    Modified Stage-Gate: A Conceptual Model of Virtual Product Development Process

    Get PDF
    In today’s dynamic marketplace, manufacturing companies are under strong pressure to introduce new products for long-term survival with their competitors. Nevertheless, every company cannot cope up progressively or immediately with the market requirements due to knowledge dynamics being experienced in the competitive milieu. Increased competition and reduced product life cycles put force upon companies to develop new products faster. In response to these pressing needs, there should be some new approach compatible in flexible circumstances. This paper presents a solution based on the popular Stage-Gate system, which is closely linked with virtual team approach. Virtual teams can provide a platform to advance the knowledge-base in a company and thus to reduce time-to-market. This article introduces conceptual product development architecture under a virtual team umbrella. The paper describes all the major aspects of new product development (NPD), NPD process and its relationship with virtual teams, Stage-Gate system finally presents a modified Stage-Gate system to cope up with the changing needs. It also provides the guidelines for the successful implementation of virtual teams in new product development

    A Graph-Based Semantics Workbench for Concurrent Asynchronous Programs

    Get PDF
    A number of novel programming languages and libraries have been proposed that offer simpler-to-use models of concurrency than threads. It is challenging, however, to devise execution models that successfully realise their abstractions without forfeiting performance or introducing unintended behaviours. This is exemplified by SCOOP---a concurrent object-oriented message-passing language---which has seen multiple semantics proposed and implemented over its evolution. We propose a "semantics workbench" with fully and semi-automatic tools for SCOOP, that can be used to analyse and compare programs with respect to different execution models. We demonstrate its use in checking the consistency of semantics by applying it to a set of representative programs, and highlighting a deadlock-related discrepancy between the principal execution models of the language. Our workbench is based on a modular and parameterisable graph transformation semantics implemented in the GROOVE tool. We discuss how graph transformations are leveraged to atomically model intricate language abstractions, and how the visual yet algebraic nature of the model can be used to ascertain soundness.Comment: Accepted for publication in the proceedings of FASE 2016 (to appear

    Cell design, management and continuous improvement

    Get PDF
    A cellular manufacturing system is a shop floor that has been organised into groups of dissimilar machines producing groups of similar parts. Each group of machines is called a cell and each group of parts is called a part family. The main advantage of a cellular manufacturing system is low material handling, since ideally, a part need only travel to the cell it belongs to in order to be manufactured. If a cell can manufacture its part family without any member of that part family having to travel to another cell, then that cell is said to be independent. In reality, cells are rarely independent and this causes many complications when trying to design a cellular manufacturing system. To address these complications, a strategy for cell design, management and continuous improvement was developed. This comprises three stages: (i) Determine cell configurations. (ii) Position cells and the workstations within them. (iii) Carry out Capability Analysis to identify targets for continuous improvement. Black Box Clustering is used to determine cell configurations by clustering a workstation-part matrix representation of routings. The Cellect layout tools identify the best position for each cell and the relative positions of the workstations within them based on material handling costs. This data combined with user interaction can be used to identify the precise locations of individual workstations. Capability Analysis is a methodology developed to assess groups of performance measures that should b

    Tese (doutorado) - Universidade Federal de Santa Catarina, Centro TecnologicoO trabalho realizado discute a necessidade de 'Learning Enterprises' para fazer frente às crescentes globalização e customização de produtos e processos assim como a urgente necessidade de uma conscientização ambiental por parte das indústrias de manufatura. É abordada a necessidade de uma revisão da filosofia de produção e das estruturas organizacionais e gerenciais adotadas atualmente pela maioria das empresas do setor de manufatura. Trabalho também inclui um estudo de três elementos que podem ser utilizados como catalisadores para a obtenção de 'Learning Enterprises': Áreas Virtuais de Produção, representando o elemento organizacional, Sistemas Distribuídos de Planejamento Fino, Monitoração e Controle da Produção, como o elemento tecnológico e a 'Human Networking' obtida pelo Gerenciamento da Comunicação Humana, como o elemento necessário para o gerenciamento de sistemas dinâmicos centrados no homem. O resultado do estudo realizado em cada uma das áreas identificadas acima é, então, integrado segundo um procedimento sistemático originando um modelo de referência genérico para a concepção de uma 'Learning Enterprise'. A abordagem apresentada enfoca empresas de manufatura fabricantes de pequenos lotes e de produtos 'one-of-a-kind'

    Concurrent Mission and Systems Design at NASA Glenn Research Center: The Origins of the COMPASS Team

    Get PDF
    Established at the NASA Glenn Research Center (GRC) in 2006 to meet the need for rapid mission analysis and multi-disciplinary systems design for in-space and human missions, the Collaborative Modeling for Parametric Assessment of Space Systems (COMPASS) team is a multidisciplinary, concurrent engineering group whose primary purpose is to perform integrated systems analysis, but it is also capable of designing any system that involves one or more of the disciplines present in the team. The authors were involved in the development of the COMPASS team and its design process, and are continuously making refinements and enhancements. The team was unofficially started in the early 2000s as part of the distributed team known as Team JIMO (Jupiter Icy Moons Orbiter) in support of the multi-center collaborative JIMO spacecraft design during Project Prometheus. This paper documents the origins of a concurrent mission and systems design team at GRC and how it evolved into the COMPASS team, including defining the process, gathering the team and tools, building the facility, and performing studies

    A manufacturing model to support data-driven applications for design and manufacture

    Get PDF
    This thesis is primarily concerned with conceptual work on the Manufacturing Model. The Manufacturing Model is an information model which describes the manufacturing capability of an enterprise. To achieve general applicability, the model consists of the entities that are relevant and important for any type of manufacturing firm, namely: manufacturing resources (e.g. machines, tools, fixtures, machining cells, operators, etc.), manufacturing processes (e.g. injection moulding, machining processes, etc.) and manufacturing strategies (e.g. how these resources and processes are used and organized). The Manufacturing Model is a four level model based on a de—facto standard (i.e. Factory, Shop, Cell, Station) which represents the functionality of the manufacturing facility of any firm. In the course of the research, the concept of data—driven applications has emerged in response to the need of integrated and flexible computer environments for the support of design and manufacturing activities. These data—driven applications require the use of different information models to capture and represent the company's information and knowledge. One of these information models is the Manufacturing Model. The value of this research work is highlighted by the use of two case studies, one related with the representation of a single machining station, and the other, the representation of a multi-cellular manufacturing facility of a high performance company
