Modeling with Microcomputers.
Litaker, R. Gregory
The applications of a recently developed computer program for microcomputers in developing models in an institutional research environment are considered. The VISICALC program requires no user programming skills, is available for all major brands of microcomputers, and provides for easy exchange of information between users of different computing equipment. Computer modeling consists of the analysis of conditions or situations with the purpose of defining the essential elements, their interrelationships, and methods by which to relate the elements mathematically. After the relationships are established, various elements of the model can be manipulated to observe the changing outcomes. An example of modeling might be to develop a system that will provide tuition revenue estimates. By establishing a model of how tuition income is generated, one can observe the impact of changes in the variables that determine tuition income. The variables that control tuition income would be defined (e.g., full-time/part-time student mix, tuition rates, and college and school enrollments). Using the microcomputer, one can change the undergraduate enrollment figure and see its impact on expected income from tuition. VISICALC can take a problem that an individual would manipulate in a column-and-row format and transform it into a worksheet of up to 63 rows and 254 columns. Creating models involves typing headings and columns and entering formuli. VISICALC performs all arithmetic and transcendental functions and has a number of special functions. Background information concerning the origin of microcomputers is noted. (SW)
