Lub rooj sib dhos ua ke yog cov khoom lag luam tshwj xeeb-qhia txheej txheem. Cov kab sib dhos yog hais txog cov kab txuas ntxiv uas txuas nrog los ntawm qee cov khoom siv tuav khoom. Kev sib dhos kab yog lub thev naus laus zis tseem ceeb. Nws tuaj yeem hais tias ib qho khoom kawg nrog ntau qhov chaw thiab cov khoom lag luam loj tau tsim rau qee qhov los ntawm kev sib dhos kab. Yog li no cov txheej txheem ntawm lub rooj sib dhos kab yog cuam tshuam los ntawm ntau yam xws li cov khoom siv sib dhos kab, cov khoom lag luam, cov neeg ua haujlwm, logistics thiab cov txheej txheem ntau lawm.
Nws feem ntau suav tias qhov kev yeej ntawm lub rooj sib dhos kab yog qhov xwm yeem thiab lub sijhawm ua haujlwm ntawm txhua qhov haujlwm kis yog qhov sib luag. Txawv ntawm cov sibtham muaj qhov sib txawv zoo, feem ntau yog thaws hauv:
1. Khoom siv tuav cov khoom siv (txoj siv sia lossis conveyor, crane) ntawm txoj kab sib dhos
2. Hom ntawm cov kab ntau lawm kab (hom U, hom ncaj, ceg hom)
3. Tuav daim ntawv tswj hwm (lub cev muaj zog, tib neeg muaj suab nrov)
4. Sib dhos ntau yam (ib qho khoom lag luam lossis ntau yam khoom lag luam)
5. Kev sib dhos ua haujlwm kab ua haujlwm (cov neeg ua haujlwm tuaj yeem zaum, sawv ntsug, ua raws kab kev sib dhos lossis txav mus nrog kab kev sib dhos, thiab lwm yam)
6. Ntev ntawm cov kab sib dhos (ob peb lossis ntau tus neeg ua haujlwm)
