The development and evaluation of an improved genetic algorithm based on migration and artificial selection

Much research has been done in developing improved genetic algorithms (GAs). Past research has focused on the improvement of operators and parameter settings and indicates that premature convergence is still the preeminent problem in GAs. This paper presents an improved genetic algorithm based on migration and artificial selection (GAMAS). GAMAS is an algorithm whose architecture is specifically designed to confront the causes of premature convergence. Though based on simple genetic algorithms, GAMAS is not concerned with the evolution of a single population, but instead is concerned with macroevolution, or the creation of multiple populations or species, and the derivation of solutions from the combined evolutionary effects of these species. New concepts that are emphasized in this architecture are artificial selection, migration, and recycling. Experimental results show that GAMAS consistently outperforms simple genetic algorithms and alleviates the problem of premature convergence. >

A methodology to model the functional structure of an organization

Abstract The Integrated Computer Aided Manufacturing (ICAM) program of the U.S. Air Force identified a need to better communicate and analyze manufacturing for the people involved in improving productivity. To satisfy that need, the ICAM program developed the IDEF (ICAM Definition) method to address particular characteristics of manufacturing. This IDEF Method is equally applicable in analyzing other types of organizations. IDEF comprises of three modeling methodologies: Function model methodology (IDEF 0 ), Information model methodology (IDEF 1 ) and Dynamics model methodology (IDEF 2 ). This paper reports on the function model methodology only. This methodology is used to construct a function model which helps in understanding the actions, activities, decisions, and informational interfaces needed to support the functions of an organization.

Determining an organization's information requirements: a state of the art survey

The issue of information requirements of an organization and their specifications span two isolated territories. One territory is that of organization and management and the other belongs to technicians. There is a considerable gap between these two territories. Research in requirements engineering (technicians side) has primarily concentrated on designing and developing formal languages to document and analyze user requirements, once they have been determined. This research has ignored the organizational issues involved in information requirements determination. Research in the field of organization and management has addressed the organizational issues which affect information requirements of an organization. Various frameworks reported in the literature provide insights, but they cannot be considered as methods of determining requirements. Little work has been done on the process of determining requirements. This process must start with the understanding of an organization and end with a formal specification of information requirements. Here, it is worth emphasizing the fact that the process of determining and specifying information requirements of an organization is very different from the process of specifying design requirements of an information system. Therefore, program design methodologies, which are helpful in designing a system are not suitable for the process of determining and specifying information requirements of an organization.This paper discusses the state of the art in information requirements determination methodologies. Excluded are those methodologies which emphasize system design and have little to offer for requirements determination of an organization.

A computational model for financial reporting fraud detection

A computational fraud detection model (CFDM) was proposed for detecting fraud in financial reporting. CFDM uses a quantitative approach on textual data. It incorporates techniques that use essentially all of information contained in the textual data for fraud detection. Extant work provides a foundation for detecting deception in high and low synchronicity computer-mediated communication (CMC). CFDM provides an analytical method that has the potential for automation. It was tested on the Managements Discussion and Analysis from 10-K filings and was able to distinguish fraudulent filings from non-fraudulent ones. CFDM can serve as a screening tool where deception is suspected.

A comprehensive agent-based architecture for intelligent information retrieval in a distributed heterogeneous environment

The Internet has become the global infrastructure supporting information acquisition and retrieval from many heterogeneous data sources containing high-speed text and rich multimedia images, audio, and video. AgentRAIDER is an ongoing research project at Texas Tech University designed to develop a comprehensive architecture for an intelligent information retrieval system with distributed heterogeneous data sources. The system is designed to support intelligent retrieval and integration of information from the Internet. Current systems of this nature focus only on specific aspects of the distributed heterogeneous problem such as database queries or information filtering. Consequently, these concepts and others have never been successfully integrated into a unified, cohesive architecture. This paper discusses the design and implementation of the AgentRAIDER system and identifies areas for applications of the system in various domains.

The development of an adaptive decision support system

The squeeze of two opposed paper-receiving rolls of an offset printing press may be infinitely adjusted within a relatively small range by virtue of the fact that each end plate supporting the rolls has a slit therein between the axes of rotation of the rolls which will permit slight deformation of the plate in a direction transversely of the slit upon manipulation of an adjusting mechanism to shift the rolls toward and away from each other. Adjustment mechanism is provided on each plate and includes a cam that, when rotated by the longitudinal displacement of an operating link, has the effect of opening or closing a corresponding slit to thereby effect minute adjustment of the spatial relationship of the roll axes. The operating link has a specially threaded section from which the longitudinal displacement of the link is derived, the arrangement being such that the ratio of link rotation to link displacement is relatively high so that very fine adjustment of the critical roll relationship can be achieved.

The process of research investigations in artificial intelligence-a unified view

A number of research communities recognize artificial intelligence (AI) as a valid reference discipline. However, several papers have criticized AIs research methodologies. This paper attempts to clarify and improve the methods used in AI. Definitions are proposed for terms such as AI theory, principles, hypotheses, and observations. Next, a unified view of AI research methodology is proposed. This methodology contains a long term dimension based upon the scientific method and an individual project dimension. The individual project dimension identifies four strategies: hypothetical/deductive, hermeneutical/inductive, case-based, and historical analysis. The strategies differ according to how prototyping is used in an experiment. >

A methodology to model the dynamic structure of an organization

Abstract The Integrated Computer Aided Manufacturing (ICAM) program of the U.S. Air Force identified a need to better communicate and analyze manufacturing for the people involved in improving productivity. To satisfy that need, the ICAM program developed the IDEF (ICAM Definition) method to address particular characteristics of manufacturing. This IDEF Method is equally applicable in analyzing other types of organizations. IDEF comprises of three modeling methodologies: function model methodology (IDEF 0 ), information model methodology (IDEF 1 ) and dynamics model methodology (IDEF 2 ). This paper reports on the dynamics model methodology only. This methodology is used to construct models which help in understanding the Dynamic (time-varying behavior) structure which the functions of an organization exhibit.
