Developing causal loop diagrams (CLDs) involves identifying stakeholders and endogenous variables and formulating variable causal relationships. Traditionally, the CLDs are developed mainly using a qualitative approach such as literature review, observations and interviews with stakeholders. However, modellers may question which stakeholders should be approached, whether the relevant variables are selected, and what to do when stakeholders perceive different variable relationships in the CLDs differently. Applying in a case study, this research proposes a multi-method approach by combining both quantitative and qualitative methods to select stakeholders, identify endogenous/exogenous variables, and develop the CLDs. The proposed quantitative method is expected to provide modellers with a justifiable stakeholder and variable selection process. The method also highlights possible hidden variables and relationships, which were further explored with a traditional qualitative approach.

PurposeThis paper aims to extend the customer complaint behaviour (CCB) knowledge by introducing a visual technique called customer complaint journey mapping as a means of capturing and understanding multi-faceted service failures involving multiple actors.Design/methodology/approachResearch participants were trained to record contemporaneous accounts of future dissatisfactory dining experiences. Minimising issues of memory recall whilst faithfully capturing complainants' raw emotions. These recordings formed the basis for follow up interviews, based on the critical incident technique.FindingsThe central finding of this paper was how other actors outside of the traditional service dyad played a dynamic role in co-creating a complainants' emotions and subsequent behaviours.Practical implicationsThe resulting customer complaint maps give deep insights into the complex social dynamics involved in CCB, providing a powerful tool for both researchers and staff responsible for recovery strategies.Originality/valueThe mapping framework provides an innovative means of capturing the actual complaint experiences of customers and the role of other actors, utilising a multi-method approach designed to address various limitations of existing CCB research.

Purpose This study aims to develop a method of segmenting markets by using the functional approach to attitudes. The adopted approach identifies and groups individuals based on what functions their held attitudes serve for them. Specific marketing mixes can, thus, be designed for each functional profile. Design/methodology/approach The multi-method approach adopted consists of a qualitative assessment of consumers’ attitudinal functions in the physical fitness context and the development of an instrument to identify the distribution of attitudinal function segments in the same context. Findings A valid and reliable instrument that can be used to segment a market based on functional profiles is developed. Practical implications The outlined method provides a method for practitioners to identify existing functional segments, thus creating marketing mixes based on these functional segments and, ultimately, maximizing the value created for each segment. Originality/value The value in this research lies in the integration of old concepts (functional approach and scale development) to solving a new problem. The functional approach reaches deep to determine “why attitudes are held” vs simply “what attitudes are held”. Operationalization difficulties led to the abandonment of the approach. This research, thus, contributes theoretically by actually operationalizing the functional approach via a scale development, and using the operationalized form as a new means for segmenting markets.

The multi-symplectic integrator, as a numerical integration approach with symmetry, is known to have the characteristic of preserving the qualitative features and geometric properties of certain systems. Using the multi-symplectic integrator, the numerical simulation of the Gaussian solitary wave propagation of the logarithmic Korteweg–de Vries (logarithmic-KdV) equation was investigated. The multi-symplectic formulation of the logarithmic-KdV equation was explored by introducing some intermediate variables. A fully implicit version of the centered box scheme was used to discretize the multi-symplectic equations. In addition, numerical experiments were carried out to show the conservative properties of the proposed scheme.

This article suggests a new methodological model for the study of hybrid media events with global appeal. This model, developed in the project on the 2015 <em>Charlie Hebdo</em> attacks in Paris, was created specifically for researching digital media—and in particular, Twitter. The article is structured as follows. Firstly, the methodological scope is discussed against the theoretical context, e.g. the theory of media events. In the theoretical discussion, special emphasis is given to i) disruptive, upsetting, or disintegrative media events and hybrid media events and ii) the conditions of today’s heterogeneous and globalised media communication landscape. Secondly, the article introduces a multi-method approach developed for the analysis of hybrid media events. In this model, computational social science—namely, automated content analysis (ACA) and social network analytics (SNA)—are combined with a qualitative approach—specifically, digital ethnography. The article outlines three key phases for research in which the interplay between quantitative and qualitative approaches is played out. In the first phase, preliminary digital ethnography is applied to provide the outline of the event. In the second phase, quantitative social network analytics are applied to construct the digital field for research. In this phase, it is necessary to map a) what is circulating on the websites and b) where this circulation takes place. The third and final phase applies a qualitative approach and digital ethnography to provide a more nuanced, in-depth interpretation of what (substance/content) is circulating and how this material connects with the ‘where’ in the digital landscape, hence constituting links and connections in the hybrid media landscape. In conclusion, the article reflects on how this multi-method approach contributes to understanding the workings of today’s hybrid media events: how they create and maintain symbolic battles over certain imagined constructs of social imaginaries of solidarity, belonging, contestation, and exclusion, a topic of core value for the theory of media events.

