Abstract

Purpose

One way of overcoming logistics barriers (poor transportation, handling and storage properties) towards increased utilisation of biomass is to introduce a pre‐treatment process such as torrefaction early in the biomass‐to‐energy supply chain. Torrefaction offers a range of potentially beneficial logistics properties but the actual benefits depend upon how the supply chain is configured to address various elements of customer demand. Hence, the aim of this paper is to develop a framework for torrefaction configuration in a supply chain perspective for different types of customers.

Design/methodology/approach

Sophisticated pre‐treatment processes are yet to reach the commercialisation phase. Identification of possible supply chain configurations is in this paper done through a conceptual approach by bringing together knowledge from related research fields such as unrefined forest fuel, pellets and coal logistics with prescriptions for configuration derived from the subject area of supply chain management (SCM).

Findings

A framework that explicates different elements of supply and demand of torrefaction is proposed, and exemplified by three distinct supply chains. Depending on demand, torrefaction serves different purposes, bridging gaps in place, time, quality and ownership. Furthermore, different supply chain configurations will pose different requirements on torrefaction in terms of producing different product quality, durability, energy density and hydrophobicity of the pellets.

Research limitations/implications

The proposed framework entails a set of propositions, but requires further development through empirical studies using complementary research methods such as interviews or surveys and quantification through techno‐economical or optimisation from a supply chain perspective.

Practical implications

This paper provides a framework that can inform decisions makers in biomass‐to‐energy supply chains, in particular at torrefaction plants, on upstream and downstream implications of their decisions.

Originality/value

The findings have implications for biomass‐to‐energy supply chains in general, and in particular, the paper provides a supply chain perspective of pre‐treatment processes, where previous research has focused primarily on technical aspects of torrefaction.

Abstract

Purpose

Researchers began investigating the diffusion of renewable energy technologies (RETs) in the late 1990s, and, up to today, a variety of authors have presented different approaches to understand the special characteristics of RET diffusion. However, one factor has been thus far disregarded in the research: the influence of raw material prices on RET diffusion. The dependence of a multitude of technologies on raw material prices became especially apparent in recent years due to rather sudden and volatile price movements in raw material markets. Thus, the aim of this work is to contribute to the research by providing evidence for a direct linkage between raw material price developments and RET diffusion.

Design/methodology/approach

A theoretical framework used in this article derives from the concept of induced diffusion. This empirical study is based on publicly available data of 18 Organisation for Economic Co-operation and Development (OECD) countries over 20 years and uses multivariate regression analysis to identify the corresponding diffusion models for selected established and emerging RETs.

Findings

Results reveal that crude oil prices play a crucial role in the diffusion of emerging RETs. In addition, a joint reflection of induced diffusion and path dependencies as the theoretical foundation of RET diffusion models might be reasonable.

Originality/value

This paper makes a significant contribution to the literature on induced diffusion in the field of renewable energies by providing insights from publicly available data from 18 OECD-countries. The findings are highly relevant for managers of the energy industry and policymakers in this field.

Abstract

Purpose

This paper aims to present an overview of innovation in the construction sector, its forms, its inherent pitfalls and difficulties, and some underlying reasons for them. The familiar distinction between technical and organisational innovation is inapplicable in the fragmented construction industry.

Design/methodology/approach

This paper is based on systematic observation, accompanying many years' hands-on experience.

Findings

The processes of innovation in construction require that the innovator (possibly starting from a narrow idea or opportunity) broaden his/her view to take into account the impacts of the intended innovation on the priorities of other stakeholders, in an iterative process. In other words, orchestrated organisational changes must accompany – if not precede – technical innovation.

Research limitations/implications

This paper specifically describes the processes and constraints of innovation in the context of the construction sector.

Practical implications

Failure to take into account the dual obligation to innovate simultaneously on the organisational and technical fronts will lead to yet one more failed attempt. Such a failure represents a waste of time and effort, and a missed opportunity to contribute to improved construction.

