Figure K.6
The Deans' Suite
The College of Business allocates some leftover funds for a complete remodel of the deans' suite. The
project, titled "Use It or Lose It" has a number of objectives, one of which is to place departments or areas
which have the greatest demand closest to each other as to minimize the total travel. Maintenance
completely guts the top floor of the college and identifies 9 natural room locations within this space.
These room locations are flexible, meaning that any one of them could be turned into an office, lounge, or
other use. The room at the upper left of the grid has windows on two walls and has been claimed by the
dean. The occupants of the deans' suite and their frequency of interaction is shown in the table.

The layout of this new great space is shown in the graph. Each square represents 15' × 15' and thus their
midpoints could be considered to be 15' apart if adjacent in a row or column. Adjacent diagonal rooms
can be calculated as 21' apart.

32) A department store chain is designing a layout for a new store. The store manager wants to provide as
much convenience as possible for her customers. Based on historical data, the number of trips between
departments per hour is given in the following closeness matrix. A block plan showing a preliminary
layout is also shown.
Customer travel between departments is restricted to the aisles shown in the block plan as dotted lines.

K.3 Step 3: Design a Detailed Layout
1) A detailed visual representation of the block plan helps decision-makers discuss the proposal and
problems that might be otherwise overlooked, particularly when evaluating high customer-contact
processes.
2) Detailed layouts can be two-dimensional drawings, three-dimensional models, or computer-aided
graphics.
3) Describe what is depicted in the visual representation of the detailed layout.
