The basic conclusion is that use of a good, theoretically exact transformation in conjunction with a theoretically good unit uniform generator does not necessarily guarantee variates with good statistical properties. In many cases generators which aren't quite so good when combined with transformation algorithms which also aren't quite so good, will yield variates with statistical properties which are superior to those of the “better” generators.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114403863","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}

A typical ground station might contain ten computers with associated disks and memories and must process large quantities of data in real-time. The selection of the hardware, the design of the computer system architecture and software is a prodigious task and presents a high risk in terms of the performance and cost of the final system if adequate design data is not available early in the design process. The DPSSGS is a generic model of multi-tasking computers and computer networks and provides a design tool for analyzing the many alternate computer configurations proposed in the design of a ground station. Although the impetus for the development of the DPSSGS came from the designers of ground stations, application to a wider range of data processing systems is possible. The DPSSGS was applied extensively to the design of a recent ground station.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121919628","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}

The research examined the impact of maintenance concepts, as implemented by changes in the decision variables associated with the potential application of Automatic Test Equipment. The initial effort consisted of data collection and field site surveys which culminated in defining a work flow model illustrating typical repair facility operations. The work flow model was translated into a computer simulation model. The baseline model contained all the values for failure rates, delay times, and probability decision parameters derived from the available field data. The simulation model was then exercised and the output data recorded for comparison with historical data to validate the model and provide a baseline for comparison as the decision parameters were varied. Of those variables exercised it appears that the Built-in-Test (BIT), or Self-test capability, is one of the more important design considerations in the original operating systems. The programming language used for the simulation model is entitled FLOW SIMULATOR, a UNIVAC version of GPSS.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126254873","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}

Discrete system simulation offers several advantages over continuous simulation. Discrete simulations are homomorphic with the life cycle of the insect and are less computationally complex. Discrete simulation also offers the advantages of waiting time distributions and scaling for widely varying populations. The simulation was used to determine the optimum time to apply insecticide to reduce destructive pest stages. The sensitivity study found that the optimal time to apply insecticide was to several early stages of the first generation of the insect.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"33 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114122247","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, in large scale simulations this list often becomes cumbersome to maintain since the number of pending events may become quite large. As a result, the execution time required by the simple linked list is often a significant portion of total simulation time. Several articles have been published suggesting improved synchronization procedures. The most efficient procedures reported are the time indexed procedure and the two level procedure. Both methodologies are designed for use in languages such as PASCAL or Pl/l, and as a result neither algorithm translates well into FORTRAN. Further, both procedures require external parameter definition, which is a major handicap to their adoption by a general purpose language. This paper introduces a new synchronization procedure, the two list procedure, which is much faster than simple linked lists for large pending event files. This procedure was designed for implementation in FORTRAN, and properly implemented it is transparent to the user; thus it is ideal for adoption by general purpose simulation languages.","PeriodicalId":186490,"journal":{"name":"Annual Simulation Symposium","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1981-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114768600","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}
