ASSESSMENT OF HEALTH AND SAFETY SOLUTIONS AT A CONSTRUCTION SITE

AbstractTo design solutions for occupational safety at a construction site for the construction technology project, an occupational hazard was assessed. Possible solutions for occupational safety depend on the number of criteria such as hazardous factors from which workers must be protected; the number of danger zones; architectural-design and structural solutions of a building; types of technical protection measures, etc. A large set of solutions for occupational safety predetermines the number of respective typical (or repeated) solutions, which are based on specific technical safety measures and are applicable depending on a hazardous factor; besides, it determines systematisation of the solutions on these grounds. It is suggested to use the Multiple Criteria Decision Making (MCDM) technique for assessment and selection of appropriate solutions for occupational safety. The authors propose formulating assessed alternatives from the typical solutions to ensure their quality and then apply the entropy met...

Solving the problems of daylighting and tradition continuity in a reconstructed vernacular building

AbstractSeeking for saving traditional forms, sizes, proportions and other features of vernacular architecture and satisfying norms for a contemporary building sometimes is not an easy task. The presented case study about indoor daylighting in Lithuanian vernacular architecture shows the existing problem. The authors of the article suggest possible variants of how to improve daylighting in vernacular buildings. The aim of the conducted research is to propose a rational solution to the problem using multiple criteria assessment. Alternative variants can be characterized by a number of quantitative and qualitative criteria. Thus, for ranking alternatives and achieving the most rational solution, the use of the Analytic Hierarchy Process (AHP) to evaluate the relative importance of criteria as well as the application of Multiple Criteria Decision Making (MCDM) methods are put forward. The case study presents possible alternatives for improving daylighting in the reconstructed building and simultaneously anal...

Upgrading the old vernacular building to contemporary norms: multiple criteria approach

AbstractSustainable development is emphasized in the process of construction or modernization of buildings at present. Old vernacular architecture does not satisfy contemporary building norms such as daylighting and/or thermal performance parameters. These parameters are important for sustainability due to their relation with energy savings. It is obvious that seeking to improve these parameters, old buildings should be upgraded. The main problem is how to reach contemporary building norms without a negative impact to architectural heritage in a process of modernisation. The aim of the research is to find the best compromise solution for effective vernacular architectures change. The Authors suggest using multiple criteria approach that enables to evaluate possible alternative solutions in several controversial aspects and to find rational buildings modernisation type. Also, suitability of combination of usual MCDM (Multiple Criteria Decision Making) methods with grey systems theory due to possibility o...

Using fuzzy Choquet Integral operator for supplier selection with environmental considerations

The increasing importance of considering environmental issues as a part of the corporate social responsibility, which has environmental and social impacts as well as affects the image and competitiveness of a firm, has encouraged companies to revise their major processes of supply chain management (SCM). Since the performance of a company heavily relies on its suppliers, it is of vital importance to incorporate environmental criteria into supplier selection problem to satisfy both conventional and environmental criteria, which have only been considered by a limited number of studies. Therefore, following a brief review of green supply chain management (GSCM) and sustainable supply chain management (SSCM) concepts and investigation of supplier selection approaches, this study after focuses on a modified Delphi method that has been applied to determine supplier selection criteria. Also, the intuitionistic fuzzy value (IFV) and interval value intuitionistic fuzzy (IVIF) have been utilised for supplier evaluation regarding the subjective nature and uncertainty of judgment. By using the Choquet Integral operator and fuzzy measures, the best supplier has been selected, and the comparison between IFV and IVIF has been made. This methodology has been applied to a manufacturing company to assess the applicability of the proposed methodology. The proposed methodology can be used for real world problems that contain fuzziness or interacting decision criteria. Moreover, due to a high level of expert involvement in the decision-making process, we claimed that the knowledge of experts has been utilised constructively.

