This research focused on the development of a user centric framework for the interpretation of contextualised TV and video viewing experiences (UX). Methods to address content overload and provide better contextualisation when consuming video have been an area of academic discussion for almost 20 years (Burke, Felfernig, & Goker, 2011). However over the same period technical system design for video has actually moved away from attempts to model the nature of real viewing contexts. With now near ubiquitous access to video from a range of disparate devices the addition of contextualisation within video applications and devices represents an opportunity in terms of improving viewer UX. Three user studies were carried out to inform development of the framework and employed mixed method approaches. The first focused on understanding where video is watched and the contextual factors that defined those places as viewing situations. This study derived eight Archetype viewing situations and associated contextual cues. The second study measured viewing UX in context. Significant differences in subjective ratings for measured UX were found when viewing was compared within subjects across Viewing Archetype situations. A third study characterised viewing UX, identifying behavioural, environmental and technological factors which through observed frequency and duration were identified as indicative enablers and detractors in the creation of viewing UX. Concepts generated within the studies that related to viewing context identification and viewing UX classification through experiential factors were integrated into the framework. The framework provides a way through which to identify, describe and improve viewing UX across contexts. Additionally the framework was referenced to develop an exemplar system model for contextual adaptation in order to show its relevance to the generation of technical system design. Finally information for designers was created in the form of scenarios and suggestions for use in order to bring the framework to life as a resource for development teams.

Le raffinage a pour objet de transformer le pétrole brut en différents produits finis à des fins énergétiques on non. En Algérie, l'industrie du raffinage doit désormais s'adapter pour répondre à l'évolution de la demande, dans un contexte marqué par une forte volatilité des marchés pétroliers. Les méthodes de programmation linéaire sont fréquemment utilisées dans cette industrie afin d'optimiser le fonctionnement de cette industrie tant en terme de production que d'investissement. Dans cette recherche, nous sommes amenés à prendre en compte le caractère aléatoire de la demande locale de produits pétroliers ainsi que la volatilité des prix d’exportation sur les marchés internationaux. Ceci conduit à élaborer un modèle de programmation linéaire stochastique du raffinage à l’horizon 2030 en introduisant des aléas sur la demande et sur les prix des produits exportés. Les consommations futures en Algérie sont estimées à partir d'une approche économétrique. Les équilibres de long terme entre les prix du pétrole et des produits pétroliers sur les marchés internationaux sont estimés à partir d'une approche en terme de cointégration. La comparaison des résultats des modèles déterministes et de ceux obtenus avec les modèles stochastiques permet d'évaluer l'impact significatif de la variabilité de la consommation et des prix sur le sentier de développement du secteur du raffinage / The refining industry transforms the crude oil into various finished products (for energy purposes one not). In Algeria, the refining industry has to adapt itself to answer the evolution of the demand, in a context characterized by a high volatility of the oil markets. The linear programming methods are frequently used in this industry to optimize the production and the investment patterns of this industry. In this research, we take into account the random character of the domestic demand of petroleum products as well as the volatility of the export prices on the international markets. This leads to elaborate a stochastic linear programming model of the refining industry on the horizon 2030 by introducing changes on the demand and on the prices of the exported products. The future consumptions in Algeria are forecasted through an econometric model. The long-term equilibrium between oil prices and petroleum products on the international markets is also estimated through a cointegration approach. The comparison between the results of the deterministic model and the results of the stochastic model point out the significant impact of both the consumption variability and the price volatility on the refining industry

