Using well-known modeling paradigms and existing computer-based tools, we show how to rapidly model and analyze complex work structures to improve throughput and resource utilization. The specification of a work flow is done using IDEFO (SADT), extended with behavioral details. We have developed a program (Work Flow Analyzer) that processes the resulting model to automatically generate a Colored Petri Net (CP-net) complete with the logic for loading input files and printing reports about processing bottlenecks and idle resources. This greatly reduces the cost and time to use simulation.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130586074","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}

Information theory, through use of the conditional entropy functional, provides a non- parametric approach to qualitatively assessing the sensitivity of the distributional relationships of the input and output processes of a simulation model. Since the conditional entropy functional quantifies the amount of uncertainty in the distribution of a set of random variables, it can be used as the basis for a methodology to assess the relative strengths of the statistical dependencies among the input/output processes. The application of information theory in this paper focuses on assessing the uncertainty in the simulation output processes attributable to the simulation input processes. This approach to sensitivity analysis is illustrated by an example.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123993634","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}

Detailed models have been constructed for studying feeder setup and chip placement operations. This software tool can be used for estimating the production cycle time for a particular set of boards and for evaluating the impact of various production policies on a surface mount factory's throughput. Following some introductory comments regarding the need for developing a tool such as SMT Sim, this paper presents an overview of the functional elements of the software, i.e., the routines for managing input data, outputs, and process models. The object-based code libraries of the SMT Sim software are also discussed. Use of the software is explained by means of an example simulation run, from build plan to simulated production report. Two types of applications are addressed: benchmarking setup procedures and analyzing assembly cost.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121213344","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}

SFSI utilizes the data acquisition system to detect any shop-floor problem, and to update and initialize simulation models to the current shop-floor status. SFSI can process the simulation model, determine its initial conditions' requirements, retrieve the required information from the data acquisition system, and update the simulation model. This allows the simulation to start with exact current system conditions eliminating the need for time consuming warm-up periods, thus improving the system's accuracy and real-time performance.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114870912","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}

Various tasks involved in managing exceptions, the times at which these tasks are to be performed, and their impact on the performance of a supervisory controller are studied. Online simulation methodology is utilized to detect, classify, and handle exceptions. A synchronization procedure, an essential step to perform online control using a discrete-event simulation language, is developed. Its main purpose is to resolve discrepancies between the behavior of entities and resources in the simulation model and shop floor. The framework is restricted to manufacturing cells; however, it can easily be extended to manage exceptions in logistics and distribution systems. A simulation model of a flexible manufacturing cell is used to illustrate exception detection and synchronization concepts.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127725009","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 number of conservative and optimistic algorithms have been proposed and studied for parallel simulation. We examine the problem of transparent execution of a simulation model using conservative algorithms, and present experimental results on the performance of these transparent implementations. The conservative algorithms implemented and compared include the null message algorithm, the conditional-event algorithm, and a new algorithm which is a combination of these. We describe how dynamic topology can be supported by conservative algorithms. Language constructs to express lookahead are discussed. Finally, performance measurements on a variety of benchmarks are presented, along with a study of the relationship between model characteristics like lookahead, communication topology and the performance of conservative algorithms.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124170874","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}
