In these price-oriented HEM methods, controller timing for energy consumption of home appliances in response to the electricity price signal has multiple priorities among customers. Although various methods have recently been proposed for the use of HEM, pri...
This study aims to forecast Iran's electricity demand by using meta-heuristic algorithms, and based on economic and social indexes. To approach the goal, two strategies are considered. In the first strategy, genetic algorithm (GA), particle swarm optimization (PSO), and imperialist competitive algorithm (ICA) are used to determine equations of electricity demand based on economic and social ind...
We address a generic price competition model in an industry with an arbitrary number of competitors, each offering all or a subset of a given line of N products. The products are substitutes in the sense that the demand volume of each product weakly increases whenever the price of another product increases. The cost structure is linear, with arbitrary cost rates. Our demand model is the unique ...
In this paper, an incentive policy is proposed to coordinate ordering, lead time, and pricing strategies in a two-echelon manufacturing supply chain (SC) consisting of one manufacturer and one retailer. The system is faced with a stochastic demand which depends on both price and lead time. The manufacturer decides on production size and manufacturing acceleration rate while the retailer determi...
One of the major problems in Iranian economy is continuous deficit in the budget operating balance due to the non-optimal government size.
