C215 - Chp 10: Facility Layout

ALDEP and CRAFT

Computer software packages for designing process layouts.

Balance delay

The amount by which the line efficiency falls short of 100 percent.

Block plan

Schematic showing the placement of resources in a facility.

Cells

Hybrid layouts that create groups of products based on similar processing requirements

Cycle time

The maximum amount of time each workstation has to complete its assigned tasks.

Efficiency

The ratio of total productive time divided by total time, given as a percentage.

Fixed-position layout

A layout in which the product cannot be moved due to its size and all the resources have to come to the production site.

Flexible layouts

Layouts that remain desirable many years into the future or can be easily modified to meet changing demand.

From-to matrix

Table that gives the number of trips or units of product moved between any pair of departments.

Hybrid layouts

that combine characteristics of process and product layouts.

Immediate predecessor

A task that must be performed immediately before another task.

Intermittent processing systems

Systems used to produce low volumes of many different products.

Layout planning

Deciding on the best physical arrangement of all resources that consume space within a facility.

Line balancing

The process of assigning tasks to workstations in a product layout in order to achieve a desired output and balance the workload among stations.

Mixed-model line

A line designed to produce many versions of a product.

Output rate

The number of units we wish to produce over a specific period of time.

Paced line

A system in which the product being worked on is physically attached to the line and automatically moved to the next station when the cycle time has elapsed.

Process layouts

Layouts that group resources based on similar processes or functions.

Product layouts

Layouts that arrange resources in sequence to allow for an efficient buildup of the product.

REL chart

Table that reflects opinions of managers with regard to the importance of having any two departments close together.

Repetitive processing systems

Systems used to produce high volumes of a few standardized products.

Single-model line

A line designed to produce only one version of a product.

Theoretical minimum number of stations

The number of workstations needed on a line to achieve 100 percent efficiency.
