Az SPC bevezet\u00e9se a termel\u00e9sben minden, csak nem mag\u00e1t\u00f3l \u00e9rtet\u0151d\u0151...<\/p>\n\n\n\n

B\u00e1r az SPC m\u00e1r j\u00f3l ismert az iparban, hiszen az els\u0151 kontrollgrafikonokat m\u00e1r 1930-ban bevezett\u00e9k, kider\u00fclt, hogy 100 \u00e9vvel k\u00e9s\u0151bb m\u00e9g mindig nem tal\u00e1lt\u00e1k meg a var\u00e1zsformul\u00e1t az SPC helyes alkalmaz\u00e1s\u00e1ra. B\u00e1r a kontrollgrafikonok matematikai \u00e9s statisztikai fogalmakb\u00f3l erednek, az emberek azok, akik az SPC-t a mindennapokban \u00e9letre keltik, \u00e9s sajnos az emberek \u00e9s a matematika nem mindig f\u00e9rnek \u00f6ssze!<\/p>\n\n\n\n

B\u00e1r az SPC bevezet\u00e9s\u00e9re nincs var\u00e1zslatos recept, van n\u00e9h\u00e1ny hiba, amelyet el kell ker\u00fclnie, ha maximaliz\u00e1lni akarja a siker es\u00e9lyeit. \u00cdme az SPC bevezet\u00e9sekor elk\u00f6vetett 5 leggyakoribb hiba.<\/p>\n\n\n\n

1. Nem vonj\u00e1k be az \u00f6sszes alkalmazottat<\/strong><\/h3>\n\n\n\n

Az SPC-t gyakran a m\u00e9rn\u00f6k\u00f6k vagy statisztikusok sz\u00e1m\u00e1ra fenntartott tev\u00e9kenys\u00e9gnek tekintik, m\u00e9g akkor is, ha nem \u0151k azok, akik a g\u00e9pet a mindennapokban be\u00e1ll\u00edtj\u00e1k. A val\u00f3s\u00e1gban az SPC siker\u00e9hez mindenkit be kell vonni, k\u00fcl\u00f6n\u00f6sen a kezel\u0151ket. Ehhez ki kell k\u00e9pezni \u0151ket, \u00e9s meg kell ismertetni vel\u00fck az elt\u00e9r\u00e9s \u00e9s a korrekci\u00f3 fogalm\u00e1t. Egy\u00e1ltal\u00e1n nem sz\u00fcks\u00e9ges mindenkinek elmagyar\u00e1zni a k\u00e9pess\u00e9g vagy az ellen\u0151rz\u00e9si hat\u00e1r\u00e9rt\u00e9kek kisz\u00e1m\u00edt\u00e1s\u00e1ra szolg\u00e1l\u00f3 k\u00e9pleteket. A legfontosabb, hogy meg\u00e9rtsd, mi\u00e9rt csin\u00e1lod. <\/strong><\/p>\n\n\n\n

2. Nem megfelel\u0151 int\u00e9zked\u00e9sek<\/h3>\n\n\n\n

Az SPC bevezet\u00e9sekor elk\u00f6vetett egyik leggyakoribb hiba, hogy nem tulajdon\u00edtanak el\u00e9g nagy jelent\u0151s\u00e9get a m\u00e9r\u00e9snek. Val\u00f3j\u00e1ban a kontrollgrafikon \u00e9s a k\u00e9pess\u00e9g kisz\u00e1m\u00edt\u00e1sa mindenekel\u0151tt a pontos \u00e9s megb\u00edzhat\u00f3 m\u00e9r\u00e9sekt\u0151l f\u00fcgg. Ha ez nem \u00edgy van, akkor minden int\u00e9zked\u00e9s rossz eredm\u00e9nyeken alapul, \u00e9s nem hozza meg a v\u00e1rt eredm\u00e9nyeket.<\/p>\n\n\n\n

Az SPC-megk\u00f6zel\u00edt\u00e9s bevezet\u00e9se el\u0151tt fontos biztos\u00edtani, hogy a m\u00e9r\u00e9si folyamatok megism\u00e9telhet\u0151k legyenek, \u00e9s ennek nincs jobb m\u00f3dja, mint a megfelel\u0151 Gage R&R elv\u00e9gz\u00e9se.<\/p>\n\n\n\n

3. Tudni, hogyan kell reag\u00e1lni<\/h3>\n\n\n\n

Ha egy kontrollgrafik\u00e1t \u00e1ll\u00edtanak fel, nyilv\u00e1nval\u00f3nak t\u0171nik, hogy azt figyelemmel kell k\u00eds\u00e9rni, \u00e9s ha elt\u00e9r\u00e9st \u00e9szlelnek, a folyamatot korrig\u00e1lni kell. A val\u00f3s\u00e1gban azonban nem mindig ez a helyzet. Ennek f\u0151 oka az, hogy az \u00fczemeltet\u0151 nem mindig tudja, hogyan reag\u00e1ljon az elt\u00e9r\u00e9sre. Ez\u00e9rt meg kell adni nekik a kulcsokat \u00e9s egy reakci\u00f3szabv\u00e1nyt.<\/p>\n\n\n\n

4. T\u00fal sok ellen\u0151rz\u00e9si szab\u00e1ly<\/h3>\n\n\n\n

T\u00fal sok reakci\u00f3szab\u00e1ly van az SPC-ben, x pont az \u00e1tlag felett, y pontok v\u00e1ltakoz\u00e1sa stb. B\u00e1r mindegyik szab\u00e1ly relev\u00e1ns, mindegyiknek van egy hib\u00e1ja - megt\u00f6rt\u00e9nhet puszta v\u00e9letlen folyt\u00e1n. Igaz, a hamis pozit\u00edv val\u00f3sz\u00edn\u0171s\u00e9ge alacsony, 0,3%, de ha 15 azonos t\u00edpus\u00fa szab\u00e1lyt egym\u00e1sra helyez\u00fcnk, a hamis pozit\u00edv val\u00f3sz\u00edn\u0171s\u00e9ge 4,5% lesz. Ez azt jelenti, hogy \u00e1tlagosan 20-b\u00f3l egy reakci\u00f3szab\u00e1ly jelenik meg minden val\u00f3s ok n\u00e9lk\u00fcl. Ez\u00e9rt c\u00e9lszer\u0171 a szab\u00e1lyok sz\u00e1m\u00e1t mind\u00f6ssze 2 vagy 3 szab\u00e1lyra korl\u00e1tozni.<\/p>\n\n\n\n

5. Nem megfelel\u0151 szersz\u00e1mok<\/h3>\n\n\n\n

Egy SPC fel\u00e1ll\u00edt\u00e1sa el\u00e9g bonyolult. Ha az oper\u00e1toroknak meg kell tanulniuk egy \u00faj eszk\u00f6z haszn\u00e1lat\u00e1t is, az igazi kih\u00edv\u00e1s. Ehhez a k\u00f6vetkez\u0151kre van sz\u00fcks\u00e9g haszn\u00e1ljon eszk\u00f6zt<\/a> amely egyszerre rendk\u00edv\u00fcl k\u00f6nnyen kezelhet\u0151 a kezel\u0151k sz\u00e1m\u00e1ra (nem ig\u00e9nyel k\u00e9pz\u00e9st) \u00e9s el\u00e9g \u00e1tfog\u00f3 a technikusok sz\u00e1m\u00e1ra a fejlett elemz\u00e9sek elv\u00e9gz\u00e9s\u00e9hez. Ismer\u00fcnk egyet, amely nagyon j\u00f3l v\u00e9gzi a feladat\u00e1t...<\/p>\n\n\n\n
