54 SMT007 MAGAZINE I SEPTEMBER 2018 lean material engine can determine the ideal location from which to move components and automatically initiate the movement transac- tions. The consumption data reported by the individual machines can be aggregated and extremely accurate reports made to the ERP system. Finally, the large line-side buffer stocks are unnecessary. Material is ordered from the warehouse or from Kanban storage only when it is needed on the machine. With the automat- ed reporting of consumption and wasted mate- rials from the machine, the ERP inventory is as accurate as possible Traceability Application The collection of traceability data has tradi- tionally been a difficult requirement for man- ufacturers. The complexity and cost associat- ed with collecting detailed, accurate data could lead to inconsistent results as individual trace- ability requirements are negotiated between the customer and supplier on a product-by- product basis. To improve the effectiveness and consis- tency of traceability data collection, the IPC- 1782 standard was developed to define a clear, industry-wide specification for traceability. The standard features several levels of trace- ability based on the risk involved in the prod- uct or process. The individual traceability lev- els vary in the detail and accuracy of the data being collected. At the lowest level, summa- rized data is collected manually by operators, and at the highest level, comprehensive data must be collected primarily from automated equipment. When taken as part of the smart factory, the requirements for traceability data collection can be fulfilled by the existing process applica- tions in the smart factory infrastructure. Pre- viously, this paper explored solutions utiliz- ing much of the data that would be relevant for traceability purposes: equipment status and progress, detailed material information, test and inspection results, etc. Since the pro- cess applications support a neutralized lan- guage and a normalized set of events, consis- tent information can be aggregated by the site la yer applications regardless of the machine platform. This supports the need for detailed and consistent data regardless of the equip- ment platform. Using the IPC-1782 standard format, the summarized traceability information aggregat- ed by the site application layer can be trans- ferred to the enterprise applications and exter- nally to the relevant customer. Connecting the three layers of smart solutions through ven- dor-neutralized, standard formats, reduces the complexity required to implement a meaning- ful traceability solution. Conclusion Many opportunities exist today to implement improvements based on automation of man- ufacturing processes and business processes using the smart factory infrastructure. In this way, machine vendor solutions are enhanced through the exchange of information with oth- er machines and site applications. By collecting data from all manufacturing processes, histori- cally troublesome requirements, such as trace- ability, become easier to fulfil. This leads the industry to a greater adoption of smart manu- facturing functionality. SMT007 Editor's Note: Originally published in the proceedings of SMTA International, 2017.
