    Molina-Cristobal, Arturo; Chen, Xin; Guenov, Marin D.; Riaz, Atif; van Heerden, Albert S. J. (AIAA, 2019-11-20)
    A common probabilistic approach to perform uncertainty allocation is to assign acceptable variability in the sources of uncertainty, such that prespecified probabilities of meeting performance constraints are satisfied. ...
  • Intermodal integration of large volume air cargo 
    Guenov, Marin D. (2006-09-01)
    Proposed is a novel air freight concept for intermodal container transport. The aim is to utilise the standardised (ISO) 20 and 40 foot containers currently in operation. Instead of a completely new, purpose built aircraft ...
  • A knowledge based expert system for moulded part design 
    Guenov, Marin D.; Lockett, Helen L. (Design Society, 2007)
    In today's competitive market many consumer products are designed with complex curved shapes to meet customers' demands for styling and ergonomics. These styled products are commonly manufactured using moulding processes ...
  • A knowledge based manufacturing advisor for CAD 
    Lockett, Helen L. (Cranfield UniversitySchool of Engineering, 2005-07)
    This thesis presents a knowledge based manufacturing advisor for Computer Aided Design. The aim of the project has been to develop techniques that can help designers to evaluate the manufacturability of moulded parts ...
  • A knowledge management methodology for aproduct development environment 
    Levett, G. P. (Cranfield University, 2001-06)
    The subject of this Engineering Doctorate research is Knowledge Management (KM) which is a philosophy for improving core business activities of a organisation based upon the examination and development of its knowledge-base. ...
  • Knowledge-based cost modelling for innovative design 
    Rehman, S. (Cranfield University, 2000)
    The contribution to new knowledge from this research is a novel method for modelling production costs throughout the design phase of a product's lifecycle, from conceptual to detail design. The provision of cost data ...
  • Local pareto analyser for preliminary design. 
    Utyuzhnikov, S. V.; Maginot, J.; Guenov, Marin D. (2006-09-01)
    In the design process of complex systems, the designer has to solve an optimisation problem, which involves coupled disciplines and where all design criteria have to be optimised (traded-off) simultaneously. This problem ...
  • Managing assumption-driven design change via margin allocation and trade-offs 
    El Fassi, Soufiane; Chen, Xin; Riaz, Atif; Guenov, Marin D.; van Heerden, Albert S. J.; Jimeno Altelarrea, Sergio (Taylor and Francis, 2023-10-11)
    Assumptions are commonly introduced to fill gaps in knowledge during the engineering design process. However, the uncertainty inherent in these assumptions constitutes a risk that ought to be mitigated. That is, assumptions ...
  • Margin allocation and trade-off in complex systems design and optimization 
    Guenov, Marin D.; Chen, Xin; Molina-Cristobal, Arturo; Riaz, Atif; van Heerden, Albert S. J. (AIAA, 2018-05-01)
    Presented is an approach for interactive margin management. Existing methods enable a fixed set of allowable margin combinations to be identified, but these have limitations with regard to supporting interactive exploration ...
  • A method for generating a well-distributed Pareto set in nonlinear multiobjective optimization 
    Utyuzhnikov, S. V.; Fantini, Paolo; Guenov, Marin D. (Elsevier Science B.V., Amsterdam., 2009-01-15)
