the rapid development of information technology, customers’ consumption pattern
in hotel industry has dramatically changed, and many people book rooms through
some professional online platforms. Hotel managers need to redesign their sale
channel structures by incorporating online platforms, in order to increase
profit. This paper focuses on a revenue maximization problem for a hotel which
cooperates with an online platform. Two cooperating forms are investigated and
compared. Specifically, one intuitive form is named complete sharing, in which all the hotel rooms are shared with the
online platform for booking. The other form is named setting online-exclusive-rooms (OERs), in which the hotel set a
fixed quantity of rooms for exclusively booking from the online platform. By
building a loss queueing model, this paper finds some properties of the optimal
quantity of OERs in the latter form. Factors affecting the selection and how
they affect the selection are also investigated.
In this article, we studied the bearings made by one company in Shanghai. Through statistical process controlling the quality characteristic of bearings’ diameters and multi-vary analysis is applied to find the key variation factors which have an influence on the quality characteristic of the bearings, the quality level of the bearings of this company is improved.
Based on the accurate identification of chemical
structures as electric elements, we described charge transport mechanism in a
DNA molecule by a stepwiseLCoscillatory circuitry, in which every base pair is a capacitor, every phosphate
bridge is an inductor, and every deoxyribose is a charge router. The circuit
model agrees with established experimental evidence that has supported
super-exchange and hopping mechanisms so far. This alternative charge transport
mechanism through both strands of DNA matches the fidelity and reliability of
its chemical structure.
