Description

Describe the difference between using linear programming spreadsheets and the generation of a computer program using a high-level computer language to obtain decision-making information. Post an example of each. Which do you feel is more effective? Why?

When responding to your classmates, discuss if you agree with their assessment of the effectiveness of spreadsheets versus a computer program. Cite examples, if possible, to support your argument.

Refer to the Module Three Discussion Rubric for directions on completing these discussions.

3-1 Discussion: LP vs. Computer Programming Caitlin Smith posted Aug 1, 2018 6:56 PM During my undergraduate time, I took two courses on computer programming and one on data analytics. I learned how to program with C++ and Fortran (very surface level and I probably couldn't do it anymore) and how to interpret the data that is collected through computer programming. However, with that previous experience, it makes me appreciate the user friendliness of linear programming in Excel. I would spend hours putting together computer programs for homework assignments that I could never get to work exactly the way I imagined they should but in 30 minutes I can put together a spreadsheet with numeric outputs and get correct answers. There are obviously limitations to linear programming with Excel that you don't face with in depth computer programming but generally linear programming is more applicable for every day use and can easily be explained to others who may not have much programming experience. Using solver in Excel is great with input values that are known and the ability to insert constraints in terms of these known variables. Computer programming would be a much better use if there are hundreds of thousands of variables, known and unknown, and dozens of constrains that could possibly change based on the variables; but that would be better left to someone who has an background specifically in computer programming. As someone majoring in project management, I think that knowing and understanding linear programming in Excel will be much more useful for me. When I'm managing large projects for companies, I won't be interested in spending days and weeks trying to put together a computer program when I could have used Excel, spending more time managing my project team and making sure we are completing tasks on time. Included is an example of linear programming from Montana State University and a webpage with very introductory computer programs using C language from Programming Simplified. • References: Montana Sate University example: https://www.msubillings.edu/asc/resources/math/tutorials/finitemathhelps/Lin%20Pr og%20with%20Excel.pdf Computer Programming examples: https://www.programmingsimplified.com/c-programexamples Lin Prog with Excel.pdf (169.17 KB) 3-1 Discussion Ebenezer Marfo posted Jul 31, 2018 11:59 PM Subscribe This page automatically marks posts as read as you scroll. Adjust automatic marking as read setting A linear program consists of a set of variables, a linear objective function indicating the contribution of each variable to the desired outcome, and a set of linear constraints des cribing the limits on the values of the variables. The “answer” to a linear program is a set of values for the problem variables that results in the best — largest or smallest — value of the objective function and yet is consistent with all the constraints. Once a problem has been formulated as a linear program, a computer program can be used to solve the problem. In this regard, solving a linear program is relatively easy (faculty.washington.edu). Example: A high-level language is a programming language that uses English and mathematical symbols, like +, -, % and many others, in its instructions. When using the term 'programming languages,' most people are actually referring to high-level languages. High-level languages are the languages most often used by programmers to write programs (Zandbergen, n.d.). Examples of high-level languages are C++, Fortran, Java and Python. To get a flavor of what a high-level language actually looks like, consider an ATM machine where someone wants to make a withdrawal of $100. This amount needs to be compared to the account balance to make sure there are enough funds. The instruction in a high-level computer language would look something like this: x = 100 if balance x: print 'Insufficient balance' else: print 'Please take your money' This is not exactly how real people communicate, but it is much easier to follow than a series of 1s and 0s in binary code (Zandbergen, n.d.).
