Abstract
A method and system for generating a production sequence for the resources of a manufacturing plant. This method comprises the steps of identifying the total amount of each product that the plant has to produce in one period of time, identifying the operation route and productivity for each product on each available resource, and identifying setup constraints. The method includes the further steps of identifying delivery dates already committed, and identifying the minimum and maximum stock levels for each resource. The identified factors are then used to generate a production sequence for each resource of the plant with a granularity of a defined time period.
Claims18
A method for generating a production sequence for the resources of a manufacturing plant, comprising the steps:
- (A) identifying the total amount of each product that the plant has to produce in one period of time including both already received orders and expected future orders for said one period of time;
- (B) identifying the operation route and productivity for each product on each available resource;
- (C) identifying setup constraints;
- (D) identifying delivery dates already committed;
- (E) identifying the minimum and maximum stock limits for each resource;
- (F) using the factors identified in steps (a) through (e) to generate a production sequence for each resource of the plant with a granularity of a defined time period.
A system for generating a production sequence for the resources of a manufacturing plant, comprising:
- (A) means for identifying the total amount of each product that the plant has to produce in one period of time including both already received orders and expected future orders for said one period of time;
- (B) means for identifying the operation route and productivity for each product on each available resource;
- (C) means for identifying setup constraints;
- (D) means for identifying delivery dates already committed;
- (E) means for identifying the minimum and maximum stock limits for each resource;
- (F) means for using the factors identified elements (a) through (e) to generate a production sequence for each resource of the plant with a granularity of a defined time period.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for generating a production sequence for the resources of a manufacturing plant, the method comprising the steps:
- (A) identifying the total amount of each product that the plant has to produce in one period of time including both already received orders and expected future orders for said one period of time;
- (B) identifying the operation route and productivity for each product on each available resource;
- (C) identifying setup constraints;
- (D) identifying delivery dates already committed;
- (E) identifying the minimum and maximum stock limits for each resource;
- and
- (F) using the factors identified in steps (a) through (e) to generate a production sequence for each resource of the plant with a granularity of a defined time period.
