Consider an assembly line such as the burrito assembly line at Chipotle Mexican Grill. During slow times of the day, one server can handle assembly, but during very busy times, having many servers would be prudent. Explain why either approach wouldn’t work all the time, and the benefit ofmatching the number of servers to the pace of customer arrivals.
Dr. Lori Baker, operations manager at Nesa Electronics, prides herself on excellent assembly line balancing. She has been told that the firm needs to complete 96 instruments per 24-hour day. The assembly-line tasks for the production of the instrument are:

If the daily production (24-hour) production rate is 96 units, what is the highest allowable cycle time?
If the cycle time after allowances is given as 12 minutes, what is the daily (24-hour) production rate?
With a 12-minute cycle time, what is the theoretical minimum number of stations with which the line can be balanced?
Assign task to workstations. Use the following decision rules (heuristics): longest task first, break ties by assigning the task with the most followers.
What are the efficiency and the balance delay of the assembly line?

Calculate the average time required to produce one piece per hour if there are five
machines with 0.6 h machining time per piece, 0.15 h machine servicing time per piece
and 0.1 h per machine per hour machine downtime average. Each machine is available
for production 0.8 h each hour.

- 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 motors have been delivered and are available for processing. The motors will be repaired at two workstations in the following manner. Workstation 1: Dismantle the motor and clean the parts. Workstation 2: Replace the parts as necessary, test the motor, and make adjustments. The customer’s shop will be inoperable until all the motors have been repaired, so the plant manager is interested in developing a schedule that minimizes the makespan and has authorized around-the-clock operations until the motors have been repaired. The estimated time to repair each motor is shown in the following table: TIME (HR) Motor Workstation 1 Workstation 2 M1 M2 M3 M4 M5 12 4 5 15 10 22 5 3 16 8arrow_forwardAn assembly line for inkjet printers is composed of 8 persons performing different tasks.

- ABC Solutions is a traditional company in a textile industry with a combined workforce of 150 staff. Due to increased levels of competition, this company is now increasingly finding it difficult to compete – especially as the larger companies seem to be a little more innovative, agile and responsive to client requirements. Management have noticed that staff, especially the highly skilled ones, are now leaving the company to seek work elsewhere (in these larger companies). This has meant appointing new staff and undertaking a considerable amount of re-training to replace those that have left the company. Apart from impacting on core business operations, ABC Solutions has started witnessing a drop in its profit margin. Given this position, senior management at ABC Solutions have decided to implement a performance measurement tool (PMT) that would allow them to align the strategic, management and operational requirements of the business. They are therefore considering the adoption of the…arrow_forwardYou have just determined the actual number of workstations that will be used on an assembly line to be 6 using the assembly-line balancing procedure.
