1.	Aardal, Karen, et al. (author) 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.

3.	Abeysekera, John D.A. (author) A comparative study of body size variability between people in industrialised countries and industrially developing countries, its impact on the use of imported goods 1987 In: Ergonomics in developing countries. - Geneva : Arkansas Philological Association. - 9221057550 ; , s. 65-91 Conference paper (peer-reviewed)
4.	Abeysekera, John D.A., et al. (author) A head-model reconstruction based upon photogrammetric data from Sri Lankan adult males relevant to the design of headgear 1989 In: Journal of Human Ergology. - 0300-8134. ; 18:2, s. 199-211 Journal article (peer-reviewed)abstract Due to the large variability in heads and faces in one population, the standard anthropometric dimensions of the head, measured from anatomical landmarks alone, may not suffice for the design of fitting headgear, e.g., helmets. To provide adequate data of the shapes and contours of the head to the designer, appropriate head models sculptured using comprehensive head dimensions, must be developed. This paper describes (a) a procedure of collecting comprehensive anthropometric data of the head using a photogrammetric method and (b) a simple sculpturing technique to reconstruct a head model of the user population
5.	Abeysekera, John D.A., et al. (author) Body size data of Sri Lankan workers and their variability with other populations in the world : its impact on the use of imported goods 1987 In: Journal of Human Ergology. - 0300-8134. ; 16:2, s. 193-208 Journal article (peer-reviewed)
6.	Abeysekera, John D.A., et al. (author) Body size variability between people in developed and developing countries and its impact on the use of imported goods 1989 In: International Journal of Industrial Ergonomics. - : Elsevier BV. - 0169-8141 .- 1872-8219. ; 4:2, s. 139-149 Journal article (peer-reviewed)abstract The Industrially Developing Countries (IDC) today, to a great extent, depend on Industrialized Countries (IC) for the supply of most industrial goods. An attempt has been made to ascertain the degree of design incompatibility experienced by users of these imported goods due to differences in the body sizes of people in producer and user countries. A comparative study of variations in body sizes is made from data available in literature and from anthropometric surveys. The results reveal differences in almost every part of the human body. The need for reliable anthropometric data in respect of IDC is stressed. Urgent measures are required to introduce changes in equipment, particularly for the benefit of users in IDC.
