The Split Delivery Vehicle Routing Problem (SDVRP) allows customers to be assigned to multiple routes. A column generation procedure using a route-based formulation is developed for the SDVRP and computational results are given for thirty-two data sets from previous literature. The SDVRP route-based formulation appears tighter (stronger) linear relaxation than a comparable SDVRP flow formulatio...

An efficient and cost-effective approach in the synthesis process of the bismuth telluride (Bi2Te3) powders and pellets were developed based on a chemical solution route. The route consists of dissolving of both the bismuth (III) nitrate pentahydrate, Bi(NO3)3.5H2O, and tellurium dioxide, TeO2 into the same inorganic nitric a...

Aerodrome ground traffic management consists of many processes. Their complexity causes that telematic solutions intended to assist both the air traffic controller who coordinates taxiing and the pilot who executes them are introduced. An example of such a solution is A-SMGCS system. At the moment, intensive research on advanced system functions are carried out. They include smart taxi route ch...

The Networks Mobility (NEMO) Protocol is a way of managing the mobility of an entire network, and mobile internet protocol is the basic solution for Networks Mobility. A hierarchical route optimization system for mobile network is proposed to solve management of hierarchical route optimization problems. In present paper, we study Hierarchical Route Optimization Scheme using Tree Information Opt...

the passenger line planning is a process of strategic long-term decision-making problem in the field of railway passenger planning. a line is a route between starting point and destination with certain stops, which has a certain frequency of train schedule. a new solution based on decomposition algorithm has been proposed in this paper, which is defined in a master problem and two sub problems....

in this work, modification of carbon paste electrode surface with poly (2, 5-dimethyl aniline) (p-2,5-dma) by using electrochemical polymerization was described. then, transition metal ions of ni(ii) were incorporated into the polymer film by two ways. at first way, the polymeric modified electrode was immersed in 0.2 m niso4 solutions and the second way was carried out by electrodeposition of ...

This article demonstrates preparation of metal functionalized zeolite catalysts via a new homogeneous solution pathway enabled by the recently reported exfoliation MWW into unilamellar nanosheets. The is carried out mixing solutions exfoliated monolayers and Pt nanoparticles with initial size ca 3 nm isolation such hybrid freeze-drying. Optionally, layer were purified dialysis prior to solution...
