    Opis:
    In most of multicriteria aggregation methods, we need to elicit parameters that are generally determined directly by the decision-maker (DM). Direct assigning of parameters and criteria weights presents a crucial and difficult step in the decision-making process. However, this kind of information is too subjective and may affects the reliability of the results. To overcome this issue, we suggest a weighting method based on mathematical programming to incorporate the DM’s preferences indirectly within the ARAS method.

    Opis:
    Today, the changes in market requirements and the technological advancements are influencing the product development process. Customers demand a product of high quality and fast delivery at a low price, while simultaneously expecting that the product meet their individual needs and requirements. For companies characterized by a highly customized production, it is essential to reduce the trial-and-errors cycles to design new products and process. In such situation most of the company’s knowledge relies on the lessons learnt by operators in years of work experience, and their ability to reuse this knowledge to face new problems. In order to develop unique product and complex processes in short time, it is mandatory to reuse the acquired information in the most efficient way. Several commercial software applications are already available for product lifecycle management (PLM) and manufacturing execution system (MES). However, these two applications are scarcely integrated, thus preventing an efficient and pervasive collection of data and the consequent creation of useful information. The aim of this paper is to develop a framework able to structure and relate information from design and execution of processes, especially the ones related to anomalies and critical situations occurring at the shop floor, in order to reduce the time for finalizing a new product. The framework has been developed by exploiting open source systems, such as ARAS PLM and PostgreSQL. A case study has been developed for a car prototyping company to illustrate the potentiality of the proposed solution.

    Opis:
    Research background: The critical role of online games in e-commerce and the great competition among providers to enhance market share has significantly increased the need to use effective advertising patterns, techniques, and tools to attract users. There are two significant challenges to planning online media game selection. The first challenge is that there is no agreement on media selection criteria for online game advertising. The second challenge relates to the complexity of choosing advertising media. Purpose of the article: Given the multidimensionality and uncertainty in evaluating and selecting advertising media, especially in the case of online games, the need to provide a systematic framework for evaluating and selecting media is critical. Methods: The present study aims to provide a systematic framework based on multi-attribute decision-making (MADM) methods to evaluate and select the appropriate media for online game advertising. For this purpose, first, by reviewing the literature, a relatively comprehensive list of media selection criteria for online game advertising was extracted and then provided to experts in online game marketing and advertising in the fuzzy Delphi questionnaire. Then, based on their opinions, a localized decision model was obtained. Also, the Step-wise Weight Assessment Ratio Analysis (SWARA) method helped to determine the criteria' importance. In the next step, a preliminary list of online game advertising media was prepared and evaluated by experts based on the criteria obtained in the previous step. Finally, the media was ranked using the Additive Ratio ASsessment (ARAS) method. Findings & value added: Awareness of the criteria affecting the selection of online game advertising media and having a systematic framework for applying these criteria in advertising media selection decisions play a vital role in practical decisions. This research addresses one of the main gaps in the field of study by proposing a quantitative methodology for integrating information based on the knowledge of experts in the decision-making processes select advertising media for online games. Most traditional media selection processes are based solely on experience and estimation, and in practice, they are unable to systematically prioritize the alternatives due to the multiplicity of media available and the complexity of the decision-making process Interval-valued triangular fuzzy numbers (IVTFNs) can address the shortcomings of previous research while considering the uncertainties in this decision-making process. The findings of this framework can be good support for e-commerce managers and online game advertising practitioners.

    Opis:
    Criteria weight inference is a crucial step for most of multi-criteria methods. However, criteria weights are often determined directly by the decision-maker (DM) which makes the results unreliable. Therefore, to overcome the imprecise weighting, we suggest the use of the preference programming technique. Instead of obtaining criteria weights directly from the DM, we infer them in a more objective manner to avoid the subjectivity and the unreliability of the results. Our aim is to elicit the ARAS-H criteria weights at each level of the hierarchy tree via mathematical programming, taking into account the DM’s preferences. To put it differently, starting from preference information provided by the DM, we proceed to model our constraints. The ARAS-H method is an extension of the classical ARAS method for the case of hierarchically structured criteria. We adopt a bottom-up approach in order to elicit ARAS-H criteria weights, that is, we start by determining the elementary criteria weights (i.e. the criteria at the lowest level of the hierarchy tree). The solution of the linear programs is obtained using LINGO software. The main contribution of our criteria weight elicitation procedure is in overcoming imprecise weighting without excluding the DM from the decision making process.

    The reconstruction the heroic cycle of Ǝrəxša is one of the main targets of our investigations. The present cycle cannot be studied just as an isolated fragment of an archaic epos, but that it must be framed into a larger theme, that of the bow and the arrow, which among the Indo-European tribes of the East, mostly Indo-Iranians and Hittites, assumed a remarkable importance.

    Opis:
    Celem artykułu jest zwrócenie uwagi na materiały, które składają się z naturalnych substratów, takich jak: SiO₂, CaO, H₂O, a następnie na termiczne i wilgotnościowe dysponowanie materiałem, szczególnie w aspekcie rozwoju szkodliwych mikroorganizmów w materiałach budowlanych. Autoklawizowane wyroby silikatowe odznaczają się zasadowym odczynem, który nie sprzyja rozwojowi grzybów, pleśni czy innych szkodliwych mikroorganizmów, natomiast ich mikrostruktura zbudowana jest z uwodnionych krzemianów wapniowych typu tobermoryt o stosunku CaO/SiO₂ = 0,83 i fazy C-S-H. Korzystnymi właściwościami tego rodzaju produktów budowlanych są: nasiąkliwość, która wynosi 16%, i dodatkowo wysoka wytrzymałość na ściskanie o wartości minimum 13 MPa. W artykule zaproponowano wykorzystanie metody ASR (ang. Additive Ratio Assessment - ARAS) do opracowania modelu i analizy użytych materiałów budowlanych, które mają wpływ na mikroklimat w pomieszczeniu. Studium przypadku można zdefiniować jako problem decyzyjny.
    The construction industry in a special way affects the condition of the state of the environment and human. It is necessary to search for materials with the lowest degree of risk to humans. The aim of the article is to focus attention on the materials which are composed of natural components such as: SiO₂, CaO, H₂O, and next on the thermal and moisture management of the material in the aspect of development of harmful microorganisms in construction materials (including the modified ones). The microstructure of the materials usually includes tobermorite with a ratio CaO/SiO₂ = 0.83 and C-S-H phase, impregnability 16%, and compressive strength minimum 13 MPa. The article proposes the use of the ASR (Additive Ratio Assessment-ARAS) method to develop a model and analysis of the used building materials that affect the microclimate in the room. A case study can be defined as a decision problem.
