7 Bus 2417 Process Technology l Technology: Manual, Automated or Mental Processes that are Used to Transform Inputs Into Products and Services l Advanced Manufacturing Technology or Automation: Substitution of Machines for Human Physical and mental work. l Key to usage of automation: Repeatability l Technology: Manual, Automated or Mental Processes that are Used to Transform Inputs Into Products and Services l Advanced Manufacturing Technology or Automation: Substitution of Machines for Human Physical and mental work. l Key to usage of automation: Repeatability A task that is performed in large number of repetitions is more apt to be automated

8 Bus 2418 Automation and Operations Focus l Product Focus: High Volume Standard Products imply High Degree of Repeatability l Automation is natural l Process Focus: Low Volumes of a wide variety of product and services imply limited repeatability l Automation is more challenging l Product Focus: High Volume Standard Products imply High Degree of Repeatability l Automation is natural l Process Focus: Low Volumes of a wide variety of product and services imply limited repeatability l Automation is more challenging Line-Flow = flow-shop In the form of fixed automation

9 Bus 2419 Fixed Automation Automation of the processes and transfer of parts among stations. Characterized by: l High set up cost l Rigid Capabilities l Extreme efficiency Examples: l Assembly Lines l Transfer Lines l Process industries (e.g., petro-chemicals) Automation of the processes and transfer of parts among stations. Characterized by: l High set up cost l Rigid Capabilities l Extreme efficiency Examples: l Assembly Lines l Transfer Lines l Process industries (e.g., petro-chemicals) Sometimes referred to as Detroit type automation Machines that are linked with automatic materials handling

10 Bus 24110 An example of fixed automation: Egg processing

11 Bus 24111 Flexible Automation Automatic Processes that can be easily changed from one task to another. Characterized by: l Low set up costs l A range of capabilities l Reasonably Efficient Example: l Job Shop Automatic Processes that can be easily changed from one task to another. Characterized by: l Low set up costs l A range of capabilities l Reasonably Efficient Example: l Job Shop

12 Bus 24112 Group Technology Another Attempt to obtain the efficiency of product focus without giving up the flexibility of process focus Elements of Group Technology: l Part Families based on commonality of l Processing Steps l Part Geometry l Manufacturing Cells: Arrangement of Equipment best suited for a family Another Attempt to obtain the efficiency of product focus without giving up the flexibility of process focus Elements of Group Technology: l Part Families based on commonality of l Processing Steps l Part Geometry l Manufacturing Cells: Arrangement of Equipment best suited for a family

13 Bus 24113 Computer Integrated Manufacturing(CIM) Integration of total manufacturing enterprise through the use of integrated systems and data communications coupled with new management philosophy that improve organizational and personnel efficiency. (SME)
