Operations management location strategies (lecture)
- 2. Learning Objectives When you complete this chapter, you should be able to : Identify or Define: – – – – Objective of location strategy International location issues Clustering Geographic Information Systems Describe or explain: – Three methods of solving the location problem • Factor-rating method • Locational breakeven analysis • Center -of-gravity method – Describe the factors affecting location decisions
- 3. Federal Express • Stresses “hub” concept • Advantages: – enables service to more locations with fewer aircraft – enables matching of aircraft flights with package loads – reduces mishandling and delay in transit because there is total control of packages from pickup to delivery
- 4. Objective of Location Strategy Maximize the benefit of location to the firm
- 5. Industrial Location Decisions • Cost focus – Revenue varies little between locations • Location is a major cost factor – Affects shipping & production costs (e.g., labor) – Costs vary greatly between locations © 1995 Corel Corp.
- 6. Service Location Decisions • Revenue focus – Costs vary little between market areas • Location is a major revenue factor – Affects amount of customer contact – Affects volume of business
- 7. In General - Location Decisions • Long-term decisions • Difficult to reverse • Affect fixed & variable costs – Transportation cost • As much as 25% of product price – Other costs: Taxes, wages, rent etc. Objective: Maximize benefit of location to firm = Cost or Revenue = $’s! for either Manufacturing or service.

- 9. Factors That Affect Location Decisions
- 10. Factors Affecting Country • Government rules, attitudes, political risk, incentives • Culture & economy • Market location • Labor availability, attitudes, productivity, and cost • Availability of supplies, communications, energy • Exchange rates and currency risks
- 11. Region Location Decisions • Corporate desires • Attractiveness of region (culture, taxes, climate, etc.) • Labor, availability, costs, attitudes towards unions • Costs and availability of utilities • Environmental regulations of state and town • Government incentives • Proximity to raw materials & customers • Land/construction costs © 1995 Corel Corp.
- 12. Factors Affecting Site • Site size and cost • Air, rail, highway, and waterway systems • Zoning restrictions • Nearness of services/supplies needed • Environmental impact issues © 1995 Corel Corp.
- 13. Location Decision Example BMW decided to build its first major manufacturing plant outside Germany in Spartanburg, South Carolina. © 1995 Corel Corp.
- 14. Country Decision Factors • Market location – U.S. is world’s largest luxury car market – Growing (baby boomers) • Labor – Lower manufacturing labor costs • $17/hr. (U.S.) vs. $27 (Germany) – Higher labor productivity • 11 holidays (U.S.) vs. 31 (Germany) • Other – Lower shipping cost ($2,500/car less) – New plant & equipment would increase productivity (lower cost/car $2,000-3000) – Laws of U.S.A.
- 15. Transportation Model • Finds amount to be shipped from several sources to several destinations • Used primarily for industrial locations • Type of linear programming model – Objective: Minimize total production & shipping costs – Constraints • Production capacity at source (factory) • Demand requirement at destination
- 16. Components of Volume and Revenue for a Service Firm 1. Purchasing power of customer drawing area 2. Service and image compatibility with demographics of the customer drawing area 3. Competition in the area 4. Quality of the competition 5. Uniqueness of the firm’s and competitor’s locations 6. Physical qualities of facilities and neighboring businesses 7. Operating policies of the firm 8. Quality of management
- 17. Location Strategies – Service vs. Industrial Service/Retail/Professional Revenue Goods-Producing Location Focus Cost Focus Tangible costs Volume/revenue Drawing area, purchasing power Competition; advertising/pricing Physical quality Parking/access; security/ lighting; appearance/image Cost determinants Rent Management caliber Operations policies (hours, wage rates) Transportation cost of raw materials Shipment cost of finished goods Energy and utility cost; labor; raw material; taxes, etc. Intangible and future costs Attitude toward union Quality of life Education expenditures by state Quality of state and local government
- 18. Major Methods of Solving Location Problems • Weighted methods which: – Assign weights and points to various factors – Determine tangible costs – Investigate intangible costs • Center of Gravity Method – Find best distribution center location • Location breakeven methods – Special case of breakeven analysis • Transportation method – A specialized linear programming method
- 19. Telemarketing and Internet Industries • Require neither face-to-face contact with customers (or employees) nor movement of material • Presents a whole new perspective on the location problem
- 20. Geographic Information Systems • New tool to help in location analysis • Enables combination of many parameters
- 21. Final Thought The ideal location for many companies in the future will be a floating factory ship that will go from port to port, from country to country – wherever cost per unit is lowest.

