Sequence planning for human and robot cooperative assembly of large space truss structures
Authors: Guo Jifeng , Bai Chengchao , Chen Cheng 
Published: September 2017

Purpose
In the future, large space truss structures will be likely to require on-orbit assembly. One of the several proposed methods includes cooperative assembly performed by pressure-suited astronauts during extravehicular activity (EVA) and space robots. An intelligent planning method was presented to generate optimal assembly tasks.

Design/methodology/approach
Firstly, the inherent hierarchical nature of truss structures allows assembly sequences to be considered from strut level and structural volume element (SVE) level. Then, a serial assembly strategy in human-robot environment was applied. Furthermore, a two-level planning algorithm was presented. At the first-level planning, one ant colony algorithm for assembly sequence planning was improved to adopt assembly direction and time as heuristic information and did not consider assembly tasks. And, at the second-level planning, another novel colony algorithm for assembly task planning mainly considered results of the first-level planning, human-robot interactive information, serial assembly strategy and assembly task distributions.

Findings
The proposed two-level planning algorithm is very effective for solving the human and robot cooperative assembly of large space truss structures.

Research limitations/implications
In this paper, the case study is based on the following assumptions: each tetrahedron is assembled by two astronauts; each pentahedron is assembled by three astronauts.

Practical implications
A case illustrates the results of the two-level planning. From this case study, because of geometrical symmetry nature of large space truss structures, the optimal assembly sequences are not only one.

Originality/value
The improved ant colony algorithm can deal with the assembly sequence and task planning in human-robot environment more effectively.
An innovative method for exhaust gases toxicity evaluation in the miniature turbojet engine
Authors: Gawron Bartosz , Białecki Tomasz , Janicka Anna , Górniak Aleksander , Zawiślak Maciej 
Published: September 2017

Purpose
The purpose of this paper is to present an assessment method of the toxicity emission evaluation during combustion in the miniature turbojet engine.

Design/methodology/approach
A small-scale turbojet engine was used for the research because measurements on real aircraft turbines are complex and expensive. The experiment was performed in accordance with innovative BAT – CELL Bio – Ambient Cell method which consists of determination of virtual toxic impact of the gas mixture on the living cells; it is therefore a direct method. The most significant innovation of this method is that, during the test, which consists of exposing the cells to the gas mixture, the cells are deprived of culture fluid.

Findings
The preliminary analysis shows that the method used here allows to determine the virtual impact of the gases on the human respiratory system and skin. It could be useful in defining the arduousness of an airport. The obtained results show that both of exhaust gases represent similar toxicity.

Practical implications
The new in vitro method allows to determine the virtual impact of the gases on the human respiratory system and skin. Significant potential for further research not only on the miniaturised engines, but also in the case of real objects, as this method does not have to be performed in a laboratory.

Originality/value
The work presents potential application of the innovatory method for exhaust gases toxicity evaluation in jet engines, which could be useful in defining the arduousness of an airport.
Iron loss research of amorphous alloy motor by considering the influences of solidifying and annealing on stator core
Authors: Zhu Longfei , Tong Wenming , Han Xueyan , Zhu Jianguo 
Published: September 2017

Purpose
The specific iron losses of amorphous alloy material are extremely low compared with silicon steel material. The iron losses of motors may reduce by replacing the silicon steel core with an amorphous alloy core. However, one drawback of amorphous alloy material is that the specific iron losses will increase a lot after the motor manufacturing process. This paper aims to study the influences of interlaminar insulator solidifying and annealing on amorphous alloy material. The iron losses of motors made of amorphous alloy and baseline silicon steel sheets are compared and discussed.

Design/methodology/approach
This paper opted for an exploratory study using the experimental analysis and loss separation methods. Two amorphous alloy cores are produced and tested. The iron losses of motors made of amorphous alloy and silicon steel sheets are calculated and compared based on the measured specific iron losses. Three wound amorphous alloy core samples are made and measured. The iron losses are separated and compared by considering the manufacturing influences.

Findings
This paper provides empirical insights about what change is brought in amorphous alloy material after manufacturing. The results have shown that, for amorphous alloy cores without the annealing process, the loss increase caused by solidifying is mainly the eddy current loss, while it is mainly the hysteresis loss component for annealed amorphous alloy cores.

Originality/value
This paper presents for the first time the measured results of manufactured amorphous alloy cores. This paper fulfils the need to manufacture amorphous alloy motors properly for the producers.

Authors: Huangfu Youpeng , Wang Song , Wang Shuang , Li Hailin , Yuan Dongsheng , Wang Shuhong , Di Rienzo Luca 
Published: September 2017

Purpose
The purpose of this paper is to implement the macro-modeling and passivity enforcement for the equivalent high frequency circuit model of a single-phase winding for an alternating current (AC) three-phase motor. It provides a stable and strictly passive Foster-type circuit macro-model for the winding. Consequently, a stable circuit network is guaranteed when it is connected with an external passive circuit. The equivalent circuit is validated on a three-phase permanent magnet synchronous motor. Furthermore, the corresponding three-phase windings macro-model could be obtained accordingly.

