Research on quality evaluation of simple fresh-keeping storage equipment:Taking Beijing as an example
In order to realize the popularization and application of simple preservation and storage equipment,it is necessary to determine the quality evaluation method of simple preservation and storage equipment.By analyzing and studying the quality investigation and evaluation method of simple preservation and storage equipment and carrying out practical application,the safety,reliability,adaptability and after-sales service status of simple preservation and storage equipment are investigated and evaluated,and the overall quality level of in-use preservation and storage equipment is mastered.Based on the analysis and study of the composition,parameters and functional principle of simple preservation and storage equipment,the possible conditions and faults in the actual operation and use of the equipment,the quality requirements of the user's use of the equipment and the service experience,the quality evaluation indicators of the equipment are set up,and each indicator is assigned a different weight coefficient.Among them,there are 5 first-level indicators,which are safety,applicability,reliability,material use load degree,after-sales service,and there are 25 secondary indicators.In the first level index,safety 25 points,applicability 20 points,reliability 20 points,material usage load 20 points,after-sales service 15 points.The results show that the weighted score of all samples of simple fresh-keeping storage equipment is 83.10.The production performance of the products of the three companies is good,and the product design standards are reached.
