Opis:
Companies, facing globalization and technological revolution, are constantly forced to search for new ways to grow and develop. A profitable growth strategy can be built through international expansion. Recently it has become one of the few effective ways to develop and enhance the competitiveness of a company in response to the changing dynamics of the global economy. When a company is expanding its business operations to overseas markets a number of strategic decisions must be taken. The company must define the product it wants to market (what), the country market it wants to enter (where), the timing of entry (when) and the entry mode it wants to use (how). Consequently, the country market selection plays a critical role in shaping the performance of foreign activities and influences the future success of the company. This is a complex and difficult decision, requiring the company to analyse a wide spectrum of factors that affect both investment efficiency and effectiveness. The location selection in international expansion may be determined by general macroeconomic factors, demand factors, socio-political factors or cost factors. The purpose of this paper is to conduct a simulation of the market selection decision with the help of multi-criteria decision aiding methods based on the perspective of a dynamically developing company that is a leading manufacturer and distributor of hygiene, cosmetic and medical products.

Opis:
The problem of selecting 3PL (Third Party Logistics) suppliers is a major issue in the management of the supply chain and the improvement of the production management of a manufacturing company. A 3PL supplier can be defined as a company that provides contract logistics services to a manufacturer, supplier or main user of a product or service. It is called a third party because the logistics provider does not own the products but participates in the supply chain between the manufacturer and the user of a given product. In actual cases, several decision-makers intervene in the selection of 3PL suppliers and each one has his own points of view and wishes to take into account criteria which are not generally the same for all the decision-makers. Furthermore, the criteria have different weights. In this study, we propose a method to solve this problem. It consists of a combination of the fuzzy Stepwise Weight Assessment Ratio Analysis (SWARA) method with the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The objective is to optimize the decision-making process and have another, more dynamic model and satisfy the needs of the decision-maker. Fuzzy SWARA is one of the new methods being used for ranking evaluation criteria based on decision makers’ expected degree of importance to determine the weights of evaluation criteria (Selçuk, 2019). This method can be used to facilitate estimation of decision makers’ preferences regarding the meaning of attributes in the weight determination process. TOPSIS is a multi-criteria method for identifying solutions from a finite set of alternatives (Behzadian et al., 2012). To the best of our knowledge, this combination has not been developed in the literature, especially in the third-party logistic problems. The proposed model will be implemented to solve a 3PL problem of a company selling steel products.

Opis:
Decisions regarding agricultural production involve multiple goals. A multicriteria approach allows decision makers to consider more aspects of the decision scenario, although it also leads to other problems, such as difficulties with the selection of goals or criteria, as well as assigning them appropriate weights. It is argued that not only do goals vary depending on the decision-makers’ socioeconomic features, but their relative importance changes as well. A simulation study has been conducted based on the Farm Accountancy Data Network (FADN) database. We use the distance-to-the-negative-solution maximization model. Seven sets of criteria and different sets of weights are considered. The main purpose of the study is to determine the impact of weights on the quality of the model. Quality is assessed by comparing the optimal and observed values of the decision variables. The results lead to the conclusion that the differences between the quality of various models are small.

Opis:
Growing concern about transportation emissions and energy security has persuaded urban professionals and practitioners to pursue non-motorized urban development. They need an assessment tool to measure the association between the built environment and pedestrians’ walking behaviour more accurately. This research has developed a new assessment tool called the Walkable Integrated Neighbourhood Design (WIND) support tool, which interprets the built environment’s qualitative variables and pedestrians’ perceptual qualities in relation to quantifiable variables. The WIND tool captures and forecasts pedestrians’ mind mapping, as well as sequential decision-making during walking, and then analyses the path walkability through a decision-tree-making (DTM) algorithm on both the segment scale and the neighbourhood scale. The WIND tool measures walkability by variables clustered into five features, 11 criteria and 92 subcriteria. The mind-mapping analysis is presented in the form of a ‘Walkability_DTM-Mind-mapping sheet’ for each destination and the overall neighbourhood. The WIND tool is applicable to any neighbourhood cases, although it was applied to the Taman Universiti neighbourhood in Malaysia. The tool’s outputs aid urban designers to imply adaptability between the neighbourhood environment and residents’ perceptions, preferences and needs.

