in a location problem, minisum is generally used to - correct answer ✔minimize the total travel time
minisum - correct answer ✔minisum minimizes total travel distance, minisum minimizes total travel
time
compare the work in process WIP inventory with the pull method vs the push method - correct answer
✔WIP in push is higher
which statements are correct:
a. no input to a pull system will results in shortage
b. on a pull system, no demand will result in no production
c. the amount of WIP of a pull system, may exceed the number of kanban used
d. with the same number of kanbans and buffers, a pull system will have equal or more WIP than the
push system
e. on a pull system, machine breakdown will result in stop of production - correct answer ✔a b e
in order to use the inventory model, which of the following assumptions must be made - correct answer
✔demand rate is constant over time, production rate is constant over time
what are the benefits of the JIT system - correct answer ✔higher productivity
the following are NOT true of the JIT system
, a. demand is known with certainty and is relatively constant over time
b. machines can never be idle
c. lead time for the receipt of order is short
d. inventory costs are minimized
e. finished products are always delivered just in time - correct answer ✔b
just in time JIT characteristics - correct answer ✔shorter lead time, higher productivity, increased team
work
just in time production has these characteristics - correct answer ✔it produces a throughput versus
WIP curve very similar to the curve for the push system, production capacity must be known, it requires
short lead time
what happens when there is no input in the pull system - correct answer ✔shortage occurs
which of the following are characteristics of a pull system - correct answer ✔shorter lead time, more
product variety
which of the following statements describe a pull system
a. machine stays idle until theres a need for the product
b. by material, then feed it into the machine when it becomes idle
c. it will never get flooded
d. inventory is always constant
e. it is triggered by demand - correct answer ✔a c d e
