RECENT AND CURRENT RESEARCH
RESEARCH DIRECTED AND/OR PARTICIPATED IN
 
In the area of Probability Theory I have published works on:
 
A. Limit Theorems (Mostly related with my PhD Thesis):
- Application of Transfer theorems for random sums of random
variables in solving some limit problems of Renewal theory (uniform renewal limit theorems [11,12,17,105], in the study of transient behavior in Branching processes (with large number of ancestors) and special type of service systems (with fast service [6,10,13,18,22,23]). These works study conditions of the Gnedenko-Fahim theorem, or leading-term asymptotic expansion in the domain of attraction of the steady state of a process, to assess when to replace non-stationary characteristics by stationary ones, and how close the two are.
 
B. Probability Distributions (an old interest, and continuing research)
- Characterization of Probability Distributions and Stability
of Characterization problems, namely Exponential [45,49,60,71,75,79,93, 97,100], Poisson [89,90,105,109], the logistic distribution [105, and 111], and the introduction of the Almost lack of memory class of probability distributions [80,81,84,86,88,91,92,93,98,99,101,103,105,107,109,113,116], which has a broad impact on applications in environmental modeling, insurance business, financial mathematics and other fields.
C. Stochastic Processes of Special Type and Its Applications.
- Markov Chains and its applications in Probability Modeling. Here belongs the most of the power of Probability Modeling for Reliability, Queuing, Inventory problems, the new Markov Arrival Processes (invented recently by M. Neuts), and more. My book [3] is devoted to this techniques, and other books [1,2,6,11] are illustrating it. The Methods of Complementary event and complementary variable in combination, proposed and used in most of my works on priority queues are broadly based on the ideas of searching an underlying Markov process.
- Studies on Priority queues and Service with unreliable servers
Here belongs the monograph [1] on priority queues issued in 1973, Moscow University, in collaboration with coauthors B.Gnedenko, E.Danielyan, G.Klimov, and V.Matveev. Also the monograph [2], issued in Sofia, 1973 with A.Obretenov and E.Danielyan; the Handbook on Queues [4], 1978, which was translated into Polish in Poland [8], 1989. They reflect an extensive work on Priority Queues I did in my papers [2,5,6,8,9,10,13,14,15,16,18,21,22, 23,24,25,26,27,30,31,32,33,35,38], and more. As a main contribution here I consider the worked out Method of Complementary Events, which allows an interpretation of probability generating functions (the Laplace transform and the conventional generating function for discrete distributions), in combination with the Method of the Complementary Variables, broadly exploited in the cited monographs, and in most of the papers.
- Other Queuing Problems developed to study so called Closed Queuing Systems with Priorities (papers [10,14,26,27,30,]), Asymptotic Methods in Queues [22,23,35], Methods of Discretization [38,39,52,54,57,64], and various approaches to the Numerical Solutions for non-stationary process characteristics [34,36,38,39,48,54,56,64,65,68,74,101,103,111];
- Applications of Queuing Theory for Modeling Computational Systems and their Optimization in a non-reliable environment - were worked out mostly under contracts with Engineers of Bulgarian computer industry, 1976 - 1990, and used later as a source of other research projects. Here is my Doctorate on Mathematical Methods in Queuing Theory, acknowledged in 1986, most of the publications in the previous topics, and also in [34,36,40,41,42,48,51,63,66,70,78,82,101,104,111,117].
- Inventory systems - training, lecturing and supervising graduated projects for students in economics at Economical University of Sofia. Publications [10,21,44,47,59,67,72,85,96,112], and the textbook [6] are results of my work in this area. - Reliability studies - theoretical and practical works related to redundancy systems [2,3,4,6,7,11,19,117], statistical criterions for testing hypotheses in view of the specific information from reliability data [28,29,37,50,53,59,83,96]; optimization problems when work with non-reliable servers and other items were mentioned in the Applications of the Queuing Theory above. The new stuff essentially is concentrated on the introduction of models with check-points that may save execution time, the use of methods of discretization, the selection of specific statistical methods for standardized use, and the new point of view on reliability systems with random redundancy introduced in [91,117], important for communication systems and computer networks. The development of standardization documentation for practicing reliability and specialized computer packages for purposes of the Applied Statistics was actively made in years, and reflected in the papers [53,58,59,62,72,76,83,112]. In addition, most of my works in Statistics are related with the respective practical reliability problems [28,29,37,50,53,58,83].

