KONEPS is the National Comprehensive Electronic Procurement System of the Public Procurement Service. If KONEPS can know the bidding possibility and trend before bidding, it will be more efficient for companies to bid. In this paper, we used in the experiment was the data of "Progress Bidding Classification" of the Procurement Information Open Portal. And preprocessing process was performed to facilitate prediction model learning. Prior to learning, preprocessed 1,158 data sets were normalized to match the range of data or to make the distribution similar. After normalization we select the number of cluster. As a result of K-Means Clustering, Biddropping is 77 ~ 80%, Budget Allocated is about 2 billion Won(₩), Biddropping is 83 ~ 87%, Budget Allocated is about 1 billion won, bid dropping is 87 ~ 90% Budget Allocated is distributed around 500 million won. And can be confirmed that the cluster is divided based on the number of enterprise 58. Through the results, it is possible to study the tendering trends through the community by learning the prediction models of the bidder companies, the number of bidders, and the tendency of the bidding business, and it will help KONEPS to develop the next generation ISP.

Abstract Treaty of Rome of 1957 and following treaties on amending the Treaty of Rome contain a number of basic principles on which the EU is founded. Among these principles, the most important ones related to the public procurement are: prevention of discrimination based on nationality, free movement of goods; right and freedom of establishment of a business; the right to provide services. Spending of public money in Kosovo pursuant to the Law on Procurement is found on the following principles: economization and efficiency; equal treatment and non-discrimination; transparency; value for money. The average of open procedure application in EU countries is 73% based on notices, whereas in Kosovo is 82.80% based on notices. In the end of 2014, Kosovo commenced the development of electronic procurement platform. This project takes place within the Public Sector Modernization Project. The importance of the electronic procurement is stated in the statement of European Commission: “Modernization and opening of procurement markets across borders - including through the electronic procurement expansion - are crucial for the competition in Europe and creating new opportunities for businesses in EU”. A good procurement system in Kosovo will have an impact on elimination of negative phenomena (corruption and bad management) in the management of public expenditures from spending agencies, as well as an impact on increase of budget saving.

The issue of reforming the institute of state (public) procurement is one of the key directions of the modernization of the administrative sector of our state. Increasing the efficiency of this institute should be recognized as one of the conditions for ensuring stable economic growth. In this regard, issues relating to the assessment of the efficiency of the use of public funds are of particular interest. The indicators of the efficiency of the activity of the public procurement sector in Ukraine in the context of the introduction of the “ProZorro” electronic procurement system are calculated and analyzed. The existing works of the individual scientists in the direction of developing indicators of the efficiency that can be used to evaluate the results of the operation of the procurement logistics system in the public sector in Ukraine are generalized. As a result, approaches have been identified that can be used to determine the effectiveness of the participation of customers, private sector representatives and the system of electronic public procurement in general. On the basis of retrospective data of past years and the first half of the current year, a number of estimates of absolute and relative savings, as well as indicators of the effectiveness of the open bidding in the public sector of Ukraine have been identified. The dynamics of these indicators before and after the introduction of the “ProZorro” electronic procurement system was analyzed. The analysis shows that the first results of the functioning of the “ProZorro” system demonstrate the existence of negative trend of competition and reduction in the amount of savings in public funds. Ensuring high efficiency and competitiveness, integrity and transparency of the procurement process are the main tasks of the Ukrainian government in the field of public procurement. The authors argue that the introduction of the “ProZorro” system can help to solve them successfully, and the application of the analytics module enables to calculate the savings from the use of this system.

Procurement System

In almost every country, public procurements are the primary issue which citizens are the most sensitive to in terms of how public money is spent. Electronic procurement systems in the public sector have been adopted as a solution in order to respond to the sensitivity of citizens because of the benefits promised. In the early 2000s, Turkey both made the public procurement legislation approximate to the European Union standards and began to develop an e-procurement system within the scope of e-transformation Turkey project. As a result of the works carried out under the leadership of the Public Procurement Authority, which is an independent administrative authority, the e-procurement system started to be used in some stages of the procurement process. Four public hospitals were determined as pilot administrations in order to improve the implementation and it was aimed to make the implementation common in all sectors according to the experiences gained in this field. The objective of this chapter is to reveal benefits gained and barriers faced during the development process of the e-procurement by focusing on the above mentioned pilot implementation field. In order to attain this objective, the method of case study was adopted in this research, and guiding experiences were tried to be gained for the e-procurement implementations in the future.

<p><strong>Theoretical background</strong>: There is an ongoing global acceleration of automation and digitalisation in financial processes, which points to significant changes in public spending policies. After an analysis of several scientific studies, fundamental approaches have been elaborated to understand public consumption and the system of state purchases. The basic hypothesis for this research was to study the possible impact of the electronic procurement market ProZorro on state purchases in Ukraine. Possible directions are: increasing competitiveness, optimising state expenditures and saving the budget funds of public services based on innovative digital technology.</p><p><strong>Purpose of the article</strong>: The main goal is to investigate the impact of the electronic public procurement system ProZorro on corruption and bureaucracy in the public sector of Ukraine. The study object is an analysis of the volume and structure of the public procurement market, the number of procedures and participants in a bidding process, and the savings amounts in ProZorro’s public purchases during the study period in Ukraine.</p><p><strong>Research methods</strong>: The following methods were used during the research of the Ukrainian electronic procurement system: dialectical method; analysis and synthesis method – for a comparison of certain types of public procurement; subthreshold and suprathreshold statistical methods – for analysing the dynamics of indicators of the domestic system of public procurement during the period under research for a comparison of the indicators of public consumption of certain ministries and departments, different regions and territorial entities; structural and logical analysis – for generalising the theoretical and methodological principles of building a public consumption system in Ukraine. The main source of data was the data and analytical base of the ProZorro electronic public procurement system.</p><p><strong>Main findings</strong>: Effects of the innovative digital paradigm on the transparency and efficiency of public procurement are determined. Considerable attention is paid to the implementation of the electronic public procurement system ProZorro in Ukraine. The expediency is substantiated for its implementation in the national practice of budget expenditures, and the principles and procedures of implementation are analysed. The practice and dynamics of the public procurement market in Ukraine are summarised. The conclusions of the advantages of electronic system are provided, including transparency and impartiality, stimulation of competition and non-discrimination of bidding participants, reduction of corruption and the effect of reducing the savings of budget funds. Potential risks, threats and disadvantages of the ProZorro system in Ukraine are highlighted. Among them are: a high proportion of non-competitive procedures; possible latent conflict regarding the participants’ interests; unreasonable time spent on individual procedures; the justification of the procurement procedure to one participant due to a dubious “urgent need”; unreasonable application of the procurement procedure to one participant due to the falsification of conditions or the division of the procurement subject; the existence of discriminatory requirements in the documentation of competitive bidding; and a lack of efficiency in the complaints handling mechanism.</p>

