Elaine owns a computer rental store. The rental process can be depicted by the following process flow diagram. 

Customer arrivals to the store with an average rate of R = 20 per week and each customer requests for one computer. The rental time is 3 weeks on average. The rental fee is $300 per week. At the end of the rental period, the customer returns his/her rented computer to the store. Elaine will inspect every returned computer. The inspection time is negligible. % of the returned computers need to be repaired by a technician (repair actually means re-configuration and minor repair). A computer that needs repair spends an average time of 1 week in the repair stage, including waiting and repair. After repair work is completed, the computer will be put into the stock for rental. Returned computers that don’t need repair will be put immediately into the stock for rental. To ensure that there are always computers available to satisfy customer requests, Elaine has to keep an average of 10 computers in the stock for rental. 

(a) What is the total number of computers that Elaine needs her rental business? 

(b) With an average of 10 computers in the stock for rental, on average how much time does a computer spend the stock for rental before it is rented by a customer? 

(c) Elaine estimates that the average rental time will become 2 weeks if she increases the rental fee $500 per week. The customer arrival rate, the repair time and the percentage of computers that need repair will remain the same. Again, she needs to have an average of 10 computers in the stock for rental. Should she increase the rental fee? Justify your answer by considering the number of computers required and the expected revenue per week.

Compose a 2750 words assignment on impact of ict on every aspect of life. Needs to be plagiarism free! ICTs have connected the people together through social networking provided by mobile phones, personal computers and internet. People are able to help each other and even get married by means of this electronic means of interaction. Distance doesn’t matter since people are only a phone call away from each other. This way people travel more often for business or pleasure and still manage to stay connected at office or home. International trade has been increased with the help of information and communication technologies. This global trade includes goods and services being exchanged among different nations. Service industries which especially include public relations and public communication management have also experienced high growth in productivity and profitability by adopting ICTs (Sapprasert 2010). Call centers and software houses are the most successful examples of international trade taking place in terms of services. Thus, the developed countries get their required services at a very low rate while the developing and underdeveloped countries benefit from the foreign trade which brings earning opportunities and reduces poverty for them. The interdependency of different economies resulting through globalization has also brought challenges along with its benefits. such challenges include the current economic crisis worldwide, internet scams, etc.
