Prolonging the service life of TsVN-8 main circulation pumps for RBMK reactors
Thermal Engineering, 1997Co-Authors: A. S. Agalakov, V. B. Zinov'ev, Vitaly Ivanovich Kostin, E. G. Novinskii, V. M. PopovAbstract:The Design of the main circulation pump for a nuclear power station with an RBMK reactor is discussed. The concept of the main circulation pump that was adopted at the Design Office and the development work for modernizing several units of the pump, which made use of operating experience, enabled us to improve the safety of the pump and prolong its service life.

Strategic approaches to engineering Design process modelling
Business Process Management Journal, 1998Co-Authors: David T. WrightAbstract:The effective and efficient management of information across an enterprise, and detailed understanding of the business environment is critical to long‐term sustainable success. It is necessary to focus enterprise activities on meeting order qualifying and order winning criteria (OQC, OWC). Where customer information is embedded in a function‐centered business process, such as engineering Design Office “response‐to‐tender”, a greater understanding can yield insight and lead to business benefits. This paper reports the use of two approaches to modelling this business process: a commercially available modelling tool, ICL ProcessWise Workbench; and object‐oriented qualitative analysis (OOQA) and artificial neural network process modelling (ANNPM) developed by the authors. The ICL software proved excellent at initial process mapping, but required high skill levels for the detailed modelling. The use of OOQA captures significant information, and supports development of object‐oriented (OO) management information systems. The ANNPM proved capable of being used to predict engineering Design Office “response‐to‐tender” duration, resource, and costs.

Enhanced strength analysis method for composite open-hole plates ensuring Design Office requirements
Composites Part B: Engineering, 2014Co-Authors: Frédéric Laurin, Nicolas Carrère, Jean-françois Maire, Stéphane MahdiAbstract:The use of unidirectional carbon fibre-reinforced composites in the Design of primary structures, such as the centre wing box, has spread increasingly over the past few years. However, composite structures can be weakened by the introduction of geometrical singularities, such as holes or notches. The semi-empirical aspect of the current open-hole failure approaches requires the allowables to be systematically fitted against specific test results. This point constitutes a strong limitation for optimum Design. A simplified strength analysis method for perforated plates is presented, ensuring Design Office requirements in terms of precision and computational time. The predictions of the proposed approach are compared successfully with a large experimental database, with different configurations of perforations, different stacking sequences and in different Carbon/Epoxy materials.

Sensitivity analysis and optimum Design curves for the minimum cost Design of singly and doubly reinforced concrete beams
Structural and Multidisciplinary Optimization, 2000Co-Authors: Boris Ceranic, Colin FryerAbstract:This paper reports on the application of the Lagrangian Multiplier Method (LMM) to the minimum cost Design of both singly and doubly reinforced concrete rectangular beams under limit state Design conditions. Cost objective functions and stress constraints are derived and implemented within the optimization method. Cost sensitivity analysis, detailed testing and comparisons with conventional Design Office methods are performed and the results reported, showing that the Lagrangian multiplier method can be successfully applied to the minimum cost Design of reinforced concrete beams. The proposed approach is effective and reliable without the need for iterative trials. Optimum Design curves have been developed that can be used without prior knowledge of optimization. Despite the simplification of the cost model and the assumptions made, satisfactory and reliable results have been obtained and confirmed by using standard Design Office procedures.

Summer Design Office - an opportunity and a challenge for students and small enterprises
2007Co-Authors: J. Rismoen, I. SundbyAbstract:The summer Design Office project was arranged for the first time in Norway in 2006. The project included two Design Offices consisting of four and five master students of Design engineering who served a total of 15 smaller local businesses. The goal of the project was to give students practical experience, and to provide smaller enterprises with an opportunity to utilize Design competence for a relatively low cost. The students lived nearby their customers during the seven week duration of the project. The assignments ranged from standard product Design development to graphic Design and city planning. At the end of the summer, the feedback from both students and enterprises was very positive. The students reported increased skills in customer interaction and business management. As a result of both local and national attention, the project organizers were approached early by interested companies for next year's project.
