“…It allows a consideration of all interrela tionships simultaneously, and forms a bridge to the use of high- After constructing a mathematical model for an operations research or systems analysis study, a mathematical technique must be selected to derive a solution. Reeser (1972) classified these techniques as shown in Table 4. He also classified them as being either algorithmic, of which linear programming is an example, or heuristic, examples being the various simulation techniques.…”
