| Abstract | This study considers lot sizing problems in multi-stage production-inventory systems subject to resource capacity constraints and the bill of material composed of assembly structure. This is a computationally complex problem and forms a part of the decision set with the MRP systems. It deals with the determination of a production plan for the end products and their components in order to meet the forecast demand in each period of planning horizon. The production plan aims at the minimisation of the sum of production, set up and holding costs. A mathematical model has been developed in terms of echelon stock. A rounding procedure has been proposed for a LP-based heuristic method. Computational results of the test problems have been reported. The solution quality was evaluated against the optimal value of the objective function given by the software LINGO. After validation, this heuristic has been applied to yield the production plan for a practical case of Dongda Bicycle Company, Vietnam. |
