Opis:
Scheduling of multiobjective problems has gained the interest of the researchers. Past many decades, various classical techniques have been developed to address the multiobjective problems, but evolutionary optimizations such as genetic algorithm, particle swarm, tabu search method and many more are being successfully used. Researchers have reported that hybrid of these algorithms has increased the efficiency and effectiveness of the solution. Genetic algorithms in conjunction with Pareto optimization are used to find the best solution for bi-criteria objectives. Numbers of applications involve many objective functions, and application of the Pareto front method may have a large number of potential solutions. Selecting a feasible solution from such a large set is difficult to arrive the right solution for the decision maker. In this paper Pareto front ranking method is proposed to select the best parents for producing offspring’s necessary to generate the new populations sets in genetic algorithms. The bi-criteria objectives minimizing the machine idleness and penalty cost for scheduling process is solved using genetic algorithm based Pareto front ranking method. The algorithm is coded in Matlab, and simulations were carried out for the crossover probability of 0.6, 0.7, 0.8, and 0.9. The results obtained from the simulations are encouraging and consistent for a crossover probability of 0.6.

Opis:
The paper is to present a multi-criteria approach for sustainability assessment of manufacturing processes, which can be applied to carry out the sustainability assessment of manufacturing processes requiring less detailed data, time, and expert knowledge, but still providing a company-level analysis. The analytical hierarchy process method is used to determine ranking of simple and relevant activity areas for manufacturing processes in terms of sustainability objectives. Analytical technique is also employed to assess the degree of sustainability in manufacturing due to limited information which appear to be a characteristic of the case study presented. One goal of sustainability characterization methodology is to improve the manufacturing sustainability performance. Similar to the baseline scenario, sustainability reevaluation for sustainability improvement is also applied and discuses performance profile at the process level. This approach seems particularly useful when comparing different processes. It makes applicable for various industries and might be a challenge to derive priorities for systematic improvement. The applicability and usability of the proposed assessment method was verified by the case study in company producing heating devices.

Opis:
The aim of this study is to determine the optimum location for an oil spill response center in the Marmara Sea. The analytic hierarchy process (AHP) and technique for the order of preference by similarity to ideal solution (TOPSIS) method as the most preferred multi-criteria decision-making (MCDM) technique were used. The results reveal that the LOC criterion and PRA sub-criterion have the highest effects on the optimal location selection of the oil spill response center. According to the results, the most suitable location for the oil spill response center in the region is Izmit Bay Entrance. This location has been proposed for the response headquarters to manage the whole operation with the assistance of auxiliary installations in the area. In this study, only technical and operational variables are taken into account, but political and administrative criteria are excluded.

Opis:
Management processes in an organization involve decision-making based on many criteria (MCDM), and in this process ranking of variables plays a vital role. This paper presents the analysis of key business issues of an Indian automotive organization using an efficient interpretive ranking (eIRP) approach. This paper integrates the Situation-Actor-Process (SAP) and Learning-Action-Performance (LAP) framework of the organization with eIRP. It evaluates the ranking of actions to be carried out in an organization with respect to performance parameters. The study highlights the area where the organization should focus on achieving desired business excellence. From the analysis, it is revealed that the top-ranked suggested action for the organization is the adoption of energy policy as a core business policy followed by technology management, maintenance management, and the use of information technology for cost management. This case study is one of the few that uses the SAP-LAP framework for ranking the actors and actions of the organization using the eIRP approach, to make MCDM an easy task.

