    In the contemporary highly competitive international business environment companies have to exercise great care in devising entry strategies for foreign markets. Therefore, supply chain management (SCM) is considered a strategic factor for the better attainment of organizational goals such as enhanced competitiveness, improved customer service and increased profitability. Because the, Supply chain management as a vital challenge to the Cement industry and developing infrastructure as a whole has been posed by scholars. This article analyses Lean, Agile, Resilient, and Green (LARG) supply chain management competitive strategies in Iranian cement industries. The lean, agile, resilient and green SCM paradigms had been adopted to improve the SC performance. We used Step-wise Weight Assessment Ratio Analysis (SWARA) technique to weighting strengths, weaknesses, opportunities and threats (SWOT) based on LARG supply chain management practices for 11 Iranian cement companies. Then the Strategic Position and Action Evaluation (SPACE) matrix used to check if which strategy is appropriate. In the SPACE matrix we assessed Iranian cement industries across four dimensions include: Industry Attractiveness (IA), Environmental Stability (ES), Competitive Advantage (CA) and Financial Strength (FS). The results showed that Iranian cement industries can follow an aggressive strategy as it leverages its strengths into the opportunities. Iranian cement industries are also blessed because it has a good competitive advantage in an industry which is considered to be attractive. Among the strategic choices, develop new local markets strategy has the first priority, followed by the; Increase production capacity, Export markets development, Diversification in product with QSPM method. Finally, some actions recommended for Iranian cement industries in such a strong position.

    (Technická Univerzita v Liberci, ) Heidary Dahooie, Jalil; Mohammadi, Navid; Mohammadi, Mehdi; Shahmohammadi, Parisa; Turskis, Zenonas; Šaparauskas, Jonas; Ekonomická fakulta
    Patent valuation and prioritization is one of the main activities for the management of intellectual property assets in an organization. So far, numerous attempts have been made to determine the value of patents, some of which have not been efficient due to ignoring some effective dimensions or considering the same importance for all aspects. To overcome this challenge, this research aims to provide a framework for valuing and prioritizing patents using a combination of MADM methods. For this purpose, first, the indicators for patent valuation and prioritization were taken from the literature and aggregated and finalized based on opinions of experts of technology management as well as nanotechnology in the form of a Delphi method. Second, the indicators were weighted, and their importance specified based on expert opinions using the questionnaire tool and stepwise weight assessment ratio analysis (SWARA) method. Third, the additive ratio assessment (ARAS) method was used to value and prioritize the patents. For this reason, 12 nanotechnology patents, registered in 2016 at the Iranian Administration of Registration of Documents, were valued and ultimately prioritized. The results from the criteria weights indicate that commercial and market potential and the economic value should be selected as the most critical dimensions. Also, among the indicators, the project investment cost, the costs of production and commercialization and the economic relevance, were selected as the most critical indicators. Among the 12 patents examined, "Gelatin-Chitosan/Carbon Nanotube Composite Scaffolds for Bone Tissue Engineering Applications" was identified as the most valuable patent.

    Ranking of priorities among the baltic capital cities for the development of sustainable construction
    (Technická Univerzita v Liberci, 2015-06-03) Lazauskas, Marius; Zavadskas, Edmundas Kazimieras; Šaparauskas, Jonas; Ekonomická fakulta
    Crisis of the real estate sector resulted in disadvantageous conditions for legal entities operating in the fi eld of construction and implementation of new property development projects. As a result, many such entities started investigating their options to offer construction services and products to more economically attractive foreign markets. This necessitates the need to assess the effectiveness of investments into new markets, considering the current developmental trends of the construction sector, which are related to implementation of sustainable construction projects. Close cooperation of Baltic States at the national level and joint activities of several construction market participants predetermine the necessity to assess biggest cities of Lithuania, Latvia, and Estonia being the potential market of construction sector to be selected as a target segment of effi cient development of construction needs.These are the reasons behind the creation of a typical calculation model, which could be adapted for an effective and uncomplicated assessment of investment rationale in new markets while ensuring the adherence to principles of sustainable development. Assessment of potential capabilities of a construction sector of three Baltic capitals (Vilnius, Riga, Tallinn) could provide the opportunity to direct capital and investments of construction market participants in the wore effi cient way and create the highest added value for the economy, residents and development of sustainable environments. Identifi cation of project implementation area is a key factor in determining directions of the activity performed by private investors, performed in order to assess the opportunity of effi cient realisation of construction project proposed for implementation with particular environment. A multiple-criteria task is formulated, which aims to determine the rank of priorities among cities of the Baltic states; and multi-criteria methods MOORA and MULTIMOORA are used for decision-making.

