I would like to write about this new project that would expand public transportation in the Soundview area of the Bronx. An abandoned dock is being remodeled and rehabilitated for the project which is planning to open during summer 2018.

This is an article I found online that talks about this project.....

Ferry service to Soundview should be a reality this year, and some are calling for even more service in transit-starved east Bronx waterfront communities.

The route of service that includes Soundview’s ferry stop, is scheduled to begin service later this year from Clason Point Park, and the ferry dock is now under construction, according to NYC Economic Development Corporation.

As that plan inches closer to becoming a reality, the borough president used his 2018 State of the Borough speech on Thursday, February 22 to advocate for additional ferry landings.

“Ferry service is coming to Soundview, and should come to Throggs Neck and City Island as well,” said Borough President Ruben Diaz, Jr.

Diaz’s spokesman let the quote stand without further elaboration, but in the two east Bronx communities, leaders who have long advocated for ferry service made their case for additional stops.

Robert Barbarelli, Throggs Neck Home Owners Association board member, said he believes that ferry service could come to Throggs Neck, adding that S.U.N.Y. Maritime already docks a large training vessel in Throggs Neck.

“The waterways are not used enough which I think is a reason why there are always traffic issues on our roads,” said Barbarelli. “Utilizing waterways is a faster and more scenic route to get downtown.”

Dotti Poggi, Ferry Point Community Advocates leader, said that Ferry Point Park has a parking lot that could be used for ferry customers.

“Ferry Point is a perfect place because it has already has the infrastruc­ture,” she said.

John Doyle, City Island Civic Association officer said he believes that one appropriate location for a ferry stop could be Orchard Beach, because it already has an large parking lot that is underutilized for nine months out of the year.

“Just having this mentioned in one of these speeches is helpful as this point,” said Doyle. “I am really hoping that when the Soundview ferry comes into service that it is super successful, because then we can build on that success.”

William Rivera, Community Board 9 district manager, said that the final details for the Soundview ferry are being worked out, including expanding service on the Bx 27 and Bx 39 buses by one stop during hours of operation so that commuters don’t have to walk far from the bus to ferry.

He is also involved in the planning of a community meeting in Clason Point that will take place prior to ferry operations starting.

Also being worked on are issues related to security, safety, lighting, parking, bathrooms and amenities at the Soundview ferry.

“Everyone supports the ferry, we just make sure it is done right,” said Rivera.

An EDC spokeswoman said stops along the ferry route servicing Soundview have changed in Manhattan, with an East 62nd Street stop dropped and an East 34th Street stop added.

The spokeswoman said that EDC “will begin to analyze ridership potential and landing capabilities for future expansion to other communities once we successfully implement 2018 routes this summer.”

All students are expected to read the following article, reproduced below, prior to attempting this task: Ward, M, and Chrysanthos, N 2020, ‘’Higher than usual demand’ for toilet paper in NSW supermarkets’, Sydney Morning Herald, 26 June.

'Higher than usual demand' for toilet paper in NSW supermarkets

Premier Gladys Berejiklian has asked shoppers to remain calm after reports of bare toilet paper shelves in NSW following the reinstatement of product limits in Victorian supermarkets.

Toilet paper was in short supply at Coles and Woolworths at Roselands in Sydney's south-west on Thursday, the Herald has been told.

Posting on social media, shoppers also complained of empty shelves at Coles Merrylands and Woolworths Leichhardt in Sydney, as well as Coles Toronto in Lake Macquarie.

On Wednesday afternoon Coles, Woolworths and IGA said they would reinstate product limits for toilet paper, hand sanitiser, paper towels, flour, sugar, pasta, minced meat, long-life milk, eggs and rice at all their Victorian stores.

Coles, on Friday, reintroduced one-pack purchase limits for toilet paper and paper towels across all of its stores, including Coles online.

"We ask that customers continue to shop normally so that everyone can have access to the food and groceries they need," a spokesperson said.

Costco, which has stores at Marsden Park, Crossroads and Auburn, has also reintroduced a one-per-person limit on its toilet paper packs nationwide.

It is believed the panic buying, which was witnessed earlier in the pandemic, is being caused by an uptick in coronavirus cases in Melbourne over the past week.

Victoria reported its ninth day of double-digit case growth on Thursday, with 33 new cases.

NSW Premier Gladys Berejiklian said on Friday that shoppers need to "stay calm" as there was no need for items to be stockpiled.

"Please continue to maintain your calm; continue to do what you've been doing – NSW is doing incredibly well," Ms Berejiklian said, adding that she didn't "blame" people for being concerned as product limits were reintroduced in Victoria amid an uptick in cases.

"We all have to be on our guard, but we certainly, certainly don't need to change our normal buying habits. So please continue with your normal buying habits, there's nothing to worry about."

A Woolworths spokesperson said they had seen "higher than usual" demand for toilet paper in parts of NSW, and were monitoring the situation.

“We’ve seen pockets of higher-than-usual demand for toilet roll across parts of NSW [on Thursday], but not anywhere near the levels we saw in Victoria," the spokesperson said.

"We’ll keep a close eye on demand over the coming days. We continue to ask customers to buy only what they need, as there is plenty of stock to replenish our shelves.”

(a) no restrictions are imposed by supermarkets.

