    • Practice
    • Strengths / Weaknesses
    • Summary
  • What is Facility Layout Design?
    • Facility layout means planning:
      • for the location of all machines, utilities, employee workstations, customer service areas, material storage areas, aisles, restrooms, lunchrooms, internal walls, offices, and computer rooms
      • for the flow patterns of materials and people around, into, and within buildings.
    (Houseman, Slide 2)
  • Facility Layout Design – Process Layouts
    • The purpose of facility layout design is to determine the most productive way to design the layout of a building.
    • Process Layout involves three basic steps, whether the design is for a new layout or for revising an existing one:
      • (1) gather information
      • (2) develop a block plan
      • (3) design a detailed layout
    (Krajewski, 455)
  • What is Block Diagramming?
    • Block diagramming is one way to visualize the amount of movement that occurs between departments.
      • Each block represents one department of a facility.
      • Blocks can be moved around in order to minimize the distance traveled between them.
  • Using Block Diagramming in your organization
    • Block Diagramming (performed as part of a complete facility layout design) is performed infrequently.
      • The resulting layouts are usually implemented for the long-term.
      • Proper designs can lead to increased efficiency within a company.
  • Example of Block Diagramming
    • Step 1: Gather Information (Department Size)
    (Krajewski, 455) 5400 Total 700 6 800 5 1200 4 750 3 950 2 1000 1 Area Needed (ft2) Department

    • Step 1: Gather Information (Initial Layout)

  • Example of Block Diagramming (cont.)
    • Step 1: Gather Information (Trips between departments shown in interdepartmental flow matrix)

    • Step 2: Develop a block plan (Show initial traffic)

    • Step 2: Develop a block plan (Show new traffic)

  • Example of Block Diagramming (cont.)
    • Step 2: Develop a block plan (Show new layout)
    90’ 60’ (Krajewski, 458) 6 1 2 3 4 5
  • Practice
    • Create an Interdepartmental flow matrix showing the “load” between these 5 departments.
    • Create a diagram with nodes and links showing the load between departments.
    • Design a new layout showing a diagram with nodes and links showing the new optimized load between departments.

  • Practice Solution Take a few minutes to work through the above problem before continuing.
  • Practice Solution Interdepartmental flow matrix -- 5 60 -- 4 50 40 -- 3 50 150 200 -- 2 110 100 -- 1 5 4 3 2 1 Department
  • Practice Solution Current Node Diagram (of existing layout) (Suntivong, 120)
  • Practice Solution New Node Diagram (using new design) (Suntivong, 120)
  • With many nodes, it is harder to determine optimal solutions. Sometimes it is hard to give proper weight to qualitative factors. Some computer programs can quickly determine optimal solutions. Sometimes, the data is hard to gather or quantify. With correct information, layout efficiency can be improved. Weaknesses Strengths
  • Summary
    • Block diagrams can be effectively used to design facility layouts that optimizes productivity.
  • Terms to review
    • Facility Layout Design
    • Process Layout
    • Block diagramming
    • Interdepartmental flow matrix
    • Use of nodes, links, dashed lines, solid lines.
