Problem in Schedulling Machines and operations

Problem in Schedulling Machines and operations

Problem in Schedulling Machines and operations

(OP)
I need to solve a problem using Integer Programming.
The Problem is a factory with n Operations and m Machines. There are pij times of processing (for operation i and machine j), and every operation can be done in every machine. This is a case of parallel machines

There are precedence relationships within the operations, and one machine only can done one operation at the same time.
Its important to say that there is a planning horizon of H units of time.

The objective is to reduce the necessary time to make all the operations.

Can you help me?

RE: Problem in Schedulling Machines and operations

Are all the machines equal?  That is, does every machine produce the same number of parts in the same time?  Are  their any operators (people running machines)in this exercise?   

Don't you start by defining the required operations and the time required for each?  

Are you calculating for a flow of parts or a single part?

Have you read The Goal by Goldratt?
