In the framework of the current system of maintenance and repair of petroleum reservoirs to develop a method for constructing effective schedules for the technical diagnostics of these structures during operation Raising of problem . The content and frequency of technical diagnostics of petroleum reservoirs (RVS) are regulated by the current regulatory documents. However, from the point of view of economic efficiency, the relevant questions with regard to the particular reservoir (or reservoirs park) under the conditions of a particular petroleum depot require further investigation. Such a situation, which has developed in the practice of audits of the technical condition of RVS in service in Ukraine, requires the development of new mathematical models and methods that adequately reflect the essence of the problem of effective management of operational reliability of the facilities in question. Methodology .The article proposes a model of management of operational reliability of RVS based on the minimum of total operating costs, which is formulated in terms of the problem of nonlinear mathematical programming with binary variables. For the numerical realization of this model, a special algorithm based on the principles of constructing \"greedy\" algorithms was developed, using which economically rational intervals for carrying out technical inspections of the reservoir with a volume of 5000 m 3 , depending on the required level of operational reliability.. Conclusions. The proposed optimization model for managing the operational reliability of petroleum reservoirs makes it possible to form economically rational strategies for auditing their technical condition over a given service life. This model can be useful in the practice of planning revisions of the technical condition of the RVS both at the initial and at any other stage of the operation process. In addition, this model can be used in reliability problems both for individual reservoir and parks of such reservoirs.","PeriodicalId":401403,"journal":{"name":"Construction, materials science, mechanical engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126500333","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}

The purpose of this research was the evaluation of measurement accuracy for image motion in CCD matrix plane while creating a testing technology for thermal stability of technical products made of the carbon fiber reinforced plastic. Methodology. Mathematical modeling methods and digital image analysis (using MATLAB) have been used during the research. The magnitude of the image shear is suggested to be determined from the shift of the reference mark geometric center. Mathematic model of the laser spot digital image is used as a reference mark. Findings . Modeling technique for sub-pixel shear of a laser spot has been developed. Accuracy estimation of the image shear determination was made during the experiment. Impact of the change in the number of luminance quantization levels by preliminary processing of the original image was investigated for evaluation measurement sensitivity. The correspondence between the informative parameters of the technical image and the parameters characterizing the sub-pixel image shift has been confirmed. Originality of this study is the admission of the problem in controlling the thermostability of products made of carbon reinforced polymer composite materials by measuring the shear of digital images and investigating the effect of image recording conditions on the sensitivity and accuracy of measurements. Modeling techniques confirmed possibility of determining an image shear with sub-pixel accuracy using CCD matrix. Practical value . The solution of this problem will allow creating new measurement technologies for the input control of parts made of carbon reinforced plastic materials with a low coefficient of thermal expansion. Thus, it becomes possible as an output control of large-sized products thermostability, as well as monitoring the dimensional stability of products under operating conditions, including varying humidity conditions. The practical area of this results would be technical vision systems, aerospace technical facilities monitoring, particularly telescopes, truss structures and space-based antennas made of materials with a low coefficient of thermal expansion, as well as the design of digital autocollimators.","PeriodicalId":401403,"journal":{"name":"Construction, materials science, mechanical engineering","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133368581","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}
