Abstract:

The report presents derivation, documentation, and listing of a dynamic programming model on JOSS FOR FINDING OPTIMAL SOLUTIONS minimum-cost paths to network problems. The network represents the possible connections between decisions and expresses costs of going from one to another. The model encompasses a value-iterative algorithm which successively converges to the solution. The principle of optimality, which permits finding the minimum-cost shortest path as a function of the maximum number of arcs allowed, is Regardless of how a particular state was arrived at, the remaining decisions as to what path to take enroute to the terminal must themselves constitute an optimal solution. The costs of traversing arcs may be input, recalled from other files, or calculated by JOSS from input functions. Model flexibility allows for testing the sensitivity of a decision process to changes in the terminal point.