Opis:
The influence that general contractors and subcontractors have on the operation of a company is immense. Keeping this in mind, the authors have decided to develop and algorithm based on the analysis of partnering relations between construction companies that would select the best possible construction company for the purposes of cooperation. This algorithm, developed for a given construction company, is meant to support its decision-making system in the field of the selection of another construction company to cooperate with. The author has made references to earlier research, in which she had used the ELECTRE III method, and in which she bad analysed the possibility of applying the BIPOLAR method in order to solve the problem of the selection of a construction company to develop partnering relations with. The author provided an example of the calculations performed for a selection of construction companies.
Partnerstwo w odróżnieniu od konkurencji charakteryzuje się współpracą a nie rywalizacją. Partnerzy współpracują, dążąc do realizacji przedsięwzięcia budowlanego, które jest ich wspólnym celem, oraz do osiągnięcia obopólnych korzyści. Istotny wpływ na działalność przedsiębiorstwa budowlanego mają podwykonawcy i generalni wykonawcy. Z tego względu zdecydowano się na opracowanie algorytmu wybierającego najlepsze przedsiębiorstwo budowlane do współpracy podczas realizacji przedsięwzięć budowlanych. Ten algorytm, dla danego przedsiębiorstwa budowlanego, ma wspomagać jego system decyzyjny w zakresie wyboru innego przedsiębiorstwa budowlanego do współpracy partnerskiej. Autorka opracowała i przedstawiła w publikacjach model badawczy relacji partnerskich oraz opracowany algorytm wyboru przedsiębiorstwa budowlanego do współpracy partnerskiej z wykorzystaniem metody ELECTRE III. Wykonała przykład obliczeniowy dla wybranych przedsiębiorstw budowlanych [20]. Na podstawie rankingu zbiorczego metody ELECTRE III wskazała jako najlepsze do współpracy partnerskiej, spośród siedmiu analizowanych, przedsiębiorstwo numer 3 a następnie 7.

Opis:
The problem of choosing the way to move people is often encountered both in scientific research and in everyday life. The difficulty of this process depends on the availability of many variants and the pursuit of satisfying transport needs at the minimum cost, in the shortest possible time and in the most comfortable conditions. The publication presents a decision problem of choosing the best transport option using multi-criteria methods. At the beginning authors presented the widely used methods of solving decision problems in the literature. Subsequently, based on the example of the Warsaw-Wroclaw connection, the MAJA multi-criteria assessment method algorithm was analysed. Both road, rail and air transport options were considered. Six possible variants of solutions were indicated, which were assessed in three sub-criteria: cost, time and comfort of travel. Then, the results of the analysis were compared with the results obtained using other multi-criteria decision-making support methods, i.e. ELECTRE I, AHP, TOPSIS, PROMETHEE, SAW, PVM. The considered methods were divided according to the way the result was presented, as a result of which the methods based on the relation of superiority (which included the MAJA method) and methods using ranking were distinguished, and then an intra-group comparison was made. On the basis of the constructed compliance matrix of the relation of superiority, it was found that domination methods exhibited convergence of the obtained results. However, in order to compare the convergence of the results of the ranking methods, the Spearman's linear correlation coefficient was used. The applied MAJA multi-criteria method has made it possible to determine non-dominated solutions considered optimal taking into account the adopted weights of criteria and compliance and non-compliance thresholds. Its unquestionable advantage is the possibility of using many partial criteria expressed in different measurement units. In the presented example, the best options were the premium express rail transport and airplane. The summary defines the direction of further research and possibilities of modification of the presented method.

Opis:
Planning a construction project, the investor frequently faces the choice of the option of the planned investment. Assessment of options is difficult due to the complex nature of construction projects. Various methods of multicriteria evaluation are successfully applied in the assessment and analysis of options. For those methods to work, a handful of information must be prepared beforehand. Among others, it is necessary to establish the assessment criteria and determine their weight for specific cases. This stage is implemented in cooperation with experts. The results of evaluations, obtained on the basis of the experts' opinions, must be processed and prepared. The paper will discuss one possible option for assessing the experts' opinion.
Wspomaganie decyzji wielokryterialnych wymaga udziału wielu ekspertów wyrażających swoje opinie na badany temat. W celu uzyskania obiektywnej oceny przyjmuje się dwa sposoby postępowania. Jeden to opisowa ocena ważności kryterium, drugi natomiast wymaga przyjęcia liczbowej skali pomiaru. Czynniki niemierzalne często pojawiają się przy planowaniu inwestycji. Możliwość ich uwzględnienia podczas podejmowania decyzji zapewniają nam różne metody wielokryterialne, np.: Analiza MCE, AHP, metody wskaźnikowe. Wszystkie wymienione metody wymagają zebrania dużej ilości informacji pozwalających ustalić wartości kryteriów. W tym celu przeprowadza się ankiety i wywiady wśród różnych grup ekspertów. Stosując metodę MCE musimy zebrać informacje o spełnieniu ograniczeń pierwszej i drugiej grupy. W przypadku ograniczeń pierwszej grupy do analizy służy skala zero- jedynkowa. 1 – oznacza spełnienie określonego wymogu, 0 – nie spełnienie. Przykładem takich ograniczeń może być: droga publiczna w odległości nie większej niż 5km; wielkość działki, na której planujemy budowę- co najmniej 1500 m2 i np. kryterium ekonomiczne – cena działki nie większa niż 150tys zł. W przypadku drugiej grupy kryteriów konieczne jest określenie skali umownej. Im szersza jest skala tym dokładniejsze określenie spełnienia danych warunków.

