It’s a common method for companies to mitigate the impact of supply disruptions by sharing the redundant capacity from other firms through transshipment. In this paper, from the perspective of the retailer, we study that when the supplier's supply fails to meet the retailer's order demand due to an emergency, the disrupted retailer requests transshipment at the transshipment price set by the others to satisfy customers demand during the disruption. In each period during the disruption, we propose the optimal dynamic transshipment decision policies for two scenarios of customer demand. Based on the Newsvendor problem, we find that the relationship among transshipment price, stock-out cost and salvage value impact retailer's decision on the transshipment quantity.

According to ohmic heating principle, inductively coupled thermal plasma torch relies on electromagnetic field generated by RF current of external toroidal coil to penetrate gas in torch so that plasma can be motivated and maintained, where the maximum temperature can reach from10000 to 11000K. Based on previous simulation models, electromagnetic field calculation domain is expanded to air region outside plasma discharge region in this paper, and COMSOL software is used for multi-physics coupling calculations so that magnetic vector potential distribution, temperature distribution, and velocity distribution of plasma are obtained, whose physical mechanism is analyzed as well.

The dual-channel supply chain model of fresh product under random market demand considering the retailer’s fairness concern is constructed in this paper, in which the supply chain members share the fresh keeping cost. Comparing the models for retailer's fairness neutral and fairness concern, the effects of the sharing ratio of fresh keeping cost, fairness concern coefficient and random disturbance factor on the decision-making of supply chain members are discussed. The analysis shows that whether the retailer is fairness concern or not, the effects of random disturbance factor on the retailer's online price, offline price and the level of fresh effort are proportional. And the retailer's fairness concern coefficient and sharing ratio of fresh keeping cost have different influences on the decision-making of supply chain members.

With continuous increase of society’s demand for energy, higher requirements have been placed on the supply of electricity. While field of power grids continues to introduce more new energy sources, it also requires power grid to provide stable and sustainable energy supply chain. According to equipment response and fault protection caused by grid faults, protection sequence coordination methods for multiple types of fault current-limiting equipment including fault current limiters, DC circuit breakers, hybrid MMCs and converters are proposed in this paper. In addition, for DC circuit breaker to isolate the fault, there is rejection to act, and fault current limiter and DC circuit breaker are required to cooperate after DC line failure in upper-layer ring network system so that half-bridge converters can block faults on both sides of converter during DC line faults. What’s more, reliability of DC circuit breaker is determined by detecting the rate of change in fault current, and different fault current limiting devices need to cooperate with each other according to different fault areas in composite DC grid. Reasonable timing coordination strategy can effectively isolate the effect of faults. Finally, it is verified by simulation that upper-layer ring network system needs to trigger the start of fault current limiter, Meanwhile, backup line DC circuit breaker in faulty line and adjacent line as well as exit side of converter station needs to be triggered too. Moreover, lower multi-terminal system is set to require lockout signal for converter, and hybrid MMC converter station needs to be put in lock-free ride-through control mode, which realizes the rationality of research content in this paper.

The soft-sensor model for identifying the source of mine water inrush and its performance are studied experimentally. In this novel framework, principal component analysis (PCA) has been used to decompose the original water quality historical data into several sub principal component data which can effectively extract the characteristics of multivariate time series. After that, cycle reservoir with hierarchical jumps (CRHJ) model is established by training and verifying the principal component data. Through the simulation and verification of the historical water inrush data of two measured mines, the experimental results show that the PCA-CRHJ model shows the best performance compared with echo state network (ESN) and cycle reservoir with jumps (CRJ) models generally. The hybrid model, with accurate and stable results, is highly effective for mine water inrush source discrimination and can flexibly be applied in other mine regions.

According to the roadway floor burst in Yuejin mine, numerical simulation was adopt to analyze the theory principle of floor burst, and there were two situations. One was to weaken the strength of the coal floor directly, the other was to weaken the strength of both sides of the coal body, so as to relieve the horizontal stress of the floor. The results showed that the distance of the peak stress displayed stepped change with the increasing strength weakening of the coal body. The distance of the peak stress was 8.75 meters without any measures, the distance was 6.25 meters when decreased 1 %~ 20%, the distance was 6.25 meters to 8.75 meters when decreased 20%~30%, and the distance stayed on 8.75 meters when it was reduced by more than 40%, at this time peak stress had already transferred to the floor strata and the rock burst hazard almost disappeared. Finally the reasonable pressure relief scheme of floor was determined, and this paper provided theoretical guidance for controlling the floor burst of Yuejin mine.