Originality/value

This paper is based on a uniquely broad experience-based view of innovation, covering a period of more than five decades; this feedback from experience can help innovators directly and provide evidence for subsequent research.

Abstract

Purpose

The purpose of this paper is to examine the introduction of three specific fiscal flexible mechanisms such as VAT surcharges/discounts, surcharges on import/manufacture of risk substances and maturity land tax to implement a new environmental fiscal reform that aims to reduce pollutions and emissions and avoid a regressive impact on low-income households using a feedback system.

Design/methodology/approach

The idea behind this article is to explore alternative environmental taxation system that aims to foster the transition to social-ecological sustainability without affect negatively poor and low-income households. It looks at the potential of environmental fiscal reform in terms of environmental benefits and present in the first section, evidence of some economic regressive impact caused by environmental fiscal reform in European Union from previous empirical studies. The article then introduces of a feedback mechanism to create a repayment system, such as rebate or cash transfer to compensate the regressive effect of the levy being added to the consumer price affecting low-income households in a very short period and push consumers to buy alternative eco-friendly products and services and to stimulate the market to offer them.

Findings

Lowering VAT rate for green products and services has the potential to increase demand for sustainable products and services and stimulate green jobs. Surcharges on import and manufacture of risk substances play a significant role to discourage the import of hazardous and pollutant substances by putting price on them and push the industrial sector towards a medium and long-term transition. Lowering taxes rates for buildings in inner cities encourage improvements and renovations, while raising tax on peri-urban areas discourage land speculation in areas with higher grade of biodiversity. This fiscal mechanism indirectly will reduce private and public transport emissions caused by urban sprawling and travel costs, reduce public infrastructure costs for connecting suburban area to the inner city and reduce the loss of urban-edge farmland area that are vital for smart urban growth.

Originality/value

The previous studies on the economic impact of the on environmental fiscal reform analysis, have focused on environmental aspects, economic growth and employment, but little on the regressive impact in short and medium terms on least wealthy sections of society. The proposed feedback mechanism aims to reduce distortion and inequalities caused by surcharges on existing taxation to low-income using monetary repayment measures, especially for products and services with elastic demand and no substitutes.

Abstract

Purpose

Because mobile manipulators are unable to climb stairs, the elevator operation is a crucial capacity to help those kinds of robot systems work in modern multifloor buildings. Here, the elevator button manipulation is considered as an efficient approach to fulfill that requirement. Previously, some studies presented elevator button recognition algorithms while some others designed schemes for the button manipulation work. However, the mobile robot, the manipulator and the camera in their robot systems are asynchronous. Besides, the time-consuming calibration for the camera is inevitable, especially in changeable environments. This paper aims to present an alternative method for the elevator button manipulation to overcome mentioned shortcomings.

Design/methodology/approach

In this paper, the elevator button manipulation is conducted by using the visual-based self-driving mobile manipulator in which the autonomous mobile robot, the manipulator and the camera cooperate more efficiently. Namely, the mobile robot does not need to be located exactly in front of the elevator panel as the manipulator has the ability to adjust the initial frame of the camera based on the system kinematic synchronization. In addition, the proposed method does not require the real world coordinates of elevator buttons, but uniquely using their pixel positions. By doing this, not only is the projection from two-dimensional pixel coordinates to three-dimensional (3D) real world coordinates unnecessary, but also the calibration of the camera is not required.

Findings

The proposed method is experimentally verified by using a visual-based self-driving mobile manipulator. This robotic system is the integration of an autonomous mobile robot, a manipulator and a camera mounted on the end-effector of the manipulator.

Research limitations/implications

Because the surface of the elevator button panel is usually mirror-like, the elevator button detection is easily affected by the glare and the brightness of the environmental light condition.

Practical implications

This robot system can be used for the goods delivery or the patrol in modern multifloor buildings.