 

    D. Warranty Analysis.
- Probability Models in Warranty Analysis (with Dr. S.Chukova), is an approach to incorporate the qualitative and quantitative marketing, technical and economical product characteristics in an integrated model and objective function to determine the optimal behavioral parameters of the corresponding models and processes in real world systems. It has been started by Grant 43 - 87 of Bulgarian Science Foundation, and still continues. The works in the field of reliability, noticed above, and the specific works in this field [77,89,90,94,108,110, plus the Dr. Chukova's works] brought us to the collaboration with world known experts like V. Rykov [94], W.Blischke and D.N.P.Murthy (BOOKS # 10, and [108]). Recently an unexpected relationship between warranty modeling and studies on probability distributions in periodic random environment is noticed [90,114,116], and promise good field of application for our class of Almost-Lack-of-Memory probability distributions. In this way, the processes used in warranties, and environmental and financial processes in the insurance mathematics will
be linked, and many problems may mutually gain from the solution for the others. The work continues in collaboration with colleagues and graduate students from Concordia University, Montreal on projects for Cost Analysis in Related Models.
 
E. Environmental Studies.
My interests on Environmental Probability and Statistical
Models and methods of their study were initiated. Modeling for
periodic random data related to water pollution and statistics
for parameters of Probability Distributions with Almost lack of memory property for Studying Environmental Properties, had proved fruitful in most of the work of myself and involved other colleagues. Here belong the most resent papers [88,90,92,98,103,105,107,109,114,115,116,117].

 

 
    Statistical Studies.
 
Related to Standardization, Applied Statistics, Reliability and Quality
- The work on Standards in Applied Statistics, Statistical Methods in Reliability and Quality Control brought to me a lot of practical experience (1975-1991). Being head of the Laboratory on Statistical Quality Control we developed International (for the former "East Countries"), and National (for Bulgaria) Standards as follows: Standards on Applied Statistics (e.g. Probability Distributions for Applied Statistics, Regression Analysis, Methods of comparing statistical samples), Standards on Reliability (e.g. Estimations of reliability characteristics, Terminology and Symbols, Design of experiments and testing, Tolerances and admissibility), Standards on Statistical Quality Control (SQC) (e.g. terminology and symbols, Statistical estimations of quality parameters of the outgoing production, Methods of statistical sampling from bulk products, Methods of statistical on-line control) and other documents related to the standardization. I wrote methodic (documentation) for practical implementation of the standardized mathematical methods, algorithmic and computational supervision for these methods. Computer programs for SQC, Reliability and Applied Statistics have been created in support of these practically directed works. My Ph.D. student Dimitar Christozov got his degree for the successfully developed program package RELIA-SOFT, where reliability characteristics are estimated from experimentally collected data, and/or field data for item performance. Also Grant #43 (1987-1991) with Bulgarian Science Foundation was awarded in relation to this subject, and involved more researchers in this work. Many of my publications in this field were related with the needs of specific standardization requirements, and with the statistical establishment when these requirements are met. These are the publications from the list [28,29,37,50,53,55,58,83 - for reliability], and [43,50,53,58,59,61,62,69,72,76,83,112 - for quality]. Among the papers related to reliability I would like to mention [50] and [55] where the statistical estimators proposed have the shape of the theoretical intensity function, as stated in the original problem.
- Studies on Statistical Optimization Problems under Incomplete Information [67,87,109]. This topic appeals to a resurrection of the known Markov-Tchebyshev moment problem in the construction of probability measures, and is one of the prospectives for research in the nearest future. Moreover, it has a clear connection with the construction of an Integral Indexes for the Quality of Products (started in [63] with M.Varbanova, I.Stefanov and L.Boneva and continuing be developed in [112]), Contract with INFORMA and the Laboratory of Statistical Quality Control initiated this work, but it is also a good field for further studies. The recent Wuerzburg Workshop (March '99) has shown the actuality and importance of this direction.
    
