Title: UAV/UGV Routing Problem with Partial Charging Strategy
Abstract
With the continuous development of e-commerce, logistics demand has experienced explosive growth, and customer orders have been characterized by multiple batches and small batches. This paper co-ordinates the route and recharging strategies of electric vehicles (EVs); it is different from the basic assumption of full recharging in the previous E-VRP; we model an E-VRP with partial recharging based on the actual situation. The calculation results of an example shows that compared to the full recharging strategy, the vehicle routing cost based on the partial recharging strategy can be reduced effectively.

Title: Toward digital validation for smart manufacturing based on digital twin
Abstract
A digital validation framework of rapid product development for smart manufacturing based on digital twin is proposed. During product development, the new product is designed according to the new requirements in the virtual space, in which the existing digital twins of products can be referenced. Then, an ultrahigh-fidelity virtual manufacturing system is constructed for digital trial manufacturing based on the digital twin of the manufacturing system and the design scheme of the new product. An ultrahigh-fidelity digital prototype can be obtained from digital trial manufacturing for digital validation. The new product validation is executed on the digital proto- type to test its performance. The digital validation results can be used to improve the design scheme of the new product and boost the corresponding manufacturing processes. Finally, a case study is presented to show the effectiveness of the proposed framework.

Title: Application of digital twins in monitoring of complex transient welding manufacturing process
Abstract
Welding is an important material forming and processing technology in modern manufacturing industry, which is widely used in aerospace, rail transit, ocean engineering, energy and other fields. At present, welding intelligence is one of the most challenging research hotspots in the manufacturing field. The report introduces the development status of advanced welding process monitoring technology and analyzes the problems existing in traditional monitoring methods. Then, the monitoring method of welding process driven by digital twin is put forward, and the framework, implementation scheme and technical difficulties of welding process digital twin model are discussed. Finally, the realization method of welding digital twin system and its application cases are introduced, and its future development direction is prospected.
