Product information management in concurrent design systemsTan, Ah Kat, n/a January 2003 (has links)
In this thesis, the management of product information in concurrent design
systems has been investigated with particular reference to product
development in small and medium enterprise (SME) industry and design
education at polytechnic level in Singapore. From a critical review of the
relevant literature on product design and development processes,
concurrent engineering, concurrent design systems, product data
management and related methods, it is found that there is a clear need for a
new design of a system for organizing and managing product information
in a concurrent design environment in the above contexts. This finding has
led to the development of a conceptual rationale, termed the Design Tensor
Method, and the design and development of an innovative product
information management system called PRIMAS. PRIMAS is a systematic
methodology for the classification, organization, integration,
communication, storage and management of product information in the
product development process. A software prototype based on PRIMAS has
been subsequently developed. PRIMAS along with its conceptual principles
have been applied and tested in a product design project in a tertiary
educational institution and in two significant industrial product
development projects based respectively in two SMEs. Positive evaluation
feedback on PRIMAS has been obtained in these studies. The product
development projects investigated with PRIMAS have also produced
outcomes that meet the original specified design requirements. The
findings from this research have led to the conclusion that PRIMAS is a
viable product information management system that can be used effectively
for managing product information in concurrent design projects in SME
industry and design education. Substantial PRIMAS databases of useful
product information have been compiled for the product development
projects investigated with PRIMAS. Finally, recommendations are made for
future research.

Processer och metoder som möjliggör för en effektiv produktframtagningFriberg, Caroline, Björkell, Mattias January 2010 (has links)
<p>The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they’re facing and offers a great potential to create significant competitive advantages.

Cooperative Modeling and Design History Tracking Using Design Tracking MatrixKim, Jonghyun 2009 August 1900 (has links)
This thesis suggests a new framework for cooperative modeling which supports
concurrency design protocol with a design history tracking function. The proposed
framework allows designers to work together while eliminating design conflicts and
redundancies, and preventing infeasible designs. This framework provides methods to
track optimal design path and redundant design history in the overall design process.
This cooperative modeling architecture consists of a modeling server and voxel-based
multi-client design tool. Design change among server and multiple clients are executed
using the proposed concurrency design protocol. The design steps are tracked and
analyzed using Design Tracking Graph and Design Tracking Matrix (DTM), which
provide a design data exchange algorithm allowing seamless integration of design
modifications between participating designers. This framework can be used for effective
cooperative modeling, and helps identify and eliminate conflicts and minimize delay.
The proposed algorithm supports effective cooperative design functions. First, it
provides a method to obtain the optimal design path which can be stored in a design
library and utilized in the future design. Second, it helps capture modeling pattern which can be used for analyzing designer's performance. Finally, obtained redundancies can be
used to evaluate designer?s design efficiency.

A case study of accelerated product developmentNchapha, Christina Mahlompho Nokujabula 27 August 2012 (has links)
M.Phil. / Product development is very important to the survival of an engineering organisation. It therefore needs to be carefully managed and completed within planned time and allocated resources. The main focus in this dissertation is therefore investigating how time could be reduced in the product development process. • Customers are not always patient enough to wait for the "best" products that are still being developed; they want products immediately and would therefore choose the "next best" products available. Some customers are willing to pay high prices to get exactly what they need as soon as possible. This study looks at how to accelerate the product development process without sacrificing quality and product performance. The study also investigates the case of development of a Boeing 777 commercial aircraft and contrasts the Boeing product development process against the product development theory. Boeing 777 is a globally well known commercial aircraft that was designed in the record time. Investigating the Boeing 777 product development process will provide good indicators of approaches that are currently most applicable in the real world.

