System dynamics models for decision making in product multiple lifecycles
2015
The main drivers for adopting product multiple lifecycles are to gain ecological and economic advantages. However, in most of the cases it is not straight forward to estimate the potential ecological and economic gain that may result from adopting product multiple lifecycles. Even though many researchers have concluded that product multiple lifecycles result in gain, there are examples which indicate that the gain is often marginal or even none in many cases. The purpose of this research is to develop system dynamics models that can assist decision makers in assessing and analysing the potential gain of product multiple lifecycles considering the dynamics of material scarcity. The foundatio…
Renewable electricity producing technologies and metal depletion: A sensitivity analysis using the EROI
2015
International audience; More and more attention is being paid to renewable technologies because they are seen as a great opportunity to disengage our society from its dependence on fossil fuels. Such flow-based energy resources that rely on solarenergy are supposed to lead us toward a sustainable energy future. However, because of their high capitalintensity, renewable technologies require large amounts of matter, including both common and rare metals.These metals require energy for their production, and more specifically for their extraction. The energy costassociated with metal extraction is linked to mineral ore grade, meaning that as depletion progresses, energycost increases. In additi…
Current research issues in production economics
2020
This Special Issue includes a selection of papers originally presented and discussed at the Twentieth International Working Seminar on Pro- duction and Operations Management, Innsbruck, February 19–23, 2018, and subsequently extended and improved. Production and Operations Management was established in the1970s as an academic discipline focusing on scientific topics treating the interface between engineering, management, and economics with a special emphasis on financial consequences of decisions in the produc- tion domain. The subject is interdisciplinary in nature and it therefore contains a wide range of topics. The Working Seminar included sessions such as supply chain management, innov…
Does a voluntary conservation program result in a representative protected area network?
2009
Abstract Conservation contracting has attained growing interest worldwide as a tool for protecting biodiversity in privately owned lands. In this policy, landowners receive payments from an environmental agency in exchange for land use practices that contribute to the supply of biodiversity. This approach may result in a conservation network which does not cover all focal ecological characteristics, because landowners determine the supply of potential targets. In addition, the contracts are typically allocated by using a scoring method that is not giving information on the representativeness of the species composition of the sites. In this study, we investigated what is the performance of a…
Culture and team production
2018
Abstract This paper addresses theoretically the question whether culture has an effect on economic performance in team production, and what would be an optimal team culture. The members of a team are guided both by economic incentives and by personal norms, weighed according to their prevailing level of materialism. We assume that personal norms evolve following a dynamic driven by a combination of psychological mechanisms such as consistency and conformism. The different vectors of materialism, consistency and conformism shared by the group result in a continuum of cultures characterized by different combinations of individualism and collectivism. Team culture turns out to be a fundamental…
Measurement of ERP-project success: findings from Germany and Austria
2016
The implementations of Enterprise Resource Planning (ERP) systems have increased rapidly world-wide over the last two decades. ERP projects are long lasting and complex activities, influencing main internal and external operations of organizations. As companies spend an immense investment on these projects, in the beginning managers are focusing on most common success factors to reach the main goal of a proper implementation. For evaluating ERP projects in retrospective, an applicable measurement of the whole implementation and its economic effects is essential. This research paper evaluates the most prominent ERP project success models mentioned in scientific literature and gives an overvi…
Bioenergy chain building: a collective action perspective
2014
Depletion of natural resources has become a key issue on the European policy agenda. Bottom-up measures have emerged in several countries with a view to promoting awareness campaigns and environmental sustainability, with the agenda set by individuals who start up collective initiatives at the local level. Such collective action provides an incentive to free-ride on the contribution of others. Social norms and the consequent behavior of individuals involved in collective action assume a key role in ensuring sustainable use of a public good, achieving significant, long-lasting success. The present study aims to ascertain which determinants most affect farmers’ willingness to contribute to co…
Risk assessment and profit sharing in business networks
2011
Abstract Nowadays network is the preferred governance form to conduct economic transactions. Network solution allows to reach flexibility maintaining cost and quality level. Since network concept refers to a great variety of organizational hybrids it is possible to choose the one that fits better market requirements. The new trends in inter-organization relationships push towards network solutions: companies are interested in relationships with partners and customers to overcome resource dependence, to enter too risky market or simply differentiate their business portfolio. The proposed research focuses on the network concept aiming at highlighting threats and opportunities to investigate t…
Building future nuclear power fleets: The available uranium resources constraint
2013
Abstract According to almost all forward-looking studies, the world′s energy consumption will increase in the future decades, mostly because of the growing world population and the long-term development of emerging countries. The effort to contain global warming makes it hard to exclude nuclear energy from the global energy mix. The availability of natural uranium resources is a major constraint in terms of meeting this demand. In line with the scenarios floated by various international organisations and taking into consideration only current uranium-consuming light water reactors technologies with slow neutrons, 4 to 7 Mt of uranium could be consumed by 2050, namely, all identified or know…
Cooperatives and Social Capital : A Theoretically-Grounded Approach
2019
Social capital is widely regarded as a collective resource with positive effects on the economic performance of cooperatives. This conclusion is based on the implicit assumption that social interactions between cooperative members would inexorably lead to the development of networks, norms and trust. This paper challenges the validity of this assumption. Conceptualizing social capital as a resource of the individual, it is argued that the interactions between cooperative members may lead to the establishment of a variety of complex social ties, some of which can negatively affect the economic performance of the organization. To illustrate this argument, the paper presents an exploratory cas…
