Preface to the special issue on Meta-System Transition Theory
Consideration of the application of possibilistic systems theory to the model-based diagnosis of the faults of a spacecraft system: fault and behavior models as possibilistic automata; fault hypotheses and prediction errors with possibilistic weights; possibilistic distance of telemetry from predicted and nominal state. Consideration of sensor failure modeling and indirect and redundant measurements in evidence theory.
Semantic analysis of entropy; syntactic vs. semantic definitions of entropy; type-specificity of entropy measures; the origin and identification of emergent levels in physical systems; and the ontological status of non-thermodynamic entropies.
Towards distance measures in quantified semantic hierarchies.
Survey of some of the most prominent GIT formalisms in the context of classical approaches, including probability theory. Introduction of the formal specifications of a range of theories; interval analysis and probability theory; generalization to fuzzy systems theory; monotone or fuzzy measures; random sets and Dempster-Shafer structures; possibility theory.
Consideration of the possible relations between the classes of living and control systems in terms of extensional and ontological necessity and sufficiency.

(Selected for publication in the select proceedings of the 1994 Computer-Aided Systems Theory Conference) Design for C++ classes for random sets, probability and possibility distributions, and possibilistic processes.

Definition of systems theory and systems analysis.
Arguments to support the position that possibility is related to, but distinct from, both fuzzy and probability theory: the role of normalization in articulation of a "regular" view of possibility; alpha cuts and focal elements; the role of the maximum operator.
(Selected for publication in the select proceedings of the 1993 Computer-Aided Systems Theory Conference) Possibilistic automata as pessimistic fuzzy automata which are normal in the sense of general automata; properties of possibilistic automata;possibilistic automata are identical with strongly consistent stochastic automata.
(Invited paper) Normal possibility distributions are available for consistent random sets, and a set of focused consistent transformations is available for inconsistent random sets. The Principle of Uncertainty Invariance is modified to provide a method which selects that consistent transformationwith Minimal Information Distortion from the measured random set.
Distributed representation for taxonomic ontologies, lattice theoretical analysis to gaurantee validity and identify inconsistencies in the inheritance structure.

From network analytical to link analytic approaches, focusing on smaller graphs with heterogeneous link types; chaining of views of multidimensional databases; connections to virtual world architectures.
Introduction of Monte Carlo approach to smapling a functionally propagated general random sets; bounding and convergence properties.
Normal possibility distributions are available for consistent random sets, and a set of focused consistent transformations is available for inconsistent random sets. The Principle of Uncertainty Invariance is modified to provide a method which selects that consistent transformationwith Minimal Information Distortion from the measured random set.
Identification and measurement of degree of intelligence in systems; hierarchical and anticipatory control relations.
Constraints from virtual physics, common communication structures, and shared knowledge on the decision-making capabilities semiotic agents.
An approach to agent modeling of socio-technical organizations on semiotic principles; semiotic agents as decision-making entities embedded in artificial environments exchanging semiotic tokens.
Overview of possibilistic systems in an imprecise probabilities context.
Evolutionary systems in the context of this community of interaction: 1) a coupled interaction between a system and its environment; 2) an environment with sufficient initial richness and structure to allow for; 3) embodied emergent classification of that environment-system coupling; 4) which is subject to pragmatic selection.

Extended abstract: fuzzy measures with distributions; random set completion and structural and numerical aggregation functions; probabilistic, possibilistic, and ring-structured cases.
Consideration of the application to the model-based diagnosis (MBD) of the faults of a spacecraft system: fault and behavior models as possibilistic automata; fault hypotheses and prediction errors with possibilistic weights; possibilistic distance of telemetry from predicted and nominal state. Consideration of sensor failure modeling and indirect and redundant measurements in evidence theory.
Possibilistic histograms, their interpretation as fuzzy numbers, and their continuous approximations.
Towards development of a strictly possibilistic semantics of natural systems: the semantics of possibility statements in relation to modal logic, natural language, and mathematical possibility; strong consistency relation for probability and possibility; the application of possibility theory to complex systems.
Set-based statistics to generate possibility distributions from measured data; physical measurement methods to generate statistical data.
An empirical measuring procedure which yields data governed by possibility theory. Set-based statistics are used to generate empirically derived random sets. Normal possibility distributions are available for all consistent random sets, and a set of ``consistent transformations'' are available for all inconsistent random sets. The Principle of Uncertainty Invariance is used in a modified form to select the consistent transformation with minimal information loss from the original random set.
