    An innovative cost modelling system to support lean product and process development
    (Springer Science Business Media, 2013-03-31T00:00:00Z) Wasim, Ahmad; Shehab, Essam; Abdalla, Hassan S.; Al-Ashaab, Ahmed; Sulowski, Robert; Alam, Rahman
    This paper presents a cost modelling system for lean product and process development to support proactive decision making and mistake elimination at the design stage. The foundations of the system are based upon three lean product and process development enablers, namely: Set-based concurrent engineering, knowledge-based engineering, and mistake proofing (Poka-yoke). The development commenced with an industrial field study of eleven leading European industries from the aerospace, automotive, telecommunication, medical and domestic appliance sectors. Based on the requirements of industrial collaborators, the developed system comprises six modules: value identification, manufacturing process/machines selection, material selection, geometric features specification, geometric features and manufacturability assessment, and manufacturing time and cost estimation. The work involved the development of a feature-based cost estimation method for the resistance spot welding process. The developed system was finally validated using an industrial case study. The developed system has the capability to provide estimates related to product cost and associated values concurrently, facilitate decision making, eliminate mistakes during the design stage, and incorporate ‘customer voice’ during a critical decision making stage.

    Set-Based Concurrent Engineering process within the LeanPPD environment
    (2011-07-09T00:00:00Z) Khan, Muhammad; Al-Ashaab, Ahmed; Doultsinou, Athanasia; Shehab, Essam; Ewers, Paul; Sulowski, Robert; Frey, Daniel D.; Fukuda, Shuichi; Rock, Georg (Eds.)
    This paper presents a newly defined set-based concurrent engineering process, which the authors believe addresses some of the key challenges faced by engineering enterprises in the 21st century. The main principles of Set-Based Concurrent Engineering (SBCE) have been identified via an extensive literature review. Based on these principles the SBCE baseline model was developed. The baseline model defines the stages and activities which represent the product development process to be employed in the LeanPPD (lean product and process development) project. The LeanPPD project is addressing the needs of European manufacturing companies for a new model that extends beyond lean manufacturing, and incorporates lean thinking in the product design development process.
