A brief conceptual description of the algorithm for the development of internal audit support systems is given, with a statement of the main difficulties in the selection of components. The development of an intelligent internal audit support system is an important and necessary task, as internal audit plays an important role in ensuring effective management and control of a business entity. An intelligent system can help increase the efficiency of audit processes and provide more accurate results of automation and application of analytical tools. Over time, a business entity accumulates more and more data, and their analysis becomes an extremely difficult task. An intelligent system can quickly process large amounts of data, identify trends, anomalies, and risks that allow for more informed decisions; it can also identify unusual transactions or shortages that may indicate the possibility of fraud or error; it can provide auditors with valuable information and analytics to make informed decisions decisions on improving management processes and ensuring effective control mechanisms. This will help prevent the possibility of financial losses and preserve the reputation of the business entity. Consideration of some steps of the ISPVA algorithm is based on a brief comparative analysis of mathematical support methods.","PeriodicalId":321731,"journal":{"name":"Management of Development of Complex Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116804378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Determining such time characteristics of the system at the design stage is a rather difficult problem. Its solution is currently based on the use of two main methods: theoretical calculations related to the calculation of the so-called feasibility criteria and modeling of the system's operation on models. Among the models, statistical models of mass service systems are the most widespread. However, in both the first and second options, it is impossible to obtain a guaranteed result, which significantly complicates the design process. Recently, it has been proposed to use the methods of researching models based on the use of the Petri net apparatus. The paper proposes a method for estimating the time characteristics of tasks in real-time systems by means of data analysis. Obtained by modeling the distribution of processor time between tasks according to the selected algorithms of the scheduler by using a model of the software system in the form of a Petri net. The paper proposes a method for estimating the time characteristics of tasks in real-time systems by means of data analysis. Obtained by modeling the distribution of processor time between tasks according to the selected algorithms of the scheduler by using a model of the software system in the form of a Petri net. The method guarantees obtaining the time characteristics of the tasks when choosing specific types of processor and scheduler, which is required to start the technical design of the real-time system. The use of the proposed mathematical model and a package of application programs allow, at the early stages of the development of a real-time system, to determine the real terms of tasks and choose the optimal option for the implementation of technical and lost support. The proposed mathematical models are based on determining the time characteristics of program execution by modeling the distribution of processor time between tasks, subject to the prior selection of planning algorithms and the characteristics of a complex of technical means. The research is based on the use of simulated statistical models and Petri net models, The use of the proposed tools allows you to significantly reduce the time of analysis of possible options for real-time system implementation, increases the quality of the project and significantly reduces the overall time and cost of the entire development. The paper examines in detail the process of modeling a multitasking computer system using a Petri net device. A concrete example shows the simulation of the operation of a complex of programs, including the development of simulation algorithms, the listing of the simulation program, and the analysis of the obtained results.","PeriodicalId":321731,"journal":{"name":"Management of Development of Complex Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127823302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have gained great popularity in recent years. The relevance of the application and evaluation of the effectiveness of CRM systems is considered, which is entirely determined by the modern needs of the company's business management based on such systems. It was determined that the evaluation of the effectiveness of CRM systems helps to evaluate the effectiveness of the use of the system and to make the necessary adjustments. The analysis of literary sources from the research of many scientists on the problems of evaluating the effectiveness of CRM systems was carried out. The feasibility of evaluating the effectiveness of CRM systems for the company is caused by the need for a comprehensive evaluation of the system's effectiveness from the point of view of its ability to improve customer service; increase customer loyalty; generate more sales; return on investment. The purpose of this work is to review the existing approaches to assessing the effectiveness of CRM systems. The need to apply the basic approaches to evaluate the effectiveness of CRM systems, which are studied in the work, is determined by the introduction of processes of automation, marketing, work with clients and data analysis. Each of them is used depending on the specific business needs of the company, its goals and has advantages and disadvantages. The authors present the features of methods for evaluating the effectiveness of CRM systems. It was determined that the analysis of indicators of client activity is one of the most powerful marketing tools for evaluating the effectiveness of CRM systems. It allows companies to adapt their products and services to the specific needs of customers and increase sales efficiency. Equally important and one of the most common approaches is the analysis of marketing effectiveness. It is useful for determining the effectiveness of marketing strategies and advertising companies used in the CRM system. The evaluation of the effectiveness of the CRM system using the analysis of the level of customer satisfaction is described in detail. It is determined that the marketing research of consumer satisfaction for the company is based on several main performance indicators: CSAT, NPS, CES. Performance analysis is presented, which allows you to evaluate the effectiveness of the CRM system by comparing the performance of personnel before and after using the system. The analysis of technical support and resources is considered - relevant and necessary for any company that works with technology.

