These system designs must reflect operational requirements for maximum utilization of available resources and identify important parameters for consideration in future plans.","PeriodicalId":257203,"journal":{"name":"Proceedings of the 1967 22nd national conference","volume":"28 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132153155","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}

From its modest beginning in 1918, USASI has grown into a national federation of more than 138 technical societies and trade associations that are either member bodies or associate members. In addition, USASI has some 2200 company members. Within USASI, there are three sectional committees that work in the broad area of data processing standards. These are X3 (Computers and Information Processing), X4 (Office Machines), and X6 (Computers and Related Equipment). Each sectional committee usually has several subcommittees operating under its direction. For example, as shown in Figure 1, Sectional Committee, X3, has eight subcommittees which are X3.1 (Optical Character Recognition), X3.2 (Codes and Input/Output), X3.3 (Data Transmission), X3.4 (Common Programming Languages), X3.5 (Vocabulary), X3.6 (Problem Definition and Analysis), X3.7 (Magnetic Ink Character Recognition), and X3.8 (Data Elements and their Coded Representation). Subcommittee X3.3 (Data Transmission) has the following work scope: “Determine and define the operational characteristics governing the performance of digital data generating and receiving systems combined with communications systems.” To accomplish this work scope, X3.3 has six task groups operating under its direction (see Figure 2). One of these task groups, X3.3.4 (Control Procedures) is developing what are known as Data Link Control (DLC) procedures. These procedures will specify how data communications can be controlled by using the communications control characters provided in the coded character set known as the United States of America Standard Code for Information Interchange (USASCII).","PeriodicalId":257203,"journal":{"name":"Proceedings of the 1967 22nd national conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115406904","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}

Most storage-limited computer programs devote a major part of their available memory to the representation of functions of more than one variable: e.g., equation-of-state tables in physics problems,1 optimal return functions in dynamic-programming problems,2 routing tables in communications simulations,3 tables of manpower and material in simulations of military theatre operation,4 function representation in meteorological and astronomical investigations,5 and representation of topographic information. This paper develops and analyzes tabular methods with respect to the topographic representation problem. However, the result are presented in terms of general smoothness and accuracy parameters; thus, they also apply to the other problems mentioned above.","PeriodicalId":257203,"journal":{"name":"Proceedings of the 1967 22nd national conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114227449","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}

It does this by providing facilities for the user to interact with the computer so that they may both play active roles in the simulation process as it is occurring. Thus, the user may perform some of the simulation functions himself and the computer performs the remaining ones. Alternately, the user may act only as a monitor and observe, verify and record data or modify and redirect the simulation when it strays erroneously from the desired path.1,2,3 A second feature of an on-line simulation system is that it may allow the actual phenomenon being simulated to become a part of the simulation.","PeriodicalId":257203,"journal":{"name":"Proceedings of the 1967 22nd national conference","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131332950","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}

At that time, there were several systems in use by the airlines to present “yes-no” information on seat availability and in some cases maintain seat inventory counts. None of these systems, however, performed the complete “back-room” job of filing records, sending communication messages, processing wait-lists, preparing boarding manifests, etc. Significant improvements in passenger service were expected if the many possible sources of error in these operations could be reduced. The effort included development of specialized pieces of equipment and of a control program to interface between the application programs and the hardware. This was at a time when operating systems were just beginning to come into use. This paper concentrates upon the control program architecture, setting forth the important lessons that were learned after the system became operational.","PeriodicalId":257203,"journal":{"name":"Proceedings of the 1967 22nd national conference","volume":"309 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116257024","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}

Fortunately system designers are not waiting for a formal theory before experimenting. Unfortunately some of the results are so diverse in effectiveness that greater emphasis on analysis must be achieved. If predictability cannot lower the risks associated with the tremendous investments required to implement information processing utilities, progress in this field may be markedly decreased. The present paper presents a characterization of the time-sharing system environment, a set of measures associated with the system, an integrated summary of models and a discussion of measurements.
