PISa – powered two wheeler integrated safety: development, implementation and testing of PTW integrated safety systems

The Powered two wheeler Integrated Safety (PISa) project, funded by the European Commission within the 6th Framework, aimed at identifying, developing and testing new technologies to provide integrated safety systems (ISS) for a range of powered two wheelers (PTWs) to improve primary safety and link to secondary safety systems. From the analysis of representative crashes involving motorcycles and mopeds, a list of safety systems was prioritised in terms of their contribution to crash avoidance or injury severity reduction. These systems were integrated onto two different types of PTW: a large scooter and a light motorcycle. Experimental tests with the demonstration vehicles showed the potential benefits of the PISa systems compared to unequipped PTWs. Further system development is required before testing the demonstration vehicles with non-professional riders

GAME THEORY APPLICATIONS IN CONSTRUCTION ENGINEERING AND MANAGEMENT / LOŠIMŲ TEORIJOS TAIKYMAS STATYBOS INŽINERIJOS IR VALDYMO SRITYSE

Game theory usually analyses decision‐making processes in various fields. There are different methods of solving decision related problems. Game theory focuses on problem solution from one player s point of view, while game theory emphasizes its analysis in the interaction among many players. Much of game theory is concerned with finite, discrete games, which have a finite number of players, moves, events, outcomes, etc. Many researchers in different research fields’ work applied the game theory in: construction engineering, management area. The article presents review of 42 years of scientific work of Professor Friedel Peldschus in the fields of game theory application in construction engineering and management. A review of scientific achievements and activity of Professor Friedel Peldschus, focusing on his research. Santrauka Taikant lošimų teoriją analizuojami sprendimu priemimo procesai įvairiose srityse. Yra įvairiu būdų spręsti problemas. Lošimu teorija gali būti orientuota į problemą vieno lošejo požiūriu ir gali analizuoti daugelio lošeju tarpusavio sąveiką. Daugiausiai lošimu teorija susijusi su galutiniais atskirais lošimais, kurių ribotas dalyvių skaičius, judėjimas, įvykiai, rezultatai ir t. t. Daugelis įvairių mokslinių sričių tyreju taiko lošimo teoriją statybos inžinerijos, valdymo srityse. Straipsnyje pateikiama prof. Friedel Peldschus 42 metų mokslinių tyrimų apžvalga apie lošimų teorijos taikymą statybos inžinerijos ir vadybos srityse, nagrinejami moksliniai pasiekimai ir veikla, atkreipiamas dėmesys į pasiektus mokslinių tyrimų rezultatus.

Multi-objective optimization of road design alternatives with an application of the MOORA method

Multi-objective analysis is a popular tool in many economic, managerial, constructional, etc. problems. The objective of this research is to develop and implement a methodology for multi-objective optimization of multi-alternative decisions in road construction. After a rough overview of multi-objective decision support for assessment of road design alternatives multi-objective optimization with discrete alternatives: MOORA (Multi-Objective Optimization on basis of Ratio Analysis) was selected. This method goes for a matrix of responses of alternatives on objectives, on which ratios are applied. This methodology is applicable to the problems with large numbers of scenarios and objectives. A case study demonstrates the concept of multi-objective optimization of road design alternatives and the best road design alternative is determined

Multi-objective decision-making for road design

Multi-objective analysis is a popular tool to solve many economic, managerial and construction problems. The objective of this research is to develop and implement a methodology for multi-objective optimization of multi-alternative decisions in road construction. After a rough overview of the articles dealing with the multi-objective decision and assessment of road design alternatives described by discrete values, Multi-Objective Optimization on the basis of the Ratio Analysis (MOORA) method was selected. This method focuses on a matrix of alternative responses on the objectives. A case study demonstrates the concept of multi-objective optimization of road design alternatives and the best road design alternative is determined