The main attention in the analysis is paid to the practical application of de Broglie waves in systems of interacting particles. For this purpose, Bohr's theory of the hydrogen atom has been revised and inconsistencies that contradict modern ideas have been corrected. Two conclusions are made: wave representations of particles are of a material nature; the de Broglie wavelength should be determined in terms of the relative momentum of the interacting particles . Based on the materiality of wave representations, the features of the long-wave interaction of particles are determined. It is emphasized that in many manifestations this interaction has a resonant character. This interaction is the foundation for the universal mechanism for the development of self-ordering processes in systems of identical particles. The paper presents an algorithm for the emergence and functioning of a universal mechanism. The condition for the emergence is always any withdrawal of the system from the state of isotropic chaos and the formation of an initial subgroup of particles with the same magnitude and direction of momenta. The most common cause leading to the fulfillment of the condition is monoenergization of the spectrum of particles in the system. The causative agent of the mechanism is direct collisions of particles, in which the probability of long-wavelength representations is the highest. The development of the mechanism is limited only by the fulfillment of the percolation condition - overcoming the percolation threshold. The final stage of the mechanism is the formation of a superfluid component - a kind of macroparticle that does not interact with walls and other molecules. A characteristic wave feature of such a macroparticle is its coherence. Several final stages in the development of self-ordering processes for typical special phenomena in systems of identical particles are analyzed.","PeriodicalId":321731,"journal":{"name":"Management of Development of Complex Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132486770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, multispectral images produces a very\u0000 large volume of data. Processing the huge volume of information is one of most important\u0000 and actual problems of remote sensing. The rapid development of the  remote sensing\u0000 demand to develop the data processing algorithms. But at present data processing\u0000 techniques cannot give accurate results. If  we use traditional methods to process\u0000 multispectral images, the volume of  the data increases. The main goal of the band\u0000 selection is to choose the optimal combination of  spectral bands for the solution of\u0000 the particular remote sensing task. This process is important because different bands\u0000 are sensitive to different objects. Selecting the right bands can help to optimize the\u0000 detection of different ground objects. Some spectral bands are more sensitive to\u0000 minerals, while others are more sensitive to vegetation  or water bodies. Under a small\u0000 number of training samples, the classification accuracy of multispectral images\u0000 decreases when the volume of multispectral data increases.

Humanity has no activity\u0000 other than organizational, there are no tasks other than organizational. Therefore, all\u0000 interests of humanity are organizational. And from this it follows: there cannot and\u0000 should not be another point of view on life and the world, except for the organizational\u0000 one.

It is also not accidental that a person\u0000 should learn from Nature and the Higher Mind, because the systems created by Nature (for\u0000 example, families of organized animals) are far superior in their perfection to the\u0000 systems created by man. The genome of perfection is a natural creation, and man still\u0000 needs to work a lot on himself to achieve even known systems created by Nature, not to\u0000 mention supra-conceptual management and activity at levels higher than the human level\u0000 of mind at this stage of human development.

The improvement\u0000 of organizations will continue without end as long as humanity exists, because there are\u0000 no limits to perfection.
