Exam 9: Location and Layout

A company that assembles big airplanes or locomotives is likely to have which of the following layouts?

The absolute location is the placement of the center relative to other centers.

A(n)________ line is a product line that produces several items belonging to the same family.

Table 9.23 The Terminal Company is attempting to balance its assembly line of high-voltage electrical connectors. The desired output for the line is 50 connectors per hour, and the information on the work elements for this assembly line is as follows. Work Elements Time (sec) Immediate Predecessor(s) 40 -\cdot 36 20 2 30 , 34 35 5 15 , 40 38 ,, -Use the information from Table 9.23,and the longest work-element rule to balance this line.If the time needed to perform work element K was reduced by 1 second and all other work element times were unchanged,what would happen to the number of stations needed to balance the line?

One dominant factor in locating service facilities is customer proximity.

Table 9.12 A company with a process layout wants to rearrange its facility in the space available. There are six departments, and the flow among them is given in the following trip matrix. The shape and the size of the space available is also given. Assume rectilinear distances. Trips Between Departments - 8 3 0 9 6 - 0 8 0 0 - 0 8 9 - 0 3 - 3 - Location Positions 1 2 3 4 5 6 -Use the information from Table 9.12.Consideration of safety and EPA regulations restrict the location of certain departments: Department A must be assigned to positions 1 or 4,Department D must be assigned to positions 4 or 6,Department E must be assigned to positions 1 or 3,and Department F must be assigned to positions 3 or 6.What is the least load-distance assignment of the departments to locations?

Many projects use a fixed-position layout.

________ is the assignment of work to stations in a line so as to achieve the desired output rate with the smallest number of workstations.

Line balancing is the assignment of work to stations in a line so as to achieve the desired output rate with the smallest number of workstations.

When volumes are high,generally an advantage of ________ layouts relative to ________ layouts is less unproductive time is lost to changeovers and material handling.

One of the advantages of building a new plant or moving to a new retail or office space is that the firm does not have to rely on production from a single plant.

Table 9.11 A company of four departments has the following trip matrix and current locations of all departments: Trips Between Departments - 18 0 25 - 30 0 - 12 - Current Layout A B C D -Use the information in Table 9.11.What is the load-distance score for the current layout? (Assume rectilinear distance and that the distance between departments A and B is one unit of distance.)

Table 9.8 The Neale Company has four distribution centers (A, B, C, and D) that require monthly shipments of 30,000, 24,000, 36,000, and 24,000 gallons of diesel fuel per month, respectively. Three wholesalers (1, 2, and 3) are willing to supply up to 36,000, 48,000 and 30,000 gallons, respectively. Total costs (in $) for both shipping and price follow. A blank transportation method tableau is provided below. Distribution Center Wholesaler 1 2.2 2.0 2.0 2.0 2 1.9 2.3 2.0 2.2 3 2.3 1.9 2.3 2.0 -Use the information in Table 9.8.What can be said about a plan that ships 18,000 gallons from 1 to C; 18,000 gallons from 1 to D; 30,000 gallons from 2 to A; 18,000 gallons from 2 to C; 24,000 gallons from 3 to B; and 30,000 from 3 to D?

Relative to ________ layouts,________ layouts have the potential disadvantage of lost productive time in changing from one product or service to another.

Table 9.19 The Illinois Appliance Company is installing a line to produce a vacuum cleaner, and you, as the operations manager, are responsible for designing the line. The line has to produce 30 units per hour. The work elements to be performed are as follows, with the time needed and immediate predecessor(s) also shown. Work Element Time (sec) Immediate Predecessor(s) 55 -- B 45 25 20 40 50 70 45 , 20 80 , -Use the information in Table 9.19.If you balance the line using the longest work-element time rule,which elements are assigned to station 2?

A line-flow layout is an arrangement where the product is fixed in place,while workers,along with their tools and equipment,come to the product to work on it.

Which of the following statements about performance criteria relative to layouts is NOT generally true?

A company has determined the "demand points" and their relative locations as follows: Demand Points X-Coordinate Y-Coordinate Load A 12 15 1000 B 22 9 450 C 16 14 750 D 14 15 550 a.If a company desires to locate a manufacturing facility at the center of gravity,what would be the x- and y-coordinates of the facility? b.If a facility were to be located at (15,15),what would be the load-distance score? (Assume rectilinear distance) c.If a facility were to be located at (15,15),what would be the load-distance score? (Assume Euclidean distance)

Explain what line balancing is and how the technique is used as part of designing flexible-flow layouts.

Table 9.23 The Terminal Company is attempting to balance its assembly line of high-voltage electrical connectors. The desired output for the line is 50 connectors per hour, and the information on the work elements for this assembly line is as follows. Work Elements Time (sec) Immediate Predecessor(s) 40 -\cdot 36 20 2 30 , 34 35 5 15 , 40 38 ,, -Use the information from Table 9.23,and the longest work-element rule to balance this line.What is the idle time for the third station?
