Opis:: This study provides a systematic review of the existing academic literature describing the key components of eMaintenance. The current literature is reviewed by utilizing a number of academic databases including Scopus, SpringerLink and ScienceDirect, and Google Search is used to find relevant academic and peer-reviewed journal articles concerning eMaintenance. The literature describes eMaintenance as an advanced maintenance strategy that takes advantage of the Internet, information and communication technologies, wireless technologies and cloud computing. eMaintenance systems are used to provide real time analyses based on real time data to offer a number of solutions and to define maintenance tasks. The collection and analysis of appropriate maintenance and process data are critical to create robust ‘maintenance intelligence’ and finally improvements in manufacturing costs, safety, environmental impact, and equipment reliability. This paper describes how the scientific discussion on eMaintenance has expanded significantly during the last decade, creating a need for an up-to-date review. As a conclusion, three research gaps in the area of eMaintenance are identified, including evaluating the benefits of eMaintenance, agreeing on a comprehensive definition, and developing tools and structures for cooperative eMaintenance.

Opis:: A calculation model of teaching costs in a university is a system of guidelines, notions and relations to facilitate an assessment of the costs generated by individual university departments, majors, subjects etc. The existing calculation models based on the assessment of costs with the use of precision data prove to be ineffective in practice. The major drawback of these systems is the fact that it is not possible to take into account non-precision data in relation to cost generating factors (e.g. the number of didactic groups, hourly rates etc.). This article presents the author’s own proposal of a cost calculation model based on the formalism of fuzzy logics (with the use of the L-R representation). On the basis of the model proposed, it is possible to assess the costs of an academic subject with imprecise information concerning cost generating factors, or the values of those factors are assessed which imply the values set of the cost of a subject.

Opis:: During the previous two decades liner carriers within maritime shipping have broken the barriers from being pure transportation providers towards being logistics service providers. Most of the top 20 liner carriers worldwide hale set up spin-offs providing services from local booking up to 3rd party logistics services, combining the business advantages of tight linkages with liners together with the negotiation freedom with demanding customers by providing an extension of service coverage. Economical evaluations of transocean routes and global networks are of interest for decision makers responsible for business strategies as well as for operations. It is crucial to achieve appropriate judgements about which liner routes are profitable and how to build better service networks so that the companies' brand could be attractive to, e.g., ship- pers, including exporters, importers and forwarding agents. In this paper we discuss the corresponding trade-offs as well as related decision support systems of relevant service providers and companies.

Opis:: This article presents the problem of consensus determining postulates defined in decision support systems. The consensus determining methods and the general postulates for consensus estimation and their characteristics are presented in the first part. Next, the definitions of new postulates pertaining to decisions support systems were elaborated, and the possibility of their use in practical solutions is presented. The consensus function granting these postulates is also characterized. The application of these postulates, as a consequence, can lead to the process of making decisions will be more flexible, and the risk involved in decisions will be significantly reduced.

Opis:: Cloud computing presents scientists and engineers with new challenges related to the architecture of information systems and their use. This paper addresses the problem of deployment of decision supporting system in computing cloud. The author of the document presented the application of this approach that lies on intelligent discovery of web services within geographic information systems. Many important aspects of nowadays’ IT systems have been considered like the domain of Web GIS, network of agents architecture, semantics and ontology, integration of external knowledge bases, deployment of applications into the cloud. It has been proven that based on them, it is possible to create a software that uses a natural language to submit queries to a system whose operating environment is a PaaS (Platform as a Service) class platform. Another aspect discussed in this article was the approach to build so-called virtual organizations in which data and knowledge exchange takes place via web services. As an example, integration with Google Geocoding API is shown, where the web API provides geographic location based on the location expressed in natural language, e.g. home address, tourist point.

Opis:: W trakcie podejmowania decyzji często istnieje konieczność wykorzystania informacji, które są niepewne lub niekompletne. Wśród wielu narzędzi formalnych wspomagających proces podejmowania decyzji godne uwagi wydają się sieci bayesowskie (przekonaniowe). Ich nazwa pochodzi od zajmującego ważne miejsce w rachunku prawdopodobieństwa i statystyce twierdzenia Bayesa, które postuluje rewizję wcześniejszych przekonań w świetle nowych faktów. Wiedza dziedzinowa jest tu zakodowana w postaci grafu, którego topologia naśladuje przyczynową strukturę dziedziny.
When decision making there is often a need to use information that is uncertain or incomplete. Among many formal tools for supporting decision-making process Bayesian networks (belief) seem to be noteworthy. The name origins from Bayes' theorem, occupying an important place in probability and statistics, which postulates a revision of the earlier beliefs in the light of new facts. The knowledge is here encoded in the form of a graph, which mimics the topology of the causal structure of the domain.

Opis:: Multi-criteria decision-making (MCDM) methods are associated with the ranking of alternatives based on expert judgments made using a number of criteria. In the MCDM field, the distance-based approach is one popular method for receiving a final ranking. One of the newest MCDM method, which uses the distance-based approach, is the Characteristic Objects Method (COMET). In this method, the preferences of each alternative are obtained on the basis of the distance from the nearest characteristic objects and their values. For this purpose, the domain and fuzzy numbers set for all the considered criteria are determined. The characteristic objects are obtained as the combination of the crisp values of all the fuzzy numbers. The preference values of all the characteristic object are determined based on the tournament method and the principle of indifference. Finally, the fuzzy model is constructed and is used to calculate preference values of the alternatives. In this way, a multi-criteria model is created and it is free of rank reversal phenomenon. In this approach, the matrix of expert judgment is necessary to create. For this purpose, an expert has to compare all the characteristic objects with each other. The number of necessary comparisons depends squarely to the number of objects. This study proposes the improvement of the COMET method by using the transitivity of pairwise comparisons. Three numerical examples are used to illustrate the efficiency of the proposed improvement with respect to results from the original approach. The proposed improvement reduces significantly the number of necessary comparisons to create the matrix of expert judgment.

Opis:: There are advantages in considering the routing problem in integrated communication networks as a multiobjective shortest path problem, having in mind to grasp eventual conflicts and trade-offs among distinct objectives and quality of services (QoS) constraints. On the other hand the utilisation of dynamic routing methods in various types of networks is well known to have significant impact on network performance and cost, namely in overload and failure conditions. This paper presents the detailed formulation of a proposal of a multiple objective dynamic routing method (MODR) of periodic state dependent routing type, enabling to represent distinct QoS related metrics and requirements in a consistent manner. The MODR method present formulation is based on a multiple objective shortest path model with constraints and is prepared to use implied costs as one of the metrics. Alternative paths tor each traffic flow are changed as a function of periodic updates of certain QoS related parameters estimated from real time measurements on the routes and trunks of the network. Such paths are computed by a specialised and efficient variant of a bi-objective shortest path constrained algorithm, developed for the MODR, enabling to incorporate flexible requirements on the QoS metrics. The architecture of the routing system is discussed together with the features of its main modules. An illustrative example of application of the MODR path calculation module to a circuit-switched type network using blocking probability and implied cost as metrics, is also presented, considering different overload conditions.