Purpose The purpose of this paper is to define the individual leadership competencies that are necessary to implement and sustain lean systems, based on a multi-method approach. Design/methodology/approach Data collection involved a literature review of lean competencies, interviews with four experts from the university and the industry, and an empirical survey answered by 91 respondents, who represented companies from several sectors. These techniques provided a mix of qualitative and quantitative data, which set a basis for identifying a list of competencies and discussing its validity. Findings In total, 16 lean leadership competencies were identified and validated, in terms of content validity, face validity, and predictive validity. Regarding this latter validity type, the survey results indicated that the competencies are positively associated with key operational performance indicators, organizational maturity level of lean, and leaders’ experience with lean systems. Practical implications The identified list of competencies may be a basis for the development of formal lean leadership development programs. The list may also support the design of tools for assessing the competencies of leaders in lean companies. Originality/value A list of 16 lean leadership competencies was developed based on a verifiable research method that used a mix of data collection techniques. This methodological approach is a distinctive characteristic in comparison with earlier studies, which did not include an empirical validation of the competencies.

Background Mentorship is used to ease entry to practice for new nursing graduates. However, little is known about the process of pairing with experienced nurses. The aim of this dissertation is to explore mentorship pairing processes for new nursing graduates and experienced nurses. Methods 1. A quality improvement project was conducted using organizational data to describe the impact of the New Graduate Guarantee program at The Ottawa Hospital from 2013 to 2018 on new graduate nurses and organizational outcomes. 2. An interpretive descriptive study was conducted to develop an in-depth understanding of mentorship pairing practices specific to nursing occurring in a clinical setting that will ultimately inform future mentorship pairing practices. 3. A systematic review was conducted to determine the effect of mentorship pairing processes on the mentoring relationship and outcomes at the level of the new nursing graduate, mentor and organization. Findings 1. From 2013 to 2017, 66 nurses were hired directly into operational vacancies and 579 new graduate nurses were paired with a mentor in the New Graduate Guarantee program. The two-year turnover rate for new graduates who participated in the New Graduate Guarantee program (21.5%, N=92/427) was lower than new graduate turnover rates reported in the literature. 2. Interviews with 13 new graduate nurses and 12 mentors revealed a lack of awareness of current nursing mentorship pairing processes. Six nurse leaders described pairing processes using third party pairing. Participants suggested preparation, socialization and self-selection are key components to consider for future practice. 3. Of 2583 citations screened, no studies evaluated the nursing mentorship pairing process. Research is required to determine effective mentorship pairing processes in nursing. Conclusion Although 579 nurses were hired through the New Graduate Guarantee nursing mentorship program, the 13 new graduates and 12 mentors interviewed were unaware of the process used for pairing. Furthermore, no studies have evaluated mentorship pairing processes. Ninety percent of new graduates hired participated in the New Graduate Guarantee program. Future research is required to trial pairing processes proposed by nurse leaders, new graduates and experienced nurses and to develop and validate tools to evaluate the outcomes of these pairings.

Annotation:

Increasing symptom awareness, encouraging help-seeking, and facilitating timely referral are key for improving cancer outcomes, particularly for cancers such as oesophageal and gastric (stomach), where five-year survival is less than 20%. In this research, I used multiple methods to explore factors that influence timely diagnosis of these cancers from a patient's perspective, with a particular focus on health literacy (accessing, understanding and using health information, and navigating healthcare systems). I started by exploring current knowledge in this field before conducting a systematic review investigating health literacy in the timely diagnosis of symptomatic cancer. Literature was searched from January 1990-May 2017 using six bibliographic databases. I screened 2304 titles/abstracts, assessed 26 full-text papers and included three, although they were methodologically weak, therefore limiting the conclusions. To examine pathways to diagnosis for oesophageal and gastric cancer, I conducted a questionnaire study of newly diagnosed patients across two hospitals in the East and North East of England. 127 participants were recruited (39.6% recruitment rate), aged 44-96 (median 71); 102 male (80%). Most had oesophageal cancer (n=102, 80%); 64 (50%) of the total cohort were late-stage at diagnosis. Common pre-diagnostic symptoms varied between cancers (oesophageal: difficulty swallowing (n=66, 65%), painful swallowing (n=55, 54%); gastric: fatigue/tiredness (n=20, 80%), weight loss (n=13, 52%)). The questionnaire included two domains (engagement, understanding) of the Health Literacy Questionnaire with participants demonstrating high health literacy (mean 4.18 and 4.28, score 1-5). The median time from noticing the trigger symptom (prompting help-seeking) to diagnosis was 81 days (IQR 45-137.5, n=107). Twenty-six participants were purposively sampled, from questionnaire respondents, for face-to-face interviews (aged 55-88, 18 male, 15 with oesophageal cancer). I undertook thematic analysis to explore participant accounts of their pathways to diagnosis, identifying that the symptom nature was important for appraisal, while health literacy ability influenced the health system interval. Descriptions of 'heartburn', 'reflux' and 'indigestion' differed between participants, suggesting these terms may introduce uncertainty in relation to symptom experience. This is the first study to explore the role of health literacy in the timely diagnosis of symptomatic cancer, and pathways to diagnosis for oesophageal and gastric cancers, from a patient's perspective. Findings provide important insights for the development of targeted awareness campaigns and strategies enhancing GP symptom exploration.

This study presents a critical investigation into the teaching of computer ethics. A qualitative pluralistic approach (a mixture of qualitative approaches) was used to investigate case studies of teaching computer ethics to university-level students from Bahrain. The main issue was that ethics to Arabs and Muslims is a matter of religion than a matter of philosophy whereas the dominant perception in the academic literature which discussed computer ethics teaching is that computer ethics is a form of practical philosophy and hence separate from religion. In order to shed light on this, the study investigated computer ethic’s perceptions and teaching practices which were occurring in universities in Bahrain. The study found that the issue was not a matter of perception but rather a matter of confusion and a misconception. Computer ethics was being confused with morality, religion, basic computer skills to name just a few. And such confusion was causing computer ethics to gradually disappear from the curriculum and become substituted with concepts which were not necessarily capable of building students’ ethical thinking. The study recommends that computer ethics teachers and policy makers from Bahrain distinguish computer ethics from religion, morality and from any other concept and identify it as an independent field of study, also teachers need to involve their students in social and ethical analysis of various kinds so that students understand that ethics is not a set of rules on what is forbidden and allowed aimed at providing straightforward answers to a given problem but rather ethics is a ‘cognitive tool’; a mechanism through which different competing ethical theories and standards are used to reflect on a given problem.

Annotation:

The literature of Integrated Water Resource Management argues collaborative watershed partnerships between state agencies and civil society are crucial for water governance. They bring stakeholders together to facilitate dialogue, reduce competition and negotiate on complex water related issues. However in newly independent states, like the Philippines, local state agencies are still struggling to adopt collaborative governance approaches that offer stronger stakeholder engagement, due to poorly implemented decentralizing policies, resource constraints and a lack of political will. Thus, the need to identify and explore alternative institutional arrangements that are capable and willing to support local government is the first step towards developing culturally appropriate and feasible solutions within the Philippine context. Using the Angat River Basin, located in Bulacan, Central Luzon, Philippines, as the focal area for investigation, this research presents a shift in thinking about mainstream watershed group-agency partnerships. As such, the research suggests that the Philippine Catholic Church, a key faith-based organization possesses the necessary skills, experience and trust to facilitate and support a potential partnership for the 63,000 hectare Angat River Basin. The findings from this research, which were collected using a qualitative multi-method approach, highlight how the Diocese of Malolos and the wider Philippine Catholic Church are not only actively responding to environmental advocacy and management, but that their strengths of transformational leadership, political acuity and moral authority compensate for the deficiencies of the local government.

La navegació en entorns desconeguts no estructurats és encara un problema obert en el camp de la robòtica. En aquesta tesi presentem una aproximació per a la navegació de robots basada en la combinació de navegació basada en landmarks, representació fuzzy d'angles i distàncies i una coordinació multiagent basada en un mecanisme de dites. L'objectiu de la tesi ha sigut desenvolupar un sistema de navegació robust amb sentit de l'orientació per a entorns no estructurats usant informació visual.

Per tal d'assolir aquest objectiu, hem centrat els nostres esforços en dues línies d'investigació: mètodes de navegació i construcció de mapes, i arquitectures de control per a robots autònoms.

