Chapter 3: Manufacturing models and metrics

What is the cycle time in a manufacturing operation?

• The number of work units completed per hour

• The total time from when the operation begins to the point-of-time at which the operation ends

• The time interval between the instant of the occurrence of a specified input condition to a system and the instant of completion of a specified operation

• The number of business days between receiving an order for a product and shipping the product

The bottleneck station is the _______ workstation in a production line, and therefore it limits the pace of the entire line.

What is production capacity?

• The ability of time to transfer work units between each cycle

• The maximum rate of output that a production facility is able to produce under a given set of assumed operating conditions

• The ability of someone or something to hold something

• The maximum output that a business can produce in a given period with the available resources

How can plant capacity be increased or decreased in the short term?

• To reduce number of shift per week

• To change the number of work shifts per week

• To reduce the production rate

• To change the number of hours worked per shift

What is utilization in a manufacturing plant?

• Utilization is the actual quantity produced by the facility relative to its capacity

• Utilization is the amount of output of a production facility relative to its capacity

• Utilization is the proportion of time that a piece of equipment is up and working properly

Choose the example of typical factory overhead expenses?

• Plant supervision

• Security personnel

• Power for machinery

• Clerical support

What is availability?

• Availability is the amount of output of a production facility relative to its capacity.

• Availability is a reliability metric that indicates the proportion of time that a piece of equipment is up and working properly

• Availability is the quantity of parts or products currently located in the factory that are either being processed or are between processing operations

What is manufacturing lead time?

• Manufacturing lead time is the total time required to process a given part or product through the plant, including any lost time due to delays, time spent in storage, reliability problems, and so on.

• Manufacturing lead time is the operation time at the bottleneck station

• Manufacturing lead time is the cycle of time of the production line