Design/methodology/approach
The following techniques are used: the least square method, vector fitting method, the fast residue perturbation method, circuit synthesis, sequence quadratic programming method and simulated annealing method.

Findings
This work presents an effective approach to model an equivalent high frequency circuit macro-model for a single-phase winding. Simultaneously, both the characteristics of port passivity and component passivity are guaranteed.

Originality/value
This paper carries out both the port passivity and the component passivity enforcement for a single-phase winding of a motor during the macro-modeling procedure. This equivalent motor winding model can be applied to obtain the conducted electromagnetic interference and the overvoltage performance analysis for an adjustable speed motor drive system.
Event portfolios: asset value, risk and returns
Authors: Andersson Tommy Daniel , Getz Don , Gration David , Raciti Maria M. 
Published: September 2017

Purpose
The research question addressed is whether an event portfolio analysis rooted in financial portfolio theory can yield meaningful insights to complement two approaches to event portfolios. The first approach is extrinsic and rooted in economic impact analysis where events need to demonstrate a financial return on investment. In the second approach events are valued ally, with every event having inherent value and the entire portfolio being valued for its synergistic effects and contribution to social and cultural goals. The paper aims to discuss these issues.

Design/methodology/approach
Data from visitors to four events in the Sunshine Coast region of Australia are analyzed to illustrate key points, including the notion of “efficient frontier.”

Findings
Conceptual development includes an examination of extrinsic and intrinsic perspectives on portfolios, ways to define and measure value, returns, risk, and portfolio management strategies. In the conclusions a number of research questions are raised, and it is argued that the two approaches to value event portfolios can be combined.

Research limitations/implications
Only four events were studied, in one Australian local authority. The sample of residents who responded to a questionnaire was biased in terms of age, education and gender.

Social implications
Authorities funding events and developing event portfolios for multiple reasons can benefit from more rigorous analysis of the value created.

Originality/value
This analysis and conceptual development advances the discourse on portfolio theory applied to event management and event tourism.
The provenance of public management and its future: is public management here to stay?
Authors: Kisner Mirit , Vigoda-Gadot Eran 
Published: September 2017

PurposeThe purpose of this paper is to present the views of authors in regard to the provenance and future of PM and the advantages of using management science in administrative science. The authors point to the meaning of both sciences for government studies and to the use that both theoreticians and practitioners may gain from adequately balancing the disciplines for the public interest.Design/methodology/approachThe paper is based on a wide literature review of empirical and epistemological studies on new public management (NPM) and its evolvement across continents and cultures, and on a critical analysis of lessons learned from implementations of ideas and practices.FindingsThe authors identify the managerial reform in public administration as one of the more influential reforms of modern nations that cut across multiple policy areas, public agencies and cultures. The authors expect that public managers in the years to come are about to play a decisive role and be required to build collaborative capacity while governing creatively but without bending the rules. Ingenious civil servants are going to carry weight and devise new mechanisms for coping with prospective challenges; no doubt they will have to be savvier, more adept and open-minded than ever to be able to step up to the plate and assist governments to deal with impending crises.Originality/valueThe originality of this essay is reflected in the wide coverage of transitions in the managerial language of the discipline. Using manifold examples from different perspectives on NPM provides a unique and balanced look into what became the most influential reforms in public administration since the second half of the twentieth century, and is still alive and kicking.
Historic urban landscape: an approach for sustainable management in Cuenca (Ecuador)
Authors: Rey-Perez Julia , Siguencia Ávila María Eugenia 
Published: September 2017

Purpose
The purpose of this paper is to present a methodology developed on the basis of the Historic Urban Landscape (HUL) notion applied for the city of Cuenca in Ecuador. The identification of cultural values – among all the actors involved in the city – draws up a series of sustainable urban development strategies.

Design/methodology/approach
This methodology is based on the city analysis from the local community and multiple disciplines such as geomorphology, environment, urban planning, historic cartography, architecture, archaeology, anthropology, and economy. Further qualitative data collection methods included 16 workshops with 168 citizens, specific surveys, mapping, and on-site observations. The challenge of this methodology is not only its implementation in the world heritage city of Cuenca in Ecuador, but also the integration of the management of the historic centre within the overall city development plan.

Findings
The application of the HUL concept has allowed the identification of a series of strategies for the urban development where the points of view coming from different stakeholders were gathered. The project reveals the existence of values and attributes, so far overlooked in the actual heritage management system. In addition, a Geographic Information System database has been created with all the information related to Cuenca with the possibility of making it available for the community in the future.

Research limitations/implications
The project has been developed within one year with scarce economic resources: that is the reason why the planned activities took longer than expected.

Social implications
Social participation has played a key role in the development of the project.

Originality/value
This research process in Cuenca has led to its incorporation as a Latin-American pilot city for a programme developed by the World Heritage Institute of Training and Research for the Asia and the Pacific Region.