Manufacturing matters. It matters because of the economic contribution it provides in terms of wealth generation, employment and exports. The manufacturing industry in the United Kingdom can be strengthened. The opportunity for improvement includes closing the productivity gap between other countries, encouraging innovation and developing the skills of the workforce, in order to be globally competitive, drive growth and to help reduce the trade deficit. Critical to exploiting these opportunities, and to the success of the industry, is the adoption of best practice. Existing support for manufacturing improvement can be costly, difficult to access or dependent on input from external experts. This support therefore is not readily accessible to every manufacturing company. There are also a number of quality and performance awards available, however these are predominantly focused on recognising success rather than on how this success can be attained. This research fulfils the gap by providing widely accessible support for manufacturing companies that is focused on helping them to improve. The support provided helps companies to identify and adopt relevant best practices. This research work adapted a product evaluation framework to develop MX Start, a process that supports manufacturing companies to start their improvement journey towards manufacturing excellence. MX Start was developed following a review of the definition of Manufacturing Excellence, a needs assessment of the opportunity, analysis of best practice dissemination strategies, comparative analysis of existing tools and a review of effective self assessment and feedback principles. MX Start provides an easy to use, free of charge, web based system that facilitates manufacturing companies to start their excellence journey. It enables manufacturers to benchmark themselves against best practice in order to gain a greater understanding of what excellence entails, and to enable improvement areas to be identified. This is then supported with a report that helps companies to prioritise the improvement opportunities and provides feedback to then help them make these improvements. The combination of the free of charge, widely accessible, self-directed system that is solely concerned with supporting and encouraging companies to improve, is the basis of the innovation of this work. MX Start has demonstrated impact to the manufacturing industry through a pilot and on-going work with the Manufacturing Advisory Service (MAS). As part of the pilot, over two hundred companies used the process to conduct diagnostic activities to define areas for improvement, and identify where and how they could implement best practices. As a result, MAS in the West Midlands have adopted the tool and supported further developments of this research. This has increased the opportunity for MX Start to help companies progress on their excellence journey and therefore, help support the manufacturing industry to improve. An evaluation of MX Start by companies and manufacturing experts, found that the tool was easy to understand and use, and that it helped companies to identify, and be motivated, to make improvements. The web based system lends itself to further development. In addition to the assessment and report elements of MX Start, the website contains a resource library. The resources contain more information and guidance. The opportunity for the future is to expand this library and build a comprehensive database of support. This would increase the ability of MX Start to support manufacturers to exploit the improvement opportunities to strengthen the competitiveness of the manufacturing industry.

Dans l'industrie l'approche de gestion du cycle de vie du produit (PLM) a été considérée comme une solution essentielle pour améliorer la compétitivité des produits. Elle vise à fournir une plate-forme commune qui rassemble les différents systèmes de l'entreprise à chaque étape du cycle de vie du produit dans ou à travers les entreprises. Bien que les principaux éditeurs de logiciels fassent des efforts pour créer des outils offrant un ensemble complet et intégré de systèmes, la plupart d' entre eux n'intègrent pas l'ensemble des systèmes. Enfin, ils ne fournissent pas une intégration cohérente de l'ensemble du système d'information. Il en résulte une sorte de « tour de Babel », où chaque application est considérée comme une île au milieu de l'océan de l'information, gérée par de nombreuses parties prenantes dans une entreprise, ou même dans un réseau d'entreprises. L'hétérogénéité des parties prenantes augmente le problème d'interopérabilité. L'objectif de cette thèse est de traiter la question de l'interopérabilité sémantique, en proposant une méthode d'annotation sémantique formelle pour favoriser la compréhension mutuelle de la sémantique de l'information partagée et échangée dans un environnement PLM / In manufacturing enterprises the Product Lifecycle Management (PLM) approach has been considered as an essential solution for improving the product competitive ability. It aims at providing a shared platform that brings together different enterprise systems at each stage of a product life cycle in or across enterprises. Although the main software companies are making efforts to create tools for offering a complete and integrated set of systems, most of them have not implemented all of the systems. Finally, they do not provide a coherent integration of the entire information system. This results in a kind of "tower of Babel", where each application is considered as an island in the middle of the ocean of information, managed by many stakeholders in an enterprise, or even in a network of enterprises. The different peculiarities of those stakeholders are then over increasing the issue of interoperability. The objective of this thesis is to deal with the issue of semantic interoperability, by proposing a formal semantic annotation method to support the mutual understanding of the semantics inside the shared and exchanged information in a PLM environment