    IMPACT OF THE RESEARCH ON CURRICULA AND/OR STUDENTS
 
    Research related to my teaching.
University Textbooks combine teaching and research experience.
- After years of teaching and practicing Statistics I wrote the book Mathematical Statistics, 1982 (see BOOKS # 5) and the statistical part of the textbook Probability and Statistics for students of natural science at Bulgarian universities (see BOOKS, # 9, and # 12). Another textbook Statistics for non-mathematical students with an emphasize on statistical models and manipulations for non-numerical data is issued at Southwestern Bulgarian University in Blagoevgrad in 1993 (see BOOKS # 10). Also my teaching courses on Markov Processes at the University of Sofia for students in mathematics lead me to the book # 3, and the courses on Inventory Models and Quality Control for graduate students and post-graduate students at the University of Economics and World Economy in Sofia lead me to the writing of the books # 6 and # 7.
  Warranty models for technical items are field of my new interests too. The PhD thesis work of my former student, now colleague and wife, Dr. S. Chukova, the years of collaboration with her gave the result [Books # 11], which is useful for thesis work of graduate students in Engineering, and for select topic course too.
- Work on the Curriculum for university students is a collective work.
- While heading the Department of Probability and Statistics at the Faculty of Mathematics and Informatics at Sofia University (and 2 years as Dean of the Faculty) Computational Stochastics was added to the curricula for students and specialization at the Department was introduced. And it was result of the collective work of all members of the Department. Also curricula for other specializations in mathematics have been work out (Informatica, new specializations in Mechanics, Post-university education for high-school teachers), and this was result of the work of all departments and the work of the Faculty Senate.
High-school Textbooks  reflect some teaching experience and personal feeling of the need.
- Through my textbooks for high school students (listed under # 13-17), basic statistical aspects were introduced to high school students for the first time in Bulgaria.
Teaching and consulting Statistics, Modeling, or SQC at the University.
- During my first visits at Concordia University I taught Industrial Statistics and Quality Control, and worked under Contracts with the Center for Building Engineering, where I worked out methods for Statistical simulation of dependent random components in cost analysis problems (ref. to Dr. Z. Khalil, and Dr. Osama Moselhi, Tel. (514) 848-3190). Also a model for Statistical factor analysis of real data was explored. Add here my teaching experience with students of the specialization Probability and Statistics, the teaching of Quality Control, Reliability and Operations Research for students at the Division for Post-Universityy Education and Training of the Economical University of Sofia, my long term tenure as a head of the Laboratory on Statistical Quality Control, the work experience with International Standardization Organization, etc., and you'll understand what brought me to the idea to open The Statistics Clinic at Kettering University for free statistical consulting. It was open in the Fall of 1998 at the Science and Mathematics Department of Kettering University.
Here I work with computers and use almost any available statistical package in my Statistics Clinic, to serve as a consulting office for students, faculty and staff at Kettering University. It really gathers my experience in teaching, theoretical and practical work in years, and also offers (sometimes) new challenging problems to think on. Here also some software I developed for myself in collaboration with Dr. D. Christozov and other colleagues from Bulgaria is available to be demonstrated.

