Negotiations are common in many activities; the sectors of construction and real estate are not an exception: here the negotiations are an inseparable part of the real estate buying and selling process. The article analyses scientific research related to negotiations and presents the developed model for multiple criteria analysis of construction and real estate negotiations. The analysis of the negotiation processes in construction and real estate and the analysis of the relevant support for decision‐making in negotiations must be thorough; it must consider not only economic but also political, legal, socio‐cultural, psychological, consumer behaviour, technological, quality of life and other issues. The developed model enables to analyse the combination of the real estate negotiation process, the improvement of its efficiency through use of decision support and voice stress analysis technology and the participating stakeholder groups seeking their goals together with the influencing external macro and micro environment. The paper dwells on the components of this model. Santruka Derybos nuolatos vyksta daugelyje veiklos sričiu, neaplenkdamos ir statybos bei NT sektoriu, kur jos yra neatsiejama nekilnojamojo turto pirkimo ir pardavimo proceso dalis. Straipsnyje analizuojami mokslininku tyrimai derybu srityje ir pristatomas sukurtas statybos ir NT derybu daugiakriterines analizes modelis. Nagrinejant statybos ir NT derybu procesa bei taikoma parama derybu sprendimams priimti, būtina tai nagrineti išsamiai, kreipiant demesi ne tik i ekonominius, bet ir i politinius, teisinius, socialinius, kultūrinius, psichologinius, vartotoju elgsenos, technologinius, gyvenimo kokybes ir pan. klausimus. Sukurtas modelis leidžia analizuoti NT derybu procesa, jo efektyvumo didinima, taikant sprendimu paramos ir balso analizes technologijas, joje dalyvaujančias ir savo tikslus norinčias igyvendinti suinteresuotas grupes bei jas veikiančia išorine makro‐ ir mikroaplinka kaip visuma.

Within the municipal boundaries, municipalities themselves are usually the largest real estate owners and managers. Such significant amount of real estate property could be expected to be professionally managed; however, the situation is different. According to the latest publications, only about 25% of major European cities are able to follow the quantity and value of their real estate portfolios. The Lithuanian Free Market Institute has recently introduced its first Index of Municipalities in Lithuania and states that none of the Lithuanian municipalities has developed its real estate management strategy. This paper reviews the scientific research on municipal real estate management and analyses the system of real estate management in Lithuanian municipalities. The authors of the paper collaborated with the Association of Local Authorities in Lithuania as well as the representatives of municipalities, and together they identified the main problems of real estate management. On the basis of real estate management research and practice within Lithuanian municipalities the authors of the paper present a brand new model which would help to manage municipal real estate effectively by taking into account the priorities of strategic economic and social development tendencies of the region.

The negotiations are an inseparable part of the real estate buying and selling process. Currently real estate are characterized by the intensive creation and use of information, knowledge and automation (software, knowledge and decision support systems, neural networks, etc.) applications. It is commonly agreed that a better integration of information, knowledge and automation applications, as well use of voice stress analysis (one of biometric technologies) might be an efficient mean for decision making in real estate negotiations. Voice stress analysis can help the negotiators to distinguish between truth and lies, improve the value of decisions made, significantly speed up real estate sector processes, help to reach a better real estate sales and purchase agreement terms and decrease the overall cost of real estate search and negotiation processes. The authors’ objective is to improve the quality and efficiency of decision support systems. The article analyses scientific research related to negotiations and presents the developed Web-based Real Estate Multiple Criteria Negotiation Decision Support System with integrated voice stress analysis – a new generation of Decision Support Systems., Lietuviška santrauka. Derybos yra neatskiriama nekilnojamojo turto pirkimo ir pardavimo proceso dalis. Dabartiniam nekilnojamojo turto sektoriui būdingas intensyvus informacijos, žinių ir automatizavimo naudojimas bei kūrimas (programinė įranga, žinių ir sprendimų paramos sistemos, neuroniniai tinklai ir pan.). Sutariama, kad geresnis informacijos, žinių, automatizavimo, taip pat balso streso analizės (biometrinės technologijos) integravimas pagreitina nekilnojamojo turto sektoriaus veiklą. Balso streso analizė gali padėti derybininkams atskirti, kada sakoma tiesa, o kada meluojama, padidina priimamų sprendimų naudingumą, paspartina nekilnojamojo turto paieškos ir derybų procesus, padeda pasiekti naudingesnių pirkimo ir pardavimo sutarties sąlygų bei sumažina nekilnojamojo turto paieškos ir derybų proceso kainą. Straipsnio autoriai, siekdami pagerinti sprendimų paramos sistemų kokybę ir efektyvumą, analizuoja mokslininkų atliktų derybų srities tyrimų rezultatus ir pristato sukurtą nekilnojamojo turto derybų internetinę sprendimų paramos sistemą su integruota balso streso analizės technologija kaip naujos kartos sprendimų paramos sistemą.
