Virtual cities management and organisation
This paper presents a recent overview of the increasing use of Virtual Reality (VR) technologies for the simulation of urban environments. It builds on previous research conducted on the identification of three-dimensional (3D) city models and offers an analysis of the development, utilization and construction of VR city models. Issues pertaining to advantages, barriers and ownership are identified. The paper describes a case study of the development of a VR model for the city of Newcastle upon Tyne in the UK and outlines the role that academic institutions can play in both the creation and utilization of urban models. The study offers a new approach for the creation, management and update of urban models and reflects on issues which are emerging. Areas for future research are discussed

Analysis and Design of Intelligent Logistics System Based on Internet of Things
Based on Internet of things, .NET software development technology and GIS technology, this paper analyzes and designs a system of intelligent distribution information with software engineering life cycle theory as the guide to solve the problem of high complexity and low efficiency of manual operation in logistics and distribution, improve the level of intelligent operation and then improve the operating efficiency. It analyzes the business requirements of the system, then designs its physical architecture, software architecture and system structure, and constructs the terminal node distribution dynamic model of transmission route, realizing the main function modules of the system and verifying the correctness and effectiveness of the system results through systematic and comprehensive tests.

Optimizing Indoor Navigation Policies For Spatial Distancing
In this paper, we focus on the modification of policies that can lead to
movement patterns and directional guidance of occupants, which are represented
as agents in a 3D simulation engine. We demonstrate an optimization method that
improves a spatial distancing metric by modifying the navigation graph by
introducing a measure of spatial distancing of agents as a function of agent
density (i.e., occupancy). Our optimization framework utilizes such metrics as
the target function, using a hybrid approach of combining genetic algorithm and
simulated annealing. We show that within our framework, the
simulation-optimization process can help to improve spatial distancing between
agents by optimizing the navigation policies for a given indoor environment.Comment: 9 pages, 8 figures, conference-- simulation in architecture and urban
