0.72

You have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure. The cycle time of the line is 5 minutes, and the sum of all that tasks required on the line is 25 minutes. Which of the following is the correct value for the resulting line's efficiency?

0.833

You have just determined the actual number of workstations that will be used on an assembly line to be 8 using the assembly-line balancing procedure. The cycle time of the line is 10 minutes, and the sum of all that tasks required on the line is 60 minutes. Which of the following is the correct value for the resulting line's efficiency?

0.750

Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the six tasks that make up the job are 4, 6, 7, 2, 6, and 5 minutes, and the takt time is 10 minutes?

3

The table depicts an assembly line that has been balanced with a takt time of 2 minutes. What is the percent idle time of this balance?

10%

A production line is to be designed for a job with four tasks. The task times are 2.4 minutes, 0.4 minutes, 0.9 minutes, and 2.7 minutes. The smallest possible assigned cycle time is ________ minutes

2.7

Production time available per day is 420 minutes. Scheduled production is 140 units per day. What is the takt time (the required cycle time) (in minutes)?

3

Production time available per day is 480 minutes. The schedule calls for the production of 60 units per day. Each unit of the product requires 30 minutes of work. What is the theoretical minimum number of workstations?

4

Using the assembly-line balancing procedure, which of the following is the theoretical minimum number of workstations if the task times for the eight tasks that make up the job are 7, 4, 7, 8, 9, 4, 3, and 6 minutes, and the takt time is 8 minutes?

6

An assembly line consists of 200 tasks grouped into 20 workstations. The sum of all task times is 100 minutes. The largest assigned cycle time is 8 minutes. What is the efficiency of this line?

62.5 percent

The process design team at a manufacturer has broken an assembly process into eight basic steps, each with a required time, and predecessor as shown in the table. They work a 7 hour day and want to produce at a rate of 360 units per day. What should their takt time be?

70 seconds

Using the assembly-line balancing procedure, which of the following is the takt time in minutes per unit if the daily production time is 480 minutes and the required daily output is 50 units?

9.6

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

This arrangement will help to maximize customer exposure to other items in the store.

n a product-oriented layout, what is the process of deciding how to assign tasks to workstations?

assembly-line balancing

ASRS stands for which of the following?

automated storage and retrieval system

Cycle time is computed as:

daily operating time divided by the scheduled output.

The main issue in designing process-oriented layouts concerns the relative positioning of

departments or work centers

The objective of layout strategy is to:

develop an effective and efficient layout that will meet the firm's competitive requirements.

The process design team at a manufacturer has broken an assembly process into eight basic steps, each with a required time, and predecessor as shown in the table. There are 8 productive hours available in a day and the manufacturer wishes to produce 400 units. What is the theoretical minimum number of workstations needed to balance this line?

five stations

A ________ is also called a plant within a plant.

focused work center

The concept of customizing in a warehouse layout:

incorporates value-added activities in warehouses.

A big advantage of a process-oriented layout is:

its flexibility in equipment and labor assignments.

The main goal of retail layout is:

maximizing profitability per square foot of floor space

In assembly-line balancing, cycle time (the ratio of available production time to scheduled production) is the

maximum time that a product is allowed at each workstation.

The most common tactic followed in process-layout planning is to arrange departments or work centers so they:

minimize the costs of material handling

The major problem addressed by the process-oriented layout strategy is:

minimizing difficulties caused by material flow varying with each product.

The central problem in product-oriented layout planning is:

minimizing the imbalance in the workloads among workstations.

The ________ layout's main objective is to equalize the task time for each station.

process-oriented layout
