Optimal production planning for workshops with demand constraints

YAN Hong sen,ZHANG Xiao dong,DONG Hao (Research Institute of Automation, Southeast University, Nanjing 210096,China)  
The paper explores the problem of the optimal production planning in flexible automa ted workshops(FAWs) under the condition of demands being just satisfied. A nonlinear programming model of production planning with demand constraints is built up and then transformed into a linear programming model by adding constraints. Because the scale of the model for a general workshop is too large to be solved in simplex method on a microcomputer within accep table time, a Karmarkars algorithm and an interaction/prediction algorithm are used to solve the model, on the basis of which the corresponding programs have been written.Through production planning examples, the Karmarkars algorithm, interaction/prediction algorithm and linear programming method in Matlab are compared, thus showing that the proposed approaches are very suitable for decomposing optimally medium term plans(assigned to an FAW by ERP/MRPⅡ) into short term plans (to be executed by FMSs in the FAW).
