  • Decomposition principles applied to the dynamic production and work-force scheduling problem
  • 1987
  • In: Engineering Costs and Production Economics. - 0167-188X .- 1878-4011. ; 12:1-4, s. 39-49
  • Journal article (peer-reviewed)abstract
    • One of the most important problems in the production and inventory planning field, is the scheduling of production and work force in a dynamic environment. Although this problem can be formulated as a linear program, it is often quite difficult to solve directly, due to its large scale. Instead, it might be fruitful to use a decomposition approach. Decomposition, in general, means decomposing a difficult problem into several easier, or a sequence of easier problems which are later coordinated to reconstruct the original problem.In this report we discuss several possibilities of applying the most common decomposition principles, namely Benders (primal) and Datnzig-Wolfe (dual), as well as a relatively new decomposition method, called cross decomposition, to the dynamic, multiproduct production and employment planning problem. A number of special cases are also presented.

  • On the resemblance between the Kornai-Liptak and cross decomposition techniques for block-angular linear programs
  • 1990
  • In: European Journal of Operational Research. - : Elsevier BV. - 0377-2217 .- 1872-6860. ; 46:3, s. 393-398
  • Journal article (peer-reviewed)abstract
    • In this paper the resemblance is demonstrated between the master- and subproblems generated by the Kornai-Liptak algorithm and the subproblems obtained by using the cross decomposition method on linear optimization problems with block-angular structure. The significance of the similarity between these two algorithms becomes apparent considering the main disadvantage attributed to cross decomposition. In cross decomposition a master problem has to be solved from time to time since the subproblems alone do not always give a converging sequence of primal and dual solutions. But if the cross decomposition algorithm is modified in such a way that the successive primal and dual subproblem solutions are taken into consideration with equal weights, this results in the Kornai-Liptak algorithm for which convergence is guaranteed

  • Lung cancer in Estonia in 1968-87 : time trends and public health implications.
  • 1994
  • In: European Journal of Cancer Prevention. - 0959-8278 .- 1473-5709. ; 3:5, s. 419-425
  • Journal article (peer-reviewed)abstract
    • Changes in lung cancer incidence and mortality in Estonia were studied for 20 years (1968-87). A steady upward trend was observed for men and women. The 1983-87/1968-72 age-standardized incidence rate ratio was 1.22 (95% confidence interval (CI) 1.15-1.29) in men and 1.34 (95% CI 1.16-1.54) in women. The corresponding mortality rate ratio was 1.26 (95% CI 1.18-1.34) in men and 1.35 (95% CI 1.16-1.57) in women. The age-specific incidence and mortality rates increased clearly towards the younger birth cohorts. For men and women, the increase was most evident for the age group 45-64 years. In women there was a more rapid increase in incidence and mortality than in men. It may be a result of a substantial increase of tobacco smoking, particularly among women, after the World War II. The high and still rising occurrence of lung cancer is closely related to the high prevalence of smoking; in addition, high tar yields in domestic cigarettes could have been responsible for an elevated lung cancer risk during the past decades. There is not tobacco control programme in Estonia, and existing legislation and regulations do not defend the non-smoking population.
