Numerical results and comparison with fixed cycle

Numerical results and comparison with fixed cycle 

In the examples we will consider in this section, we want to maximise the profit. The elements we consider in this arbitrary profit function P, are the average delivery times Si for the various types and the set-up rates, m.- = X.iP,o, for the various types  

In order to maximise this profit, we will try different sets of [x, ..,xu), for instance starting with increasing the x for the types with the smallest X or decreasing the x for the types with the largest X. 

We will compare this production model with the extended gating cyclic service model that has been described in Subsection 3.2.1. In a production cycle we have a fixed time Ti available for the production of type i including one set-up. Sometimes this time may not be used entirely, but at other times the time will not be enough to produce all orders, leading to orders that have to wait until the next cycle. By means of iteration, we can determine the optimal values for and the 

Now we will compare the results of the decomposition method, with normal extended service and with extra extended service, with the fixed cycle. For two different examples we will determine the set of values Xgp, with the highest profit. We will compare the profit with the maximum profit for the fixed cycle production rule.
