Achieving higher supply chain performance via business process orientation
Authors: Miri-Lavassani Kayvan , Movahedi Bahar 
Published: March 2018

Purpose
The purpose of this paper is to explore the ways in which various dimensions of supply chain performance (SCP) can be improved through increased levels of process orientation across different core operational processes. This study aims to provide simple guidelines which are practical for business managers.

Design/methodology/approach
A conceptual model was developed based on the literature review and it was tested using an empirical study. Various factor analysis techniques are used to construct different components of the research model and test the hypotheses.

Findings
This study provides two main categories of findings. First, based on the exploratory analysis several constructs were developed. Second, using structural equation modeling the relationships among the constructs were examined. The findings suggest that managers need to take a targeted approach in increasing the levels of process orientation in order to achieve particular SCP goals.

Research limitations/implications
The result of this study is not indented to be generalized to all businesses; however, the methodology is flexible enough to be utilized in different industries and business scenarios.

Practical implications
The present study provides specific recommendations for business managers seeking to enhance various aspects of their organizational SCP. The research model can be used for future empirical as well as case studies.

Originality/value
This is the first comprehensive empirical study that separately measures business process orientation with respect to four core supply chain processes (planning, sourcing, making, and delivering) and assesses the impact of each core process on various dimensions of supply chain performance.
Absorptive capacity and ERP assimilation: the influence of company ownership
Authors: Nandi Madhavi Latha , Vakkayil Jacob 
Published: March 2018

PurposeThe purpose of this paper is to adopt two different perspectives of an organization’s absorptive capacity, namely, the asset perspective and the capability perspective, to examine its impact on enterprise resource planning (ERP) assimilation. While prior IT knowledge represents the asset perspective, organization’s combinative capabilities – formalization, cross-functional interfaces and connectedness – represent the capability perspective of absorptive capacity.Design/methodology/approachThe study develops a hypotheses-based theory of absorptive capacity. Data for hypotheses testing are collected from Indian organizations using a cross-sectional survey method. Partial least-squares technique is used to test the proposed hypotheses.FindingsThe results reaffirm earlier work showing the importance of connectedness and cross-functional interfaces in ERP assimilation; other two factors (prior IT knowledge and formalization) were not found to be positively related to ERP assimilation. To obtain more insights regarding the latter unexpected results, the study checked the interaction effect of the nature of company ownership (private or state-owned). The results pointed to the existence of a negative relationship between prior IT knowledge and ERP assimilation particularly in the case of private organizations compared to state-owned organizations.Originality/valuePrevious studies on ERP have predominantly examined the influence of absorptive capacity on ERP implementation outcomes at the user level. The present study focuses on absorptive capacity at the organizational level using two perspectives. By utilizing two perspectives on absorptive capacity, namely, the asset perspective and the capabilities perspective, it illustrates how different aspects of absorptive capacity can be brought to light while studying its impacts.

Authors: Abeygunasekera Ahangama Withanage Janitha Chandimali , Bandara Wasana , Wynn Moe , Yigitbasioglu Ogan 
Published: March 2018

Purpose
Multidisciplinary business process management (BPM) research can reap significant impact. We can particularly benefit from incorporating accounting concepts to address some of the key BPM challenges, such as value-creation and return on investment of BPM activities. However, research which addresses a relationship between BPM and accounting is scarce. The purpose of this paper is to provide a detailed synthesis of the current literature that has integrated accounting aspects with BPM. The authors profile and thematically describe existing research, and derive evidence-based directions to guide future research.

Design/methodology/approach
A multi-staged structured literature review approach to search for the two broad themes, accounting and BPM, supported by NVivo (to manage the papers and the coding and analysis processes) was designed and followed.

Findings
The paper confirms the dearth of work that ties the two disciplines, despite the synergetic multidisciplinary results that can be attained. Available literature is mostly from the management accounting perspective and relates to describing how performance management, in particular performance measurement, can be applicable to process improvement initiatives together with tools such as activity-based costing and the balanced scorecard. There is a lack of research that examines BPM in relation to any financial accounting perspectives (such as external reporting). Future research directions are proposed together with implications for practitioners with the findings of this structured literature review.

Research limitations/implications
The paper provides a detailed synthesis of the existing literature on the nexus between accounting and BPM. It summarizes the implications for practitioners and provides directions for future research by identifying key gaps and opportunities with a sound contextual basis for extension and new work.

