  1. ManufacturingSYSTEM 11-IE-48 11-IE-59 11-IE-60

  2. Manufacturing Systems • Facilities design for manufacturing systems is extremely important because of the economic dependence of the firm. • Facility Design emphasis on

  3. There are number of factors that effect the facility planning process. • Volume of production • Variety of production • Value of each product

  4. Automatic Factory In this automation and mechanization are dominant. People perform a little number of direct task and greater number of indirect task.

  5. Fixed Automation System • Fixed automation system is influenced by the following factors, • Transfer Line • Dial Indexing Machine

  6. Fixed Automation System Transfer Line: • In this the material flow from one work station to the next in a sequential manner. • It is used for high volume production and are highly automated. • In highly automated line, the processing rates of individual machines are matched.(no buffer storage is required)

  7. Fixed Automation System When the production rates are unmatched. There are some disadvantages.

  8. Fixed Automation System • Design of Transfer Line: The processing equipment is arranged according to the processing sequence.

  9. Fixed Automation System Several Types of flow pattern are,

  10. Fixed Automation System • Dial Indexing Machine: In dial indexing machine the workstations and the input/output stations are arranged in a circular pattern. i.e. • Automated assembly systems for automotive parts. • Beverage bottling and canning process.

  11. Flexible Manufacturing System • FMS consists of a group of processing work stations/Identical machines interconnected by means of an automated material handling and storage system and controlled by integrated computer control system. • FMS is called flexible due to the reason that it is capable of processing a variety of different part styles simultaneously at the workstation and quantities of production can be adjusted in response to changing demand patterns.

  12. FMS DESCRIPTION

  13. FMS EXAMPLE

  14. Components Of FMS

  15. APPLICATION OF FMS IN MANUFACTIONSITUATIONS 1. Production of families of work-part 2.Random launching of work-part onto the system 3.Reduced Manufacturing Lead Time 4. Increased Machine Utilization 5. Reduce direct and Indirect Labour 7.Better Management Control

  16. Design requirements in mh for fms 1. Convenient access for loading/unloading 2.Random, Independent movement of palletized work-parts between workstations. 3.Temporary storage between workstations 4. Compatibility of Computer control 5. Provision of Future Expansion 6. Easily Access to Machine tool

  17. Flexibility accomplishment

  18. Characteristic of FMS

  19. Fms alternatives

  20. Single stage multi-machine system(ssms)

  21. Single stage multi-machine system(ssms)

  22. Advantages of fms • Produce a variety of Items under one roof • Produce more product more quickly • Improve efficiency • Improve product routing • Improve product quality • To reduce setup and queue times • Reduce time for product completion • Utilize human workers better

  23. Advantages of fms • Substantial pre-planning activity • Expensive, costing millions of dollars • Technological problems of exact component positioning and precise timing necessary to process a component

  24. Dis-Advantages of fms • Substantial pre-planning activity • Expensive, costing millions of dollars • Technological problems of exact component positioning and precise timing necessary to process a component

  25. Reduction of work process • Handling less is best. • Grab, Hold, and do not turn loose. • Eliminate, Combine and simplify the process. • Moving and Storing material cost should included. • Pre-position Material.

  26. Just In Time Manufacturing • History: The just in time production system was developed more than 4 decades ago by OhnoTaiichi at the Toyota motor company in japan.

  27. Definition: Just in time means having right part at the right place in the right amount at the right time in right position in right sequence and for the right cost by using right method.

  28. According to Ohno waste is divided into following seven categories. • Waste arising from over production. • Waste arising due to waiting. • Waste arising from transporting. • Waste arising from processing itself. • Waste arising from unnecessary stock on hand. • Waste arising from unnecessary motion. • Waste arising from producing defective goods.

  29. JIT Elements • We categorize JIT philosophy into five different Elements. • Visibility: • Simplicity: • Flexibility: • Standardization: • Organization:

  30. Waste: • Waste can be defined as any resource that adds cost but does not add value to the product. • Sources of wastes:

  31. JIT Impact On Facilities Design • There are many concepts and technique related to JIT production system that impact building design , facility layout and material handling system such as:

  32. Reduction of inventories: One of the main objective of JIT production system is the reduction of inventories. • By reducing inventory we obtain the following: • Space requirements are reduced by constructing smaller buildings. • Smaller loads are moved and stored. • Use of smaller and simpler storage systems, storage requirements are reduced.

  33. Deliveries to point of use: If products are purchased and produces in smaller lots, they should be delivered to the point of use to avoid stock out at the consuming process. To achieve quality at the source concept the following could be required. • Proper packaging for parts and boxes on pallets • Efficient transportation Quality at the source:

  34. Better communication and line balancing: • In JIT manufacturing system For better communication among worker U shaped production lines are used. To use the multiple abilities of the workers. To easily balance to production line using visual aids and team approach.

  35. Facilities Planning Trends Following trends can be seen: • Smaller centralized storage area • Decentralized material handling equipment • Material handling alternatives. • Visible, accessible and durable transferable containers. • Asynchronous production lines • Better handling and transportation part protection • Standard containers, Trays or Pallets.
