Dimensionless Block Diagram
The dimensionless block diagram is the first
layout attempt and the result of the activity
relationship chart and the worksheet. Even
though this layout is dimensionless, it will be
the basis for the master layout and plot plan.

Dimensionless Block Diagram
Cut up a piece of paper into about 2 x 2
squares. Indicate the activity number and place
the relationship codes in the positions indicated
below.

Dimensionless Block Diagram
Once the pieces are ready, arrange the components
in order to satisfy as many activity codes as
possible. Arrange the A codes first (full side
touching), E codes next (at least one corner
touching), and so on. No X relationships
should be touching. Grade your solution. . .the
fewer number of checks, the better.

Activity Relationship Analysis

1. The activity relationship diagram
2. The worksheet
3. The dimensionless block diagram
4. The flow analysis

Flow Analysis
Flow analysis is now performed on the
dimensionless block diagram. Starting with
receiving (5), show the movement of materials to
stores (6), fabrication (1), welding (2), paint
(3), assembly and packing (4), warehouse (7), and
to shipping (8). Material should flow through
the facility and not skip areas. Additionally,
shipping and receiving should not be in the
middle of the building.

Engineered Planning Approach

• Computer-Aided Software
• CRAFT (computerized relative allocation of
  facilities)
• ALDEP (automated layout design program)
• CORELAP (computerized relationship layout
  planning)

Benefits Pitfalls

• Visual representation
• Easy to understand
• Rational explanation
• Reduced nonvalue activities
• Inventory reduction

• Focused on material transport issues
• Dynamic systems
• Relationships are usually omitted
