Question

Stats homework practice:

1) The role of operations is to use resources to transform inputs into outputs. From this perspective, what is the most important input for a Highway?

A) Roads to take the people to their destination

B) Cement for the cars to drive on

C) People in cars on their way to their destination

D) Road signs to inform the people about where to go

2) One way to look at Operations Management is by saying that it looks for the best way to do something, and then do it that way. This doesn't guarantee the best outcome every single time, but it does mean that (finish the sentence)...

The best outcome is guaranteed at least once

The average outcome is always achieved

The worst outcome is always avoided

The best average outcome can be achieved

3) Which of the following products is most likely produced in a Job Shop?

Custom made motor bikes

Airplanes

Frozen pizzas

Crude Oil

4) Currently, a production process with multiple stages and several machines at each stage is producing large orders in small batches (i.e., more batches than there are machines at some stages). What will happen if they reduce variability in process times at each stage (but do not change the mean process time at any stage)?

Lower throughput time, unchanged utilization

Lower throughput time, lower utilization

Higher throughput time, lower utilization

Higher throughput time, unchanged utilization

5) Consider these two statements about batching:

1) Splitting up larger orders into the smallest possible batch (i.e., one unit at a time) is always the best decision.

2) Combining smaller orders into the largest possible batch (e.g., all units ordered during an entire day) is always the best decision.

Statement 1 is false, statement 2 is true

Statement 1 is true, statement 2 is false

Both statements are true

Neither statement is true

Answer 1

B - Cement For The Cars To Drive On

The development of proper roads would be considered as operations because highways are made in order to provide benefits to the people of the country in order to travel from one city or state to another through road. Cement, would be an input for development of roads. Using high quality cement is a must for every country because the no of vehicles which will use the highway will be very high. A highway is a costly project and should be made with a view of long life.

Use of lower quality or cheap products in the making of highway can be very dangerous for the public as they can face major accidents, engine failures or anything that can cost them or their families serious injuries or even death. The fundamentals of CEMENT-TREATED BASE are below-

- Proper Cement Content

- Adequate Moisture Content

- Thorough Mixing

- Adequate Compaction

- Proper Curing

Why other options are not suitable with the question?

A- A higway is a long road. Road can be considered as a output generated from input transformation with CEMENT as input.

C- People in car will be considered as the users of the output generated. A highway is made for the convinience of the people.

D- Road signs are important but not an input and if a person takes the wrong route there are many ways by which he can come on the right route.

C - The Worst Outcome Is Always Avoided

In operations management, the team always practice to use the available resources in the best possible way in order to achieve the objective effectively and efficiently. "Looking and finding for the best way to do something and then do it that way" the statement defines that the team should look to do operations by finding the effective and efficient way i.e minimizing costs, timely goal achievement etc.

But there is always a risk of a complete failure comes with every plan. Operations Mangement process is a huge gamble if you see with company's perspective. One wrong operation and all the efforts will be in vein in no time. The possibility of worst outcome is always very high in terms of operations management.

Why other options are not suitable with the question?

B- There is not gurantee of any outcome in operations management. If any process gurantees an achievement of even average outcome, then most of the businesses will adopt it forever.

A- The is not theory or principle says that the outcome will be surely achieved at once in the end. The principle is practice makes a person perfect and even a perfect person can't give gurantee that the outcome will be achieved at once.

D- Even the best average outcome is not sure. There are two results for which an operations team work i.e success or failure. Any outcome cant be predicted and can change with time and quality of operations.

A - Custom Made MotorBikes

Job Shop

A job shop can be defined as a business that makes specific products for one customer at a time. The company customises the product in accordence to the specifications and wants of the customer. The business only makes the product on order from the customer,

EXAMPLES OF JOB SHOPS- A commercial printing shop, Cutomised cars/bike showroom etc.

Why other options are not suitable with the question?

B- Airplanes, are huge project and impossible to made in a job shop. Airplanes are made up of aluminium while sometimes steel and titanium also being used. Airplane can be customised for brands, business empires but not for an individual and most importanty can't be processed through a job shop.

C- Frozen Pizzas are the product of dairy or restaurants and nothing can be done in a job shop regarding a pizza.

D- Crude oil is a natural oil and refined to produce usable products such as gasoline, diesel etc and job shop has no relation by far from the production of crude oil.

4.

C - Higher Throughput Time and Lower Utilisation, reduced variability in process time will increase the average manufacturing throughput time. The overall effect will increase the costs, to increase customer lead times and to reduce delivery reliablilty.

Why other options are not suitable for the question.

A- The utilisation will be decreased and throughtime will be higher than average.

B- The throughtime will be on the higher side.

D- The utilisation will decrease.

B. Statement 1 is true, statement 2 is false

Splitting up larger orders into the smallest possible batch is always the best decision. The larger orders means longer time durations needed and more human resources. So, splitting the orders according to the resources you have will be the best practice in order to complete the orders with achievement or effectiveness and efficiency.

Why other options are not suitable with the question?

A- Combining small order into larger batches always gives rise to workload problems. Generally operations team believe in processing of the orders in quickest of times with proper usage of resources. Small orders can be processed single handedly or by minimal workforce, so why combining them?
