Common Goals

Abstract Integrated Product Process Development is essential to the development of competitive products, with manufacturing considerations such as cost, quality and cycle times well understood early in the design cycle. In order to rapidly design and develop new products, diverse organizations, often separated by hundreds of miles, must find new ways of sharing ideas and knowledge and working together towards common goals. New tools must be inserted into the process to enable and facilitate a different way of doing business. This paper summarizes work performed as part of the DARPA sponsored Rapid Design Exploration and Optimization (RaDEO) program, specifically the development of the Manufacturing Simulation Driver (MSD) system which demonstrates the automatic generation and execution of distributed manufacturing simulations. The MSD system enables Integrated Process Teams (IPT’s) to quickly create detailed manufacturing simulations of new products. MSD driven simulations include modeling the flow of a product through a particular factory early in the design cycle to provide the insight to modify designs in order to alleviate manufacturing bottlenecks. This capability enables emerging virtual enterprises conducting collaborative design and manufacturing to simulate and prove out the manufacturing cycle of a product prior to launching production ramp-up. The Manufacturing Simulation Driver (MSD) system automatically populates simulatable manufacturing templates enabling manufacturability assessments of alternative candidate designs and processes to be conducted throughout the product development cycle. This capability provides design teams with early insight into aspects of the evolving design which compromises product manufacturability.

Abstract Integrated Product Process Development tools which minimize downstream manufacturing risk at the earliest design stages and avoid costly Design-Build-Test cycles are essential to achieving product profitability and meeting market windows. This paper summarizes initial work performed towards the development of the Manufacturing Simulation Driver (MSD) system which will demonstrate the automatic generation and execution of distributed manufacturing simulations. These simulation models are produced by Computer Aided Process Planning (CAPP) software tools which reason about Computer Aided Design (CAD) product models and produce manufacturing “scripts” from a process and resource model of a manufacturing facility. This capability will enable emerging virtual enterprises conducting collaborative design and manufacturing to simulate and prove out the manufacturing cycle of a product prior to launching production ramp-up. 1

Strong Incentive

Traditional electromigration life testing is a time-consuming and often painful process, consuming many expensive samples and weeks of valuable time to collect enough data for a statistically significant conclusion. Annoying, to say the least, this often causes real problems in process development when cycle times of new products can often be measured in months. Therefore, there has been a strong incentive to search for alternatives.

Intensifying electronic component power dissipation levels, shortening product design cycle times, and greater than before requirement for more compact and reliable electronic systems with greater functionality, has heightened the need for thermal design tools that enable accurate solutions to be generated and quickly assessed. The present numerical study aims at developing a computational tool in OpenFOAM that can predict the heat dissipation rate and temperature profile of any electronic component in operation. A suitable computational domain with defined aspect ratio is chosen. For analyzing, “buoyant Boussinesq Simple Foam“ solver available with OpenFOAM is used. It was modified for adapting to the investigation with specified initial and boundary conditions. The experimental setup was made with the dimensions taken up for numerical study. Thermocouples were calibrated and placed in specified locations. For different heat input, the temperatures are noted down at steady state and compared with results from the numerical study.

The Impact

Purpose This paper aims to develop a framework for switching a service supplier in a supply network. Design/methodology/approach The study builds on existing literature in the field of purchasing and supply management, public procurement (PP) and the Industrial Marketing and Purchasing approach, as well as on an illustrative example case, from the PP context, of a supplier switch in a service delivery process. Findings During a switching process, the buyer must simultaneously manage the ending of a relationship with the incumbent supplier and the beginning of a relationship with a new supplier. Collaboration with the focal suppliers to develop a service process with standardized components prevents disruptions in the service processes and reduces the impact of the switch on the wider network. Research limitations/implications The conceptualization suggested in this paper needs to be further explored in different empirical contexts to assess its practical adequacy. Practical implications Practitioners responsible for service procurement can use the findings to develop collaboration with suppliers, both when it comes to service process development and to the switching process. Furthermore, the authors highlight the importance of ending competencies and the development of an exit plan to conduct a “beautiful exit.” Originality/value The paper integrates relationship initiation and ending studies, as well as procurement process models to develop a refined switching process framework. Many PPs rely on short-term relationships due to the legal obligation to frequently invite suppliers to tender, thus understanding the supplier switching process is important both for private and public sector actors.

Small, Medium, and Micro enterprises (SMMEs) usually do not have adequate funds to acquire ICT infrastructure and often use cloud computing. In this paper, the authors discuss the implementation of virtual enterprises (VE) to enable SMMEs to respond quickly to customers’ demands and market opportunities. The virtual enterprise model is based on the ability to create temporary co-operations and realize the value of a short term business opportunity that the partners cannot fully capture on their own. The model of virtual enterprise is made possible through virtualisation technology, which is a building block of cloud computing. To achieve a common goal, enterprises integrate resources, organisational models, and process models. Through the virtual business operating environment offered by cloud computing, the SMMEs are able to increase productivity and gain competitive advantage due to the cost benefit incurred. In this paper, the authors propose a virtual enterprise enabled cloud enterprise architecture based on the concept of virtual enterprise at both business and technology levels. The business level comprises of organisational models, process models, skills, and competences whereas the technology level comprises of IT resources.
