DECODE - Decision Environment for Complex Design


Item added January 2012

www.soton.ac.uk (This is EPSRC funded)

Abstract: The research to be undertaken under DECODE will investigate design decision making tools that provide holistic optimisation at a system level to maximise satisfaction of all the stakeholders associated with the system. Uniquely DECODE will provide active design exploration of systems level trade-offs between performance, unit cost and system life-cycle costs based on a 'design mission control capability'. To do this an innovative design decision support environment that focuses on Value metrics is being built. This will allow a Value-Driven 'mission control capability' for design decision making to be researched. It will integrate early concept design exploration with full resolution, geometry backed design computations and detailed manufacturing and operations models.

An Aerospace Component Cost Modelling Study for Value Driven Design


Item added January 2012

http://eprints.soton.ac.uk/64914/1/Cheu_09.pdf

Abstract: Demand is increasing in aero-engine products for better efficiency and environmental performance whilst keeping the cost low. Unlike performance, the physics behind cost is least understood. This paper presents a proposed unit cost modelling methodology applied to a Rolls-Royce aero-engine fan blade. An objective of the cost model is the allow engineers to understand the breakdown of cost. A value driven design concept is outlined and presents an opportunity to conduct design optimisation. Keywords: Cost Engineering, Cost Modelling, Unit Cost, Value.

 

Predicting Manufacturing Cost by generating a Factory Simulation from CAD Geometry


 

Item added January 2012

http://eprints.soton.ac.uk/183937/1/S_Jinks_Materials_Conference_Abstract.pdf

Abstract: Analysis of a design is required to determine if the design meets specification. The cost analysis process requires information from multiple sources including results from other analysis. A framework is presented that combines component CAD geometry, dynamic factory simulation, manufacturing and cost knowledge, to reduce the time and improve the accuracy of cost analysis.

Utilising dynamic factory simulation to improve unit cost estimation and aid design decisions


Item added January 2012 (Restricted)

Link to poster

Utilising dynamic simulation methods to estimate manufacturing resources, can improve unit cost estimation and aid design decisions. This paper introduces a framework specification that combines Computer Aided Design (CAD), Computer Aided Process Planning (CAPP) and Discrete Event Simulation (DES) technologies. The framework is used to aid a design team in understanding the consequences of design decisions in terms of cost and manufacturing resources, by returning unit cost and manufacturing based results, directly to the design team, within the design environment. Dynamic Resource Estimation System (DRES) is a system being developed to implement the framework and is presented in this paper.

Abstract: The aim of this research is to develop a framework for cost uncertainty management and modelling at the bidding stage of Contracting for Availability (CfA) in the defence industry. The thesis presents the existing literature associated to uncertainty in cost estimation, whilst the current practice is demonstrated based on interaction with seven organisations involved in the defence industry. A software prototype, Uncertainty Tool for Assessment and Simulation of Cost (U-TASC), has been developed to implement an integrated cost uncertainty management and modelling framework.

Abstract: This paper provides a cost estimating framework for electrical, electronic and electromechanical (EEE) components obsolescence, which represents the main source of obsolescence issues, owing to the increasingly short life cycle of these types of component. The framework comprises several areas: component complexity levels, obsolescence management levels, obsolescence resolution profiles and obsolescence cost metrics. The framework is able to estimate the non-recurring cost of obsolescence during the contracted period within the in-service phase. This is based on the information available at the bidding stage concerning the product breakdown structure (PBS) and the obsolescence management strategy deployed. This framework has been validated at four different UK organizations in the defence and aerospace sectors using seven case studies, one of which is presented in this paper in detail.

Abstract: The Industrial Product-Service System (IPS2) takes a whole life cycle view in order to consider the total cost of the IPS2 offering. This paper focuses on the concept of customer affordability which aims to review current practice in industry and with interaction between customer and solution providers to identify factors affecting affordability. It secures a standard definition and proposes a measurement technique called the Affordability Index (AI) within the aerospace defence industry. An Affordability Capability Audit Tool is developed to give an indication of the confidence level about the AI. It identifies challenges in industry and outlines opportunities for further research scope.

Sponsor: EU-FP7

Abstract: Cost estimating for long-term digital preservation has received attention of many manufacturing companies and firms who are interested in performing preservation for their data. Cost modelling techniques are being used to find an estimate to the costs incorporated in digital preservation and their economic impact on firms. Cost model will lead industries to better understanding of the economic impact of digital preservation. Understanding the challenges facing the development of a cost model, from accuracy, sources of error and lack of information, will provide a better risk mitigation and therefore a more efficient model.

Cost Modelling System for Lean Product and Process Development


Item added January 2012

Abstract:This paper presents a cost modelling system for lean product and process development, to support proactive decision making during early design stage. The foundations of the system are based upon three lean product development enablers namely: Set-Based Concurrent Engineering, Knowledge-based Engineering, and mistake proofing (Poka-yoke). However, the intent of this paper is to demonstrate one of the enablers (Set-Based Concurrent Engineering). The development of the system was the result of conducting an industrial field study; participants included eleven leading European industries from the aerospace, automotive, telecommunication, medical and domestic appliance sector. Based on the requirements of industrial collaborators, the system was developed which consisted of 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 system was validated using a case study.

Key words: Lean product and process development, Cost Modelling, Set-Based Concurrent Engineering.

A Design to Cost System for Innovative Product Development


item added January 2012

Abstract: This research paper presents a prototype object-oriented and rule-based system for product cost modelling and design for automation at an early design stage. The developed system comprises a computer aided design (CAD) solid modelling system, a material selection module, a knowledge-based system (KBS), a process optimization module, a design for assembly module, a cost estimation module and a user interface. The system development process has passed through four major steps: constructing the knowledge-based and process optimization system; developing a design for assembly module; integrating the KBS with both a material selection database and the CAD system; developing and implementing a fuzzy logic approach to generate reliable estimation of cost and to handle the uncertainty in the cost estimation model that cannot be addressed by traditional analytical methods.

Improvement of Cost Estimating Internal Practice


Item added January 2012

Client, Ford

Sponsor: EPSRC

Abstract: This thesis is concerned with understanding the internal costing practices employed by commercial and engineering disciplines of cost estimating for generating estimates at the conceptual design stage of complex hardware products. It examines whether there is a formal structure in the interaction between the two groups that can be represented within a model. The aim is to develop a framework that will formalise and improve the communication of commercial and engineering disciplines in cost estimating.
