Available capacity Expertise Quality Consideration The nature of demand Cost Slide 4: Variety How much Flexibility What degree Volume Expected output Process Selection Slide 5: Process Types Job Shops Small runs Batch Processing Repetitive/Assembly Semicontinuous Continuous Processing Projects Nonroutine jobs Slide 6: Variety, Flexibility, & Volume Slide 7: Product-Process Matrix Slide 8: Service blueprint: A method used in service design to describe and analyze a proposed service. Service Blueprint Slide 9: Establish boundaries Identify steps involved Prepare a flowchart Identify potential failure points Establish a time frame Analyze profitability Service Process Design Slide 10: Automation: Machinery that has sensing and control devices that enables it to operate Automation Slide 11: Automation Computer-aided design and manufacturing systems (CAD/CAM) Numerically controlled (NC) machines Robot Manufacturing cell Flexible manufacturing systems Computer-integrated manufacturing (CIM) Slide 12: Layout: the configuration of departments, work centers, and equipment, with particular emphasis on movement of work (customers or materials) through the system Layout Basic Layout Types : Basic Layout Types Product Layouts Process Layouts Fixed-Position Combination Layouts Basic Layout Types : Basic Layout Types Product Layout Layout that uses standardized processing operations to achieve smooth, rapid, high-volume flow Process Layout Layout that can handle varied processing requirements Fixed Position Layout Layout in which the product or project remains stationary, and workers, materials, and equipment are moved as needed Slide 15: Requires substantial investments of money and effort Involves long-term commitments Has significant impact on cost and efficiency of short-term operations Importance of Layout Decisions The Need for Layout Decisions : The Need for Layout Decisions The Need for Layout Designs (Cont’d) : The Need for Layout Designs (Cont’d) Basic Layout Formats : Basic Layout Formats Group Technology Layout Just-in-Time Layouts May be assembly-line or Group Technology formats Fixed Position Layout e.g. Shipbuilding Cellular Layouts : Cellular Layouts Cellular Manufacturing Group Technology Flexible Manufacturing Systems Cellular Layouts : Cellular Layouts Cellular Manufacturing Layout in which machines are grouped into a cell that can process items that have similar processing requirements Group Technology The grouping into part families of items with similar design or manufacturing characteristics A Flow Line for Production or Service : A Flow Line for Production or Service Flow Shop or Assembly Line Work Flow A U-Shaped Production Line : A U-Shaped Production Line Process Layout : Process Layout Slide 24: Functional Layout Cellular Manufacturing Layout : Cellular Manufacturing Layout Design Product Layouts: Line Balancing : Design Product Layouts: Line Balancing Cycle Time : Cycle Time Determine Maximum Output : Determine Maximum Output Determine the Minimum Number of Workstations Required: Efficiency : Determine the Minimum Number of Workstations Required: Efficiency Precedence Diagram : Precedence Diagram Precedence diagram: Tool used in line balancing to display elemental tasks and sequence requirements Example 1: Assembly Line Balancing : Example 1: Assembly Line Balancing Arrange tasks shown in the previous slide into workstations. Use a cycle time of 1.0 minute Assign tasks in order of the most number of followers Solution to Example 1 : Solution to Example 1 Calculate Percent Idle Time : Calculate Percent Idle Time Line Balancing Rules : Line Balancing Rules Assign tasks in order of most following tasks. Assign tasks in order of greatest positional weight. Positional weight is the sum of each task’s time and the times of all following tasks. Some Heuristic (intuitive) Rules: Solution to Example 2 : Solution to Example 2 Slide 36: Parallel Workstations Slide 37: Requirements: List of departments Projection of work flows Distance between locations Amount of money to be invested List of special considerations Designing Process Layouts Example 3: Interdepartmental Work Flows for Assigned Departments : Example 3: Interdepartmental Work Flows for Assigned Departments You do not have the permission to view this presentation.
