1. Introduction

Active collaboration between German--Lithuanian--Polish scientific triangle caused the new development trend of research. The research areas till 2009 were limited to Operational Research (OR) and Civil Engineering. Prof. E. K. Zavadskas raised the idea to analyse Operational Research and Civil Engineering in the context of sustainability. These issues were analysed at the 12th colloquium. As the consequence of new trend of research development the EURO Working Group OR in Sustainable Development and Civil Engineering (EWG-ORSDCE) was established.

2. The idea and development of German-Lithuanian-Polish scientific triangle

During thirty years of scientific cooperation of three academic centers, i.e. Leipzig University of Applied Sciences, Vilnius Gediminas Technical University and Poznan University of Technology, due to the main initiators Prof. E. K. Zavadskas, Prof. F. Peldschus and Prof. O. Kaplinski the active collaboration has started. Collaboration in exchanging of research achievements, consulting on publications, cooperating in joint papers, supporting the future research was realized through organization of colloquiums, which were held every two years in different academic centres (Kaplinski 2009a).

Five of mentioned colloquiums were organized in Germany, four held in Lithuania and three in Poland. Every colloquium from the first one held in 1986 and to the last had given the considerable contribution to the publication of research papers and books, development of further academic research, preparing doctoral dissertations and for international recognition (Fig. 1).

The initiating members of the first colloquium held in 1986 were Prof. K. Fiedler (Leipzig Higher Technical School), Dr F. Peldschus (Leipzig Higher Technical School) and Dr E. K. Zavadskas (Vilnius Civil Engineering Institute). The second colloquium was held in 1989 and representative from Poland Prof. O. Kaplinski was invited (Zavadskas 2008b).

The 11th German-Lithuanian-Polish Colloquium "Planning Instruments in Construction Management", which took place in Kolobrzeg, Poland in 2007, was organized by Poznan University of Technology. The major theme of this colloquium was planning instruments in construction management (Zavadskas 2008e).

There were also other subjects analysed such as development and usefulness of planning techniques, intelligent green construction, investment problems in cooperating countries, artificial intelligence, facility management, life cycle of objects, achievements and application of Multi-Criteria Decision Analysis (MCDA) and Multi-Criteria Decision Making (MCDM) methods (Kaplinski 2010).

In the colloquium further research on the aspects of operational research methods, sustainable development and its application for problem solution in civil engineering was initiated. The 11th colloquium was exceptional due to aspiration to make the achievements of colloquiums known to the scientists of other European Union countries, and the idea to create the working group of "Operation Research in Sustainable Development and Civil Engineering" has originated. Prof. E. K. Zavadskas on the basis of his long-term scientific research, with his former PhD students, now colleagues, initiated the implementation of the mentioned idea.

This purpose required further cooperation in the area of Sustainable Development and Construction problems (Zavadskas 2008b). The mentioned area was the core topic of the 12th colloquium, which was organized by Vilnius Gediminas Technical University.

The 12th German-Lithuanian-Polish Colloquium was held in Vilnius, Lithuania, on 20-24 May 2009. It was entitled "Sustainable Development in Civil Engineering and Multi-Attribute Decision Making". The chairman of International Programme Committee was Prof. Habil. Dr E. K. Zavadskas and responsibility to be the chairman of organizing committee was assumed by one of the first Prof. …
