Six Big Losses

Six Big Losses
- التحسين المستمر, التصنيع اللين, الصيانة, الفعالية الكلية للمعدات (OEE), تقنيات حل المشكلات, تحسين العمليات, الإنتاجية, تحليل الأسباب الجذرية, سداسية سيجما
الهدف:
كيفية استخدامه:
- A key concept in Total Productive Maintenance (TPM), these are: Breakdowns, Setup and Adjustment Losses, Small Stops (Idling and Minor Stoppages), Reduced Speed, Startup Rejects (Defects in Process), and Production Rejects (Rework and Scrap).
الإيجابيات
- Provides a structured way to identify and prioritize OEE (Overall Equipment Effectiveness) improvements; Helps focus efforts on critical areas of equipment-related waste; Encourages a systematic approach to problem-solving.
السلبيات
- Primarily focused on equipment-related losses, may not cover all sources of inefficiency in a broader business context; Requires accurate data collection to quantify losses effectively.
الفئات:
- لين سيجما, التصنيع, حل المشكلات, الجودة
الأفضل لـ
- Systematically identifying and tackling the primary causes of equipment-based productivity loss to improve Overall Equipment Effectiveness (OEE).
The Six Big Losses methodology serves various industries, particularly manufacturing, automotive, aerospace, and food processing, where maximizing equipment efficiency is essential. Applications include assembly lines, CNC machining, and packaging operations, aiding engineers and operations managers in identifying bottlenecks that hamper production rates. This methodology can be initiated during the planning phase of a new production line or as part of ongoing maintenance programs. Cross-functional teams involving maintenance technicians, production operators, and quality control personnel can collaboratively assess and document each loss type, leading to targeted improvement initiatives. For instance, regular analysis of breakdown trends can guide preventive maintenance schedules, while monitoring small stops can lead to adjustments in machinery or training for operators. Implementing the Six Big Losses approach aligns with Lean Manufacturing principles, as it systematically categorizes and prioritizes instances of waste, transforming data into actionable strategies. Encouraging a culture of continuous improvement, this methodology can pave the way for enhanced team collaboration and the adoption of best practices in equipment management, ultimately driving improvements in product quality, operational uptime, and profitability.