Originality/value
Effective literature reviews create strong foundations for future research and accumulate the otherwise scattered knowledge into a single place. This is the first structured literature review that provides a detailed synthesis of the research that ties together the accounting and BPM disciplines, providing a basis for future research directions together with implications for practitioners.
Spatial correlation-aware statistical dual-threshold voltage design of template-based asynchronous circuits
Authors: Ghavami Behnam 
Published: March 2018

PurposePower consumption is a top priority in high-performance asynchronous circuit design today. The purpose of this study is to provide a spatial correlation-aware statistical dual-threshold voltage design method for low-power design of template-based asynchronous circuits.Design/methodology/approachIn this paper, the authors proposed a statistical dual-threshold voltage design of template-based asynchronous circuits considering process variations with spatial correlation. The utilized circuit model is an extended Timed Petri-Net which captures the dynamic behavior of the asynchronous circuit with statistical delay and power values. To have a more comprehensive framework, the authors model the spatial correlation information of the circuit. The authors applied a genetic optimization algorithm that uses a two-dimensional graph to calculate the power and performance of each threshold voltage assignment.FindingsExperimental results show that using this statistically aware optimization, leakage power of asynchronous circuits can be reduced up to 3X. The authors also show that the spatial correlation may lead to large errors if not being considered in the design of dual-threshold-voltage asynchronous circuits.Originality/valueThe proposed framework is the scheme giving a low-power design of asynchronous circuits compared to other schemes. The comparison exhibits that the proposed method has better results in terms of performance and power. To consider the process variations with spatial correlation, the authors apply the principle component analysis method to transform the correlated variables into uncorrelated ones.
A simple analysis of flying capacitor converter
Authors: Kadyrov Shirali , Skrzypacz Piotr Sebastian , Familiant Yakov Lvovich 
Published: March 2018

Purpose
The paper aims to emphasise how switched systems can be analysed with elementary techniques which require only undergraduate-level linear algebra and differential equations. It is also emphasised how math software can become useful for simplifying analytic complications.

Design/methodology/approach
The time domain voltage balance methodology is used for stability analysis. As for deriving formulas for the asymptotic average of both capacitor voltage and inductor current, a new simple analytic method is introduced.

Findings
It was shown analytically that the time average of capacitor voltage converges to half of the source voltage. A formula for the time average of the current of the inductor is also computed. As a by-product, it was discovered that the period of the current is half of the switching period. Numerical simulations are obtained to illustrate the accuracy of the results.

Research limitations/implications
Higher dimensional generalisations could become a bit complicated, as stability analysis of higher dimensional exponential matrices is not so easy to handle. On the other hand, the new discovery on the period of the current is more likely to give new insights into handling higher dimensional systems.

Practical implications
Analytical formulas are exact, and it helps in accurately modelling flying capacitor converts (FCCs) in practice.

Originality/value
FCC is well studied in engineering society. However, not much is done in obtaining closed form solutions using analysis. Also, math software is much used in computation of numerical results and obtaining simulations. In this paper, one more important aspect of math software is emphasised, namely, use symbolic and numeric computing environment Maple in analysis.
Statistical analysis of peak inrush current: a case study
Authors: Markiewicz Przemyslaw , Sikora Roman , Pabjanczyk Wieslawa 
Published: March 2018

PurposeThe purpose of this paper is to estimate that the start-up current parameters are stochastic or not. Electronic equipment in luminaries significantly improves their luminous efficiency, thereby increasing the energy efficiency of lighting installations. However, the use of electronics [e.g. electronic ballasts for discharge lamps or power supply units for light-emitting diode (LED) luminaries] may also cause some negative effects in lighting installations. One of such effects is large inrush current, which can greatly exceed the admissible line load and trigger the overcurrent protective devices.Design/methodology/approachThe paper presents results of laboratory tests together with their statistical analysis of the inrush currents of lighting luminaires. Three road luminaires build in different technologies of similar power have been selected for the study. The theoretical distributions described by the analytical formulas matched the empirical distributions by using the MATLAB’ Statistical Toolbox.FindingsAs parameters that characterize short-time overcurrent at start-up are the maximum value of overcurrent amplitude in start-up moment (IPIC), the duration of overcurrent in start-up moment (tPIC) and melting integral MI. The aim of this statistical analysis of the selected parameter is to provide an overcurrent mathematical description allowing to estimate the probability of occurrence of values. For lighting luminaire fitted with magnetic ballasts, the parameters analyzed will randomly vary with the moment of power on. For electronic ballasts, the occurrence of this phenomenon depends on the adopted construction solution.Practical implicationsThis will allow, for example, to estimate the probability of activation of protection device by comparing the value of the inrush current Joule’s integral MI with its value for the analyzed protection device. The proposed method may be useful for checking the selectivity of the protection devices in the lighting system.Originality/valueThe study enables application of a probabilistic model for analysis of inrush currents of lighting luminaire and predicting the possible consequences of their occurrence.
Numerical study of influential factors on partial discharges in HVDC XLPE cables
Authors: He Miao , Hao Miao , Chen George , Li Wenpeng , Zhang Chong , Chen Xin , Wang Haitian , Zhou Mingyu , Lei Xianzhang 
Published: March 2018

