSWER- is the product between the start and end points of a
product routing
,work in process (WIP) does not include - CORRECT ANSWER- Raw Material Inventory (RMI) or Finished
Goods Inventory (FGI)
what is an assembly line? - CORRECT ANSWER- An assembly line is a manufacturing process (often
called a progressive assembly) in which parts (usually interchangeable parts) are added as the semi-
finished assembly moves from workstation to workstation where the parts are added in sequence until
the final assembly is produced
bottleneck - CORRECT ANSWER- - A bottleneck is a point of congestion in a production system that
occurs when parts arrive faster than they can be processed
- A bottleneck has no idle time
capacity - CORRECT ANSWER- the upper limit for throughput in a production process
muda - CORRECT ANSWER- "futility; uselessness; wastefulness"
7 types of muda - CORRECT ANSWER- transport, inventory, motion, waiting, overproduction, over
processing, defects
manual assembly line - CORRECT ANSWER- - A production line consisting of a sequence of workstations
where assembly tasks are performed by human workers as the product moves along the line.
- Very few "pure" manual assembly lines in the USA
automated assembly line - CORRECT ANSWER- - Robotic spot welding lines in automotive final assembly
- 100% Difficult for now!!
hybrid assembly line - CORRECT ANSWER- - Mixture of manual vs automated assembly process.
- 15- 85% automation
, total work content - CORRECT ANSWER- the sum of all work elements required to assemble one
product unit on the line
why are assembly lines so productive - CORRECT ANSWER- - specialization of labor
- interchangeable parts
- work flow principle (products -> workers)
- line pacing
specialization of labor - CORRECT ANSWER- minimize skilled labor
interchangeable parts - CORRECT ANSWER- components made to close tolerances
workflow principle - CORRECT ANSWER- "Place the tools and the men in the sequence of the operation
so that each component part shall travel the least possible distance while in the process of finishing." -
Henry Ford
line pacing - CORRECT ANSWER- Workers must complete their tasks within the cycle time of the line
factors favoring the use of assembly lines - CORRECT ANSWER- - High or medium demand for product
- Identical or similar products
- Total work content can be divided into work elements
- It is technologically impossible or economically
infeasible to automate the assembly process
hard product variety - CORRECT ANSWER- products differ substantially
