الجودة والتفتيش
Mar 21, 2018

يتم وصف أربع فئات أساسية من تكاليف الجودة في ما يلي:

1 ، الوقاية ---- التكاليف المتكبدة في تخطيط وتنفيذ والحفاظ على نظام الجودة التي من شأنها ضمان المطابقة لمتطلبات الجودة على المستويات الاقتصادية. ومن أمثلة تكاليف الوقاية التدريب على استخدام مراقبة العمليات الإحصائية.

2 ، تقييم --- التكاليف المتكبدة في تحديد درجة المطابقة لمتطلبات الجودة. مثال على تقييم التكلفة هو التفتيش.

3 ، الفشل الداخلي --- التكاليف الناشئة عندما تفشل المنتجات والمكونات والمواد في تلبية متطلبات الجودة قبل نقل الملكية إلى العميل. مثال على تكلفة الفشل الداخلي هو الخردة.

4 ، فشل خارجي --- التكاليف المتكبدة عندما تفشل المنتجات في تلبية متطلبات الجودة بعد نقل الملكية إلى الزبون. مثال على تكاليف الفشل الخارجي هو مطالبات الضمان.

على الرغم من أن مستوى مراقبة الجودة يتحدد في جزء كبير منه من خلال نظرية الاحتمالات والحسابات الإحصائية ، من المهم جدًا أن تكون عمليات جمع البيانات التي تعتمد عليها هذه الإجراءات ملائمة ودقيقة. إن أفضل إجراء إحصائي لا قيمة له إذا تم تغذية البيانات المعيبة ، ومثل عمليات المعالجة ، فإن جمع بيانات التفتيش هو في حد ذاته عملية ذات حدود عملية للدقة ، الدقة ، الدقة والتكرار.

يمكن تحديد جميع عمليات التفتيش و / أو القياس من حيث دقتها وتكرارها ، مثلما يتم تقييم عملية التصنيع للتأكد من دقتها وإمكانية تكرارها. يمكن إجراء تجارب مراقبة ، ويمكن إجراء مقاييس إحصائية للنتائج لتحديد أداء طريقة الفحص بالنسبة للأجزاء المراد فحصها. يمكن الحكم على ملاءمة طريقة أو طريقة أخرى على أساس الانحرافات المعيارية ومستويات الثقة التي تنطبق على كل نهج كما هو مستخدم في حالة تفتيش معينة.
