Shop Floor Layouts Flashcards
Describe the attributes of a Process Layout.
- Functional grouping of activities
- Customisation of products possible
- Low fixed costs, high variable costs
- Skilled and versatile labour force
- General purpose equipment
- Low/fluctuating demand - Varied path
Describe the attributes of a Product Layout.
- Standardised goods
- Sequential arrangement of operations
- High/ stable demand
- Labour force cheaper/ less skilled
- Special purpose equipment - Fixed path
Quantify the production quantities.
1< quantity <100 (low production)
100< quantity <10000 (medium production)
<10000 quantity (high production)
What are the attributes of hard product variety?
Products manufactured differ substantially:
- low/no production of common parts
- Different product catagories
What are the attributes of soft product variety?
Only a small difference in products produced:
- High proportion of common parts - Different products within the same catagory
Draw the layout of a general production system.
Draw a annotated graph of product variety vs prodcution quantity.
What are the important considerations when selecting a production system?
Flexibility: The probable length of the production run
Variety: The number of product variants
Volume: the number of products to be produced
Size: the overall size of the product

What are the characteristics of a jobshop?
- Fixed position or process based layout
- 1 < prod. quantity < 100
- Low quantities
- Specialised and customised products
- Products are typically complex in nature
- Wide part and product variations
- Designed for maximum flexibility
- May include fabrication of the components
- Customer orders are generally special
- General purpose equipment is used
- Labour is high-skilled.
Flexible enough to deal with hard product variety.
What are the attributes of a fixed position layout?
Definition: Labour, equipment and materials are bougth to the location where the product is produced.
- Equipment, workers, materials and other resources brought to the site.
- Utilises highly skilled labour
- One location for entire the manufacturing period
What are the advantages and disavantages of a Fixed Position Layout?
Advantages of Fixed Position Layout:
- Reduces movement of work items.
- Minimises damage or cost of moving.
- More continuity of the assigned work force.
- Reduces the problems of re-planning and instructing people each time a new type of activity is to begin.
Disadvantages of Fixed Position Layout:
- Since the same workers are involved in more operations, skilled and versatile workers are required. The necessary combination of skills may be difficult to find and high pay levels may be necessary.
- Movement of people and equipment to and from the work site may be expensive.
- Equipment utilisation may be low because the equipment may be left at a location where it will be needed again in a few days rather than moved to another location where it would be productive.
