Operations Analytics Model

 

7BSM2003 Operations & Business Analytics

Assignment Title:

Excel Modelling and Reporting

Description of the assignment:

Background

(Any similarities to the student shop at the University of Hertfordshire are entirely coincidental. This is a fictional example.)

The Students’ Union Shop is trying to work out how many cashiers it needs to employ in order to provide an adequate service level. Customers at the shop line up in a single queue and are called forward to pay for their purchases when a till becomes free. To help determine the busy times of the day, the shop has recorded the number of customers arriving at the tills in each 5-minute interval during the shop’s opening hours, from 8am until 6pm (N.B. this is the number who actually make a purchase and does not include customers who are just browsing). Records for a period of 5 weeks are available. All the data were collected during term time.

The shop usually functions with just three cashiers but it has the capacity to support up to 6. The shop is open for approximately 50 weeks each year. The management has also collected data about the time it takes for cashiers to take payment. These data come from term time and 1000 records are available. Management are concerned that customers wishing to buy food, in particular, may be going to other outlets within the university such as the Big Ears Sandwich Shop or the Noddy Bar. Management are also concerned about the turnover of their staff and would like to reduce their stress and also stop them getting bored. They would be interested to hear about any innovative operating strategies for doing this.

7BSM2003 Operations & Business Analytics

You are employed as a consultant for the Students’ Union Shop. The shop management would like to hear insights from you, but does have a few specific questions they would like to ask. These questions are

  • What is the average customer arrival rate per hour based on the current data?
  • The management reckons there are more customers during the lunch break, and would like you to look into this matter. Could you spot any busier period during the day? If so, what are the busier hours?
    • What is the average customer arrival rate per hour during busier period?
    • What is the average customer arrival rate per hour during quieter period?
  • How fast on average does a cashier serve a customer in our shop?
    • Have you spotted any outlier in the collected service data? If yes, did you include (or exclude) those outliers when coming up the average, and why?
  • How many cashiers does the shop need to have a reasonable performance?
    • When taking the average daily arrival? Would you consider the average daily arrival a good measure for cashier arrangement, and why?
    • During busier period if observed?
    • During quieter period if observed?

What You Should Produce

You are required to produce a model using Excel, which could be used by the Students’ Union Shop management team for evaluation of their performance using the data provided or any new data that becomes available in a similar format. If there is any further information you believe to be essential, make a realistic assumption and explain clearly what you have done (in the report below).

The model should be supported by a report (using Report Sheet) in which you should address management’s questions listed above. They are looking for calculations (e.g. average arrival rate) and short explanations, where applicable. You are also expected to give convincing arguments to support your answers, e.g. by showing the benefit of adding an extra cashier in terms of staff utilisation and customer waiting time. APA.

  • What is the average customer arrival rate per hour based on the current data?,

  • The management reckons there are more customers during the lunch break, and would like you to look into this matter Could you spot any busier period during the day If so what are the busier hours?,

  • How fast on average does a cashier serve a customer in our shop?,

  • How many cashiers does the shop need to have a reasonable performance?,

  • Would you consider the average daily arrival a good measure for cashier arrangement and why?,

CJ406 Media Case

  Overview

In this assignment, you will summarize a criminal case in which the broadcast media had an impact, and explain how the media may have influenced the public’s perception of the case.

Prompt

In this module, you learned about ways in which perceived bias in media coverage of criminal cases and police activity may play a role in society’s perception of police. One of those ways is the role the media play in a criminal case. If the media are biased, it may impact how society interprets and reacts to a criminal case and the criminal justice professionals involved. The media’s involvement in a case can also affect criminal justice practices. For this assignment, you will choose a criminal case to focus on. This case will be the basis for both this assignment and Project Three, which is due in Module Seven. You will craft a summary of the case and explain how the media may have influenced the public’s perception of the case.

CJ406 Media Case

 

CJ406 Module Four Assignment

First, choose the case of one of the following criminals:

William R. Horton

Pamela Smart

Dominic Cinelli

George Zimmerman

As you begin to research the case, the Project Three Case Resources PDF document may be of assistance.

Then, address the following rubric criteria:

In 75 to 100 words, craft a brief summary of a criminal case in which the media had an impact.

  • In 75 to 100 words craft a brief summary of a criminal case in which the media had an impact,

  • Describe the pertinent facts and legal points of the case,

  • Describe who was involved and where the case took place,

  • In 100 to 150 words explain how the media may have influenced the public’s perception,

  • Describe any actions by the public that may have been a result of the media’s influence and explain the role the media may have played in the public’s perception of the criminal justice professionals involved in the case and or practices related to the case,

HWE 415 Stress Management

 Prior to beginning work on this assignment, review Chapters 1, 2, and 3 from the course text, read the article by Keller et al., (2012), Does the Perception That Stress Affects Health Matter? The Association With Health and Mortality, and watch Seriously Stressed. Many of you may be familiar with the classic tale of George Bailey (James Stewart) in It’s a Wonderful Life. George Bailey portrays a young man who encounters many major life events. Although he has ambitions to go to college and travel the world, the death of his father crushes his dreams. He decides to stay in his hometown to manage the family business, Bailey Building and Loan. Over the years, Henry F. Potter, George’s nemesis, tries to take over the family business as it struggles with financial difficulties. As time passes, George Bailey marries and has four children. George’s major stressor presents itself, and the way he perceives and reacts to this stressor, paves the way for the outcome of the movie. While George tries to run away from this stressor, the support of his family and friends help him through it.

HWE 415 Stress Management

 

HWE 415 Stress Management

To get a brief overview of the movie, watch It’s a Wonderful Life Trailer (2:11). Be sure to watch Frank Capra’s 1946 version of the film. Then search for the following clips that depict some of George’s stressful moments:

It’s A Wonderful Life – Potter’s Offer.mov – YouTube

View for the fight or flight response:

It’s a Wonderful Life Bank RunLinks to an external site. (4:00)

Character Study:

  • Identify four of George’s stressors; these can be distressful or eustressful events.
    • Support these examples of stress with the course text.
  • Assess George’s physiological, social, and emotional reactions to these stressors in the movie.
    • Provide two examples of George’s physiological reactions.,
    • Provide two examples of George’s social reactions.,
    • Provide two examples of George’s emotional reactions to his stressors.,
    • Use the course text as a minimum to support your response; the movie should be cited when it is being explained.

HWE 415 Stress Management

Throughout the movie, George encounters many stressors, but there are two major stress events that he must decide whether to “fight or flight.” The fight-or-flight response is a way the body reacts to stress. When faced with a stressor, the body prepares to fight it or run away from it. After watching the video clips above,
