The research identifies the priority of the improvement in Boards of Directors in the Russian power companies to enhance their corporate governance in the interests of investors. This is caused by numerous inconsistencies between the responsibility in the framework of the Boards of Directors in the current corporate practice and the principles and recommendations of the Code of Corporate Governance...
With the ongoing demand for improved K-12 STEM education, a push for dual-credit courses, and the goal of college and career-ready high school graduates, schools have implemented numerous STEM programs including those focused on engineering. Curricular programs, such Engineering by Design, Project Lead the Way (PLTW), and EPICS High are being executed by schools across the country with varied amounts...
The paper studies a practical problem of resource assignment and optimal human resource allocation scheduling with the objective of minimizing employees' useless working time and retire some workers. We analyze simultaneous employment staff with different competencies (skills) that needed to complete jobs. Each job and worker have a set of individual parameters. The mathematical model of assignment...
Over the past three decades, plenty of techniques have been developed to solve cell formation problems. However, most researchers focus on forming cells in a single run or non-incrementally without considering implementation, planning and capital investment issues. This paper proposes a mixed-integer goal programming model to deal with incremental cell formation problem, in which human factor is involved...
This paper presents methods solving MS-RCPSP as a main task-resource-time assignment optimization problem. In the paper there are presented four variants of Evolutionary Algorithm applied to MS-RCPSP problem: concerning prioritization the tasks (or resources), combined task-resources prioritizing approach and co-evolution based approach that effectively solves problem dividing it to two subproblems...
This paper deals with the “Clean Energy for All Europeans” proposals presented by the European Commission on Wednesday, 30th November 2016 in its constant endeavor to mobilize efforts of the innovation community and lead the transition toward a more decentralized, decarbonized, democratized, diversified, digitalized and disruptive model.
The paper is dedicated to the development of modern education technologies in distinct regions on the example of Yamalo-Nenets Autonomous Okrug. The author showed that students in this region are underprivileged besides the level of average income and salary because of a lack of ordinary higher education programs and low Internet quality. The development of e-learning opportunities can increase quality...
Online professional social networks such as LinkedIn have enhanced the ability of job seekers to discover and assess career opportunities, and the ability of job providers to discover and assess potential candidates. For most job seekers, salary (or broadly compensation) is a crucial consideration in choosing a new job. At the same time, job seekers face challenges in learning the compensation associated...
Spreadsheets often contain faults that are difficult to localize. Spectrum-based Fault Localization (SFL) assists users in the fault localization process by ranking cells by their suspiciousness to contain a fault. Since the ranking of the basic SFL approach is often imprecise, we propose three techniques to improve it, i.e., dynamic cones, grouping, and tie-breaking. We evaluate these techniques...
Passengers and freight mobility in urban areas represents an increasingly relevant component of modern city life. On one side, it fosters economic growth, but, on the other, it also generates high social costs. Congestion and pollution are two problems policy-makers want to curb adopting appropriate measures. The pervasive use of information and communication technology will contribute to the fuller...
Compared to living alone, sharing housing with others is usually much cheaper. Meanwhile, share-housing life would exert mammoth impact on people's social activity and self development by help them save house rental cost and improve their life quality. This paper proposes an allocation information system for share-housing management, which takes into account preference on roommates' living habits,...
A Distribution System Operator (DSO) might consider a capacity contract as a planning alternative to defer grid investments. A Virtual Power Plant (VPP) might be able to provide such capacity and change its production as requested by the DSO. This article presents an assessment of the impact of this type of distribution capacity contract (DCC) on VPP's remuneration. This assessment is done by comparing...
Electricity market design varies across countries throughout Europe. Thereby the provision and remuneration of flexibility always takes place in short-term market segments. Taking into consideration the fundamental changes of the power system, this paper discusses options for the future short-term market design. We develop a conceptual basis for a possible integration of currently separated short-term...
The aim of this paper is to study the implications of the decision of the French regulator to join the FCR Cooperation, a common platform for cross-border procurement of primary reserve. Two aspects will be analyzed: 1) cost of procurement and increase of social welfare by cross-border procurement and 2) implications for entry of new entrants like aggregators of Electric Vehicles. Our results are...
The first part of the article presents the assumptions of the capacity market in Poland that was recently presented by the Ministry of Economy. The mechanism is based on the centralized capacity market solution already implemented in Great Britain, however, introduces novel solutions such as separate auctions for new and existing power units. In the second part, we described the modifications that...
The increase of distributed energy resources in energy systems and current legislation concerning the participation in energy markets, is causing a high wasted potential of energy supply and flexibility services. In this paper, it is proposed a methodology for the management and integration of distributed energy resources in energy systems and markets, through the application of an aggregator. Also,...
The analysis of the human migration process has been studied in various fields of science. This work, focuses on migration indicators proposed by the International Migration Policy, with the aim of identifying the most important indicator from the point of view of data mining. This study identifies migrant stock as the most important factor related to the values obtained by the F1Score and the ROC...
Using the case of organization H, this paper studies the current development of scientific and technological talents. Based on recent research in this filed, we develop an index system of incentive factors, including material incentive, implicit incentive, support incentive and growth incentive. Then we survey 244 scientific and technological talents and use factor analysis method to study the valid...
One of our goals is to formalize an equivalence class(FEC) of the fuzzy relational database(FRDB). FRDB, an extension of RDB using a soft computing technique, fuzzy theory. Using our relational formulas of relational calculus, we can denote its properties by simple and correct formulas. Also, we can prove its properties formally using relational calculus. There are many applications of FRDB such as...
Offshoring software development activities to a remote site in another country continues to be one of the key strategies to save development cost. However, the assumed economic benefits of offshoring are often questionable, due to a large number of hidden costs and too simple cost calculations. This study is a continuation of our work on calculating the true hourly cost that includes the extra direct...
