Exam 9: Location and Layout

Table 9.21 Table 7.21 The following information is given about an assembly line. The desired output rate is 90 units per hour. -Use the information in Table 9.21.Suppose that the desired output rate is increased to 120 units per hour and a solution has been found that has 4 workstations.What is the efficiency of this new assembly line?

Table 9.2 Durham Toy,Inc.has five distribution centers at the location coordinates given as follows.The monthly demand at each center is also given. -Use the information in Table 9.2.If the plant is located at A,what is the total load-distance score,assuming rectilinear distance?

One common performance criteria for layouts is capital investment.

An economic activity center is anything that consumes space.

A(n)________ gives the number of trips for some other measure of materials movement between each pair of departments per day.

A firm of four departments has the following trip matrix and current block plan of all departments: a.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. ) b.What would be the load-distance score for the following layout?

Table 9.22 The production of a particular product consists of seven work elements.The desired output rate is 60 units per hour.The work element and their precedence relationships are given. -Use the information in Table 9.22.What is the efficiency of the line created using the longest work-element time rule?

A product layout groups workstations according to function rather than arranging workstations in a linear path.

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

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

Table 9.15 Balance the following line for an output rate of 3 units per minute, using the longest work-element time rule. -Use the information in Table 9.15.What is the balance delay for your solution?

Which one of the following statements about product layout is best?

Which of the following is an advantage or characteristic of a process layout over a product layout when volumes are low?

Which one of the following statements about layout is best?

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 Calculate the weighted score for each alternative.Which location would you recommend?

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 Location Positions -Use the information from Table 9.12.What is the load-distance score if the departments were assigned as follows? (Continue assuming rectilinear distances. )

The balance delay is the amount by which efficiency falls short of 100 percent.

________ is the amount by which efficiency falls short of 100 percent.

Table 9.2 Durham Toy,Inc.has five distribution centers at the location coordinates given as follows.The monthly demand at each center is also given. -Use the information in Table 9.2.If the plant is located at the center of gravity,what is the load-distance score,assuming Euclidean distance?

Table 9.3 A firm has the following demand forecasts for the five markets that it serves: -Use the information in Table 9.3.If the firm decides to locate the warehouse at point D,what is the total load-distance score? (Use rectilinear distance).