Lack of visibility of the assets in a product supply chain compromises attempts to optimise supply chain management. Increasing the visibility of these assets presents a relatively unexplored frontier in operations and supply where organisations can create competitive advantage through the opportunities asset visibility offer. This research aims at investigating the key capabilities of asset visibility specifically those associated with returnable transport assets that travel across supply chains carrying material and products e.g. cages, boxes, trays, trolleys and pallet bins. In addition, how these capabilities may influence supply chain visibility and firm performance in a way that might lead to sustainable competitive advantage is examined. To achieve these objectives, the research develops a two-stage model that is theoretically grounded in the extended resource-based view. Philosophically, the research adopts a critical realist approach using abductive logic. Methodologically, a sequential exploratory strategy for data collection is implemented. A qualitative, indepth site-based case study supported by field expert interviews was conducted as a pilot study. The pilot study findings refined the initial conceptual model derived from literature and informed the next stage of the research. The quantitative phase focused on refining the factors constituting asset visibility capabilities and then testing the relationship between these capabilities and supply chain visibility, performance and sustainable competitive advantage. Key findings are that asset visibility capabilities are shaped through three key capabilities: (1) an asset management capability formed by both core technological aspects related to tracking and tracing technology, and non-technological ones focusing on logistic-related capability; (2) a complementary technological capability comprising of IT infrastructure for supply chain integration; and (3) a complementary nontechnological capability represented through three sub-capabilities: (a) supply chain process integration; (b) focal firm-3PL relational orientation; and (c) internal firm integration. The research findings prove a positive relationship between asset visibility capabilities and supply chain visibility. In addition, a positive relationship between these capabilities and sustainable competitive advantage through the mediated effect of supply chain visibility and firm performance, is confirmed.

Nowadays, inspection process planning (IPP) for large volume metrology (LVM) attracts increasing attention in manufacturing and assembly industries such as aerospace and automotive, where large and complex assemblies and fabrications with complex surfaces are employed. Inspection is conventionally considered as a quality control manner. But there is changing shift to processes that are more related to the early design stage aiming to increase product performance and reduce costs by automation and elimination of rework. This is especially evident in the standardisation and implementation of Geometric Dimensioning and Tolerancing (GD&T) of new products and systems at the design stage. This study proposes a GD&T based systematic framework for the IPP of LVM systems within a digital environment. Orientating to solve the “what to measure” and “how to measure” problems in IPP, the prototype system has seven functional core modules including: tolerance feature analysis, instrument selection, inspection point selection, accessibility and visibility analysis, instrument setup and configuration, clustering analysis and measurement sequencing. An optimized inspection plan is output for the designer to evaluate the product design as well as for guiding the metrologist and process planner to conduct the inspection process. Heuristic rules, evolutionary algorithms and modern computational graphic techniques have been adopted to facilitate the supported functions. Coupled with state of art metrology systems, metrology and CAD software, the framework is able to work effectively and efficiently by means of incorporating international standards and industrial best practice. It is the first attempt to successfully minimise manual activities in the planning process for LVM systems, which results in improved efficiency, enhanced decision making and a better inspection plan overall. Two case studies have been conducted to validate the functionalities of the prototype system.

The introduction of standardized quality systems and their development into quality management systems offers the opportunity to evaluate the organizational quality of business entities, regardless of their industry. For professional purchasers it has become common practice to demand evidence of the successful application of a quality management system-a necessary step in the process of pre-qualifying potential suppliers. It has become common practice to have the introduction and operation of a quality management system as a minimum requirement for contract as part of a value chain of potential clients or contracting authorities as a future or continuous supplier or service provider. Moreover, this has to be approved. To do so, purchasers can perform supplier audits or ask for evidence provided by certificates. Typically, certificates stating conformity to the requirements of a quality management system are issued by professional audit service companies, so called certification bodies. This study helps to remedy the dearth of studies concerning the effectiveness of audits conducted by certification bodies. This qualitative study uses a limited number of case studies to analyse and assess the approaches and techniques used by auditors for certification or re-certification audits. Additionally, this study attempts to understand whether auditors involved have taken into account the paradigm change of the early 2000s. To this end, auditors involved in the case studies were interviewed. The interviews were dedicated to understanding the cognitive processes of data analysis and the resulting judgements which led to the issuance of certificates stating conformance to the relevant standards. The study was completed on quality management system audits founded on the ISO 9001:2008. This standard establishes the foundation for various further industry-dedicated standards, for example the IRIS or the ISO/TS 16949. Cases studies were performed out in small sized companies and recorded through audio tape recordings, as well by notes concerning auditors’ observed actions. These were transcribed and coded. Analysis of the data indicates that auditors have a detailed idea of what is to be found, regardless the type of business an auditee conducts and the aims of a company. The structure, policy, and individual processes of the audited company did not seem to be of interest. Additionally, audits were performed on the results of audited processes more so than on the progress of the process action and their input/output relation. The interviews shed light on auditors’ understandings of the underlying concepts of the ISO 9001:2008. The results show that the auditors examined still have problems with applying these concepts for their audit practices. Furthermore, the study shows the relationship between power and independence of auditors and their impact on effectiveness. Consequently, the study shows that a certificate issued by a professional audit service does not guarantee conformance to the ISO 9001:2008.

