Material Flow in Production

Study Notes

Material Flow

Material flow refers to the movement of materials, goods, and products through the production process, from raw materials to finished products. It involves the planning, coordination, and control of the flow of materials to ensure efficient and effective production.

Types of Material Flow:

Linear flow: Materials move in a straight line from one operation to the next.
Job shop flow: Materials move in a irregular pattern, with different operations performed at different workstations.
Batch flow: Materials are processed in batches, with each batch moving through a series of operations.
Continuous flow: Materials are processed continuously, with no breaks or interruptions.

Objectives of Material Flow:

Minimize transportation costs: Reduce the distance and frequency of material movement.
Minimize inventory levels: Reduce the amount of inventory stored at each stage of production.
Maximize productivity: Increase the efficiency of production by reducing downtime and idle time.
Improve product quality: Ensure that materials are handled and stored properly to prevent damage and contamination.

Factors Affecting Material Flow:

Production volume: The quantity of materials being produced affects the material flow.
Production layout: The physical arrangement of equipment and workstations affects the material flow.
Equipment capacity: The capacity of equipment and machinery affects the material flow.
Labor availability: The availability of labor affects the material flow.
Material characteristics: The size, shape, and weight of materials affect the material flow.

Material Flow Systems:

Manual systems: Materials are moved and handled manually by workers.
Automated systems: Materials are moved and handled by automated equipment, such as conveyor belts and robots.
Semi-automated systems: Materials are moved and handled by a combination of manual and automated systems.

Material Flow Analysis:

Flowcharting: A graphical representation of the material flow process.
Simulation modeling: A computer-based model of the material flow process to analyze and optimize performance.
Material flow diagrams: A visual representation of the material flow process, showing the movement of materials and the relationships between operations.
