Philip J. Kiviat
Philip J. Kiviat (born October 15, 1937) is noted, along with Alan Pritsker, for half a century of work on computer simulation. Biography Kiviat studied at Cornell University from 1955-1961. While working from 1961-1963 for U.S. Steel Corporation he pioneered the development of the original GASP software, which was later enhanced by Alan Pritsker to form ''GASP II''. After moving to RAND Corporation in 1964, Kiviat worked with Harry Markowitz to produce SIMSCRIPT II. His subsequent work at the 1972-founded Federal Systems Integration and Management Center (FEDSIM) earned him recognition as "the simulation czar of the federal government." He is also known for the eponymous '' Kiviat Graph'' (also identified as a ''Kiviat diagram'', ''Kiviat chart'', ''Polar chart'' or Radar chart A radar chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point.

Computer Simulation
Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict. Computer simulations have become a useful tool for the mathematical modeling of many natural systems in physics (computational physics), astrophysics, climatology, chemistry, biology and manufacturing, as well as human systems in economics, psychology, social science, health care and engineering. Simulation of a system is represented as the running of the system's model. It can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions. Computer simulations are realized by running computer programs that can be either small, running almost instantly on small devices, or large ...

Cornell University
Cornell University is a private statutory land-grant research university based in Ithaca, New York. It is a member of the Ivy League. Founded in 1865 by Ezra Cornell and Andrew Dickson White, Cornell was founded with the intention to teach and make contributions in all fields of knowledge—from the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's founding principle, a popular 1868 quotation from founder Ezra Cornell: "I would found an institution where any person can find instruction in any study." Cornell is ranked among the top global universities. The university is organized into seven undergraduate colleges and seven graduate divisions at its main Ithaca campus, with each college and division defining its specific admission standards and academic programs in near autonomy. The university also administers three satellite campuses, two in New York City and one in Education City, Qatar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GASP (simulation Language)
GASP, GASP II and GASP IV are FORTRAN-based simulation languages. GASP stands for General Activity Simulation Program. SLAM (Simulation Language for Analogue Modelling) is a simulation language based on Fortran and GASP. GASP Work on the original GASP project was done by Philip J. Kiviat at U.S. Steel Corporation, and was gearedto use on small to medium size computers with FORTRAN II compilers. Like SIMSCRIPT (conceived in 1962), there are developmental links of GASP (1964) at RAND Corporation The RAND Corporation (from the phrase "research and development") is an American nonprofit global policy think tank created in 1948 by Douglas Aircraft Company to offer research and analysis to the United States Armed Forces. It is financed .... While one of the ''RAND'' principals conceded that "GASP cannot compete with SIMSCRIPT" the same person praised GASP's strength: that it "serves well those who have only a small machine or who use several computers with no common language ...

SIMSCRIPT
SIMSCRIPT is a free-form, English-like general-purpose simulation language conceived by Harry Markowitz and Bernard Hausner at the RAND Corporation in 1962. It was implemented as a Fortran preprocessor on the IBM 7090 and was designed for large discrete event simulations. It influenced Simula. Though earlier versions were released into the public domain, SIMSCRIPT was commercialized by Markowitz's company, California Analysis Center, Inc. (CACI), which produced proprietary versions SIMSCRIPT I.5 and SIMSCRIPT II.5. SIMSCRIPT II.5 SIMSCRIPT II.5 was the last pre-PC incarnation of SIMSCRIPT, one of the oldest computer simulation languages. Although military contractor CACI released it in 1971, it still enjoys wide use in large-scale military and air-traffic control simulations. :''SIMSCRIPT II.5 is a powerful, free-form, English-like, general-purpose simulation programming language.

Radar Chart
A radar chart is a graphical method of displaying multivariate data in the form of a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point. The relative position and angle of the axes is typically uninformative, but various heuristics, such as algorithms that plot data as the maximal total area, can be applied to sort the variables (axes) into relative positions that reveal distinct correlations, trade-offs, and a multitude of other comparative measures. The radar chart is also known as web chart, spider chart, spider graph, spider web chart, star chart, star plot, cobweb chart, irregular polygon, polar chart, or Kiviat diagram. It is equivalent to a parallel coordinates plot, with the axes arranged radially. Overview The radar chart is a chart and/or plot that consists of a sequence of equi-angular spokes, called radii, with each spoke representing one of the variables. The data length of a spoke is proportional to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