- 38. Southwest Airlines • Profitable for 26 years while United, Northwest, and U.S. Air lost billions. • Strategy: Human resources – Culture of caring for people in the totality of their lives, not just at work. – Spends more to recruit and train than any other airline
- 39. Southwest Airlines • • • • • Empowered employees Wages higher than industry average Stock options for some employees Employees treated like customers Everybody understands what everybody else’s problems are • No gimmicks!
- 40. People and Work System Aspects Job Design Labor Standards
- 41. Productivity in Relation to Annual Turnover Rate >20% 16-20% 11-15% 6-10% 3-5% <3% $120,000 $125,000 $130,000 $150,000 $153,000 $200,000
- 42. Job Design • Specifying the tasks that make up a job for an individual or group • Involves determining – What is to be done (i.e., responses) – How it is to be done (i.e., tools etc.) – Why it is to be done (i.e., purpose) • Results in job description – Shows nature of job in task-related behaviors
- 43. Components of Job Design • Job specialization • Job expansion – enrichment-enlargement • Psychological components • Self-directed teams • Motivation and incentive systems • Ergonomics and work methods • Praise?
- 44. Job Expansion • Process of adding more variety to jobs • Intended to reduce boredom associated with labor specialization • Methods – – – – Job enlargement Job enrichment Job rotation Employee empowerment
- 45. Job Rotation Pediatrics Maternity © 1995 Corel Corp. © 1995 Corel Corp. © 1995 Corel Corp. Geriatrics
- 47. Psychological Components of Job Design • Individuals have values, attitudes, and emotions that affect job results – Example: Work is a social experience that affects belonging needs • Effective worker behavior comes mostly from within the individual – Scientific management argued for external financial rewards • First examined in ‘Hawthorne studies’
- 48. Self-Directed Teams • Group of empowered individuals working together for a common goal • May be organized for short-term or long-term objectives • Reasons for effectiveness – Provide employee empowerment – Provide core job characteristics – Meet psychological needs (e.g., belonging)
- 49. Motivation • Worker performance depends on – Motivation – Ability – Work environment • Motivation is the set of forces that compel behavior • Money may serve as a psychological & financial motivator
- 50. Motivation and Money • Taylor’s scientific management (1911) – Workers are motivated mainly by money – Suggested piece-rate system • Maslow’s theory (1943) – People are motivated by hierarchy of needs, which includes money • Herzberg (1959) – Money either dissatisfies or is neutral in its effect
- 51. Maslow’s Hierarchy of Needs Self-Actualization Use of abilities Self-fulfillment Ego Self Respect Social Group Interaction Job Status Safety Physical Safety Job Security Physiology Food Shelter
- 52. Ergonomics and Work Methods • Worker performance depends on – Motivation – Ability – Work environment • Foundation laid by Frederick Taylor – Match employees to task – Develop work methods – Establish work standards
- 53. Ergonomics • • • • Study of work Also called ‘human factors’ Involves human-machine interface Examples – Mouse – Keyboard
- 54. What is Work Measurement? • Determining the amount of worker time required to generate one unit of output • Provides labor standards – Target amount of time required to perform a job under normal working conditions
- 55. Uses of Labor Standards • • • • • • Costing labor content of products Planning staffing needs Cost & time estimates for bids Planning production Wage-incentive plans Employee efficiency
- 56. Sources of Labor Standards • • • • Historical experience Time studies Predetermined time standards (MTM) Work sampling
- 57. Labor Standards - Historical Experience • Labor standards are based on how many labor-hours were needed in past • Least preferred method • Advantages – Easy and inexpensive to obtain standard • Disadvantages – Unknown accuracy due to unusual occurrences, unknown pace etc.
