Ch 10 - Facility Layout Flashcards
layout planning
deciding on the best physical arrangement of all resources that consume space within a facility
intermittent processing systems
systems used to produce low volumes of many different products
repetititive processing systems
Systems used to produce high volumes of a few standardized products
process layouts
layouts that group resources based on similar processes or functions
best for intermittent processing systems
product layouts
layouts that arrange resources in sequence to allow for an efficient buildup of the product
hybrid layouts
layouts that combine characteristics of process & product layouts
group technology (GT) or cell layouts
hybrid layouts that create groups of products based on similar processing requirements
fixed-position layout
a layout in which the product cannot be moved due to its size & all the resources have to come to the production site
block plan
schematic showing the placement of resources in a facility
from-to matrix
table that gives the number of trips or units of product moved between any pair of departments
REL chart
table that reflects opinions of managers with regard to the importance of having any two departments close together
ALDEP & CRAFT
Computer software packages for designing process layouts
flexible layouts
line balancing
the process of assigning tasks to workstations in a product layout in order to achieve a desired output & balance the workload among stations
immediate predecessor
a task that must be performed immediately before another task
precedence diagram
a visual representation of the precedence relationships between tasks
output rate
the number of units we wish to produce over a specific period of time
cycle time
the maximum amount of time each workstation has to complete its assigned tasks
theoretical minimum number of stations
the number of workstations needed on a like to achieve 100% efficiency
efficiency
the ratio of total productive time divided by total time, given as a %
balance delay
the amount by which the line efficiency falls short of 100%
paced line
a system in which the product being worked on is physically attached to the line & automatically moved to the next station when the cycle time has elapsed
single model line
a line designed to produced only one version of a product
mixed-model line
a line designed to produce many versions of a product
