Productivity is best served by an efficientflow of the elements that move throughthe facility.

A primary objective in planning anefficient enterprise is to provide for element flows that will facilitate theefficient movement of the elementsthrough the activities

The material flow pattern becomes thefoundation for not only the basic designof the facility, but for the overallefficiency of the entire operation.The overall success of an enterprise or at least its profitability, is a directreflection of the effort that goes into theflow planning

Advantages of planned materialflow:1. Increased efficiency of production,

productivity2. Better utilization of floor space3. Simplified handling activities4. Better equipment utilization, less idle time5. Reduced in-process time6. Reduced in-process inventory7. More efficient utilization of work force8. Reduced product damage9. Minimal accident hazards

10. Reduced walking distances11. Reduced traffic congestion in aisles12. Basis for an efficient layout13. Easier supervision14. Simplified production control15. Minimal back-tracking16. Smooth production flow17. Improved scheduling process

18. Reduced crowded condition19. Better housekeeping20. Logical work sequece

Factors for consideration in PMF:

1. Material or product: characteristics,volume of production, number of different parts, number of operations,storage requirements

2. Moves: frequency, speed, volume,scope, area, distances, sources,destinations, cross traffic, required flowbetween work areas, location of receiving and shipping

3. Handling methods: unit handled, possibleuse of gravity, MH principles, desiredflexibility, equipment required, possiblealternatives, preliminary MH plans.

4. Process: type, sequence of operations,possibility of performing during move,specific requirements of activities,

product vs. process layout, quantity of equipment, space requirements, number of sub-assemblies

5. Building: size, shape, type, number of floor, location of doors, location of columns, aisle width or location, ceilingheight, desired location of department

6. Site: topography, transportation facilities,expansion possibilities7. Personnel: number, movement, safety,

working conditions, supervisoryrequirements
