Abstract:
تناولت هذه الدراسة اسلوبين جديدين للعمل وهما نظام تكنلوجيا المجاميع ونظم دعم القرار. وبينت اثر استخدام كل واحد منهما على الشركات بصورة عامة وعلى الشركة عينة الدراسة مصنع محرك مبردة الهواء بشكل خاص.وتهدف هذه الدراسة بالدرجة الاساس الى بيان اثر استعمال نظ | This study handles two new techniques that are : Group Technology System and Decision Support Systems and states the effect of using each one on the companies in general and the company, the sample of this study, in special. The study is aiming basically at encouraging the owners of industrial companies to use group technology system instead of the traditional production systems to improve the quality that meets the customers needs and wishes, to reach the productive flexibility related usually to functional manufacturing systems, and to elevate the productive efficiency related to the large production systems. Also groups cells are formed with the support of decision supported systems to contribute in eliminating time, effort, and cost required in making the important manufacturing decisions ; by using the computerized systems through keeping and recovering information and data that couldn't be obtained manually. The internal order for the factory is stated in the research with applying two methods to form manufacture cells which are Rank Order Clustering (ROC) and Occupancy Value (OV) for the factory of air - cool motor, the sample of the research, in state company for Electronic Industries, and by using these methods machines groups and parts families are formed. In addition to the use of parts assignment method for the machine as away to improve grouping after inserting the data in computer and handling them according to Visual Basic Language and Excel and Access Programs. The two methods are evaluated according to a number of form efficiency measures of groups of cells, they are compared and the method of the best form is selected depending on these measures , and the rules of scheduling technological groups system are used for the two methods, and we have evaluated the results in term of evaluation standards of the rules of cells scheduling depending on factory performance.The study has reached into a number of conclusions about the factory that are : the decision supported systems aren't used and their features are not exploited for enhancing the product, and the management usually hesitates of taking groups technology system. The research has come into that the best method for making manufacturing cells in the factory, the research sample is Rank Order Clustering method depending on the results reached according to the measures of grouping efficiency, and the procedure done of scheduling the cells by three rules of manufacturing cells scheduling and finally, a comparison is made between these rules by the use of evaluation standards of scheduling rules related to factory performance
