A manager facing the decision whether to proceed with a proposed computer system development project needs to determine whether its benefits are worth more than its costs. This can be done by applying a simple mathematical formula to calculate the project's 'net worth', as the sum of the annual benefits obtainable during the system's life span, less its development costs. The formula recognizes that a system's annual benefit, comprising enhanced informational value plus reduction In data processing cost, will change as a result of obsolescence, cost of capital, organizational growth and learning.

The main disadvantages of the existing methods of managing the current state of technical systems are revealed. A non-standard approach is proposed for managing the functionality of the system in emergency situations. The character of the dynamics of the recovery processes of the technical system is determined as its state approaches the emergency one on the basis of the recommendations of the theory of self-organized criticality (SOC). The physical criteria for assessing the current state of the technical system are revealed. The rationale for using the physical indicator of the functional destabilization of the system is given. The signs of the pre-emergency state of the technical system are considered. A grapho-analytical model for the development of an emergency situation has been developed. The fact of the inevitable increase in the entropy of the system upon its transition to an emergency state is established. Structuring of the system development process in an emergency situation is carried out in three stages. The methodology for estimating the pre-emergency state of complex open systems is presented. The advantages of the proposed approach to managing the state of technical systems in comparison with traditional ones are established.

How do firms create and capture value in large technical systems? In this paper, I argue that the points of both value creation and value capture are the system’s bottlenecks. Bottlenecks arise first as important technical problems to be solved. Once the problem is solved, Then the solution in combination with organizational boundaries and property rights can be used to capture a stream of rents. The tools a firm can use to manage bottlenecks are, first, an understanding first of the technical architecture of the system; and, second, an understanding of the industry architecture in which the technical system is embedded. Although these tools involve disparate bodies of knowledge, they must be used in tandem to achieve maximum effect. Dynamic architectural capabilities provide managers with the ability to see a complex technical system in an abstract way and change the system’s structure to manage bottlenecks and modules in conjunction with the firm’s organizational boundaries and property rights.

In the proposed article, various methods of constructing an artificial neural network as one of the components of a hybrid expert system for diagnosis were investigated. A review of foreign literature in recent years was conducted, where hybrid expert systems were considered as an integral part of complex technical systems in the field of security. The advantages and disadvantages of artificial neural networks are listed, and the main problems in creating hybrid expert systems for diagnostics are indicated, proving the relevance of further development of artificial neural networks for hybrid expert systems. The approaches to the analysis of natural language sentences, which are used for the work of hybrid expert systems with artificial neural networks, are considered. A bulletin board is shown, its structure and principle of operation are described. The structure of the bulletin board is divided into levels and sublevels. At sublevels, a confidence factor is applied. The dependence of the values of the confidence factor on the fulfillment of a particular condition is shown. The links between the levels and sublevels of the bulletin board are also described. As an artificial neural network architecture, the «key-threshold» model is used, the rule of neuron operation is shown. In addition, an artificial neural network has the property of training, based on the application of the penalty property, which is able to calculate depending on the accident situation. The behavior of a complex technical system, as well as its faulty states, are modeled using a model that describes the structure and behavior of a given system. To optimize the data of a complex technical system, an evolutionary algorithm is used to minimize the objective function. Solutions to the optimization problem consist of Pareto solution vectors. Optimization and training tasks are solved by using the Hopfield network. In general, a hybrid expert system is described using semantic networks, which consist of vertices and edges. The reference model of a complex technical system is stored in the knowledge base and updated during the acquisition of new knowledge. In an emergency, or about its premise, with the help of neural networks, a search is made for the cause and the control action necessary to eliminate the accident. The considered approaches, interacting with each other, can improve the operation of diagnostic artificial neural networks in the case of emergency management, showing more accurate data in a short time. In addition, the use of such a network for analyzing the state of health, as well as forecasting based on diagnostic data using the example of a complex technical system, is presented.

The relevance of the communication in the complex information system (IS) development projects is becoming issue of primary importance. Various researches show that many projects failed due to inadequate management of communication. Project data exchange is still not performed in a structured and standardised manner, which leads to misunderstandings between team members. Too many complex IS projects do not have established an adequate project communication management subsystems. This paper analyses results of a survey performed on information technology (IT) professionals and presents degree of communication problems during various project phases. (This research was supported by the Croatian Ministry of Science and Technology under projects: "Strategic planning of Information Systems" and "Information Systems Security.) It reveals that average rating of a degree of communication problems varies at different project stages and among different communication subjects. The paper also proposes software tools that, if properly used, might enhance project communication. Such technologies are still not completely mature but they are developing fast and might play an important role in project management, by providing support to its holism.

Crowdfunding as a tool for alternative financing has emerged relatively recently and is of limited use in Ukraine today. At the same time, it has significant potential, which can contribute to the implementation of a wide range of projects that for various reasons are not of interest to traditional lenders or investors. The aim of the article is to determine the benefits of crowdfunding for its participants, the peculiarities of the implementation of certain types of crowdfunding and identify risks that may be generated by them, as well as develop practical recommendations for crowdfunding campaigns by entrepreneurs and authors of community development projects. The article identifies the benefits of crowdfunding for project authors (low cost of capital, access to information and potential investors) and investors (clarity, low risks, access to new products, the ability to support creative ideas), substantiates the role of crowdfunding platforms in realizing the benefits of crowdfunding. The advantages and disadvantages of using certain types of crowdfunding are described. Recommendations for planning and implementation of the main stages of crowdfunding campaigns - idea development, target audience determination, research, communication, project budgeting, reward system development, campaign schedule development – are developed. The factors of choosing a crowdfunding platform for hosting the project are determined. The possibility of using crowdfunding for collective financing of socio-cultural projects within the public budgets of the united territorial communities is shown. The risks of using crowdfunding for project authors and potential investors are identified. Those risks are primarily related to realistic expectations and proper preparation for the fundraising campaign by project authors, as well as the lack of guarantees for investors in the event of problems or bankruptcy of the crowdfunding platform. The author highlights that the growth of public awareness about the possibilities of implementing social or business initiatives through crowdfunding platforms will contribute to the development of platforms, improvement of technological equipment, and expansion of their range of services.