Pel que fa als mètodes de navegació i construcció de mapes, hem extès el treball presentat per Prescott per tal que es pugui utilitzar amb informació fuzzy sobre la localitazció dels landmarks. A part d'aquesta extensió, tambés hem desenvolupat mètodes per a calcular objectius alternatius, necessaris quan el robot troba el camí bloquejat.

Pel que fa a l'arquitectura de control, hem proposat una arquitectura general que utilitza un mecanisme de dites per a coordinar un grup de sistemes que controlen el robot. Aquest mecanisme pot ser usat en diferents nivells de l'arquitectura. En el nostre cas l'hem usat per a coordinar els tres sistemes del robot (Navegació, Pilot i Visió), i tambés per a coordinar els agents que composen el sistema de Navegació. Usant aquest mecanisme de dites, l'acció que executa el robot és la més ben valorada en cada instant. D'aquesta manera, i si els agents fan les dites d'una manera racional, la dinàmica de les dites porta el robot a executar les accions necessàries per tal d'arribar a l'objectiu indicat. L'avantatge d'utilitzar aquest mecanisme és que no cal imposar una jerarquia entre els sistemes, com passa en l'arquitectura de subsumpció, si no que aquesta jerarquia canvia dinàmicament, depenent de la situació en què es troba el robot i les característiques de l'entorn.

Hem obtingut resultats satisfactoris, tant en simulació com en experimentació amb un robot real, que confirmen que el sistema de navegació és capaç de construir un mapa d'un entorn desconegut i utlitzar-lo per a moure el robot d'una posició inicial a un objectiu donat. L'experimentació tambés ha mostrat que el sistema de coordinació basat en dites que hem dissenyat produeix el comportament global d'executar les accions necessàries en cada instant per tal d'arribar a l'objectiu.
Navigation in unknown unstructured environments is still a difficult open problem in the field of robotics. In this PhD thesis we present a novel approach for robot navigation based on the combination of landmark-based navigation, fuzzy distances and angles representation and multiagent coordination based on a bidding mechanism. The objective has been to have a robust navigation system with orientation sense for unstructured environments using visual information.

To achieve such objective we have focused our efforts on two main threads: navigation and mapping methods, and control architectures for autonomous robots.

Regarding the navigation and mapping task, we have extended the work presented by Prescott, so that it can be used with fuzzy information about the locations of landmarks in the environment. Together with this extension, we have also developed methods to compute diverting targets, needed by the robot when it gets blocked.

Regarding the control architecture, we have proposed a general architecture that uses a bidding mechanism to coordinate a group of systems that control the robot. This mechanism can be used at different levels of the control architecture. In our case, we have used it to coordinate the three systems of the robot (Navigation, Pilot and Vision systems) and also to coordinate the agents that compose the Navigation system itself. Using this bidding mechanism the action actually being executed by the robot is the most valued one at each point in time, so, given that the agents bid rationally, the dynamics of the biddings would lead the robot to execute the necessary actions in order to reach a given target. The advantage of using such mechanism is that there is no need to create a hierarchy, such in the subsumption architecture, but it is dynamically changing depending on the specific situation of the robot and the characteristics of the environment.

We have obtained successful results, both on simulation and on real experimentation, showing that the mapping system is capable of building a map of an unknown environment and use this information to move the robot from a starting point to a given target. The experimentation also showed that the bidding mechanism we designed for controlling the robot produces the overall behavior of executing the proper action at each moment in order to reach the target.

Annotation:

This thesis uses a multi-method approach to examine the expectations of interpreting stakeholders in two different multilingual church organisations. Drawing on concepts from skopos theory and homiletics and on methodologies and findings from research on client expectations and interpreters’ perceptions of their work, it posits a four part correlational model to explain and predict how the skopos of an interpreted event will relate to stakeholders’ generic and event-specific expectations of interpreters. Results from a survey, interviews and participant observations all suggest that, contrary to existing theory, there is little evidence of a direct relationship between skopos and expectations of interpreters. On the contrary, it appears that organisational attitudes to interpreting are a much more salient factor in the conceptualisation of the work of interpreters and on the strategies they are expected to use to solve problems. The implications of these results for church interpreting research, theories of interpreting and interpreting practice are discussed, alongside the need to rethink and redesign the methods used in stakeholder expectations research, especially when this involves the use of surveys.

