The Use of Life Cycle Management Principles in Biosystems Engineering： A Pragmatic Approach to Solving Agri-industrial Sustainability Problems

LCM （life cycle management） is a systematic approach, mindset and culture that considers economic, social, and environmental factors among other factors in the decision making process throughout various business or organizational decisions that affect both inputs and outputs of a product or service life cycle. It is a product, process, or activity management system aimed at minimizing environmental and socio-economic burdens associated with an organization＇s product or process during its entire life cycle and value chain. LCM＇s application is gaining wider acceptance both in the corporate and governmental organizations as an approach to reduce ecological footprints and to improve the sustainability of human activities. But where and how can it be used in agricultural engineering applications？ This study highlights the potential areas of LCM application in agricultural and allied sectors and how it can be utilized. The study revealed that LCM tools such as design for environment and life cycle analysis can be used to evaluate the environmental impacts of-and to improve the products, equipment, and structures produced by biosystems engineers as well as the processes used to generate them.

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.

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.

Embedding Knowledge Management in Public Sector Procurement： Redesigning for the Knowledge Economy

There is a perception in the public, political, and trade discourse that private sector procurement performs ＂better＂ than does public sector procurement. This research considers whether this perception is justified. This paper proposes a conceptual framework for assessing issues that influence procurement performance. The framework takes into account the organization＇s business goals, its procurement principles, the design of its procurement capability, the intellectual capital or knowledge that is used to support procurement operations, and the use of knowledge management methods. To represent these factors, the framework adapts the conceptual framework proposed by McElroy （2002）, leverages Andriessen＇s （2005） characterization of intellectual capital, and adopts Bedford＇s （2012） description of the practice of knowledge management. The results, though preliminary and exploratory, suggest that factors which are more often practiced in the private sector than the public sector contribute to higher performance.

Design Technology Research of Aircraft Engine Health Management (EHM) Technologies

Aircraft engine is an important guarantee for aircraft safety, and its failure mode and health management have become the top priority.

A Critical Approach to the Tourism Management

Tourist destination and, generally, tourist activities not only represent an extraordinarily important economic factor, but also an instrument of knowledge and personal empowerment. Therefore, we can state that it is essential to ensure access to the tourism experience to all citizens, regardless of personal, social, economic conditions and any other nature which may limit the fruition of this asset. The role of tourism management is to develop effective strategic plan in order to guarantee a possible growth of a destination, without having a negative impact on the resources, either natural or civilian of the destination itself. Tourist destinations follow a life-cycle (evolution cycle) based on a price factor (a greater attractiveness of an area means a greater willingness to pay of the tourists) and a trend factor (related to the fame of the area and to the evolution of tourists’ tastes and habits). These factors mark the tourism in the contents and in the methods of production and consumption, related to the concepts of supply and demand, two dimensions that must be always connected with the principles of growth, accessibility and sustainability. This research paper aims to deepen the life-cycle approach of a tourist destination, underlining the option that the tourism management could offer to relaunch an area, however considering the principle of supportable growing.