(b) purchase-limit restrictions are imposed by supermarkets.

Include appropriate diagrams to illustrate your answers.

3. Suggest and explain two other ways the problem in this market could be solved. Evaluate these alternative solutions in terms of Pareto efficiency and fairness

The purpose of this assignment is to apply a waiting line model to a business service operation in order to recommend the most efficient use of time and resources. (This assignment has been adapted from Case Problem 2 in Chapter 15 of the textbook.) Use the information in the scenario provided to prepare a managerial report for Office Equipment, Inc. (OEI). Scenario Office Equipment, Inc. (OEI) leases automatic mailing machines to business customers in Fort Wayne, Indiana. The company built its success on a reputation of providing timely maintenance and repair service. Each OEI service contract states that a service technician will arrive at a customer’s business site within an average of 3 hours from the time that the customer notifies OEI of an equipment problem. Currently, OEI has 10 customers with service contracts. One service technician is responsible for handling all service calls. A statistical analysis of historical service records indicates that a customer requests a service call at an average rate of one call per 50 hours of operation. If the service technician is available when a customer calls for service, it takes the technician an average of 1 hour of travel time to reach the customer’s office and an average of 1.5 hours to complete the repair service. However, if the service technician is busy with another customer when a new customer calls for service, the technician completes the current service call and any other waiting service calls before responding to the new service call. In such cases, after the technician is free from all existing service commitments, the technician takes an average of 1 hour of travel time to reach the new customer’s office and an average of 1.5 hours to complete the repair service. The cost of the service technician is $80 per hour. The downtime cost (wait time and service time) for customers is $100 per hour. OEI is planning to expand its business. Within 1 year, OEI projects that it will have 20 customers, and within 2 years, OEI projects that it will have 30 customers. Although OEI is satisfied that one service technician can handle the 10 existing customers, management is concerned about the ability of one technician to meet the average 3-hour service call guarantee when the OEI customer base expands. In a recent planning meeting, the marketing manager made a proposal to add a second service technician when OEI reaches 20 customers and to add a third service technician when OEI reaches 30 customers. Before making a final decision, management would like an analysis of OEI service capabilities. OEI is particularly interested in meeting the average 3-hour waiting time guarantee at the lowest possible total cost. Managerial Report Develop a managerial report (1,000-1,250 words) summarizing your analysis of the OEI service capabilities. Make recommendations regarding the number of technicians to be used when OEI reaches 20 and then 30 customers, and justify your response. Include a discussion of the following issues in your report: 4. OEI is satisfied that one service technician can handle the 10 existing customers. Use a waiting line model to determine the following information: (a) probability that no customers are in the system, (b) average number of customers in the waiting line, (c) average number of customers in the system, (d) average time a customer waits until the service technician arrives, (e) average time a customer waits until the machine is back in operation, (f) probability that a customer will have to wait more than one hour for the service technician to arrive, and (g) the total cost per hour for the service operation.

7.22 LAB*: Program: Online shopping cart (Part 2)

This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program).

(1) Extend the ItemToPurchase class per the following specifications:

• Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0). (1 pt)
• Public member functions
  • SetDescription() mutator & GetDescription() accessor (2 pts)
  • PrintItemCost() - Outputs the item name followed by the quantity, price, and subtotal
  • PrintItemDescription() - Outputs the item name and description
• Private data members
  • string itemDescription - Initialized in default constructor to "none"

Ex. of PrintItemCost() output:

Bottled Water 10 @ $1 = $10

Ex. of PrintItemDescription() output:

Bottled Water: Deer Park, 12 oz.

(2) Create three new files:

• ShoppingCart.h - Class declaration
• ShoppingCart.cpp - Class definition
• main.cpp - main() function (Note: main()'s functionality differs from the warm up)

Build the ShoppingCart class with the following specifications. Note: Some can be function stubs (empty functions) initially, to be completed in later steps.

• Default constructor
• Parameterized constructor which takes the customer name and date as parameters (1 pt)
• Private data members
  • string customerName - Initialized in default constructor to "none"
  • string currentDate - Initialized in default constructor to "January 1, 2016"
  • vector < ItemToPurchase > cartItems
• Public member functions
  • GetCustomerName() accessor (1 pt)
  • GetDate() accessor (1 pt)
  • AddItem()
    • Adds an item to cartItems vector. Has parameter ItemToPurchase. Does not return anything.
  • RemoveItem()
    • Removes item from cartItems vector. Has a string (an item's name) parameter. Does not return anything.
    • If item name cannot be found, output this message: Item not found in cart. Nothing removed.
  • ModifyItem()
    • Modifies an item's description, price, and/or quantity. Has parameter ItemToPurchase. Does not return anything.
    • If item can be found (by name) in cart, check if parameter has default values for description, price, and quantity. If not, modify item in cart.
    • If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing modified.
  • GetNumItemsInCart() (2 pts)
    • Returns quantity of all items in cart. Has no parameters.
  • GetCostOfCart() (2 pts)
    • Determines and returns the total cost of items in cart. Has no parameters.
  • PrintTotal()
    • Outputs total of objects in cart.
    • If cart is empty, output this message: SHOPPING CART IS EMPTY
  • PrintDescriptions()
    • Outputs each item's description.