In the paper authors presented concept of evaluation of complex systems such as logistic companies which operate in competitive environment. Authors also highlighted the importance of the evaluation problem in operational activity, particularly in the properly prepared procedures to be followed, consisted of several stages adapted to currently conducted research. Properly executed evaluation of companies enables customers to take right decisions on contracting services and stimulate the development of those companies. It should be noted that the proposed algorithmic model of assessment may be particularly useful for assessment of complex logistics systems. Characteristics of the respective phases developed procedure allowed to indicate that it is important to select of appropriate criteria and evaluation methods. It was pointed out that particularly useful for assessing of logistics companies are multi-criteria analysis methods, because they allow to examine objects in a holistic manner, taking into consideration various aspects of activities such organizations. For the practical realization of assessment of logistics companies there was proposed Bellinger method, which contains quite transparent procedures. The results obtained from that method are consistent with those carried out by means of other, more complex multi-criteria methods. Also there was presented the problem of selection of weighted factors for the criteria in the context of their impact on the end result of evaluation. It was pointed out that the choice of an appropriate procedure for determining weights depends on the nature of the evaluated problem and form of criteria.

Opis:
The degree of emission limitation achieved through improved efficiency of combustion engine vehicles can no longer set off additional emissions caused by increasing traffic activity. As the restriction of greenhouse gas emissions from cars is expected to be particularly difficult, the air pollution and excessive dependence of road transportation on oil cannot be improved without the implementation of new mobility concepts (biofuels, hybrid drives, electric vehicles). The lack of these concepts, as emphasized in the White Paper, will preserve transportation dependence on crude oil so deeply that only 10% of energy will be derived from renewable sources. According to this scenario, until 2050 the CO2 emissions in the transportation sector will increase by one-third compared to 1990. Moreover, there will be an increase in the costs of traffic congestion until 2050 by ca. 50%. The difference in the availability between central and peripheral areas and social costs of accidents and noise pollution will increase as well (EC, 2011). The goal of the paper is to determine whether the implementation of a new solution would actually improve the situation of air pollution, traffic noise, etc. To this end, the paper proposes a comparative analysis of cars with various sources of energy using a multi-criteria scoring method. Notably, this method has never been used in such a confrontation before. Until now, the multi-criteria assessment methods have been used i.a. to evaluate implementation variants for infrastructural investment projects in rail transport (Jacyna and Wasiak, 2007), traffic flow distribution (Jacyna and Merkisz, 2014; Wasiak et al., 2017), supply chain efficiency (Jacyna-Gołda et al., 2018), effectiveness of vehicle allocation for tasks in supply chains (Jacyna-Gołda et al., 2017), etc.

Opis:
In modern society, people concern more about the evaluation of medical service quality. Evaluation of medical service quality is helpful for medical service providers to supervise and improve their service quality. Also, it will help the public to understand the situation of different medical providers. As a multi-criteria decision-making (MCDM) problem, evaluation of medical service quality can be effectively solved by aggregation operators in interval-valued q-rung dual hesitant fuzzy (IVq-RDHF) environment. Thus, this paper proposes interval-valued q-rung dual hesitant Maclaurin symmetric mean (IVq-RDHFMSM) operator and interval-valued q-rung dual hesitant weighted Maclaurin symmetric mean (IVq-RDHFWMSM) operator. Based on the proposed IVq-RDHFWMSM operator, this paper builds a novel approach to solve the evaluation problem of medical service quality including a criteria framework for the evaluation of medical service quality and a novel MCDM method. What’s more, aiming at eliminating the discordance between decision information and weight vector of criteria determined by decisionmakers (DMs), this paper proposes the concept of cross-entropy and knowledge measure in IVq-RDHF environment to extract weight vector from DMs’ decision information. Finally, this paper presents a numerical example of the evaluation of medical service for hospitals to illustrate the availability of the novel method and compares our method with other MCDM methods to demonstrate the superiority of our method. According to the comparison result, our method has more advantages than other methods.

