Abstract Logistics distribution is a collection of interrelated organizations and facilities. There waste cost time in many links. Therefore, it particularly important to use information technology improve efficiency. Under the constraints delivery vehicle time, this paper proposes an improved genetic simulated annealing algorithm (SAGA), which combines global search ability (GA) (SA) with stro...

With the increasing penetration of photovoltaics in distribution networks, adaptability network under uncertainties needs to be considered planning systems. In this paper, interval arithmetic and affine are applied deal with uncertainties, an based bi-level multi-objective joint model is built, which can obtain schemes low constraint-violation risk, high reliability strong adaptability. On basi...

vendor managed inventory is a continuous replenishment program that is designed to provide major cost saving benefits for both vendors and retailers. previous research on this area mainly included single objective optimization models where the objective is to minimize the total supply chain costs or to maximize the total supply chain benefits. this paper presents a bi-objective mathematical mod...

The optimization of investment portfolios is the most important topic in financial decision making, and many relevant models can be found in the literature.  According to importance of portfolio optimization in this paper, deals with novel solution approaches to solve new developed portfolio optimization model. Contrary to previous work, the uncertainty of future retur...
