In this paper, a two warehouse inventory model with stock and time dependent demand and permissible delay in payment for decaying items has been developed. In most of the inventory models, researcher assumed only a single warehouse with fixed capacity, but for a large stock it is not realistic we have assumed a two warehouse with abundant capacity. Deterioration rates of items in the two warehouses may be different. We assume that the inventory costs (including holding cost and deterioration cost) in RW are higher than those in OW. We show that the optimal replenishment policy not only exists but also is unique. Numerical examples are also illustrated.
 

Prey-predator SIR model with generalized death rate of prey species has been analyzed. Local and global stability has been discussed. Model analyzed by Han and Ma⁷ follows as a corollary.
 

The present paper is devoted to common fixed point theorem of mapping in complete metric space. Also in the present paper we have given some new results which are the generalization of the results of Banach¹, Fisher², Dhage³, Kannan⁴, and Istrateseu⁵.

In this paper, we establish fixed point theorems in Banach space using S-iterative for nonexpansive mapping in Banach space which satisfies Opial's condition and S-iterates extend of Pathak⁹ and also the S-iterative scheme {x_n} is defined by (2.3)
