In this paper, it is supposed that a project can be shown as a metagraph. The duration of activities are discrete random variables with known probability function, also one kind of consumable and constrained resource is required to execute each activity of the project.The objective of this paper is to maximize the probability of completion of stochastic metagraph before the due date of the proj...

Problem statement: In this study researchers propose a new fuzzy graph theoretic construct called fuzzy metagraph and a new method of clustering finding the similar fuzzy nodes in a fuzzy metagraph. Approach: We adopted T-norms (Triangular Norms) functions and join two or more Tnorms to cluster the fuzzy nodes. Fuzzy metagraph is the fuzzyfication of the crisp Metagraphs using fuzzy Generating ...

This paper proposes a Fuzzy Metagraph based Knowledge representation of Decision Support System (DSS). This system will help users to make correct decision with very low risk. Fuzzy Metagraph is an emerging technique widely used for real world applications. Fuzzy Metagraph is used to form the rule base to support inference system to make correct decision. This method can be used in many real wo...

Metagraphs are graphical hierarchical structure in which every node is a set having one or more elements. Fuzzy Metagraph and Vague Metagraph are an emerging technique used in the design of many information processing systems like transaction processing systems, Decision Support Systems (DSS), and workflow Systems. In this paper, distinct matrixes have been proposed for Fuzzy Metagraph and Vagu...

Fuzzy metagraph is an emerging technique used in the design of many information processing systems like transaction processing systems, decision support systems, and workflow systems. Very often, even a carefully chosen graph data structure could be improvised to provide more efficiency in terms of time complexity or space complexity or both. In this paper, a well-designed fuzzy metagraph is pr...

A metagraph is a graph-theoretic construct that has been shown to be a useful basis for graphical visualization and algebraic analysis of DSS resources such as models, data and rules. In this paper, we describe the structure and use of a metagraph-based DSS analysis workbench that can also be used as a front-end to an existing DSS for activities such as database design and model analysis.

This paper proposes an efficient algorithm for Fuzzy based Metagraph ADT (Abstract Data Type). It is a hierarchical data structure where every node has one or more data. A mathematical model which encompasses both data type and the functions that operate on the data type is called as an ADT. Fuzzy set ADT integrated with Fuzzy Metagraph can perform different operations such as Union, Intersecti...

A metagraph is a graph formalism that can be used to model the different components of a DSS and to analyre the interactions among them. One such component is a knowledge based system (KBS) in which domain knowledge is stored ss if-then rules. In addition to such rules, a KBS can also contain a set of integrity constraints, which are used to manage the rule base both duringnpdatesand problem so...

Network embedding in heterogeneous information networks (HINs) is a challenging task, due to complications of different node types and rich relationships between nodes. As a result, conventional network embedding techniques cannot work on such HINs. Recently, metapathbased approaches have been proposed to characterize relationships in HINs, but they are ineffective in capturing rich contexts an...
