This study was developed to understand how tourists feel after dreamed travel experiences ended up cancelled. The orchestra model that considers as an intermingled process applied analyse the negative feelings experienced by during these pandemic times. Through web scraping, over 40 thousand comments from 600 threads discussing impact on tourists’ inability concretize their dreams were extracte...

• Travel Intention was critically complicated by numerous factors linked to COVID-19. We empirically validate Intention, Craving and Vaccine Confidence. unlike Craving, has no relationship with discuss implications for theory marketing communication strategies.

Orienteering problems (OPs) are a variant of the well-known prize-collecting traveling salesman problem, where the salesman needs to choose a subset of cities to visit within a given deadline. OPs and their extensions with stochastic travel times (SOPs) have been used to model vehicle routing problems and tourist trip design problems. However, they suffer from two limitations – travel times bet...

We present a case study of a multimodal routing system that takes into account both dynamic and stochastic travel time information. A multimodal network model is presented that makes it possible to model the travel time information of each transportation mode differently. This travel time information can either be static or dynamic, or either deterministic or stochastic. Next to this, a Dijkstr...

We study a vehicle routing problem with soft time windows and stochastic travel times. In this problem, we consider stochastic travel times to obtain routes which are both efficient and reliable. In our problem setting, soft time windows allow early and late servicing at customers by incurring some penalty costs. The objective is to minimize the sum of transportation costs and service costs. Tr...

We consider the problem of allocating long-term delivery time windows to customers in the context of vehicle routing operations. Once the time windows have been assigned, the distributor must attempt to meet them on a daily basis as well as possible. Given that operational parameters, such as customer demands or travel times, vary from day to day, assigning time windows in a way that minimizes ...
