Manufacturing time refers to the total time taken to produce a specified quantity of products. This encompasses all stages from the start of production to the end, including set-up time, processing time, wait time, and any delays.
Historical Context
Manufacturing time has evolved significantly through the industrial revolutions:
- First Industrial Revolution (late 18th to early 19th century): Introduction of mechanical production facilities, leading to a focus on reducing manufacturing time through mechanization.
- Second Industrial Revolution (late 19th to early 20th century): Introduction of assembly lines and mass production techniques which significantly reduced manufacturing time.
- Third Industrial Revolution (late 20th century): Integration of digital technology and automation, further reducing manufacturing time through sophisticated machines and control systems.
- Fourth Industrial Revolution (21st century): Leveraging IoT, AI, and advanced robotics to optimize and predict manufacturing time with unprecedented precision.
Types/Categories
- Cycle Time: The total time from the beginning to the end of a process, as defined by the customer.
- Setup Time: Time required to prepare and configure a machine or production line for operation.
- Lead Time: The total time from receiving an order to delivering the final product.
- Takt Time: The pace at which products need to be completed to meet customer demand.
Key Elements
Components of Manufacturing Time
- Processing Time: Time spent actively manufacturing the product.
- Queue Time: Time the product spends waiting in line before it is processed.
- Setup Time: Time required to set up or reset machines.
- Move Time: Time taken to move products between different stages of production.
- Wait Time: Idle time between different manufacturing phases.
Mathematical Models and Formulas
The following formulas are essential in calculating manufacturing time components:
- Cycle Time: \( \text{Cycle Time} = \frac{\text{Total Production Time}}{\text{Number of Units Produced}} \)
- Lead Time: \( \text{Lead Time} = \text{Pre-Processing Time} + \text{Processing Time} + \text{Post-Processing Time} \)
- Takt Time: \( \text{Takt Time} = \frac{\text{Available Production Time}}{\text{Customer Demand}} \)
