Recent trade reports suggest that RFID implementation continues to lag lofty projections. A primary concern is that, despite the high cost of implementing RFID systems, realized read‐rates fall short of expectations. This results in the invisible inventory conundrum whereby tagged merchandise may still not be accurately represented in inventory records. Drawing from data science to address this issue, we ask: How can directed data mining models be used to identify laboratory test performance criteria for RFID tags that operate reliably across the idiosyncratic facilities (i.e., unique DCs, warehouses, and stores) that comprise apparel retailers’ supply chains? We investigate this question by advancing a methodology that integrates laboratory test performance data, field tests of RFID tags fixed to apparel items and scanned under normal operating conditions, and the application of five directed data mining models to the integrated data set of laboratory and field test results. Our analyses of 45,416 observations show that two directed data mining models may identify—with near‐100% accuracy—laboratory test criteria that discriminate tags having 99% or greater read‐rates in the field. Accordingly, our study validates a generalizable methodology for identifying technical performance standards for tags that operate reliably within apparel retailers’ supply chains. 相似文献

Westinghouse Electric opened a new research laboratory nearthe companys main factory in East Pittsburgh, Pennsylvania,in 1916. Located in the suburban borough of Forest Hills, thelaboratory was set up to provide scientific knowledge for theolder materials testing and product development laboratoriesat the factory. Unlike its industrial counterparts, however,the Forest Hills laboratory was dominated by a strong engineeringresearch tradition that disrupted efforts undertaken in the1920s and again in the 1930s to build and sustain a diversifiedfundamental research program. Whereas Eastman Kodak, DuPont,AT&T, and General Electric had successfully integrated fundamentalresearch into their corporate laboratories, the Forest Hillslaboratory remained the site of recurring tensions between twocultures of innovationone based on fundamental science,the other on engineering research. Although such tensions oftenresulted in competing research strategies, managerial conflicts,and mismatched corporate priorities, the long-standing cultureof engineering research contributed far more to Westinghousesstrategic growth than even the most advanced fundamental research.More generally, the interactions between the cultures of engineeringand science that characterize the early history of industrialresearch at Westinghouse highlight the evolving and sometimesconflicting patterns of technological innovation and organizationalchange in American industry before World War II. 相似文献
