Question 1

right side of the square

Answer 1

flow rate : how many outputs per hour

Question 1

left side of the square

Answer 1

order of the diagram

Question 2

bottom side of the square

Answer 2

cycle time : how long 1input spends in the activity

Question 3

facility design and layout

Answer 3

finding the best arrangements of the physical components within the time, cost, and technology constraints (layout is the arrangement of the service delivery system)

Question 4

objectives of designing a good layout

Answer 4

• minimize the movement of object –> higher efficiency
• high utilization of space but balanced with the possibility of expansion
• flexibility for rearrangements
• convenience for customers
• satisfactory physical environment for workers
• attractive appearence

Question 5

process flowchart definition

Answer 5

visual aid to identify opportunities for improvement in process efficiency

Question 6

4 steps of process flow analysis

Answer 6

1. diagram a process
2. identify bottleneck operations
3. determine system capacity
4. make improvements

Question 7

methods for process flow improvement

Answer 7

1. identify bottlenecks
2. division of labor and job rotation (combine the bottleneck with others –> reallocate resources for sharing workload)
3. use technology
4. introduce self service

Question 8

environmental orientation considerations

Answer 8

• spatial cues to orient visitors
• entrance atrium –> customers gain a quick orientation
• orientation signs and aids –> ensure a smooth flow of traffic
• formula facility –> remove the customers’ anxiety of disorientation

Question 9

process layout

Answer 9

• allows customers to create their own sequence of service activities (some degree of customization)
• possible number of layouts = n!
• operations sequence analysis –> minimize the total traveling distance and flow amount

Question 10

CRAFT

Answer 10

Computerized Relative Allocation of Facilities Technique
