He mea hana ia ka inspection akā ʻo ka nonvalue-hoʻohui hoʻohui i ka hana, a ʻo kā mākou pahuhopu ke hana ma ke kūlana liʻiliʻi, ke hoʻolako ʻia e hoʻokō mākou i nā koina o ka mea kūʻai. ʻO ka helu ʻono ʻokoʻa a (c = 0) i ka hoʻolālā laʻana e pono ai ka nānā ʻana ma mua o ka hoʻolālā ANSI / ASQ Z1.4 (a mua ʻo MIL-STD 105), a lilo i ka wā i hilinaʻi nui ʻia ka mea hoʻolako ma kona pae haʻahaʻa.
Kahi papahana ANSI / ASQ Z1.4 he kiko hoʻohālikelike ia n, a me kahi helu e c. Na ka mea nānā ke nānā aku i nā huahana, a e ʻae aku i ka nui inā loaʻa nā hapa a i ʻole nā hapa liʻiliʻi a i ʻole nā loea. Hoʻonohonoho kēia mau hoʻolālā e hāʻawi (kahi liʻiliʻi) i kahi manawa 95-kaila o ka ʻae ʻia a hiki i ke pae ʻae ʻia i ʻae ʻia (AQL), ʻo ia kekahi o nā hoʻohālike no ke koho ʻana o ka hoʻolālā.
ʻO William A. Levinson, PE, FASQ, CQE, CMQOE ke poʻokela o Levinson Productivity Systems PC a me ka mea kākau o ka puke The Expaded and Annotated My Life and Work: Henry Ford's Universal Code for World-Class Success.
Ua aʻo ʻia wau i kā Squeglia c = 0 hoʻolālā ma Malaki o 2018. Makemake wau e ʻike i ka loiloi helu a Squeaglia e wehewehe i ka nui o ka laʻana.
Ua heluhelu wau i kāna puke, 5th edition akā ʻaʻole maopopo. No laila, mahalo nui wau iā ʻoe no kāu ʻatikala. A he nīnau kaʻu i kāu ʻatikala.
Ma kā Squeaglia puke, ua haʻi ʻo ia ua hoʻohana ʻo ia i ka distirbution Hypergeometric no ka helu pono hou ʻana, akā ua hoʻohana wale ʻoe i ka mahele Binomial
Ma ka puke ʻelima, "Nā Manaʻo Hoʻohālikelike Helu ʻApono", ʻaʻole hiki iaʻu ke ʻike pehea e helu ai i ka nui o n.
Mahalo iā Mr. Levinson no kāna pepa ma C = 0 hoʻolālā laʻana. ʻO ke kumu hoʻohālikelike ka nui i hōʻike ʻia i kāna pepa kekahi o nā pono pono e loaʻa. Makemake wau e hoʻohui i kēia mau mea ma lalo o AS9138 a me ARP9013 ua hoʻohālikelike ʻia nā wehewehe ʻana no ka pae e like me ka ʻae ʻia (AQL), Point Pilikino Kaulike (ERP), Lot Tolerance Percent Defective (LTPD), a me Rejectable Quality Level (RQL). He mau helu ʻokoʻa wale nō lākou ma ka pihi hana like like me ka likelike o ka ʻae ʻia 0.90-0.95, 0.50, 0.10, a me 0.05 pākahi. Ma ke kaua honua ʻelua, ua haʻalele ʻia ke kuhi manaʻo o ka mea kūʻai (LTPD) i ka manaʻo o ka mea hana (AQL) no ka mea, e like me kā HR Bellinson i ʻōlelo ai; Ke kūʻai ʻia nei nā mea like he 20,000,000 mai 50 a ʻoi paha o nā mea hoʻolako ʻokoʻa, a ua manaʻo ʻia he ac = 0 ka hoʻolālā laʻana kūpono ʻole i nā mea hoʻolako liʻiliʻi; e hōʻole pinepine nei i kā lākou huahana ma mua o nā huahana mea hoʻolako nui e loaʻa ana ka pae pono like (ASA 105th makahiki hālāwai, Ianuali 27th 1946.). ʻOiaʻiʻo hiki i nā hoʻolālā laʻana AQL ke loaʻa nā laʻana nui aʻe ma mua o nā hoʻolālā c = 0 i mea e "kūlou" i ke ʻano o ka hana ma ka kiko AQL e hāʻawi ana i kahi likelike kiʻekiʻe o ka ʻae ʻia, ʻoiai e paʻa ana i kahi kiko LTPD o ka mea kūʻai. He kūpono ʻole ke ʻōlelo aʻe aia kahi papahana A = 0 kahi AQL no ka mea ma o ka hoʻolālā ʻana, ʻo kāna kuhi kiko ka mea kūʻai, ʻaʻole ka mea hana. ʻO kēia ke kumu o ka 0.542 hiki ke ʻae ʻia i ka laʻana a Mr. Levinson me n = 15, c = 0 no ka nui he 4% nonconforming (4.0 AQL). ʻAʻole hiki iā mākou ke hoʻolālā i kahi set of c = 0 mau hoʻolālā laʻana me ka manaʻo o ka mea hana. ʻO kēia ke kumu nui a me ka hānau ʻana o nā hoʻolālā Sampling AQL i hoʻokumu ʻia.
Me ka manaʻo o ka mea kūʻai aku - ʻO kahi hoʻolālā laʻana e ʻike nei i nā nonconformities i ka hapa nui o ka manawa, ke hana nei i kāna hana i manaʻo ʻia a no laila ʻaʻole pono e hoʻopaʻa ʻia. ʻO ka manawa wale nō e kuhikuhi ai ka hoʻokele waiwai o ke kūlana i ka lilo o ka ʻimi ʻana i kekahi mau mea pili ʻole ma mua o ka uku o ka nānā hou ʻana e hoʻopaʻa mākou i ka nānā.
Nui a hewahewa nā kaʻina hana e like me MIL-STD-105, MIL-STD-1916, APR9013, a me AS9138 e inoa ai i kekahi. ʻO ka hapa nui o ka poin-of-view ʻokoʻa a lilo i mea piʻoloke iki, akā mahalo nō e mau ana ka makemakika ma lalo a hōʻike he ʻokoʻa lipstick kala ʻokoʻa ia ma ka OC Curve like.
