Question

An 18-station transfer line has an ideal cycle time of 0.70 min, an average downtime of 7.0 min per line stop occurrence, and a station failure frequency of 0.02 for all stations. A proposal has been submitted to locate a storage buffer between stations 9 and 10 to improve line efficiency. Determine the current line efficiency and production rate, and

Answer 1

The current line efficiency is 9.09% and the production rate is 0.13 units per minute.

Step-by-step explanation:

The current line efficiency can be calculated using the formula:

Line Efficiency = Cycle Time / (Cycle Time + Average Downtime)

Given the values, the current line efficiency is:

Line Efficiency = 0.70 / (0.70 + 7.0) = 0.70 / 7.70 = 0.0909 or 9.09%

The production rate can be calculated using the formula:

Production Rate = 1 / (Cycle Time + Average Downtime)

Given the values, the current production rate is:

Production Rate = 1 / (0.70 + 7.0) = 1 / 7.70 = 0.1299 or 0.13 units per minute
