  1. 1. Core Functions Overlap Finance Operations Marketing
  2. 2. CORE FUNCTIONS WITHIN BUSINESS <ul><li>Operations. Responsible for… </li></ul><ul><li> Providing goods or… </li></ul><ul><li> Services </li></ul><ul><li>Marketing. Responsible for… </li></ul><ul><li> Finding or developing demand </li></ul><ul><li>Finance. Responsible for… </li></ul><ul><li> Providing for the capital </li></ul><ul><li> requirements of other functions </li></ul>
  3. 3. Inputs Transformation Customers Outputs Goods or Services Feedback The Operations Function or Production System General Characteristics
  4. 4. Job Shop Manufacture <ul><li>Contracts with customer to make products designed by the customer </li></ul><ul><li>Typically, each product’s volume is low so many different products are made (to order) </li></ul><ul><li>Requires general purpose equipment that can be used to do a broad range of operations </li></ul><ul><li>Requires employees with a wide range of skills </li></ul><ul><li>Most of inventory is Work-In-Process </li></ul>
  5. 5. MASS PRODUCTION LINES <ul><li>Low-variety, high-volume mass production </li></ul><ul><li>Uses specialized equipment (and employees) to do repetitive tasks </li></ul><ul><li>Doesn’t require employees with a high range of skills </li></ul><ul><li>WIP inventory is low since products move quickly through the line </li></ul>
  6. 6. BATCH MANUFACTURING <ul><li>Has properties of both the job shop and production line </li></ul><ul><li>Manufactures a number of products one-at-a-time (in batches) using production line approach to each batch of a particular product </li></ul><ul><li>The ability to quickly retool (‘set up’ equipment ) from one batch to another is important </li></ul>
  7. 7. Job Shop Batch Mass RECAPITULATION Low High Volume Low Variety High
  8. 8. FMS <ul><li>Flexible: Customizability, Agility </li></ul><ul><li>The buzz word for today’s manufacture is “agility” </li></ul><ul><li>System: “System is the key word </li></ul><ul><li>FMS IS A PHILOSOPHY </li></ul>
  9. 9. FLEXIBLE MANUFACTURING SYSTEM Approach Flexibility Meaning Manufacturing <ul><li>The capability of producing different parts without major retooling </li></ul><ul><li>A measure of how fast company converts its processes from making an old line of products to produce a new product </li></ul><ul><li>The ability to change a production schedule, to modify a part, or to handle multiple parts </li></ul>Operational <ul><li>The ability to efficiently produce highly customized and unique products </li></ul>Customer <ul><li>The ability to exploit various dimensions of speed of delivery </li></ul>Strategic <ul><li>The ability of a company to offer a wide variety of products to its customers </li></ul>
  10. 10. What is flexibility in manufacturing <ul><li>Basic Facilities: </li></ul><ul><li>Machine Flexibility </li></ul><ul><li>Material Handling Flexibility </li></ul><ul><li>Operation Flexibility </li></ul><ul><li>System Flexibility </li></ul><ul><li>Volume Flexibility </li></ul><ul><li>Expansion Flexibility </li></ul><ul><li>Routine Flexibility </li></ul><ul><li>Process Flexibility </li></ul><ul><li>Product Flexibility cont…. </li></ul>
  11. 11. <ul><li>Aggregate flexibility </li></ul><ul><li>Programme flexibility </li></ul><ul><li>Production flexibility </li></ul><ul><li>Market flexibility </li></ul>
  12. 12. LEVELS OF FMS <ul><li>FMM </li></ul><ul><ul><li>Flexible Manufacturing Module </li></ul></ul><ul><li>F(M/A)C </li></ul><ul><ul><li>Flexible Manufacturing (Assembly) Cell </li></ul></ul><ul><ul><li>Manufacturing Group </li></ul></ul><ul><li>FPS </li></ul><ul><ul><li>Flexible Production System </li></ul></ul><ul><li>FML </li></ul><ul><ul><li>Flexible Manufacturing Line </li></ul></ul>
  13. 13. Advantages of FMS <ul><li>Faster, lower-cost changes and better capital utilization </li></ul><ul><li>Lower direct labour cost, due to reduction in number of workers </li></ul><ul><li>Reduced inventory, due to the planning and programming precision </li></ul><ul><li>Consistent and better quality, due to automated control </li></ul><ul><li>Lower cost/unit of output, due to greater productivity using the same number of workers </li></ul><ul><li>Savings from the indirect labour, fro reduced errors of rework, repairs and rejects </li></ul>
  14. 14. Disadvantages of FMS <ul><li>Limited ability to adapt to changes in product or product mix (ex. Machines are of limited capacity and the tooling necessary for products, even of the same family, is not always feasible in a given FMS) </li></ul><ul><li>Substantial pre-planning activity </li></ul><ul><li>Expensive, costing good amount of funds </li></ul><ul><li>Technological problems of exact component positioning and precise timing necessary to process a component </li></ul><ul><li>Sophisticated manufacturing system </li></ul>
