2 Daimler Uses RFID to Track and Trace Vehicles Testing the Mojix-System in a Quality Assurance Area

3 Breakdown I. The RAN project II. Use Case I Finished vehicles - quality assurance and distribution III. Quality assurance optimization 3

4 I. The RAN project - Motivation Natural events Snow chaos, storms, ash cloud, Technical complexities Machine damage, wear, Market conditions Economic, currency and raw material crises, Communication challenges Incompatibility of systems, [RAN] 4

5 I. The RAN project - Motivation High stock levels Long throughput times Special campaigns Production downtimes Poor traceability Inventory shrinkage Added search labour High resulting costs? [RAN] 5

6 I. The RAN project - Aims Increase transparency in production and logistic networks: development of an information broker concept with effective control methods Implementation of RFID technology: optimise physical processes through the automation of informational processes Findings: In order to work efficiently in a global network with different process partners (OEM, suppliers, logistics companies), industrial standards for optimizing the potential must be generated. [RAN] 6

7 I. The RAN project - Elements Processes Data and data structures Standardization Information broker and supporting systems RFID acquisition classes [RAN] 7

8 I. The RAN project - Partners [RAN] 8

9 I. The RAN project - Partners [RAN] 9

10 II. Use Case I Finished vehicles - quality assurance and distribution 10

11 II. Use Case I Finished vehicles - quality assurance and distribution 11

12 III. Quality assurance optimization - Layout Interior & Chassis OS1 IS1 Power Train OS2 IS2 Rain tests & Finish OS3 IS3 Buffer Buffer Buffer specialized area: Engine specialized area: Electric specialized area: Exterior OS IS Outfeed Station Infeed Station 12

13 III. Quality assurance optimization - Aims Reduce search time Reduce manual documentation Increase utilization of vehicle transporters Reduce administrative tasks 13

14 III. Quality assurance optimization - Aims Reduce throughput time Reduce delays Control vehicle status Control working station status 14

15 III. Quality assurance optimization - Technology [Mojix] 15

16 III. Quality assurance optimization - Proof of concept Master Controller Antenna enode 16

17 III. Quality assurance optimization - Proof of concept Antenna Mounting Using existing metal rails Fixing with brackets Centered above each car s windshield, facing down One antenna per parking spot 17

18 III. Quality assurance optimization - Test procedure 12 different tags were tested General-purpose Tags Flag Tags Rugged Tags 18

19 III. Quality assurance optimization - Test procedure 22 different positions on and in the vehicle were tested 19

20 III. Quality assurance optimization - Suitable positions are Rear-view mirror Central console Test results Rear-view mirror was chosen Best read-rate Enough space in the mirror Early assembly of the mirror and low error rate 20

21 III. Quality assurance optimization - Test documentation 21

22 III. Quality assurance optimization - Test results Tests of environmental influences: Working on the vehicle Opening and closing of doors/ bonnet/ trunk Moving of vehicles Using the car lift Tests of interferences: Other applications in the Mojix radio range (keys, testing equipment) Other RFID-applications (handheld, gate) Accuracy and reliability are satisfying 22

23 III. Quality assurance optimization - Outlook Implementation of the connection between Mojix and the production control system Tests of the implementation of Mojix in the S-Class Quality assurance area 23
