Scheduling problems are NP – Hard combinatorial optimization problems, since many algorithms have been developed which offers new promising insights for solving resource allocation problems. Considering the problems faced in automobile repair shops, who sets the customer due dates of the car based on processing time, jobs already waiting for processing and mechanic available time. Also the work...
The concept of flow has become particularly important in logistics and freight distribution. From a simple question of capacity, the issues of timing, frequency and punctuality are now of significant relevance in freight movements since they are part of supply chain management strategies. In particular, transport terminals and freight distribution centers have been the major elements permitting...
Problems in urban areas at present are caused by the high traffic volumes of motor vehicles. Changing commercial behaviour into e-commerce reduces need for individual customers to visit shopping centres and increases freight transport geographically dispersed consumers. In this case, one solution reduce number lorry journeys may be collection points, such as a network parcel lockers. However, u...
Marketing and management measures – often colloquially know as ‘soft’ measures – can encourage a shift from car travel to more sustainable transport modes, and may also increase public support for direct actions to limit car use. These measures are often effective because many people lack information about alternatives to the car, even for journeys where good alternatives already exist. Other p...
The inefficiencies arising from increased freight road traffic in the late 1990s in Mexico have posed to planners engaged in the road provision the goal to find new control measures to reduce the adverse impacts, such as road damage and overloading. In the 1990s, road freight traffic in Mexico altered notably after the deregulation of the road freight industry in 1989; the North American Free T...
The aim of this paper is to apply a new categorisation algorithm to an existing database of case studies in order to investigate its effectiveness in sorting unknown train vibration signals into freight and passenger train categories for exposure-response analysis. Relatively little work has been performed on the human response to vibration from railway transportation when compared with respons...
Freight movement is a dynamic process involving with complex interaction among many agents by which the commodities are flowed through supply chains. Simulation based model allows such dynamic and complex interaction system to be undertaken. Simulation based multi-agent approach is therefore utilized to model the behaviors of agents and their interactions in supply chains in order that the mech...
in this paper, we develop a freight transportation model for railway network considering hazmat transportation issue. in the transportation system considered, different customers can request for carrying hazmat and non- hazmat boxes. it is assumed that the sequence of the trains in the network is known. the objective is assigning the non-hazmat boxes and hazmat boxes to wagons of the trains so ...
