    Manufacturing Industry is moving towards adoption of 3D models as the ultimate authoritative source for complete product definition replacing 2D drawings, which is called “Model-Based Definition”. Starting its journey from geometric information on design, manufacturing, and inspection, the targets are to achieve the ultimate goal of lifecycle model based enterprise, requiring MBD to be more comprehensive and challenging structure of information instead of just a geometric model. The industry has not yet fully achieved implementation of MBD to whole product lifecycle. This journey is long and tough, and we are still at an early stage, but it will be a decisive factor in gaining competitive advantage by the early adopters, especially in high-value manufacturing. Complete adoption of MBD has several issues and challenges that need to be addressed. This paper presents a review of current literature, intending to cover present state of knowledge, issues, challenges, and future research directions, in the development and adoption of MBD

    Get PDF
    Purpose The main purpose of this paper is to present lean implementation in hospital supply chain management (HSCM) and propose a new conceptual framework tailored specifically to the needs of Saudi health-care organizations. Design/methodology/approach This paper starts with an in-depth review of existing frameworks or models for lean implementation in health care in general and in HSCM specifically. Based on the literature studies and taking experts’ opinions into account, a new framework for lean implementation in the Saudi HSCM is presented. Findings A new lean implementation framework is offered to decision-makers in the health-care organization for implementing a lean approach in HSCM practices. Research limitations/implications This study focused on health-care organizations, which were selected from hospitals operated by the Ministry of Health and only those hospitals that are accredited by both the Saudi Central Board for Accreditation of Healthcare Institutions and the Joint Commission International. The framework is limited to Saudi health care. Practical implications The lean supply chain management (LSCM) framework is easy to understand and use without much complexity. This simplicity makes the LSCM applicable in health-care settings. Further, LSCM was validated in three different hospitals, and it helped them to identify and improve their non-added activities, thereby readying them for lean deployment in HSCM. Originality/value Little attention has been paid to implementing a lean approach by health-care providers in developing countries. This study presents a new framework that is considered the first of its kind for implementing lean in HSCM in Saudi. This framework could help HSCMs’ decision-makers to implement lean successfully in HSCM practices

    Interventions to develop an improvement culture within nonprofit organization: The case of Saudi Arabia

    It has been confirmed that organizational culture has a remarkable impact on facilitating continuous improvement. Nonetheless, little empirical research has investigated how organizational culture can facilitate continuous improvement. Therefore, this paper asks what interventions facilitate a continuous improvement culture within nonprofit organizations. Qualitative data are suggested as an appropriate method for answering the research question. The present research adopted an interpretive paradigm whereby reality, treated as a subjective and multiple entity that is “socially constructed”, can be mentally explored from the participants' perspectives. Grounded theory was the chosen approach for collecting and analysing the qualitative data; thus, the constructed theories were ‘grounded’ in the data themselves. Thirty one interviews in fifteen nonprofit organizations yielded data which, when analysed revealed a number of interventions, developed by the participants during five focus group discussions

    Assessing the leanness of a supply chain using multi-grade fuzzy logic: a health-care case study

    Get PDF
    Purpose Numerous and diverse organizations have implemented lean principles and practices, which concentrate on improving the efficiency of business processes by reducing cost, waste, consumptions and effort. However, previous assessments have not focused on the leanness of the supply chain in a health-care setting. This paper aims to introduce a method for assessing the successful implementation of lean principles and tools in a supply chain. Furthermore, this paper validates the method in a health-care organization. Design/methodology/approach This paper starts with an extensive literature review on assessing leanness and using multi-grade fuzzy logic. Then, a conceptual model was developed to measure leanness. The conceptual model was validated by discussing the initial version with select academic experts, especially those who deal with leanness in health-care organizations. After responding to the experts’ valuable comments, the health-care organization that is the focus of this case study was chosen based on two criteria. The first criterion was the organization’s ability to participate in the study, and the second was the organization’s commitment to implementing lean principles. These criteria were important to ensure the organization had the necessary foundation for implementing change initiatives such as lean process improvements. Next, a multi-grade (multi-attributes) fuzzy logic was used for leanness measurement. A leanness index was calculated, and the results were validated using experts from the case study organization. Finally, the weaker areas of the organization’s processes were identified to point the way for further improvements. Findings The assessment indicated that the case study organization is not lean. The organization’s weaker attributes were identified, and improvements have been suggested. Research limitations/implications This study focused on a single health-care organization, which was selected from a limited pool of potential organizations, namely, organizations which are accredited by both the Saudi Central Board for Accreditation of Healthcare Institutions and the Joint Commission International. The scope of future research should be extended to multi-case studies to enhance the findings presented in this paper. This paper’s findings can be used to help decision-makers at health-care providers to implement lean thinking in supply chain processes. Practical implications This research may be interest to practicing supply chain managers, as it proposes what enablers, factors and attributes should be emphasized in lean implementation. The proposed model can work as an assessment tool to identify the gap between the present level of leanness and the desired leanness state so the health-care organization can identify what can be improved. This model enables decision-makers in hospital supply chain to take suitable actions for improving lean implementation level. Originality/value This study makes an original contribution to the body of research concerning lean principles; the study developed a conceptual model for leanness assessment that can be applied to the supply chain of health-care organizations. Indeed, the conceptual model is likely to be useful for assessing leanness outside of the health-care field, which suggests avenues for future research

    Organised by: Cranfield UniversityThis paper presents the general model of the Product Development Process (PDP) in the Metal mechanics Industry in Barranquilla-Colombia, since this sector contributes significantly to the productivity of this industrial city. This case study counted on a five-company sample. The main goal was to model the current conditions of the PDP according to the Concurrent Engineering philosophy. The companies were selected according to their productive profile, in order to contrast differences regarding the structure of their productive processes, conformation of multidisciplinary teams, integration of different areas, customers and suppliers to the PDP; human resources, information, technology and marketing constraints.Mori Seiki – The Machine Tool Compan

    Trends in model-based definition based assembly information in high-value manufacturing

    Get PDF
    3D modelling is in use for the last many decades at various stages of the product lifecycle i.e., design, analysis, manufacturing, and inspection. In the modern era of Industry 4.0 where the high-value manufacturing industry is aiming at the digital thread, Model-Based Definition (MBD) has been considered as the heart of this transformation. However, MBD needs to be realized throughout the product lifecycle to get full advantage. In literature, considerable work has been found focusing on a shift from traditional 2D drawings to MBD. The majority of this work concentrates on design, manufacturing, and inspection stages, whereas, there is a lack of work in the area of MBD based assembly information. This paper focuses on the current state of knowledge in MBD based assembly information, trends, challenges, and future research directions
