Production & operation mgt

  1. 1. Manufacturing System Any manufacturing organisation can be termed as a production system to produce goods & services. Three main components: Inputs : labour, raw materials, bequipments financial resources etc.
  2. 2. Manufacturing System <ul><li>Transformation process : inspection, mechanical process , control, etc. </li></ul><ul><li>Out put :- product </li></ul>
  3. 3. Manufacturing System <ul><li>Production is the process by Which goods </li></ul><ul><li>And services are created . </li></ul><ul><li>The conversion process can be categorise by the following activities </li></ul><ul><li>Receipt and storage of raw material </li></ul><ul><li>transportation </li></ul>
  4. 4. Manufacturing System <ul><li>3 Inspection </li></ul><ul><li>4 storage </li></ul><ul><li>It can be classified into two categories </li></ul><ul><li>Intermittent System </li></ul><ul><li>Continuous system </li></ul>
  5. 5. Intermittent system <ul><li>The goods are manufactured to fulfill orders made by customers rather than for stock. </li></ul><ul><li>Here flow of material is intermittent </li></ul><ul><li>Characteristics:- </li></ul><ul><li>1. Most products are produced in small quantities </li></ul>
  6. 6. Intermittent system <ul><li>2. Machines and equipment are laid out by process. </li></ul><ul><li>3. Work loads are generally unbalanced. </li></ul><ul><li>4.Highly skilled operators are required for efficient use of machine and equipment. </li></ul><ul><li>5. In-process inventory is large </li></ul><ul><li>6. Flexible to suit production varieties. </li></ul>
  7. 7. Intermittent system <ul><li>It can be further classified into two categories. </li></ul><ul><li>Job production </li></ul><ul><li>& </li></ul><ul><li>Batch production </li></ul>
  8. 8. Job production <ul><li>Job order process can be characterized by : </li></ul><ul><li>Whole project is taken as a single operation. </li></ul><ul><li>2. Work is to be completed on each product before processing the next item </li></ul><ul><li>3. Versatile and skilled labour is needed </li></ul><ul><li>4. High capital investment </li></ul><ul><li>5. Control operations are relatively simple </li></ul>
  9. 9.

Mass Production 2. Process Production </li></ul>
  11. 11. Mass production <ul><li>Here items are produced In large quantities and emphasis is given to stock not to order. </li></ul><ul><li>It is generally used for assemblies or components of an items </li></ul>
  12. 12. Process production <ul><li>Here more emphasis is given on the automation of production process </li></ul><ul><li>The volume of production is very high </li></ul><ul><li>Example petroleum products, chemical products etc. </li></ul>
