CASE INTERNATIONAL ARRIVALS
The U.S. Department of Transportation publishes the number of international passengers that come through U.S. airports. The busiest airports for international travel are in New York (JFK), Miami (MIA), Los Angeles (LAX), Newark (EWR), and Chicago (ORD). The most popular destinations are London (LHR), Toronto (YYZ), Tokyo (NR), Frankfurt (FRA), and Paris (CDG).
Consider the data in the following table and answer these questions:
- 1. How would you estimate the passenger volume for the coming year?
- 2. What is the role of trends and seasonality?
- 3. What other variables do you expect to influence the number of international travelers?
JFK Airport in New York, the airport with the most international travelers in the United States
JFK Airport in New York, the airport with the most international travelers in the United States

- The chairperson of the department of management at Tech wants to forecast the number of students who will enroll in operations management next semester in order to determine how many sections to schedule. The chair has accumulated the following enrollment data for the past 15 semesters: Using Exponential Smoothing with (α = 0.6) compute the forecasted number of student for semester 16 Semester Students Enrolled in OM 1 270 2 310 3 250 4 290 5 370 6 410 7 410 8 450 9 440 10 470 11 525 12 515 13 538 14 544 15 504arrow_forwardThe County Transportation Department needs to determine usage factors by day of the week for a popular toll bridge connecting different parts of the city. In the current study, they are considering only working days. Suppose that the numbers of cars using the bridge each working day over the past four weeks were (in thousands of cars) Find the seasonal factors corresponding to daily usage of the bridge.arrow_forwardChocoTown has a 4,000 square foot outlet store that serves five major customer regions, denoted A, B, C, D and E. The locations of the points representing the customer regions and their weekly demands are shown in the table below. The ChocoTown outlet store is at location (10,20). Customer Region Location Demand ($/week) A (0,10) 4,000 B (0,20) 2,000 C (20,0) 4,000 D (30,20) 3,000 E (40,10) 2,000 CandyTime is a new competitor of ChocoTown and they are considering opening a 4,000 square foot store at location (30,10). Assume the travel time from location i to j in minutes equals the straight line distance from i to j. a) Use the spatial interaction model to estimate the demand that would be captured by the new CandyTime store. Demand captured by CandyTime = ___________ b) Suppose the CandyTime store is located at (30,10), but it is not 4,000 square feet. Use the spatial interaction model to find the size in square feet for…arrow_forward
- Joburg Logistics (JL), a distributor of various products in Polokwane receives their products from suppliers in Durban, Cape Town, and Johannesburg. The company's management is concerned with the supply cost of a certain product that is supplied by a manufacturer in Durban. Currently JL has a contract with Transnet Freight Rail (TFR) for the transport of the orders from Durban. The following are the rail rate and transit time: Transit time (rail) Rail rate 5 days R2.75/unit The impact on the transport and inventory carrying cost because of this arrangement is a concern of the logistics director, Mrs Micky. As a result, Mrs Micky has requested the logistics manager to evaluate the option to use a 3PL service provider for the shipment from Durban to Johannesburg. The logistics manager has identified a certain 3PL company that has the capacity to perform this contract. However, in order to provide a transport rate, the 3PL company required the size and frequency of orders. JL currently…arrow_forwardA company that handles hazardous waste wants to minimize the shipping cost for shipments to a disposal center from five receiving stations it operates. Given the locations of the receiving stations and the volumes to be shipped daily, determine the location of the disposal center.arrow_forwardThe new software organization requires a new point of sale and stock control system for their many stores throughout Pakistan to replace their aging mini-based systems. A sales assistant will be able to process an order by entering product numbers and required quantities into the system. The system will display a description, price, and available stock. In-stock products will normally be collected immediately by the customer from the store but may be selected for delivery to the customer's home address for which there will be a charge. If stock is not available, the sales assistant will be able to create a backorder for the product from a regional warehouse. The products will then either be delivered directly from the regional warehouse to the customer's home address, or the store for collection by the customer. The system will allow products to be paid for by cash or credit card. Credit card transactions will be validated via an online card transaction system. The system will produce…arrow_forward

A high-end luxury car manufacturer sells 22,000 cars per year to four dealerships in four regions of a country. Assume 50 weeks per year. Out of this total sale, 30% of the cars are sold in North-Region, 23% are sold in East-Region, 11% are sold in West-Region, and the rest are sold in South-Region. On average there are 1,000 cars of this manufacturer in all dealerships. Out of this total inventory, 19% of the cars are in the dealership in North-Region, 30% is in East-Region, 11% is in West-Region, and the rest is in South-Region..arrow_forwardCleveland Area Rapid Delivery (CARD) operates a delivery service in the Cleveland metropolitan area. Most of CARD's business involves rapid delivery of documents and parcels between offices during the business day. CARD promotes its ability to make fast and on-time deliveries anywhere in the metropolitan area. When a customer calls with a delivery request, CARD quotes a guaranteed delivery time. The following network shows the street routes available. The numbers above each arc indicate the travel time in minutes between the two locations. Min s.t.
