- 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.
- A contribution for the development of new resources selection models for the agile/virtual enterprisesPublication . Ávila, Paulo; Putnik, Goran; Cunha, MariaThe process of resources systems selection, takes an important part in Agile / Virtual Enterprises (A/V E) integration because the efficient resources selection, or resources systems selection, running in useful time and cost and with efficient solution, is an important operation within the A/V E design phase and certainly will contribute for the flexibility of an A/V E within the phase of its reconfiguration. The resources systems selection is a difficult matter to solve in A/V E 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 requirements that have originate the creation of a specific resources selection model for each one of them. This kind of selection approach models will be reviewed from literature and analyzed its limitations and the consequent necessities of development new ones. At the first time we identified necessities that never were thought before, like performance measures for the selection model, and the necessities of identifying the sponsor for the selection process. We will see too that the models fit uniquely the requirements of a unique A/V E are rigid and not flexible enough to satisfy the requirements of another A/V E. These limitations that we highlight in this work are important to be considered in the development of new models and were simultaneously considered in the development of our selection model for the project of the BM_Virtual Enterprise.
