Differential Privacy: An Economic Method for Choosing Epsilon

This article summarizes the concept of sharing, bibliographic analysis of publications in the field of car-sharing based on the Scopus database. The primary purpose of the study is to study the economic and legal basis for the development of car-sharing business models in Ukraine. Systematization of literature sources and approaches devoted to the economic efficiency of the implementation of car-sharing business models has shown that in Ukraine, this issue is almost not paid attention to in the economic, scientific sphere, and legal, scientific areas. The urgency of solving this scientific problem lies in the need and ability to relieve road traffic from traffic jams, reducing the average downtime of vehicles, as well as economic benefits for entities (vehicle owners and passengers) involved in sharing business models. The research has the following logical sequence: the types of car-sharing business models were analyzed, and their comparative characteristics were carried out; the economic and legal preconditions of car-sharing business development in Ukraine are investigated. The research identifies legislative obstacles to the establishment of a car-sharing company in Ukraine. A SWOT analysis of the conditions for implementing a car-sharing business model in Ukraine was performed. It analyses the costs and efficiency of creating a business based on a car-sharing business model in Ukraine on a conditional example. We propose to use system-structural and comparative analysis to analyze the problems of modern transport, methods of formal-logical analysis for determining the directions of development of car-sharing business models, and economic method for assessing the effect and a payback period of the proposed project car-sharing business model. The study results can be useful for the development of the car-sharing business in Ukraine, for entrepreneurs, scientists, and vehicle owners. Keywords: car-sharing, car-sharing business model, car-sharing business, motor transport, hire, expenses, analysis.

Supply Reliability

During the functioning of power supply system, there can be situations where the culprit in interruptions of power supply to consumers and a power quality violation is a power supply company or a consumer himself. Therefore, the economic incentive for power supply companies and consumers to increase power supply reliability and power quality is an urgent task. To implement such incentives, it is necessary to control the facts and time of power supply outages and their values as well as cases and time of non-compliance of power quality with the requirements of standards. It is possible with the use of a monitoring system for power supply reliability and power quality. (Research purpose) The research purpose is in developing a technical and economic method for stimulating power supply companies and consumers to increase efficiency of power supply system. (Materials and methods) The article provides a review of the structural diagram of a system for monitoring power supply reliability and power quality including devices for monitoring the number and duration of power outages and voltage deviations. (Results and discussion). An economic method has been developed to stimulate power supply companies and consumers to increase power supply system efficiency. The essence of the method is to control the parameters of power supply reliability and power quality, identify the violation of these parameters, determine the culprit of the violation, determine the time characteristics of the violation, summarize the duration of violations for the reporting period, compare the actual amount of duration with the allowable one, determine the amount of compensation for the violation and impose sanctions on payment compensation by the perpetrators of violations of these parameters. The article presents an algorithm for adjusting the cost of electricity supplied to consumers depending on the number and duration of voltage deviations and the number and duration of outages. The algorithm serves to ensure the operation of the specified technical and economic method. (Conclusions) The algorithm works in conjunction with a system for monitoring power supply reliability and power quality based on signals from devices that control the number and duration of outages and voltage deviations.
