Dan Reid & Nada R. Sanders4th Edition © Wiley 2010© Wiley 2010 2Learning ObjectivesDefine layout planning and explain its importanceIdentify and describe different types of layoutsCompare process layouts & product layoutsDescribe the steps involved in designing a process layout© Wiley 2010 3Learning Objectives – con’tDescribe the steps involved in designing a product layoutExplain the advantages of hybrid layoutsDefine the meaning of group technology (cell) layouts© Wiley 2010 4What Is Layout Planning?Layout planning is deciding the best physical arrangement of all resources within a facilityFacility resource arrangement can significantly affect productivityTwo broad categories of operations:Intermittent processing systems – low volume of many different productsContinuous processing systems – high volume of a few standardized products© Wiley 2010 5Types of LayoutsFour basic layout types consisting of:Process layouts - Group similar resources togetherProduct layouts - Designed to produce a specific product efficiently Hybrid layouts - Combine aspects of both process and product layoutsFixed-Position layouts - Product is two large to move; e.g. a building© Wiley 2010 6Process LayoutsProcess layout unique characteristics include:Resources used are general purpose Facilities are less capital intensiveFacilities are more labor intensiveResources have greater flexibilityProcessing rates are slowerMaterial handling costs are higher© Wiley 2010 7Process Layouts – con’tScheduling resources & work flow is more complexSpace requirements are higher© Wiley 2010 8Product LayoutsProduct layout unique characteristics are:Resources are specializedFacilities are capital intensiveProcessing rates are faster Material handling costs are lower Space requirements for inventory storage are lowerFlexibility is low relative to the market© Wiley 2010 9Process vs. Product Layouts Here are the characteristic differences between a process and product layout.© Wiley 2010 10Hybrid LayoutsCombine elements of both product & process layoutsMaintain some of the efficiencies of product layoutsMaintain some of the flexibility of process layoutsExamples: Group technology & manufacturing cellsGrocery stores© Wiley 2010 11Fixed-Position LayoutUsed when product is largeProduct is difficult or impossible to move, i.e. very large or fixedAll resources must be brought to the siteScheduling of crews and resources is a challenge© Wiley 2010 12Designing Process LayoutsStep 1: Gather information:Space needed, space available, identify closeness measuresStep 2: Develop alternative block plans:Using trial-and-error or decision support toolsStep 3: Develop a detailed layout:Consider exact sizes/shapes of departments and work centers including aisles and stairwaysTools like drawings, 3-D models, and CAD software are available to facilitate this process© Wiley 2010 13Special Cases of Process LayoutsA number of unique process layouts require special attention. We will look at two of these:Warehouse layoutsOffice Layouts© Wiley 2010 14Warehouse LayoutsWarehouse Layout Considerations:Primary decision is where to locate each department relative to the dockDepartments can be organized to minimize “ld” totalsDepartments of unequal size require modification of the typical ld calculations to include a calculation of the “ratio of trips to area needed”The usage of “Crossdocking” modifies the traditional warehouse layouts; more docks, less storage space, and less order picking© Wiley 2010 15Office LayoutsOffice Layout Considerations:Almost half of US workforce works in an office environmentHuman interaction and communication are the primary factors in designing office layoutsLayouts need to account for physical environment and psychological needs of the organizationOne key layout trade-off is between proximity and privacyOpen concept offices promote understanding & trustFlexible layouts incorporating “office landscaping” help to solve the privacy issue in open office environments© Wiley 2010 16Designing Product LayoutsDesigning product layouts requires consideration of: Sequence of tasks to be performed by each workstationLogical orderSpeed considerations – line balancing© Wiley 2010 17Designing Product Layouts – con’tStep 1: Identify tasks & immediate predecessorsStep 2: Determine output rateStep 3: Determine cycle timeStep 4: Compute the Theoretical Minimum number of StationsStep 5: Assign tasks to workstations (balance the line)Step 6: Compute efficiency, idle time & balance delay© Wiley 2010 18Step 1: Identify Tasks & Immediate Predecessors© Wiley 2010 19Layout CalculationsStep 2: Determine output rateVicki needs to produce 60 pizzas per hour Step 3: Determine cycle timeThe amount of time each workstation is allowed to complete its tasksLimited by the bottleneck task (the longest task in a process):  sec./unit 60units/hr 60sec/min 60x min/hr 60units/hroutput desired sec./day time available)(sec./unit time Cycle hourper pizzasor units/hr, 72sec./unit 50sec./hr. 3600time task bottlenecktime availableoutput Maximum © Wiley 2010 20Layout Calculations con’tStep 4: Compute the theoretical minimum number of stationsTM = number of stations needed to achieve 100% efficiency (every
