Calculations.
To complete this assignment, consider the following scenario:
A disk drive has 300 cylinders, numbered 0 to 299. The drive is currently serving a request at cylinder 51, and the previous request was at cylinder 56. The pending requests are received in the following order: 72, 56, 103, 111, 17, 189, 236, 198, and 88.
Describe how the disk arm moves to satisfy all the pending requests for each of the following disk-scheduling algorithms. (Perhaps you create a diagram similar to the diagrams in Section 9.4 to support your explanation.)
FCFS
SSTF
SCAN
Calculate the total distance (in cylinders) that the disk arm moves for each of the above disk-scheduling algorithms. Compare the algorithms and explain which algorithm is the most efficient (the shortest distance) for this scenario. Write a minimum of 250 words.

Sample Solution
The client’s trust in a retailer will develop through a progression of fruitful exchanges, which incorporate returns handling (Hjort and Lantz, 2016). Writing calls attention to that lone a bunch of firms have well-performing methodologies to deal with returns, and numerous retailers will in general disregard the client returns proc Calculations edures, particularly firms with a customary inventory network approach (Shaharudin, Govindan, Zailani, Tan, and Iranmanesh, 2017). Client returns are items that don’t meet the client’s desires, and it is known to be an effective method to keep up consumer loyalty (Yang, Chen, Chen, and Chen, 2017). The way toward taking care of profits can be delineated as appeared in figure 5 (de Koster, de Brito, and van de Vendel, 2002, p.3). Figure 5. The way toward taking care of profits. Adjusted from ” How to sort out return taking care of: an exploratory investigation with nine retailer distribution centers,” by R.B.M. de Koster, M.P. de Brito, and M.A. van de Vendel, 2002, International Journal of Retail and Distribution Management, 30, p.3. Copyright 2002 by MCB UP Limited. Drivers of client returns are characterized as deformities, item inconsistency with buyer needs, and nonattendance of item execution in connection to the client desires (Rao, Rabinovich, and Raju, 2014). It is urgent for the retailer to appraise taking care of expenses and the clients’ expenses of restoring the item (Yang et al., 2017). Consequently, overseeing buyer returns adequately gets pivotal to business benefits (Ruiz-Benitez and Muriel, 2014). In addition, the profits procedure is approximated to be a few times as costly as their outbound shipment (Ruiz-Benitez and Muriel, 2014). Usually, costs are assigned with exercises, for example, repackaging, re-stocking and exchanging returns. Moreover, costs are made before the repackaging, re-stocking and exchanging exercises, for example, retail activities, and assortment and transport right now an arrival is broadcasted by a client. Anyway the vast majority of the retailers acknowledge CR costs as being unavoidable in working together (Rao, Rabinovich, and Raju, 2014), an organization can’t disregard that CR is surely connected with costs made all through the whole chain. Conveyance and return choices, and client inclinations have been seen as advancing after some time (Hübner, Holzapfel, and Kuhn, 2016). Preparing returns rapidly and proficiently has become central in light of the accompanying retail and client point of view reasons: the item will be sooner accessible on rack for resale and the clients’ desire in speedy repayment is satisfied. Thusly, firms will profit by adjusting their arrival choices to the developing client inclinations. In any case, directors experience issues in structuring, arranging and controlling the invert production network in which client returns are prepared (Blackburn, Guide, Souza, and Van Wassenhove, 2004)
