This paper presents an innovative modeling framework able to support planning, management and optimization of waste collection operations in an urban context. A proprietary simulator composed by three functionality modules (Global Positioning System, Data Mining system, Simulator for routing and resource exploitation) was implemented by the authors, and was then validated on a specific set of case...
Effective scheduling has a significant effect on efficiency in container terminals. This paper proposes a model of tugboat scheduling and applies an improved Discrete Chaos Particle Swarm Optimization (DCPSO) algorithm to solve this problem. DCPSO orders the position vector of particles to get a discrete scheduling solution. Moreover, chaos search can get all the states in the search space by the...
Container terminal handling operation is the main task of terminal service. The handling time and the operation efficiency at container terminals are the service quality evaluation standard in the resource limit. This paper based on the discreteness and dynamic characteristic of Container Terminal Logistics Operation System (CTLOS), establishes the architecture of CTLOS with the multi-agents technology,...
A rolling-horizon approach was proposed, which aims at the problem of berth allocation and quay crane assignment. Then a dynamic allocation model using objective programming was initially developed for berths allocation and quay crane assignment, which more closes realistic as result of basing continuum quayside. The model objective function was subject to the minimization of the total berthing location...
Distribution center is a bridge connecting providers and clients. It plays an important role in logistics system. This paper put forward the least cost and the shortest time allocation models of materials distribution center. The integrated measure allocation models of materials distribution center considering the time and the cost together is built and a solution flow to the least cost and the shortest...
With the development of the global business and logisticspsila a container terminal (CT) system becomes more and more busy. Therefore, the available resources in the sea port get scarcer than before. In order to increase the operating efficiency of CT system, the resources planning problem has become a critical issue in the fields of operations research and logistics. In this paper, we introduce the...
