OEE combines availability, performance and quality. It helps teams see whether output is lost through downtime, slow running or defects.<\/p>\n\n\n<p class=\"wp-block-paragraph\">Use OEE with the loss events behind the number. A percentage alone does not explain a production problem.<\/p>\n\n\n<h2 class=\"wp-block-heading\">How is OEE calculated?<\/h2>\n\n\n<p class=\"wp-block-paragraph\"><strong>OEE = Availability \u00d7 Performance \u00d7 Quality<\/strong><\/p>\n\n\n<ul class=\"wp-block-list\"><li><strong>Verf\u00fcgbarkeit<\/strong> compares planned production time with the time the equipment actually runs. Breakdowns, setups, changeovers and waiting reduce the result.<\/li><li><strong>Leistung<\/strong> compares the actual rate with the ideal cycle time or target rate. Slow cycles and short interruptions reduce performance.<\/li><li><strong>Qualit\u00e4t<\/strong> measures the share of output that meets requirements. Scrap and rework reduce quality.<\/li><\/ul>\n\n\n<p class=\"wp-block-paragraph\">Because the factors are multiplied, a weak result in one area can pull down the total OEE even when the other factors look healthy.<\/p>\n\n\n<h2 class=\"wp-block-heading\">What losses does OEE reveal?<\/h2>\n\n\n<ul class=\"wp-block-list\"><li><strong>Availability losses:<\/strong> failures, changeovers, waiting and other stops.<\/li><li><strong>Performance losses:<\/strong> reduced speed, minor stops and running below the ideal rate.<\/li><li><strong>Quality losses:<\/strong> startup rejects, defects, scrap and rework.<\/li><\/ul>\n\n\n<p class=\"wp-block-paragraph\">This breakdown helps a team move from \u201cOEE fell\u201d to a practical question such as \u201cwhich stop reason, speed loss or defect contributed most?\u201d<\/p>\n\n\n<h2 class=\"wp-block-heading\">OEE example<\/h2>\n\n\n<p class=\"wp-block-paragraph\">A line has 480 minutes of planned time. It runs for 420 minutes, reaches 90% of its ideal rate and produces 95% good units. Its OEE is 87.5% \u00d7 90% \u00d7 95%, or about 74.8%.<\/p>\n\n\n<p class=\"wp-block-paragraph\">OEE therefore differs from uptime. Uptime describes whether equipment was running. OEE also measures the rate and quality of the output.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Benefits and limitations of OEE<\/h2>\n\n\n<ul class=\"wp-block-list\"><li>creates a shared language for production losses;<\/li><li>helps teams prioritise improvement work with measured evidence;<\/li><li>supports comparisons when sites use the same definitions; and<\/li><li>shows whether an action affected downtime, speed or quality.<\/li><\/ul>\n\n\n<p class=\"wp-block-paragraph\">OEE can mislead when teams define planned time, ideal cycle times, stop reasons or quality inconsistently. It should not become a target that encourages people to hide stops or lower the ideal rate. Use it with safety, delivery, cost and maintenance measures.<\/p>\n\n\n<h2 class=\"wp-block-heading\">When should a manufacturer use OEE?<\/h2>\n\n\n<p class=\"wp-block-paragraph\">OEE is a useful starting point when a manufacturer needs a consistent view of line performance, wants to identify hidden losses or is prioritising continuous improvement. Agree on the calculation rules before comparing lines or sites.<\/p>\n\n\n<p class=\"wp-block-paragraph\">For a commercial overview of automated OEE and loss analysis, see <a href=\"https:\/\/accevo.com\/de\/produkte\/oee-leistungsuberwachung\/\">Accevo OEE and micro-stops intelligence software<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>Learn what Overall Equipment Effectiveness (OEE) means, how availability, performance and quality combine in the OEE formula, and how manufacturers use the metric.<\/p>","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"wpai_generated_summary":"","footnotes":""},"categories":[32],"tags":[],"class_list":["post-38241","post","type-post","status-publish","format-standard","hentry","category-glossary"],"_links":{"self":[{"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/posts\/38241","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/comments?post=38241"}],"version-history":[{"count":0,"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/posts\/38241\/revisions"}],"wp:attachment":[{"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/media?parent=38241"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/categories?post=38241"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/accevo.com\/de\/wp-json\/wp\/v2\/tags?post=38241"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
