Incorporation of visual displays into simulation systems is consequently of extreme importance, particularly in those simulations involving man-in-the-loop interactive systems (flight training, driver training, etc.). Presentation of effective visual displays have been driven by state of the art technology, and, despite massive efforts, has been hampered by a failure to consider the visual parameters of an observer and the mental processes involved in the perception of visual scenes.This paper provides a discussion of the visual parameters of the individual as well as of simulation systems and summarizes the current visual system display efforts.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114586301","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}

Process cycle time variability does not adversely affect the performance of a Kanban- linked process structure. However, it does lengthen product cycle time and product throughput time, and lower system utilization on directly linked process structure. Modifying a directly linked process structure to include one accumulator with one unit of float between each individual process eliminates these adverse effects.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131635246","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}

Synchronous activity is evident in so-called self-organizing systems, particularly muscle and brain tissues. This paper gives an exact matrix description of the rope model and shows that study of the synchronous behavior of this model can be done by applying Markov chain analysis. In modeling neural networks, however, such features as refraction, inhibition, noise, and discrete neuron responses frequently are incorporated in simulation models. Simulations are presented that indicate certain neural network models can be more simply modeled in part using a matrix representation similar to that for the rope game. A lemma is proved and used to obtain a formula for neuron firing expected in steady state.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133165598","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}

Discriminant rules are obtained for binary observation vectors from training samples drawn from two-group populations. Performance is evaluated primarily in terms of the error rate observed in the training and test samples for populations characterized by small and unequal training sample sizes, log-likelihood reversals, various correlation structures, and missing values. Some models are superior for certain population structures, and an attempt is made to identify data set characteristics that favor a particular model. Applications of the models are discussed, including their use as components in expert systems, and an expert system for consulting on discriminant analysis problems is reviewed.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131381584","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}

This Paper discusses development of a Meta-simulator for simulating and analyzing such systems. This could form a part of a general multi-processor system CAD package. The statistical results derived using the simulator can be used to generate Reduced Instruction Set Computing (RISC) elements providing reduced hardware complexity and improved overall system performance. Two methods of implementation - namely using, Instruction Set Processing Specification, ISPS and High Level Language, C are reviewed and compared. Evaluation of candidate architectures requires use of high level and assembly languages for writing benchmark programs for the simulator. We therefore discuss the notion of Meta-Assembler and Meta-Compiler also.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1987-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116574912","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}
