Facility Layout Chapter 6A
Learning Objectives • Understand how production processes are typically organized and the trade-off between efficiency and flexibility offered by each design. • Gain experience with the basic tools used to design workcenters, assembly lines, and manufacturing cells. • Recognize typical retail and office layout designs.
Layout Decisions • Facility layout: the process of determining placement of departments, workgroups within departments, workstations, machines, and stock-holding points within a facility • This process requires the following inputs: • Specification of the objectives used to evaluate the design • Estimates of product or service demand • Processing requirements • Space requirements for the elements • Space availability within the facility LO 1
Product–Process Matrix: Framework Describing Layout Strategies LO 4
Project Layout LO 3
Project Layout Continued • The product remains in a fixed location • A high degree of task ordering is common • A project layout may be developed by arranging materials according, to their assembly priority LO 3
Workcenter LO 3
WorkcenterContinued • Most common approach to developing this type of layout is to arrange workcenters in a way that optimizes the movement of material • Optimal placement often means placing workcenters with large interdepartmental traffic adjacent to each other • Sometimes is referred to as a department and is focused on a particular type of operation LO 3
Manufacturing Cell LO 3
Manufacturing Cell Continued • Group parts into families that follow a common sequence of steps • Identify dominant flow patterns for each part family • Machines and the associated processes are physically regrouped into cells LO 3
Assembly Line Balancing • Specify the sequential relationships among tasks • Determine the required workstation cycle time • Determine the theoretical minimum number of workstations • Select a primary and secondary assignment rule • Assign tasks • Evaluate the efficiency of the balance • Rebalance if needed LO 2
Example: Assembly Steps and Times for Wagon builtProduction of 500 Wagons and 8 hr/work shift (2-15 min. breaks and 30 mins. For lunch included) LO 2
Example: C and Nt Primary rule: Largest following tasks Secondary rule: Longest task time LO 2
Example: Assignment LO 2
Example: Efficiency LO 2
Service Businesses A service business is the management of organizations whose primary business requires interaction with the customer to produce the service • Generally classified according to who the customer is: • Financial services • Health care • A contrast to manufacturing
Retail Service Layout • Goal--maximize net profit per square foot of floor space • Servicescapes • Ambient conditions • Background characteristics, such as noise • Spatial layout and functionality • Planning the circulation path of customers and grouping merchandise • Signs, symbols, and artifacts • Parts of the service that have social significance LO 3
Office Layout • More open offices • Low divider walls • Size and orientation of desks indicates importance of people behind them LO 3