Background: Behaviour change, if maintained, can lead to significant health improvements. The aim of this thesis was to advance psychological theory of behaviour change maintenance and the design of behavioural interventions to improve health. This thesis used a novel multi-method approach to explore behaviour maintenance, with a particular focus on weight loss maintenance (WLM). Methods: A three stage, multi-method approach included: (1) A systematic review of behavioural theories to identify theoretical explanations for behaviour maintenance and to examine the relationships between these explanations; (2) An N-of-1 study of WLM assessing theoretical predictors of maintained behaviour based on the systematic theory review, which employed ecologic momentary assessment, wireless body scales, and activity monitors in 12 obese people who had lost at least 5% weight in the previous year, analysed through cross-correlations of time series; (3) Data-prompted semi-structured, longitudinal interviews with individuals who participated in the N-of-1 study to explore their experiences of WLM, prompted by personal data including summaries of N-of-1 data, pictures, notes and graphs, analysed using the Framework method. Findings: (1) Systematic review: out of 117 identified behaviour theories, 100 met the inclusion criteria. The main theoretical themes identified to underpin behaviour change maintenance included maintenance motives, self-regulation, habits, psychological resources and environmental/social influences; (2) N-of-1 study: for 12 participants a range of maintenance-related theoretical variables showed differential impact on ability to maintain weight, engage in physical activity and x follow a personal WLM plan. The combination of predicting variables that had significant impact on outcome variables was unique for each individual; (3) Data-prompted interviews: most of the theoretical explanations from the systematic theory review adequately accounted for participants’ experiences. Additional emergent themes included: competing goals, prioritising, and preparatory strategies that enhanced self-regulation. Using personal data summaries proved valuable in evoking narratives regarding unique experiences of WLM. Discussion: A range of theoretical explanations were identified and proved useful in explaining behaviour maintenance in the area of WLM. The main conclusion derived from the thesis is that behavioural interventions need to tap into relevant behavioural explanations and deliver intervention components in a timely manner to support individuals to maintain behaviour change. Interventions should include elements of choice and customisation and should be adaptable to personal needs. The main study strengths included employment of novel methods and technology. The main limitation included N-of-1 analytical challenges and scalability of the applied design. Future research should develop behaviour maintenance theory further and explore which combinations of WLM strategies, in which individuals, support effective WLM.

Annotation:

The Swedish-speaking minority in Finland, often described as an ‘elite minority’, holds a special position in the country. With linguistic rights protected by the constitution of Finland, Swedish-speakers, as a minority of only 5.3%, are often described in public discourse and in academic and statistical studies as happier, healthier and more well off economically than the Finnish-speaking majority. As such, the minority is a unique example of language minorities in Europe. Knowledge derived from qualitatively grounded studies on the topic is however lacking, meaning that there is a gap in understanding of the nature and complexity of the minority. Drawing on ethnographic research conducted in four different locations in Finland over a period of 12 months, this thesis provides a theoretically grounded and empirically informed rich account of the identifications and sites of belonging of this diverse minority. The thesis makes a contribution to theoretical, methodological and empirical research on the Swedish-speaking minority, debates around identity and belonging, and ethnographic methodological approaches. Making use of novel methodology in studying Swedish-speaking Finns, this thesis moves beyond generalisations and simplifications on its nature and character. Drawing on rich ethnographic empirical material, the thesis interrogates various aspects of the lived experience of Swedish-speaking Finns by combining the concepts of belonging and identification. Some of the issues explored are the way in which belonging can be regionally specific, how Swedish-speakers create Swedish-spaces, how language use is situational and variable and acts as a marker of identity, and finally how identifications and sites of belonging among the minority are extremely varied and complex. The thesis concludes that there are various sites of belonging and identification available to Swedish-speakers, and these need to be studied and considered in order to gain an accurate picture of the lived experience of the minority. It also argues that while identifications are based on collective imagery, this imagery can vary among Swedish-speakers and identifications are multiple and situational. Finally, while language is a key commonality for the minority, the meanings attached to it are not only concerned with ‘Finland Swedishness’, but connected to various other factors, such as the context a person grew up in and the region one lives in. The complex issues affecting the lived experience of Swedish-speaking Finns cannot be understood without the contribution of findings from qualitative research. This thesis therefore points towards a new kind of understanding of Swedish-speaking Finns, moving away from stereotypes and simplifications, shifting our gaze towards a richer perception of the minority.

