STATISTICAL PROCESS CONTROL (SPC) BASICS

Statistical process control (SPC) ndikugwiritsa ntchito njira zowerengera pakuwunika ndikuwongolera njira kuti zitsimikizire kuti zimagwira ntchito momwe angathere kuti apange zinthu zofananira. Pogwiritsa ntchito SPC, njira zimakhala zodziwikiratu kuti zitha kupanga zinthu zofananira ndi zinyalala zomwe zingatheke. Ngakhale SPC yakhala ikugwiritsidwa ntchito powongolera mizere yopangira, imagwiranso ntchito mofanana ndi njira iliyonse yokhala ndi zotuluka zoyezeka. Zida zazikulu za SPC ndi ma chart owongolera, zomwe zimayang'ana pakusintha kosalekeza ndi kuyesa kopangidwa (DOE).

 

Mphamvu zambiri za SPC zagona pakutha kufufuza njira ndi magwero a kusintha kwa njirayo pogwiritsa ntchito zida zomwe zimapatsa mphamvu kusanthula kwamalingaliro pamalingaliro okhazikika komanso zomwe zimalola mphamvu ya gwero lililonse kutsimikiziridwa ndi manambala. Kusiyanasiyana kwa zochitika zomwe zingakhudze ubwino wa chinthu chomaliza kapena ntchito zingathe kuzindikiridwa ndi kukonzedwa, motero kuchepetsa zinyalala komanso mwayi woti mavuto adzaperekedwa kwa makasitomala. Pogogomezera kuzindikira koyambirira ndi kupewa mavuto, SPC ili ndi mwayi wosiyana ndi njira zina zabwino, monga kuyang'anira, zomwe zimagwiritsa ntchito zothandizira kuti zizindikire ndi kukonza mavuto pambuyo pake.

 

Kuphatikiza pa kuchepetsa zinyalala, SPC ikhoza kuchepetsa nthawi yofunikira kupanga chinthu kapena ntchito kuchokera kumapeto mpaka kumapeto. Izi zimachitika pang'ono chifukwa cha kuchepa kwa mwayi woti chomalizacho chiyenera kukonzedwanso, koma zingabwerenso chifukwa chogwiritsa ntchito deta ya SPC kuti mudziwe zolepheretsa, nthawi zodikira, ndi zina zomwe zingachedwetsedwe mkati mwa ndondomekoyi. Kuchepetsa nthawi yozungulira komanso kusintha kwa zokolola zapangitsa SPC kukhala chida chofunikira pakuchepetsa mtengo komanso kukhutitsidwa kwamakasitomala.

Statistical Process Control (SPC) ikhoza kugawidwa m'magulu atatu:

1. Kumvetsetsa ndondomeko,

2. Kumvetsetsa zomwe zimayambitsa kusiyanasiyana,

3. Kuchotsa magwero a zifukwa zapadera zosiyana

 

Kuti mumvetsetse ndondomekoyi, ndondomekoyi imayang'aniridwa ndikuwunikidwa pogwiritsa ntchito ma chart chart. Ma chart owongolera amagwiritsidwa ntchito kuzindikira kusiyanasiyana komwe kungakhale chifukwa chazifukwa zapadera, komanso kumasula wogwiritsa ntchito ku nkhawa za kusiyanasiyana chifukwa cha zomwe wamba. Ma chart owongolera amapangitsa kumvetsetsa kwa njirayi kukhala ntchito yopitilira. Ndi ndondomeko yosasunthika yomwe siyambitsa malamulo odziŵika a tchati chowongolera, kusanthula luso la ndondomeko kumachitidwanso kuti awone luso lamakono kuti apange zinthu zogwirizana (zinthu zomwe zili mkati mwazofunikira).

 

Pamene, kupyolera mu ma chart olamulira, kusiyanasiyana komwe kumachitika chifukwa cha zifukwa zapadera kumazindikiridwa, kapena mphamvu ya ndondomeko ikupezeka kuti ikusowa, kuyesetsa kowonjezera kumayesedwa kuti mudziwe zomwe zimayambitsa kusiyana kumeneku ndikuzichotsa. Zida zomwe zimagwiritsidwa ntchito pochita izi zikuphatikiza zithunzi za Ishikawa, Design of Experiments (DOE) ndi ma chart a Pareto. Mayesero opangidwa (DOE) ndi ofunika kwambiri pa gawo ili la SPC, chifukwa ndi njira yokhayo yodziwira kufunikira kwazinthu zambiri zomwe zingayambitse kusiyana.

 

Zomwe zimayambitsa kusiyanasiyana zikadziwika, kuyesayesa kumagwiritsidwa ntchito kuthetsa zifukwa zomwe zili zonse mwachiwerengero komanso zofunikira. Izi zikutanthawuza chifukwa chomwe chili ndi zotsatira zochepa chabe koma zowerengetsera sizingaganizidwe kukhala zotsika mtengo kukonza; ndipo kumbali ina, chifukwa chomwe sichili chofunikira kwambiri sichingaganizidwe kukhala chofunikira. Njira zowonjezera zingafunike, makamaka ngati pali vuto ndi luso la ndondomeko.

 

DESIGN OF EXPERIMENTS (DOE)

Design of Experiments, kapena experimental design, (DoE) ndi njira yodziwira mgwirizano pakati pa zinthu zomwe zimakhudza ndondomeko ndi zotsatira za ndondomekoyi. Mwa kuyankhula kwina, amagwiritsidwa ntchito kupeza maubwenzi oyambitsa-ndi-zotsatira. Izi ndizofunikira kuti muzitha kuyang'anira zolowetsa kuti mukwaniritse bwino zomwe zatuluka. Nthambi iyi ya ziwerengero zogwiritsidwa ntchito imayang'anira kukonzekera, kuchititsa, kusanthula ndi kutanthauzira mayeso oyendetsedwa kuti awunike zinthu zomwe zimawongolera mtengo wa parameter kapena gulu la magawo. Zoyeserera zokonzedwa mwaluso komanso zoyeserera zitha kupereka chidziwitso chochuluka chokhudza kusinthika kwamayankhidwe chifukwa cha chinthu chimodzi kapena zingapo. Design of experiments (DOE) ndi njira yomwe imagwiritsa ntchito kwambiri sayansi yachilengedwe komanso chikhalidwe cha anthu.

 

Akatswiri athu odziwa kupanga ndi okonzeka kukutsogolerani pakukhazikitsa malingaliro a SPC ndi DOE pakampani yanu. Kutengera kusankha kwanu, titha kukuthandizani patali kapena kubwera ndikukhazikitsa kachitidwe ka Statistical Process Control (SPC) pamalo anu.
