Abstract

In this paper the E-JABAT-based A-Team architecture for solving multi-mode resource-constrained project scheduling problem with minimal and maximal time lags (MRCPSP/max) is proposed and experimentally validated. MRCPSP/max, also known as MRCPSP-GPR (MRCPSP with generalised precedence relations), belongs to the NP-hard problem class. To solve this problem an asynchronous team of agents implemented using JABAT middleware has been proposed. Three kinds of optimization agent has been used. Computational experiment involves evaluation of optimization agent performance within the A-Team. The paper contains the MRCPSP/max problem formulation, description of the proposed architecture for solving the problem instances, description of optimization algorithms and the discussion of the computational experiment results.
