In some cases, a medium range optimization problem is also defined. Operation scheduling for nuclear-hydro-thermal power systems is a typical example. The above represents an intuitive description of a possible hierarchical decomposition of the operation scheduling problem. In this paper we present a mathematical treatment in terms of a controlled finite state Markov process. Our treatment indicates how the approximate decomposition of the time scale and the aggregation of the state space follows from properties of the probability transition matrix of the Markov process.","PeriodicalId":338908,"journal":{"name":"1979 18th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129210742","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}

Willsky","doi":"10.1109/CDC.1979.270268","DOIUrl":"https://doi.org/10.1109/CDC.1979.270268","url":null,"abstract":"This paper formulates a general optimal stopping problem for random fields with a partially ordered parameter set and with a partially ordered information structure in the sense of Ho and Chu [1]. It is possible in this framework of partially ordered parameters to formulate naturally a wide variety of stopping problems which are difficult or impossible to formulate in the conventional one-parameter framework. The dynamic programming solution of the one-parameter stopping problem extends to the more general case of partially ordered parameters. The resulting dynamic program is backward recursive with respect to the partial order, and this recursive property enables one to use the full structure of the partially ordered parameter set to calculate the solution to the stopping problem in an efficient manner.","PeriodicalId":338908,"journal":{"name":"1979 18th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121372499","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}

At the same time, new devices based on technically sophisticated microelectronics seem to promise easy solutions to communications and control problems. Manufacturers of this type of equipment are eager to meet the large potential market with technological solutions but as yet the cost effectiveness of such solutions has not been demonstrated. The Department of Energy/Electric Power Research Institute (DOE/EPRI) sponsored Field Demonstration of Communication Systems for Distribution Automation, along with several (smaller) utility field trials are revealing much about the effectiveness of various types of communicatons systems, for load management and distribution automation and also about the problems of installation and customer acceptance. The five DOE/EPRI field demonstrations1 are in various stages of analysis and operation. One of the demonstrations, based on telephone communication2, completed the one year data acquistion period, July 31, 1979, and analysis for the final report is now in progress. Three different power-line carrier systems started the one year data acquisition period on July 1, 1979. The radio system is scheduled to start the one year data acquisition in September 1979.","PeriodicalId":338908,"journal":{"name":"1979 18th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126940254","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}

In this paper attention is called to the fact that it is also a very useful tool for computing and evaluating affine approximations of multi-dimensional nonlinear maps over specified domains. Included are preliminary ideas about application of the tool to the following problems: numerical linearization of dynamic systems, gradient approximations for optimization, and numerical differentiation of vector time signals.","PeriodicalId":338908,"journal":{"name":"1979 18th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114814061","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}

These constraints define a class of matrices, and unless it has a unique member, one is faced with computing a \"good\" feedback matrix. In this paper we address two aspects of this problem which allow direct application of numerical analysis work. Essentially, there are two ideas which are discussed 1) If the closed loop eigenvalues are separated, one should avoid a closed loop system whose eigenvector matrix is nearly singular. 2) If there are to be repeated or clustered eigenvalues, one should not deal directly with the eigenvectors of the cluster; instead one should use an orthogonal basis which approximates the corresponding closed loop (A+BF) invariant subspace.","PeriodicalId":338908,"journal":{"name":"1979 18th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1979-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114985764","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}