This thesis is an empirical investigation into the control mechanisms of headquarters (HQ) exercised over their subsidiaries and is conducted with the help of primary data collected from 147 Multinational Enterprises (MNEs) operating in the kingdom of Saudi Arabia (KSA). Following on from the literature review, this study proposed that the headquarters-subsidiary mechanisms could be linked to agency theory (with the 'classical' principal-agent relationship as its core) and to resource dependency theory (implying relations between the subsidiary and other partners based on interdependence). Our results show that the agency and resource dependency mechanisms are indeed used side by side and complementary to each other to exercise control. The Headquarters-subsidiary model used in this study has four components of control in it: personal centralised control (PCC), bureaucratic formalised control (BFC), output control (OUT) and informal control (INFO). These controls (as an agency mechanism) provide a solid platform on which other mechanisms can be built. The complementarities of these control mechanisms may be linked to earlier studies that show that successful organisations combine tight control with more open, informal and flexible information and communication exchanges. A focus that bends too much towards formal control or too much towards informal control may threaten a company's existence. Our research provides an empirical explanation on this premise. The study found that Anglo-Saxon countries heavily use impersonal types of control mechanisms, specifically bureaucratic formalised control and output control. Compared to the US, the level of control in Oriental subsidiaries is less; or, put differently, the latter enjoy a greater degree of autonomy than US subsidiaries. Once a unit is operational, Oriental parent companies grant many more degrees of freedom than US parent companies. When we deconstructed the results for Europe, comparing German and British MNEs as a group to Oriental MNEs, we found that the latter exercised greater overall control. With regard to output and bureaucratic control, we found that both US MNEs and those from the Middle East exercised greater control than Oriental MNEs. The study drew the aspect of international transfers into the picture and investigated the role of expatriates in controlling subsidiaries. It has been recognised that expatriates can form both direct and indirect means of control. In executing direct types of control, expatriates directly supervised decisions taken at subsidiaries. The study found that this role is particularly strong in MNEs from Asia-Pacific countries and German MNEs, and is much less important in subsidiaries of Anglo-Saxon MNEs. We found that subsidiaries of German MNEs experienced a very high level of control; indeed, the only control mechanism that German MNEs did not implement among subsidiaries was control by socialisation and networks. German and Japanese MNEs are perhaps more rooted in business systems concerned with the management of issues internationally than American or British companies. The second group reflected that Anglo-Saxon countries heavily used impersonal types of control mechanisms, specifically bureaucratic formalised control and output control. When we deconstructed the results for Europe, comparing German and British as a group to Oriental MNEs, reveals the latter as possessing greater overall control. With regard to output and bureaucratic control, we found that both US MNEs and those from the Middle East exercised greater control than Oriental MNEs. Headquarters can strategize to implement control by the informal and social means method by positioning a sizeable number of managers from the home country within the subsidiary. Indeed, our results revealed this as true. It seems that their presence has positive and significant effects on most levels of control: personal, output, bureaucratic and informal. Contrary to this, however, we found that the presence of a sizeable number of expatriates (as opposed to headquarters managers) leaded to greater autonomy in subsidiaries. In terms of strategy and structure, we indicated that the three distinct organisational models identified for MNEs could be recognised in our study. Control INFO was significantly, positively related to global strategy, multi-domestic and transnational strategy compared with PCC, BFC, and OUT control mechanism. Conversely, BFC had a significant, negative and weak relationship with global strategy and transnational strategy, and no relationship with multi-domestic strategy. In general however, we can deduce the existence of a tendency for global, transnational and multi-domestic MNEs to use indirect control mechanisms and informal control suited to their integrated organisational models to a larger extent. Our results confirmed previous studies in the field of organisation theory, in the sense that size is an important explanatory factor for differences in control mechanisms. In contrast to these studies, however, a dominant effect was found only for the indirect control mechanisms. Few detailed studies that have investigated the effect of size on the two indirect control mechanisms; in actuality, most previous studies have focused on the direct control mechanisms (personal centralised control and bureaucratic formalised control) only. As such, our study reconfirmed the importance of the variable size, but concluded that it is mainly associated with higher levels of indirect control. The age of the subsidiary does not seem to have a significant influence on the type of control mechanism that is exercised by headquarters towards a particular subsidiary. Our study investigated the importance of various MNE characteristics in an attempt to explain performance differences between MNEs. The advantage of this study is that many of the characteristics that have been identified in previous literature as being important factors influencing performance were included in our research design, in order for us to be able to answer the other research questions. This therefore allowed us to assess the relative importance levels of different variables in explaining performance differences between companies, such as: country of origin, industry, size, interdependence, local responsiveness, knowledge flows, and the strategy and structure of the MNEs.

