Question

Data Screen Corporation is a highly automated manufacturing firm. The vice president of finance has decided that traditional standards are inappropriate for performance measures in an automated environment. Labor is insignificant in terms of the total cost of production and tends to be fixed, material quality is considered more important than minimizing material cost. and customer satisfaction is the number one priority. As a result. production and delivery performance measures have been chosen to evaluate performance. The following information is considered typical of the time involved to complete and ship orders.
Waiting time:
From order being placed to start of production.
8.0 days
From start of production to completion
7.0 days
Inspection time
1.5 days
Processing time
3.0 days
Move time
2.5 days
Required:
1. Calculate the manufacturing cycle efficiency.
2. Calculate the delivery cycle time.

Answer 1

Answer:

Answer:

1. MCE = 21.42%

2. Delivery Cycle Time 22 days

Explanation:

The Manufacturing Cycle Time is given by the formula:

Manufacturing cycle time = Inspection Time + Process Time + Move Time + Queue time

Here we have

Inspection time =1.5 days

Processing time =3.0 days

Move time =2.5 days

Queue time= 7.0 days

Wait time= 8.0 days

Manufacturing Cycle  Time = 1.5+3.0+2.5+ 7.0=  14.0 days

MCE= Manufacturing Cycle Efficiency Time= Process Time/ Processing Time + Inspection Time + Move Time + Queue time

MCE = 3/ 14=0.2142= 21.42%  

It means that MCE  consists of 21.42 %actual processing and 79 % consists of non value added activities.

2.  Delivery Cycle Time= Manufacturing Cycle  Time + Wait time

Delivery Cycle Time= 14.0 days + 8.0 days= 22.0 days

The difference between wait time and queue time is that wait time is the time when the customer places an order until it is delivered.And queue time from the start of the production of the order.