Re-engineering the project procurement process through concurrent engineeringBowron, John January 2002 (has links)
The construction industry in the United Kingdom is a multi-billion pound business that contributes, on average 10% of the UK Gross Domestic Product (GDP). However, it is seen by many to be underachieving in terms of service delivery and investment opportunities. Projects are frequently late and over budget much to the disappointment of those involved in the industry and especially clients. Many investigations have been commissioned and resulting reports have suggested improvements in the way the industry is organised. Procurement of construction projects in the main are undertaken using methods that support fragmentation and adversarial relationships. However, with the introduction of partnering and prime contracting some improvements have been made. Procurement of a construction project begins with the strategies developed during briefing and is only complete when the facility is handed over to the client, some contract strategies allow for the facility to be completed once it is in operation, has been maintained and eventually is demolished. Costings and programmes are then related to life-cycle issues and aspects such as maintenance have to be taken into account during the facility development stages. The adoption of Concurrent Engineering (CE) is seen to offer the construction industry a way forward. Having been adopted extensively by manufacturing in its product development stages a similar adoption by the construction industry would go some way to achieving the 30% improvement in real terms suggested by Latham [1994] and Egan [1998]. The research described in the thesis aims to develop a new procurement method for the delivery of construction projects. The approach adopted was to identify current methods of procurement and the problems associated with each method. Then using Concurrent Engineering as a basis, a new procurement model was developed that offered potential improvements in the construction process between the stages of Clients Briefing and Detailed Design. The resulting model was evaluated through the application of CE principles into the process and by the presentation and discussion of the method with a number of industry participants, followed by the completion and assessment of a questionnaire. The model was shown to fulfil the principles of CE and could be adopted into construction. It offers a new approach to procurement which in turn would save costs and time and potentially improve the quality of the final construction product.

Studie och förbättring av Saab Training & Simulations projektmodell och arbetssätt / A study and improvment of Saab Training & Simulations project model and working methodsEriksson, Gusten, Persson, Karin January 2017 (has links)
The purpose of this bachelor thesis was to examine risks in Saab Training & Simulations project model and the way they execute projects to present an improvement proposal. The study was executed through quantitative and qualitative data gathering in form of interviews and collecting of project reports. The result showed differences between the project model and the execution. The risks were mainly connected to the execution and could be summarized in to three problem areas, manager dependent project management that creates confusion and uncertainty in the line organization and project groups, communication faults during the execution resulting in unnecessary purchases and that the projects show a tendency of needing more resources at the end of the project due to postponed milestones. Based on the findings an extensive literature review treating general project management, project model and methods as concurrent engineering and agile methods were made. After further analysis, an improvement proposal could be formed, however since Saabs project model were found adequate with several parallel and time effective element the improvements are focused towards the way of working in four hands-on suggestions. • Clear assignation of responsibility - A clearer assignation of responsibility reduces the risks associated with ambiguity and misunderstandings, as a result of person dependent project management. • Project pulse - Adoption of pulse meetings in the project groups. • Increase customer contact - By increasing the contact and integration with the customer could it be assured that their demands are meet even though it is not known during the sale. • Design for manufacturing and assembly - Clearer guidelines and a way of working and cooperating internally during the product realization could decrease the risk of unnecessary purchases. / Syftet med examensarbetet var att undersöka Saab Training and Simulations projektmodell och arbetssätt för att sedan formulera ett förbättringsförslag. Studien genomfördes genom en kvantitativ och en kvalitativ datainsamling i form av intervjuer och insamling av projektrapporter. Resultatet av datainsamlingen visade att det fanns skillnader mellan den projektmodellen och det arbetssättet som tillämpades på företaget. Riskerna som fanns i utförandet var relaterade främst till arbetssättet och inte projektmodellen. Riskerna kan sammanfattas i tre problemområden. De problemområdena är individberoende projektledning som orsakar missförstånd och osäkerhet i linjeorganisationen och projektgrupperna, kommunikationsbrister under projektgenomförandet som kan resultera i onödiga inköp samt att projekten tenderar att behöva sätta in extra resurser i slutet av projekten som en följd av uppskjutning av milstenar. Vidare genomfördes en litteratursökning som behandlade generell projektledning och olika relevanta projektledningsmodeller eller metoder såsom agila metoder och concurrent engineering, baserat på de risker som upptäcktes under datainsamlingen. Utifrån detta formulerades ett förbättringsförslag. Eftersom projektmodellen innefattar flera parallella inslag anses den vara duglig och det kommer därför inte att presenteras ett förbättringsförslag för modellen. Däremot presenteras ett förbättringsförslag som berör arbetssättet som består av fyra åtgärder. • Tydligare fördelning av ansvar i projekten - En tydligare ansvarsfördelning i projekten minskar riskerna för otydligheter och missförstånd vid individberoende projektledning. • Projektpuls - Projektpuls är ett tillvägagångssätt att öka kommunikationen i projektgruppen under projektgenomförandet • Ökad kundkontakt - Genom en ökad kundkontakt under projektgenomförandet kan kundens önskningar tillgodoses lättare även i de fall där försäljningsunderlaget från marknad är bristfälligt. • Design for manufacturing and assembly - Tydligare riktlinjer och ett arbetssätt för det interna samarbetet under produktframtagningen minskar riskerna för exempelvis onödigt inköp.