Opis:
Safe, efficient and user-friendly transportation of people and goods have been a premier point of concern for all the developed and the developing countries around the globe. National Highway N-5 or GT road is the most important highway link in Pakistan. It carries about 80% of the country freight traffic. When this heavy traffic passes through the twin cities of Rawalpindi and Islamabad, it causes congestion and environmental hazards particularly in business centers of Rawalpindi city. Because of this heavy traffic volume passing through the cities situated along N-5, bypasses to all of them have been provided however, Rawalpindi is the only city along N5 which is still without a bypass. A bypass to Rawalpindi city is, therefore, inevitable. Besides this, the Bypass will also provide a short access to the traffic on the Motorway (M2) destined for the western part of Rawalpindi. For this research work, Rawalpindi Bypass is taken as a hypothetical scenario and is evaluated for its benefits. Besides addition to the networks of highways across Pakistan, this bypass has many other benefits which include a decrease in congestion from Islamabad and Rawalpindi main arteries (ISB Highway and IJP Road) that results in travel time savings, vehicle operating cost savings, safety savings, and reduced air pollution. This research aims to produce an engineering and scientific comparison of various costs and benefits associated with the road agency and users about the construction of an alternative. The Project involves transportation demand estimation on different segments of the National and Arterial roads, Project Costs, travel time savings, safety saving, vehicle operating cost savings, economic efficiency analysis, Air quality impact and multi criterion transportation decision making. The transportation decision making process usually involves the evaluation of effectiveness and efficiency of an alternative decision with respect to a base case DO-NOTHING Scenario. The authors have taken the existing roadway structure with no improvements as DO-NOTHING Scenario, whereas the construction of Rawalpindi Bypass (60 km) with 2 lanes in each direction is taken as Alternative B and Rawalpindi Bypass (51 km) as Alternative C. Multi criteria decision making technique is used for decision because of multiple options with different dimensions, both monetary and non-monetary. Basing of MCDM this study recommends Alternative C (51 km) for Rawalpindi Bypass.

Przy podjęciu ostatecznej decyzji pomocne jest zastosowanie metod wielokryterialnego wspomagania decyzji (WWD). Metody te coraz częściej stosowane są do rozwiązywania problemów transportu publicznego. W artykule przedstawiono ogólną ideę wielokryterialnego podejmowania decyzji, klasyfikację metod WWD, a następnie zastosowanie metod szeregowania wariantów w problemach transportu publicznego. Na podstawie tabelarycznego zestawienia metod i problemów w których zostały one zastosowane można zaobserwować, które z nich są najczęściej stosowane w tego typu zagadnieniach.
When we are planning the route of public transport vehicles or purchasing means of public transport many times we wonder which solution which option will be best for all stakeholders. During the final decision making, is helpful to use methods of multi-criteria decision making (MCDM). These methods are increasingly being used to solve problems of public transport. This article presents a general idea of multi-criteria decision-making methods of classification of MCDM, and then use methods of ordering variants in the problems of public transport. On the basis of the tabular statement of the methods and problems in which they were applied, you can see which ones are most often used in these types of issues.

Sorting problematic
Opis:
Crisp values are insufficient to model real-life situations and imprecise ideas are frequently represented in multicriteria decision aid analysis. In fact, it is difficult to treat the evaluation criteria precisely and to fix exact preferences rating. The triangular intuitionistic fuzzy numbers succeeded to treat this kind of ambiguity in a great deal of research than other forms of fuzzy representation functions. The field of sorting issues is an active research topic in the multiple criteria decision aid (MCDA). This study extended one of the sorting methods, FLOWSORT, for solving multiple criteria group decision-making problems. This extension described the preferences rating of alternatives as linguistic terms which can be easily expressed in triangular intuitionistic fuzzy numbers. To validate our extension, an illustrative example as well as an empirical comparison with other multi-criteria decision making methods is presented.

The aim of the paper is to present the practical use of a combination involving two multicriteria methods: AHP (analytic hierarchy process) and TOPIS (The Technique for Order of Preference by Similarity to Ideal Solution), in order to expertly assess the level of sustainable development of counties in the West Pomeranian Province in 2010 and 2017. The article was divided into two main parts. The theoretical (methodological) part contains the characteristics of AHP and TOPSIS methods; in turn, the results of the analysis were presented in the empirical part. The main source of statistical data is the annual report published by Statistical Office in West Pomeranian Province, which contains the information on most important development areas (e.g. population, ecology, pollution, health, employment, macroeconomics, transport, tourism, agriculture, etc.). In other words, the purpose of the article is to build a synthetic measure of sustainable development, which will take into account socio-economic determinants for deliberately selected entities from a regional perspective. This approach will allow a detailed analysis of sustainable development according to the adopted criteria for 2010 and 2017, and may be the basis for further investigations in order to look for more complex dependencies among the factors which determine sustainable development of the studied phenomena and objects.

A multi-criteria model for determining the order size for materials used in production has been presented. It was assumed that the consumption rate of each material is a random variable with a known probability distribution. Using such a model, in which the purchase cost of materials ordered is limited, three criteria were considered: order size, probability of a lack of materials in the production process, and deviations in the order size from the consumption rate in past periods. Based on an example, it has been shown how to use the model to determine the order sizes for polyurethane adhesive and wood in a hard-coal mine.

