- An assembly line is to be designed to operate 13 hours per day and supply a steady demand of 325 units per day. Here are the tasks and their performance times: TASK PRECEDINGTASKS PERFORMANCE TIME (SECONDS) TASK PRECEDINGTASKS PERFORMANCETIME (SECONDS) a — 48 g d 43 b — 58 h e 38 c — 73 i f 23 d a 63 j g 33 e b 88 k h, i 53 f c 23 l j, k 67 A) What is the efficiency of your line balance? B) Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 13 hours per day in regular time. (Round your answers to the nearest whole number.)Dave Grubbs of Grubbs Auto Body has five cars waiting for Economy Detailing. An Economy Detailing consists of a wash and then a hand wax.

For the schedule in question “a”, how many hours is the waxing task idle? When will Dave finish the Cadillac? What is the average order completion time?Canine Kernels Company (CKC) manufactures two differenttypes of dog chew toys (A and B, sold in 1,000-count boxes)that are manufactured and assembled on three differentworkstations (W, X, and Y) using a small-batch process (seeFigure 5.12). Batch setup times are negligible. The flowchartdenotes the path each product follows through the manu-facturing process, and each product’s price, demand perweek, and processing times per unit are indicated as well.Purchased parts and raw materials consumed during pro-duction are represented by inverted triangles. CKC can makeand sell up to the limit of its demand per week; no penaltiesare incurred for not being able to meet all the demand. Eachworkstation is staffed by a worker who is dedicated to workon that workstation alone, and is paid $6 per hour. Totallabor costs per week are fixed. Variable overhead costs are$3,500/week. The plant operates one 8-hour shift per day, or40 hours/week. Which of the three workstations, W, X, or Y,has the highest…
- DEFINE CONWIP (CONstant Work-In-Process)A production process at Kenneth Day Manufacturing is shown in the figure below.

Determine the overall process rolled throughput yield. Plot the results. Describe manufacturing, business process, and/or Six Sigma project situations for the origination of this data. Include example operation steps to monitor. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.There are six wires which need to be attached to a circuit board. A robotic device will attach the wires. The wires can be attached in any order, and the production manager wishes to determine which order would be fastest for the robot to use. Use the multiplication rule of counting to determine the number of possible sequences of assembly that must be tested. (Hint: There are six choices for the first wire, five for the second wire, four for the third wire, etc.)
