Concept explainers
a)
To determine: The decision table for the decision.
Introduction: Decision table is formats or visual representations were data is expressed arranged, determined and calculated to make a effective decision making. A decision table is a tabular representation that is used to analyze decision alternatives and states of nature.
b.
To determine: Maximax decision
Introduction:
Maximax is the decision making method which come decision making under uncertainty. This method finds an alternative that maximizes the maximum outcome of each alternative or we can say that calculating the maximum outcome within every alternatives.
c.
To determine: The minimax decision.
Introduction
Maximin is the decision making method which makes decision making under uncertainty. This method will find an alternative that maximizes the minimum outcome of every alternative or we can say that calculating the minimum outcome within the each alternative.
d.
To determine: Equally likely decision
Introduction
Equally likely is the decision method which come decision making under uncertainty. Under this condition, equal probability is assigned under each uncertainty state of nature.
e.
To draw: Decision tree. Assume each outcome is equally likely, and find the highest EMV.
Introduction:
Decision tree is graphical representation of decision making process which has state of nature, alternative, payoffs and their probabilities of outcomes.
EMV: It is expected value or payout that has different possible state of nature, each with their associated possibilities.
Formula:
Here probabilities are equal likely in each case. So probabilities of the be 1/3= 0.3333

Chapter A Solutions
Operations Management
- A copy machine is available 24 hours a day. On a typical day, the machine produces 100 jobs. Each job takes about 3 minutes on the machine, 2 minutes of which is processing time and 1 minute is setup time (logging in, defining the job). About 20 percent of the jobs need to be reworked, in which case the setup time and the processing time have to be repeated. The remainder of the time, the equipment is idle. What is the OEE of the equipment?arrow_forwardHow do you think we can keep updating Toyota's ideas as new technologies come out and what customers want keeps changing?arrow_forwardGiven how TPS has helped change things in so many fields, do you think there are parts of it that might be hard to use in areas that aren’t about making things, like in healthcare or services? If so, why do you think that might be?arrow_forward
- Do you feel there is anything positive about rework?arrow_forwardDo you think technology can achieve faster setup times? How would it be implemented in the hospital workforce?arrow_forwardIn your experience or opinion, do you think process changes like organizing workspaces make a bigger difference, or is investing in technology usually the better solution for faster setups?arrow_forward
- Have you seen rework done in your business, and what was done to prevent that from occurring again?arrow_forwardResearch a company different than case studies examined and search the internet and find an example of a business that had to rework a process. How was the organization affected to rework a process in order to restore a good flow unit? Did rework hurt a process or improve the organization's operational efficiency? • Note: Include a reference with supportive citations in the discussion reply in your post.arrow_forwardSetup time is very important in affecting a process and the capacity of a process. How do you reduce setup time? Give examples of reducing setup time. Please Provide a referenecearrow_forward
- Do you think TPS was successful? If so, how? Are there other companies that have used TPS? If so, give examples. Please provide a referencearrow_forwardGiven the significant impact on finances, production timelines, and even equipment functionality, as you pointed out, what do you believe is the most effective single strategy a company can implement to significantly reduce the occurrence of rework within their operations?arrow_forwardDurban woman, Nombulelo Mkumla, took to social media last week to share how she discovered the rodent.In a lengthy Facebook post, she said she purchased the loaf of bread from a local shop after work on August 27.For the next days, Mkumla proceeded to use slices of bread from the load to make toast."Then, on the morning of August 31, I took the bread out of the fridge to make toast and noticed something disgusting andscary. I took a picture and sent it to my friends, and one of them said, 'Yi mpuku leyo tshomi' [That's a rat friend]“."I was in denial and suggested it might be something else, but the rat scenario made sense - it's possible the rat got into thebread at the factory, and no one noticed," Mkumla said.She went back to the shop she'd bought the bread from and was told to lay a complaint directly with the supplier.She sent an email with a video and photographs of the bread.Mkumla said she was later contacted by a man from Sasko who apologised for the incident.According to…arrow_forward
