Exam 9: Layout Strategies

You have been asked to balance a flow shop assembly operation to achieve an output rate of 80 units per eight-hour day. Task times and precedence relationships are shown in the table below. a. Draw the precedence diagram. b. Determine the desired cycle time. c. Determine the theoretical minimum number of stations needed. d. Balance this line using most following tasks. e. What is the efficiency of the line obtained in part d?

One of the major advantages of process-oriented layouts is

The minimum number of workstations depends upon the set of task times and the precedence chart, but not the number of units scheduled.

__________ are fees manufacturers pay to get their products displayed.

What is the primary reason why retailers tend to locate high-draw items around the periphery of the store?

Identify the four requirements for cellular production.

Cyclone Appliances has developed a new European-style convection oven that will be made on an assembly line. The schedule requires 80 ovens in an 8-hour day. The assembly includes seven tasks. The table below indicates the performance time and the sequence requirements for each task. a. What is the cycle time for this assembly operation? b. What is the theoretical minimum number of workstations? c. Draw the precedence diagram.

A work cell is required to make 200 computerized diagnostic assemblies (for installation into hybrid automobiles) each day. The cell currently works an eight hour shift, of which seven hours is available for productive work. What is takt time for this cell?

A(n) __________ addresses flow, allocates space, and responds to customer behavior.

A product-oriented layout would be most appropriate for which one of the following businesses?

__________ refers to the physical surroundings in which a service takes place, and how they affect customers and employees.

Identify the seven fundamental layout strategies. Describe the use of each one very briefly.

Which of the following is not one of the factors complicating the techniques for addressing the fixed position layout?

A firm is planning to set up an assembly line to assemble 40 units per hour, and 57 minutes per hour are productive. The time to perform each task and the tasks which precede each task are: a. Draw a network diagram of precedence relationships. b. Compute the required cycle time per unit in minutes. c. Compute the theoretical minimum number of workstations required to produce 40 units per hour. d. Balance this line using longest processing time. e. What is the efficiency of the line obtained in part d?

The type of layout which features departments or other functional groupings in which similar activities are performed is

The concept of customizing in a warehouse layout

A company is trying to balance production between 3 workstations on an assembly line. Currently there are 5 tasks that need to be performed. These tasks, ABCDE, have required times of 2 minutes, 4 minutes, 1 minutes, 3 minutes, and 10 minutes respectively. The assembly line needs to produce 40 units per day to meet demand and can work for up to 8 hours each day. A. What is the required cycle time? B. What is the theoretical minimum # of workstations? C. Assign the tasks according to shortest task time. D. Is there a better way to divide the work than in Part C?

"Having a focused work center is like having a factory within a factory." Discuss. Include in your discussion what conditions make focused work centers appropriate.

Define the following terms that occur in assembly line balancing: cycle time, minimum number of workstations, and efficiency.

A manufacturing work cell has a takt time of 7 minutes and is staffed by 10 workers. If the work cell delivers 68 units each day find A. The total operation time B. The amount of time worked during the day for all 10 workers combined C. If the plant is open for only 8 hours per day, can the staff meet demand?
