Pa gawo ili, kayendetsedwe ka ntchito kafotokozedwa momveka bwino: kuyambira kufika kwa zipangizo zopangira, kudzera mu kukonza pa malo aliwonse ogwirira ntchito, kudzera mu kuyang'anitsitsa, mpaka ku chinthu chomalizidwa. Malire ndi malingaliro a dongosolo amafotokozedwanso.
4. Kukhazikitsa chitsanzo mu mapulogalamu
Ma model amalembedwa mu mapulogalamu oyeserera monga Arena, AnyLogic, FlexSim, Simio, kapena kugwiritsa ntchito zilankhulo zopanga mapulogalamu monga Python ndi malaibulale enaake.
5. Kutsimikizira ndi kutsimikizira
Kutsimikizira kumaonetsetsa kuti chitsanzocho chikugwira ntchito monga momwe chinapangidwira (palibe zolakwika zomveka). Kutsimikizira kumatsimikiza kuti chitsanzocho chikuyimira zochitika zenizeni, mwachitsanzo poyerekeza zotsatira zoyeserera ndi deta yakale monga momwe zimachitikira kapena nthawi yodikira yapakati.
6. Kuyesera kwa zochitika ndi kusanthula zotsatira
Chitsanzocho chikangogwira ntchito, makampani amatha kuyendetsa zochitika zosiyanasiyana: kuwonjezera makina, kusintha mapangidwe, kusintha malamulo otumizira, kusintha chiwerengero cha ogwiritsa ntchito, kapena kusintha kukula kwa batch. Zotsatira zake zimasanthulidwa pogwiritsa ntchito miyeso yoyenera.
7. Malangizo ndi kukhazikitsa
Zotsatira za kuyeserera zimasandutsidwa zisankho. Ngati pakufunika, kuyeserera kwina kumachitika pambuyo poti zoletsa zatsopano zapezeka.
Zitsanzo za Kugwiritsa Ntchito Kuyeserera Pokonzekera Kupanga
Kuyeserera kungagwiritsidwe ntchito m'mbali zosiyanasiyana za kukonzekera kupanga ndi kukonza, kuphatikizapo:
- Kusanthula kwa bottleneck: Kuzindikira malo ogwirira ntchito omwe nthawi zambiri amaletsa kufalikira kwa ntchito ndi njira zina zoyesera monga kuwonjezera makina, kugawanso ntchito, kapena kusintha ndondomeko ya njira.
- Kukonzekera kuthekera: Kuwunika ngati mphamvu zomwe zilipo panopa zili zokwanira kukwaniritsa zomwe zikuyembekezeredwa, komanso nthawi yomwe ndalama zatsopano zikufunika.
- Kukonza nthawi ndi malamulo ofunikira: Yerekezerani njira monga FIFO, nthawi yochepa yokonza, kapena zofunika kwambiri kutengera tsiku lomaliza kuti muwone momwe zimakhudzira nthawi yoperekera zinthu.
- Kukonza zinthu zomwe zili mu inventory ndi WIP: Kuyesa kukula kwa zinthu zomwe zili mu inventory, ndondomeko zokonzeranso zinthu, kapena makina okokera zinthu (monga Kanban) kuti muchepetse zinthu zomwe zili mu inventory popanda kuchepetsa ntchito.
- Kapangidwe ka kapangidwe ka zinthu ndi kagwiritsidwe ntchito kake: Kuyesa kusintha kwa mtunda woyenda, malo osungiramo zinthu, kapena kuchuluka kwa ma forklift/AGV kuti akonze bwino ntchito.
Mwachitsanzo, fakitale yopanga zida zamagalimoto nthawi zambiri imakumana ndi kuchedwa kotumizira zinthu chifukwa cha mizere yayitali yomaliza makina. Pogwiritsa ntchito zoyeserera, gululo likhoza kuyesa njira zingapo: kuwonjezera ma shift a opareshoni, kufulumizitsa kukhazikitsa ndi SMED, kapena kugula makina atsopano. Zotsatira za zoyeserera zitha kuwonetsa kuti kuwonjezera ma shift ndikotsika mtengo kwambiri pakanthawi kochepa kuposa kuyika ndalama mu makina, chifukwa zovuta zimachitika nthawi zina chifukwa cha nthawi zosalinganika.
Ubwino Waukulu wa Kuyeserera
Ubwino wa kuyerekezera pakukonzekera kupanga ukhoza kufotokozedwa motere:
1. Chepetsani chiopsezo cha zisankho: Popeza zochitika zimayesedwa pa intaneti, zisankho zimakhala zosavuta kuziyerekeza.
2. Kumapulumutsa ndalama zoyesera: Kuyesa thupi nthawi zambiri kumakhala kokwera mtengo komanso kumasokoneza magwiridwe antchito.
3. Kumvetsetsa machitidwe ovuta a dongosolo: Kuyerekezera kumathandiza kuwona momwe zinthu zikuyendera, mizere, ndi momwe zinthu zikuyendera pakati pa njira.
4. Imathandizira kusintha kosalekeza: Kuyerekezera kungagwiritsidwe ntchito mobwerezabwereza ngati pali kusintha kwa zinthu, zopempha, kapena mfundo.
