- Broker and Market of Resources as Organizational Mechanisms for Sustainability of Resources Selection Processes In Agile / Virtual EnterprisesPublication . Ávila, Paulo; Putnik, Goran; Cunha, Maria; Pires, AntónioOur Agile / Virtual Enterprises (A/V E) model, it is associated with the creation of temporary net of several physical organizations (or resources), with the intention to develop and produce one or more products/services, in the quantity and quality desirable, answering rapidly to a market solicitation. Our model has to satisfy four functional requirements: virtuality, distributivity, integrability and agility. The main mechanisms, or tools, for assuring satisfaction and implementation of these requirements, by the Virtual Enterprises Architecture Reference Model (BM_VEARM), are the Broker, the Market of Resources and the virtuality (as the specific organization architectural, or structural, pattern). In this paper, Broker and Market of Resources, and their roles and relationship within the process of resources selection, as one of the main processes of the A/V E as well as one of the “agility” processes, are considered. Both of them, Broker and Market of Resources, are independent physical entities, with own juridical identification, that inter-working between them and the Principal (the mentor of a business opportunity), could origin an A/V E creation. We will show in this article the main functions and its organizational position, associated to the triple Broker – Resources Market – Principal, for the A/V E configuration and operation. For the resources system selection those functions will be more detailed explained and identified its tools or type of tools, and its desired performance to assure the A /V E integrability and agility. One of these kinds of tools, are expected to be quality assurance tools, namely the value analyses.
- An algorithm of a costing system for electroplatingPublication . Pires, António; Ferreira, Fábio; Ávila, Paulo; Mota, AlziraBusinesses are increasingly competitive and rigorous and it is essential the existence of a strong, effective and realistic costing system. Decisions taken on the basis of the costing are very important, they can make the difference between success and failure of the organization. This paper explains the construction of an initial algorithm that aims to calculate the costs associated with electroplating of metal articles, in a specific company. This work can act as a possible guide for the construction of the costing system algorithms in this type of industry.
- Domain of applicability of Value Analysis approach in the pre-selection of resourcesPublication . Pires, António; Putnik, Goran; Ávila, PauloFor the project of an Agile/Virtual Enterprise (A/V E) the resources selection is a key factor. The output of the selection process should be prepared to guarantee quality, efficiency and cost-attractiveness, in order to ensure the agility and integrability of the A/V E. Despite the potential of Value Analysis (VA), none of the resources selection models found in the literature incorporates the VA integration. The main objective is to quantify the selection process performance with VA integrated into the pre-selection of resources in accordance with the developed model. The paper presents through the simulation results analysis, some of the benefits of VA application: greater applicability domain for candidate resources and number of tasks; and reduction of the selection time.
- An Evolutionary Based Algorithm for Resources System Selection Problem in Agile/Virtual EnterprisesPublication . Ávila, Paulo; Pires, António; Madureira, Ana MariaThe problem of resources systems selection takes an important role in Agile/Virtual Enterprises (A/VE) integration. However, the resources systems selection problem is difficult to solve in A/VE because: it can be of exponential complexity resolution; it can be a multi criteria problem; and because there are different types of A/V Es with different requisites that have originated the development of a specific resources selection model for each one of them. In this work we have made some progress in order to identify the principal gaps to be solved. This paper will show one of those gaps in the algorithms area to be applied for its resolution. In attention to that gaps we address the necessity to develop new algorithms and with more information disposal, for its selection by the Broker. In this paper we propose a genetic algorithm to deal with a specific case of resources system selection problem when the space solution dimension is high.
