Introduction to Rhythm Factory PlannerMay 17,2000AgendaWhat Is Rhythm Factory Planner(FP)Rhythm FP ArchitectureRhythm Factory Planner(FP)Planning ConceptRhythm FP featuresWhat Is Rhythm Factory Planner(FP)?What Is Rhythm Factory Planner(FP)Factory Planner uses the information from the existing transaction system(ERP)to provide intelligent decision support capability in Planning and SchedulingFactory Planner provides a global integrated view PurchasingOrder EntryShippingMRPFactory PlannerFloor ControlDataDecisions&DataWhat Can Rhythm FP Do?Factory Planner provides a systematic and constraint-based planning conceptFactory Planner can help to minimize the current ad-hoc planning processFactory Planner can quickly reveal the production constraint,which is almost impossible for traditional planning processRhythm FP ArchitectureRhythm FP ArchitectureClient-Server ArchitectureBoth server and client processes can run on Windows NT machinesMay run server and client on separate

ConceptBTO(Build-to-order)engine:use Demands as the driver to create planConsider both material and capacity constraints at the same timeConsider both Sales Orders and Forecasts as the demand input with different prioritiesStart as an Infinite Capacity Plan and progress to a Finite Capacity PlanFP Planning Concept(cont.)Materials are assigned according to the BOM explosion from the finish good levelalso consider Time factorsRaw Materials(Procured Parts)are supplied by on-hand inventory or P.O.from vendors.Manufactured parts(finish goods and intermediate parts)are supplied by WIP or manufacturing orders(work orders).Process Flow in FPInfinite Capacity PlanningFinite Capacity PlanningCAO(constraint anchor optimization)Detail SchedulingIdentify Material and Capacity ProblemsFix Material ProblemsAttempt to fix Capacity ProblemsCreate detailed schedulesFP Infinite Capacity Planning(ICP)Build factory model phaseInventory Assignment phasePlanned start time phaseCapacity utilization phasePresents plan through user interface(client)ICP-Build Factory ModelRead files into memory and create resident memory modelFile formats in Spec FilesDo consistency checkingICP-Inventory AssignmentExplore Bill of MaterialsDetermines BOM configuration and routing assignmentsCreates manufacturing orders to satisfy demandsNet requirements for raw materials and sub-assemblies against on-hand inventory and WIP(Work-In-Process)Creates material requirementsICP-Inventory Assignment(cont.)Backward Schedule Definition:Latest Possible Start Time(LPST)-the latest date a manufacturing task can begin and still complete on timeLPST=Task Due Date-Task Processing timeCalculates the LPST for each manufacturing taskEach manufacturing task will have a LPSTSoft

task can begin(constrained by materials)EPST=max(Server Start Time,Material Available Time)Calculates the EPST for each manufacturing taskEach manufacturing task will have an EPSTHard

material availability into considerationCalculation:PST=max(EPST,LPST)Each manufacturing task will have a PSTPST values may be overriden through the user interfaceICP-Capacity UtilizationDetermine bucket(operation time interval)configuration-from variable capacity bucket size dataCalculate capacity for each bucket-from resource calendar dataCalculate work load in each bucket based on PST and run time of each taskFP Finite Capacity PlanningIdentify the constrained resourcesBalance and offload loads for constrained resources in a GLOBAL view(Global optimization)Plan based on flexible strategy options(e.g.Minimize WIP)Respond quicklyFP Detail SchedulingSchedule based on flexible strategy options(e.g.FIFO)Able to specify the scheduling horizonAble to generate a global optimized
