In this paper, a new approach to auction based dispatch algorithm in a deregulated power system using differential evolution technique is presented. In a deregulated power system, the production cost is replaced by seller’s bidden cost function including not only the production cost, but also the market strategy, which may become concave, whereas the conventional economic dispatch (ED) algorith...

Outbound logistics is a crucial field of management. This study considers planning distribution for the poultry industry in Thailand. The goal to minimize transportation cost multi-depot vehicle-routing problem (MDVRP). A novel enhanced differential evolution algorithm (RI-DE) developed based on new re-initialization mutation formula and local search function. mixed-integer programming formulat...

While a great portion of the scheduling literature focuses on time-based criteria, the most important goal of management is maximizing the profitability of the firm. In this paper, the net preset value criterion is studied taking account of linear time-dependent cash flows in single machine and flow shop scheduling problems. First, a heuristic method is presented for the single machine scheduli...

abstract. the main contribution of the current paper is to propose a new effective numerical method for solving the first-order linear matrix differential equations. properties of the legendre basis operational matrix of integration together with a collocation method are applied to reduce the problem to a coupled linear matrix equations. afterwards, an iterative algorithm is examined for solvin...

In the last decade, many heuristic methods have evolved for solving optimization problems that were previously difficult or impossible to solve. These methods include simulated annealing (SA), tabu search (TS), genetic algorithm (GA), differential evolution (DE), evolutionary programming (EP), evolutionary strategy (ES), ant colony optimization (ACO), and particle swarm optimization (PSO). This...
