A job was timed for 60 cycles and had an average of 1.2 minutes per piece. The performance rating was 95%, and workday allowances are 10 percent. Determine each of the following:

a. Observed time.
b. Normal time.
c. Standard time.

Respuesta :

Answer and Explanation:

The computation is shown below:

a) Observation time is

= Average time

= 1.2 minutes

b)  The Normal time is

= Observation time × performance rating

= 1.2 minutes × 0.95

= 1.14 minutes

3. The standard time is

= normal time × Allowance factor

where,

Normal time is 1.14 minutes

And, the Allowance factor is

= 1 ÷ (1- A)

= 1 ÷ (1- 0.1)

= 1.11

So, the standard time is  

= 1.14 × 1.11

= 1.265 minutes.