Authors: Awang-Hashim Rosna , Thaliah Rajaletchumi , Kaur Amrita 
Published: September 2017

PurposeThe cross-cultural significance of autonomy within self-determination theory is divisive on universal significance. This paper aims to report a sequential exploratory mixed methods study conducted to construct and validate a scale to investigate how, in Malaysian context, the construct of autonomy is conceptualized in comparison with the existing scale owing to cultural variation.Design/methodology/approachFocus group interviews identified dimensions of autonomy support that were specific to Malaysian culture and guided the development of the survey and construct validation was done using structure equation modeling.FindingsThe results show that the proposed scale has satisfactory psychometric properties, and the hypothesized model had a good fit to the data. The new scale produced four dimensions of teacher autonomy support, namely, responsible, approachable, shows respect and conveys confidence, with three items in each dimension. Malaysian secondary school students’ perception of autonomy support was found to be distinctive from the traditional measure.Originality/valueImplications for teachers are discussed for culturally meaningful interpretation of the autonomy construct for classroom teaching practices.
Identifying challenges facing manufacturing enterprises toward implementing sustainability in newly industrialized countries
Authors: Garbie Ibrahim 
Published: September 2017

Purpose
The purpose of this paper is to present and identify the challenges toward implementing sustainability strategies both strategic and tactical (STs) and performance measures (PMs) facing industrial organizations in newly industrialized countries.

Design/methodology/approach
Conducting a comprehensive survey on the published papers focused on the area of sustainability and/or sustainable development (S/SD) in manufacturing enterprises to identify the most common critical challenges. Setting with industrialists to determine which challenges the industrial organizations facing while implementing the S/SD strategies in terms of strategic, tactic and PMs. Using support logic techniques such as interpretive structural modeling (ISM) and interpretive ranking process (IRP) as modeling approaches to examine the contextual relationship among the STs and PMs individually “first phase,” to clarify and identify the most and least dominant factors, and to rank STs with respect to the PMs “second phase.”

Findings
The investigation shows that some challenges are more dominant and influential. Literacy and an awareness of sustainability, globalization and international issues and competitive strategies have emerged as the most dominant and key driving factors for STs in the ISM model, while the whole PMs are driven by remanufacturing and recycling factors in the ISM model. In addition, drivers and barriers to implementing S/SD challenges received the highest rank in the IRP model.

Research limitations/implications
Most of the STs and PMs were identified from academicians. Most of the manufacturing companies participated in the discussion; unfortunately, all are not familiar with the S/SD as a whole. They see to the S/SD from very narrow scope like climate change, environmental and energy issues only based on what they heard from media. Most of them are not fully interested to join with academicians to progress the work.

Practical implications
Most of the manufacturing companies are keen to investigate extremely sustainability challenges. Although this paper has a goal to provide a comprehensive framework to analyze, investigate and model sustainability challenges for industrial/manufacturing companies in different industrial sectors, most of the STs and PMs were identified from academicians. Most of the industrial/manufacturing companies participated in the discussion; unfortunately, all are not familiar with the S/SD as a whole. This study will help manufacturing/industrial companies to analyze and investigate the challenges toward implementing S/SD.

Originality/value
The originality of this paper is to identify the most common ST and PM challenges facing industrial organization toward implementing S/SD, modeling them into logical techniques and comparing between STs with respect to PMs.
Micro-hardness prediction of friction stir processed magnesium alloy via response surface methodology
Authors: Naser Ahmed , Darras Basil 
Published: September 2017

PurposeThe purpose of this paper is to present a model to predict the micro-hardness of friction stir processed (FSPed) AZ31B magnesium alloy using response surface methodology (RSM). Another objective is to identify process parameters and through-thickness position which will give higher micro-hardness values. Moreover, the study aims at defining the factor that exhibits the most effect on the micro-hardness. Friction stir processing (FSP) machine can then be fed with the optimized parameters to achieve desirable properties.Design/methodology/approachAn experimental setup was designed to conduct FSP. Several AZ31B magnesium samples were FSPed at different combinations of rotational and translational speeds. The micro-hardness of all the combinations of process parameters was measured at different through-thickness positions. This was followed by an investigation of the three factors on the resulting micro-hardness. RSM was then used to develop a model with three factors and three levels to predict the micro-hardness of FSPed AZ31 magnesium alloy within the covered range. The analyses of variance in addition to experimental verification were both used to validate the model. This was followed by an optimization of the response.FindingsThe model showed excellent capability of predicting the micro-hardness values as well as the optimum values of the three factors that would result in better micro-hardness. The model was able to capture the effects of rotational speed, translational speed, and through-thickness position. Results suggest that micro-hardness values were mostly sensitive to changes in tool rotational speed.Originality/valueFSP is considered to be one of the advanced microstructural modification techniques which is capable of enhancing the mechanical properties of light-weight alloys. However, the lack of accurate models which are capable of predicting the resulted properties from process parameters hinders the widespread utilization of this technique. At the same time, RSM is considered as a vital branch of experimental design due to its ability to develop new processes and optimize their performance. Hence, the developed model is very beneficial and is meant to save time and experimental effort toward effective use of FSP to get the desired/optimum micro-hardness distribution.
