This PhD project aims to develop a cost modelling system to support lean product and process development. The system enables the designers to assess the design along with associated manufacturing processes and provides decision support at an early development stage. Design assessment at early development stage can help designers to take proactive decisions, eliminate mistakes and enhance product value. The developed cost modelling system to support lean product and process development incorporates three lean product and process development enablers, namely set-based concurrent engineering, knowledge-based engineering, and mistake-proofing (poka-yoke). To facilitate above explained lean enablers, the system architecture contains six modules, six separate groups of database, a CAD modelling system, and a user interface. The system modules are: (i) value identification; (ii) manufacturing process/machines selection; (iii) material selection; (iv) geometric features specification; (v) geometric features and manufacturability assessment; and (vi) manufacturing time and cost estimation. The group of database includes: (i) geometric features database, (ii) material database, (iii) machine database, (iv) geometric features assessment database, (v) manufacturability assessment database, and (vi) previous projects cost database. A number of activities have been accomplished to develop the cost modelling system. Firstly, an extensive literature review related to cost estimation, and lean product and process development was performed. Secondly, a field study in European industry and a case study analysis were carried out to identify current industrial practices and challenges. Thirdly, a cost modelling system to support lean product and process development was developed. Finally, validation of the system was carried out using real life industrial case studies. The system provides a number of benefits, as it enables designers to incorporate lean thinking in cost estimation. It takes into consideration downstream manufacturable process information at an early upstream stage of the design and as a result the designer performs the process concurrently and makes decisions quickly. Moreover, the system helps to avoid mistakes during product features design, material and manufacturing process selection, and process parameters generation; hence it guides toward a mistake-proof product development. The main feature of the system, in addition to manufacturing cost estimation, is set-based concurrent engineering support; because the system provides a number of design values for alternative design concepts to identify the feasible design region. The major contribution of the developed system is the identification and incorporation of three major lean product and process development enablers, namely set-based concurrent engineering, knowledge-based engineering and poka-yoke (mistake-proofing) in the cost modelling system. A quantification method has been proposed to eliminate the weaker solution among several alternatives; therefore only the feasible or strong solution is selected. In addition, a new cost estimation process to support lean product and process development has been developed which assists above explained three lean product and process development enablers.

Ao mesmo tempo, a evolução da Logística neste período permitiu a aproximação das organizações pertencentes a uma Cadeia de Suprimentos. Na busca pelo alcance e manutenção da competitividade, muitas organizações visualizaram esta aproximação como uma oportunidade de obter vantagens através da inclusão de fornecedores no processo de desenvolvimento de novos produtos e processos. Esta inclusão de fornecedores permite a criação de um ambiente de Desenvolvimento Simultâneo Tridimensional, no qual o produto, o processo e a cadeia de suprimentos são desenvolvidos ao mesmo tempo.

Concurrent engineering is an imperative concept in the world of product development. With the globalisation of industry, the market has been demanding higher quality products at lower costs, delivered at faster pace. With most companies today accepting the concurrent engineering approach as a formula for product development success, this approach is becoming ever more popular and dominating over the slower sequential product development method. Fast changes in technology, forced design cycle time reduction, emergence of new information technology and methodologies, as well as other aspects such as organisational and behavioural basis caused the sequential design process to progress into a concurrent engineering approach. The basic concept behind the concurrent engineering approach is that all parts of the design, manufacture, production, management, finance, and marketing of the product are usually involved in the early stages of a product’s design cycle, enabling faster product development through extensive use of simulation. Its key approach is to get the right data for the right person at the right time. There are forces that govern changes in the product development, and these forces must be steered towards prompt response to competition and higher productivity in order for companies to exist and successfully expand in the global market place. Concurrent engineering is made up of four key dimensions, one of them the communication infrastructure dimension, which is the focus of this study. This study defines the information infrastructure dimension, and some of the tools and technologies that support communication and collaboration. It then discusses how to employ the concurrent engineering approach from a communication infrastructure dimension point of view, starting with assessing the current product development process and eventually envisioning the path to take to a successful concurrent engineering environment. Communication infrastructure technologies and tools can be seen as central to a company’s implementation of concurrent engineering, as shown in the case studies covered in this work.