This research explores two main problems encountered in multi-criterion inventory classification and ranking. The first problem is the integration of quantitative criteria with qualitative criteria. Most of the research in the field of multi-criterion inventory classification and ranking neglects qualitative criteria, as they are difficult to apply as compared with quantitative criteria. Even for the research that considers qualitative criteria for classification and ranking, the sensitivity of the qualitative criterion has not been explored. The second problem is the weight assignment to the criteria, both qualitative and quantitative, when integrated for classification and ranking of inventory items. Weight assigned to the criteria should represent relative importance of one criterion to another. Input of inventory managers are needed in assigning the weights.

An integrated inventory ranking and classification method is developed using the Analytic Hierarchy Process (AHP) and The Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method to rank and classify inventory items using quantitative and qualitative criteria. Classification and ranking of inventory items are industry-specific and differ from one industry to another. Classification and ranking can differ significantly between industries of the same type. Even the same type of industry can have a different philosophy and objective of inventory management, which influences the relative importance of the criteria and affects the classification and ranking. Classification and ranking are sensitive to the settings of the qualitative factor. Industries that gave higher priority to qualitative factors are affected more by change in the qualitative criterion's settings, as classification and ranking changes the most for them. Ranking is very sensitive and complex, as small change in any parameter is enough to change the rank without affecting the classification.

AbstractThe possible applications of small electric vehicles, i.e., electric cargo bikes and three- and four-wheeled L-class vehicles in transport, are discussed, and potential business models are presented. Moreover, transport-related potentials are analyzed. Therefore, we have utilized a multi-method approach: we conducted qualitative interviews with experts and professionals in the field of light and small electric vehicles and carried out quantitative analyses with the national household travel survey mobility in Germany 2017. Our results show that, theoretically, small electric vehicles could be used for 20–50% of private trips (depending on the model). On these trips, however, they would not only replace car trips, but also trips on public transport or by bicycle and on foot. In commercial transport, these vehicles are particularly suitable for service trips and some last-mile deliveries. If small electric vehicles were to replace a significant share of the transport volumes of motorized passenger and commercial transport, they could contribute to climate protection.

Abstract A qualitative reasoning approach is presented for decision support. This approach is initiated with the generation and normalization of a qualitative model including relationship matrix, importance weightings, control limits for decision variables, and specification limits for performance attributes. An extensive Simplex method is then utilized for mapping the global feasibility of the decision problem. Finally, the approach interprets and simplifies the results from the multi-dimensional feasibility space back to the qualitative model. The paper also presents application of the approach to process tuning of multilayer sheet extrusion and concept development of a 2nd generation reusable launch vehicle to orbit. The results indicate that the developed approach is a viable alternative to currently practiced decision analysis methods. Specifically, the approach uses: 1) tightened specification limits rather than a weighted multi-attribute objective relationship, 2) determines global system feasibility from active constraints rather than local parametric optimization, and 3) establishes correlations based on dynamic Pareto-optimal frontiers rather than manual estimations. While the approach is potentially useful, further research is required to extend the methods to non-linear, stochastic, and uncharacterized engineering systems.

Abstract Plant layout deals with selection of the most effective arrangement of facilities or departments to achieve the best utilization of the available resources to produce a product. The plant layout problem is of great interest to both scholars and practitioners. Historically, two basic criteria have been most commonly used to generate an optimum layout. These two criterions are quantitative and qualitative. In this study an approach is introduced as a heuristic technique for combining the quantitative and qualitative aspects of the facility layout. The two objectives which may be contradicting, are minimizing material handling costs and maximizing a closeness rating measure. Assuming that the decision-maker is capable of responding to a paired comparison of alternatives, this algorithm is developed to, iteratively, reduce the feasible space of the weighting factor, which combines the two objectives. The algorithm terminates when the predetermined bounds on the weighing factor are reached. A graphical method is presented to help analyze the sensitivity of the optimum layout into small variations in the estimated value of the decision-maker’s preferred weight. The proposed approach has been applied in a case study, which is an exhaust system factory (Engineering Company for Manufacturing Exhaust Systems) located in the 6th. October City. This factory was founded as a small workshop for producing hand-made mufflers to meet the needs of the local automotive repair shops. In order to satisfy the needs of assembly plants of exhaust systems, a new location in the 6th. October City has been chosen, modern machinery supplied and scientific techniques followed to accomplish optimum layout. By applying this approach the best layout can be generated. In this layout warehouses were rearranged and a reduction the total material handling costs of 32% has been achieved.

