This paper deals with basic properties of lattices of structure models. The form of models considered here is used in at least three areas: reconstructabilily analysis, analysis of contingency tables, and relational and probabilistic database design. The fact that the set of all models is structured as a lattice has been part of the basic formulati...

An important problem in reconstructability analysis, and modelling in general, is determination of the set of simplest models, all of which acceptably represent the information contained in a given overall system. Evaluation of these models depends on acceptability (semantic) criteria and structural criteria. Structural criteria determine whether o...

Reconstructability analysis is defined as the process of investigating the possibilities of reconstructing properties of overall systems from the knowledge of the corresponding properties of collections of their various subsystems. In two recent papers, sets of procedures were presented which developed solutions of two problems associated with this...

Reconstructability analysis is viewed as a process of investigating the possibilities of reconstructing desirable properties of overall systems from the knowledge of the corresponding properties of their various subsystems. The reconstructability analysis consists of procedures for generating meaningful reconstruction hypotheses, procedures for the...

In Physics and Philosophy the Nobel Prize-winning physicist, Werner Heisenberg (1968), argues that one of the most important features of modern physics has been to instigate the development of a “really different attitude toward the problem of reality.” This different attitude is one that forces a reexamination of the tenability of a view toward sc...

The study of varying forms of conflict within nations has long been an important area of focus from within political science. The orientation of much of this research has been on intensive study of single aspects of individual cases or on comparison of one of these aspects — such as revolution — over a small number of cases. In the last decade or s...

From the beginning, the systems research movement has shown a high potential for offering a conceptual framework for the understanding of social systems. Much of this potential has been realized, but a major gap remains with regard to operational investigative aids. Developments of the last ten years with a method­ ological orientation and emphasis...

This paper is the second of three which provide a comprehensive framework and computer-implementable algorithms for the investigation of the relation between parts and wholes. Such investigation involves either the problem of determining from among all possible collections of subsystems of a given overall system those which allow the reconstruction...

The purpose of reconstructability analysis is to provide systems investigators with useful methodological tools for dealing with the various questions regarding the relationship between overall systems and their various subsystems. The term “system” is viewed in reconstructability analysis as a characterization of certain type of fuzzy measures by...

This paper provides a general framework within which to describe a major class of problems related to structure identification or determination. This framework is expressed in a manner which facilitates the development of working methods which operationalize the notion of structure for use in the investigation of systems.

Reconstructability analysis is viewed as a process of investigating the possibilities of reconstructing desirable properties or overall systems from the knowledge of the corresponding properties of their various subsystems. Overall systems are represented by n-dimensional relations, each of which is viewed as a finite set of aggregate states (n-tup...

One of the main points of the last chapter was the impossibility of removing all traces of a knowing subject (and the history of the subject and the state of the subject at the time of knowing). Closely related to this is the importance of themes which affect this knowing indirectly in that they pertain more properly to the cultural group and to th...

The influences which have affected the development of cybernetics and the general systems movement have also played an important role in science and thought which is less connected to a technological orientation. These similar developments, involving the recognition of the importance of structure, are reflected in the especially European movement o...

An important factor which must be considered in the development to this point is the relatively short period of time that the need for a general systems methodology has been properly articulated. A main consequence of this is that there does not exist the generally agreed to common language which is our main concern. This is of course compounded by...

To develop an appreciation for the role of general systems methodology in respect to the social sciences, it is necessary to trace some aspects of their development, and also to examine the status of certain methodological questions within them. By observing a page (or several fragments of several pages) of the history of science, we find that in t...

In the last chapter we presented the basic concepts of the overall framework associated with preliminary aspects of an investigation.

A conceptual framework is presented in this paper within which it is possible to integrate and operationalize results of systems research. The framework is described in terms of an interactive general systems problem solver (GSPS). The paper consists of a discussion of both the motivation for developing GSPS and its implications, and a formal descr...

The recent orientation of our research—and that of the group with which we work at the School of Advanced Technology—has been directed toward a not unfounded reservation which we occasionally encounter and which is succinctly represented by Bunge’s observation that “...some scientists have misgivings because GST’s have not delivered all the goods p...

As part of an earlier presentation to this congress Cavallo and Klir characterized the situation regarding the role of general systems research with respect to the social sciences. Fundamental to their presentation was an attitude toward epistemology and science which places primary emphasis on the process-related aspects of research and knowledge...

A method is presented for computing the number of elements in any collection of sets derived from other sets by statements that are reducible to conjunctions, disjunctions, and complementations. The technique also detects certain inconsistencies that may be present in the given data. The method is applicable to a wide range of problems in computer...

This paper considers systems methodology, using computer-oriented mathematical concepts, in terms of two empirical examples from sociology: suicide and the schooling process. We apply to the two areas two algorithms developed a-s tools for the study of binary relations and the set covering problem. The illustrations are intended to emphasize the po...
