lecture 2 Flashcards
design of the process should be
quality, speed, dependability, flexibility, cost, sustainable performance
throughput rate
flow rate/ the rate at which items emerge from the process, that is the number of items passing through the process per unit time
cycle time
take time, time elapsing between output, tact
throuput time
the average elapsed time taken for inputs to move through the process and become outputs
utilisation
the proportion of available time that the resources within the process are performing useful work
work in process
number of units in the process as an average over a period of time
project processes
complex. large scale, high work, specially made, every customised, defined start and finish, waltz and cost objectives, many different skills have to be coordinated , software, ships, movie production
jobbing proceses
high variety, low volume, each product shares operations with other, similar attentions but differ in exact needs, furniture, printer, craftsman
batch processes
different variety and volume, I batches, machine tool manufacturing, food, mass production details
mass process
low variety, high volume, standardise
continuous proceses
high volume, low variety, often single product, chemical, repeat, highly capital, difficult to start and stop process
process maping
describing processes in terms how the activities within the process relate to each other
circle
operation
square
inspection
arrow
transport
