Bayesian Networks (BNs) are effective tools for providing decision support based on expert knowledge in uncertain and complex environments. However, building knowledge-based BNs is still a difficult task that lacks systematic and widely accepted methodologies, especially when knowledge is elicited from multiple experts. We propose a novel method that systematically integrates a widely used Multi Criteria Decision Making (MCDM) approach called Decision Making Trial and Evaluation Laboratory (DEMATEL) in BN construction. Our method elicits causal knowledge from multiple experts based on DEMATEL and transforms it to a BN structure. It then parameterizes the BN by using ranked nodes and evaluates its robustness and consistency by using sensitivity analysis. The proposed method provides a practical and generic way to build probabilistic decision support models by systematically exploiting expert knowledge. Suitable applications of this method include decision problems with multiple criteria, high uncertainty and limited data. We illustrate our method by applying it to a supplier selection case study in a large automobile manufacturer in Turkey.

Using operational data for decision making a feasibility study in rail maintenance Marsh, William; Nur, Khalid; Yet, Barbaros; Majumdar, Arnab (2016-05-01) In many organisations, large databases are created as part of the business operation: the promise of ‘big data’ is to extract information from these databases to make smarter decisions. We explore the feasibility of this approach for better decision-making for maintenance, specifically for rail infrastructure. We argue that the data should be used within a Bayesian framework with the aim of inferring the underlying state of the system so we can predict future failures and improve decision-making. Within thi...
Bayesian Networks in Project Management Yet, Barbaros (2017-01-01) Bayesian networks (BNs) offer unique benefits for combining data and expert knowledge to model complex joint probability distributions. Recent advances in inference algorithms enabled efficient computation of BNs with both discrete and continuous variables that are also called hybrid BNs. Consequently, BNs have been widely used as risk assessment and decision support tools in various domains including project management. This article illustrates the use of BNs in different aspects of project management and ...
Flexible Content Extraction and Querying for Videos Demir, Utku; KOYUNCU, Murat; Yazıcı, Adnan; Yilmaz, Turgay; SERT, MUSTAFA (2011-10-28) In this study, a multimedia database system which includes a semantic content extractor, a high-dimensional index structure and an intelligent fuzzy object-oriented database component is proposed. The proposed system is realized by following a component-oriented approach. It supports different flexible query capabilities for the requirements of video users, which is the main focus of this paper. The query performance of the system (including automatic semantic content extraction) is tested and analyzed in t...
Extracting Sequential Patterns Based on User Defined Criteria Alkan, Oznur Kirmemis; Karagöz, Pınar (2013-09-13) Sequential pattern extraction is essential in many applications like bioinformatics and consumer behavior analysis. Various frequent sequential pattern mining algorithms have been developed that mine the set of frequent subsequences satisfying a minimum support constraint in a transaction database. In this paper, a hybrid framework to sequential pattern mining problem is proposed which combines clustering together with a novel pattern extraction algorithm that is based on an evaluation function, which utili...
Compatible and incompatible abstractions in Bayesian networks Yet, Barbaros (2014-05-01) The graphical structure of a Bayesian network (BN) makes it a technology well-suited for developing decision support models from a combination of domain knowledge and data. The domain knowledge of experts is used to determine the graphical structure of the BN, corresponding to the relationships and between variables, and data is used for learning the strength of these relationships. However, the available data seldom match the variables in the structure that is elicited from experts, whose models may be qui...
