Further information on Simulation of Queues (external links)

1. Monte Carlo Simulation of Queues - A site on Operations Research Topics - this link goes to the topic on Queues simulation but you can navigate to the main page. Prepared by J.E. Beasleyof the Imperial College in the UK

 

Further information on Goal Programming (external links)

1. Goal Programming Slides (Power Point presentation: may take long to download 3.5 MB) - has a worked example on solving two variables goal programming models. Prepared by Asst. Prof. John S. Loucks located at St. Edwards University.

 

Further Information on Excel Solver (external links):

1. Installing and Using Solver - the information is on an older edition of solver than what you'll be using, but the dialog boxes looks mostly the same. Just two notes -

  1. If you are in the Solver dialog, and you click Options, you should ensure that the boxes mark "assume linear model" and "assume non-negative" are ticked

  2. When multiplying the "changing cells" (i.e. the objective variables) with that of the coefficients of the constraints to get a formula for the constraint ... you can use the SUMPRODUCT function of Excel if these values are in an array i.e. SUMPRODUCT(B3:B5, D3:D5).

2. Understanding Solver Reports - information on understanding solver reports can be found here
