Research On The Evaluation Of Shandong Aluminium Company Based On The IHSA_LSSVM Performance

In the "twelve-five" plan, there is putting forwarded to reform, improve manufacturing industry. The specific strategy is to optimize structure, improve the quality of varieties, strengthen the industrial supporting ability, eliminate the backward production capacity, the develop the manufacturing industry of advanced equipment, adjust and optimize raw material industry, transform and promote the industry of consumer goods, make the industry to be stronger. In the background of the "twelve-five" plan, how to carry out the transformation and ascending on manufacturing industry in Liaoning province is a great question of being.Shandong Aluminum Company in-depth study:(1) Shandong Aluminum Company supply chain performance target selection. Through the actual situation of Shandong Aluminum Company research and collected data, combined with the idea of the Balanced Scorecard, a clear assessment of the impact of supply chain performance factors. (2) build Shandong Aluminum Company of supply chain performance evaluation index system. From a financial perspective, business process perspective, customer perspective, learning and innovation to build four aspects and indicators of various factors to be quantized. (3) on harmony search algorithm has been improved. On harmony search algorithm (HSA) to study the principle, through the use of dynamically adjusting harmonies memory retention probability, the probability of the base and the base tone pitch adjustment step size and other parameters, an improved harmony search algorithm. (4) It proposes based on improved harmony search algorithm (IHSA) and the least square support vector machine (LSSVM) combined evaluation algorithm. With the existing literature by BP neural network algorithm and LSSVM peer evaluation to quantify, it is shown IHSA_LSSVM has a smaller prediction error and higher prediction accuracy (5) Shandong Aluminum Company supply chain performance evaluation. Combined data were collected in 2006,2007,2008,2009,2010,2011, Shandong Aluminum Company established before the information and come to a good evaluation system requires the use of the raw data, the raw data were normalized after treatment, allowing the algorithm to the second half of the first five years of supply chain performance information for learning, for the second half of 2011 on supply chain performance awakened to develop improved prediction.
