Most Important Scientific Achievements:
One of the founder (together with the Polish mathematicians Marczewski and Ryll-Nardzewski) of the theory of stochastic set functions. This includes the publication of one of the first papers on random point processes in higher dimensional spaces and their generalizations. Also, the publication of one of the first papers on marked Poisson processes in abstract spaces and the proof of the so-called product space theorem. This theorem appears, among others, in the mathematical description of mobile telecommunication systems.
Initiator of the programming under probabilistic constraints research area, where the random variables are stochastically dependent. This initiation corrected the earlier formulation of 'chance constrained programming' by Charnes, Cooper and Symonds, who prescribed probability bounds individually for the stochastic constraints, neglecting to take into account dependence of the random variables involved.
Developed multivariate logconcavity theory which, among others, made it possible to prove the convexity of the probabilistic constrained problem for a wide class of the underlying multivariate probability distributions. These results have been widely applied, in addition to stochastic programming, in statistics, economics, mathematical analysis and convex geometry. In economics the basic theorem of logconcave measures, proved by Prékopa in 1971 and 1973, proves to be a fundamental aggregation theorem, also used in product differentiation etc.
Developed, together with his students and collaborators, algorithms and codes to numerically solve probabilistic constrained and other stochastic and nonlinear programming problems. Initiated and obtained new results for probabilistic constrained stochastic programming in case of discrete random variables.
Generalized Smirnov's theorem in order statistics and used the results to solve an inventory control problem. The model has widely been applied and is frequently called the 'Hungarian Inventory Control Model'.
Presented successful and novel applications to water reservoir system design, optimal water level regulation of a lake, inventory control, design in cooperating power systems, microeconomics (electrical energy sector of the Hungarian economy), financial planning and food service management.
More recently, developed the theory of univariate and multivariate discrete moment problems and their various applications to bounding probabilities and expectations. Discovered that a wide class of classical probability bounds are optimum values of LP's formulated in connection with discrete moment problems and presented a variety of new bounds for probabilities of Boolean functions of events and expectations. The applications of the above-mentioned theory include bounding and approximation of communication and transportation network reliability (the former one was a standard tool at AT&T). The probability distribution function of the length of the critical path in PERT, solutions of the (deterministic) satisfiability problem, approximate solutions of probabilistic constrained stochastic programming problems, calculation of multivariate integrals etc.
Prékopa also has a strong interest in the history of science. Discovered the origins of the necessary conditions of optimality in nonlinear programming. Recently wrote a long article about János Bolyai, the greatest Hungarian scientist, commemorating the 200th anniversary of his birth.


Major Applied Projects:
Study of the degradation and rearrangement processes of long chain molecules 1952-1956.
Design of statistical surveys (sampling from a finite population) 1958-1965.
Inventory control for industrial companies, 1962-1967. The result of this project was a new and since then widely applied inventory control model (sometimes termed "Hungarian inventory control model") that led to the saving of several billions (of Hungarian Forints)
Water reservoir system design and operation, 1968-1975. The results are: a new probabilistic constrained multi-period stochastic programming model applied to the large reservoirs on the Tisza river in Hungary; optimal regulation of the water level of Lake Balaton implemented and applied by the South Hungary Water Authority Computing Center; Design of serially linked reservoir system applied for a water system in South Hungary.
Optimal daily scheduling of the electric power generation using thermal power plants, 1972-1985. The result of this long term project is a large scale, mixed variable (continuous and 0-1 variable), specially structured, partly linear, partly quadratic programming model where the number of constraints is cca 1300, the number of continuous variables is cca 1700 and the number of 0-1 variables is cca 130. The solving algorithm was coded by co-workers and the problem was solved within 2 minutes by using an IBM 3031 computer. From the point of view of electric power system modelling the innovation was the joint handling of the power plants and the transmission system.
Catering and dietetic system on personal computer, 1983-1985. (Participation in similar previous projects headed by J.L. Balintfy in 1965-1967). The result was a computerized system that produces optimal daily menu planning where 700 foodstuffs and recipes for 700 dishes and 21 nutritional values are used in the calculation. The system handles the complete catering management problem for hospitals, solves special dietotherapeutic problems and computes optimal menu plans for sportsmen. It was in every day use in the Sport Hospital in Budapest.
Communication network reliability calculation for AT&T, 1993.
Optimization model for fiber manufacturing, AT&T, 1998-92.
Modelling the national debt management of Hungary (ongoing)
