The Next-Gen Supply Chain

6 The Next-Gen Supply Chain Is…  The Next-Gen Supply Chain Is Made Up Of New Technologies That Provide A Greater Degree Of: –AUTOMATION –VISIBILITY –CONTROL  The Next-Gen Supply Chain Is Designed To Remove: –TIME, –COST, –COMPLEXITY …. Out Of The Equation

7 Our Hypothesis  Supply Chain Planning ( SCP ) +  Supply Chain Event Management ( SCEM ) +  Supply Chain Integration ( SCI ) +  Supply Chain Execution Systems ( SCES ) + –Warehouse Management Systems ( WMS ) + –Manufacturing Resource Planning Systems ( MRP ) + –Transportation Management Systems ( TMS ) +  Global Trade Identification Number ( GTIN ) +  Global Location Number ( GLN ) +  Global Data Synchronization Network ( GDSN )  Product Information Management (PIM) +  Customer Relationship Management ( CRM ) +  Order Management Systems ( OMS ) +  Enterprise Resource Planning Systems ( ERP ) +  Web Services Definition Language ( WSDL ) +  Business Process Execution Language ( BPEL ) +  E-Business Xtensible Mark-up Language ( ebXML ) +  Automatic Identification and Capture ( AIDC ) +  Radio Frequency Identification Systems ( RFID ) +  Object Naming Service ( ONS ) +  Electronic Product Code ( EPC ) +  …  To Realize Real ROI, The Next-Gen Supply Chain Should Focus On Using These Technologies To Drive Visibility And Control Of: –Goods –Funds –Information  The Issue Is That Many Existing And Valuable Technologies And Standards Are Converging….

8 Next-Gen Supply Chain And The Technology Evolution  The Opportunity: –90% Of Real Gains In Deploying RFID/EPC Solutions Will Happen In The COLLABORATION Zone.  The Challenge: –Using XML And Web Services Technologies To Work Together In A Standards-Based Manner To Improve The Velocity And Flow Of Funds, Goods And Information Throughout Complex Global Supply Chains While Reducing Production, Distribution and Inventory Costs.

What Makes XML Ideally Suited for EPC/RFID Data?

10 XML’s Relevant Benefits For EPC/RFID  EPC/RFID Data and Supply-Chain Applications In The Domain: –Most of the EPC/RFID Standards Are XML-Based –Data Should Be Represented In An Hierarchical Structure –Involves Multiple Data Types – EPC, Sensor, Location, PO, ASN, ePedigree, etc. –Requires Querying and Transformation Of Data  XML And Related Technologies Such As XQuery, XSLT…: –XML Can Embed Multiple Data Types –XML Can Embed Existing Data –XML Can Represent Data In A Hierarchical Structure –XML Can Re-Use Technology And Enable Inter-System Integrations –XQuery Can Provide A Single Point Of Access To All Enterprise Systems –XQuery / XSLT Can Be Used To Transform Into and From Multiple Formats –XQuery Allows the Comparison And Aggregation Of Data –XML And Related Technologies Have Rapid Adoption By The Industry

15 APPLICATION LEVEL EVENT – CONT. ECTime, denotes a span of time measured in physical time units: duration : long unit : ECTimeUnit  milliseconds ECReportSpec, specifies one report to be returned from executing an event cycle. An ECSpec contains a list of one or more ECReportSpec instances: reportName : string reportSet: ECReportSetSpec filter : ECFilterSpec group : ECGroupSpec output : ECReportOutputSpec reportIfEmpty : Boolean reportOnlyOnChange : Boolean ECReportSetSpec : CURRENT|ADDITIONS|DELETIONS ECFilterSpec, specifies what EPCs are to be included in the final report. IncludePatterns : List//list of epc patterns excludePatterns : List //list of epc patterns to exclude

17 Capture - Core Event Types  EPCISEvent - is intended to serve as a generic base class for all event types in this module as well as others.  ObjectEvent - represents an event that happened to one or more entities denoted by EPCs. Includes list of EPCs in this object.  AssociationEvent - represents an event that implies an association between one or more entities denoted by EPCs. Example: aggregation (different EPCs)  QuantityEvent - represents an event concerned with a specific quantity of entities sharing a common EPC class, but where the individual identities of the entities are not known. (Individual not reported)

18 EPCIS Query Interface define(queryname:String, query:Query)Register query with EAGEPCIS undefined(queryName:String)Remove the query by name subscribe(queryName:String, dest:URI, SubscriptionControls controls)Register a subscriber for previously defined query unsubscribe(queryName:String, dest:URI)Removes previously registered subscriptions poll(queryName:String) : QueryResultInvokes a previously defined query immediate(query:Query) : QueryResultInvokes a query as specified by the query parameter returning results listQuerynames(): ListReturns a list of all query names listSubscriptions(queryName:String) : ListReturns a list of all URIs currently subscribed to the specified named query getQuery(queryName:String) : QueryReturns the query associated with a specified name
