Q4

We consider flight check-in desks in an Airport. The administration of the airport wants to improve its quality of service by reducing the waiting time of travelers. For that purpose, they want to design what could be the best queuing strategy to have the minimum waiting time. The main problem is to know what is the best queuing strategy that reduces the waiting time of travelers in check-in desks.

Discuss the Model Development Lifecycle in relation to the case described above.

b)The processing time of documents depends on the number of applications opened on a system. Data on the procession times of word documents and the number of documents opened on the system are given below:

Processing

Time(s)12.53426

Number of

documents245638

i)Determine the model that can be used to predict the processing time

of the system and

ii) Determine the amount of variability explained by the model

iii)determine the estimated processing time given seven documents are been processed
