Full steady-state simulation programs

Complex flow-sheeting programs, that simulate the operation and a complete process, or individual units, have been developed by several commercial software organisations. The names of the principal packages available, and the contact address, are listed in Table 4.1. Many of the commercial programs have been made available by the proprietors to university and college departments for use in teaching, at nominal cost.

The method of Dantzig and Johnson et al. marked a breakthrough, both in the time required to solve chemical composition problems and in the complexity of problems that could be handled. Their method constituted the first version of what has become RAND s chemical composition program. Subsequently, refinements have been made in numerical techniques and human engineering, resulting in the present program. RAND mathematicians, notably H. E. Kanter, R. J. Clasen, N. Z. Shapiro, M. Shapley, and L. Cutler, have developed programs to simulate steady—state systems and certain types of transients. (See References for a full list of contributors...
