Study On Material Requirement Planning Optimization Based On Six Sigma

The ultimate goal of Material Requirements Planning is to optimize the productionand procurement activities. Regardless of material shortage or surplus, it will bring a lot ofnegative effects into normal production and business operation of enterprise. Therefore,the enterprise has to find a scientific, effective and practical method to manage theoperation of the materials demand planning deficiencies.This paper is trying to apply six sigma management methods into materialrequirement planning process. Looking forward to solve daily operation problems of thematerial requirement planning via Six Sigma process improvement model. This paper alsoapplied Six Sigma management theory into material requirements planning process to findout the optimization of feasibility. To the authors in W company to do up to six sigmaproject, in practice level to verified what it really improved via six sigma processimprovement model DMAIC method (Define, Measure, Analysis, Improve, Control).Getting start with definition phase to defining the real problems, in the measurement phaseby drawing characteristic diagram to identify all the factors which effects of materialrequirement planning output accuracy, then use of causal matrix to screen out theinfluential factors into the analysis phase, using failure mode and effect analysis toolFMEA for the analysis of these key input options, in the fourth stage the implementationof key input variables and process improvements, until the final control stage onimprovement and optimization of the process of exerting control after on the improvementof the content and the implementation of standardized, so as to enhance the W companyMRP output accuracy as of objective.