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.

Opis:
In the paper an approach to decision making in situations with non-pointlike characterisation and subjective evaluation of the actions is considered. The decision situation is represented mathematically as fuzzy multiobjective linear programming (fMOLP) model, where we apply the reduced fuzzy matrices instead of fuzzy classical numbers. The fMOLP model with reduced parameters is decomposable into the set of point-like models and the point-like models enable effective construction of an optimisation procedure - fBIP, see Wojewnik (2006ab), extending the bireference procedure by Michalowski and Szapiro (1992). The approach is applied to a fuzzy optimization problem in the area of telecommunication services.

Opis:
The reference point method (RPM) is based on the so-called augmented max-min aggregation where the worst individual achievement maximization process is additionally regularized with the average achievement. In order to avoid inconsistencies caused by the regularization, we replace it with the ordered weighted average (OWA) which combines all the individual achievements allocating the largest weight to the worst achievement, the second largest weight to the second worst achievement, and so on. Further following the concept of the weighted OWA (WOWA) we incorporate the importance weighting of several achievements into the RPM. Such a WOWA RPM approach uses importance weights to affect achievement importance by rescaling accordingly its measure within the distribution of achievements rather than by straightforward rescaling of achievement values. The recent progress in optimization methods for ordered averages allows us to implement the WOWA RPM quite effectively as extension of the original constraints and criteria with simple linear inequalities.

A concern about the current state of relations between industry and the environment is often neglected. However, it is important to underline that industry and sustainability are not mutually exclusive. There are many industrial processes to blame when analyzing the negative impact on current socio-ecological environment. The emerging question is whether companies nowadays are ready to face challenges in the name of sustainability, the future of the planet and generations to come. In addition, an assessment of industrial processes may be very time-consuming and costly in financial terms. This fact allows developing sustainability assessment approach and its measures for keeping track on to evaluate scale of environmental, social and economic changes. The goal of the paper is to develop a multicriteria decision-making approach for sustainability assessment of renewable energy technology. A sustainability assessment approach combines life cycle-based methods integrated with multi-criteria decision-making method based on analytical hierarchy process. The resulting assessment method allows finding a compromise between industry and the environment and identify potential intervention points for further research. As a result of decision-making process, string ribbon technology was considered as the most sustainable. The applicability of the proposed method is assessed based on photovoltaic panels.

Opis:
Currently, an important issue in multi-criteria decision-making (MCDM) problems are vagueness and lack of precision of decision-making information because of insufficient data and incapability of the decision maker to process the information. Intuitionistic fuzzy sets (IFS) are a solution to eliminate the vagueness and the uncertainty. While fuzzy sets (FS) deal with ambiguity and vagueness problem, IFSs have more advantages. Moreover, the CODAS-SORT method cannot handle the uncertainty and ambiguity of information provided by human judgments. The aim of this study is to develop an IF extension of CODAS-SORT combining this method with the IFS theory. To achieve this, we use the fuzzy weighted Euclidean distance and fuzzy weighted Hamming distance instead of the crisp distances. A case study of a supplier selection assessment is used to clarify the details of our proposed method.

Opis:
The Analytical Hierarchy Process (AHP) is one of the multi-criteria methods with tools that are effective for decision-making in complementary or alternative medicine (CAM). This approach, in combination with other available methods, such as the Utrecht Method, allows medical professionals and patients themselves to take a balanced choice of special treatment and health control. This is particularly important for pregnant women who suffer from nausea and vomiting during pregnancy (NVP). The mechanisms of toxicosis occur, and the way of treatment have certain uncertainties. The decision-making process for therapeutic care must consider several factors, the determination of which is the result of collaboration between the patient and the healthcare provider. This paper presents the results of a decision-making study regarding the use of the ginger medicinal plant in helping a woman with NVP symptoms. The research was conducted using the original questionnaire according to the methodology proposed by the developers of the Utrecht Method. The chosen respondents were healthcare professionals with experience in treating NVP and pregnant women. The Analytical Hierarchy Process (AHP) capabilities in decisionmaking were shown in an example of analyzing the benefits, risks, and side effects of using ginger during pregnancy. The combination of two methodological approaches allowed to successfully connect the proven facts of using CAM therapy with the subjective assessment of all stakeholders. The study demonstrates that this approach successfully uses decision-making by structuring hierarchical decision elements and weighing the criteria involved in the decision-making issue. The article examines the practicality and effectiveness of using AHP when making decisions regarding the treatment and improvement of the condition of pregnant women with NVP, and summarizes the quantitative and qualitative indicators of the effectiveness of this method. The presented combination of two methodological approaches in decision-making allows for choosing an optimized medical strategy for supporting pregnant women through CAM therapy.

