Facility Work Design

• Chapter 8
• Operations Management Goods, Services, and
  Value Chains, by D. A. Collier and J. R. Evans

2
Facility Layout

• Facility Layout Studies Necessary When
• New facility constructed
• Significant demand/production volume change
• New good or service in CBP
• New equipment, technology, or process
• Purpose
• Minimize delays in material handling / customer
  movement
• Maintain flexibility
• Effective labor / space utilization
• Promote employee morale / customer satisfaction
• Good housekeeping / maintenance

3
Product Layout

• based on sequence of operations during
  manufacturing or service delivery

4
Process Layout

• Functional grouping of similar activities

5
Cellular Layout

• Selfcontained groups of equipment

6
Group Layout

• Classifies parts into families

7
Facility Layout Patterns

• Fixed Layout Product (e.g., airplane) remains
  stationary processes come to product
• COMPARISON

8
Material Handling Technologies

• Industrial Trucks - Forklifts
• Conveyor Systems
• Overhead Cranes
• Automated storage retrieval systems
• Tractor-trailer systems
• Automated guided vehicles

9
Assembly Line Balancing

• Group tasks in workstations so that each
  workstation has about the same load
• EXAMPLE
• Use 1 Operator How many parts / per day can be
  produced? (1x60x8480)
• Use 3 Operators (one for each task) How many
  parts / per day can be produced?
• a) 2 x 60 x 8 960
• b) 3.33 x 60 x 8 1,600
• c) 5 x 60 x 8 2,400
• Answer Minimum of the above 960

10
Assembly Line Balancing

• EXAMPLE
• Use 2 Operators How many parts / per day can be
  produced? How to distribute the work?
• Split work equally A(.5) and B,C (.2.3.5)
• a) 2 x 60 x 8 960
• b c) 2 x 60 x 8 960
• Answer 960 and saved on idle time.
• It is now 0, for 3 operators it is 480
• Why not use 3 operators to do all a,b, and c
  (R1,440)?

11
Assembly Line Balancing

• Need 10 units/hour of 6 min/unit. How can it be
  produced? Use precedence diagram above.
• Problem cannot combine (1,2,3,4,8 4.7min) and
  (5,6,7 4.7min)
