OPMT 303 CH 6 Concepts – Flashcards

A product-focused, single-piece flow, pull production system would be called a: continuous flow. assembly line. cellular layout. job shop. nonrepetitive process.

Which of the following is not a process commonly considered in making products or delivering services? subcontracting batch repetitive job shop continuous

As a general rule, continuous processing systems produce products for inventory rather than for customer order. True False

As compared to rigid automation, the benefits of flexible manufacturing systems include: reduced labor requirements. significantly lower fixed costs. significantly lower variable costs. larger batch sizes. higher efficiency.

If a line is balanced with 80 percent efficiency, the "balance delay" will be: 20 percent. 80 percent. depends on the next operation. unknown, since balance delay is not related to efficiency. 100 percent.

In an environment in which demand is both substantial and stable, __________ technology tends to be the best choice. flexible automation fixed automation project production programmable automation batch production

A process layout is more susceptible to shutdowns caused by equipment breakdowns than a product layout. True False

Product layouts involve high utilization of labor and equipment. True False

Morale problems can be a reason for redesign of a facility layout. True False

The substitution of machinery that has sensing and control devices for human labor is best described by the term: computer-integrated manufacturing. automation. flexible manufacturing system. feedback control. computer-aided manufacturing.

A cafeteria line would be an example of a process-focused layout. True False

A production line is to be designed for a job with three tasks. The task times are .4 minutes, 1.2 minutes, and .5 minutes. The maximum cycle time in minutes is: 1.4. 2.1. .7. .8. .3.

The estimation of costs is generally most difficult when the ___________ process has been chosen. project repetitive job shop batch continuous

The term "computer-aided manufacturing" refers primarily to the use of robotics in process control. True False

Job shops tend to be __________ while continuous processes tend to be __________. short-term and capital intensive; long-term and labor intensive low cost-per-unit; high cost-per-unit small scale and flexible; large-scale and inflexible in services; in manufacturing standardized; customized

Daily capacity of a product layout is determined by: operating time divided by total task time. cycle time divided by operating time. operating time divided by cycle time. cycle time divided by total task time. total task time divided by cycle time.

The minimum possible cycle time in a product layout is determined by the: per-unit setup time. longest task time. total task time. shortest task time. average task time.

Service layouts must be visually pleasing as well as functional. True False

Cellular layout is a term associated with: functional (or process) layouts. wireless telecommunication. assembly lines. part families. job shops.

Right-sized equipment tends to be larger than equipment used in traditional process layouts. True False

Repetitive processing systems usually produce goods specifically for customer orders rather than for inventory. True False

Which phrase most closely describes flexible manufacturing systems? a more fully automated version of cellular manufacturing a variation of CAD a process layout with a manufacturing overlay manufacturing resource planning an approach that allows workers to begin work at a time of their choosing

Intermittent processing can take the form of batch processing or a job shop. True False

In which type of operation are you likely to see, at most, only minor variations in the product or service being produced using the same process and the same equipment? a job shop intermittent production a project batch processing repetitive production

A disadvantage of a product layout can be high in-process inventory costs. True False
