Presents a formal model for specification of logical requirements of computer-based information systems that incorporates structural and dynamic aspects based on two separate models: the Logical Information Processing Structure and the Logical Information Processing Network. The model's role in systems development is discussed. (MBR)

A mathematical modeling technique has been developed to provide those having administrative responsibilities for establishing scientific and technical information systems with a flexible and powerful tool for making management decisions. A large number of factors (user communities, document forms, subject disciplines, etc.) are involved in…

The most time consuming and expensive step in developing expert systems is knowledge acquisition (KA), and it is important to determine how the limited resources for acquiring knowledge should be allocated across different sources. This paper develops a model that determines how KA resources should be spent and how such a model may be used. (23…

The Design of Training Systems (DOTS) project was initiated by the Department of Defense (DOD) to develop tools for the effective management of military training organizations. Phase 2 involved the design and development of three computer-based mathematical models, described in detail in this report. The models described are the System…

The Design of Training Systems (DOTS) project was initiated by the Department of Defense to develop tools for the effective management of military training organizations. Phase 2 of the project, from which this report emanates, involved the design and development of three computer-based mathematical models and their validation. Volume 1 presents…
