However, many researchers have observed that the presence of more quantities of the same product tends to attract more customers. This suggests that the demand rate should depend on the stock level. This paper presents a single-vendor-single-buyer production-shipment model with the stock dependent demand rate, based on the demand rate linearly depending upon the stock level at any instant of time.展开更多

Unlike the conventional method by using differential calculus to determine replenishment lot size and optimal number of shipments for such an integrated system, this paper proposes a straightforward algebraic approach to replace the use of calculus on the total cost function for solving the optimal production- shipment policies. A simpler form for computing long-run average cost for such a vendor- buyer integrated EPQ problem is also provided.展开更多

In November 2014, the overall shipments of mobile phones reached 44.543 million units in China. Among which 2G mobile phone shipments was of 5.742 million, 3G mobile phone was of 7.2 million and 31.601 million for 4G ones. 4G mobile phone shipments continued to increase rapidly, which was more than 4 times of 3G mobile phone shipments.展开更多

The impressive record is attributed to the continuous robustness and expansion of the international GSM market, which the company took advantage of by launching several GSM product marketing campaigns in Asia Pacific.展开更多
