In such a system each instance of execution runs identical code but with a different input data set. The main problem addressed is the choice of block selection policy, that is, the choice of which indivisible block of code to execute next. The authors investigate four block selection policies by simulating the execution of such a system. A stochastic flow-graph representation was chosen to model the execution of a simulation. A two-level block selection policy was found to have the best potential speedup of the four block selection policies. The speedup levels achieved were not large, and decreased when there are a large number of unique event types (and therefore handlers) in the simulated system.<<ETX>>","PeriodicalId":448258,"journal":{"name":"1991 Winter Simulation Conference Proceedings.","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125914370","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}

Informal arguments about the performance of each algorithm are made, and the arguments are confirmed through measurement of the bounded lag protocol using torus networks on a shared memory multiprocessor. Conservative-synchronous protocols are shown to be inherently efficient in the experiments considered; adding a termination algorithm requires limited additional memory and increases the wall clock time required for simulation by at most an amount proportional to the number of logical processes. Furthermore, a simulation model with any stable termination condition requires negligible overhead for the termination algorithm, a property that appears to be unique to synchronous protocols.<<ETX>>","PeriodicalId":448258,"journal":{"name":"1991 Winter Simulation Conference Proceedings.","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128154083","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 standard approach to preventing this is to project the sequence generated by the algorithm onto a predetermined compact set K. However, in the typical application, the approximate location of the solution is not known. To minimize the probability that the solution lies outside the set K, it is therefore necessary to let K be large. This can seriously curtail the efficiency of the algorithm. The author proposes a stochastic approximation algorithm which bounds the sequence of estimates of the solution to an increasing sequence of sets. This eliminates the possibility of bounding the algorithm to a set which does not contain the solution. Furthermore, it is possible to let the initial set be small, which can result in improved empirical performance.<<ETX>>","PeriodicalId":448258,"journal":{"name":"1991 Winter Simulation Conference Proceedings.","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132776204","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}

In addition, the simulation output series is batched and the corresponding batch means are used as observations in the FDM factor screening analysis. For a certain class of metamodels, steady-state results are provided. Results are also provided for batch sizes chosen to reduce serial correlation in output series, but not necessarily to achieve steady state. An example is presented which illustrates cases where fixed factor batching (FFB) improves the power of the FDM hypothesis test and cases where it does not. For cases where FFB is beneficial with respect to the power of the test, it is shown that batching to an intermediate batch size may be better than batching to achieve steady state.<<ETX>>","PeriodicalId":448258,"journal":{"name":"1991 Winter Simulation Conference Proceedings.","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123559260","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 simulation system integrated with an existing GIS to provide the user with the capability of accessing and managing the information transfer between the GIS and the simulation models is described. This integrated system need not be limited to simulation alone; other calculations which are essential for the traffic engineer can be integrated as well. For example, the calculation of highway capacity is a basic need of all traffic engineers. The software to perform these calculations can, itself, be integrated with the GIS system, traffic simulation, and animation. Such a system offers the engineer a capability that goes beyond analysis: the engineer can now perform designs of a system exploring alternative treatments to identify the most effective technique for improving traffic operations.<<ETX>>","PeriodicalId":448258,"journal":{"name":"1991 Winter Simulation Conference Proceedings.","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115165941","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}

One of the features of this scheduler is high-speed scheduling, which depends on the configuration of this system. The optimization algorithm determines the product sequence to be used in the shop. Then, a simulator determines each product flow based on the shop floor model and simple dispatching rules. The key point for high-speed scheduling is to reduce the complexity of simulation rules. The simulator has responsibility only for local optimization. A second feature of this scheduler is the scheduling algorithm which can handle multiobjectives. In a real factory, the due date has top priority for scheduling, but the lead time and machine utilization can be changed by production circumstances. In this scheduler, machine load leveling is used for shortening the lead time, and a higher load at a later process is used for increasing the machine utilization. An operator can assign the balance of lead time and machine utilization by setting a parameter. An application to a real shop floor is discussed.<<ETX>>","PeriodicalId":448258,"journal":{"name":"1991 Winter Simulation Conference Proceedings.","volume":"40 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122807912","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}
