Asset Life Cycle Management in Finnish Water Utilities

The aim of this paper is to improve the water industry asset life cycle management framework towards more resilient water services in Finland. This paper is based on a literature study and a web-based semi-structured thematic interview, in which the Finnish water utility managers identified the current status of their utilities’ asset management. The water services professionals are extremely worried that, by and large, water and sewage networks are still deteriorating, although the networks are nowadays rehabilitated more systematically. The survey reveals that although most of the surveyed utilities have adopted several processes and sub-processes of asset management, and a few utilities are even using some asset management guides, as a whole a strategic approach to and a comprehensive framework for optimized management of physical assets are not practiced. Therefore the development and introduction of specific asset management guidelines should be considered. In order to support successful usage of the asset management framework, the basic concepts and principles of engineering asset management should be included in educational and professional development programs, in particular at the university level.

Review of Oil and Gas Development Life Cycle Project Management (LCPM)

The effective implementation of the project management plays a core roll in avoiding bad project use effect and waste of funds, caused by asset management planning and design errors or equipment selection errors;meanwhile, it can effectively improve the operational efficiency of enterprise assets, lower operating costs and save resources. In June 1974, A. Gordon published a paper “3L Economics Concept” as the starting point, on the “Building and Quantity Surveying”, which is organized by the Royal Institution of Chartered Surveyors. In this paper, a review of domestic and foreign research, from 1974 to 2015, on the total life cycle management progress will be given, and then a comment on it will be established. After detailed investigation and analysis of related materials, we can draw a conclusion: the study of the oil and gas development project lifecycle management is just beginning now. Hence, building the whole life cycle planning index system in line with the characteristics of oil and gas development project is very necessary.

PRODUCT DATA PREDICTION WITH UNCERTAINTY IN PRODUCT LIFE CYCLE DESIGN

Various kinds of data are used in new product design and more accurate datamake the design results more reliable. Even though part of product data can be available directlyfrom the existing similar products, there still leaves a great deal of data unavailable. This makesdata prediction a valuable work. A method that can predict data of product under development basedon the existing similar products is proposed. Fuzzy theory is used to deal with the uncertainties indata prediction process. The proposed method can be used in life cycle design, life cycleassessment (LCA) etc. Case study on current refrigerator is used as a demonstration example.

Government-led Green Supply Chain Management

Enterprises must be concerned about the environment when seeking economic benefit. However,because of the defect of the market economy,enterprises are difficult to carry out green supply chain management spontaneously. In order to solve the above problem,the feasibility of the government as an external driving force to lead the implementation of green supply chain management was studied,and then a mixed guidance model of enterprise green supply chain management was established. In addition,the mechanisms of the government encouraging enterprises to implement green supply chain management were discussed,including negative punitive measures( fines and taxes) and positive incentive measures( subsidies and tax reduction) and the supplementary function of environmental credit system policy to realize government-led green supply chain management,which provides certain guiding for achieving the sustainable development of enterprises and society.

LCA in Environmental Management Systems—Results of Individual Interviews with Selected Enterprises from Poland and Sweden

Life Cycle Assessment (LCA) is an analytical tool used for the environmental optimization of products and services within the entirety of its life cycle. ISO 14040 recommends use of the technique in numerous areas of environmental management such as in designing for the environment, eco-labelling, environmental communications and the assessment of the effects of environmental activities. Despite being theoretically feasible, certain applications of the ecological assessment of a life cycle such as the possibility of identification and evaluation of environmental aspects with the use of LCA are, in practice, still new to many environmental managers. With its strong points, the technique seems to be a valuable tool, especially in the context of apparent concepts of Product-Oriented Environmental Management Systems (POEMS). In order to verify the hypothesis, the author decided to verify the level of use of LCA in the area of identification and assessment of environmental aspects in selected organizations. Therefore, questionnaire interviews were conducted with representatives of selected Polish and Swedish enterprises who, at the time of the interview, had certified environmental management systems. The organizations were analyzed with respect to applied methods and techniques used for identification and assessment of environmental aspects as well as the degree of use of LCA both in this respect and in other areas of environmental management. This paper will present the results of this research and conclusions.
