Details that cannot be printed on paper such as the latest information or information about related services are published on the Internet. However there are various problems. Inputting a URL while looking at the printed material is troublesome, input mistakes can happen, and even if there are multiple information items introduced on the printed material usually only the URL to the top page of the website is noted, making it difficult to locate the desired information. Also, while cellular phones with attached cameras are rapidly spreading worldwide, QR code is gaining popularity in Japan as a technology to link existing media. However, the usage of many recognition technologies has been hampered by problems with the layout and design regarding existing media. This research examines mobile marketing methods using digital watermarking technology as a method to conquer these problems.","PeriodicalId":306564,"journal":{"name":"2009 2nd International Symposium on Logistics and Industrial Informatics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130208491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
{"title":"The Fragmented Warehouse: Location Assignment for Multi-Item Picking","authors":"S. Ho, S.

With the emergence of automatic identification and tracking technologies like RFID, free-form storage of goods becomes a viable alternative. We consider the strategy of storing identical copies of an SKU in a fragmented manner and evaluate the operational characteristics that benefit from fragmented storage. Fragmented storage of identical SKUs creates a greater number of feasible pick- list opportunities -- with greater choice, greater optimization follows. We present an abstract warehouse model to evaluate the location assignment problem in warehouse systems. Specifically, we investigate picking operations that retrieve multiple items during a warehouse pass. We provide an analytical result for operations using a 'hybrid-cost' cost metric, and a brute force analysis for operations using the more common 'maximum-cost' picking metric. We show that fragmentation is more favorable when the number of copies picked for each SKU is small.","PeriodicalId":306564,"journal":{"name":"2009 2nd International Symposium on Logistics and Industrial Informatics","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129720288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
