Abstract

Purpose

Building information modelling (BIM) is a digital representation of the physical and functional characteristics of a building. Its use offers a range of benefits in terms of achieving the efficient design, construction, operation and maintenance of buildings. Applying BIM at the outset of a new build project should be relatively easy. However, it is often problematic to apply BIM techniques to an existing building, for example, as part of a refurbishment project or as a tool supporting the facilities management strategy, because of inadequacies in the previous management of the dataset that characterises the facility in question. These inadequacies may include information on as built geometry and materials of construction. By the application of automated retrospective data gathering for use in BIM, such problems should be largely overcome and significant benefits in terms of efficiency gains and cost savings should be achieved.

Design/methodology/approach

Laser scanning can be used to collect geometrical and spatial information in the form of a 3D point cloud, and this technique is already used. However, as a point cloud representation does not contain any semantic information or geometrical context, such point cloud data must refer to external sources of data, such as building specification and construction materials, to be in used in BIM.

Findings

Hyperspectral imaging techniques can be applied to provide both spectral and spatial information of scenes as a set of high-resolution images. Integrating of a 3D point cloud into hyperspectral images would enable accurate identification and classification of surface materials and would also convert the 3D representation to BIM.

Originality/value

This integrated approach has been applied in other areas, for example, in crop management. The transfer of this approach to facilities management and construction would improve the efficiency and automation of the data transition from building pathology to BIM. In this study, the technological feasibility and advantages of the integration of laser scanning and hyperspectral imaging (the latter not having previously been used in the construction context in its own right) is discussed, and an example of the use of a new integration technique is presented, applied for the first time in the context of buildings.

Abstract

Purpose

The purpose of this paper is to analyse the thermal environment of two engineering testing centres cooled via different means using computational fluid dynamics (CFD), focussing on the indoor temperature and air movement. This computational technique has been used in the analysis of thermal environment in buildings where the profiles of thermal comfort parameters, such as air temperature and velocity, are studied.

Design/methodology/approach

A pilot survey was conducted at two engineering testing centres – a passively cooled workshop and an air-conditioned laboratory. Electronic sensors were used in addition to building design documentation to collect the required information for the CFD model–based prediction of air temperature and velocity distribution patterns for the laboratory and workshop. In the models, both laboratory and workshop were presumed to be fully occupied. The predictions were then compared to empirical data that were obtained from field measurements. Operative temperature and predicted mean vote (PMV)–predicted percentage dissatisfied (PPD) indices were calculated in each case in order to predict thermal comfort levels.

Findings

The simulated results indicated that the mean air temperatures of 21.5°C and 32.4°C in the laboratory and workshop, respectively, were in excess of the recommended thermal comfort ranges specified in MS1525, a local energy efficiency guideline for non-residential buildings. However, air velocities above 0.3 m/s were predicted in the two testing facilities, which would be acceptable to most occupants. Based on the calculated PMV derived from the CFD predictions, the thermal sensation of users of the air-conditioned laboratory was predicted as −1.7 where a “slightly cool” thermal experience would prevail, but machinery operators in the workshop would find their thermal environment too warm with an overall sensation score of 2.4. A comparison of the simulated and empirical results showed that the air temperatures were in good agreement with a percentage of difference below 2%. However, the level of correlation was not replicated for the air velocity results, owing to uncertainties in the selected boundary conditions, which was due to limitations in the measuring instrumentation used.

Research limitations/implications

Due to the varying designs, the simulated results of this study are only applicable to laboratory and workshop facilities located in the tropics.

Practical implications

The results of this study will enable building services and air-conditioning engineers, especially those who are in charge of the air-conditioning and mechanical ventilation (ACMV) system design and maintenance to have a better understanding of the thermal environment and comfort conditions in the testing facilities, leading to a more effective technical and managerial planning for an optimised thermal comfort management. The method of this work can be extended to the development of CFD models for other testing facilities in educational institutions.

Social implications

The findings of this work are particularly useful for both industry and academia as the indoor environment of real engineering testing facilities were simulated and analysed. Students and staff in the higher educational institutions would benefit from the improved thermal comfort conditions in these facilities.

Originality/value

For the time being, CFD studies have been carried out to evaluate thermal comfort conditions in various building spaces. However, the information of thermal comfort in the engineering testing centres, of particular those in the hot–humid region are scantily available. The outcomes of this simulation work showed the usefulness of CFD in assisting the management of such facilities not only in the design of efficient ACMV systems but also in enhancing indoor thermal comfort.

