Thus, risk assessment often needs to be prepared and conducted according to the principle of uniqueness, distinction, etc. Each risk requires the identification of a number of sources not found in the other types of risks. That is why the purpose of the article is to develop and improve methods of the analysis and the assessment of investment risks requiring the further refinement. On the basis of systematization and the comparative characterization of existing methods of risk assessment and analysis used in the modern economic practice of investment activities, it is proposed to improve the tools for risk analysis and assessment by including the empathy method, which allows using not only the economic criteria, but also a combination of subjective and objective cognitive assessments of an investor. The article suggests to consider «risk perception» as two separate components: risk perception and risk opportunity perception taken into account the conditions affecting the perception that one of the investment risks will be lower or higher in a certain period of time or at a certain stage of investment, regardless of the risk profile. The perception of a risk opportunity is positive for investing, although at the same time it has its own negative consequences for a developing enterprise. The impact on this can only be identified once the risk profile has been determined at the stage when the enterprise has specific proposals and prospects for attracting investment. The totality of factors making up the risk «profile» has already been considered many times in risk assessment methodologies, and is supplemented by new components such as «tolerance» and «perception» of risk, which were not previously applied in relation to investment risk. Consequently, the suggested empathy method for risk assessment and analysis allows to take into account the influence of perceptions, tolerance and risk attractiveness, which will ultimately generate a clear and logical risk profile and enables to find out which of these factors have the greatest and the indirect influence on the decision to invest.","PeriodicalId":372796,"journal":{"name":"Economics of the transport complex","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124582073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is established that effective management of production processes and logistics of any enterprise is not possible without determining the relevant and structured information about the state of the elements of the supply chain and the processes that take place in it. It is researched and formulated that the generally accepted system of measuring the efficiency of the enterprise is a balanced system of key indicators of supply chain efficiency. But based on the analysis of different points of view of scientists, it is determined that to assess the effectiveness of supply chains of enterprises, the vast majority of scientists suggest using ten key indicators, namely: service quality, product quality, lead time (response rate), overall logistics costs, financial indicators ), value added, reliability, flexibility (maneuverability), power, assets. The differences between the SCOR model used at the three levels of metrics, which are designed to assess the effectiveness of decisions at the strategic level, have been studied and established. At the first level, there are indicators that characterize the general state of the supply chain – key performance indicators (KPI – Key Performance Indicator). At the second level – indicators that help diagnose level 1 indicators and identify deviations. The third level of indicators diagnoses the indicators of the 2nd level, respectively. In this case, all metrics must have a hierarchical structure. It is established that the main differences between the concepts of efficiency and effectiveness of supply chains are that efficiency is associated with minimizing all related resources and processes, while efficiency is aimed at achieving all goals, higher results, completed activities and customer satisfaction, focusing on the customer and the goal as much as possible, thus achieving supply chain optimization. Effectiveness is the highest attempt to reduce all resources by maximizing the use of all capacities, the response tries to be as flexible and customer-oriented as possible. A matrix of efficiency of supply chains is proposed, which takes into account the indicators of their efficiency. Efficiency and effectiveness can improve the productivity of the supply chain through enhanced collaboration with all relevant actors.","PeriodicalId":372796,"journal":{"name":"Economics of the transport complex","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127512052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transition from the functional approach to management used in the concept of viable systems to a more progressive process approach is justified, which will increase the versatility of the developed model. The enterprise management system is presented in the form of a metasystem (management entity) and an operational element (management object). The object of management is presented in the form of a system of management of MTE ecological innovations portfolios (subsystem of operational management). These projects are implemented in five basic business processes of the motor-transport enterprise: the main production processes; related processes; auxiliary processes; security processes; business processes management and development. The model of a viable system of ecological and innovative management of MTE provides development of a complex of models which ensure efficiency of introduction of ecological innovations in business processes of the enterprise. The use of the proposed model allows to increase the consistency, efficiency, accuracy, adequacy of management decisions; stability of functioning and adaptation to changing conditions of external and internal environment; increase the predictability and transparency of environmental innovation activities of the MTE, which improves the efficiency and effectiveness of the enterprise.

The strategic priorities of European transport policy are integrated to other EU development priorities, including the European Green Deal, Territorial Agenda 2030. In December 2020 The European Commission presented “Sustainable and Smart Mobility Strategy – putting European transport on track for the future”. This document has outlined the European transport system’s path towards achieving objectives of a sustainable, smart and resilient mobility. The priorities of the European transport system focus on environmental issues, sustainability, development of high-speed railways, expansion of rail freight and passenger transport markets, development of multimodal transportation, technologies for a further electrification and automation in transport, digitalization, deployment of innovations. Road freight transport accounted for more than two thirds of freight traffic in 2019. For the EU member states bordered to Ukraine (Poland, Slovakia, Hungary, Romania), the share of road freight transport has been growing since 2011. These countries are mostly involved in the international road freight transportation. The average distance for which goods were carried by international road freight transport in EU was 581 km in 2018. For Poland, Hungary, Slovakia and Romania the average distance varied from 603 to 786 km. The countries that have joined the EU since 2004 accounted for 80 % of all cross-trade in the EU, which emphasized on the relative competitiveness of hauliers from these countries. Transport companies from Poland are the most active in freight transport between EU countries, in particular in cabotage. In 2020, the European Parliament adopted the Mobility Package I.
