Study Notes

Manufacturing Systems Aspects

  • Manufacturing systems are defined by physical systems, operations, information systems, and people.

Physical Systems

  • Facilities: Buildings, warehouses, and structures housing the manufacturing process.
  • Equipment: Machinery, tools, and assets used to transform raw materials into finished products.
  • Material Handling Systems: Equipment and processes moving materials within the facility (e.g., conveyor belts, robots, forklifts).

Operations

  • Production Planning and Scheduling: Determining what products to make, in what quantities, and when. Includes scheduling equipment and labor.
  • Process Design: Planning the sequence of steps to transform raw materials into finished products.
  • Inventory Management: Efficient ordering, storage, and use of materials.
  • Quality Control: Ensuring products meet required standards.
  • Maintenance: Keeping equipment and machinery in good working order.

Information Systems

  • Manufacturing Execution Systems (MES): Systems collecting and tracking data from the manufacturing process (e.g., production rates, machine downtime, inventory levels).
  • Enterprise Resource Planning (ERP) systems: Systems integrating information from all business aspects (manufacturing, finance, sales).
  • Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM): Technologies used to design products and create instructions for manufacturing.

People

  • Workers: Personnel operating equipment and performing tasks to produce goods.
  • Managers: Individuals overseeing the manufacturing process and making decisions for improvement.
  • Engineers: Professionals designing and developing new products and manufacturing processes.

Manufacturing Systems Structure

  • The structure includes hierarchical levels from enterprise to station, relating to strategic resources, strategies, and operational rules.

Manufacturing Systems Transformation

  • Key advancements in manufacturing, such as Toyota Production Systems (TPS), Flexible Manufacturing Systems (FMS), and Reconfigurable Manufacturing Systems (RMS) are discussed.
  • There is an increase in system flexibility, responsiveness, and efficiency over time.
  • Cloud-based manufacturing systems (CBMS) are also mentioned.

Integrated Manufacturing Systems

  • Computer-Integrated Manufacturing (CIM) is defined as a manufacturing approach utilizing computer-controlled machinery and automation.
  • The four major functions in an integrated system are production, design, management, and strategic planning.

Integrated Manufacturing Systems Calculations

  • An example of calculating utilization rate for producing car suspension springs in a manufacturing system is provided.
  • Calculations of total available production time, actual production time, total springs produced, and the utilization rate of an integrated manufacturing system are shown.
  • Another example features a system assembling three components (A, B, C).
  • Option 1 (sequential processing) and Option 2 (parallel processing) are analyzed in terms of daily production time.
