The newly approved Institute of Electrical and Electronic Engineers IEEE Standard 1278, developed by DIS, results from a process of negotiated consensus achieved among a large body of participants. In this paper, an activity model documents the interactive procedures used by members of the DIS community to develop a family of standards. This effort was accomplished by following the Corporate Information Management (CIM) Functional Process Improvement (draft DoD 8020.1-M, January 1993). The \"as-is\" model provided the mechanism to clarify ambiguous areas and eliminate possible duplications. The \"to-be\" model was developed based upon the lessons learned and recommendations of the study.","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":"114128770","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}

Supply outages are inevitable but a key objective of management is that these be minimised in terms of frequency and duration. The problem of supply continuity is particularly acute in rural areas which are supplied from radial tail fed lines. Improvements can be achieved by major capital expenditure such as the addition of costly parallel lines, the inclusion of such aids as SCIs (Short Circuit Indicators) which speed up the location of faults, and additional telecommunications equipment. Also changes in the operating procedures used in locating faults and restoring supply can have a significant effect on customer down time and hence on supply continuity. The realistic prediction of the effect of improvements in capital equipment, additional control and monitoring devices and/or of changes in operating procedures on customer down time is of fundamental importance. This paper presents a detailed simulation approach which can be used in such predictions.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"132 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":"116906743","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}

Law in a general form prescribes the frame of possible behaviour of players in the domain regulated by it. A law can be considered as a set of rules forming a knowledge base and problems arising in the domain of its application should be answered based on it. In the last six years we developed a method to transform rules of law as it is published in statute--books into working expert systems. On the other hand simulation is the use of models to predict behaviour of existing or planned real system. If we consider the law as a model of the reality it is regulating, the corresponding expert system could be considered as the implemented version of this model on computers. Now by the use of these expert systems we can perform simulation. This simulation means the examination of the possible behaviour of the players which in some cases can be quantified by the use of statistical data. The method presented is particularly useful when one is framing new laws and wants to see the possible effects of the different proposed versions. Our method is mainly applicable for tax law, social security law, Finances Act or similar laws.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"113 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":"117292178","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}

Controlling processes in a Flexible Machining Cell is more difficult compared to conventional manufacturing systems. This is primarily due to the concurrent and asynchronous interaction of events which cause system deadlocks. An approach to model the controls of a cell for a given process specification is presented. Petri Nets was used as the modeling formalism. An algorithm is used to test the model for deadlock occurrences. The results obtained from this research indicates the scope for designing adaptive control procedures capable of on-line applications.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"153 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":"122876460","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}

These models should have the expressive power to represent the static and temporal relationships among data and they should have the capability to initiate actions to enforce these relationships when the application state is changed. Most commercial databases are passive, i.e., they do not take action or enforce a constraint when the data undergoes a state change. Object oriented database systems have taken the technology one step further by encapsulating operations with the data. In this paper we propose a data model for simulation which builds on object oriented and active database principles to represent physical systems in terms of its structure and function. This model is called the structure-function paradigm, or SF-paradigm for short.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"1 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":"130290254","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}

We use the simulator to test our scheme to partition a sequential program for parallel execution on a shared memory, asynchronous multiprocessor. The results of the simulations indicate that our partitioning scheme can provide significant speed-up by executing the program in parallel. We then execute the partitioned program on an actual multiprocessor and find a high degree of correlation between the simulations and the actual executions. This correlation serves to validate our simulator. We then use the multiprocessor simulator to hypothetically extended the actual multiprocessor and we show that adding more processors will not provide significant improvement in the parallel executions unless the communication structure is also improved to contain more parallelism.","PeriodicalId":177234,"journal":{"name":"Proceedings of 1993 Winter Simulation Conference - (WSC '93)","volume":"24 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":"121688655","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}