Originality/value

This paper includes three new features: simultaneously detecting and manipulating elevator buttons without the projection from pixel coordinates to 3D real world coordinates, a kinematic synchronization to help the robot system eliminate accumulated errors and a safe human-like elevator button manipulation.

Abstract

Purpose

The purpose of this paper is to propose a risk-sharing model to coordinate the decision-making behavior of players in a cassava-based bioethanol supply chain under random yield and demand environment, so as to mitigate the yield and demand uncertainty risk and improve the bioethanol supply chain resiliency and performance.

Design/methodology/approach

The decision-making behavior under three models, namely, centralized model, decentralized model and risk-sharing model, are analyzed. An empirical test of the advantages and feasibility of the proposed risk-sharing model, as well as the test of yield uncertainty risk, risk-sharing coefficients and randomly fluctuating cassava market price on the decision-making behavior and performances are provided.

Findings

Though the proposed risk-sharing model cannot achieve the supply chain performance in the centralized model, it does help to encourage the farmers and the company to increase the supply of cassava and achieve the Pareto improvement of both players compared to the decentralized model. In particular, these improvements will be enlarged as the yield uncertainty risk is higher.

Practical implications

The findings will help decision makers in the bioethanol supply chain to understand how to mitigate the yield uncertainty risk and improve the supply chain resiliency under yield and demand uncertainty environment. It will also be conducive to ensure the supply of feedstock and the development of the bioethanol industry.

Originality/value

The proposed risk-sharing model incorporates the yield uncertainty risk, the random market demand and the hierarchical decision-making behavior structure of the bioethanol supply chain in the model.

Abstract

Purpose

Organizations face challenges in volatile, uncertain, complex and ambiguous (VUCA) environments. It is vital to manage the change’s rate and magnitude in new and different ways to stay competitive. This study focuses on the phenomenon of scenario planning that can help organizations proactively plan for, react and adapt to VUCA forces if and when they occur.

Design/methodology/approach

Based on an extensive academic and practitioner literature review, we posit that corporate scenario planning involves eight different practical applications and associated benefits. These include risk identification, assessing uncertainty, organizational learning, options analysis, strategy validation and testing, complex decision-making, strategic nimbleness and innovation. We offer a novel typology and propose a more complete and holistic model of the scenario planning application and its intended outcomes. Mini-case studies from various sectors illustrate the process. The model demonstrates the relationship between different benefit-driven applications - inputs, process and output benefits – and identifies opportunities for further research.

Findings

A previous typology study classified “what” and “why” related scenario planning research and literature. However, the why or associated benefits were not broken down at any level of detail, representing a gap in explaining the actual value of this management tool. The current study proposes a novel “why” focused typology of scenario planning benefits based on an extensive literature review. The novel typology adorned several benefits of scenario planning in an integrated model explained using systems theory. These benefits included risk, uncertainty, options analysis, strategic flexibility, complex decision-making, strategy testing and validation, innovation and organizational learning.

Originality/value

First time in the literature, the relationship between input, process and output benefits of scenario planning is explained using systems theory. The novel typology proposed illustrates the practical applications of scenario planning in one complete model.

Abstract

Purpose

While there is established research that explores individual innovations across countries or developments in a specific health area, there is less work that attempts to match national innovations to specific systems of health governance to uncover themes across nations.

Design/methodology/approach

We used a cross-comparison design that employed content analysis of health governance models and innovation patterns in eight OECD nations (Australia, Britain, Canada, France, Germany, the Netherlands, Switzerland, and the United States).

Findings

Country-level model of health governance may impact the focus of health innovation within the eight jurisdictions studied. Innovation across all governance models has targeted consumer engagement in health systems, the integration of health services across the continuum of care, access to care in the community, and financial models that drive competition.

Originality/value

Improving our understanding of the linkage between health governance and innovation in health systems may heighten awareness of potential enablers and barriers to innovation success.
