Multicommodity distribution problem is one of the most interesting and useful models in mathematical programming due to its major role in distribution networks. The purpose of this paper is to describe and solve a special class of multicommodity distribution problems in which shipment of a commodity from a plant to a customer would go through different distribution centers.

The entry price of supercomputing has traditionally been very high. As processing elements, operating systems, and switch technology become cheap commodity parts, building a powerful supercomputer at a fraction of the price of a proprietary system becomes realistic. We have recently purchased, in support of both our local and national collaborations, a dedicated computational cluster of eight D...

in this study, the situation of iran, u.s and turkey's pistachio export is investigated. to this purpose, revealed comparative advantage (rca) index is calculated based on agricultural and total economy export, separately, then forecasted by using auto- regressive integrated moving average (arima) approached, for 2008-2013. the results show that considering both commodity baskets, turkey a...

The capacitated arc routing problem (CARP) is one of the most important routing problems with many applications in real world situations. In some real applications such as urban waste collection and etc., decision makers have to consider more than one objective and investigate the problem under uncertain situations where required edges have demand for more than one type of commodity. So, in thi...

This paper investigates the heterogeneous dependence between global crude oil futures and China’s biofuel feedstock commodities under different market conditions. Quantile-on-quantile regression causality-in-quantiles test are employed to capture comprehensive informative relationships. The empirical results as follows: First, there is a positive relationship returns on oil. effects heterogeneo...

With the increasing openness of China economy, goal this paper is to examine volatility connectedness and spillover transmissions across markets for stock, public real estate, bond, commodity futures, foreign exchange within economy. Over full study period, we find that five China's financial are not strongly connected. The bond market predominant transmission, whereas futures top ne...

The debate on smallholder commodification trajectories tends to be polarised between mainstream approaches that advocate tighter integration of smallholders into global value chains, and alternative favour localised markets the grounds these provide greater autonomy over production marketing, allow a share realised for producers wider community. This obscures interrelations possible synergies t...
