Opis:: This paper considers a four-dimensional multi-objective multi-item transportation problem (4DMOMITP), where all the parameters are regarded as uncertain variables. In this paper, three mathematical models, namely expected value model (EVM), optimistic value model (OVM) and dependent optimistic-constrained model (DOCM), are discussed for the uncertain model of 4DMOMITP. These models are converted into their corresponding deterministic forms using different ranking criteria from uncertainty theory. These deterministic models are then solved by using the Lingo 18.0 software, utilizing three different classical approaches for obtaining a solution. A numerical example is given to illustrate the application of the model and the solution algorithm. A sensitivity analysis for the OVM and DOCM models has also been performed with respect to the confidence levels.

Tematy:: non-linear solid transportation problem
impurity constraints
fuzzy programming technique
Opis:: An innovative, real-life solid transportation problem is explained in a non-linear form. As in real life, the total transportation cost depends on the procurement process or type of the items and the distance of transportation. Besides, an impurity constraint is considered here. The proposed model is formed with fuzzy imprecise nature. Such an interesting model is optimised through two different fuzzy programming techniques and fractional programming methods, using LINGO-14.0 tools followed by the generalized gradient method. Finally, the model is discussed concerning these two different methods.

Opis:: We have proposed Fuzzy-CBR to find a solution from past knowledge retrieved from the database and adapted to the new situation. However, ontology is needed in identifying concepts, relations and instances that are involved in a situation in order to improve and facilitate the efficient retrieval of similar cases from the CBR database. This paper proposes the way to apply ontology for identifying the concepts involved in a new case, used as inputs, for ship collision avoidance support system and in solving for similarity through document articulation and abstraction levels. These ontologies will be used to build a conceptual model of a manoeuvring situation.

Opis:: The current study aims at identifying and ranking the creativity and innovation techniques in automotive industry of Iran. Considering the purpose of the research, the current study is practical and in terms of method it is a descriptive-survey one. Data were collected using a questionnaire, and to confirm its validity and reliability, content analysis and Cronbach’s alpha coefficient were used, respectively. Fuzzy TOPSIS technique was used to analyze data. The results of the study show that fishbone diagram has been identified as the most important creativity technique in Iran’s automotive industry and creative mutation, nominal group, Delphi, creative visualization and returning to the customer techniques stand in the next ranks.
Celem badania jest zidentyfikowanie oraz stworzenie rankingu technik kreatywności i innowacji w branży motoryzacyjnej Iranu. Biorąc pod uwagę cel badania, ma ono charakter praktyczny, a zastosowana metoda to metoda opisowo-sondażowa. Dane zostały zebrane przy użyciu kwestionariusza, a w celu potwierdzenia ich trafności i rzetelności, zostały wykorzystane odpowiednio: analiza treści oraz współczynnik alfa Cronbacha. Rozmyta metoda TOPSIS została wykorzystana w celu analizy danych. Rezultaty badania wskazują, że diagram rybiej ości został zidentyfikowany jako najistotniejsza technika w branży motoryzacyjnej Iranu. Na kolejnych pozycjach znalazły się następujące techniki: kreatywna mutacja, grupa nominalna, Delphi, kreatywna wizualizacja i powracanie do klienta.

Tytuł:: Evaluating organizational antifragility via fuzzy logic : the case of an Iranian company producing banknotes and security paper

Opis:: The concept of antifragility has received much attention from researchers in recent years. Contrary to fragile systems which fail when exposed to stressors, antifragile systems prosper and improve in response to unpredictability, volatility, randomness, chaos and disturbance. The implications of antifragility goes beyond resilience or robustness. A resilient system resists stress and remains the same; while an antifragile system improves. Taleb argues that antifragility is required for dealing with events that he called black swans or X-events, which are scarce, unpredictable, and extreme events. Such events come as a surprise and have major consequences. The concept of antifragility was developed by Taleb in a socioeconomic context, not in industrial production. However, the authors think that this concept may have its greatest practical utilization when applied to industrial environments. Thus, they focused on this concept in the article aiming to investigate the level of antifragility in an organization. In order to perform this, the authors used a case study based on an Iranian manufacturer of banknotes and security paper (TAKAB). Firstly, a questionnaire was designed based on 7 criteria related to antifragility using the five-point Likert scale and a triangular fuzzy number for each linguistic term is defined. In the next phase, the weight of each component was obtained using the entropy technique. In the final stage, the Euclidean distance between the aggregated fuzzy antifragility index (FAI) and each linguistic term used during this case study was calculated. Finally, based on these results, the level of the organization’s antifragility was assessed as satisfactorily antifragile, based on the minimum Euclidean distance.
