- Smart growth (SG) is widely adopted by planners and policy makers as an environmentally friendly way of building cities. In this paper, we analyze the environmental validity of the SG-approach based on a review of the scientific literature. We found a lack of proof of environmental gains, in combination with a great inconsistency in the measurements of different SG attributes. We found that a surprisingly limited number of studies have actually examined the environmental rationales behind SG, with 34% of those studies displaying negative environmental outcomes of SG. Based on the insights from the review, we propose that research within this context must first be founded in more advanced and consistent knowledge of geographic and spatial analyses. Second, it needs to a greater degree be based on a system's understanding of urban processes. Third, it needs to aim at making cities more resilient, e.g., against climate-change effects.

Original equipment manufacturer (OEM)-supplier integration to prepare for production ramp-up
- 2019
-
Ingår i: Journal of Manufacturing Technology Management. - : Emerald Group Publishing Limited. - 1741-038X .- 1758-7786. ; 30:2, s. 506-530

Tidskriftsartikel (refereegranskat)abstract
- Purpose: Although prior research provides evidence that production ramp-up is often disrupted by supplier-related problems, it fails to discuss how the original equipment manufacturer (OEM) and various types of suppliers integrate their functions and operations to secure preparations for production ramp-up. The purpose of this paper is to investigate OEM–supplier integration in a new product development (NPD) project to prepare for production ramp-up.Design/methodology/approach: The results presented in this paper are based on a real-time, longitudinal study of a single collaborative NPD project in the mechanical engineering industry. The NPD project involves seven suppliers and it is carried out in a large Swedish company (the OEM) and fits the theory-elaborating approach of this research.Findings: This study argues that the aspect of timing in OEM–supplier integration, the OEM’s research and development (R&D) attitude toward collaboration and the OEM’s (R&D) operating procedure are challenges affecting the preparation for production ramp-up. The following three mechanisms to facilitate OEM–supplier integration in order to prepare for production ramp-up are also discussed: the mediator’s role, the OEM’s face-to-face meeting at the project level and suppliers’ formal face-to-face meetings with the OEM and internally.Originality/value: This paper elaborates on and extends prior research on production ramp-up by conducting an empirical analysis that incorporates supplier integration in NPD. It bridges the gap between the literature on production ramp-up and on supplier integration in NPD and clearly indicates that supplier integration is an important prerequisite for successful production ramp-up.

The Pedestrian Network Concept : A Systematic Literature Review
- 2023
-
Ingår i: Journal of Urban Mobility. - : Elsevier. - 2667-0917. ; 3
-
Tidskriftsartikel (refereegranskat)abstract
- The design of urban spaces that foster sustainable practices requires new analytical and structural approaches to spatial planning. An appropriate pedestrian network could significantly contribute to sustainable urban development goals, particularly by promoting sustainable mobility and pedestrian friendliness. With such goals, several attempts have been made to develop suitable models for pedestrian networks. However, something that is missing from the current literature is a framework that incorporates the main findings of the various studies as an integrated concise concept of the pedestrian network. To address this knowledge gap, this paper reviews studies on pedestrian networks and evaluates this concept based on the systematic 3W1H analysis method, which asks where, what, who, and how. In essence, the following questions are thus analyzed: Where is the pedestrian network located, What criteria play a role in the pedestrian network's performance, Who uses the pedestrian network, and How can the pedestrian network be analyzed? In this context, a systematic literature review is carried out by investigating studies conducted during the period 2001 to 2023 that appear in the Scopus database. The paper presents the results of the review of a selection of 67 papers dealing with pedestrian networks. Findings show that different models have been developed based on particular characteristics. Overall, researchers aimed to identify the most suitable network based on specific criteria for optimizing the walking experience in urban areas. By synthesizing the findings reported in these papers, this paper arguably contributes to a more comprehensive understanding of pedestrian networks, provides insights into the prioritization of design phases, facilitates the use of pedestrian network assessment models for future research, and creates a bigger picture for urban planners with a multidimensional view to a new sustainable urban structure.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The 16 churches of Chiloé in southern Chile, recently inscribed on UNESCO’s World Heritage List, represent the only example in Latin America of a rare form of ecclesiastical wooden architecture. They were built on the initiative of the Jesuit Peripatetic Mission in the 17th and 18th centuries and bear testimony to a successful fusion of indigenous and European culture and technical expertise. Most of these churches are in immediate need of restoration and maintenance. The present paper summarises experience and impressions acquired by the authors during a trip made to Chile in June 2002. The purpose of the trip was to establish contacts with people and organisations that are linked to the care and maintenance of the traditional wooden churches of Chiloé. In this context it has been of mutual interest to find out in what possible ways Scandinavian resources and know-how could be utilised and implemented in the process of restoring and maintaining these churches. The recently developed Maintenance Management System (MMS), capable of structuring condition surveys and assessments, as well as being an aid to plan and follow up conservation and maintenance work, might prove a suitable and elaborate alternative to traditional systems of building management and documentation. In addition, a brief description is presented of various tasks identified that could tentatively be the basis for mutual exchange of know-how, culture and traditions as well as of researchers, students and other resources, between the partners in Chile and in Sweden and Norway. These tasks address issues linked to aspects of both the physical maintenance of these churches and of their socio-cultural significance today and in the future.

