    The GAP of importance of design in business between 2014 and 2016
    (Technická Univerzita v Liberci, 2018-06-28) Kramoliš, Jan; Kotásková, Anna; Ekonomická fakulta
    In today´s very tough market struggle in the Czech Republic, more and more companies are aware that innovation is one of the key aspects leading to market success. The main research aim of this paper is to explore how “design” represents a business success trigger. This article examines the importance of four selected factors in the Czech Republic in 2014 and 2016 (design, quality, price, and reliability) in business success. Solutions were identified in two basic hypotheses (H1: Referring to the importance of design in relation to the success rate of the company, there is a difference between the companies conducting business in B2B and B2C markets; H2: Referring to the importance of design in relation to the success rate of the company, there is a difference among small, medium-sized, and large businesses) that were subject to statistical testing using chi-square and p-value. To evaluate results of the research, brief comparative analyses have been compiled. The conclusion builds on the authors’ 2015 study and shows changes researched on the issue of business importance. Design represents a very important competitive factor that influences their final decision. On the contrary, the company size specification does not influence the perception of the importance of design in Czech companies. The results clearly indicate only a minor shift. The “design” factor as the presumed business success trigger still has a weaker position compared to the rest of the examined factors. Quality and reliability have the strongest importance. In addition, there was a slight decline in the importance of the “product price” factor.

    Restructuring parcel delivery network by considering dynamic customer demand
    (Technická Univerzita v Liberci, 2018-06-28) Jin, Hyun-Woong; Ekonomická fakulta
    Parcel delivery service is one of the fastest growing industries in the world as the e-commerce such as online shopping mall expands rapidly. To increase its market share, most of parcel delivery service companies construct their delivery network as a form of hub-spoke network which is known to be efficient to deliver large scale products through widely spread area. In hub-spoke network, the number of hubs and their locations are important decision issues. Even though there are many researches on the hub-spoke network design, there is a lack of researches which deal with the fluctuating customer demand. Moreover, all the previous researches considering the fluctuating customer demand assumed that the capacity of hub facility is unlimited. Therefore, this research aims to propose the restructuring procedure of the parcel delivery network by considering the fluctuating customer demand with the capacitated hub facilities. In this research, utilization of temporary hubs is proposed so as to satisfy the fluctuating customer demand. Temporary hub responds to the excessive demands assigned to the permanent hubs and it is closed during the recession period to reduce its operating cost. A nonlinear integer programming model is constructed to decide the number of temporary hubs and their location at each time period. Since the complexity of the constructed mathematical model is NP-hard, GRASP based heuristic solution procedure is proposed. To evaluate the appropriateness of the proposed algorithm, experimental test with various demand sets considering four design factors are performed and the performance of the proposed algorithm is compared with the existing meta-heuristic algorithm. Test results show that the algorithm proposed in this research is more robust than the existing algorithm against the fluctuation of customer demand as well as it provides overall better results.

    (Technická Univerzita v Liberci, 2018-06-28) Nagyová, Ľudmila; Horáková, Monika; Moroz, Serhiy; Horská, Elena; Poláková, Zuzana; Ekonomická fakulta
    The dynamic development of foreign trade is important for the stable economic position. It can be considered as a confirmation of the actual efficiency of the national economy and its ability to be competitive in the global economics. In this paper, we analyze main tendencies of export trade of Ukraine with Visegrad countries and examine whether there is a relationship between the level of GDP and the volume of export activities between these countries. It should be noted that various agreements were concluded between Ukraine and each country of the V4 group regarding economic and trade relations. The main aim of this paper is to evaluate development of export of goods between Ukraine and Visegrad countries between years 2002-2013. The data of State Statistics Service of Ukraine, Eurostat and United Nations Conference on Trade and Development (UNCTAD) were used. The development of export from Ukraine to V4 countries is investigated using the software GRETL and log-log linear model. It is discovered that Ukraine’s export operations are impacted by export to other trade partners and GDP per capita of the country. The strongest positive link to Ukraine export from V4 group is represented by Poland. It is identified that, when the GDP per capita of the concerned country goes up, the export to that country declines. It is also revealed that there is a substantial difference with respect to export of agricultural commodities from Ukraine to the above-mentioned countries. To a significant extent, Ukraine’s export is oriented towards plant products. Ukraine should elaborate a well-defined trade strategy and extend its current export activities with V4 countries. It should be more deeply integrated into the EU’s market for using more efficiently possibilities, which exist in the frame of the signed Ukraine-European Union Association Agreement.

    Quality evaluation of internet websites which represents the lithuanian basketball through consumers approach
    (Technická Univerzita v Liberci, 2018-06-28) Ūsas, Antanas; Jasinskas, Edmundas; Štreimikienė, Dalia; Švagždienė, Biruta; Simanavičius, Artūras; Ekonomická fakulta
    The information technology area is one of the fastest expanding and most customizable in daily activities. In 2015, 68% Lithuanian households had personal computers and internet access at home. The modern business is moving to virtual space. The exchange of business area develops a need to managerial decisions in a virtual space. All of the e-business areas have one main element – website. In Lithuanian basketball websites carried out aid communication, information dissemination, representation, sales features. Web site can serve as a key platform to help organizations deal with clients (Gonzalez et al., 2015). The Organization Web site becomes the face of organization and represent in cyberspace. Because of large number of websites and the competition, aspect of quality becomes increasingly important. Main questions are: in what consumers pay attention? How they understand the benefits of the website? What kind of emotional state caused by the Web site? Analyzing techniques of websites evaluation three different groups were separated – quality, usability and satisfaction. The best technique – quality, which is the most universal and informative defining with other techniques. The quality of internet websites which represented the Lithuanian basketball satisfies the needs of consumers. The emotion which was experienced during the research was statistically insignificant influence but emotions experienced the last surfing minutes have statistically significant influence. Users, who had experienced positive emotions in the end of surfing, tend to evaluate better the internet website. It is important for organizations to manage their internet website that visitors leave it with positive emotions.

    Internet of things and its challenges in supply chain management; a rough strength-relation analysis method
    (Technická Univerzita v Liberci, 2018-06-28) Pishdar, Mahsa; Ghasemzadeh, Fatemeh; Antucheviciene, Jurgita; Saparauskas, Jonas; Ekonomická fakulta
    Internet of Things application (IOT) in supply chain management is becoming imperative and can shape a strategic competitive advantage. Albeit, different challenges appear through this application, most of the previous studies consider less about these challenges and focus on the advantages of IOT. To overcome this defect, different challenges that a supply chain may face as whole are determined based on systematic literature review and expert opinions. Then, a rough group decision-making and trial evaluation laboratory (DEMATEL) is applied. Advantages of the proposed model are that both internal strength and external influence of challenges and also vagueness and ambiguity of experts’ opinions are simultaneously noticed to completely show the importance of these challenges. The results show that challenges such as lack of strategy and scenario planning in IOT, storage issues, lack of security and lack of privacy are of great importance. So, these challenges should have a higher priority in attracting attention and resources. These results help managers to be equipped to face with main challenges in their path toward IOT in their supply chains. Accordingly some practical suggestions for managers are discussed in this paper, such as starting the journey toward IOT step by step, planning for a data storage system which is appropriate for big data, setting up a security policy to prevent out-coming problems caused by lack of security and privacy inherited by IOT, conducting a privacy or security risk assessment, minimizing the data collection and retain and testing the security measures before launching the products, and establishment of a legal framework to construct a problem-solving network in such a messed up and dynamic environment for processing such complicated huge data.
