    International audienceThe current globalization is faced to the rapid development of product design process with the different structure of the actor relationships in the process. Currently, the risk in the failure relationship among different actors in the project is shaped by the complexity towards the future all kinds of challenges. When it comes to the interdependent failure effect, the risk management for future organization structure in design process will be much more complex to grasp. In order to cope with adaption of Product-Process-Organization (P-P-O) model for industry of the future, we propose a risk management methodology to cope with this interdependent relationship structure. The main objective of this research is to manage the risks, so that the project manager can find the priority order of all the actors' total effect to the project with the consideration of interdependent failure affection, and according to the order, project manager can release corresponding respond measures

    Strategy realisation process: a modelling enabling approach

    Changing conditions within an organisation’s environment necessitate enactment of the strategy realisation process to produce relevant coping strategic intents to successfully reconfigure current, or potential, process networks to better exploit potential opportunities or minimise impacts of a potential threats. Literature regarding strategy realisation has not produced a coherent approach to describe and decompose the subprocesses of the strategy realisation, i.e., several different approaches have been taken to enact some components however there is no formal decomposition of such process. A revision of the strategy realisation literature was conducted and a formal decomposition model for the strategy realisation process was conceived. Various modelling tools, methods and techniques were surveyed to enable the underpinning of the proposed strategy realisation conceptualisation. Utilising a combination of static, causal and simulation modelling methods and tools, a research methodology was proposed to underpin aspects of the enterprise which would facilitate the decision making process of the strategy realisation process. Two case studies were identified in which the proposed methodology could be implemented. In the first case study, two differing strategic intents were analysed within the same organisation under opposing economic conditions. The second case study observed the implementation of a different system configuration to achieve a strategic intent. The strategy realisation process was studied using the described conceptualisation and the enterprise was modelled. Key variables, set by senior management were observed and quantitative analysis was undertaken and reported. It was concluded that the use of modelling methods providing quantitative and qualitative analysis facilitated the decision process within an organisation. A new conceptualisation of the strategy realisation process and the integration of modelling methods, tools and techniques were devised

    Error on title page - correct year of award is 2015 not 2013.Engineering design process (EDP) is a highly dynamic and creative process, and the capability in managing an EDP is considered as a major differentiating factor between competing enterprises. The most important prerequisite to establish an engineering design process excellence is a proper management of all the design process activities and the associated information. The most important impact in recent years on the EDP and on the activities of designers has come from computer-based data processing. Workflow, the automation of a business processes in whole or part, is a useful tool for modelling and managing a business process which can be reprensented by a workflow model (computerized process definition). By considering the dynamic characteristics of EDP, an EDP management system must be flexible enough to support the creative and dynamic EDP. After the introduction of engineering design process and its new trend, as well as flexible workflow technology, reviews of both engineering design process and its supporting flexible workflow technology shows that there is a need for a holistic framework to automate and coordinate design activities in the creative and dynamic EDP, and the flexible workflow technology should also be improved comprehensively in flexibility and intelligence in order to support better engineering design management. By introducing the relations between the EDP and flexible workflow, a virtual workflow and an autonomic flexible workflow built upon autonomic computing is investigated, and an innovative engineering design process management framework based on multi-autonomic objects flexible workflow is proposed. For the flexible workflow modelling in the framework, a dynamic instance-based flexible workflow modelling method is proposed for multi-autonomic objects flexible workflow. In order to improve the intelligence of flexible workflow, after examining the principle of flexible workflow intelligence in flexible workflow, a new flexible workflow autonomic object intelligence algorithm based on both extended Mamdani fuzzy reasoning and neural network is proposed, weighted fuzzy reasoning algorithm, as well as precise and fuzzy hybrid knowledge reasoning algorithm is designed; a bionic flexible workflow adaptation algorithm is proposed to improve the intelligence of autonomic object flexible workflow further. According to the characteristic of EDP, such as cross-enterprises and geographical distribution, and in order to realize the flexible execution of distributed flexible workflow engine, a distributed flexible workflow engine architecture based on web service is proposed and a flexible workflow model description method based on extended WSDL (Web Service Description Language) and BPEL4WS (Business Process Execution Language for Web Services) is proposed. A flexible workflow prototype system supporting engineering design process is implemented according to the proposed EDP management framework in Microsoft VS.Net 2005 environment. The framework is demonstrated by the application in an EDP of a MTO company, and it shows that the proposed framework can support the creative and dynamic process in an efficient way. Finally, the strengths and weakness of the framework as well as the prototype system is discussed based on the results of the evaluation, and the proposed areas of future work are given.Engineering design process (EDP) is a highly dynamic and creative process, and the capability in managing an EDP is considered as a major differentiating factor between competing enterprises.

    Feedback systems in the design and development process

    Feedback is essential in the design and development process, occurring in the generation of new designs, in the adaptation of development projects to emerging information, and in coordination and collaboration of project participants—among many other aspects. Feedback also contributes to development project complexity and may cause resistance to desirable changes. But despite the importance of feedback in the design and development process (DDP), relatively few publications have examined this topic in an integrated way. This article makes two contributions towards addressing the gap. First, a conceptual framework is developed to organise perspectives on feedback in the DDP literature. The framework shows how feedback occurs at different levels of the design and development process and how it affects important DDP behaviours, namely goal-seeking, learning and emergence. Second, a system-theoretic model of feedback situations in the design and development process is introduced to synthesise key ideas. We provide concrete examples to show how this new model can be used to frame DDP situations and draw out feedback-related insight