Przedmiotem artykułu jest problem wyboru maszyn do wykonania robót montażowych. Wybór ten realizowany jest metodami MCDA, do których stosowania wykorzystuje się oceny rozwiązań przez pryzmat istotnych kryteriów z określeniem ich wag. W pracy przedstawiono wyniki badań ankietowych i ich analizę ustalające istotność i wagi kryteriów. Przeprowadzono badania wśród kierowników robót oraz planistów w polskich przedsiębiorstwach zajmujących się prowadzeniem robót montażowych, ustalając istotność 14 kryteriów 9 technologicznych i 5 związanych z preferencjami wykonawców lub czynnikami ekonomiczno-rynkowymi. Celem badań ankietowych było ustalenie miar istotności kryteriów decydujących o wyborze rodzaju żurawi budowlanych, oraz ocena żurawi względem tych kryteriów.
Crane selection is an important issue in assembly works planning. Tower and telescopic, stationary and mobile cranes used in construction have essentially different properties. Assembly planning begins in analyzing the possibilities of assembly with a given crane. This is called technical aspect of crane selection. Cranes that meet the technical criteria are then analyzed in terms of other criteria related to the effectiveness of their use on the construction site. The article presents the assessment of the selection criteria and the method of crane selection itself. Surveys conducted among construction managers and planners in Polish companies dealing with assembly works allowed to determine the significance of the selection criteria. For this purpose, an example using SAW (Simple Additive Weighting) and FSAW (Fuzzy Simple Additive Weighting) methods was presented. They also allowed to propose a technique for determining preferences in the use of selected construction cranes. The aim of the research was to increase the usability of computer applications supporting assembly planning by acquiring expert knowledge for the initial selection of organizational solutions.

Paper presents the issue related to the selection of slab formwork taking into account the criteria that are currently the most important The in the process of the construction project execution. The analysis included selected, modern system solutions, which significantly accelerate the tempo of reinforced concrete works and, as a consequence, increase the effectiveness of the construction project execution. The innovative system of drop heads, which the analysed slab formwork is equipped with, is offered by various formwork producers. The offered solutions, however, differ not only in the construction of the drophead itself, but also in the arrangement and variety of other system elements, as well as the scheme of their operation, which may ultimately significantly affect the effectiveness of their application. For that reason, the choice of formwork for specific buildings should be made from among carefully analysed several variants of the wide market offer. The paper presents the results of analysis and evaluation of formwork systems with dropheads according to the proposed methodology, including multi-criteria analysis.

In order to address the decision making issues, various multi-criteria decision making (MCDM) techniques may be implemented; and hence, they can be applied even when making a decision about an adequate logistics service center (LSC) placement in an examined territory (i.e., national logistics network of the selected territory), which is an aim of this manuscript. Following the statements above, as for the individual instruments of MCDM to be implemented in terms of the crucial objective of this research, the definite decision making process will be carried out by applying the Analytic Hierarchy Process (AHP) followed by the Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS), on the basis of criteria weights defined by the Saaty pairwise comparison method. The methods used appear to be ideal instruments towards decision making on the most suit-able location which is represented by the region in our case. Subsequently, these will be ordered from the most preferred to least one by using a preference ranking. As a result of the application of AHP and TOPSIS approaches, based on the conducted calculations in regard to decision making on identifying the proper LSC location out of eight selected regions, one specific region will be defined as the most suitable (so-called compromise) scenario. Individual tools allow for reducing the number of assigned criteria that are taken into account in searching process for individual solutions. In order to objectify the entire decision making procedure, ten topic-involved experts having practical experience with a subject of logistics object allocation will be asked to participate in the process. Preferences differ from one decision maker (expert) to another; hence, the outcome depends on who is making decisions and what their goals and preferences are.