FQSPM-SWOT for strategic alliance planning and partner selection; case study in a holding car manufacturer company

In today’s competitive environment, holding companies are usually unable to successfully compete in production of goods and services due to technological sophistication. Therefore, for success of holding companies, selecting appropriate strategic alliance partner is a critical factor. Accordingly, the aim of the paper is to propose a systematic approach for an effective partner selection. Firstly, the underlying motivation and reasons for a strategic alliance building are presented using a SWOT analysis. Criteria of partners’ evaluation are attained on the basis of combining strengths, weaknesses, opportunities and threats. Due to uncertainty of criteria, they are weighted using fuzzy quantitative strategic planning matrix (FQSPM). Because of a large number of criteria obtained from the SWOT-FQSPM analysis, criteria are diminished based on their weights using the Gap analysis with fuzzy data ranking. In the next step, it is proposed to apply four ranking algorithms including the Fuzzy Additive Ratio Assessment (ARAS-F), the Fuzzy Complex Proportional Assessment (COPRAS-F), the Fuzzy Multi-Objective Optimization by Ratio Analysis (Fuzzy MOORA), and the Fuzzy Technique for Order Preference by Similarity to Ideal solution (Fuzzy TOPSIS) to evaluate strategic partners. Finally, the results are combined with the help of the Borda method to choose the best alternative. To illustrate the efficiency of the proposed approach, a real partner selection problem at a holding industries factory in Iran is presented.

Assessment of third-party logistics providers using a CRITIC–WASPAS approach with interval type-2 fuzzy sets

The assessment of Third-Party Logistics (3PL) provider becomes an important issue for enterprises trying to achieve operational efficiency and customer service improvement as well as capital expenditure and logistics costs reduction. It can be said that evaluation and selection of an appropriate 3PL provider is a kind of Multi-Criteria Decision-Making (MCDM) problem. Uncertainty is an unavoidable part of information in the decision-making process. Interval Type-2 Fuzzy Sets (IT2FSs) are very flexible to model the uncertainty of the MCDM problems. In this study, a new integrated approach based on the criteria Importance Through Inter-criteria Correlation (CRITIC) and Weighted Aggregated Sum Product assessment (WASPAS) methods is proposed to evaluate 3PL providers with IT2FSs. In the proposed approach, objective weights resulted from the CRITIC method are combined with subjective weights expressed by decision-makers (dms) to determine more realistic weights for criteria. A computational study is performed to illustrate the proposed approach and the applicability of it. In addition, a sensitivity analysis is carried out using different sets of criteria weights to demonstrate the stability of the proposed approach. The results show the stability of ranking results and prove the efficiency of the proposed approach to handle MCDM problems with IT2FSs.

Fuzzy extension of the CODAS method for multi-criteria market segment evaluation

AbstractOne of the important activities of a company that can increase its competitiveness is market segment evaluation and selection (MSE/MSS). We can usually consider MSE/MSS as a multi-criteria decision-making (MCDM) problem, and so we need to use an MCDM method to handle it. Uncertainty is one of the important factors that can affect the process of decision-making. Fuzzy MCDM approached have been designed to deal with the uncertainty of decision-making problems. In this study, a fuzzy extension of the CODAS (COmbinative Distance-based ASsessment) method is proposed to solve multi-criteria group decision-making problems. We use linguistic variables and trapezoidal fuzzy numbers to extend the CODAS method. The proposed fuzzy CODAS method is applied to an example of market segment evaluation and selection problem under uncertainty. To validate the results, a comparison is performed between the fuzzy CODAS and two other MCDM methods (fuzzy EDAS and fuzzy TOPSIS). A sensitivity analysis is also carried out...

PRINCIPLES OF REVITALISATION OF DERELICT RURAL BUILDINGS

Abstract The problem of Lithuanian derelict and mismanaged rural buildings that have a negative influence on the economy and environment of the country is analysed in the paper. Revitalisation of unused rural buildings is analysed in a context of sustainable development. Factors determining distribution and revitalisation perspectives of unused buildings were established by using methods of mathematical statistics. It was estimated that the peculiarities of territorial distribution are different in various zones of different development activity, also they differ according to the uses of buildings. Analytical review of sustainability indicator systems was performed. The model of indicator system for revitalisation of derelict rural buildings is proposed in the paper. This indicator system was worked out according to the common principles of sustainable development and to local peculiarities, explored by analysing territorial distribution of objects. It is possible to rate the priorities of building revita...
