The rapid development of micro-electronics towards multiterminal structures demands corresponding growth in understanding the potential and limitations of multiterminal devices and networks. The increasing sophistication of integrated circuits will impose a new set of criteria upon network synthesis.

Computers are being used to a rapidly increasing extent, to manipulate and to generate materially, mechanically. (1) Many applications simply require items of information to be selected from a file of fixed format, heavily abbreviated records, and expanded into statements that are self-explanatory, and used perhaps in individual communications or incorporated in computer typeset compendia. At the other end of the spectrum are the interrelated challenges of mechanical indexing, abstracting, and translation. The burgeoning applications of computers to publishing, education, library work and information services in most major branches of science and scholarhsip are leading to a host of text processing and generating problems that span these limits of complexity.

The Instititute of Management Sciences (TIMS) and the Washington Operations Research Council (WORC) co-sponsored two meetings in the early months of 1968 in the Rayburn Building on Capitol Hill. In these meetings, these professional associations held what was probably the first dialogue between the Management Science community and Representatives of the U. S. Congress. The Representatives were Congressman Robert McClory of Illinois and Congressman F. Brad-ford Morse of Massachusetts.

In an earlier paper we attempted to set forth (1) a design methodology for computer systems which made heavy use of simulation and (2) a simulation language intended to facilitate the use of the design methodology presented. The basic justification for the design methodology presented an old precept from engineering design: a problem must be defined before it is solved. The result was a methodology which laid great stress on specifying the behavior of a system or a component in a system before producing the design. The simulation language, SODAS, was designed to allow a design to proceed in a hierarchical way, treating any system as a set of components, specifying the behavior of those components, then treating the components themselves as systems. By means of the SODAS language it was to be possible to evaluate the design at any stage in its development without excess effort.

With the advent of the higher-level algebraic languages, the computer industry expected to be relieved of the detailed programming required at the assembly-language level. This expectation has largely been realized. Many systems are now being built in higher-level languages (most notably MULTICS).

The communications characteristics of multiaccess computing are generating new needs for communications. The results of a study of multiaccess computer communications are the topic of this paper. The analyses made are based on a model of the user-computer interactive process that is described and on data that were collected from operating computer systems. Insight into the performance of multiaccess computer systems can be gleaned from these analyses. In this paper emphasis is placed on communications considerations. For this reason, the conclusions presented deal with the characteristics of communications systems and services appropriate for multiaccess computer systems.

On-line computing systems are a relatively recent development in commercial computer technology. Most of the experience to date with the use of such systems has been gained at universities, large governmental organizations and a few pioneering businesses like American Airlines, Westinghouse and Keydata Corporation. Today, from the literature and recent announcements of computer plans, it appears that online systems are ready to be implemented in many organizations to perform a large variety of tasks. There are experts predicting that by 1970 the majority of computer systems sold will be performing some online functions. Huge growth is expected to occur in computers capable of operating on an on-line or time-shared basis.

Simulation of physical systems using digital computers has been accomplished by many people over the past few years. One such simulation program at Cornell Aeronautical Laboratory, Inc. constitutes an analytical representation of an automobile as it departs from the highway under various environmental conditions, especially under adverse ones where there is danger of collision with obstacles. As with most complex simulation programs where there are interactions among many components, the equations of motion, including the required restraints, become long and numerous. But foremost, the output data set in printed form is quite extensive and very difficult for the investigating engineer to completely comprehend. About thirty crowded pages of output are printed for a five second automobile test run.

This paper describes the mathematical formulation of a class of three-dimensional surfaces parametrically represented for efficient computer display. The degrees of freedom in the representation are such as to provide a rich variety of surfaces with convenient parameters for manipulation and constraint satisfaction. Historically this work began as an investigation of the properties of rational parametric cubics, a class of curves well-suited to the Harvard three-dimensional display. The desire to represent curvilinear surfaces in terms of these curves and an introduction to the Coons' surface formulation were sufficient to suggest the approach discussed here.

There is a growing need for data exchange, particularly the passing of files of data between programs that were produced independently. This will be needed in the development of computer networks and data bases; for example, a head office installation collecting files from various divisions of a corporation to build a data base. Both the development of formal and informal computer networks as well as the economic feasibility of large data bases are favoring the development of arrangements for a considerable volume of data exchange, whether directly over communication systems or by the dispatch of reels of tape and boxes of cards. These are very significant areas of growth that are just beginning to emerge in commercial EDP and are already creating problems within the Federal government.
