Mgt 418 Management Information Systems (Fall 2008)

The textbook for  Fall  2008 is the same as Spring 2008: "Management Information Systems: Managing the Digital Firm", 9th edition, by Kenneth & Jane Laudon, ISBN: 0131538411.  The Laudon web site has good info.    If you think the bookstore charges too much, you can get it at Amazon from $82 - $135 or at Half.com for about $50, but it may be softbound and monochrome (the European edition).  I also have some books on reserve in the library that you can check out.  Miscellaneous class information contains various items of interest. 

Systems analysis of MWSU Parking Permit system, which is a little different than the instructions given to obtain a permit.

  Research
 -- My area of research is Operations Research (OR), which utilizes mathematical descriptions to find optimal or near-optimal solutions to management problems which may or may not be stochastic (i.e. contain some risk).  Examples include network routing, inventory management, product mix, investing, scheduling and many more -- Management Science 431 at MWSU is mostly OR! 

-- CTAP Example algorithm for 4 tasks assigned to 3 processors and the Capacitated Task Allocation Problem Set used in Lewis and Kochenberger's research on modifying Griffith and Stewart's Method of Approximation Programming for binary quadratic programs.

-- Linear Ordering of web pages based on path traversals stored in server logs.

 -- Data Files for the Linear Ordering Problem, Set Partitioning Problem, Sailor Assignment Problem as well as links to tabu search programs and problem-set creation code.

Hobbies
I often update my Photography page to highlight pictures I have recently taken.

  The Prius page!  Unfortunately, my gas mileage has dropped about 10% due to the Missouri legislature's mandate to use a blend of 10% ethanol in all Missouri gas stations.  Ethanol burns cleaner, but is less fuel-efficient.  The Prius has practically no exhaust emissions using regular gas, so using an ethanol blend that lowers gas mileage ends up costing me more with no benefit to the environment!  Advocates of bio-fuels say ethanol should not decrease gas mileage, but "should not" also means "may in fact" (decrease gas mileage), as noted in the previous article and this discussion.   In addition, the energy required to actually create and deliver the ethanol is more than the energy needed to create gasoline.  The true energy independent solution is hydrogen fuel cells using our water infrastructure and locally produced hydrogen.
