Research background: Project portfolio optimization isa  demanding process in the case of considering a large number of project intentions and has so far been the subject of research by many authors, especially foreign authors. However, the issue of project portfolio optimization is an area that is not sufficiently addressed by Slovak authors. This was the main impulse to create a specific mathematical model of integer programming with bivalent variables to optimize the company's project portfolio with the intention to reflect the specific requirements of Slovak companies. Purpose of the article: The aim of the article is to propose a mathematical model of integer programming with bivalent variables to optimize the project portfolio with a focus on Slovak companies. Methods: In accordance with the aim of the article, a questionnaire survey was carried out with the intention of identifying the criteria that are perceived by the managers of Slovak companies as important in the optimization of the project portfolio. These criteria were subsequently reflected in the mathematical model design using the mathematical programming method. Findings & Value added: Based on a literature review aimed at the project portfolio optimization, we have found a gap in considering the compliance of project intentions and strategic objectives of the company within the optimization of the project portfolio. Based on the results of the questionnaire survey, the significance of the mutual compliance of project intentions with the strategic objectives of the company was confirmed from the point of view of Slovak companies. Given the fact that our aim was to create an innovative integer programming model with bivalent variables orientated to the conditions of Slovak companies, we included in the resulting model the criteria that were not considered within the scope of existing research in this area, and which are perceived as important by the Slovak companies.

The goal of the work was to identify research and compare methods of portfolio management of energy saving projects and to develop software for optimizing portfolio investments using several methods. The key elements and strategies of creating an effective investment portfolio are considered: diversification, rebalancing, active portfolio management, passive portfolio management. Given the basic principles of investment theory, the task of portfolio investment is to form an investment portfolio with known shares of certain assets to maximize returns and minimize risk. To solve this problem, the method of Harry Markowitz, known as modern portfolio theory, was chosen. This is the theory of financial investment, in which statistical methods are used to make the most profitable risk distribution of the securities portfolio and income valuation, its components are asset valuation, investment decisions, portfolio optimization, evaluation of results. From a mathematical point of view, the problem of forming an optimal portfolio is the problem of optimizing a quadratic function (finding the minimum) with linear constraints on the arguments of the function. Methods of optimization of portfolios of energy saving projects taking into account the specifics of the subject area are analyzed. According to the results of the analysis, the methods of finding the maximum Sharpe’s ratio and the minimum volatility from randomly generated portfolios were chosen. A software application has been developed that allows you to download data, generate random portfolios and optimize them with selected methods. A graphical display of portfolio optimization results has also been implemented. The program was tested on data on shares of energy saving companies. The graphs built by the program allow the operator to better assess the created portfolio of the energy saving project.

Project Portfolio Management is a relatively new practice for the majority of non-government organisations. Project portfolio management is important in the areas of management and education of third sector practitioners. However, project portfolio management, corporate management tools are usually used in the business sector with very little research undertaken in the non-government sectors. This chapter fills that research gap by identifying and analysis of project portfolio management practices in non-governmental organizations. Findings suggest that non-government organisations manage multiple projects simultaneously but that project portfolio management could support them to build their portfolio in accordance with a strategic plan that can fulfil their strategic objectives efficiently and effectively.

Continuous Demand

Demand Management is the process an organization puts in place to internally collect new ideas, projects and needs during the creation of a Portfolio (from now on PTF). This collection is done internally but should also consider the external market situation and the general Strategy of the Organization. Demand contains two main actions: initiatives Collection and Assessment (following the Strategic Objectives definition) and preceding the start of the Portfolio budgeting, prioritization and selection phases. What is possible to do to better manage Demand and maximize the value added to Portfolio Management? The first opportunity is that Demand can represent a connection with the business and the entire Organization. A second opportunity is that a continuous Demand Management approach can simplify the portfolio collection, prioritization and selection. For Demand Management to be a real opportunity in Portfolio Management should be organized and planned respecting the interpretation of the matter and the maturity of the Organisation and should be also treated as a specific matter.

Decision Making Model

Reviewed the research status of portfolio decision-making at home and abroad; On the background of project portfolio management theory, a large number of the current model of portfolio decision-making were researched. From the perspective of project managers, Taking work breakdown structure(WBS) as the basis and combining with portfolio management systems and 0-1 programming model , expanded 0-1 programming project quantitative portfolio model was proposed. This model will provide a reference for the research of project quantitative portfolio decision-making.

The Mathematical Model

In any organization all its processes are interrelated to achieve its strategic objectives. The purpose of this study is to propose a goal programming model for the optimization of the objectives of the maintenance area. Linear programming is a mathematical technique that allows the optimization of processes by analysing the variables involved in them through mathematical algorithms. The first stage is the formulation of the mathematical model characterized by the indicators of the maintenance area and the strategic objectives, the second stage is the solution of the mathematical model of goal programming considering different scenarios. The last stage is the validation by experts of the maintenance area before implementing it in the organizations. The expected benefit is that it is a tool for decision making in the maintenance area to consider that your activities can be optimized either to increase your benefits and / or decrease your costs through the technique of goal programming.
