<p><P>PROBLEM TO BE SOLVED: To provide a method of planning optimum quantities of plants of respective factories when an enterprise having the plurality of factories supply products of different grades to a plurality of consumption areas. <P>SOLUTION: The total production quantity is represented as (P<SB>1-1</SB>+P<SB>2-1</SB>+P<SB>1-2</SB>+P<SB>1-3</SB>+P<SB>1-4</SB>+P<SB>2-4</SB>), where P<SB>1-1</SB>is the optimum production quantity of a product grade 1 of a plant 1, P<SB>2-1</SB>the optimum production quantity of a grade 2, P<SB>1-2</SB>the optimum production quantity of the grade 1 of a plant 2, P<SB>1-3</SB>the optimum production quantity of the grade 1 of a plant 3, P<SB>1-4</SB>the optimum production quantity of the grade 1 of a plant 4, and P<SB>2-4</SB>the optimum production quantity of the grade 2. Here, raw-material cost+utility cost-subproduct selling amount+transportation cost are generated respectively and then respective optimum production quantities are so calculated that the total production cost obtained by totaling them becomes minimum. <P>COPYRIGHT: (C)2004,JPO</p> |
