An environmental decision model for dynamic planning

In the complex, rapidly changing environment facing the modern business enterprise, it has become increasingly difficult to make meaningful predictions concerning future activities. As such, it is especially important for the decision maker to seek means of gathering and evaluating information. Due to the immense amounts of subjective data, the need arises for the development of valid techniques for identifying and quantifying relevant information.Writers in the area of organization theory have emphasized the importance of the relationship between and organization and processes occurring within its environment to the extent that these environmental processes and their impact are considered vital to the ultimate survival of the firm. The Graphical Evaluation and Review Technique (GERT) is an analytical process upon which simulation models can be developed to examine the effect of more sophisticated information processing. The GERT technique serves as an input to decision making and for purposes of analysis will be studied under conditions of the disturbed reactive environment.The essential method upon which this study is based is the development of a model designed to capture the characteristics of the environment. The model in turn is tested under various conditions and changing sets of information to arrive at some idea of the possible implications for decision making under a situation affected by more and different information usage.
