The purpose of the system is to make current adequate decisions on determining of oil-and-gas saturation of strata and future identification of the most significant methods for that, with these methods forming the foundation of knowledge bases for oil-and-gas deposits of the Apsheron peninsula of Azerbaijan. The system architecture allows for expanding the system with its subsequent transformation into a cluster of expert-analytical systems. A logical model of the proposed system is presented. The paper contains a detailed description of the mechanism of operation of the system as a whole and of its individual blocks. Mathematical and formal-logical bases of the intelligent system are explained. The system is equipped with a tool for dynamic statistical analysis of decisions made by it, with representation of the results in real-time mode. The results of the system testing on specific oil-and-gas deposit of the Apsheron peninsula of Azerbaijan in 2013 are given.","PeriodicalId":62904,"journal":{"name":"智能控制与自动化(英文)","volume":"05 1","pages":"224-232"},"PeriodicalIF":0.0,"publicationDate":"2014-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70623045","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}

A technique of order preference by similarity to ideal solition (TOPSIS), was applied for evaluation and regulation of alternatives. This technique is based on criteria of qualitative character, which are hierarchically structured by multiple experts to intellectually support decisions made in personnel selection problem. Using TOPSIS method and generated criteria system an experiment was conducted for evaluation of the candidates during solution of hiring problems.

It is established by defining three new function sets and \u0000citing two function sets to construct three kinds of general bounded integral \u0000control actions and integrators, resorting to a universal strategy to transform \u0000ordinary control into general integral control and adopting Lyapunov method to \u0000analyze the stability of the closed-loop system. A universal theorem to ensure regionally \u0000as well as semi-globally asymptotic stability is provided in terms of some \u0000bounded information, and even does not need exact knowledge of Lyapunov \u0000function. Its one feature is that the indispensable element used to construct \u0000the general integrator can be taken as any integrable function, which satisfies \u0000Lipschitz condition and the self excited integral dynamic is asymptotically \u0000stable. Another feature is that the method to construct general bounded \u0000integral control action is extended to a wider function set. Based on this \u0000method, the control engineers not only can choose the most appropriate control \u0000law in hand but also have more freedom to construct the bounded integral \u0000control actions and integrators, and then a high performance integral \u0000controller is more easily found. As a result, the generalization of the bounded \u0000integral control is achieved.","PeriodicalId":62904,"journal":{"name":"智能控制与自动化(英文)","volume":"2014 1","pages":"146-155"},"PeriodicalIF":0.0,"publicationDate":"2014-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70623293","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}
