Application of an engineering and management approach to the incorporation of an information management system at a manufacturing company

Thesis (S.M.)--Massachusetts Institute of Technology, System Design & Management Program, February 2000.Includes bibliographical references (leaf 56).Sikorsky Aircraft Corporation, a helicopter manufacturing company, is in the process of implementing a new enterprise product data management (PDM) system. This PDM system is a commercial product that will affect Sikorsky in both the system design and management behaviors of the company's current business processes. As PDM systems do not simply unwrap themselves within a company, potential implementation issues will be examined and evaluated. Principles, processes, and tools for system design and management of large, complex systems learned in the SDM program will be used to assist in this effort. This thesis will examine the system architecture and engineering of key interfaces between the PDM system and other mission critical systems and processes at Sikorsky.by Jeffrey P. Ezzo.S.M

An Approach to Conceptual and Embodiment Design within a New Product Development Lifecycle Framework

[EN] The design of new innovative products is the result of an accurate and precise management of knowledge sources all over its life cycle, such as technology, market, competitors and suppliers. The work contributes with a framework that shows how the knowledge sources influence in the state-of-the-art and market needs so that they become opportunities for innovating products addressing the whole product life cycle. It provides a systematic path from the early generation of ideas to the production of a new product proposal. Through a deep analysis of previous research works of new product innovation life cycle development frameworks and linking it with knowledge management, strategic planning and scorecards, we came out with a structured contribution. The result considers the concurrent activities and its relationships all the way through the product life cycle that can help in creativity and innovation, combined with a process management proposal. Managing the sources of knowledge in highly dynamic markets and technologies is one of the major difficulties involved in innovative products design and development. The emerging knowledge from external sources is confronted with organisation internal knowledge and experience in order to achieve the first product correct.This work was supported by the Spanish Government and the Universitat Jaume I of Castellon (Spain) through research [project number P11B2009-37], entitled 'Methodologies for Implementing Product lifecycle management tools for mechanical Small and Medium Enterprises'.Vila, C.; Albinana, JC.

Guidelines for the successful implementation of concurrent engineering practices in the South African electronics industry

Bibliography: leaves 122-126.This thesis describes the concurrent engineering environment necessary for developing electronics products in the 1990s, and beyond. The broad scope of the research has made it possible to derive guidelines for the successful implementation of concurrent engineering in the South African electronics manufacturing industry. For a long time, design and manufacturing have been viewed as two distinct steps that must be sequential. The problem is that this process delays product introductions and promotes design errors that have to be caught either in the field or on the factory floor. Nevertheless, these drawbacks were viewed as simply an evil of modern industry. Today, progressive companies see that there is a better way to do things. Viewing product design and manufacturing engineering as separate entities is yesterday's technology. Both can be done at the same time in the process called Concurrent Engineering (CE)

Tailoring concurrent engineering to small companies

This thesis presents the findings of a four year collaborative programme betvveen Middlesex University and Rimmer Brothers, a small medical device manufacturer. During this time the author and other associates have introduced to the company a new approach to product design based on the principles of Concurrent Engineering (CE). A review of CE case studies reveals how its usage is mainly confmed to large organisations, despite offering universally applicable advantages. In applying such ideas to a company of only ~50 employees, it has become clear that a number of 'environmental factors' including culture, product complexity and available resources influences the implementation and success of CE schemes. Most notably, resource shortages diminish the effects of lead time compression. Use of a modified implementation for the development of several new products has yieldedcost reductions approaching 50% - results comparable with large companies. This demonstrates that if due consideration is given to these factors, then CE can be seen to be a powerful and effective tool in any size of organisation

Analysis of manufacturing operations using knowledge- Enriched aggregate process planning

