Introduction to Facilities Design Chronological list of facilities planning and design activities Date Event 4000 B.C. Egyptians developed expertise in finding suitable locations for pyramids according to their astrological calculations 100 B.C. B 100 Romans developed full-fledged methods for the construction of A.D. temples, arenas, and other buildings. Detailed planning of public and residential buildings 1700 B 1900 1910 Industrial revolution period First industrial engineering text book Factory Organization and Administration published by Hugo Diemer. 1913 First moving automotive assembly line introduced by Henry Ford. Chronological list of facilities planning and design activities 1954 Quadratic assignment problem for micro- andmcro-levl location problems introduced by Koopmans and Beckman 1955-1995 Optimal and heuristic algorithms for the quadratic assignment problem 1959 Systematic layout planning approach introduced by Muther 1963 CRAFT (Computerized relative allocation of facilities technique) introduced by Armour and Buffa Chronological list of facilities planning and design activities Early 1980s The flexible manufacturing system concept is introduced and attention shifts towards achieving plant-wide flexibility via medium-volume, medium-variety production using cellular manufacturing techniques Late 1980s The term automation introduced to cope with plant flexibility requirements 1985-present Modern software for facilities design problems 1990s-present Research on new layout concepts including dynamic layouts, robust layouts, and reconfigurable layouts introduced to support mass customization techniques Typical Design and Planning Problems Facility Location Type, Number of Material Handling Devices Determining Flow of Products (People) Type, Volume of Products to be Manufactured or Service to be Provided Determining Material Handling Methods Scheduling and planning of Jobs (Service steps) Manufacturing (Service) Processes Required Layout of Equipment Within Each Cell Design of Components (Service) Layout of Machine (Service) Cells Inventory Control Type, Number of Equipment Required Determination of Machine (Service) Cells Distribution of goods Process Planning Tooling, Fixture Determination Quality Control and Customer Service Overall System Design Levels of decisions • Strategic or Design or Long-term • Planning or Intermediate • Operational or short-term Why is facilities layout important? • 20-75% of product cost attributed to materials handling (Sule, 1991 and Tompkins et al. 2003) • Layout of facilities affects materials handling costs • Facilities includes machines, departments, workstations, locker rooms, service areas, etc. Why is facilities layout important? • Good layout increases productivity efficiency • Reducing congestion permits smooth flow of people and material • Space utilization is effective and efficient • Facilitates communication and supervision • Safe and pleasant working environment Constraints in developing facilities layout • Some pairs of departments must be adjacent • Some pairs of departments must not be adjacent • Some departments only in specific locations • Existing building constraints • OSHA regulations, fire codes, etc. Types of layout problems – Some examples • JIT manufacturer • Relayout of an existing facility • Relayout due to increased traffic (resulting from a merger) • Consolidation of manufacturing operations from two or more sites to one • Leasing of office space in a multi-story building • Find a better layout in existing space • Introduction of new product lines Types of layout problems • • • • Layout of a service system Layout of a manufacturing facility Warehouse layout Nontraditional layout Applications • Manufacturing • Healthcare • Service – – – – Restaurants Banks Airports Entertainment • Logistics and Distribution – Ports/Terminals – Distribution Centers Types of Projects • New Facility • General Re-layout (retrofit) – – – – – – – – Expansion due to new product(s) Expansion due to sales growth in existing products Re-organization of work areas (evolutionary design) Outsourcing of logistics capability Addition of automation technology Problem elimination Cost reduction Product discontinuation Service system layout – Dentist’s office Staff Lounge X-Ray Room Records Room Orthodontist’s Room Dentist’s Room Oral Hygienist’s Room Oral Hygienist’s Room Men’s Rest Room Reception Waiting Area Women’s Rest Room Service system layout – Grocery store Operations review for office layouts (Suskind, 1989) • • • • • • • • Is the company outgrowing its space? Is available space too expensive? Is building in the proper location? How will a new layout affect the organization and service? Are office operations too centralized or decentralized? Does the office structure support the strategic plan? Is the new layout in tune with the company’s image Does customer physically participate in service delivery? Office structures • • • • Closed structure Semiclosed structure Open structure Semiopen structure Closed structure Semiclosed structure Teller Teller Teller Open structure Semiopen structure Manufacturing layout • Minimize transportation cost of raw materials, sub-assemblies, work-in-process inventory, tools, parts, finished products, etc. • Facilitate traffic flow • Improve employee morale • Minimize or eliminate risk of injury and property damage • Ease of supervision and face-to-face communication Assembly facility layout Driveway layout Warehouse layout Nontraditional layout • • • • Keyboard layout IC board layout Computer disk storage layout Airport gate layout
