Question

As operations manager, you are concerned about being able to meet sales requirements in the coming months. You have just been given the following production report: JAN FEB MAR APR Units produced 2,250 1,750 2,750 2,950 Hours per machine 318 194 393 315 Number of machines 5 7 6 5 Find the average of the monthly productivity figures (units per machine hour).

Answer 1

Answer: 2.81 per hour

Explanation:

Average monthly productivity = (January productivity + February productivity + March productivity + April productivity) / 4

January productivity:

= Units produced / ( Hours per machine * Number of machines )

=  2,250 / ( 318 * 2 )

= 3.537

February productivity:

= 1,750/ ( 194 * 4 )

= 2.255

March productivity:

= 2,750 / ( 393 * 3 )

= 2.332

April productivity:

= 2,950/ ( 315 * 3)

= 3.121

Average monthly productivity = (3.537 + 2.255 + 2.332 + 3.121)/ 4

 = 2.81 per hour
