Hi! I need a little help with D. I can't figure out how to calculate the efficiency. Can you explain it to me? Williams Motor Manufacturing assembles small motors for sale to major appliance manufacturers around the world. Average demandfor its best-selling motor is 600 units per day. The assembly line operates continuously during a single 8-hour shift. The tasks required,task times, and precedence relationships are:TaskABCDEFGHHTime (seconds)122220201830172520PredecessorspictureClick here for the Excel Data FileACB,DEF,GHa. What is the takt time?b.

Canine Kernels 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 following figure). 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 working 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. The senior management at Canine…

Tailwind, Inc., produces high-quality but expensive training shoes for nmners. The Tailwind shoe, which sells for $210, contains both gas- and liquid-filled compartments to provide morestability and better protection against knee, foot, and back injuries. Manufacturing the shoes requires 10 separate tasks. There are 400 minutes available for manufacturing the shoes in the plant each day. Daily demand is 60. The information for the tasks is as follows: a) Draw the precedence diagram.b) Assign tasks to thl e minimum feasible number of workstations according to the "ranked positioned weight" decision rule.c) What is the efficiency of the process you completed in (b)?d) What is the idle time per cycle?
Francis Johnson’s plant needs to design an efficient assembly line to make a new product. The assembly line needs to produce 15 units per hour, and there is room for only four workstations. The tasks and the order in which they must be performed are shown in the following table. Tasks cannot be split, and it would be too expensive to duplicate any task. TASK TASK TIME (MINUTES) IMMEDIATE PREDECESSOR A 1 — B 2 — C 3 — D 1 A, B, C E 3 C F 2 E G 3 E What is the workstation cycle time required to produce 15 units per hour? Note: Round your answer to 1 decimal place. Balance the line to use the fewest possible workstations to meet the cycle time found in part (b). Use whatever method you feel is appropriate. What is the efficiency of your line balance, assuming the line operates at the cycle time from part (b)? Note: Round your answer to 1 decimal place.
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. Finally, task G can start only once task Fis completed.Given we apply the most remaining tasks rule for balancing the assembly line with ties broken according to longest task time firstthe tasks that will be assigned to the SECOND workstation are

Balance the assembly line shown below for (a) a shift output of 60 pieces and (b) a shift output of 40 pieces. Assume an 8-hour shift, and use the rule: choose the assignable task with the longest processing time. Compute the line efficiency for each case. Fill in the table below for a shift output of 60 pieces. Break ties by choosing the lowest task number. If your answer is zero, enter "0". Round your answers to the nearest whole number.