Abstract

Purpose

The main purpose of the research is to develop a comprehensive model for measuring overall equipment effectiveness in the capital‐intensive industry such as steel, oil and chemical companies so as to meet their essential requirements.

Design/methodology/approach

Market time is used as a representation of all the losses, which affect incurred equipment effectiveness. Based on a comprehensive scheme for loss analysis within market time, the concept of Integrated Equipment Effectiveness (IEE) is developed. Multiple case studies including three different cases within one large Asian steel making company were developed to assess the proposed model.

Findings

The case study reveals the importance of the new scheme for loss analysis in the capital‐intensive industry. IEE provides a whole perspective on effectiveness based on loading, capital and market features.

Practical implications

IEE monitors manufacturing process to utilise equipment effectively as much as possible and also measures the equipment effectiveness for full process cycle in order to respond to the market. It provides a sound perspective on improvement to the capital‐intensive industry.

Originality/value

The paper provides information on a new model to more accurate estimation of equipment effectiveness in the capital‐intensive industry. It helps to optimise resource allocation and make better strategic decisions. The model may be applied as a benchmark to achieve world‐class standard.

Abstract

Purpose

The steel industry is a capital‐intensive industry and equipment utilisation as effectively as possible is of high priority. One of the key difficulties in the steel industry is the need to synchronise several processes to create a flow through every machine and plant. This paper aims to introduce the concept of integrated equipment effectiveness (IEE), which is a new approach for overall equipment effectiveness (OEE) measurement in three elements, consisting of “OEE loading‐based”, “OEE capital‐based”, and “OEE market‐based” so as to meet these essential requirements.

Design/methodology/approach

Based on a comprehensive scheme for loss analysis, the concept of integrated equipment effectiveness is developed. The case study is conducted in the factory of one large Asian steel‐making company in order to examine the proposed model.

Findings

The case study reveals the importance of the new scheme for loss analysis in a steel‐making plant. IEE gives managers of steel plants a whole perspective on effectiveness. It also indicates the level of synchronisation of a specific machine for making steel within an entire organisation.

Practical implications

IEE monitors the manufacturing process to utilise equipment effectively as much as possible and also measures equipment effectiveness for the full process cycle in order to respond to the market. IEE makes communication easier and more efficient. It provides a sound perspective on improvement in steel making and also can be used as a benchmark.

Originality/value

The paper provides information on a new method for precise estimation of equipment effectiveness in a steel‐making plant. It helps in optimising resource allocation and in improving strategic decision‐making.

Abstract

Purpose

Continuous manufacturing systems used within the steel industry involve different machines and processes that are arranged in a sequence of operations in order to manufacture the products. The steel industry is generally a capital‐intensive industry and, because of high capital investment, the utilisation of equipment as effectively as possible is of high priority. This paper seeks to illustrate a new method, overall equipment effectiveness market‐based (OEE‐MB) for the precise calculation of equipment effectiveness for full process cycle in order to respond to the steel market.

Design/methodology/approach

A refinement of the existing concept of OEE is developed based on a new scheme for loss analysis within market time. The paper illustrates the concept with a case study based on compact strip manufacturing processes within the steel industry.

Findings

While the results for OEE by ignoring a considerable amount of possible hidden losses might be satisfying, the OEE‐MB report shows potential room for improvement. It reflects changes in both the internal and external market for the steel industry, and therefore provides a tool not only for monitoring but also for managing improvement.

Practical implications

OEE‐MB is an applicable method for the precise calculation of equipment effectiveness that provides a sound perspective on improvement of steel plants by taking into consideration all losses within market time for meeting both internal and external demands.

Originality/value

OEE‐MB monitors production and measures the equipment effectiveness for full process cycle in order to meet the market. It makes communication more efficient and easier within the steel industry and may be used as a benchmark to achieve world‐class standard.

Abstract

Purpose

The purpose of this paper is to provide the foundational economics, both in theory and practice, to describe the current competitive and operational market dynamics of the blood service industry in the United States of America.

Design/methodology/approach

The paper applies the dominant firm-competitive fringe model to describe how pricing is determined within the blood service industry, with particular focus on the nonprofit business model. The research also describes the role of government as one of the major determinants of pricing through regulatory demands.

