Firms often utilize and coordinate dynamic adjustment of price, non-price promotions such as advertisement and recruitment of excellent salespeople and proper inventory replenishment policies to satisfy customer demands and achieve maximal profit. This paper provides an analytical model for...

In this paper, a new trust region method for the system of nonlinear equations is presented in which the determining of the trust region radius incorporates the information of its natural residual. The global convergence is obtained under mild conditions. Unlike traditional trust region method,...

In this paper, a new trust region method is presented for general constrained optimization problem. In this algorithm, the trial step is obtained by solving two quadratic programming problems with bound constraints. The algorithm is implementable easily. Then we prove that the method is globally...

Firms often utilize promotion (such as coupons, advertisements, recruitment of excellent salespeople, and leafleting etc.) and dynamic adjustment of price to manage customers as well as proper production/inventory plan to satisfy the customers to get maximal profit in a firm. The decision on...

This paper addresses a supplier selection and purchase problem under stochastic demand. In particular, a buyer firm (manufacturer or retailer) wants to procure a product from a group of potential suppliers, which may quote different prices and have restriction on minimum and maximum order sizes,...

This paper employs quarterly observations on US dollar prices of the pound, Deutschmark, Swiss franc, and yen from 1973,2 to 1994,4 to sort out three broad issues raised by recent work showing that economic fundamentals have predictive power for exchange rates at long horizons. Three alternative...

This paper attempts to investigate the determinants of the capital structure of a sample of 972 listed companies on the Shanghai Stock Exchange and Shenzhen Stock Exchange in China in 2003. Various theories, namely, the trade-off, pecking order and agency theories, are deployed to explain and...
