Integrating arrival time estimation in truck scheduling: an explorative study in grocery retailing

This paper studies a new managerial approach that integratespredictive trucks’ estimated time of arrival (ETA) into truck schedul-ing to deal with the truck arrival time uncertainty. The approachexploits ETA to reschedule trucks by the up-to-date information andaims to minimize the trucks’ waiting time. The approach wasapplied in a real case. Results quantified the impact of adoptingETA for truck scheduling, also showing how the ETA accuracy andpeak truck arrival rate affect the total trucks’...

Developing a Method to Evaluate Public Space Perception in River Valley Plain Villages of the Loess Gully Area Based on Villagers’ Perspectives

The natural conditions in the loess gully area are harsh, and the construction of rural public spaces often lacks scientific guidance. It is essential to develop an optimization method for public spaces that is oriented toward the needs of villagers. For this study, the numerous river valley plain villages in Northern Shaanxi were selected as typical examples, with a focus on Liangqu Village as a case study. First, a public space perception evaluation system was established using the sema...

On-line inspection of lattice structures and metamaterials via in-situ imaging in additive manufacturing

As advanced production capabilities are moving towards novel types of geometries as well as higher customization demands, a new and more efficient approach for process and part qualification is becoming an urgent need in industry. The layerwise nature of additive manufacturing (AM) potentially allows anticipating qualification tasks in-line and in-process, aiming at reducing the time and costs devoted to post-process inspections, enabling at the same time an early detection of defects since t...

Smart technologies for retailing: who, what, where and why

Purpose: The retail landscape is dramatically changing due to a series of socio-economic and technological challenges, which can be faced through the adoption of smart technologies. Accordingly, a significant number of publications in this field have been produced, albeit with fragmented results. Therefore, this paper aims at both providing a clear and organised overview of the main smart technologies for physical retailing, in terms of application fields and expected impact, while identifyin...

Adaptive VEM for variable data: convergence and optimality

We design an adaptive virtual element method (AVEM) of lowest order over triangular meshes with hanging nodes in 2d, which are treated as polygons. AVEM hinges on the stabilization-free a posteriori error estimators recently derived in Beirão da Veiga et al. (2023, Adaptive VEM: stabilization-free a posteriori error analysis and contraction property. SIAM J. Numer. Anal., 61, 457–494). The crucial property, which also plays a central role in this paper, is that the stabilization term can be m...
