Intermittent Production
Definition
Intermittent production is a manufacturing methodology in which several different products are produced on the same production line, though not simultaneously. Production line work for one product stops before work on a second product begins. This method maximizes productivity by utilizing the same equipment and facilities to produce different items.
Examples
Automobile Manufacturing: A factory may produce different models of cars on the same assembly line. For example, the line produces SUVs in the morning and sedans in the afternoon.
Consumer Electronics: A production line might be used to assemble several different types of electronic devices, such as smartphones and tablets, by altering the tools and processes involved.
Appliances: A single production facility might switch production between refrigerators, washing machines, and microwaves, depending on demand.
Frequently Asked Questions
Q1: What are the advantages of intermittent production?
- A: Flexibility in managing different products, efficient use of resources, and the ability to quickly switch production based on market demand.
Q2: What are the disadvantages of intermittent production?
- A: Increased complexity in planning and scheduling, potential downtime during changeovers, and higher levels of inventory management.
Q3: How does intermittent production differ from continuous production?
- A: Continuous production is a non-stop manufacturing process for a single product, while intermittent production involves producing different products sequentially on the same line.
Q4: What industries commonly use intermittent production?
- A: Automotive, electronics, apparel, and household appliances industries frequently adopt intermittent production due to diverse product ranges and fluctuating demands.
Q5: Are there specific tools required for intermittent production?
- A: Yes, fixtures, jigs, and setups may need to be modified or replaced when switching products to ensure quality and efficiency.
Related Terms
Batch Production: Production method where products are manufactured in groups or batches rather than one at a time.
Job Shop Production: A production process where small quantities of custom products are made to order, each having different requirements.
Continuous Production: Non-stop production process focusing on manufacturing large quantities of a single product.
