An enhanced ant colony optimiser for multi-attribute partner selection in virtual enterprises

Increasing global competition drives enterprises, especially small and medium-sized enterprises, to collaborate in order to respond faster to customers’ needs, reduce operating costs, increase capacity, and produce customised products to reach the market quicker. A virtual enterprise (VE) is an important manufacturing paradigm to address this trend in the dynamic global economy. Partner selection is a key issue tightly coupled to the success of a VE coalition, and because of its complexity, it is considered a multi-attribute optimisation problem. In this paper, an enhanced ant colony optimiser (ACO) is proposed to address the partner selection problem. Five attributes (namely, cost, time, quality, reputation, and risk) considering both qualitative and quantitative aspects have been investigated to evaluate the candidate partners. Experiments have been conducted to validate the performance of the enhanced ACO algorithm, and the results show that the enhanced ACO algorithm can produce better results in terms of search accuracy and computing time.

Identification of the domain of opportunities for a market of resources for virtual enterprise integration

In the aggressive and competitive business environment of today, enterprises are expected to achieve competitive advantages in synergy, under the format of reconfigurable global networked structures, such as the virtual enterprise (VE) organizational model, integrating the optimal resources (products, operations, services) for each of the functions that the enterprise undertakes, in order to produce a product that meets the market requirements. The literature shows that several Internet-based tools can be used to enable some activities of VE integration. However, as we demonstrate, these do not support the reconfiguration dynamics required by this organizational model. Alternatively, the authors propose the market of resources (MR) as an environment to fully support VE integration, coping with its intrinsic requirement of high reconfigurability. Based on a demonstrator developed for the MR and on cost models traducing VE integration, one for the (traditional) Internet-based tools and the other for the MR, to support an analytical simulation, the paper validates the thesis that the traditional tools cannot support agility and dynamics, presenting the MR as a VE enabler, and identifying the domain of situations where the utilization of the MR reveals increased efficiency in terms of search and selection time and cost—designated as opportunities domain.     

A distributed virtual factory in agile manufacturing environment

There is a growing recognition that current manufacturing enterprises must be agile, that is, capable of operating profitably in a competitive environment of continuously changing customer demands. The use of a virtual enterprise (VE) is becoming increasingly prevalent, and that has been made possible, in part, due to the significant advances in communication and information technology in recent years. A manufacturing system is one of the competitive factors that forms an effective VE. Therefore, for manufacturers wishing to obtain a contract in VE, it is crucial to present attractive and competitive offers to other coalition members. There are several criteria to these offers, such as cycle time, fulfilment of due date or quick shipping date, cost, and quality assurance for the ordered products. Manufacturing system simulation could endorse the basic estimates of the criteria for the strategic offer. The distributed simulation model concept provides practical solutions to facilitate such a large-scaled precise simulation model in the VE environment, because it is constructed as the integration of several manufacturing simulation models of each production module in the factory. As a solution to realize this integration, we propose a Distributed Virtual Factory (DVF) concept that consists of distributed precise simulation models connected by several synchronization mechanisms named Time Bucket algorithms. A DVF enables precise evaluations of the whole manufacturing system, especially in terms of the material flows. In this study, we introduce an Activity Based Costing (ABC) method into the DVF architecture to estimate the detailed cost analysis of the products. The methodology facilitates strategic enterprise management to prepare the request for the bids in the VE environment. The effectiveness of the proposed concept in agile manufacturing is discussed with simulation experiments.     

The role of Bill of Materials and Movements (BOMM) in the virtual enterprises environment

Organizing and managing dynamic networks of enterprises (or virtual enterprises (VE)) is a very complex task and many issues are still to be effectively covered. Apart from the models that can be used to create and manage VEs, product data play a central role in the VE life cycle. VE composition, interaction among VE members (Autonomous Production Systems in this work), as well as its relationship with the market, is severely dependent on the product technical specifications as well as on the product process planning information. In traditional managing systems for the single enterprise environment the Bill of Materials (BOM) plays that role and in this paper is proposed a Bill of Materials and Movements (BOMM) as its equivalent in VE environments. The BOMM includes product structure, high level process planning information and some degree of VE composition. BOMM is present during VE formation, operation, and reconfiguration, playing a central role in the material detailed planning and in the movement planning between VE members. In this article the BOMM role during the VE life cycle is described in detail.     

Integrating failure analysis and risk analysis with quality assurance in the design phase of medical product development

Today, manufacturing operates as a global network, which has created more awareness of the quality of products and services. A systematic and rational way of managing quality assurance is currently lacking. This can cause serious problems in sectors such as the medical industry, as product failure may not only cause time delays, but also create risks for the health and safety of patients and users. This paper proposes a quality assurance approach that incorporates risk analysis (based on ISO14971) and failure analysis (based on FMEA) into the product design phase to assure product quality in the short term and facilitate global manufacturing practices in the long run. The proposed approach includes a Markov model to predict product failure from a customer perspective, which serves as a checkpoint for feedback to provide a basis for quality assurance. A medical equipment firm is used as a test-bed to illustrate how the proposed approach works and to verify its effectiveness.
