Ngokukhiqizwa okuncane, kungakhethwa ukulawula okuzimele, okulungele ukusebenza futhi konga izindleko. Emigqeni yokukhiqiza emikhulu, singenza ngezifiso amasistimu wokulawulwa okuzenzakalelayo ukwenza lula ukuphathwa nokusebenza, futhi sisebenzise amafomula wedatha ukufeza ukukhiqizwa komkhiqizo ohlukahlukene.
Sineqembu lokuzenzela elizenzakalelayo, futhi sihlanganisa imishini yokukhiqiza ukudla ezigabeni ezahlukahlukene zokucubungula, xhuma ngokugcwele imishini ezimele ngokulawulwa kohlelo, futhi sihlanganise nepulatifomu yokusebenza ebonakalayo ukuze sikuqonde ukusebenza okuzenzakalelayo kolayini wokukhiqiza.
Ulayini wokukhiqiza usebenzisa i-PLC nezinye izingxenye zokulawula ezimaphakathi, kuhlanganiswe nesiguquli semvamisa nesistimu yedrayivu yokuqinisekisa ukunemba nokusebenza kahle kwemishini yokusebenza.
