Abstract

Purpose

This paper aims to contribute to the discussion of the experimental campaigns on Cultural Heritage buildings. By adopting integrated procedures it is possible to limit the invasiveness of the destructive techniques leading to reliable results. The purpose is the proper definition of the structural system, which represents the starting point of the following analysis's phases, not treated in this work. A methodology based on normative references and acknowledged non-destructive and partial destructive strategies has been conceived. The latter aims to an accurate comprehension of the structural information.

Design/methodology/approach

An integrated approach for the structural assessment of cultural heritage buildings is presented. The methodology defines an interdisciplinary procedure based on normative references, non-destructive and minor-destructive techniques. A funnel-shaped workflow is developed to characterize the structural system of the buildings. The non-destructive campaigns are widely extended. Then, in-depth analysis concerning partial demolitions and minor-destructive tests are performed. The dynamic identification of the building is executed to detect its global response. The final validation of the assumed mechanical values is obtained by comparing the experimental modes coming from the ambient vibrations and the analytical modes of the structural modelling.

Findings

This research belongs to the Protocol signed between the Municipality of Florence and Department of Earth's Science and Department of Architecture of the University of Florence for the seismic vulnerability assessment of relevant and strategic buildings.

Research limitations/implications

The descripted methodology is targeted for monuments and special buildings where the use of destructive techniques is not possible or unrecommended.

Social implications

Social implications are related to the conservation of Heritage buildings. The latter deals with: (1) risk assessment of the targeted buildings towards different hazard sources (e.g. earthquakes, floods); (2) knowledge path developed through non-invasive diagnostic campaigns oriented to the conservation of the manufact. Furthermore, the paper encourages towards the recognition of non-destructive techniques and ambient vibration tests for the achievement of higher knowledge levels.

Originality/value

This paper defines a funnel-shaped procedure defining hierarchical roles between the different available strategies. The originality of this contribution is firstly related to the methodological flowchart. It is targeted to limit the invasive tests and consequently achieving accurate levels of knowledge. Secondly, some novelty can be found in the adoption of improvement parameters from a regional database adopting a Bayesian approach.

Abstract

Purpose

To improve the efficiency and economy of electro-mechanical product's recycle process, this paper aims to propose a disassembly sequence planning (DSP) method to reduce additional efforts of removing extra parts in selectable disassembly.

Design/methodology/approach

The methodology has three parts, which includes a disassembly hybrid graphic model to describe the product disassembly information, an object inverse-directed method to optimize the disassembly design and a model reconstruction method to achieve a better DSP.

Findings

According to the disassembly cost criteria and the parameters of disassembly tools, the disassembly efficiency increases and the disassembly cost decreases due to the use of partial destructive mode compared with non-destructive mode. The proposed partial destructive DSP is more efficient and economical.

Research limitations/implications

Partial destructive disassembly mode cannot be used for the flammable or explosive component in the procedure of the DSP optimization algorithm.

Practical implications

DSP of an electric corkscrew is analyzed to investigate the accuracy and efficiency of the proposed method.

Originality/value

This paper proposes a partial destructive disassembly based DSP method for product disassembly, which provides a new approach for the disposal of end-of-life products.

Abstract

Purpose

The purpose of this study is to empirically examine how the seven human resource management (HRM) practises, namely, leadership development, professional investment, egalitarian practises, developmental appraisals, family-friendly practises, engagement practises and generous benefits, are associated with perceived organisational support (POS) and destructive deviance in the context of Indian organisational culture.

Design/methodology/approach

In total, 265 middle-level IT personnel provided the study's data. To test the suggested study hypotheses, confirmatory factor analysis and PROCESS Macros were used.

Findings

Results show that putting in place leadership development, professional investment, egalitarian practises, developmental appraisal, family-friendly practises, engagement practises and generous benefits generates POS that, in turn, significantly contributes to reducing destructive deviance. Additionally, POS was found to partially mediate the relationship between perceived HRM practises and destructive deviance.

Research limitations/implications

The results would help firms reduce detrimental employee deviation. To do this, managers must develop and put into effect the seven HRM practises, which demonstrate to workers that the organisation appreciates their contributions and cares about their well-being, thereby lowering disruptive deviance. In essence, IT businesses should carefully plan and implement the HRM practises they expressly want to use rather than mindlessly copying those of rival organisations. Furthermore, to adapt to the workforce's evolving needs, these HRM practises must be properly matched with both individual and organisational goals.

Originality/value

By including destructive deviance as a result of POS, this study adds to the body of research on organisational support theory. The literature on POS and negative behaviours will take a new turn with such a focus on destructive deviance. Additionally, this study encourages academics to investigate an underlying mechanism that accounts for how HRM practises affect employees' conduct. This study also adds to the sparse body of knowledge on POS for non-Western workers. The study's findings confirm that POS is a crucial concept for both Asian and Western workers.

Abstract

Purpose

The purpose of this paper is to present an interactive system to enable product design for disassembly and to offer robust and quick design solutions based on designers’ input.

Design/methodology/approach

The system utilizes an interactive questionnaire to communicate with the designer. The questionnaire is in the form of binary questions (Yes/No) and design questions that would enable the system to learn the objectives of the design. Solutions are based on a CAD supported design platform. The efficiency of each design is calculated using disassembly time as the metric of measurement using motion-time measurement (MTM). The designer would be able to make an informed decision with respect to component functionality, ease of disassembly and disassembly time. The paper presents a detailed framework and structure of this system.

