Exam 3: Process Choice and Layout Decisions in Manufacturing and Services

Use this scenario for the following question(s). With the backyard poultry craze unleashing a tidal wave of municipal code proposals, Chickenverks is poised to capitalize on the sudden demand for chicken tractors. The portable henhouses they have designed can be assembled in 10 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 40 units per hour. Task Time () Predecessor A 25 \@cdots B 35 A C 20 A D 55 B E 45 C, D F 15 B G 35 C H 40 D, E J 25 F, G K 30 H, J -Refer to the scenario above. Balance the line according to the longest operation rule. What is the efficiency of your line balance?

A(n)________ is a highly automated batch process that can reduce the cost of making groups of similar products.

Takt time sets the upper limit on the elapsed time between completion of successive items on a production line.

The only way to ensure that a layout design is optimal is to try to evaluate literally every possible layout and compute the total distance travelled.

Batch processing is less flexible than a production line and less efficient than a job shop.

A supply chain can have ________ manufacturing processes linked together across multiple partners.

Define the terms front room and back room and describe the roles these processes play in service operations. What must operations managers take into consideration when setting up these two processes?

Products that use standard components but the final configuration of those components is customer-specific are known as:

Use this scenario for the following question(s). 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 7.5 productive hours available in a day and the manufacturer wishes to produce 400 units. Balance the line by assigning tasks to workstations to fill up as much takt time as possible. Break ties by assigning the longest task first. Task Time () Predecessor A 45 \@cdots B 50 A C 20 A D 55 A E 15 D F 65 D G 25 E H 35 B, C, F, G -Refer to the scenario above. How many workstations must be added to increase the output rate to one unit per minute?

A complete makeover by Jose Eber on daytime TV for an unemployed daytime TV viewer that has pretty much given up probably scores:

Activities that take place prior to the point of customization are called upstream activities.

The product-process matrix illustrates that low volume, one-of-a-kind products are ideally suited to a job shop process.

Regardless of the number of tasks or their durations, a line balance that is 100% efficient is achievable if CT = ΣT_i.

The time between completions of successive units on a production line is called:

The product process matrix uses a scale of ________ and ________.

The manufacturing process used to make a wide variety of highly customized products in quantities as small as one is a:

A manufacturer needs to produce 300 coffee pots per 8 hour day. The discrete tasks required to produce a coffee pot have been identified, timed in seconds, and ordered as indicated in the table. Sketch the precedence diagram and then assign tasks to workstations on the production line to achieve the required level of output. Break ties by assigning the longest task first.
