Evaluation of a city logistics business model: Impact of cost, revenue and goods flow on profitability
- 2017

In: NOFOMA 2017 - PROCEEDINGS OF THE 29TH ANNUAL NORDIC LOGISTICS RESEARCH.

Conference paper (peer-reviewed)abstract
- Purpose Many city logistics initiatives have failed to become economically sustainable. The purpose of this paper is to explain the impacts of cost, revenue and goods flow variables on the economic performance of a business model for city logistics. Design/methodology/approach A cost/benefit analysis, with data from transport providers and the municipality, on a six-month pilot implementation of a city logistics concept is conducted. The concept combines consolidation with logistics services for private and municipal goods. Findings The results highlight relations between goods volumes, revenues, direct and indirect costs and profitability for private and municipal goods. Sensitivity analyses highlight the impact of changes in goods volumes, costing and pricing on the economic effects of the city logistics concept. The study shows that the relationship between goods volumes and profitability is not linear, but it follows a curve with logarithmic shape. It also shows that the terminal costs are much greater than the distribution costs and that the amount of goods is decisive for the total cost per parcel. Research limitations/implications The evaluation develops the knowledge for the value creation and value capture in business models for city logistics by describing the relative importance of various cost, revenue and goods volume variables. Practical implications Other city logistics initiatives get insights into general cost structures and the effect of goods volumes on economy of scale. Another implication is a need to focus more on terminal efficiency than distribution efficiency for total cost efficiency. Original/value The economic evaluation of the activities in city logistics initiatives is rare. The empirical insights about economic and goods volume variables are valuable for developing the knowledge of business models in city logistics.

The city logistics-based business model: a series of components
- 2017
-
In: ISL 2017 - PROCEEDINGS ON THE 22ND INTERNATIONAL SYMPOSIUM ON LOGISTICS.
-
Conference paper (peer-reviewed)abstract
- Purpose Empirical studies show that 96% of the city logistics projects failed to become permanent, mainly due to the lack of sustainable business models (Quak et al., 2014; Malhene et al., 2012). Accordingly, it was concluded that the need of business model specifically designed for city logistics is high (Benjelloun, 2010). However, researchers have yet to describe the components and their interrelations of the city logistics-based business model. In this context, the purpose of this paper is to identify and describe the components of the city logistics-based business model and their interrelations. Design/methodology/approach The paper makes a literature review of Osterwalder’s and Pigneur’s general business model and a literature and practice city logistics projects and identifies the components of the city logistics-based business model. Thus, the components of the city logistics-based business model are identified in parallel to the components described by Osterwalder and Pigneur in the general business model and the current projects. Findings The analysis led to identify and describe the components of the city logistics-based business model. The study highlights that the business model is a series of components. In addition, the study clarifies the owner and the scope of the business model. All the identified components provide insights into the city logistics-based business model. Research limitations/implications The proposed business model can be adopted by public and private authorities to design the business model of a city logistics initiative. A limitation of the study is that it only focuses on the european projects. Another limitation of the study is that it is focused only on the most reported projects and those that provide exemplars of the implementation of the business model. Practical implications The proposed business model can be implemented in various scopes in city logistics projects, and can engage all the sub-business models that are contained in the city logistics system. Original/value The research defines the city logistics-based business model and identifies and describes its components and their interrelations.

Wind Turbine Noise Effects on Sleep: The WiTNES study
- 2017
-
In: ICBEN 2017.
-
Conference paper (peer-reviewed)abstract
- Onshore wind turbines are becoming increasingly widespread globally, with the associated net effect that a greater number of people will be exposed to wind turbine noise (WTN). Sleep disturbance by WTN has been suggested to be of particular importance with regards to a potential impact on human health. Within the Wind Turbine Noise Effects on Sleep (WiTNES) project, we have experimentally investigated the physiological effects of night time WTN on sleep using polysomnography and self-reporting protocols. Fifty participants spent three nights in the sound exposure laboratory. To examine whether habituation or sensitisation occurs among populations with long-term WTN exposure, approximately half of the participants lived within 1km of at least one turbine. The remaining participants were not exposed to WTN at home. The first night served for habituation and one WTN-free night served to measure baseline sleep. Wind turbine noise (LAEq,indoor,night=31.9 dB) was introduced in one night. This exposure night included variations in filtering, corresponding to a window being fully closed or slightly open, and variations in amplitude modulation.