Impact on Curricula. The research with Thesis students and of my own has been used in the Laboratory work and Problem solving process in the class work. This is important for classes like Math-226 (Statistics for Management students, Part I), Math-227 (Statistics for Management students, Part II), and Math-408, Probability and Statistics for Engineers. The thesis advising process also is using the results and experience from the past.

        COLLABORATION WITH OTHERS
Within the Department
At the SM Department of Kettering University I enjoyed and continue the fruitful collaboration in almost all the areas of my research with Dr. Stefanka Chukova, in the area of Queuing and Production Modeling with Dr. Srinivas Chakravarthy, and in the area of Characterization by analytical means and Optimization (where mostly the technique of differential equations is involved) with Dr. David Green, Jr., and Dr. Peter Stanchev in the area of Computer based immage technologies and on applications of the information technology in education, and also with many others. Our joint publications in the resent years may give the evidence for the results of this collaboration. This collaboration is an important part of the surrounding that makes me feel better and provides conditions to do research in the frame of very limited time left from our duty to teach much more than colleagues from other universities do.
 
Within the Institute
The Statistics Clinic is a good source of contacts with colleagues from other departments at Kettering University, to help them in solving their particular problems, and to start working on prospective joint projects. In this way a fruitful collaboration with Prof. Etim Ubong from the Department of Mechanical Engineering, was initiated in 1998, and some results on Design of Experiment (DOE) for a study of the fuel control of a V-6 Buick motor engine have been obtained. A Technical Report was issued within KU, and a papern was published, and another one is accepted for publishing in 2006. This collaboration continues with other projects involving statistics, or DOE in the work of an engineer researcher.
 
With researchers outside the Institute.
I like work in collaboration with others. It helps me immediately to adopt the current issue, to get a new challenging idea, or just an appeal, to share immediately my results with the closest expert in the field. It started with the collaboration with Dr. Eduard Danielyan during my PhD work in Moscow, Russia, it continued with the collaboration with many others, it continued in Bulgaria in closed collaborative work with my PhD students Khristo Karapenev, Chavdar Dokev, Kosta Yanev, Nikolai Kolev, Tran Zoan Fu, and to certain extend, with Dr. Chukova. This collaboration gave lots of results in my work with the colleagues Apostol Obretenov, Svetlozar Rachev, Maria Varbanova, Ivan Mirazchiiski, Liliana Boneva, Nikolai Yanev, Gero Gerov, Zaprian Zaprianov, Elena Karashtranova, and others. Thanks to them I always felt the friendly, nice and productive environment a young researcher needs in his or her career, especially when starting and gaining experience.
The closeness of my research interests with to those of researchers from other institutions and the occasional contacts with some of them at International meetings gathered me with professors Zohel Khalil and Jose Garrido from Concordia University in Montreal, Canada, with Prof. Jean-Pierre Dion from Universite de Quebec a Montreal , with Prof. Elart von Collani, and Herbert Vogt, from Wuerzburg University in Germany, with Prof. Mohammed El-Saidi from Ferris State, Big Rapids, Michigan. Recently, I actively work with Prof. Vladimir Rykov , from the Moscow University of Oil and Gas in Russia, with Prof. Zinovi Krougly from the University of Western Ontario, in London, Canada , with Prof. Mohammed El-Saidi from the Ferris University of Michigan, with Prof. Eugene Dshalalow from the Florida Institute of Technology Florida, with Prof. Jordan Jordanov from the University of Sofia, Bulgaria, with Prof. Nikolai Kolev from the University of Sao Paulo, Brazil. I am happy that I renewed my collaboration with my former Bulgarian colleagues and we started some new projects. Discussions, contacts, live interest to the subjects gave results in a series of joint publications with these researchers. I thank all of them for the good collaboration, for the mutual respect and permanent support and interest in what we use to and are doing, and in what we project to do in the nearest future. Especially I like to thank colleagues from Moscow, Montreal, London (Ontario), Michigan, and Brazil for their constant initiatives during the years and for the support they gave in the periods if time I needed at most.