Most of the algorithmic engineering design optimisation approaches reported in the literature aims to find the best set of solutions within a quantitative (QT) search space of the given problem while ignoring related qualitative (QL) issues. These QL issues can be very important and by ignoring them in the optimisation search, can have expensive consequences especially for real world problems. This paper presents a new integrated design optimisation approach for QT and QL search space. The proposed solution approach is based on design of experiment methods and fuzzy logic principles for building the required QL models, and evolutionary multi-objective optimisation technique for solving the design problem. The proposed technique was applied to a two objectives rod rolling problem. The results obtained demonstrate that the proposed solution approach can be used to solve real world problems taking into account the related QL evaluation of the design problem.

Reinforcement learning (RL) agents have been deployed in complex environments where interactions are costly, and learning is usually slow. One prominent task in these settings is to reuse interactions performed by other agents to accelerate the learning process. Causal inference provides a family of methods to infer the effects of actions from a combination of data and qualitative assumptions about the underlying environment. Despite its success of transferring invariant knowledge across domains in the empirical sciences, causal inference has not been fully realized in the context of transfer learning in interactive domains. In this paper, we use causal inference as a basis to support a principled and more robust transfer of knowledge in RL settings. In particular, we tackle the problem of transferring knowledge across bandit agents in settings where causal effects cannot be identified by do-calculus [Pearl, 2000] and standard learning techniques. Our new identification strategy combines two steps -- first, deriving bounds over the arm’s distribution based on structural knowledge; second, incorporating these bounds in a dynamic allocation procedure so as to guide the search towards more promising actions. We formally prove that our strategy dominates previously known algorithms and achieves orders of magnitude faster convergence rates than these algorithms. Finally, we perform simulations and empirically demonstrate that our strategy is consistently more efficient than the current (non-causal) state-of-the-art methods

The main objective of qualitative research is to analyze the behavior of the trajectories of a dynamic system to verify whether it corresponds to the set of constraints characterizing the property. We use an approach to study binary dynamic systems on a finite time interval based on the author's method of Boolean constraints. Based on this method, the Boolean model of the properties of a binary dynamic system is written in the language of Boolean equations or Boolean formulas with quantifiers. Thus, the verification of various dynamical properties is reduced to solving the problems of Boolean constraints satisfiability or the validity of a quantified Boolean formula using efficient SAT or TQBF solvers. The high computational complexity of these problems requires the development of software and tools for their parallel and distributed solving and ensuring transparent end-user access to highperformance computing environments based on a service-oriented approach. This paper represents the architecture and functionality of a new instrumental system that automates the creation of a distributed application for solving the considered class of problems based on the microservice approach and multi-agent technology.

Many challenging fluid-structure interaction problems in nuclear engineering remain unresolved because current CFD methodologies are unable to manage the number of computational cells needed and/or the difficulties associated with meshing changing geometries. One of the most promising recent methodologies for fluid dynamics modeling is the lattice-Boltzmann method — an approach that offers significant advantages over classical CFD methodologies by 1) greatly reducing meshing requirements, 2) offering great scalability, and 3) through relative ease of code parallelization. While LBM often requires increased numerical effort compared to other methods, this can be dramatically reduced by combining LBM with Adaptive Mesh Refinement (LB-AMR). This study describes an ongoing collaboration investigating nuclear fuel-assembly spacer grid performance. The LB-AMR method, used to simulate the flow field around a specific spacer grid design, is capable of describing turbulent flows for high Reynolds numbers, revealing rich flow dynamics in good qualitative agreement with experimental results.

This paper presents a case study in selecting the best location for a Floating Storage and Regasification Unit (FSRU) in Bali. FSRU is an alternative to replace a conventional shore LNG terminal. The selection involves several criteria/attributes that can be grouped into two general attributes, namely qualitative and quantitative attribute. Multiple Criteria Decision Making (MCDM) approach is utilized to solve the selection problem, considering the capability of this method in solving multi-criteria problem with mutual conflict. Qualitative criteria is evaluated using AHP method to calculate weight of each criteria, and decision matrix algorithm is then utilized to convert preference of stakeholders into, consecutively, probability assignment, total probability assignment and preference degree. Quantitative criteria are also converted into preference degree and after combining with the preference degree of qualitative attribute, entropy method is then used to rank the alternatives. Selected location would be the alternative having the highest entropy. Four alternatives are under consideration; Benoa, Celukan Bawang, Pemaron and Gilimanuk. This research found that Celukan Bawang is the best location for the FSRU.