Purpose
For the dramatically developed high voltage direct current (HVDC) power transmission, HVDC cables play a vital role in the power transmission across seas and connections with renewable power sources. However, the condition monitoring of HVDC cables is still a challenging research topic. This paper aims to understand the influence of external factors, namely, current, cavity location and material properties, on partial discharge (PD) characteristics in HVDC cable in a numerical way referring to the refined Niemeyer’s model.

Design/methodology/approach
The influences of the three external factors are studied by a proposed numerical model for DC PDs based on the modification of a conventional PD model for AC voltage via a finite element analysis method.

Findings
The external factors can influence the discharge magnitude and discharge repetition rate via affecting the electrical conductivity of the material: DC PD is more frequent and with higher discharge magnitude when the cavity is closer to the conductor or the current through the conductor is higher. Both DC PD repetition rate and average discharge magnitude in long-term aged material are lower than virgin material. The effect of discharge on insulation degradation becomes decreasingly significant.

Research limitations/implications
The current work is based on the numerical modelling of DC PDs. Further experimental validations and comparisons are essential for improving the model.

Practical implications
The studies of the influence factors for PDs under HVDC voltage can benefit the research and practical power transmission on DC PDs, contributing the design and test of DC PDs in HVDC cables, exploring the understandings of the DC PDs’ mechanism.

Originality/value
This paper, to the best of author’s knowledge, first studies the influence factors on DC PDs based on the numerical modelling work.
Comparing unscented transformation and point estimate method for probabilistic power flow computation
Authors: Xiao Qing , Zhou Shaowu 
Published: March 2018

Purpose
Unscented transformation (UT) and point estimate method (PEM) are two efficient algorithms for probabilistic power flow (PPF) computation. This paper aims to show the relevance between UT and PEM and to derive a rule to determine the accuracy controlling parameters for UT method.

Design/methodology/approach
The authors derive the underlying sampling strategies of UT and PEM and check them in different probability spaces, where quadrature nodes are selected.

Findings
Gauss-type quadrature rule can be used to determine the accuracy controlling parameters of UT. If UT method and PEM select quadrature nodes in two probability spaces related by a linear transform, these two algorithms are equivalent.

Originality/value
It shows that UT method can be conveniently extended to (km + 1) scheme (k = 4; 6; : : : ) by Gauss-type quadrature rule.
Fast and high-precision calculation of earth return mutual impedance between conductors over a multilayered soil
Authors: Ma Junjie 
Published: March 2018

Purpose
Solutions for the earth return mutual impedance play an important role in analyzing couplings of multi-conductor systems. Generally, the mutual impedance is approximated by Pollaczek integrals. The purpose of this paper is devising fast algorithms for calculation of this kind of improper integrals and its applications.

Design/methodology/approach
According to singular points, the Pollaczek integral is divided into two parts: the finite integral and the infinite integral. The finite part is computed by combining an efficient Levin method, which is implemented with a Chebyshev differential matrix. By transforming the integration path, the tail integral is calculated with help of a transformed Clenshaw–Curtis quadrature rule.

Findings
Numerical tests show that this new method is robust to high oscillation and nearly singularities. Thus, it is suitable for evaluating Pollaczek integrals. Furthermore, compared with existing method, the presented algorithm gives high-order approaches for the earth return mutual impedance between conductors over a multilayered soil with wide ranges of parameters.

Originality/value
An efficient truncation strategy is proposed to accelerate numerical calculation of Pollaczek integral. Compared with existing algorithms, this method is easier to be applied to computation of similar improper integrals, such as Sommerfeld integral.
A methodology for the optimized design of power transformer insulation system
Authors: Rodriguez-Ignacio Hugo , Lopez-Fernandez Xose M. , Álvarez-Mariño Casimiro 
Published: March 2018

Purpose
The purpose of this paper is to present a methodology based on an optimizer linked with electric finite element method (FEM) for automating the optimized design of power transformer insulation system structures.

Design/methodology/approach
The proposed methodology combines two stages to obtain the optimized design of transformer insulation system structures. First, an analytical calculation is carried out with the optimizer to search a candidate solution. Then, the candidate solution is numerically checked in detail to validate its consistency. Otherwise, these two steps are iteratively repeated until the optimizer finds a candidate solution according to the objective function.

