碩士 === 中原大學 === 應用數學研究所 === 98 === In this highly global competition ,how to reduce enterprise’s cost and raise the value of goods,has become the key consideration to improve an enterprise’s competitiveness in the market. Here we used the present value method to research the target of reducing the cost of goods.In order to minimize cost,a set of optimized inventory model including inferior goods is designed and defined by the way of agreement and contract.Using the method of mathematical analysis, we found the optimal order time and the optimal inventory cost.The research not only conformed to the optimal economic cost but also raised the value of the enterprise. Compared this research with the optimal inventory modelling including inferior goods on one cycle using average cost.In this paper,the optimal order time of the optimal inventory modelling including inferior goods by the present value was shorter than the other.But the optimal inventory cost of the optimal inventory modelling including inferior goods by the present value was less than the other.Therefore the enterprise could use the optimal inventory modelling including inferior goods by the present value.Though the optimal order time was shorter,the optimal inventory cost was lower.The research not only improved an enterprise's competitiveness but also became the key consideration to determine the decision of the enterprise.
