...expected number of customers that will arrive in a five-minute period? The expected number is of 0.4*5 = 2 customer is a five-minute period. b) Assume that the Poisson probability distribution can be used to describe the arrival process. Use the arrival rate in part (a) and compute the probabilities that exactly 0, 1, 2, and 3 customers will arrive during a five-minute period. The probabilities of the described scenarios are as follows: P0=20e-20! P0=0.135335283 P1=21e-21! P1=0.270670566 P2=22e-22! P2=0.270670566 P3=23e-23! P3=0.180447044 c) Delays are expected if more than three customers arrive during any five-minute period. What is the probability that delays will occur? This probability can be expressed as the probability of more than 3 customers arriving during the five-minute period, which can be computed as following: P(x > 3) = 1 – P(x ≤ 3) P (x > 3) = 1 – 0.85712346 P(x > 3) = 0.14287654 Thus, there is a 14, 29% probability of expected delays in five-minute period. Problem 3 Use the single-server drive-up bank teller operation referred to in Problems 1 and 2 to determine the following characteristics for the system: Using arrival rate and service rate PER MINUTE a) The probability that no customers are in the system P0=1- 0.40.6 P0=0.3333 b) The average number of customers waiting Lq=0.420.6(0.6-0.4) Lq=1.3333 c) The average number of customers waiting L = 1.3333 + 0.40.6 L = 2 d) The average time a customer’s...

...Al Kobaisi Group is a ready mix company which has three plants in various locations among Kingdom of Bahrain. They signed a contract with Al-Moayed contracting to supply them with concrete mix for three different projects located at three different areas. The following tables show the amount of concrete mix each plant can provide and required quantities for each project: Al Kobaisi Group Plants | Supply | P1 | 200 m3/day | P2 | 450 m3/day | P3 | 325 m3/day | Project Name | Demand | M1 | 100 m3/day | M2 | 375 m3/day | M3 | 500 m3/day | Al Kobaisi Group will rent the trucks from a transportation company to transfer the concrete mix from the plants to the sites. Sales manager of Al Kobaisi Group wants to know the optimum way of assignment of trucks in which the cost will be minimum. Use the below table in order to help the manager in taking the decision using one of the L.P models. P/M | M1 | M2 | M3 | Supply | P1 | 20 | 5 | 13 | 200 | P2 | 9 | 18 | 7 | 450 | P3 | 11 | 16 | 23 | 325 | Demand | 100 | 375 | 500 | | In order to solve the above mentioned problem we are going to use transportation model.

Resource Management Task Scheduling The task scheduling goals of Cloud computing is provide optimal tasks scheduling for users, and provide the entire cloud system throughput and QoS at the same time. Scheduling is the process of allocating tasks to available resources on the basis of tasks need [5].The main purpose for scheduling is to maximize the utilization of resources. Following are the needs of job scheduling in cloud computing: CPU utilization – keep the CPU as busy as possible (from 0% to 100%) Throughput – # of processes that complete their execution per time unit Turnaround time – amount of time to execute a particular Process Waiting time – amount of time a process has been waiting in the ready queue...

...Unit 1: The business environment Help sheet 1.1.1 P1 Describe the type of business, purpose and ownership of two contrasting businesses To achieve P1, you must complete Task sheet 1.1.1, a case study, as well as Worksheets 1.1.1 to 1.1.4. You must also write a detailed presentation about two organisations. • You must ensure that the two organisations chosen are very different. For example, a large plc, such as Tesco, and a charity, such as Save the Children. This will make it easier to compare the environments. • It is a good idea to choose organisations that you are interested in, but that also have a large amount of information available. Therefore, spend some time researching a few organisations that might be of interest to see which one will make this task the easiest. • The same organisations will be used for tasks other than P1 so look ahead in the assignment to make sure the information you will need is available. • Once you have chosen your organisations, you need to research them in order to be able to identify the type of businesses they are. You must identify which scale they operate at and what sector they operate in. Make sure you give evidence and reasoning to back up your decisions. • The purpose and ownership of a business can often be seen on its website. However, you may find a phone interview very useful for collecting all the information you need. This can then be used as evidence. Remember to reference your work when necessary. ...
