Time Dependent Production Models

Posted on July 28, 2021 by Abigail Stason

The engineer of a concrete products plant is scheduling production of a certain size concrete pipe over the next 5 months. No pipe is on hand at the beginning of the first month. The engineer wants to meet the projected demand over the 5-month period at minimum cost. Constraints are imposed on the monthly regular rate processing time and the amount of raw materials available each month, as shown in the table below:

  Jul Aug Sep Oct Nov Dec
Pipe Required (Number of 20 foot stands) 20 30 40 20 40 30
Cost of labor during regular time $/hr $15 $15 $15 $18 $18 $18
Cost of labor during overtime $/hr $17 $17 $17 $20 $20 $20
Labor available (persons) 30 30 40 40 20 20
Material available (stands) 40 50 50 10 30 20

It takes 75 hours to produce one stand of pipe, and $20 to store one stand of pipe for one month.

  1. a)Assume that no materials can be carried over from month to month.
  2. b)Assume that materials can be carried over from month to month at no cost.
