- 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.
- Resources selection for agile/virtual enterprises part il - prototype/demonstrator toolPublication . Castro, Álvaro; Pires, António; Costa, Lino; Putnik, Goran; Ávila, PauloThe process of creation/development of an AN E is not simple. Due to the large number of potential resources is important to make a selection of those who give more guarantees in terms of success in this cooperation and bring more value to A/V E. There are several projects of AN E with different approaches to the selection process. The Virtual Enterprise Architecture Reference Model (BM VEARM) project incorporates a model of resource selection. Considering the aspects of the model the main objective is the development of a tool for pre-selection of resources in MATLAB, and its integration with an algorithm for the final selection. The result is the tool named Selec_E AN V2 with the following features: Pre-selection of resources without integration of the Value Analysis (VA), with integration of VA and final selection of resources given to those mentioned cases. This tool will support the development of BM_VEARM selection model and will permit the validation of the importance of VA in the resources pre-selection.
