(l) A model used to estimate or predict the extent of deviation of the behavior of an actual system from the desired behavior of the system; for example, a model of a communications channel, used to estimate the number of transmission errors that can be expected in the channel. (2) In software evaluation, a model used to estimate or predict the number of remaining faults, required test time, and similar characteristics of a system. [DIS; IEEE]
(l) Yimodeli esetyenziswa ekuthelekeleleni okanye ukuthelekelela ulwandiso lophambuko lokuziphatha kwento yokwenene esuka kukuziphatha okunqwenelekayo kwenkqubo, umzekelo, umjelo wothungelwano lwemodeli, edla ngokusetyenziselwa ukuthelekelela inani leempazamo ezidlulisiweyo ezinokuthi zilindeleke kumjelo. (2) Kuvavanyo lwe-software, imodeli isetyenziselwa ukuthelekelela okanye ukuqikelela inani elishekileyo levolthsi ezishekileyo, ixesha lokuvavanya elishekileyo, kunye neempawu zenkqubo eziyeleleneyo kulo.
