Facilities Design Flashcards
Types of production systems
- Mass
- Batch
- Small Lot
Mass Production
High volume output, standardised products, use of assembly lines, automated processes
(Car manufacturers, Electronics, etc)
advantages and disadvantages of mass production
Advantages:
- lower costs per unit
- faster production times
- consistent product quality
- ability to meet high demand.
Disadvantages:
- less customization
- high initial setup costs
- job monotony for workers
Batch Production
process where items are produced in groups or batches rather than in a continuous stream
flexibility in production, enabling changes between batches
(Bakeries, Fashion, etc)
advantages and disadvantages of batch production
Advantages:
- flexibility to produce different products
- ability to handle changes in demand
Disadvantages:
- downtime between batches for setup changes
- potential for inconsistent quality
- higher costs
Small Lot Production
manufacturing approach where small quantities of products are produced at a time, reducing inventory and enhancing flexibility
(Custom Furniture, High-End Electronics for Aerospace, etc)
advantages and disadvantages of small lot production
Advantages:
- reduced inventory costs
- increased production flexibility
- quicker response to market changes
- improved product quality.
Disadvantages:
- longer setup and changeover times due to frequent production adjustments
- increased costs
What is a cell-based system in small lot production?
A layout strategy where workstations or equipment is grouped into cells to efficiently produce specific parts or products in small lots.
How does a cell-based system improve flexibility in small lot production?
Cells can easily adapt to different product variations or small production runs, allowing for quick changeovers.
Computer Integrated Manufacturing (CIM)
a manufacturing approach that uses computers to control all aspects of the production process, complete automation
benefits of CIM
- improved product quality
- reduced costs
- efficiency in all aspects
factors that influence facility layout
- volume of items to be produced
- nature of the service
- product mix
- lifetime of the product or component
characteristics of a good layout:
- reduces delays in moving people or material
- minimises materials-handling costs
- reduces hazards to personnel
- utilises people and available space efficiently
- provides flexibility
- provides ease of supervision
