This paper describes a configurational and mathematical tool that may be used in the planning and scheduling of a research program The configuration, termed a decision box (db) network, is a generalization of the PERT network and allows alternative procedures for accomplishing research tasks to be considered The probability of following each alternative is estimated, leading to a ranking, in terms of proability of occurrence, of the possible outcomes of the research program The entropy of the process is calculated using classical information theory concepts Standard PERT techniques for time estimating and scheduling, superimposed upon the db network structure, complete the description of this research management tool.

    The notion of critical path is a key issue in the temporal analysis of project scheduling in deterministic setting. The very essence of the CPM consists in identifying the critical path, i.e., the longest path in a project network, because this path conveys information on how long it should take...