Abstract The data-driven approach is emerging as a promising method for the topological design of the multiscale structure with greater efficiency. However, existing data-driven methods mostly focus on a single class of unit cells without considering multiple classes to accommodate spatially varying desired properties. The key challenge is the lack of inherent ordering or “distance” measure between different classes of unit cells in meeting a range of properties. To overcome this hurdle, we extend the newly developed latent-variable Gaussian process (LVGP) to creating multi-response LVGP (MRLVGP) for the unit cell libraries of metamaterials, taking both qualitative unit cell concepts and quantitative unit cell design variables as mixed-variable inputs. The MRLVGP embeds the mixed variables into a continuous design space based on their collective effect on the responses, providing substantial insights into the interplay between different geometrical classes and unit cell materials. With this model, we can easily obtain a continuous and differentiable transition between different unit cell concepts that can render gradient information for multiscale topology optimization. While the proposed approach has a broader impact on the concurrent topological and material design of engineered systems, we demonstrate its benefits through multiscale topology optimization with aperiodic unit cells. Design examples reveal that considering multiple unit cell types can lead to improved performance due to the consistent load-transferred paths for micro- and macrostructures.

The article describes a case study methodology that is applied in RAFAEL for the verification and validation (V&V) of complex and multi-disciplinary systems. Various methods of V&V are found within the nature and the type of the product. Some applications use methods that are prevalent in the electronics industry. There are other methods that are based on international standards such as V&V for airborne structures. Complex systems are characterized by a number of special issues which do not allow for a simple implementation of V&V mentioned above. The following issues are unique to complex systems: the design consists of multi-disciplinary subjects, the cost of the life cycle is high, it takes a long time for hardware production and for the completion of development, there is a demand for high reliability, the V&V process contains a multiplicity of parameters and the system has multiple interfaces. For systems of this nature there is no V&V process available in use and it is necessary to implement a tailored-made method. This method of V&V deals with the two main quantitative and qualitative questions of proof: (a) how does the system and sub-system behave under external environmental conditions?, (b) how does the system and sub-system functioning under the existence of differences between sub-systems and components which are supplied in the delivery stage of the life cycle (i.e. geometrical and performance tolerances, time depending parameters)? The new approach is to design a process of V&V in the early stages of the product life cycle. It is different from the conventional approach which performs the reliability tests at the completion of the product development via the approval examinations. The steps in building updated V&V process for complex system are: 1. Identification of the functionality specification of the system and deriving from it the V&V building blocks. 2. Breaking down the system into independent factors and connecting to each factor the relevant part of the physical structures. For each component in the structures it is necessary to identify its functionality and whether if the specification comply with demands. 3. Building computational, analytical and functional models which describe the system, sub-system and its components behavior and sensitivity analysis. 4. Experimental validation for individual sub-systems and components. The purposes are to verify reliability of the models, to validate the margin of safety needed and to find out the failure threshold. 5. Experimental validation at a higher level. The purposes of this stage are to examine the internal and external interfaces, to verify the approach of the separation of parameters and to validate the system functionality. This new approach will be demonstrated on an electromechanical system.

In this paper the complex two-phase flow during oil-jet impingement on a rotating spur gear is investigated using the meshless Smoothed Particle Hydrodynamics (SPH) method. A comparison of single-phase SPH to multi-phase SPH simulation and the application of the Volume of Fluid method on the basis of a two-dimensional setup is drawn. The results of the different approaches are compared regarding the predicted flow phenomenology and computational effort. It is shown that the application of single-phase SPH is justified and that this approach is superior in computational time, enabling faster simulations. In a next step, a three-dimensional single-phase SPH setup is exploited to predict the flow phenomena during the impingement of an oil-jet on a spur gear for various jet inclination angles. Thereby, a significant effect of the inclination angle on the oil spreading and splashing process is revealed. Finally, a qualitative comparison to an experimental high-speed image shows good accordance.

Why do some fuel protests in Nigeria lead to a response from government, but others are barely noticed? What are the politics behind government response and who are the winners and losers? Using a multi-method approach, this study focuses on the period between 2007 and 2017 to investigate the dynamics of fuel protest in Nigeria to ask how, and under which conditions, struggles over energy access in Nigeria produce accountability and empowerment. The findings suggest that accountability and empowerment outcomes of the struggles over fuel access in Nigeria are severely limited by the very conditions that define the state as fragile: weak institutions, elite capture, widespread corruption, and a citizenry that is protest-fatigued and disempowered. This could be true of other fragile and conflict-affected settings. Therefore, frameworks that open up the civic space for dialogues between the government and citizens may produce better outcomes than protests.
