K Layout
1. Step 1: Gather Information
1. Space requirements
2. Closeness factors
3. Constraints
2. Step 2: Develop a Block Plan
Look for ways of revising block plan so departments with highest closeness ratings are located
close together.
1. Weighted-distance method
a. Distance measures
• Euclidean distance
• Rectilinear distance
2. Application K.1: Distance Measures
What is the rectilinear distance between (20, 10) and (80, 60)?
=−+−= BABAAB yyxxd
3. Calculate weighted-distance score for a layout. Example using OM Explorer:
4. Application K2: Developing Layout
Matthews and Novak Design Company has been asked to design the layout for a
newly constructed office building of one of its clients. The closeness matrix showing
the daily trips between its six department offices is given below.

Shown below on the right is a block plan that has been suggested for the building
(original plan). A partially completed table is shown to the left, assuming rectilinear
distance. Complete the table.

3. Step 3: Design a Detailed Layout
• Translate block design into a detailed representation
• More exact sizes, shapes, and detail; show aisles, stairs, machines, desks, and the like.
