Exam 10: Location and Layout

Malhotra Company has four distribution centers located at the location coordinates given as follows. The monthly demand at each center is also given. Management wants to build a new plant that would be located at the center of gravity of the four distribution centers. Which of the following options best represents the coordinates of new plant location? DC Coordinates Demand A (100,150) 50 B (250,250) 30 C (150,150) 15 D (200,300) 100

Facility location is the process of determining a geographic site for a firm's operations.

The point has been reached where a biotechnology research and development company must expand by building a new facility. The search has been narrowed to four locations, all of which are acceptable to management. The assessment of these sites is being made on the basis of the six subjective location factors that follow. Management has agreed to use a five- point scale (Excellent = 5, Very good = 4, Good = 3, Fair = 2, Poor = 1) to quantify and compare their subjective opinions about the relative goodness of the sites). The weight reflects the importance of each factor in the decision. Factor Evaluation by Location Location Factor Weight A B D Labor Climate 35 Exc. Very Gd. Very Gd. Exc. Quality of Life 25 Fair Good Very Gd. Poor Transportation 15 Good Very Gd. Good Fair Markets 10 Exc. Good Very Gd. Very Gd. Taxes 10 Fair Exc. Exc. Very Gd. Utilities 10 Exc. Very Gd. Good Good Calculate the weighted score for each alternative. Which location would you recommend?

Table 10.5 Union Fork, Inc. has five distribution centers located at the location coordinates given as follows. The demand at each center is also given. Coordinates Demand (2,4) 10 (6,2) 15 (4,10) 25 (13,4) 30 (10,5) 20 -Use the information in Table 10.5. What are the x- and y- coordinates for the center of gravity?

A company 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. Location Factor Weight A B C D Wages 0.40 7 5 3 5 Labor Climate 0.35 6 5 9 5 Local Regulation 0.15 3 4 3 2 Weather 0.10 2 8 6 9 Based on weighted scores, where should the company locate its new facilities?

Layout choices must be closely tied to flow strategy. Which one of the following firms is most likely to select a process layout?

A(n) _______ layout groups workstations or departments according to function.

The point has been reached where a manufacturer's research and development center must expand by building a new facility. The search has been narrowed to five locations, all of which are acceptable to management. The assessment of these sites is being made on the basis of the five subjective location factors that follow. Management has agreed to use a five- point scale (Excellent = 5, and Poor = 1) to quantify and compare their subjective opinions about the relative goodness of the sites). The weight reflects the importance of each factor in the decision.

Which location would you recommend?

Table 10.1 A single facility is needed to meet the demands of four markets. The locations and demands of these four markets are shown below. Market Coordinates Demand A (8,6) 10 B (4,12) 15 C (3,2) 10 D (9,6) 6 -Use the information from Table 10.1. If the facility must be located at one of these four markets, which of the four locations is most desirable, assuming Euclidean distance?

What types of performance criteria can be important in layout decisions? Be as complete as possible.

A(n) reflects the qualitative judgments of managers and employees, and it can be used in place of a trip matrix.

Which one of the following statements about distance measures is best?

Paced lines require that inventory storage areas be placed between stations.

A layout that groups workstations or departments according to function is referred to as a flexible- flow layout.

Table 10.14 The department of philosophy at a university in Oregon must allocate six faculty members to their new offices. The following trip matrix indicates the expected number of contacts per day made between professors. Also shown on the right is a sketch of the available office spaces (1 through 6) for the six faculty members. Assume equally sized offices. The distance between office 1 and office 2 (as well as the distance between office 1 and 3) is one unit of distance. Please measure by rectilinear distance. -Use the information in Table 10.14. Because of their academic position Professor A must be assigned to office 1, Professor C must be assigned to office 2, and professor D must be assigned to office 6. What faculty members should be assigned to offices 3, 4, and 5, respectively to minimize the total load- distance score? (Assume rectilinear distance)

A mixed- model line produces several items belonging to the same family.

Sweet Candy, Inc. wishes to open two new stores. Based on the following subjective criteria, where should the new stores be located?
