Abstract:

A methodology to analyze, model, and evaluate decision-making processes that require coordination is presented. The concept of a team of decision-makers and the issues of inconsistency of information and synchronization are emphasized. Predicate Transition Nets are used as the basic technique to represent organizational structures. Two measures of coordination are introduced the degree of information consistency and the measure of synchronization. The simulation of Petri Nets is presented as a means of investigating the dynamics of decision-making processes requiring coordination. A model of decision support systems DSS is developed. An example of a two-person hierarchical organization aided by a DSS is given as an illustration The accuracy, time delay and synchronization are computed. The results are that decision aids can alter the coordination of decision-making organizations by modifying the priority order with which information is processed, and by increasing the number of information flow paths with different processing times.