    Research on the demand for parking lots of shopping centres
    (Technická Univerzita v Liberci, 2016-09-23) Palevičius, Vytautas; Burinskienė, Marija; Podvezko, Valentinas; Paliulis, Gražvydas Mykolas; Šarkienė, Edita; Šaparauskas, Jonas; Ekonomická fakulta
    Over the last decade, in the cities of Lithuania the number of shopping centres has been increasingly growing, they were provided with large parking lots. The development of shopping centres has formed a new structural and very concentrated urban element the result of activity of which has not been widely studied from the transportation point of view. When implementing a sustainable urban development the authors of the article aimed at ensuring the effective use of the parking lots of shopping centres during twenty four hours. For this purpose, an empirical research was carried out which resulted in a comprehensive analysis of the parking lots of 49 shopping centres in Vilnius City. The research used observation method to determine a design capacity of the parking lots of shopping centres, their occupancy, to additionally define the number of residents living in the closest proximity to the parking lot, the number of flats, the value of flats, the number of working population, the demand for parking spaces, occupancy of the parking lots with cars, etc. The expert method was used to select the main criteria characterizing interaction of the parking lots of shopping centres with the multi-storey housing area. With the help of expert questionnaire the weights and significances of criteria were determined. Using the multiple-criteria methods a priority use of the parking lots of shopping centres for parking of passenger cars was calculated and assessed. The article gives development priorities and outlines the strategy of implementing the given recommendations. This is one of the first attempts to use the parking lots of shopping centres to park passenger cars at night. If the suggested system is put into practice it would help to reduce up to 20% the demand for parking spaces in the urbanized multi-storey housing areas.

    Sustainable Construction Supplier Selection by a Multiple Criteria Decision-making Method with Hesitant Linguistic Information
    (Technická Univerzita v Liberci, ) Liao, Huchang; Ren, Ruxue; Antucheviciene, Jurgita; Šaparauskas, Jonas; Al-Barakati, Abdullah; Ekonomická fakulta
    Within the context of resource constraints and ecological environment imbalance, the adoption of green suppliers can help construction enterprises achieve sustainable development and improve their competitiveness. The selection of sustainable construction suppliers is a multi-criteria decision-making problem since multiple factors should be considered. The increasingly complex decision-making environment makes it difficult for evaluators to give accurate evaluation values. In this regard, the hesitant fuzzy linguistic term set is a qualitative evaluation tool to represent the comprehensive linguistic evaluation values of experts by considering the hesitancy behaviors of experts. In this paper, a scientific multi-criteria decision-making model based on the improved Stepwise Weight Assessment Ratio Analysis (SWARA) method and the double normalization-based multi-aggregation (DNMA) method in the hesitant fuzzy linguistic environment is proposed. A new distance measure is proposed to measure the differences between hesitant fuzzy linguistic term sets with different lengths without changing the original evaluation information of experts. The proposed distance measure is applied to the proposed multi-criteria decision-making model. After improving the calculation steps of the traditional SWARA method, we can determine the weights of criteria effectively through our proposed model. To verify the applicability of the proposed method, we implement it to select sustainable building suppliers. The effectiveness of the method is verified by sensitivity analysis. We also compare the results obtained by our method and those derived by the Weight Aggregated Sum Product ASsessment (WASPAS) method and the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method. The proposed method have a strong applicability to solve the sustainability-related decision problems given that it can effectively determine the weights of criteria and flexibly meet the needs of decision-makers by adjusting the coefficient.

    TOWARDS AN EFFICIENT APPROACH FOR IDENTIFICATION AND SELECTION OF STAKEHOLDER ENGAGEMENT STRATEGIES: A CASE STUDY
    (Technická Univerzita v Liberci, ) Khalilzadeh, Mohammad; Kebriyaii, Omid; Šaparauskas, Jonas; Lepkova, Natalija; Ekonomická fakulta
    The goals and objectives of a project as well as the needs, requirements and expectations of the project stakeholders may contradict or non-fulfillment of them may have different detrimental and negative consequences for the project. Therefore, project stakeholders should be effectively managed, but it is not possible to satisfy all project stakeholders and meet all of their expectations and requirements. As a result, project team must strike a balance between the project goals and objectives and the needs, requirements and expectations of the project stakeholders in order to complete the project successfully. Despite highlighting the significant importance of project stakeholder management, there exists a notable gap in exerting an effective decision support system to adopt stakeholder engagement strategies particularly in oil and gas construction projects. This study proposes a comprehensive framework for the identification, prioritization and selection of the stakeholder engagement strategies in one of the large size oil and gas construction projects in Iran. In this paper, a hybrid method which is the combination of the SWOT (strengths, weakness, opportunities and threat) analysis and fuzzy Delphi method is first exploited for identifying the appropriate stakeholder engagement strategies. Subsequently, fuzzy SWARA (Step-wise Weight Assessment Ratio Analysis) is employed to weight the crucial criteria, and finally, fuzzy WASPAS (Weighted Aggregated Sum Product Assessment) is utilized to prioritize the identified stakeholder engagement strategies. This research contributes to the body of knowledge on project stakeholder management by presenting a novel framework for identifying, ranking and selecting the suitable strategies for effective stakeholder engagement considering one of the largest oil and gas construction projects in the country. The value of this study is in applicability of the proposed methodology for project managers and practitioners in other oil and gas construction projects.
