          11.8 Summary

              Facility planning involves decisions about the functional layout and physical arrangement
               of economic activity centers.
              Every layout has four fundamental elements which are Planning Units (SPUs), Affinities,
               Space and Constraints.

              The four basic types of layouts are Process layout, Product layout, Fixed layout and Group
               layout.
              In process layouts, one of the principles of paramount importance is that centers between
               which frequent trips or interactions are required should be placed close to one another.
              A number of computerized layout programs have been developed since the 1970s to help
               devise good process layouts.
              A  product layout is also called a line layout.  In this type of arrangement, the various
               facilities, such as machine, equipment, work force, etc., are located based on the sequence
               of operation on parts.
              Fixed Position Layout is essential when the products are difficult to move.

              Cellular or group layout is suitable when a large variety of products are needed in small
               volumes.
              Plant layout is as well applicable to five star hotels  and to a cinema hall, where emphasis
               is on comfort, and convenience.
              Product layout and process layout represent the two extremes of layout techniques.

          11.9 Keywords

          A Fixed Layout: It is a layout where the material remains at a fixed position and tools, machinery
          and men are brought to the location of the material.
          A Product Layout: In this type of arrangement, the various facilities, such as machine, equipment,
          work force, etc., are located based on the sequence of operation on parts.

          Cellular Layout: It is a layout based on group technology principles. It is a combination of both
          process and product layout and incorporates the strong points of both of these.
          Computerized Relative Allocation of Facilities Technique (CRAFT): A method uses a load matrix,
          distance matrix, and cost per unit distance traveled as initial inputs and then tries to improve the
          relative placement of the departments as measured  by total  material handling  cost for  the
          layout.
          Facility Planning: It offers real added value improvements to the organization’s core business
          at four levels; Site Location, Site Planning, Facility and Building Layout and Workstation Design.
