It requires the systematic examination of information to identify potential threats, emerging issues and opportunities to improve resilience and decrease risk exposure. Horizon scanning can use the Web to augment the acquisition of information, though this involves a search for novel and emerging issues without knowing them beforehand. To optimise such a search, we propose the use of relevance feedback, which involves human interaction in the retrieval process so as to improve results. As a proof-of-concept demonstration, we have carried out a horizon scanning exercise which showed that our implementation of relevance feedback was able to maintain the retrieval of relevant documents constant over the length of the experiment, without any reduction. This represents an improvement over previous studies where relevance feedback was not considered.","PeriodicalId":391609,"journal":{"name":"2013 Federated Conference on Computer Science and Information Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129056450","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}

It reduces the operating efficiency of the chain and blocks the operating resources. Some of the common causes of BWE are demand order variations, long lead times, competence defects between supply chain links, lack of communication among links in the chain, etc. There have been efforts to overcome these issues. However, very little work has been reported based on formal representation and analysis of resource flow in the supply chain system. In this work, a novel framework is proposed using Generalized Stochastic Petri-net (GSPN) model towards handling this issue in a distributed scenario. The analysis on the stochastic nets allows identifying the bottlenecks in the supply chain echelons along with customer relationship management (CRM). This has been used to rebuild infrastructure with the end-objective of reducing the BWE.","PeriodicalId":391609,"journal":{"name":"2013 Federated Conference on Computer Science and Information Systems","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134301208","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}