Knowledge-Enriched Aggregate Process Planning is concerned with the problem of supporting agile design and manufacture by making process planning feedback integral to the design function. A novel Digital Enterprise Technology framework (Maropoulos 2003) provides the technical context and is the basis for the integration of the methods with existing technologies for enterprise-wide product development. The work is based upon the assertion that, to assure success when developing new products, the technical and qualitative evaluation of process plans must be carried out as early as possible. An intelligent exploration methodology is presented for the technical evaluation of the many alternative manufacturing options which are feasible during the conceptual and embodiment design phases. 'Data resistant' aggregate product, process and resource models are the foundation of these planning methods. From the low-level attributes of these models, aggregate methods to generate suitable alternative process plans and estimate Quality, Cost and Delivery (QCD) have been created. The reliance on QCD metrics in process planning neglects the importance of tacit knowledge that people use to make everyday decisions and express their professional judgement in design. Hence, the research also advances the core aggregate planning theories by developing knowledge-enrichment methods for measuring and analysing qualitative factors as an additional indicator of manufacturing performance, which can be used to compute the potential of a process plan. The application of these methods allows the designer to make a comparative estimation of manufacturability for design alternatives. Ultimately, this research should translate into significant reductions in both design costs and product development time and create synergy between the product design and the manufacturing system that will be used to make it. The efficacy of the methodology was proved through the development of an experimental computer system (called CAPABLE Space) which used real industrial data, from a leading UK satellite manufacturer to validate the industrial benefits and promote the commercial exploitation of the research

Preliminary design enhancement by incorporating set- based design principles and a navigator

The need for improvement of Product Development (PD) processes has been demonstrated by a high demand for the aerospace products to be developed quicker and cheaper. Set-Based Design (SBD) can improve the ability to respond faster to customers’ requirements by developing a set of design solutions for possible future product orders in parallel. In SBD participants practise SBCE (Set-Based Concurrent Engineering) by reasoning, developing and communicating about sets of solutions in parallel. As the design progresses, they gradually narrow their respective sets of solutions based on the knowledge gained. As they narrow, they commit to staying within the sets so that others can rely on their communication (Sobek et al, 1999). This research aims to develop logical guidelines for the selection of the PD tools and methods to enable the effective application of the SBD process model guided by a computerized tool, called ‘SBD Navigator’. An integration of the SBD good practices into the collaborator’s PD processes is believed to reduce the possibility of the negative design iteration and to reduce PD time thus providing financial benefits. Understanding the selection of PD methods and tools within manufacturing companies is a starting point of this research. It reveals main causes of poor incorporation of PD methods and tools in the preliminary design phase that might stop businesses from gaining a full range of benefits out of the SBD process model. As time goes on, PD becomes more difficult to manage due to the necessity of the collaboration among business participants in order to create complex and well integrated products. This research project has employed one of the deliverables from the CONGA (Concept Optimisation of Next Generation Aircraft) project which is the SBD process model customized by the collaborating company – Rolls-Royce plc. The RR-SBD process model is presented in chapter 3. [cont.

Knowledge search for new product development: a multi-agent based methodology

Manufacturers are the leaders in developing new products to drive productivity. Higher productivity means more products based on the same materials, energy, labour, and capitals. New product development plays a critical role in the success of manufacturing firms. Activities in the product development process are dependent on the knowledge of new product development team members. Increasingly, many enterprises consider effective knowledge search to be a source of competitive advantage. This research presents an exploratory case study conducted at an aircraft manufacturer. This investigation uncovered six, empirically derived and theoretically informed, problems to enterprise knowledge search. They have been articulated as (i) the effectual web bandwidth limits search speed; (ii) less relevant search results based on word-frequency recognition models of search engine; (iii) un-useable techniques for enterprise search; (iv) rigour security, reliability, and company policy; (v) poor search performance about unstructured enterprise knowledge; (vi) the lack of tacit knowledge sharing. Existing search methodologies have focused on the internet search, rather than providing effective search for enterprise. This research aim is developed to assist the manufacturing enterprise in meeting the industrial requirements in the following way: a methodology and system that can improve the information and knowledge search performance in new product development process. Based on the exploratory case findings, a knowledge search methodology and system has been developed. Agent technology is used to fulfil the requirements of enterprise search. Some initial tests were conducted to better understand implementation issues and future deployment of the methodology and system in practice
