Concept explainers
Sunshine House received a contract this year as a supplier of Girl Scout cookies. Sunshine currently has five production lines, each of which will be dedicated to a particular kind of cookie. The production lines differ by sophistication of machines, site, and experience of personnel. Given the following estimates of processing times (in hours), assign cookies to lines to minimize the sum of completion times:

- K 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.

It had one line dedicated to the manufacture of light-duty vent hood shells, but because of strong demand it recently added a second line. The new line makes use of higher-capacity automated equipment but consists of the same basic four processes as the old line. In addition, the new line makes use of one machine per workstation, while the old line has parallel machines at the workstations. The processes, along with their machine rates, number of machines per station, and average times for a lone job to go through a station (i.e., not including queue time), are given for each line in the following table: Process Old Line New Line Rate per Machine (parts/hour) # Machines per Station Time (minute) Rate per Machine (parts/hour) # Machines per Station Time (minute) Punching 15 4 4.0 120 1 0.50 Braking 12 4 5.0 120 1 0.50 Assembly 20 2 3.0 125…arrow_forwardTailwind, Inc., produces high-quality but expensive training shoes for runners. The Tailwind shoe, which sells for $210, contains both gas- and liquid-filled compartments to provide more stability 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.

- Manufacturing Company uses FIFO method of accumulating costs in a two-department process. Materials are introduced at the inception of the process except for a special material which is added in department 2 at 60% completion as to overhead. Inspection is done at the end of the process in both departments. Production data for Department 2 are given below: In process, beginning, (80% labor, 70% overhead)2,000 Transferred in 14,900 In process, ending (40% labor, 20% overhead) 3,000 Normal spoilage 200 Abnormal spoilage (found at 30% completion as to laborand 15% as to overhead due to internal failure) 400 Cost data for the month:In process beginning:Transferred in 15,020 Special materials 1,900 Direct labor 4,388 Overhead 11,044 Current costs:Transferred in 137,080 Special materials 14,030 Direct labor 46,000 Overhead 113,564 The cost of units transferred to finished goods is?The cost of spoilage charged to revenue is?arrow_forwardA local 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.