Introduction of large-scale biofuel production in a district heating system - An opportunity for reduction of global greenhouse gas emissions
- 2014
-
Ingår i: Journal of Cleaner Production. - : Elsevier BV. - 0959-6526 .- 1879-1786. ; 64:1, s. 552-561
-
Tidskriftsartikel (refereegranskat)abstract
- In this study, cooperation between Stockholm's transport and district heating sectors is analysed. The cooperation concerns the integration of biofuel polygeneration production. A MODEST optimisation model framework is used, assuming various energy market and transport sector scenarios for the year 2030. The scenarios with biofuel production and increased biofuel use in the region are compared with reference scenarios where all new plants introduced into the district heating sector are combined heat and power plants, and the share of biofuel used in the transport sector is the same as today. The results show that the cooperation implies an opportunity to reduce fossil fuel consumption in the sectors by between 20% and 65%, depending on energy market conditions and assumed transport sector scenarios. If we consider biomass an unlimited resource, the potential for greenhouse gas emissions reduction is significant. However, considering that biomass is a limited resource, the increase of biomass use in the district heating system may lead to a decrease of biomass use in other energy systems. The potential for reduction of global greenhouse gas emissions is thus highly dependent on the alternative use of biomass. If this alternative is used for co-firing in coal condensing power plants, biomass use in combined heat and power plants would be more desirable than biofuel production through polygeneration. On the other hand, if this alternative is used for traditional biofuel production (without co-production of heat and electricity), the benefits of biofuel production through polygeneration from a greenhouse gas emissions perspective is superior. However, if carbon capture and storage technology is applied on the biofuel polygeneration plants, the introduction of large-scale biofuel production into the district heating system would result in a reduction of global greenhouse gas emissions independent of the assumed alternative use of biomass.

Supply and demand chain integration: : A case study conducted in the packaging industry
- 2013
-
Ingår i: Packaging technology & science. - : Wiley. - 0894-3214 .- 1099-1522. ; :1, s. 51-63

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this work was to study the packaging supplier and the integration of integrating packaging suppliers into the supply and demand chain (SDC). The packaging industry has been analyzed using a structured market analysis, and the companies studied have been positioned in an integration model for packaging suppliers. In addition, case studies were conducted to study the development of the packaging industry and its integration within the SDC in the Scandinavian region. The analysis shows that there are gaps in the business relations between the packaging companies studied and the SDC. Most of the packaging suppliers were not integrated into the SDC. Valuable information, available in the network, seldom reaches the packaging supplier who holds the knowledge necessary to create and offer innovative packaging solutions. The article provides an empirical exploration into the field of packaging, logistics and SDC integration and an original conceptual framework that could serve as a theoretical framework for future research work applied in the packaging industry and an interesting business model to the increase understanding of packaging supply chain integration.

