1. The method which usually gives a good basic feasible solution to a transportationproblem is• Northwest comer rule• Vogel's approximation method• Least Cost methodnone of the above2. In a Vogel's approximation method, row and column penalties are determined by:• Largest unit cost in each row or column.• Smallest unit cost in each row or column.• Sum of the unit costs in each row or column.• difference between the two lowest unit costs in each row and column.• difference between the two highest unit costs in each row and column.• None of these3. In northwest corner rule, we start allocation of units in the:Lower right comer of the table.• Most Middle cell of the table.• Upper right corner of the table.• Highest costly cell of the table.• Upper left-hand comer of the table.None of these

First Questions 1.Why is it that rail does not have a greater share of the freight market in the United States? 2 What is required to make cross-docking a viable solution for a logistics provider? What are the pros and cons of relocating a small or mid-sized manufacturing firm (that makes mature products) from the United States to China? 3.Jacobs and Chase (2018, pg. 379) tell us, “…, there are many techniques available for identifying potential sites for plants or other types of facilities. The process required to narrow the decision down to a particular area can vary significantly depending on the type of business and the competitive pressures that must be considered. As we have discussed, there are often many different criteria that need to be considered when selecting from the set of feasible sites.” When I worked for AT&T we closed about 12 Network Operations Centers in the U.S and built one in Denver and one in Conyers, Ga (just east of Atlanta.…
Intermodal Management is a key element to any business where the transportation of freight is critical to the organization. a. Why has the development of a global economy created the need for an effective intermodal transport system? b. The pricing of intermodal movements has based on the combination of the modes of transportation that used for the shipment. What example can you find to support the statement? c. Moving freight from one location to another presents many challenges. Give two (2) of those challenges with recommendations to reduce the impact of each one.
1. The role of the government in the transport market is to supply the transport services as required. True/False 2. Transport is viewed as derived demand. Derived demand in this context means which one of the following? a. Transport demand takes place over space and time. b. A nation’s ability and willingness to provide an adequate transport infrastructure. c. The demand for transport services is determined by the demand to transport goods and passengers from one place to another. d. An individual’s ability and willingness to buy transport services. 3. Inelastic demand means there is a substantial change in quantity demanded when another economic factor changes (typically the price of the good or service). True/False 4.

4. Companies A, B, and C supply components to three plants (F, G, and H) via two crossdocking facilities (D and E). It costs $4 to ship from D regardless of final destination and $3 to ship to E regardless of supplier. Shipping to D from A, B, and C costs $3, $4, and $5, respectively, and shipping from E to F, G, and H costs $10, $9, and $8, respectively. Suppliers A, B, and C can provide 200, 300 and 500 units respectively and plants F, G, and H need 350, 450, and 200 units respectively. Crossdock facilities D and E can handle 600 and 700 units, respectively. Logistics Manager, Aretha Franklin, had previously used "Chain of Fools" as her supply chain consulting company, but now turns to you for some solid advice. Set up the solution in Excel and solve with Solver. What are total costs?
Which of the following is NOT a method to develop an initial solution to a transportation model? - Group of answer choices - None...all are methods to develop an initial solution - northwest corner method - linear programming - intuitive least cost method
ABC supply co. The central Luzon market, which included 6 different locations, needed immediate temporary workers to meet their staffing demands due to natural calamity that passed through the country. They had never previously used a temporary staffing company locally, but due to the urgency, they needed to make a decision. The skill set, experience and education of the needed employees was a wide range and would require different recruiters to handle each. These positions included: warehouseman, general labors, clerical, purchasing, warehouse managers and inside sales. There was a time frame of 2 weeks to set up and deliver a total of 140 people in the first month. With this, what will you do as a manager to address the issue in the next two weeks? Shield your answer.

2. A company has three branches: Manila Branch, Davao Branch, and Tacloban Branch. These branches delivered the products to three distributors: X, Y, Z. The following gives the delivery costs, in thousands of pesos: From Manila Branch to X, Y, Z: 40, 50, 90 respectively; from Davao branch to X, Y, Z: 50, 80, 50 respectively; and from Visayas branch to X, Y, Z: 30, 50, 80 respectively; while The number of supplies available at each branch, and the number needed by each distributor are the following: The available supplies in the three branches: Manila, Davao, and Visayas are 400, 450, and 500, respectively. The three distributors X, Y, and Z need 600, 400 and 350 respectively. Find an optimum solution to cut down the total delivery cost.
