Tailwind, Inc., produces high-quality but expensive training shoes for runners. The Tailwindshoe, 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 shoesrequires 10 separate tasks. There are 400 minutes available for manufacturing the shoes inthe plant each day. Daily demand is 60. The information for the tasks is as follows: Task Performance Time (In minutes) Task Must Follow This task A 1 ___ B 3 A C 2 B D 4 B E 1 C.D F 3 A G 2 F H 5 G I 1 E,H J 3/25 I 1. What is the theoretical minimum number of work stations required to satisfy this output rate? 2. Allocate the tasks to work stations taking into consideration the precedence requirements and usingthe LOT rule to break ties between feasible tasks.

Please dont answer in image ormat,Do type. 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…

XYZ Company produces and sells 2 products, Lambda and Gamma, and the production process goes through two departments. Traditionally Manufacturing Overhead (M/O) cost is applied on the basis of direct labor hours (DLH); estimated M/O cost is $ 5,757,500 and the estimated DLH is $12,250 for the most recent period.The team decided to replace traditional plantwide costing system to activity-based costing system. There are 3 activity cost pools which represent 3 activity areas at the plant. Direct Labor wage rate is $ 30 per hour. Compute total cost per unit (for lambda and gamma) using activity-based approach. (round your numbers).
A linear programming computer package is needed. EZ-Windows, Inc., manufactures replacement windows for the home remodeling business. In January, the company produced 15,000 windows and ended the month with 9,000 windows in inventory. EZ-Windows' management team would like to develop a production schedule for the next three months. A smooth production schedule is obviously desirable because it maintains the current workforce and provides a similar month-to-month operation. However, given the sales forecasts, the production capacities, and the storage capabilities as shown, the management team does not think a smooth production schedule with the same production quantity each month possible. February March April Sales forecast 15,000 16,500 20,000 Production capacity 14,000 14,000 18,000 Storage capacity 6,000 6,000 6,000 The company's cost accounting department estimates that increasing production by one window from one month to the next will increase total costs by $1.00…

What is the most economical process for a volume of 8,000 units? b. How many units per year must be sold with each process to have annual profits of $50,000 if the selling price is $6.95 per unit? c. What is the break-even volume for each process?
Yost-Perry Industries (YPI) manufactures a mix of affordable guitars (A, B, C) that are fabricated and assembled at four different processing stations (W, X, Y, Z). The operation is a batch process with small setup times that can be considered negligible. The product information (price, weekly demand, and processing times) and process sequences are shown in Figure. Raw materials and purchased parts (shown as a per-unit consumption rate) are represented by inverted triangles. YPI is able to make and sell up to the limit of its demand per week with no penalties incurred for not meeting the full demand. Each workstation is staffed by one highly skilled worker who is dedicated to work on that workstation alone and is paid $15 per hour. The plant operates one 8-hour shift per day and operates on a 5-day work week (i.e., 40 hours of production per person per week). Overhead costs are $9,000/week. Which of the four workstations, W, X, Y, or Z, has the highest aggregate workload, and thus…