Weak Independence

Abstract. Introduction. Any political system exists as a set of institutions and organizations that are collectively responsible for social organization and assuming various managerial functions. Since the fundamental task of the state is to ensure sustainable economic development, the processes that can ensure certain economic shifts are almost a defining component of economic policy and are urgent. Ukraine, striving for real change, did not miss this trend of change, as the political bankruptcy of the state apparatus led to weak independence, and a huge corruption component exhausted the economy and brought Ukraine to the brink of economic crisis. The decisive way to solve this problem was the renewal of the public procurement system, governed by specific regulations, and its transfer from the shadow format to the electronic one in 2016 for public availability. An e-procurement system is a tool for detecting and combating corruption through numerous tools for monitoring and analyzing public procurement. In addition, the system is unique in its structure, since it works in cooperation with three parties – government, business, and the public. Purpose. The purpose of the article is to study and compare the laws of Ukraine "On public procurement" that were in force until 2021 and the new law that came into force on 01.01.2021. Fundamental amending and supplementing to the articles of the law are subject to assessment. Results. The issue of current innovations in the public procurement sector is investigated. The historical development of the implementation of the public procurement system on the example of "Prozzoro" is highlighted. The paper deals with the cycle and the process of implementation of public procurement, the structure of the electronic system of public procurement. The general state of functioning of electronic procurement in Ukraine and tools of the e-procurement analytics module is analyzed. Public procurement procedures contribute to the provision of society with goods, works, and services in the required quantity and quality on time and acceptable contractual relations. It is difficult to imagine the development of economic prosperity without the full functioning of the mechanism of transparent public procurement, which can ensure uninterrupted interaction between all representatives of the economic system at the macroeconomic level. The Law of Ukraine "On Public Procurement" and some other legislative acts of Ukraine on strengthening control and responsibility for violations of legislation in the field of public procurement, ensuring proper protection of the rights of public procurement participants are analyzed. The prospect of further research is to consider the content and evaluation of innovations in the Law of Ukraine "On Public Procurement" and objective conclusions regarding innovative solutions and future developments. Conclusions. The most significant achievements in the development of the public procurement system in Ukraine were achieved in the period 2016-2021 since the enactment of the Law of Ukraine "On Public Procurement" and the introduction of the electronic procurement system ProZorro. To this date, the achievements in the field of reforming the public procurement system are noticeable to the general public, because the disclosure of the system has increased the level of knowledge of citizens in this area. However, there are gaps in the legislation that do not exclude the possibility of abuse by individual bidders. This necessitates further scientific research towards the development of the public procurement system in Ukraine. The prospect of further research is to consider the content and evaluation of innovations in the Law of Ukraine "On Public Procurement" and objective conclusions regarding innovative solutions and future developments.

Subject. The article deals with the analysis of suppliers in the public procurement system based on reasonable prequalification parameters. Objectives. The aim is to test the hypothesis about strong reputation characteristics of the winners in the public procurement system and develop a methodology for assessing the reputation of suppliers for prequalification purposes. Methods. We employ general scientific principles and methods of research, like abstraction, generalization of approaches used by domestic and foreign authors for prequalification and assessment of reputation of public procurement participants. Results. To test the hypothesis, we calculated four groups of indicators on corporate, financial, market, and social components of reputation. The methodology was tested on the data obtained from SPARK-Interfax and SPARK-Marketing information resources. Conclusions. The study revealed that not all reputational characteristics of public procurement winners can be regarded as high level. In terms of the corporate component, it is the low level of share capital, indicating the mistrust on the part of owners and their reluctance to invest in the business, and the low percentage of non-current assets. In terms of the market component, it is a low sales growth rate, as well as low return on sales. As to the financial component, it is a low capitalization of winners, low share of long-term debt capital and low credit limit. With respect to the social component, it is a below-average tax burden.

Finger Tapping Test

The paper considers the method for analysis of a psychophysical state of a person on psychomotor indicators – finger tapping test. The app for mobile phone that generalizes the classic tapping test is developed for experiments. Developed tool allows collecting samples and analyzing them like individual experiments and like dataset as a whole. The data based on statistical methods and optimization of hyperparameters is investigated for anomalies, and an algorithm for reducing their number is developed. The machine learning model is used to predict different features of the dataset. These experiments demonstrate the data structure obtained using finger tapping test. As a result, we gained knowledge of how to conduct experiments for better generalization of the model in future. A method for removing anomalies is developed and it can be used in further research to increase an accuracy of the model. Developed model is a multilayer recurrent neural network that works well with the classification of time series. Error of model learning on a synthetic dataset is 1.5% and on a real data from similar distribution is 5%.