Findings

The longstanding, free-market based economic foundations of the blood service industry have proven to be adequate in meeting the blood needs of the United States (US). Though there are clear market inefficiencies associated with the dominant firm model, none of the proposed solutions target the contractual and resulting pricing inefficiencies that persist because of the market structure.

Originality/value

In order to add value to the blood industry professionals, it is imperative to provide the foundational economics driving the current macro-level blood industry of the US.

Abstract

Purpose

This paper aims to review national aeronautics and space administration (NASA’s) broad investments in electrified aircraft propulsion (EAP). NASA investments are guided by an assessment of potential market impacts, technical key performance parameters, and technology readiness attained through a combination of studies, enabling fundamental research and flight research.

Design/methodology/approach

The impact of EAP varies by market and NASA is considering three markets as follows: national/international, on-demand mobility and short-haul regional air transport. Technical advances in key areas have been made that indicate EAP is a viable technology. Flight research is underway to demonstrate integrated solutions and inform standards and certification processes.

Findings

A key finding is that sufficient technical advances in key areas have been made, which indicate EAP is a viable technology for aircraft. Significant progress has been made to reduce EAP adoption barriers and further work is needed to transition the technology to a commercial product and improve the technology, so it is applicable to large transonic aircraft.

Practical implications

Significant progress has been made to reduce EAP adoption barriers and further work is needed to transition the technology to a commercial product and improve the technology, so it is applicable to large transonic aircraft.

Originality/value

This paper will review the activities of the hybrid gas-electric subproject of the Advanced Air Transport Technology Project, the Revolutionary Vertical Lift Technology Project and the X-57 Flight Demonstration Project, and discuss the potential EAP benefits for commercial and military applications. This paper focuses on the vehicle-related activities, however, there are related NASA activities in air space management and vehicle autonomy activities, as well as a breakthrough technology project called the Convergent Aeronautics Solutions Project. The target audience is people interested in EAP.

Abstract

Purpose

The purpose of this paper is to contest Edwards et al.’s (2002) findings that resistance to the introduction of double-entry bookkeeping and the form that it took when implemented by the British Government in the mid-nineteenth century was the result of ideological conflict between the privileged landed aristocracy and the rising merchant middle class.

Design/methodology/approach

The study draws upon a collection of documents preserved as part of the Grigg Family Papers located in London and the Thomson Papers held in the Mitchell Library in Sydney. It also draws on evidence contained within the British National Archive, the National Maritime Museum and British Parliamentary Papers which has been overlooked by previous studies of the introduction of DEB.

Findings

Conflict and delays in the adoption of double-entry bookkeeping were not primarily the product of “ideological” differences between the influential classes. Instead, this study finds that conflict was the result of a complex amalgam of class interests, ideology, personal antipathy, professional intolerance and ambition. Newly discovered evidence recognises the critical, largely forgotten, work of John Deas Thomson in developing a double-entry bookkeeping system for the Royal Navy and the importance of Sir James Graham’s determination that matters of economy would be emphasised in the Navy’s accounting.

Originality/value

This study establishes that crucial to the ultimate implementation of double-entry bookkeeping was the passionate, determined support of influential champions with strong liberal beliefs, most especially John Deas Thomson and Sir James Graham. Prominence was given to economy in government.

Abstract

Purpose

This research article presents an exploratory case study of the sociotechnical landscape of BookTok, and how young people use it to connect with others around the books they love, or those they love to hate. By observing the interplay between young people, books, and the technology (TikTok) that connects them, this study aims to explore how blending analog and digital media tools makes reading social and fun.

Design/methodology/approach

The authors selected three bestsellers available in English and Danish, and BookTokers who made related videos. This study used a qualitative, ethnographic (Pink, 2021) approach to explore interactions on the app. Inductive coding (Saldaña, 2021) helped the authors identify themes, and connect to areas of inquiry.

Findings

During the pandemic, TikTok and BookTok offered young people opportunities for reading engagement in social, bookish communities by using technology to promote reading in print. In doing so, their actions made reading and being a reader highly entertaining.

Research limitations/implications

As an exploratory case study, this research is not generalizable. But the findings will apply to future work on reading, publishing, and connected learning in a sociotechnical landscape.

Practical implications

BookTok connects print and digital formats, offering innovative possibilities for young people’s connected learning and reading promotion in schools and libraries.

Originality/value

Because TikTok is a relatively new tool, and its sub-community BookTok became popular during the COVID-19 pandemic, research on this topic is still in its earliest stages.
