A proposed production system consists of five serial automatic workstations. The processing times at each workstations are constant: 11, 10, 11, 11 and 12 (all times given in this problem are in minutes). The part interarrival times are UNIF(13 ,15). There is an unlimited buffer in front of all workstations, and we will assume that all transfer times are negligible or zero. The unique aspect of this system is taht at Workstations 2 through 5 there is a chance that the part will need to be reprocessed by the workstations that precedes it. For example, after completion at Workstation 2, the part can be sent back to the queue in front of Workstation 1. The probability of revisiting a workstation is independent in that the same part could be sent back many times with no change in the probability. At present, it is estimated that this probability, the same for all four workstations, will be between 5% and 10%. Develop the simulation model and make six runs of 10,000 minutes each for probabilities of 5, 6, 7, 8, 9, and 10%.

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.

You have been supporting csm tech publishing's windows server 2016 server network for over a year. the office has two windows server 2016 servers running active directory and a number of other roles. management has informed you that a small sales office is opening in the same building three floors up. the sales manager wants to install a sales application on a server located in the sales office. this server will have limited physical security because there's no special room dedicated for it, which means it will be accessible to non-it personnel and visitors. you're considering installing windows server 2016 server core on the new server because accessing its console regularly probably won't be necessary, and this server will be managed from one of the other csm tech publishing servers. what are the benefits and drawbacks of using server core for this branch office? what are some things you should do to set up this server management environment?
