Exam 9: Layout Strategies

An assembly line has been designed to make battery-powered beverage mixers. Task details are shown in the table below: Station Task Assigned Task Time (minutes) 1 1 3.0 2 3;4 1.5;2.0 3 2;5;6 1.5;1.5;1.0 4 7 3.0 5 8 2.5 6 9;10;11 2.0;1.0;1.0 a. What is the assigned cycle time (in minutes)? b. What is the maximum output rate of this line in mixers per hour? c. What is the total idle time per cycle? d. What is the assembly line's efficiency?

Cycle time is computed as

Ambient conditions, spatial layout and functionality, and signs, symbols, and artifacts are all

An assembly line consists of 21 tasks grouped into 5 workstations. The sum of the 21 task times is 85 minutes. The largest assigned cycle time is 20 minutes. The efficiency of this line is

The fixed-position layout would be most appropriate in which of the following settings?

Category management is the use of computer software to evaluate the profitability of merchandising plans.

A work cell is scheduled to build 120 digital light processor (DLP) assemblies each week. These assemblies are later installed into home theatre projection systems. The work cell has 7.5 hours of productive work each day, six days per week. What is takt time for this cell?

A facility is trying to set up an assembly line, and has identified the various tasks, and their relationship to each other, as shown in the following table. They wish to produce 600 units per day, working two 8-hour shifts. Task Preceding Task Time to perform (sec.) A -- 20 B -- 30 C -- 25 D -- 10 E A 55 F D, B, C 30 G E 25 H F, G 40 a. Draw a network diagram of precedence relationships. b. Compute the required cycle time per unit in seconds. c. Compute the minimum number of workstations required to produce 600 units per day. d. Balance this line using longest processing time. e. What is the efficiency of the line obtained in part d?

Balancing a work cell is done

The biggest advantage of a product layout is its flexibility to handle a varied product mix.

In a product-oriented layout, the process of deciding how to assign tasks to workstations is referred to as

There are three work centers (A, B, and C) behind the financial aid counter at a nearby university. They can each fit into any of three office spaces (1, 2, and 3) off the corridor behind the desk. There is no student contact in these areas, only workers. The distance 1-2 is 20 feet, 2-3 is 30 feet, and 1-3 is 50 feet. The matrix of work (trips per day) at the three centers is in the following table. Remember that each trip must be a round-trip (from 1 to 2 and back, for example). -- 20 0 45 -- 25 60 0 -- a. How many possible assignments are there? List them. b. Calculate the total distance traveled in each of these assignments. c. Which assignment minimizes distance traveled?

The assumption of stability of demand is important for justifying which of the following layout types?

Which of the following constitutes a major trend influencing office layouts?

One of the major advantages of process-oriented layouts is

________ avoids placing materials or supplies in storage by processing them as they are received for shipment.

Which of these layouts is most suitable for processing sugar from sugar beets or sugar cane?

A process-oriented layout is the traditional way to support a product differentiation strategy.
