- Alocal toy manufacturer is using a production line that runs 8 hours per day and produces a toy that requires a total of 7 tasks to be performed. The daily demand is 100 toys. Times of the tasks are 2.73, 2.01 201 2.13, 2.0, 2.61, 2.71 , and 2.95 minutes for A,B,C,D,E,F, and respectively. However, due to the nature of the product there are precedence rules that must be observed. Such that Task Adoes not need any predecessorsB requires task A to completed. To start task C and task Deach require task B to be completed. Task C must be completed prior to stating task E. Task F needs both task D and task Eto be completed.

- Draw a sequence diagram on this scenario. Consider an e commerce website, the customer will search for the items either by category, by price, by color or by size. the customer will add the selected items to the shopping cart. He/she can either continue shopping or can perform checkout. On checkout bill/invoice will be generated and the customer will enter personal information including email, phone and address; will choose cash on delivery option or card payment. If card payment selected, he/she will enter the card information. The bank object will validate the card, if validated the required amount will be deducted and the item will be dispatched to the provided address in both cases (COD/ valid card payment).arrow_forwardDiscuss the importance of standardization in process planning.arrow_forwardK Canine Kennels Company (CKC) manufactures two different types of dog chew toys (A and B, sold in 1,000-count boxes) that are manufactured and assembled on three different workstations (W, X, and Y) using a small-batch process (see the figure below). Batch setup times are negligible. The flowchart denotes the path each product follows through the manufacturing process, and each product's price, demand per week, and processing times per unit are indicated as well. Purchased parts and raw materials consumed during production are represented by inverted triangles. CKC can make and sell up to the limit of its demand per week; no penalties are incurred for not being able to meet all the demand. Each workstation is staffed by a worker who is dedicated to work on that workstation alone and is paid $6 per hour. Total labor costs per week are fixed. Variable overhead costs are $3,500/week. The plant operates one 8-hour shift per day, or 40 hours/week. Product A $2 Step 1 Station W (11 min) Raw…arrow_forward