Findings
The solutions found applying the proposed methodology reduce the inter-electrode distances compared to those insulation designs referenced in the literature for the same value of safety margin.

Originality/value
The proposed methodology explores a wide range of insulation system structures in an automated way which is not possible to do with the classical trial-and-error approach based on personal expertise.
Comparison of facilities management in private domestic buildings among different elderly groups in Hong Kong
Authors: Leung Mei-yung , Famakin Ibukun Oluwadara , Ahmed Khursheed 
Published: March 2018

Purpose
Personal characteristics, such as age, marital status, education level and gender, vary among elderly residents in residential apartments. These characteristics may influence the elderly residents’ satisfaction with the facilities provided in their residential apartments. To ensure appropriate facilities management (FM) items are provided for the different categories of elderly people, it is necessary to understand their basic needs. Therefore, this paper aims to compare the satisfaction with FM items among elderly people with different personal characteristics in private domestic (PD) buildings.

Design/methodology/approach
A questionnaire survey was conducted among elderly people with different personal characteristics in PD buildings to collect information about their levels of satisfaction with FM items. A total of 41 FM items and four characteristics of the elderly, namely, age, gender, marital status and education, were identified in this study.

Findings
The result shows that satisfaction with natural daylight was significantly different among elderly people of different genders, while the one-way between-groups ANOVA indicate that satisfaction with the size of bedrooms, turning spaces at doors, temperature in bathrooms and/or toilets, colour, accessibility and ease of closing or opening the doors were significantly different among elderly people belonging to different age groups and of different marital status and education level.

Originality/value
Designers and private developers are therefore recommended to increase the sizes of bedrooms, install windows on opposite sides of walls in the flats and ensure there is an adequate light reflection ratio for wall and floor colours, to accommodate elderly people’s special characteristics.
Building design for people with dementia: a case study of a UK care home
Authors: Fisher Lee H. , Edwards David John , Pärn Erika Anneli , Aigbavboa Clinton Ohis 
Published: March 2018

Purpose
This paper aims to investigate the impact that building design has upon the quality of life for residents of a care home who have dementia. To present a balanced perspective, carers within the care home also participate in the research.

Design/methodology/approach
A case study methodological approach was adopted using one care home, ten residents and five staff as a sample frame. During interviews conducted, participants were asked semi-structured questions on how building design features impact upon the quality of life of residents. Questions posed focussed upon key design principles that emerged from a detailed review of extant literature.

Findings
Building design for people with dementia must consider a complex array of features to provide a safe and habitable living space for residents and family members who visit. This living space must also be suitably utilitarian and provide a workable environment for staff. Hence, an appropriate balance between these two competing requirements must be attained, and often a tailor-made solution is required that fits the individual’s level of dementia. Three prominent areas that study participants expressed a desire for were a safe environment; support for wayfinding, orientation and navigation; and access to nature and the outdoors.

Originality/value
The work reports upon the rarely discussed issue of building design for people with dementia and could be used by policymakers and construction firms to enhance their knowledge capabilities in this area. The research concludes with direction for future research which should seek to provide more evidence-based research vis-a-vis perception enquiry and extend this seminal work to a larger sample of care homes or people with dementia living at home.

Authors: Hassanain Mohammad A. , Garkuwa Jamilu A. , Sanni-Anibire Muizz O. 
Published: March 2018

PurposeThe purpose of this paper is to present the development and implementation of a qualitative, code-compliance framework for property managers of student housing facilities.Design/methodology/approachThe paper identified the fire safety code requirements for student housing facilities and arranged these requirements in the form of a checklist, which was further validated by professional experts. Additionally, the paper presented an IDEF0(Integrated Definition for Function Modeling) framework model that illustrates a stepwise process for the deployment of the checklist. A case study was conducted on three similar student housing facilities in a university campus to demonstrate the application of the framework. Furthermore, the findings from the case study were reported along with recommendations to improve the degree of compliance with the requirements of fire safety codes.FindingsThe developed framework was validated by professional experts and through a case study. Fire safety provisions were mostly found to be adequate in the case study building. The authors proposed several actions to improve the current status of fire safety in the building.Originality/valueThe paper serves to disseminate awareness about the occurrence of fires, their severe consequences and precautionary measures in student housing facilities. It also provides a standardized checklist for ease of use by property managers who may be unable to understand the technical terminologies found in fire safety codes and standards. Thus, the developed framework is of tangible value to property managers, building specialists and student housing administrators.
