“…(5) In the job shop, only the processes of the same part have process constraints and there are no process constraints between different parts. (6) The process time of the process includes the preparation time and transportation time of the process. (7) The parts-process workshop processes a batch of parts for the components-assembly workshop and the product-assembly workshop; or the parts-assembly workshop processes certain parts for the assembly station of the product-assembly workshop.…”

“…Smutnicki [5] proposed an approximation algorithm based on tabu search, with the goal of minimizing processing time and studying a mixed flow shop with a limited intermediate buffer area. Wang et al [6] proposed a multi-objective genetic algorithm to study the integrated scheduling problem of flow shop with buffer. Seidgar et al [7] considered the coordination trade-off model of maximum process time and average completion time and used intelligent algorithms to solve and study the optimization of two-stage flow-shop scheduling with assembly tasks.…”

In hybrid mixed-flow workshop scheduling, there are problems such as mass production, mass manufacturing, mass assembly and mass synthesis of products. In order to solve these problems, combined with the Spark platform, a hybrid particle swarm algorithm that will be parallelized is proposed. Compared with the existing intelligent algorithms, the parallel hybrid particle swarm algorithm is more conducive to the realization of the global optimal solution. In the loader manufacturing workshop, the optimization goal is to minimize the maximum completion time and a parallelized hybrid particle swarm algorithm is used. The results show that in the case of relatively large batches, the parallel hybrid particle swarm algorithm can effectively obtain the scheduling plan and avoid falling into the local optimal solution. Compared with algorithm serialization, algorithm parallelization improves algorithm efficiency by 2–4 times. The larger the batches, the more obvious the algorithm parallelization improves computational efficiency.

“…The recovery rate of hydrometallurgy is far from that of pyrometallurgy. In the acid leaching of electrode materials, inorganic acids are mostly used, usually including hydrochloric acid (HCl) (Li et al, 2009;Guo et al, 2016;Barik et al, 2017), sulfuric acid (H 2 SO 4 ) (Dun-Fang et al, 2009;Meshram et al, 2015Meshram et al, , 2016, nitric acid (HNO 3 ) (Li et al, 2011;Mossini et al, 2015), and phosphoric acid (H 3 PO 4 ) (Pinna et al, 2016;Chen et al, 2017), while the organic acids studied include citric acid (Li et al, 2010;Gao et al, 2019;Yu et al, 2019), oxalic acid (Zeng et al, 2015), and tartaric acid (Chen et al, 2019). Lee and Rhee (2003) used HCl to recycle LiCoO 2 and revealed the principle of acid leaching:…”

With the development of electric vehicles involving lithium ion batteries as energy storage devices, the demand for lithium ion batteries in the whole industry is increasing, which is bound to lead to a large number of lithium ion batteries in the problem of waste, recycling and reuse. If not handled properly, it will certainly have a negative impact on the environment and resources. Current commercial lithium ion batteries mainly contain transition metal oxides or phosphates, aluminum, copper, graphite, organic electrolytes containing harmful lithium salts, and other chemicals. Therefore, the recycling and reuse of spent lithium ion batteries has been paid more and more attention by many researchers. However, due to the high energy density, high safety and low price of lithium ion batteries have great differences and diversity, the recycling of waste lithium ion batteries has great difficulties. This paper reviews the latest development of the recovery technology of waste lithium ion batteries, including the development of recovery process and products. In addition, the challenges and future economic and application prospects are described.

“…In this case, time history curves composed of initial signals and pile defects or reflections produced at the pile bottoms can be received by the sensors (accelerometer or speedometer) installed at the pile top; the collected waveforms with pile body quality information can also be processed and analyzed via low strain pile dynamic tester; and the pile integrity shall be determined in conjunction with relevant geological data and construction records. The time-domain signals received at the pile top also include the superposition information caused by the increase or decrease (wave impedance decrease) of the soil resistance at the pile side (Ding et al, 2009;Ding and Tan, 2011). Therefore, the pile defect position can be estimated according to that of abnormal reflection signals in time-domain curves; and likewise the defect nature of broken pile can be judged by the phase change or frequency analysis of reflected signals.…”

Reflection wave method is a common approach to detect the foundation pile. However, if it is applied to the integrity test of pre-stressed pipe pile, the test results may vary with the pile-soil conditions. To evaluate the reliability on the application, this paper designs model piles with different degrees of defects, and tests the integrity of these piles at different stages. Through the analysis of the test curves, a large discrepancy was found between the pre-and post-sinking defects of the pre-stressed pile piles, indicating that the pile-soil conditions have a major impact over the defect causes and the limitations of the reflected wave method. RÉSUMÉ. La mé thode par ondes de ré flexion est une approche courante pour dé tecter le pieu de fondation. Toutefois, s'il est appliqué au test d'intégrité d'un pieu de tuyau précontraint, les ré sultats de ce test peuvent varier en fonction des conditions de pieu-sol. Afin d'évaluer la fiabilité de l'application, des pieux modé lisé s avec diffé rents degré s de dé fauts ont é té conç us dans cet article et leur inté grité à diffé rentes é tapes a é té testé e. A travers les analyses des courbes de ce test, un é cart important a é té trouvé entre les dé fauts avant et aprè s l'enfoncement des pieux de tuyau contraint, ce qui indique que les conditions de pieu-sol ont un impact majeur sur les causes des dé fauts et les limites de la mé thode des ondes ré flé chies.
