use the statistical sampling plans in specifications monitoring and control industrial products quality in the light of the relationship between the producer and the consumer (applied case on Jood Factory for assembly electrical tools)


Abstract in English

This research deals with the study and analysis the issue of planning and designing statistical sampling plan in specifications and how to use in monitoring and control industrial products quality in the light of the relationship between the producer and the consumer by examining certain quantities of production based on criteria pre defined in order to judgement on the batch viability to reach an acceptable quality level or not. The acceptance preview concept involves on examination of materials and parts of the external source, product examination in its different parts and final examination for the product by one customer or more, by using American system (MIL-STD-105E) and tables of (Dodge and Roming) which related with statistical sampling plans. This research shows theoretical and practical how to design statistical sampling plans to adjust the industrial products quality and its application in products quality control of Jood company for assembling electrical tools using statistical program (SPSS). The study concludes to results confirm that the company doesn't have an application of statistical techniques in quality control and limited to measuring the output quality characteristics in the laboratory without a clear scientific method in examine batches such as designing statistical sampling plan. Jood company has certificates of Syrian and European standards of quality control so it had to be a recommendation for the company in application the scientific statistical sampling techniques in all production stages and training the staff on its application using specialists in the field of quality with plans showing the place and the time of doing sampling and determine sampling points in different production stages in order to promote the company with its products and provide products almost free of defects which qualifies the company to competition in foreign markets, not local.
