Exam 13: Supply Chain Logistic Networks

Acme Fasteners desires to locate a new facility.Based on preliminary analysis,the choice has been reduced to four locations: A,B,C,and D.These four locations were rated on a scale from 1 (worst)to 10 (best)on each of four criteria.Each criterion was also weighted to indicate its importance (i.e. ,the higher the weight,the more important).The list of ratings and weights follows. Based on weighted scores,where should Acme locate its new facility?

Table 13.6 Union Fork,Inc.has five distribution centers located at the location coordinates given as follows.The demand at each center is also given. -Use the information in Table 13.6.What are the x and y coordinates for the center of gravity?

On average,it is less expensive to relocate a service-oriented business than a manufacturing business.

Forward placement is a reduction in inventory and safety stock because of the merging of variable demands from customers.

When using Geographical Information System (GIS)tools to solve multiple-facility location problems,an analyst may also use load-distance scores and center of gravity data to arrive at trial locations.

Table 13.1 Four departments are located in adjacent bays in the same loading dock.The distance between adjacent bays is 30 feet,the distance between bays separated by another (Alpha and Charlie,Bravo and Delta)is 60 feet,and the distance between Alpha and Delta is 90 feet.Material flows (loads)between departments are shown in the Table below. -Use the information from Table 13.1.Calculate the total load distance for this layout.

When using the load-distance method to select a new location,the decision maker can represent the number of trips to be made,the number of customers needing a physical presence,or number of tons per week,among other measures,as loads.

Table 13.4 Royal Flush Plumbing Supplies has the following demand forecasts for the five markets that it serves: -Use the information in Table 13.4.What is the center of gravity?

What are the components and capabilities of a geographical information system?

Widgets,Inc.wishes to locate two new manufacturing facilities.Based on the following subjective criteria,where should the new facilities be located? (Excellent = 5,Very good = 4,Good = 3,Fair = 2,Poor = 1)

A grower and shipper of fresh gourmet herbs has determined the following demand forecast for the five metropolitan markets that the firm serves.Based on your calculations of the center of gravity,where should the new herb farm be located?

Table 13.10 Sagebrush Company has four warehouses (A,B,C,and D)that require monthly shipments of 250,200,300,and 200 units per month,respectively.Its three plants (1,2,and 3)have monthly capacities of 300,400,and 450,respectively.Plant capacities,warehouse needs and shipping costs (in $)are shown in the following initial transportation method tableau.For example,the shipping cost from Plant 1 to Warehouse A is $17 per unit.A second table showing POM for Windows results from running this transportation problem is shown below the tableau. -Use the information in Table 13.10.Which of the following statements is FALSE?

Discuss the trade-offs with locating the inventory at the factory versus locating it closer to the customer at a warehouse,distribution center,wholesaler,or retailers.

Consider the transportation tableau shown below.What is the minimum cost of transporting the production from Ada,Bugtussle,and Choctaw to Durant,Edmond,and Foss if costs per unit are shown at the intersections of each location?

The Dhaba Restaurant wishes to locate a new facility.Based on the following subjective criteria,where should the new facility be located? (Very good = 5,Good = 4,Fair = 3,Poor = 2,and Very poor = 1)

Service location decisions are driven primarily by the operating costs at the locations under consideration.

Each cell in the interior of a transportation tableau not in the requirements row or capacity column is a(n)________.

Geographical Information System (GIS)tools are useful in solving single-facility location problems,but because of software limitations,cannot be used for determining multiple-facility locations.

The center of gravity technique does not take into consideration the:

A(n)________ is a standard matrix that is used to solve location problems using the transportation method.
