Multi-objective robust optimisation model for MDVRPLS in refined oil distribution
نویسندگان
چکیده
At depots with refined oil shortage, arranging a reasonable distribution scheme limited supply affects operation costs, demand satisfaction rate of gasoline stations (hereafter, ‘station satisfaction’), and overtime penalty. This study considers the problem shortages using multi-objective optimisation approach from perspective decision makers marketing companies. The modelling solving process involves (i) formulation crisp multi-depot vehicle routing model (MDVRPLS) which station priority soft time windows, (ii) development robust (ROM) to manage uncertainty in demand, (iii) proposal particle swarm (MOPSO)algorithm. Results numerical experiments show that can better balance satisfaction, penalty, produces 3.33% 4.60% increase at an increased unit cost penalty respectively; ROM successfully addresses compared model, requires additional 8.81% 12.85% penalty; MOPSO manages these MDVRPLS models more effectively than other heuristic algorithms. Therefore, applying shortage management significantly improves efficiency resists disturbance caused by external uncertainties, providing scope for efficient scarce resources.

Multi-objective Optimisation of Power Restoration in Electricity Distribution Systems
This paper proposes a new multi-objective approach for the problem of power restoration in (n-1) contingency situations. It builds on a previous, mono-objective approach introduced in Mendes et al. (2010) [14]. Power restoration normally relies on network reconfiguration, and typically involves re-switching and adjustment of tap-changers and capacitor banks. In this work, we focus on re-switchi...
