On the Performance Estimation and Resource Optimisation in Process Petri Nets 2013 Access copy available to the general public Unrestricted Many artificial systems can be modeled as discrete dynamic systems in which resources are shared among different tasks. The performance of such systems, which is usually a system requirement, heavily relies on the number and distribution of such resources. The goal of this paper is twofold: first, to design a technique to estimate the steady-state performance of a given system with shared resources, and second, to propose a heuristic strategy to distribute shared resources so that the system performance is enhanced as much as possible. The systems under consideration are assumed to be large systems, such as service-oriented architecture (SOA) systems, and modeled by a particular class of Petri nets (PNs) called process PNs. In order to avoid the state explosion problem inherent to discrete models, the proposed techniques make intensive use of linear programming (LP) problems. info:eu-repo/grantAgreement/ES/CICYT-FEDER/DPI2010-20413 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 2.169 2013 COMPUTER SCIENCE, CYBERNETICS 4 / 22 = 0.182 2013 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-7093-228X Júlvez, Jorge Universidad de Zaragoza (orcid)0000-0002-8917-6584 Merseguer, José Universidad de Zaragoza 5007 570 Universidad de Zaragoza Departamento de Informática e Ingeniería de Sistemas Lenguajes y Sistemas Informáticos 43, 6 (2013), 1385-1398 IEEE trans. syst. man cybern., Syst.
