With the development of behavioral operational management, human behavior such as altruism, fairness and trust has received considerable attention. This paper studies the effect of altruism on retailer’s and manufacturer’s pricing strategy in two classic dual-channel supply chains by presenting Stackelberg game models. The analysis shows that the player’s altruism preference strongly affects their pricing strategies. The more altruistic one player is, the more profits the other player obtains. Moreover, the effect of manufacturer’s altruistic preference is larger than that of retailer’s. In addition, online price is always lower than offline price in dual-channel supply chain, which still holds true considering altruism. The results also reveal that the product web-fit has significant effect on the player’s optimal pricing strategies. The more compatible with online market the product is, the lower the retail price is set, and the more profit the manufacturer obtains whereas the less the retailer gets.
This paper uses mathematical statistics method and analyzes the main scoring techniques: the serve technique, the jump smash technique, the net lob technique, the pushing backcourt ball technique and the smash technique by analyzing the data of the 29th Olympic Games by He Hanbin/Yu Yang (China) and Nova/Nasir (Indonesia). The analysis shows that: in the badminton mixed doubles match, since both sides are partners for many years, in order to win the game you must have good badminton technique; particularly the error rate of the net lob technique and the pushing backcourt ball technique is high, which needs further practice. The study plays a certain role in promoting the development of badminton technique and the popularization of badminton sports.
selective surfaces (FSSs) have been successfully used in constructing microwave
absorbers which demonstrate the ability of modifying and improving its absorbing
performances. In this paper, microwave absorber based on ferromagnetic nano-films
has been proposed and investigated with a structure similar to that of the Salisbury
screen except that the resistive sheet is replaced by FSS of square patch array
of the nano-film. We have explored the FSS absorber from three aspects: equivalent
circuit model, electromagnetic full-wave simulation and the actual sample measurement.
By carefully tuning the patch size, the thickness of the dielectric spacer and the
specification of the ferromagnetic nano-film, we obtain the optimized performance
of broadband microwave absorbing. Due to the light weight of the nano-films, the
proposed absorbers can achieve an ultra-low surface density less than 0.25 kg/m2.
