Simulation is an enabling tool for experimenting virtually on a validated computer environment. Often the underlying function for the results of a computer simulation experiment has too much curvature to be adequately modeled by a low order polynomial. In such cases finding an appropriate experimental design is not easy. This research uses prediction variance over the volume of the design region to evaluate computer simulation experiments assuming the modeler is interested in fitting a second order polynomial or a Gaussian process model to the response data. Both space-filling and optimal designs are considered.","PeriodicalId":162289,"journal":{"name":"2008 Winter Simulation Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124871210","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}

Business process reengineering (BPR) often gets involved in the process of demand analysis and play a crucial role in the achievement of project objectives. Business process based simulation (BPS) provides a precise and visual method to analyze and compare the concerned performances before and after BPR. The paper presents an industrial experience in using the BPS tool to demonstrate the effects of BPR on restraining stocking-up and overdue payments in the distribution management of a supply chain. Before significant investment involved, the related design result of BPR is validated both by the analytical method and simulation experiments. Based on the mutual supportive results, the BPS method approves its correctness and show its nicety, flexibility and the capacity of visualization.","PeriodicalId":162289,"journal":{"name":"2008 Winter Simulation Conference","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124953962","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}

Since the early 80s, the cocaine market in the US and the rest of the world has been mainly supplied by Colombian cartels. Consequently, these illegal organizations have been targeted by Colombian and American law enforcement agencies. Our work argues that such policy has had a counter-intuitive effect which has contributed to increases in coca farming and reductions in cocaine prices. This paper hypothesizes that such situation was the consequence of the way that drug cartels were dismantled - thus the Colombian paradox. The consequences of the war against cartels may be assessed with the support of a dynamic theoretical framework and SD. This research assesses alternative policy for dismantling drug cartels.","PeriodicalId":162289,"journal":{"name":"2008 Winter Simulation Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125414573","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}

Different orders are grouped into one job because orders of an individual customer very often fill only a portion of a front-opening unified pod (FOUP). A FOUP is assigned to each job and is used to move the job throughout the wafer fab after the job formation. We determine an appropriate number of FOUPs for a given order release rate that will yield acceptable values for on-time delivery performance, cycle time, and throughput via discrete event simulation.","PeriodicalId":162289,"journal":{"name":"2008 Winter Simulation Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130163618","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}
