One of the standard control methods for such processes uses the so-called Kanban scheme, where the currently produced type is only switched when one of the buffers is about to run empty. Recently, an alternative method started to receive increasing attention: the so-called Heijunka scheme that realizes strictly periodic schedules. We compare both methods and apply them to a simplified manufacturing process that mimics a real-world process at an electronic circuit board manufacturer. The experiments show that Kanban is very well suited for the startup phase of the process, because no knowledge about the expected process statistics is required, the buffer levels are lower, and the maximum ability to deliver is reached much faster than with the Heijunka method. After the startup phase, however, the experiments indicate that Heijunka is preferable, because then it yields lower buffer levels and higher average ability to deliver than Kanban. Thus, the optimal control strategy for the type of manufacturing processes under investigation initially uses Kanban and then switches over to Heijunka.","PeriodicalId":378407,"journal":{"name":"2011 9th IEEE International Conference on Industrial Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127879933","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}

On the other, semantic web technologies that directly address this data enrichment and knowledge extraction. Further, smart grids will be formed of a galaxy of intelligent nodes controlling one or more network components; therefore, we propose a tree architecture inspired by the actual hierarchy of the power network and claim that, in this domain, regarding the tangled bunch of standard protocols, one global ontology based on the CIM (Common Information Model) suffices, since it may be extended, combined with other existing protocols, and divided into smaller, interoperable profiles stored in each node of the grid. To this end, we present a comparison among several local semantic knowledge repository solutions and cope with the query federation problem: how to retrieve and manipulate this distributed information. Finally, we illustrate this novel scenario with a real-world implementation.","PeriodicalId":378407,"journal":{"name":"2011 9th IEEE International Conference on Industrial Informatics","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116096997","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}

Influence factors are not restricted to process planning and the results of planning processes, but also consider the whole product life cycle and its impact on the manufacturing of products.