- Energy efficiency is a priority goal and an important part of the transformation to a more sustainable society. The industrial sector is an important actor in this setting. In this chapter we outline the major principles for energy efficiency and energy management in industry and discuss how to develop the energy management perspective with theories from social science focusing on how situated actions, tacit knowledge and social networks can influence decision-making. By cross-pollinating fields that do not usually meet, the aim is to develop new insights contributing to existing research. We conclude that an energy management model is necessary, which can be adjusted to the local context in which it will be used. We also suggest an energy management model focusing the importance of knowledge and communication.

Energy efficiency as a wicked problem
- 2019
-
Ingår i: Sustainability. - : MDPI AG. - 2071-1050. ; 11:6
-
Tidskriftsartikel (refereegranskat)abstract
- Together with increased shares of renewable energy supply, improved energy efficiency is the foremost means of mitigating climate change. However, the energy efficiency potential is far from being realized, which is commonly explained by the existence of various barriers to energy efficiency. Initially mentioned by Churchman, the term wicked problems became established in the 1970s, meaning a kind of problem that has a resistance to resolution because of incomplete, contradictory, or changing requirements. In the academic literature, wicked problems have later served as a critical model in the understanding of various challenges related to society, such as for example climate change mitigation. This aim of this paper is to analyze how the perspective of wicked problems can contribute to an enhanced understanding of improved energy efficiency. The paper draws examples from the manufacturing sector. Results indicate that standalone technology improvements as well as energy management and energy policy programs giving emphasis to standalone technology improvements may not represent a stronger form of a wicked problem as such. Rather, it seems to be the actual decision-making process involving values among the decision makers as well as the level of needed knowledge involved in decision-making that give rise to the wickedness. The analysis shows that wicked problems arise in socio-technical settings involving several components such as technology, systems, institutions, and people, which make post-normal science a needed approach.

Industrial Energy Management Decision Making for Improved Energy Efficiency : €”Strategic System Perspectives and Situated Action in Combination
- 2015
-
Ingår i: Energies. - : MDPI AG. - 1996-1073. ; 8:6, s. 5694-5703
-
Tidskriftsartikel (refereegranskat)abstract
- Improved industrial energy efficiency is a cornerstone in climate change mitigation. Research results suggest that there is still major untapped potential for improved industrial energy efficiency. The major model used to explain the discrepancy between optimal level of energy efficiency and the current level is the barrier model, e.g., different barriers to energy efficiency inhibit adoption of cost-effective measures. The measures outlined in research and policy action plans are almost exclusively technology-oriented, but great potential for energy efficiency improvements is also found in operational measures. Both technology and operational measures are combined in successful energy management practices. Most research in the field of energy management is grounded in engineering science, and theoretical models on how energy management in industry is carried out are scarce. One way to further develop and improve energy management, both theoretically as well as practically, is to explore how a socio-technical perspective can contribute to this understanding. In this article we will further elaborate this potential of cross-pollinating these fields. The aim of this paper is to relate energy management to two theoretical models, situated action and transaction analysis. We conclude that the current model for energy management systems, the input-output model, is insufficient for understanding in-house industrial energy management practices. By the incorporation of situated action and transaction analysis to the currently used input-output model, an enhanced understanding of the complexity of energy management is gained. It is not possible to find a single energy management solution suitable for any industrial company, but rather the idea is to find a reflexive model that can be adjusted from time to time. An idea for such a reflexive model would contain the structural elements from energy management models with consideration for decisions being situated and impossible to predict.

Perceived Accessibility and Key Influencing Factors in Transportation
- 2022
-
Ingår i: Sustainability. - : MDPI. - 2071-1050. ; 14:17, s. 1-22
-
Forskningsöversikt (refereegranskat)abstract
- Accessibility is commonly assessed using indicators calculated from spatial data. Comparatively perceived accessibility cannot be adequately reflected by these calculated measures because it involves the perception to participate in spatially dispersed opportunities. This highlights the need to understand and consider perceived accessibility for planning and evaluation of transport systems from a complementary perspective. Therefore, this study aims to offer a systematic review concerning the interpretations of perceived accessibility in transport, its concept, major social drivers, barriers, evaluation methods and key influencing factors. This review also highlights the importance of perceived safety and service quality in public transport and their relationship with perceived accessibility in daily travel. The paper argues that perceived accessibility with due consideration of perceived safety and service quality will contribute to the development from mobility-based to accessibility-based planning.
