A novel bi-objective reliable location routing model considering impedance function under demand-side and supply-side uncertainty (A Case study)
Reliable location routing problem considers a location problem and a vehicle routing problem in order to select the optimal location of facilities and at the same time the optimal routes for vehicles considering the unexpected failure for facilities in which, all facilities may fail with a probability. In this paper, a bi-objective mathematical model has been developed to minimize the total cos...
متن کاملDevelopment of a Model for Locating Hubs in a Competitive Environment under Uncertainty: A Robust Optimization Approach
This article explores the development of previous models to determine hubs in a competitive environment. In this paper, by comparing parameters of the ticket price, travel time and the service quality of hub airports, airline hubs are divided into six categories. The degree of importance of travel time and travel cost are determined by a multivariate Lagrange interpolation method, which can pla...
متن کاملUncertainty analysis of space-time prisms based on the moment-design method
Space-time prism (STP) is a key concept in geography that measures the movement of objects in space and time. A space-time prism can be treated as a result of the potential path line revolving around in the three dimensional space. Though the concept has found applications in time geography, research on the analysis of uncertainty in space-time prism, particularly under high degree of nonlinear...
متن کاملModelling potential movement in constrained travel environments using rough space-time prisms
The widespread adoption of location-aware technologies has afforded analysts new opportunities for efficiently collecting trajectory data of moving individuals. These technologies enable measuring trajectories as a finite sample set of time-stamped locations. The uncertainty related to both finite sampling and measurement errors make it often difficult to reconstruct and represent a trajectory ...
متن کاملModelling Visit Probabilities within Space-Time Prisms using Directed Random Walk and Truncated Brownian Bridges
The space-time prism demarcates locations that a mobile object can occupy given origin and destination anchors, the earliest origin departure and the latest destination arrival time, and the maximum travel velocity n Lenntorp 1976). The prism boundary has been used widely to delimit individual ’ accessibility (Miller 1991, Kwan 1998, Geurs and Wee 2004). However, little attention has been paid ...
