Abstract

Purpose

The purpose of this paper is to provide a knowledge-enabled digital twin for smart design (KDT-SD) of aircraft assembly line (AAL) to enhance the AAL efficiency, performance and visibility. Modern AALs usually need to have capabilities such as digital-physical interaction and self-evaluation that brings significant challenges to traditional design method for AAL. The digital twin (DT) combining with reusable knowledge, as the key technologies in this framework, is introduced to promote the design process by configuring, understanding and evaluating design scheme.

Design/methodology/approach

The proposed KDT-SD framework is designed with the introduction of DT and knowledge. First, dynamic design knowledge library (DDK-Lib) is established which could support the various activities of DT in the entire design process. Then, the knowledge-driven digital AAL modeling method is proposed. At last, knowledge-based smart evaluation is used to understand and identify the design flaws, which could further improvement of the design scheme.

Findings

By means of the KDT-SD framework proposed, it is possible to apply DT to reduce the complexity and discover design flaws in AAL design. Moreover, the knowledge equips DT with the capacities of rapid modeling and smart evaluation that improve design efficiency and quality.

Originality/value

The proposed KDT-SD framework can provide efficient design of AAL and evaluate the design performance in advance so that the feasibility of design scheme can be improved as much as possible.

Abstract

Purpose

This paper aims to solve the facility location problem of mobility industry call centers comprehensively, considering both investment efficiency and long-term development efficiency.

Design/methodology/approach

In this paper, a two-phase decision-making approach within a multi-criteria decision-making (MCDM) framework has been proposed to help select optimal locations among various alternate locations. Both quantitative and qualitative information is collected and processed based on fuzzy set theory and fuzzy analytic hierarchy process. Then the fuzzy technique for order preference by similarity to an ideal solution method is incorporated in the framework to assess the overall feasibility of all alternates.

Findings

A real case of a mobility giant in China is applied to verify the effectiveness of the proposed framework. Sensitivity analysis also proves the robustness of the framework.

Originality/value

This two-phase MCDM framework allows the mobility industry call center location to be selected considering economic, human resource and sustainability elements comprehensively. The framework proposed in this paper might be applicable to other companies in the mobility industry when deciding optimal locations of call centers.

Abstract

International students make valuable educational and economic contributions in higher education institutions (HEIs) all across the world. They contribute to the diversity and add different perspective in classrooms. Attracting international students is one of the objectives of HEIs. International students being present all over the world access information about the university online. Hence, all the relevant information must be available on the HEI website. Institutions are also present on social media platforms for interaction purposes. The owned media, including website, social media, discussion forums, etc. of institutions must be regularly monitored and analysed. Equally important is to analyse what students are discussing online about institutions, that is, what are their sentiments. This chapter is an attempt to develop a guide for HEI to draw the interest of international students for an institution through web analytics and social listening. Web analytics will help in understanding the behaviour of the visitor to the HEI website. Key performance indicators that will help in achieve the objective of attracting international students will be identified. On the other hand, analysing social listening on different platforms will help in understanding international students’ perspectives towards a specific institution.

Abstract

Purpose

The purpose of this paper is to examine the extent to which corporate board characteristics influence the level of dividend pay-out ratio using a sample of UK small- and medium-sized enterprises from 2010 to 2013 listed on the Alternative Investment Market.

Design/methodology/approach

The data are analysed by employing multivariate regression techniques, including estimating fixed effects, lagged effects and two-stage least squares regressions.

Findings

The results show that board size, the frequency of board meetings, board gender diversity and audit committee size have a significant relationship with the level of dividend pay-out. Audit committee size and board size have a positive association with the level of dividend pay-out, whilst the frequency of board meetings and board gender diversity have a significant negative relationship with the level of dividend pay-out. By contrast, the findings suggest that board independence and CEO role duality do not have any significant effect on the level of dividend pay-out.

Originality/value

This is one of the first attempts at examining the relationship between corporate governance and dividend policy in the UK’s Alternative Investment Market, with the analysis distinctively informed by agency theoretical insights drawn from the outcome and substitution hypotheses.

Abstract

Purpose

The purpose of this paper is to study how local government policy influences the structure of Chinese pharmaceutical clusters during their industrial catch-up.

Design/methodology/approach

This paper applies a case study method by targeting pharmaceutical clusters in Tonghua, Taizhou, and Tianjin.

Findings

The varied structures of pharmaceutical clusters in China demonstrate local governments' efforts to utilize local resources accordingly. While the local governments in China introduce different policies to firms with different ownership in the process of constructing different cluster composition, all the local governments emphasize motivating the development of small- and middle-sized enterprises for cluster dynamics.

Practical implications

The local governments should try to reach a balance between short-term foundation and long-term competitiveness for industrial cluster development.

Originality/value

This paper provides the detailed analysis of local governments' influences on the formation of pharmaceutical clusters in China and helps to enrich the knowledge about how local government promotes industrial clusters to realize industrial catch-up through sectoral innovation system.

– The purpose of this paper is with robust control problem for event-triggered networked control systems (NCSs) with actuator failures and time-varying transmission delays.

Abstract

Purpose

The purpose of this paper is with robust control problem for event-triggered networked control systems (NCSs) with actuator failures and time-varying transmission delays.

Design/methodology/approach

A random sequence is introduced to describe the actuator faults, and a novel event-triggering communication scheme is adopted in the sensor-to-controller channel. By taking the event-triggered mechanism and network transmission delay into consideration, a delay system model is constructed.

Findings

Based on Lyapunov stability theory and free weighting matrix method, the feasibility criteria for co-designing both the controller gain and the trigger parameters are derived. Finally, a simulation example is exploited to demonstrate the effectiveness of the proposed linear matrix inequalities (LMIs) approach.

Originality/value

The introduced approach is interesting for NCSs with actuator failures and time-varying transmission delays.

Abstract

Purpose

Managers, investors and security analysts all pay special attention to the bottom line of income statements and they miss significant information included in accruals about the quality of earnings. A considerable portion of the earnings-quality literature examines the possibility of using the accruals to shift reported income among fiscal periods. One of the main roles of working-capital accruals is to adjust the recognition of cash flows. This paper aims to focus on earnings quality by examining the working-capital accruals quality using the method of Dechow and Dichev (2002).

Design/methodology/approach

Following the Dechow and Dichev (2002) model, the result of this paper shows that accrual quality is related to the absolute magnitude of accruals negatively. Also, the standard deviation of accruals, cash flows, sales and earnings is positively related to firm size. The result demonstrates and suggests that these observable firm characteristics can be used as instruments for measuring accrual quality. According to this framework, the author expects that the larger the unsigned abnormal accrual measure, the lower the earnings quality. Therefore, firms with low accrual quality have more accruals that are unrelated to cash flow realisations and so have more noise and less persistence in their earnings.

Findings

After examining earnings and accrual quality, this paper finds that average UK company behaviour was quite similar to the behaviour found earlier in the USA. This paper’s findings show that greater volatility of sales, cash flow, accruals and earnings results in a lower accrual quality. Without a doubt, some of the analysis in this paper, especially that using different equations to calculate working-capital accruals, leads us to a valuable improvement of the earlier studies.

Originality/value

In this paper, the author follows the method of Dechow and Dichev (2002) and define accrual quality as the extent to which accruals map into cash-flow insights based on the UK data. To find the quality of working-capital accruals, the author uses the standard deviation of the residuals as accrual quality that resulted from the author’s firm-specific OLS regressions of working-capital accruals based on last, current and one-year-ahead operating cash flow. Unlike prior research, to avoid a restriction to working-capital accruals, we use different equations to cover more items of working-capital accruals.
