Scatter search algorithm (SSA) and shuffled frog leaping algorithm (SFLA) are two intelligent optimization algorithms. SSA was introduced to solve discrete optimization problems in 1977 and SFLA in 2003 was created for solving continuous optimization problems. Currently, These two algorithms had already been wildly applied to solving many engineering(More)
The classical Particle swarm optimization (PSO) algorithm is a powerful method to find the minimum of a numerical function, on a continuous definition domain. With more importance being attached to PSO, the application of PSO algorithm to a great deal of different scientific fields have been introduced in many literature. Here, a PSO algorithm is applied to(More)

Coordinating the supply chain is a main object of supply chain management, and an inventory decision model is developed to analyze the coordination of a two-echelon supply chain with one supplier and one retailer. The products in our paper are perishable and sold over a single selling season. After discussing a pure wholesale price contract, we put forward(More)
Consider a two-echelon supply chain with one supplier and one retailer, and the products are perishable and sold over a single selling season. According to the classical newsvendor model, the retailer traditionally can only order products before the selling season. This paper discusses a situation in which the retailer can place a second order in the(More)
