    This paper presents a Petri net approach for the modeling of a CNC-milling machining centre. Next, by utilizing fuzzy logic with Petri nets (fuzzy Petri nets), a technique based on 9 fuzzy rules is developed. This paper demonstrates how fuzzy input variables, fuzzy marking, fuzzy firing sequences, and a global output variable should be defined for use with fuzzy Petri nets. The technique employs t...

    We present two methods to provide explanations for reasoning with belief functions. One approach, inspired by Strat's method, is based on sensitivity analysis, but its computation is simpler thus easier to implement than Strat's. The other approach is to examine the impact of each piece of evidence on the conclusion based on the measure of the information content provided by the evidence. We show ... View full abstract»

    The ability to manipulate previously unseen objects under visual control is one of the key tasks in the successful implementation of robotic, automated assembly and adaptive material handling systems. The automation of such complex industrial environments will require the development of machine vision systems that are highly adaptable and capable of dealing with a wide range of variable products. ...

    The two most essential fuzzy rule-based models used in the literature and in the industrial applications are briefly described. The way of reasoning in these models is shown. Interpolative reasoning for the case of sparse rule bases is also discussed. Rule base compression by eliminating redundant rules whose information can be reconstructed within a set accuracy interval from the remaining rules ... View full abstract»

    This paper presents a modeling technique that extracts judgments and decisions from experts to derive a consensual model for decision support. The proposed approach is applied to build a decision support system for the new product entry timing decision. Experience learned from the proposed methodology suggests that it is possible to: 1) capture consensual knowledge from a group of experts, 2) mode... View full abstract»

    A major complexity in the development of many computerized information systems is the lack of an integrated framework and analysis structure to consolidate disparate types of information. Successful information system development in complex environments requires an approach that supports development of systems across all information areas and uses the same model for analysis, specification, protot...

    This paper addresses an evolutionary process currently taking place in software engineering: the shift from hardware to software, where the role of software engineering is increasing and is becoming more central in systems integration. This shift also markedly affects the sources of risk that are introduced throughout the life cycle of a system's development-its requirements, specifications, archi... View full abstract»

    A systematic and unified approach which accomplishes performance monitoring, performance improvement and fault prediction in control systems is proposed. The feature vector which is a vector formed of the coefficients of the estimate of the sensitivity function and the influence matrix which is the Jacobian of the feature vector with respect to the physical parameter are shown to contain the relev...

    A connectionist inferencing network, based on the fuzzy version of Kohonen's model already developed by the authors, is proposed. It is capable of handling uncertainty and/or impreciseness in the input representation provided in quantitative, linguistic and/or set forms. The output class membership value of an input pattern is inferred by the trained network. A measure of certainty expressing conf... View full abstract»

  • A heuristic search approach for solving a minimum path problem requiring arc cost determination

    Two generalizations of A*, BA* and DA*, are presented and analyzed. Both consider the problem of finding a minimum cost path from the start node to a finite goal node set in a directed OR-graph, assuming that estimates of the optimal costs from each node to the goal node set are given (as described by the heuristic function), estimates of all arc costs are given, but the actual arc costs require d...

    This paper presents an exact linear inequality description of the posterior probabilities that arise from priors which satisfy a system of linear inequalities and which are revised by conditionals whose components fall within constant intervals. The posterior set is convex. The estimation of posterior intervals and other posterior functions is discussed View full abstract»

    A bimodal dial-a-ride problem (BDARP) considered in this paper is a dial-a-ride problem that involves two transportation modes: paratransit vehicles and fixed route buses. Riders in such a system might be transferred between different transportation modes during the service process. The motivation of this research is that by efficiently coordinating paratransit vehicles with fixed route buses we c... View full abstract»

    The emergence of new technology has enabled rapid data collection via mechanical interviews. Improved speed of data collection enables researchers to collect a larger volume of data with lower interview cost. Computers allow editing during data collection to prevent errors and they direct respondents to relevant questions. They may also facilitate immediate data tabulation and analysis. In spite o...

    This paper presents an approach to systems analysis and design called the operations-oriented methodology (OOM). It was developed with the objectives of being comprehensive in terms of scale and detail, easy to understand by a nonexpert and capable of formal analysis. The methodology was tested at seven field sites. The paper describes the fundamentals of OOM, and more particularly focuses on its ... View full abstract»