<p>The purpose of this thesis is to identify and analyze relevant dimensions of cooperation between design and production related to product development. The study also focuses on suggesting improvements of the co-operation dimensions between production departments and the product development departments in the Product Development Process (PDP) at Siemens Industrial Turbomachinery AB (SIT AB). SIT AB produces gas and steam turbines. Their increasing production pace and increasing number of product development projects have highlighted the importance of improved co-operations between departments within the company.</p><p>We have developed an analysis model including the dimensions of co-operation we found relevant for the study. These are Timing of Upstream – Downstream Activities; Richness & Quality of Information; Frequency of Information Transmission; Direction of Communication; Formalization of Communication; Organizational Support; Goal Optimization; Attitudes in Cross-functional Teams; and Understanding of Tasks.</p><p>For product development SIT AB follows an extensive process; the PDP. This is a sequential process where all activities are performed in sequence and therefore it obstructs the implementation of Concurrent Engineering. Concurrent Engineering aims to shorten development time and to consider the total job as a whole by performing independent activities in parallel. Hence, we argue that SIT AB should work toward a more integrated process with more parallel activities.</p><p>The performance in all the dimensions of co-operation differ between large and small projects since the co-operation in large projects work much better than in small projects due to better followed process description; more face-to-face discussions; a better balance between informal and formal communication; and more focus on project goals and team building.</p><p>The improvement proposals are presented in a separate chapter as actions classified according to the potential impact on the organization and the estimated difficulty to implement them. The proposals include for example: training more project managers; initiate work shop practice for design engineers; and give more and better explanations of decisions and actions.</p> / <p>Syftet med det här examensarbetet är att identifiera och analysera relevanta dimensioner av samarbete mellan produktion och konstruktion i samband med produktutveckling. Syftet är också att föreslå förbättringar i samarbetet mellan produktions- och konstruktionsavdelningarna i produktutvecklingsprocessen (PDP) på Siemens Industrial Turbomachinery AB (SIT AB). SIT AB producerar ång- och gasturbiner. Betydelsen av ett gott samarbete mellan avdelningar i organisationen har belysts i samband med att produktionstaken de senaste åren har ökat och fler produktutvecklingsprojekt har initierat.</p><p>Vi har utvecklat en analysmodell som innehåller de dimensioner av samarbete som vi anser är relevanta för området. Dessa är: timing av uppströms – nedströms aktiviteter, rikhet & kvalitet på information, frekvens av informationsöverföring, riktning på kommunikation, formalisering av kommunikation, organisatoriskt support, måloptimering, attityder i tvärfunktionella team samt förståelse för uppgifter.</p><p>Vid produktutveckling följer SIT AB den omfattande processen PDP. PDP är en sekventiell process där alla aktiviteter utförs i en sekvens vilket motverkar implementeringen av Concurrent Engineering. Concurrent Engineering syftar till att korta utvecklingstiden för produkter och beakta arbetet ur ett helhetsperspektiv bland annat genom utförande av oberoende aktiviteter parallellt. Därför anser vi att SIT AB ska arbeta mot en mer integrerad process med fler parallella aktiviteter.</p><p>Det är stor skillnad på prestationen i samarbetsdimensionerna mellan stora och små projekt. Stora projekt fungerar mycket bättre än små vilket kan relateras till att stora projekt följer processbeskrivningarna bättre, har en bättre balans mellan informell och formell kommunikation, och fokuserar mer på projektmål och sammansvetsade projektgrupper. Förbättringsförslagen är presenterade som konkreta åtgärder i ett separat kapitel och är klassificerade med hänsyn till varje förslags potentiella effekt på organisationen och dess uppskattade svårighetsgrad att implementera. Förslagen är bland annat att utbilda fler projektledare, inrätta verkstadspraktik för konstruktörer och ge fler och bättre förklaringar till beslut och handlingar.</p>

This thesis presents an extension of the contemporaryengineering design theory towards a unified view onsimultaneous development of products and manufacturing systems,i.e. concurrent engineering. The traditional engineering design theory explains therealization of a product design as a development of productstructure from four perspectives: technical process, function,technical solution, and physical embodiment. This thesisextends the engineering design theory with a set of definitionsand universal statements. These definitions and universalstatements describe manufacturing systems from same fourperspectives. In that context they also describe therelationship between a product and its manufacturing system.The thesis contributes to the creation of a single theoreticalsystem based on an integration of theories from two engineeringdesign schools, the WDK and the Axiomatic Design. WDKtheoriesare in this new context utilized for qualitative synthesis ofthe developed artifacts, while the Axiomatic Design is utilizedfor structuring and analyzing the corresponding quantitativeparameters. The definitions and universal statements describe thedevelopment structures for productsand manufacturing systems.This description is utilized for definition of a system fordevelopment of these structures, i.e. (i) a stage-gate-basedmanufacturing system development process, (ii) a developmentmethodology toolbox, and (iii) an information managementframework consisted of an information model harmonized with thesystems engineering data management standard STEP AP 233. The research has been carried out in a close collaborationwith Swedish manufacturing industry. The utilized researchmethodology is the hypothetic- deductive method, with casestudy as an observation method.
