Aiming at the multi-depot heterogeneous vehicle routing problem under time-dependent road network and soft time window, considering fixed cost, window penalty cost transportation an optimization model of is established with objective minimizing distribution cost. According to characteristics problem, a hybrid genetic algorithm variable neighborhood search temporal–spatial distance designed. Cus...

Waste clean-up after a disaster is one of the most critical tasks in response stage management. We develop model to minimise cost and duration waste considering using Temporary Disaster Management Sites (TDWMSs), which can store process before it sent final disposal sites. The problem that arises be seen as Multi-Period Two-echelon Location Routing Problem (MP-2ELRP) main decisions are location...

In previous work on arti cial social systems, social laws for multi-agent mobilization were hand-crafted for particular network structures. In this work, we introduce an algorithm for the automatic synthesis of social laws for multi-agent mobilization in any 2-connected graph environment. We introduce the notion of a graph routing and show that the problem of computing a useful social law can b...

We consider the problem of finding a single-path intra-domain routing for time-varying traffic. We characterize the traffic variations by a finite set of traffic profiles with given non-zero fractions of occurrence. Our goal is to optimize the average performance over all of these traffic profiles. We solve the optimal multi-path version of this problem using linear programming and develop heur...

This paper proposes the first model for toll enforcement optimization on German motorways. The enforcement is done by mobile control teams and our goal is to produce a schedule achieving network-wide control, proportional to spatial and time-dependent traffic distributions. Our model consists of two parts. The first plans control tours using a vehicle routing approach with profits and some side...

Peningkatan kendaraan bermotor berdampak pada peningkatan frekuensi konsumsi BBM, seperti saat weekend, arus mudik. Depot BBM X bertugas mengirimkan ke sejumlah SPBU yang tersebar di wilayah Yogyakarta, diminta untuk dapat menjaga kelancaran dan ketepatan waktu dalam pendistribusiannya segala situasi kondisi. kerap kali berhadapan dengan kendala pengiriman terlalu lama, juga disebabkan oleh rut...