This thesis answers calls for fine-grained studies of product diversification, in this case, predominantly using the resource based view of the firm. The context is UK providers of banking services. The thesis has developed the concept of resource matching. Resource matching combines levels of: resource heterogeneity, resource similarity and difference, and the external environmental setting of the organisation with the business performance of product diversification. Resource matching significantly increases the limited conceptual underpinning of diversification RBV by adapting and developing concepts from single firm RBV literature. Two new research strategies were developed to gather data on multiple resources and external factors. One was unused due to access issues during the credit crunch. The other, which was used, utilised multiple sources of publicly available information both qualitative and quantitative. These conceptual and methodological developments offer a way to restart the research on the impact of product diversification on business performance. This research has stalled due to conflicting results and methodological issues. Twenty nine providers of banking services in the UK where examined: building societies; other providers of retail banking services; providers of investment banking services; and combined banks which offer both investment and retail banking services. This thesis found: varying amounts of resource heterogeneity, resource bundles can be constructed from publicly available external data, performance in diversification does not adhere to the previously posited curvilinear pattern but to one of the greater the product diversification the greater the business performance risk and reward, with rewards being both positive and negative, and finally the external environment does vary within the industry. The results on product diversification performance suggest of a new way of looking at product diversification which might reconcile the previous conflicting results. A modified version of the conceptual model of resource matching was developed to take account of the results. Opportunities for further work include; studying other industries and providers of banking services in other countries, refining the single industry fine grained research methods and further developing the resource matching model.

Supply Chain Management (SCM) is becoming increasingly important in the modern business world. In order to effectively manage and integrate a supply chain (SC), a deep understanding of overall SC operation dynamics is needed. This involves understanding how the decisions, actions and interactions between SC members affect each other, and how these relate to SC performance and SC disruptions. Achieving such an understanding is not an easy task, given the complex and dynamic nature of supply chains. Existing simulation approaches do not provide an explanation of simulation results, while related work on SC disruption analysis studies SC disruptions separately from SC operation and performance. This thesis presents a logic-based approach for modelling, simulating and explaining SC operation that fills these gaps. SC members are modelled as logicbased intelligent agents consisting of a reasoning layer, represented through business rules, a process layer, represented through business processes and a communication layer, represented through communicative actions. The SC operation model is declaratively formalised, and a rule-based specification is provided for the execution semantics of the formal model, thus driving the simulation of SC operation. The choice of a logic-based approach enables the automated generation of explanations about simulated behaviours. SC disruptions are included in the SC operation model, and a causal model is defined, capturing relationships between different types of SC disruptions and low SC performance. This way, explanations can be generated on causal relationships between occurred SC disruptions and low SC performance. This approach was analytically and empirically evaluated with the participation of SCM and business experts. The results indicate the following: Firstly, the approach is useful, as it allows for higher efficiency, correctness and certainty about explanations of SC operation compared to the case of no automated explanation support. Secondly, it improves the understanding of the domain for non-SCM experts with respect to their correctness and efficiency; the correctness improvement is significantly higher compared to the case of no prior explanation system use, without loss of efficiency. Thirdly, the logic-based approach allows for maintainability and reusability with respect to the specification of SC operation input models, the developed simulation system and the developed explanation system.
