Study Notes
Production Planning & Manufacturing Processes
- Manufacturing in large quantities presents challenges due to the variety and volume of materials, components, and "off-the-shelf" items needed. Quality control is crucial to ensure the product meets consumer expectations.
- Complex projects like ships, buildings, and bridges require meticulously planned manufacturing stages in the correct order. Expensive materials and specialized labor need to be onsite when required.
- Production planning systems help companies plan the order of processes and implement quality control. These systems track and manage the volume of materials and components, reducing costly mistakes.
- Flow charts are used to visually outline the stages of production and quality control, showing the sequence and the consequences of decisions. Based on quality checks, components can be sent back, recycled, or discarded.
- Gantt charts are used to schedule large projects with multiple, separate stages. These charts allow for the completion of stages simultaneously or sequentially, increasing efficiency and decreasing lead times.
Just-in-Time (JIT) Production
- JIT, pioneered by Toyota, prioritizes maximizing profits and minimizing capital investment.
- JIT is an "orders-led" approach where customer orders trigger production.
- Minimizing inventory and raw material storage saves money and reduces warehousing costs. The system relies on strong relationships with suppliers to provide materials quickly and in the correct quantities.
- JIT has a major goal of "zero inventory", where material and components are kept at a minimum, thus keeping costs down and the need for warehousing space minimized.
Kanban
- Kanban, generally a visual system, signals work stoppage at one manufacturing stage and a shift to the next as needed (e.g., low/high stock levels).
- Experienced and versatile workers are essential for Kanban systems. They must manage different manufacturing steps.
- Efficient processes and quick changes are essential. This means that equipment and machinery are designed for quick adjustment for different stages.
Advantages of JIT
- Reduced capital outlay for stock and raw materials
- Elimination of storage costs
- Fast turnaround on profits thanks to effective processes
- Improved efficiency through multi-skilled workers
- Prevention of material obsolescence or spoilage
- Reduced reworking time through quality control
Disadvantages of JIT
- Heavy reliance on supplier relationships for timely material delivery
- Lack of spare materials to accommodate unexpected demand fluctuations
- Traffic jams or other transportation issues can affect deliveries
- Cost of transportation, increased due to continuous deliveries.
- Limited room for errors since there's little extra material
Plastics Manufacturing Processes
- Plastics manufacturing uses mass production methods to create high volumes of output. The high cost of machinery and tools is compensated for by the increase in manufacturing volume.
Metal Manufacturing Processes
- Metal manufacturing processes can be classified as mechanical or thermal. The selection depends on the type of material being used and the desired product features. Different products demand differing standards.
- Various processes exist, each with specific advantages and disadvantages regarding cost, time, flexibility, and quality.
Wood Manufacturing Processes
- Wood-based products typically require skilled craftspeople for their production.
- Steps involved in assembly and finishes are also part of the wood manufacturing process and are essential when determining factors for efficiency.
