  1. PLANT LOCATION & LAYOUT Plant location Plant layout & its types Tools and techniques for developing layout
  2. PLANT A plant is a place where Materials ' Money ' Equipment/machinery etc. are brought together for manufacturing products
  3. Necessity and Role of Plant Location prodUCt Layout Logistics Process
  4. Factors affecting Plant Location ' Nearness to Raw Material ' Transport Facilities ' Nearness to Markets ' Availability of Labour ' Availability of Fuel & Power ' Availability of Water ' Climatic conditions ' Financial & other aids Land ' Community Attitude ' Presence of related industries ' Existence of Housing facilities, Hospitals, Schools, Banks etc. ' Local bye laws, taxes ' Facilities for expansion Security
  5. PLANT LAYOUT Plant layout types Need and Factors influencing the layout Tools and techniques for developing layout - Process chart, Flow diagram, String diagram, Template and Scale models
  6. Plant Layout Plant layout means the position of the various facilities such as ' Equipment Material Manpower within the area of the site.
  7. Principles of Plant layout 1. 2. 3. 4. 5. 6. 7. Integration Minimum movements Minimum material handling Smooth and continuous flow Cubic space utilization Safe and improved environments Flexibility
  8. Types of Layout Process layout Product layout Combination layout Fixed Position layout
  9. Production volume and product variety determines type of layout product group layout layout process layout product variety
  10. Process Layout ' There is an assembly of similar operations or similar machinery in each department (for example, a drill department, a paint department, etc.) ' Advantages Wide flexibility as regards to allotment of work to equipment and workers Lesser number of machines required and better space utilization Utilize labour efficiently Eliminate bottlenecks Facilitate communication and interaction between workers and supervisors

  12. Product layout ' Product layout refers to a production system where the work stations and equipment are arranged in the sequence in which the raw material will be operated upon. ' Work is done in small amounts at each of the work stations on the line. To use the product layout, the total work to be performed must be dividable into small tasks that can be assigned to each of the workstations. ' Because the work stations each do small amounts of work, the stations utilize specific techniques and equipment tailored to the individual job they are assigned. This can lead to a higher rate of production.

  14. Combination Layout A combination of process and product layouts combines the advantages of both types of layouts. ' A combination layout is possible where an item is being made in different types and sizes. ' Here machinery is arranged in a process layout but the process grouping is then arranged in a sequence to manufacture various types and sizes of products. ' It is to be noted that the sequence of operations remains same with the variety of products and sizes.
  15. Raw Material Raw Material Product layout Combination Layout Finished Product (Gears)
  16. Fixed Position Layout ' Large products to big to move. ' In a fixed position layout, personnel, supplies, and equipment are brought to the site where the product will be assembled. ' Highly skilled workers — costly. ' Large in-process inventory
  17. product (modile) Workers Fixed Position Layout
  18. Tools and techniques for developing layout Process chart Flow diagram String diagram Template and Scale models
  19. Requirements for Plant Layout planning The information required for plant layout includes Dimensions of work places Sequence of operations Flow pattern of materials Storage space for raw materials In-process inventory Finished goods Offices, toilets, etc.
  20. Process Flow Diagrams ' It is an aid to visualize the moment of materials on an existing floor layout. ' A single line is drawn to scale on the floor plan to represent the physical movement of material through the entire plant. ' These show backtracking and excessive movement of materials and helps in relocations of plant activities to reduce travel distance.
  21. Material Movement Patterns ' The flow pattern of materials-in-process is traced and layout is built around it.
  22. Machines data card ' This card provides full information necessary for the placement and layout of equipment. ' The information generally given on these cards include facts about the machine such as capacity of the machines scape occupied power requirements handling devices required dimensions.
  23. Templates (2D) ' Template is the drawing of a machine or tool cut out from cardboard. ' Cutting to scale shows the actual space utilization. ' The template technique is an important technique because it eliminates unnecessary handlings minimize backtracking of materials it makes the mechanical handling possible it provides a visual picture of proposed or existing plan of layout at one place it offers flexibility to meet future changes in the production requirements
  24. Scale Models (3D) ' One important drawback of template technique is that it leaves the volume, depth, height and clearance of the machines to the imaginations of the reader of the drawing. ' The miniature machines and models of material handling equipment are placed in a miniature plant and moved around to find alternatives.
  25. String Diagram ' It can be defined as a scale model on which a thread is used to trace the path or movements of man and materials during a specified sequence Of events. ' A thread is used to measure distance, it is necessary that the string diagram should be drawn up to scale.
