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

The three dimensions of service positioning are the nature of the service package,the degree of customization and the degree of customer contact.

What are the two types of product-based layouts? What are their similarities and differences and their advantages and disadvantages compared with other types of layouts and processes?

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

Capability variety is the difference in how customers view an identical service outcome.What some customers might view as economical and thrifty others might view as cheap and poor value.

A product-based layout arranges resources sequentially according to the steps required to make a product.

Use this scenario for the following questions. 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. -Refer to the scenario above.Without using more than one worker per station,what is the maximum output achievable in the 7.5 hour work day?

Highly automated batch processes that can reduce the cost of making similar groups of products are:

Champion Cooling has just signed a contract to assemble window air conditioners for another company.The list of tasks,including time requirements and immediate predecessors,follows.Initially,the plan was to make 300 units in an eight hour day but as the summer months approach,Champion Cooling finds themselves far behind in total production.They wish to reconfigure their production line in order to produce maximum output.What should their takt time be?

An assemble-to-order process occurs upstream from:

As the degree of service customization decreases,managers have more opportunity to focus on cost and productivity.

Use this scenario for the following questions. 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. Use this information to answer the following questions. -Refer to the scenario above.Operations managers and process engineers design a line that contains seven stations.What is the percentage of idle time?

The table depicts a production line that has been balanced with a takt time of 2 minutes.If you could hire another six workers,which of these systems would result in the highest output rate?

A job shop manufacturing process is better suited to make a variety of products than a continuous flow process.

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?

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.

The table depicts a production line that has been balanced with a takt time of 2 minutes.What is the efficiency of this balance?

Use this scenario for the following questions. 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. -Refer to the scenario above.Balance the line according to the longest operation rule.What is the efficiency of your line balance?

"My tour of the Duff Brewery was the greatest experience of my life," Homer recalled.Lenny's favorite part was the batch process that was evident during the fermenting stage but Carl's favorite part was the high speed continuous flow process evident in the bottling line."You're both right," Homer declared,"Duff takes both elements to create a(n)________ process."

No manufacturing process can be best at everything.
