The authors consider the internal and external reserves of improving the quality of products at the enterprises that produce reinforced concrete. The research objective was to study and substantiate the external and internal factors, thus improving the effectiveness of quality management. The paper focuses on the use of such tool of sustainable development as "Six Sigma", which is considered as an important factor in product quality management. The paper also features the process of certification as an external tool that can improve quality management in the construction industry. The authors justified the necessity of mandatory certification of construction products when bidding for a tender. The paper also reviews the experience of sustainable production at reinforced concrete plants. The problems of product quality in the industry are of strategic nature and can cause economic, environmental, and other negative consequences. Quality management should become compulsory in the industry since its products are designed exclusively for the domestic market. As a result, its certification according to State Standards ISO 9001 or GOST R ISO 9001 is absolutely voluntary and performs only image-making functions. As far as tenders for state orders are concerned, mandatory certification may solve the existing problems with the quality of construction work. As internal quality management tool, the concept of "Six Sigma" can be useful for concrete works.

Six Sigma is a phenomenal quality management concepts which has helped many organizations to overcome quality crisis in the recent past. Six Sigma is observed as a very promising quality management tool for any organization to make its presence felt in the corporate world as it emphasizes on obtaining a fruitful solution to improve accuracy, reduce defect thereby reduce the cost and improve profits. The main objective of this investigation is to unearth the extent to which the companies have been benefitted due to Six Sigma implementation. This article presents the results based on the analysis of collective opinion of employees of various Indian manufacturing industries that have implemented Six Sigma. This research also examines interrelationship among various parameters defined in the research. The research revealed that industries are benefitted irrespective of their nature in terms of their growth, financial benefits, productivity and satisfaction of the customer. However, peoples’ equity that deals with the benefits that employees obtain after Six Sigma implementation is not certain. The research also revealed the existence of strong interrelationship among various parameters used to measure the success of Six Sigma.

Purpose – The purpose of this paper is to present the current status of a quality management practice in Serbia, in terms of the development and application of integrated managements systems (IMS), and research and implementation of Six Sigma and the related techniques. Design/methodology/approach – Two main aspects of total quality management (TQM) have been considered: institutional (organisational or strategic) aspect that corresponds to standardised management systems and their integration, and technical (quality engineering) aspect whose main contributor is Six Sigma. The findings of a comprehensive study on IMS implementation in Serbia have been presented, based on the results of a questionnaire that was sent to 54 organisations during 2013. Also, the significant technical improvements and tangible benefits of a recently conducted Six Sigma project were shown, including the application of the advanced quality engineering techniques within DMAIC method. Findings – Good QM practice in Serbia is improving, both in terms of the organisational (IMS) and technical (Six Sigma) aspect, that server as a good basis for the adoption of TQM in manufacturing companies from various sectors. It could be anticipated that these results will facilitate the adoption of an overall TQM culture in Serbia and leverage its future sustainability. Originality/value – This paper offers key insights into IMS and Six Sigma implementation in Serbia. This could encourage manufacturing organisations in developing countries to adopt IMS and Six Sigma, in order to boost the overall TQM culture and gain a competitive advantage.

The water quality management tool RIONET for river basins has been developed with regard to the EU Water Framework Directive. The management tool can simulate the water quality in catchment basins not only in the dimension of a single river but in whole river networks. A submodel of the IWA River Water Quality Model No. 1 is used in RIONET. The river model is based on the assumption that self purification processes in the river takes place both in the benthic biofilm and the bulk water phase. Laboratory experiments with sediment cores underline the major role of the benthic biofilm. The input parameters of the management tool such as volumetric flow rates from waste water treatment plants and flow velocities and discharge in the main river and its tributaries can be loaded directly from geographic information systems (GIS). The subcatchment basin of the river Bode in Saxon Anhalt was used for test runs of RIONET.
