Dual-warehouse management system and method for calculating the minimum joint cost of a supply chain
First Claim
1. A dual-warehouse management system for a supply chain, wherein the supply chain comprises a manufacturer and a distributor, the manufacturer delivers a product lot of a deteriorating item to the distributor, and the distributor manages a primary distribution warehouse and a secondary distribution warehouse and stores the product lot in the primary distribution warehouse, and stores remained product lot in the secondary distribution warehouse when the primary distribution warehouse reaches a maximum capacity, and the dual-warehouse management system for a supply chain comprising:
- a storage device, storing a plurality of programs written based on a computer programming language; and
a central processing unit, executing the programs;
wherein the programs comprising;
a manufacturer function module, estimating a total cost of the manufacturer according to a manufacturing inventory level, a manufacturing deteriorating cost and a delivery times of the deteriorating item for the manufacturer;
a distributor function module, estimating a total cost of the distributor according to a respective distributing inventory level, a respective distributing deteriorating cost of the deteriorating item for the primary distribution warehouse and the secondary distribution warehouse, the delivering frequency, and shortage cost; and
a joint cost optimization module, calculating a minimum of a joint cost obtained by adding the manufacturer'"'"'s total cost and the distributor'"'"'s total cost, so as to obtain the product lot and the delivery times of the deteriorating item to be delivered from the manufacturer to the distributor in a planning time horizon,wherein the joint cost optimization module compares the joint costs with the delivery times of n, n+1 and n−
1, and when the joint cost with the delivery times of n is less than or equal to the joint cost with the delivery times of n+1, and meanwhile when the joint cost with the delivery times of n is also less than or equal to the joint cost with the delivery times of n−
1, the joint cost with the delivery times of n is determined to be the minimum.

Abstract
A dual-warehouse management system for a supply chain and a method for calculating a minimum of a joint cost thereof are provided. A manufacturer function module and a distributor function module are used to estimate a manufacturer'"'"'s total cost and a distributor'"'"'s total cost respectively. Afterwards, a joint cost optimization module is used to calculate a minimum joint cost. Accordingly, a product lot and a delivery time of a deteriorating item delivered from the manufacturer to the distributor are obtained in a planning horizon.

8. A method for calculating a minimum joint cost for a dual-warehouse management system of a supply chain, performed on a computer, wherein the supply chain comprises a manufacturer and a distributor, the manufacturer delivers a product lot of deteriorating items to the distributor, and the distributor manages a primary distribution warehouse and a secondary distribution warehouse and stores the product lot in the primary distribution warehouse, and stores remained product lot in the secondary distribution warehouse when the primary distribution warehouse reaches a maximum capacity, the method for calculating a minimum joint cost comprising:
-
providing the manufacturer'"'"'s information and the distributor'"'"'s information into a storage device of the computer, the manufacturer'"'"'s information comprising a manufacturing inventory level and a manufacturing deteriorating cost of the deteriorating item, and the distributor information comprising a respective distributing inventory level and a respective distributing deteriorating cost of the deteriorating item in the primary distribution warehouse and the secondary distribution warehouse; reading the manufacturer'"'"'s information and the distributor'"'"'s information from the storage device by a central processing unit of the computer for executing following steps, comprising; respectively estimating the manufacturer'"'"'s total cost and the distributor'"'"'s total cost according to the manufacturer'"'"'s information and the distributor'"'"'s information; estimating a minimum of a joint cost obtained by adding the manufacturer'"'"'s total cost and the distributor'"'"'s total cost for calculating an approximate solution of the product lot, so as to obtain the product lot and a delivery times of the deteriorating item to be delivered from the manufacturer to the distributor in a planning horizon; comparing the respective joint costs with the delivery times of n, n+1 and n−
1 based on the product lot, wherein n is a positive number and an initial value thereof is 1; andwhen the joint cost with the delivery times of n is greater than the joint cost with the delivery times of n+1, or when the joint cost with the delivery times of n is greater than the joint cost with the delivery times of n−
1, adding 1 to n and repeatedly calculating another approximate solution of the product lot until the joint cost with the delivery times of n is less than or equal to the joint cost with the delivery times of n+1, and meanwhile the joint cost with the delivery times of n is also less than or equal to the joint cost with the delivery times of n−
