Introduction

  • Overview of flow, space, and activity relationship in facilities management.

1. Flow

  • Definition: The movement of elements from sources to delivery points within facilities and through distribution channels to customers.
  • Factors Influencing Flow:
    • Lot size
    • Unit load size
    • Material handling equipment and strategies
    • Layout arrangement
    • Building configuration
  • Flow Types: Includes flow of materials, personnel, equipment, information, money, etc.
  • Analysis: Involves flow patterns, measuring flow, and graphical analysis.

2. Space

  • Definition: Area required for production systems, storage, inventories, handling equipment.
  • Factors Influencing Space Requirements:
    • Lot size and storage systems
    • Production equipment type and size
    • Material handling equipment
    • Layout arrangement and building configuration
    • Housekeeping and organizational policies
    • Design of offices, cafeterias, and restrooms
  • Considerations: Determining workstation specifications, department specifications, and other space requirements.

3. Activity Relationships

  • Definition: Relationships between production activities, services, and service interactions.
  • Key Elements:
    • Material or personal flow
    • Environmental considerations
    • Organizational structure
    • Continuous improvement methodologies (e.g., teamwork)
    • Control issues
    • Process requirements
  • Importance: Crucial for facilities design and planning.

4. Flow Systems

  • Types of Flow: Discrete vs. continuous processes.
  • Categories of Flow Systems:
    • Materials management system
    • Material flow system
    • Physical distribution system (Logistics system)
Flow Processes
  • Materials Management: Involves managing flow into the manufacturing facility including inventory tracking, production forecasts, and communication.
  • Material Flow System: Manages flow within facilities, including operations related to warehouses and manufacturing departments.
  • Physical Distribution System: Manages flow from the facility to customers, involving shipping and logistical considerations.

5. Material Flow Systems

  • Principles:
    • Minimize total flow by eliminating unnecessary movement.
    • Reduce manual handling by mechanizing or automating flow.
    • Optimize flow through planning.
  • Flow Pattern Types:
    • Simultaneous, coordinated, and natural movement in workstations.
    • Variations depend on department type (product vs. process).

6. Flow Patterns

  • Within Workstations:
    • Importance of motion studies and ergonomics for efficiency.
    • Flow should exhibit characteristics like synchronous, natural, and rhythmic movement.
  • Within Departments:
    • Patterns depend on department type; minimal flow should occur between workstations.
  • Between Departments: Evaluates overall flow within facilities.
Flow Types Between Departments
  • Patterns: Straight-line, U-shape, circular, etc.
  • Criteria: Evaluate flow considering entrance and exit locations.

7. Flow Planning

  • Effective Flow Characteristics:
    • Start at receiving, end at shipping.
    • Minimize backtracking and direct flows.
    • Ensure ease of expansion for new processes.

8. Measuring Flow

  • Quantitative Measures: Includes distances traveled and volumes of materials.
  • Qualitative Measures: Focus on communication and organizational interactions.

9. Departmental Planning

  • Classification Based on Volume-Variety:
    • Product layout for high volume.
    • Process layout for low variety, high volume.
    • Fixed location for specific machinery.

10. Designing Manufacturing Cells

  • Cellular Manufacturing: Groups similar parts into families for efficiency.
  • Direct Clustering Algorithm (DCA): A procedural guide for forming manufacturing cells based on part requirements and machine capabilities.

11. Space Requirements

  • Factors Influencing Space Determination:
    • Historical data for estimating future requirements.
    • Methods for determining needs: production-center method, converting method, rough layout, space-standards method, and ratio trend method.
  • Workstation and Department Space:
    • Requirements for equipment, materials, and personnel must be carefully calculated.

12. Visual Management and Space Requirements

  • Proper design of workspaces and aisles enhances flow and reduces risk of damage.

Conclusion

  • Effective management of flow, space, and activity relationships is essential for efficient production and service delivery in facilities. Planning should be systematic and adapt to evolving operational needs.

    • Facilitate teamwork and collaboration to enhance productivity across different areas of an organization.
