    A complete analysis of any data-processing system, including a time-sharing system, must consider two fundamental questions: (1) What functions arc given the users of the system? (2) How are the resources that are used in implementing these functions controlled, allocated, and assigned? The word “functions” includes the number, convenience, and logical flexibility of the programming ... View full abstract»

    The IBM 2938 Array Processor together with its access method (APAM) increases the processing power of SYSTEM/360 Models 44, G5, and 75 for operations on vectors and matrices. The auxiliary processing capabilities discussed have proved especially useful in such areas as seismic exploration, vibration analysis, turbulence research, and image enhancement. Because of the modular design of the present ... View full abstract»

    The purpose of this paper is to describe a pseudo-random number generator that uses the full capacity of the 32-bit registers of IBM SYSTEM/360 computers, and to briefly report on and document the testing of and experience with the random number generator. The generator is a particular case of the sequence of numbers xi generated by the equation xi+1 = Axi (mod p) ... View full abstract»

    Some of the earliest applications of operations research techniques were made in the field of transportation. Until recently, however, little was done within the railroad industry. This paper describes an application of network flow analysis to onc problem of that industry: empty freight car allocation. Other modes of transportation may benefit from the Same analysis and the algorithm developed he... View full abstract»
