Plug-in hybrid electric vehicle (PHEV) technology is receiving attention as an approach to reducing U.S. dependency on foreign oil and emissions of greenhouse gases (GHG) from the transportation sector. Because plug-in vehicles require large batteries for energy storage, battery weight can have a significant impact on vehicle performance: Additional storage capacity increases the range that a P...

Big promotions of online retailers in different shopping festivals often lead to an overwhelming demand surge parcel delivery. Besides using its own distribution capacity, usually adopt capacity sharing cope with the surge. Because low cost unmanned distribution, can vehicle (UVD) capability sharing. We examine retailer’s UVD strategies a logistics firm under develop models unilateral and bidir...

Theoretical analyses of a set of iterated-tour partitioning vehicle routing algorithms applicable to a wide variety of commonly-used vehicle routing problem variants are presented. We analyze the worstcase performance of the algorithms and establish tightness of the derived bounds. Among other variants we capture the cases of pick-up and delivery, and multiple depots. We also introduce brand ne...

Vehicular ad hoc networks are an important new class of wireless networks with applications ranging from safety and crash avoidance to Internet access and multimedia distribution. In this article, an efficient method of message dissemination using rateless coding is proposed. Both vehicle-to-vehicle and vehicle-to-infrastructure data transfer are allowed. By employing rateless coding at road si...

Vehicle routing problems attempt to define optimal delivery methods of goods to places. I examined the capacitated vehicle routing problem that determines the least cost route to deliver objects to customers using a single vehicle of fixed capacity. Vehicle routing problems attract considerable attention because of their implications for delivery businesses. My variant of the problem differs fr...

In this paper, we propose a procedure, based on statistical design of experiments and gradient descent, that finds effective settings for parameters found in heuristics. We develop our procedure using four experiments. We use our procedure and a small subset of problems to find parameter settings for two new vehicle routing heuristics. We then set the parameters of each heuristic and solve 19 c...

background boswellia serrata has been used in a wide variety of diseases, including diabetes mellitus and inflammatory diseases. objectives this study focused on the effects of boswellia serrata aqueous extract on blood glucose and the complications of diabetes in the liver and kidneys and examined the impact of plant on reproduction in diabetic rats. materials and methods the antioxidant capac...

the capacitated vehicle routing problem (cvrp) is a well-known combinatorial optimization problem that holds a central place in logistics management. the vehicle routing is an applied task in the industrial transportation for which an optimal solution will lead us to better services, save more time and ultimately increase in customer satisfaction. this problem is classified into np-hard problem...

The capacity of public roads has become a serious problem all over the world. The traffic is constantly increasing, while the capacity remains almost the same. This causes traffic jams and road accidents. An effective way to increase the road throughput employs vehicular platoons, which allow to decrease inter-vehicle distances without compromising road safety. The urgent necessity to increase ...
