 Factors That Affect Location Decisions
    Labor Productivity
    Exchange Rates and Currency Risks
    Costs
    Political Risk, Values, and Culture
    Proximity to Markets
    Proximity to Suppliers
    Proximity to Competitors (Clustering)
                Location Strategy
 One of the most important decisions a firm makes
 Increasingly global in nature
 Significant impact on fixed and variable costs
 Decisions made relatively infrequently
 The objective is to maximize the benefit of location to the firm
            Location and Costs
 Location decisions based on low cost require careful
  consideration
 Once in place, location-related costs are fixed in place
  and difficult to reduce
 Determining optimal facility location is a god
  investment
       Location and Innovation
 Cost is not always the most important aspect
  of a strategic decision
 Four key attributes when strategy is based
  on innovation
    High-quality and specialized inputs
    An environment that encourages investment
     and local rivalry
    A sophisticated local market
    Local presence of related and supporting
     industries
         Location Decisions

 Long-term decisions
 Decisions made infrequently
 Decision greatly affects both fixed and
  variable costs
 Once committed to a location, many
  resource and cost issues are difficult to
  change

                Factors That Affect
                Location Decisions
 Labor productivity
       Wage rates are not the only cost
       Lower production may increase total cost



                Labor cost per day
                                           = Cost per unit
             Production (units per day)




  $70                                         $25
         = $1.17 per unit                            = $1.25 per unit
60 units                                    20 units
              Factors That Affect
              Location Decisions
 Exchange rates and currency risks
     Can have a significant impact on cost structure
     Rates change over time

 Costs
     Tangible - easily measured costs such as utilities, labor,
      materials, taxes
     Intangible - less easy to quantify and include education, public
      transportation, community, quality-of-life
               Factors That Affect
               Location Decisions
 Political risk, values, and culture
     National, state, local governments attitudes toward private and
      intellectual property, zoning, pollution, employment stability may
      be in flux
     Worker attitudes towards turnover, unions, absenteeism
     Globally cultures have different attitudes towards punctuality,
      legal, and ethical issues
              Factors That Affect
              Location Decisions
 Proximity to markets
     Very important to services
     JIT systems or high transportation costs may make it important to
      manufacturers

 Proximity to suppliers
     Perishable goods, high transportation costs, bulky products
               Factors That Affect
               Location Decisions

 Proximity to competitors
     Called clustering
     Often driven by resources such as natural, information, capital,
      talent
     Found in both manufacturing and service industries
         Service Location Strategy
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 competitors’ locations
6. Physical qualities of facilities and neighboring businesses
7. Operating policies of the firm
8. Quality of management
    How Hotel Chains Select Sites
 Location is a strategically important decision in
  the hospitality industry
 La Quinta started with 35 independent
  variables and worked to refine a regression
  model to predict profitability
 The final model had only four variables
     Price of the inn
     Median income levels
     State population per inn
     Location of nearby colleges
      The Call Center Industry

 Requires neither face-to-face contact nor
  movement of materials
 Has very broad location options
 Traditional variables are no longer
  relevant
 Cost and availability of labor may drive
  location decisions
          Layout Design

       Strategic Importance of
          Layout Decisions:

 The objective of layout strategy is to
develop a cost-effective layout that will
   meet a firm’s competitive needs
  Layout Design Considerations

 Higher utilization of space, equipment, and
  people
 Improved flow of information, materials, or
  people
 Improved employee morale and safer working
  conditions
 Improved customer/client interaction
 Flexibility
      Types of Layout
1. Office layout
2. Retail layout
3. Warehouse layout
4. Fixed-position layout
5. Process-oriented layout
6. Work-cell layout
7. Product-oriented layout
            Types of Layout
1. Office layout: Positions workers, their
   equipment, and spaces/offices to provide
   for movement of information
2. Retail layout: Allocates shelf space and
   responds to customer behavior
3. Warehouse layout: Addresses trade-offs
   between space and material handling
            Types of Layout
4. Fixed-position layout: Addresses the layout
   requirements of large, bulky projects such
   as ships and buildings
5. Process-oriented layout: Deals with low-
   volume, high-variety production (also
   called job shop or intermittent production)
            Types of Layout
6. Work cell layout: Arranges machinery and
   equipment to focus on production of a
   single product or group of related products
7. Product-oriented layout: Seeks the best
   personnel and machine utilizations in
   repetitive or continuous production
         Good Layouts Consider
1.   Material handling equipment
2.   Capacity and space requirements
3.   Environment and aesthetics
4.   Flows of information
5.   Cost of moving between various work areas
             Office Layout
 Grouping of workers, their equipment, and
  spaces to provide comfort, safety, and
  movement of information
 Movement of
  information is main
  distinction
 Typically in state of
  flux due to frequent
  technological
  changes
  Supermarket Retail Layout

 Objective is to maximize profitability
  per square foot of floor space
 Sales and profitability vary directly
  with customer exposure
Five Helpful Ideas for Supermarket
               Layout
1. Locate high-draw items around the periphery of
   the store
2. Use prominent locations for high-impulse and
   high-margin items
3. Distribute power items to both sides of an aisle
   and disperse them to increase viewing of other
   items
4. Use end-aisle locations
5. Convey mission of store through careful
   positioning of lead-off department
Store Layout
              Retail Slotting
 Manufacturers pay fees to retailers to get
  the retailers to display (slot) their product
 Contributing factors
     Limited shelf space
     An increasing number of new products
     Better information about sales through POS
      data collection
     Closer control of inventory

