TL;DR: This paper first analyzes He-Wang's scheme, then proposes a new secure multi-server authentication protocol using biometric-based smart card and ECC with more security functionalities and shows that the proposed scheme provides secure authentication.

TL;DR: In this article, an economic order quantity (EOQoQ) inventory model for deteriorating goods is developed with a linear, positive trend in demand allowing inventory shortages and backlogging.

TL;DR: In this article, the inventory replenishment policy over a fixed planning period for a deteriorating item having a deterministic demand pattern with a linear trend and shortages is considered, and the number of reorders, the interval between two successive reorders and the shortage intervals over a finite time-horizon are all determined in an optimal manner so as to keep the average system cost to a minimum.

TL;DR: In this article, a deterministic inventory model is developed by assuming that the demand rate is stock-dependent and the items deteriorate at a constant rate, and the expression for the average net profit π over one production run is derived and its optimization with respect to the decision variables Q (initial stock) and T (duration of a production cycle) is carried out.

TL;DR: In this paper, an inventory model with an inventory-level-dependent demand rate followed by a constant demand rate for items deteriorating at a constant rate was discussed, where the terminal condition of zero inventory at the end of the scheduling period has been relaxed.
