for last years, the evolution of new issues has incited a great development of the transportation system. in this paper, we discuss ingredients of its (intelligent transportation system) that are inter-vehicle communication (ivc) or what can call vehicular ad hoc networks (vanet), which are special type of manet. we will survey the main issues relevant to vanet in detail with providing a concep...

Transportation problems appear in many practically highly relevant areas of our daily life. In this work we deal with a generalized variant of the classical Vehicle Routing Problem (VRP), namely the Periodic Vehicle Routing Problem with Time Windows (PVRPTW), for which only few specific solution techniques have been described in the literature. The basis forms the VRP which is defined on a comp...

Container movement involves several stakeholders where each group is focused on achieving its own objectives. By actively considering the perspective of different maritime stakeholders, this paper identifies a set of implementation strategies and prioritizes them to successfully implement an ‘Inland-Depots-for-Empty-Containers’ (IDEC) system in a region. It builds on the authors’ earlier work t...

This paper examines a practical transportation model known as the Open Vehicle Routing Problem (OVRP). OVRP aims at designing the minimum cost set of routes originating from a central depot for satisfying customer demand. Vehicles do not need to return to the depot after completing their delivery services. In methodological terms, we propose an innovative local search metaheuristic which examin...

Providing appropriate home health care is one of the increasing concerns in organizations. Home Health Care provides various services for disabled or elderly individuals at their homes. Also, deal with current critical situation coronavirus disease (COVID-19) due to limited capacity hospitals and feeling insecurity crowded places, more recommended. This paper addresses a Routing Scheduling Prob...

Long protocol of Gonadotropin-Releasing Hormone-analougue (GnRH-a) can result in the formation of ovarian cyst by the transient initial stimulatory effect which increases the levels of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These cysts require surgical drainage or result in poor ovarian response. Ovarian cyst formation can be prevented by taking oral contraceptive...

In China, rapid economic growth and increasing foreign direct investment (FDI) is the driving force for urbanization, and transformation of urban spatial structures and transportation. Frequent interactive economic activities among the neighboring cities reinforce the already spatially clustered cities. In this paper we tried to extract the key urban transportation characteristics of seventy ma...