Warehousing and Storage Layouts

 Objective is to optimize trade-offs
  between handling costs and costs
  associated with warehouse space
 Maximize the total “cube” of the
  warehouse – utilize its full volume while
  maintaining low material handling costs
 Warehousing and Storage Layouts

Material Handling Costs
 All costs associated with the transaction
     Incoming transport
     Storage
     Finding and moving material
     Outgoing transport
     Equipment, people, material, supervision, insurance, depreciation

 Minimize damage and spoilage
 Warehousing and Storage Layouts

 Warehouse density tends to vary inversely with
  the number of different items stored
 Automated Storage and
  Retrieval Systems (ASRSs)
  can significantly improve
  warehouse productivity by
  an estimated 500%
 Dock location is a key
  design element
                 Random Stocking
 Typically requires automatic identification
  systems (AISs) and effective information systems
 Random assignment of stocking locations allows
  more efficient use of space
 Key tasks
    1.   Maintain list of open locations
    2.   Maintain accurate records
    3.   Sequence items to minimize travel, pick time
    4.   Combine picking orders
    5.   Assign classes of items to particular areas

                                                         Office
                         Shipping and receiving docks
         Fixed-Position Layout
 Product remains in one place
 Workers and equipment come to site
 Complicating factors
    Limited space at site
    Different materials
     required at different
     stages of the project
    Volume of materials
     needed is dynamic
        Alternative Strategy
 As much of the project as possible is
  completed off-site in a product-oriented
  facility
 This can
  significantly
  improve efficiency
  but is only
  possible when
  multiple similar
  units need to be created
    Process-Oriented Layout

 Like machines and equipment are
  grouped together
 Flexible and capable of handling a wide
  variety of products or services
 Scheduling can be difficult and setup,
  material handling, and labor costs can
  be high

    Process-Oriented Layout

 Arrange work centers so as to minimize
  the costs of material handling
 Basic cost elements are
    Number of loads (or people) moving
     between centers
    Distance loads (or people) move between
     centers
          Computer Software
 Three dimensional visualization software
  allows managers to view possible layouts
  and assess process, material
  handling,
  efficiency,
  and safety
  issues
               Work Cells
 Reorganizes people and machines into
  groups to focus on single products or
  product groups
 Group technology identifies products that
  have similar characteristics for particular
  cells
 Volume must justify cells
 Cells can be reconfigured as designs or
  volume changes
   Advantages of Work Cells
1. Reduced work-in-process inventory
2. Less floor space required
3. Reduced raw material and finished goods
   inventory
4. Reduced direct labor
5. Heightened sense of employee
   participation
6. Increased use of equipment and
   machinery
7. Reduced investment in machinery and
   equipment
Improving Layouts Using Work
            Cells



Current layout - workers in
small closed areas. Cannot
increase output without a third
worker and third set of
equipment.                        Improved layout - cross-trained workers
                                  can assist each other. May be able to
                                  add a third worker as additional output
                                  is needed.
Improving Layouts Using Work
            Cells



 Current layout - straight lines
 make it hard to balance tasks             Improved layout - in U shape,
 because work may not be divided           workers have better access.
 evenly                                    Four cross-trained workers were
                                           reduced.


                    U-shaped line may reduce employee movement and
                    space requirements while enhancing communication,
                    reducing the number of workers, and facilitating
                    inspection
   Requirements of Work Cells

1. Identification of families of products
2. A high level of training, flexibility and
   empowerment of employees
3. Being self-contained, with its own
   equipment and resources
4. Test (poka-yoke) at each station in the cell
Repetitive and Product-Oriented
             Layout
Organized around products or families of similar
high-volume, low-variety products
1.   Volume is adequate for high equipment utilization
2.   Product demand is stable enough to justify high investment in specialized
     equipment
3.   Product is standardized or approaching a phase of life cycle that justifies
     investment
4.   Supplies of raw materials and components are adequate and of uniform
     quality
         Product-Oriented Layouts
 Fabrication line
      Builds components on a series of machines
      Machine-paced
      Require mechanical or engineering changes to balance
 Assembly line
      Puts fabricated parts together at a series of workstations
      Paced by work tasks
      Balanced by moving tasks




Both types of lines must be balanced so that the time to perform the work at
each station is the same
        Product-Oriented Layouts
Advantages
   1.    Low variable cost per unit
   2.    Low material handling costs
   3.    Reduced work-in-process inventories
   4.    Easier training and supervision
   5.    Rapid throughput



Disadvantages
   1.    High volume is required
   2.    Work stoppage at any point ties up the whole operation
   3.    Lack of flexibility in product or production rates

  industry in
  the US
         Assembly-Line Balancing
 Objective is to minimize the imbalance
  between machines or personnel while
  meeting required output
 Starts with the precedence relationships
    1.   Determine cycle time
    2.   Calculate theoretical
         minimum number of
         workstations
    3.   Balance the line by
         assigning specific
         tasks to workstations