Opis:
The paper relates to the trading systems supporting traders ma- king decision on the forex market. Typical trading systems using tech- nical analysis generate a buy or sell signal when the technical indicator crosses a given oversell or overbought levels. The paper extends the approach in which the above strict crisp conditions are replaced by fuzzy relations. The indicators are treated not independently as it is in the typical systems but jointly. Currency pairs are compared in the muliticriteria space in which each criterion is dened by a membership function referring to a given indicator. New formulations of the mem- bership functions for dierent indicators are proposed. General ideas of the algorithm generating non-dominated alternatives in the multi- criteria space are presented. The algorithm has been implemented in an experimental system. Computational results for dierent time win- dows using real-world data from the forex market are presented and discussed.

Opis:
Intelligent decision system (IDS) is a window-based software package that has been developed on the basis of the evidential reasoning (ER) approach, a recent development in handling hybrid multiple criteria decision analysis (MCDA) problems with uncertainties. In this paper, the evidential reasoning approach will be briefly described first, and its major differences from and the relationships with conventional MCDA methods will also be discussed. Then the main features, advantages and benefits of IDS will be demonstrated and explained using two application examples: supplier pre-qualification assessment and customer satisfaction survey analysis, which have been investigated as part of the research projects led by the authors and funded by the UK government and the EC. It is concluded in the paper that the ER approach can be used not only to deal with problems that traditional methods can solve, but also to model and analyse more complicated decision problems that traditional methods are incapable of handling.

Opis:
W pracy opisano propozycję nowego podejścia, które można wykorzystać w wielokryterialnym podejmowaniu decyzji w przypadku poszukiwania optymalnej strategii czystej w warunkach niepewności (decydent nie zna bądź nie zamierza skorzystać z informacji o prawdopodobieństwie wystąpienia poszczególnych stanów natury). Prezentowana reguła decyzyjna poprzedzona jest etapem prognostycznym, w ramach którego brane jest pod uwagę nastawienie decydenta do ryzyka (rozumianego jako możliwość uzyskania niekorzystnej wypłaty) mierzone współczynnikiem optymizmu. Etap ten służy do wyłonienia najbardziej „prawdopodobnego” (tj. odzwierciedlającego naturę decydenta) scenariusza bądź zbioru najbardziej „prawdopodobnych” scenariuszy i ma na celu zawężenie pierwotnej macierzy wypłat, na podstawie której wybierana jest najlepsza decyzja. Procedura odwołuje się do planowania scenariuszowego i do metody SF+AS (ang. Scenario Forecasting + Alternative Selection Method) przedstawionej w innym artykule i znajdującej zastosowanie w jednokryterialnych problemach decyzyjnych.
The author describes a new approach which may be used in uncertain multicriteria decision making with scenario planning to searching an optimal pure strategy. The decision maker does not know the likelihood of particular scenarios. The decision rule is supported by a forecasting stage within which scenarios reflecting the decision maker’s attitude towards risk (understood as a possibility that some bad circumstances might happen) are selected. The nature of the decision maker is measured by the coefficient of optimism. Hence, the final strategy is chosen on the basis of a reduced aggregated payoff matrix. The procedure refers to SAW (Simple Additive Weighting Method) and to SF+AS method (Scenario Forecasting + Alternative Selection Method), presented in an other paper and devoted to one-criterion decision problems.

Opis:
The paper has 3 objectives: (i) identify QoL determinants of Russian Students; (ii) assess their relevance for decision-making when choosing life strategies; (iii) recognize their implications for academic teaching. The research sample were students from two Russian Universities. The study employed: literature analysis;exploratory research (direct individual in-depth interviews, survey based on a self-administered, web-based questionnaire with single-answer, limited choice qualitative & quantitative questions and gradings based on the Likert-type scale); explanatory research (informal moderated group discussions). The research findings show the relatively high significance of finance, career,stability, family, free time and other non-material QoL determinants. Research analysis reveals an inconsistency between respondents’ expectationsand their work-life balance, which imposes a question about decision-makingcriteria at an early stage of career planning and the role of tertiary educationin this process. Implications & Recommendations: (i) multicriteri decision-making processes, such as career planning, should comprise worklife balance; therefore both material and non-material QoL determinants should be incorporated into the analysis; (ii) as the role of Universities, beside educating, is also to guide and shape characters, Academia seems to be the right place for this task; (iii) therefore Universities should promote conscious lecturers as assistants to the process of identification of individual QoL determinants by their students. Contribution & Value Added: the research provides a fresh and improved perspective on quality of life and its determinants; it includes non-material QoL components and therefore brings qualitative determinants into economic research; it will provide data future comparisons; it comes from a research network linking European and Russian tertiary education institutions and University lecturers with intercultural teaching experience.
