Presentation Outline • Importance of layout planning • Types of layouts • Comparing process and product layouts • Designing process layouts • Designing cellular layouts • Office layouts
What Is Layout Planning? • Layout planning is determining the best physical arrangement of resources within a facility
Why is layout planning important? • Eliminates unnecessary costs for space and materials handling • Reduces work-in-process inventory • Produces goods and services faster • Reduces distances that workers must travel in the workplace • Improves communication and morale • Increases retail sales • Improves brand image
Types of Layouts • Process layouts: Group similar resources together • Product layouts: Designed to produce a specific product, or a small number of products efficiently • Hybrid layouts: Combine aspects of both process and product layouts • Examples: cellular layout, grocery store • Fixed-Position layouts: Product is too large to move • Examples: building construction, shipyard • Resources must be brought to where they are needed
Process Layouts • Used in project and batch manufacturing (intermittent processes) • Also used in department stores, offices, hospitals, and universities • Able to make or sell a variety of products • Use general purpose resources • Less automation than in product layouts
Process Layouts (2) • Material handling costs per unit are higher than in product layouts • Scheduling production is more complex than in product layouts
Product Layouts • Used in assembly lines and continuous manufacturing (repetitive processes) • A cafeteria line is a product layout • In manufacturing, product layouts are used to produce one product, or a small group of products, efficiently • Uses special purpose resources • More automation than in process layouts
Product Layouts (2) • Material handling costs per unit are lower than in process layouts • Scheduling production is simpler than in process layouts
Designing Process Layouts • Step 1: Gather information: • Space needed, space available, importance of proximity between various units • Step 2: Develop alternative block plans: • Using trial-and-error or decision support tools • 2 approaches • Relationship (REL) chart • From-to matrix • Can use both • Decision support systems are heuristic methods • Usually give a "good" solution • Solution may not be optimal (best solution)
Designing Process Layouts (2) • Step 3: Develop a detailed layout • Consider exact sizes and shapes of departments and work centers including aisles and stairways • Tools like drawings, 3-D models, and computer-assisted design (CAD) software are often used

Cellular Layouts • Used to make parts in Just-in-Time Manufacturing • Based on group technology • Group technology (GT): A method of organizing parts into families with similar manufacturing requirements • A manufacturing cell is created for each part family

Office Layouts • Almost half the U. S. work force works in an office • Human interaction and communication are the primary considerations in office layouts • People who need to interact frequently should be close to each other • One key layout tradeoff is between closeness and privacy
Office Layouts (2) • Open concept officespromote understanding and trust. • A few closed rooms are needed for private discussions, such as personnel matters. • Moveable walls provide flexibility to change the layout when needed.
Office Layout Example3D Systems • Hi-tech company – provides equipment and materials for rapid product design and manufacturing • Rock Hill headquarters handles product design, sales, training, and administration • Open office plan • Conference room • Areas for informal meetings • Product showroom for customers • Cyber café and fitness center for employees
