A framework for managing future supply chain trends: utilization of lean, agile and leagile strategies
Waleed Rashad, 2020, doktorska disertacija

Opis: The supply chain has become very essential to run any business nowadays. Throughout the history of business, the professionals have been trying always to find out the best practice, and as long as the business concept is evolved over time, the practice, methodologies and techniques of doing the business also have been evolved. This evolvement led to the concept of supply chain initially and then later it became essential to have strategy for supply chain. The evolvement of the markets, globalization, and new technologies became very decisive subjects for building any supply chain and developing its strategy, but there are many other events that may take place which could enforce the supply chain decision makers to change the current approach of running their business. The dynamic business environment and the possible future trends of the global markets represent a real challenge for development of appropriate supply chain strategies, like lean, agility, and leagility. Therefore, it is very important to assess how different possible strategies are suitable for the future changes of the markets? This is to enable the supply chain to be prepared with adequate strategies for different future scenarios. To achieve this aim of preparing the supply chains for the future with adequate strategies, a deep study is done to research lean, agility and leagility, explaining the similarities and differences of these concepts. These strategies are dealing with the most important factors in supply chains; the time and the cost, what is the key reason for selecting these particular strategies lies in the fact, that they are concerned with improving the effectiveness and responsiveness in the supply chain and this is extremely important for the future. We continued study of these strategies by development of three possible future scenarios for energy scarcity, new international monetary system, and wars. The reason of developing these particular scenarios is because they are concerned with the most important political and economic events which could happen and affect the supply chains in the future (EY, 2013; Cook, 2006; Sokov, 2015). These scenarios are established to anticipate the possible challenges which could face the supply chain strategies in the future and to evaluate the suitability of supply chain strategies for such future scenarios. A survey of 150 supply chain professionals, who are working currently in the field of supply chain management, is done in two phases. The first phase is focusing on recognition of the opinions of surveyed supply chain professionals towards the supply chain strategies and their utilization. Based on the theoretical knowledge of the academic literature reviewed in this research, proposed scenarios, and the feedback of professionals in the survey, it was evident that supply chains’ managers need adequate framework, which will support improvement of current and future supply chain management. Therefore, the grounded theory methodology is used to create a new conceptual framework. The core idea of the proposed framework is to improve the global sourcing practice, which consequently will enable improving the management of supply chains according to the predicted scenarios. A second phase of survey is conducted to present the proposed framework to the supply chain professionals for evaluation. The proposed framework adds value to the global sourcing process, which enhancing the supply chain collaboration and helps to support the selected supply chain strategies for consideration – i.e., lean, agility, and leagility, to work better in the future. The proposed framework represents scientific contribution to the supply chain strategies utilization in practice. The results of this contribution are obviously to fill the gap highlighted by the supply chain professionals in the survey, who highlighted the essential need for improvement to the supply chain collaboration globally, and this will be the basic c

Global sourcing strategies
Waleed Rashad, Zlatko Nedelko, 2020, izvirni znanstveni članek

Opis: The main purpose of this paper is to develop a framework for utilization of lean, agile, and leagile strategies in the supply chains, where the core idea of the framework is to improve the global sourcing practices. Based on in-depth interviews with supply chain professionals and grounded theory approach, we constructed a framework of global sourcing improvement to support better utilization of lean, agile, and leagile strategies, which we believe can help the supply chains worldwide to act better, especially in various difficult conditions and sustain their business accordingly. Our proposed framework also contributes to the UN´s Sustainable Development Goals, since the core concept of the framework is to establish a new organization under the umbrella of the UN to improve the global sourcing and consequently the usage of supply chain strategies accordingly. The applicative part of the paper reveals characteristics of new developed framework, ranging from its purpose and aims, structure, key processes, functions, and its financing. Along with validation of the framework are presented benefits for society, industry, and global economy. Additionally, the paper also reviews the impact of the current health and economic crisis caused by COVID 19, on usage of the three supply chain strategies namely; lean, agility, and leagility to see how they can work in the difficult time, as COVID 19.

Fragmented Romanian sociology: growth and structure of the collaboration network
Marian-Gabriel Hâncean, Matjaž Perc, Lazǎr Vlǎsceanu, 2014, izvirni znanstveni članek

Opis: Structural patterns in collaboration networks are essential for understanding how new ideas, research practices, innovation or cooperation circulate and develop within academic communities and between and within university departments. In our research, we explore and investigate the structure of the collaboration network formed by the academics working full-time within all the 17 sociology departments across Romania. We show that the collaboration network is sparse and fragmented, and that it constitutes an environment that does not promote the circulation of new ideas and innovation within the field. Although recent years have witnessed an increase in the productivity of Romanian sociologists, there is still ample room for improvement in terms of the interaction infrastructure that ought to link individuals together so that they could maximize their potentials. We also fail to discern evidence in favor of the Matthew effect governing the growth of the network, which suggests scientific success and productivity are not rewarded. Instead, the structural properties of the collaboration network are partly those of a core-periphery network, where the spread of innovation and change can be explained by structural equivalence rather than by interpersonal influence models. We also provide support for the idea that, within the observed network, collaboration is the product of homophily rather than prestige effects. Further research on the subject based on data from other countries in the region is needed to place our results in a comparative framework, in particular to discern whether the behavior of the Romanian sociologist community is unique or rather common.

Community structure and the evolution of interdisciplinarity in Slovenia's scientific collaboration network
Borut Lužar, Zoran Levnajić, Janez Povh, Matjaž Perc, 2014, izvirni znanstveni članek

Opis: Interaction among the scientific disciplines is of vital importance in modern science. Focusing on the case of Slovenia, we study the dynamics of interdisciplinary sciences from 1960 to 2010. Our approach relies on quantifying the interdisciplinarity of research communities detected in the coauthorship network of Slovenian scientists over time. Examining the evolution of the community structure, we find that the frequency of interdisciplinary research is only proportional with the overall growth of the network. Although marginal improvements in favor of interdisciplinarity are inferable during the 70s and 80s, the overall trends during the past 20 years are constant and indicative of stalemate. We conclude that the flow of knowledge between different fields of research in Slovenia is in need of further stimulation.