Findings

The value of the system is corroborated by means of a case study of an actual product design. The system is structured to offer multiple solutions to a design problem so as to enable the designer to choose the option that best serves their needs.

Originality/value

This novel interactive system would accept customers’ design preferences as input and offer multiple solutions in order to solve the design problem. Process time is directly calculated using the MTM system of measurement by converting design features into time measurement units. Disassembly time can then be easily converted into disassembly cost by using standard conversion rates. The value to designers is obvious.

Abstract

Purpose

As the widely held perception is that retrofitting is a complicated process and is expensive, the purpose of this paper is to analyze cost effectiveness of retrofitting existing buildings in order to make them safer against earthquake and also to add child friendly features. This case study focuses on the simple method of retrofitting on rectangular single storey existing school buildings. The school buildings are of different types, based on material, shape and size, number of storeys and their vulnerability to earthquake is different case by case. The paper also outlines the process of vulnerability assessment and approach to retrofitting.

Design/methodology/approach

The paper is based on the data collected from a case study carried out in Aceh (Indonesia) as a part of an assessment of vulnerability of newly constructed school facilities and retrofitting them in order to increase their seismic performance.

Findings

One of the key findings of this study is that retrofitting can be achieved through the use of simple methods, tools and equipment and local human resource. This approach not only reduced the vulnerability of school children to earthquake disaster but also contributed to disseminate the message of culture of safety among the neighboring communities. Another major finding is that cost of retrofitting is less compared to the cost of demolition and rebuilding. The retrofitting option further saves the cost as it is time saving and the downtime is less. The retrofitting process and onsite training can also be an effective medium for dissemination of best construction practices in the community. The process also helps the local people to understand the context of risk and raise awareness on disaster risk reduction.

Research limitations/implications

The findings of this paper are not limited to vulnerability assessment and retrofitting of school building in Aceh. They can be replicated in other parts of Indonesia and countries having similar type of buildings.

Practical implications

The findings of this paper will be useful for decision makers to replicate similar processes in other types of schools in other areas. The findings will also be useful advocate disaster safer and child friendly schools.

Originality/value

The paper is unique in its findings that retrofitting of school buildings does not only make the schools safer and reduces the risk to children but is also cost effective compared to new construction.

Abstract

Purpose

To improve the efficiency of end-of-life product’s disassembly process, this paper aims to propose a disassembly sequence planning (DSP) method to reduce additional efforts of removing parts when considering the changes of disassembly directions and tools.

Design/methodology/approach

The methodology has three parts. First, a disassembly hybrid graph model (DHGM) was adopted to represent disassembly operations and their precedence relations. After representing the problem as DHGM, a new integer programming model was suggested for the objective of minimizing the total disassembly time. The objective takes into account several criteria such as disassembly tools change and the change of disassembly directions. Finally, a novel hybrid approach with a chaotic mapping-based hybrid algorithm of artificial fish swarm algorithm (AFSA) and genetic algorithm (GA) was developed to find an optimal or near-optimal disassembly sequence.

Findings

Numerical experiment with case study on end-of-life product disassembly planning has been carried out to demonstrate the effectiveness of the designed criteria and the results exhibited that the developed algorithm performs better than other relevant algorithms.

Research limitations/implications

More complex case studies for DSP problems will be introduced. The performance of the CAAFG algorithm can be enhanced by improving the design of AFSA and GA by combining them with other search techniques.

Practical implications

DSP of an internal gear hydraulic pump is analyzed to investigate the accuracy and efficiency of the proposed method.

Originality/value

This paper proposes a novel CAAFG algorithm for solving DSP problems. The implemented tool generates a feasible optimal solution and the considered criteria can help the planer obtain satisfactory results.

Abstract

The physical sciences, particularly wave motion and optics are examined in order to develop a set of analogies which can be applied to organisational theory and practice. Such concepts as diffraction and focus exhibit remarkable parallels in both form and content with many aspects of mainstream organisational and managerial theory. Furthermore, the pervasiveness of wave motion in the physical sciences is not dissimilar from the pervasiveness of organisations in the social sciences. A series of concepts is introduced and, with the aid of diagrams, placed in a managerial context.

Abstract

Purpose

To review the state-of-the-art in smart remanufacturing, highlighting key elements of an Industry 4.0 (I4.0) future that supports circular economy (CE) principles and offer a conceptual framework and research agenda to accelerate digitalisation in this sector.

Design/methodology/approach

The Scopus, Web of Science and ScienceDirect databases and search terms “Industry 4.0”, “Internet of things”, “Smart manufacturing” and “Remanufacturing” were used to identify and select publications that had evidence of a relationship between those keywords. The 329 selected papers were reviewed with respect to the triple bottom line (economic, social and environmental). The study benefited from advanced text quantitative processing using NVivo software and a complete manual qualitative assessment.

Findings

Changes in product ownership models will affect the remanufacturing industry, with the growth of product-service-systems seen as an opportunity to re-circulate resources and create value. This is being supported by changes in society, user expectations and workforce attributes. Key to the success of remanufacturing in an I4.0 future is the uptake of existing and emerging digital technologies to shorten and strengthen links between product manufacturers, users and remanufacturers.

Originality/value

Remanufacturing is recognised as a key CE strategy, which in turn is an important research area for development in our society. This article is the first to study “smart remanufacturing” for the CE. Its uniqueness lies in its focus on the remanufacturing industry and the sustainable application of I4.0 enablers. The findings are used to create a framework that links to the research agenda needed to realise smart remanufacturing.
