c) If the cycle time after allowances is given as minutes, what is the daily (-hour) production rate?

The daily production rate = units per day (round your response to two decimal places).

d) With a 10 minute cycle time, what is the theoretical minimum number of stations with which the line can be balanced?

The theoretical minimum number of workstations is the total task-duration time (the time it takes to make the product) divided by the cycle time. Fractions are rounded to the next higher whole number:

where n is the number of assembly tasks.

For the given activities, the total operational time = minutes (enter your response as a whole number).

The theoretical minimum number of workstations = (round your response to the immediate higher whole number).

e) Using the longest assigned task time of all of the workstations and six workstations, what is the operating efficiency?

Using the longest assigned task time of all of the workstations and 6 workstations, the operating efficiency of the assembly line = (enter your response as a percentage rounded to two decimal places).

f) What is the total idle time per cycle with a 10 minute cycle time and 6 workstations?

The idle time for the assembly line per cycle = minutes (enter your response as a whole number).

g) What is the best work station assignment you can make without exceeding a 10 minute cycle time and what is its efficiency?

Assignment of tasks to workstations can be done by using an assignment heuristic like longest task time and following the guidelines outlined below:

1. Task time across all jobs assigned to a workstation should be

2. Task's precedence requirements should be satisfied

3. (Cycle Time - Workstations Operational Time) should be minimized

4. New workstation, assign longest time activity available first whose precedence requirements are satisfied

5. A task can only be assigned to one workstation

The correct precedence relationship with one of the possible assignment of tasks to workstations for the given 10 minute cycle time is shown in

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 120 instruments per 24-hour day. The assembly-line activities are: Performance Time (mins) Task A B C D E F This exercise only contains parts b, c, d, e, f, and g. b) For the given daily (24-hour) production rate of 120 units, the highest allowable cycle time = 6 8 7 3 5 Predecessors A A, B B Task G H 1 J K Performance Time (mins) 5 7 1 8 2 minutes (enter your response as a whole number).
