Question

A manufacturing cell is set up to make a left and ]required at an assembly station. these are two distinct manufacturing processes. after the manufacturing is complete, the left and ]s are assembled as a pair at the station. the assembly station (needing both a left and ]) has a daily demand of 1600 assemblies and operates in a single 7.5-hour shift.

a. what should be the takt time for the manufacturing cell assuming both brackets must be produced for every assembly? provide the answer in terms of (i) number of total brackets and (ii) number of containers (having both brackets) that need to be produced.

Answer 1

Takt time: 0.28 minutes/assembly or 16.88 seconds/assembly

(i) Total brackets needed: 3200

(ii) Containers needed: 1600

Takt Time and Production Requirements for the Manufacturing Cell

a. Takt Time:

Calculate takt time in minutes:

Daily demand = 1600 assemblies

Shift duration = 7.5 hours

Takt time (minutes) = (Shift duration in minutes) / Daily demand = (7.5 hours * 60 minutes/hour) / 1600 assemblies = 0.28 minutes/assembly

Takt time in seconds:

Takt time (seconds) = Takt time (minutes) * 60 seconds/minute = 0.28 minutes/assembly * 60 seconds/minute = 16.88 seconds/assembly

b. Production Requirements:

Total Brackets:

Each assembly requires one left bracket and one right bracket.

Therefore, the total number of brackets needed per day is twice the daily demand of assemblies.

Total brackets = 2 * Daily demand = 2 * 1600 assemblies = 3200 brackets

Containers Needed:

Each container holds one assembled pair of brackets (left and right).

Since the daily demand is for 1600 assemblies, the same number of containers are needed.

Containers needed = Daily demand = 1600 assemblies
