Discrete event simulation has been used in the evaluation of computer communications networks for three or four decades. Over this period of time our simulation capability has improved significantly due to the efforts of the simulation research community. There has also been significant progress over the years by the networking research community in understanding the use of simulation in the design and evaluation of network architectures, protocols and services. I will argue in this talk that, despite these advances, we still do not have an acceptable and widely-used methodology to simulate networks which often leads to the questioning of the credibility of simulation results. This can be attributed to many reasons, including 1) confusion and uncertainty within the networking community regarding the role that simulation plays in networking research, 2) fundamental limits that make it basically impossible to simulate Internet-scale networks, 3) the difficulty in building realistic network models and 4) the lack of acceptable standards for validity and repeatability of simulation experiments. I will suggest a high-level research agenda that addresses these issues with the ultimate aim of enriching the networking research community's ability to use simulation as a meaningful tool for performance evaluation and prediction.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"128 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120985080","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}

Ag is a simulation language based on the typed X-calculus. Xa entities correspond to typed X-expressions, while Xa activities correspond to subtypes. Thus, entities can be generated by means of type-introduction rules, and operations can be defined on entities by means of type elimination and equality rules. Premises of the form e E r in an introduction rule used to create a new entity can be satisfied by substituting for e any entity of type r in a neighboring activity. It is then possible to perform a number of model analysis and verification operations using type inference algorithms available for the typed X-calculus.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115217388","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}

However, at least one optimistic mechanismis able to beat the critical path bound in a nontrivial way. bounded by its length and when it is not. We show (again) that no conservative mechanism can beat the critical path bound, but we also show that at least four known optimistic mechanisms, Time Warp with lazy cancellation, Time Warp with lazy rollback, Time Warp with phase decomposition, and the Chandy-Sherman space-time family of mechanisms, all can do so.

A performance measure which represents an 'actual' production rate of a machine is defined in order to identify bottlenecks.

This new approach is applied for redesigning an actual large-scale multi-stage flow-shop production line in the authors' steelworks and they can determine the proper specifications of this line which can achieve an increase of productivity with a minimal investment.

The objective of this work is to estimate the finite buffer size of the queues such that packets (elements) arriving to the system at a lower rate than one fixed have a very low probability — usually, less than 10-8 — to be rejected (because the buffer is full). To carry out this task only by means of simulation would require a large amount of computational effort. Extreme value theory is employed to estimate, from the results of a reduced simulation, which buffer size corresponds to this loss probability.\u0000The extreme value theory is presented and the way it can be applied to the simulation analysis is explained. Further refinements, in order to extend its extrapolative capability, are introduced, and also the way to calculate confidence intervals. Numerical results are presented.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126138367","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}
