The Temporary-Ordered Routing Algorithm (TORA) – An Operations Research Software

TORA is an algorithm i.e. a mathematical set of instructions or programs (mathematical-software). It is an optimization system in the area of operations research which is very easy to use. Further, TORA is menu-driven and Windows-based which makes it very user friendly.

The software has in-built tutorial for the novice and it also produces animated graphical linear programming solution. The other features of the software include dynamic construction of ‘Critical Path Method’ charts and creation of search-trees to name some.

The software can be executed in automated or tutorial mode. The automated mode reports the final solution of the problem, usually in the standard format followed in commercial packages, while the tutorial mode keeps on giving step-wise information about the methodology and solution.

TORA also offers self-paced learning of all the computational algorithms in a manner that allows students to check their understanding of the material with immediate detailed feedback from the software. It enables the instructors to demonstrate ideas that otherwise are literally impossible to present.

The various Models in Operations Research which can be solved using the Temporary-Ordered Routing Algorithm include Linear Programming Graphical,  LPP: Transportation Models, Integer Programming, Queuing Models, CPM/PERT, Game Theory, Matrix Inversion, Simultaneous Linear Equations etc. The functionality tools in the ‘Temporary-Ordered Routing Algorithm’ feature a schema browser, SQL worksheet, PL/SQL editor & debugger, storage manager, rollback segment monitor, instance manager, and SQL output viewer.

    This will help us..But we needed descriptive notes on —
    1. TQM Principles,
    2. Quality Improvement Techniques,
    3. TQM Tools,
    4. Concept of Six Sigma,
    5. Quality Circles.
    6. SPC.

    to the earliest….as our exams r rushing…

  2. says

    @ Chetan,

    i ll try and post these … for the SPC part you will have to refer some book, for, it has lot of control charts in it with numerical treatment… i would suggest LC Jhamb’s (Everest Publ.) Quantitative Techniques for the same.

    please provide me the solution to the following problem on probability A bank has a test designed to establish the credit rating of a loan application. If the persons, who default (D), 90% fail the test (F). Of the persons, who will repay the bank (ND), 5 % fail the test. Furthermore, it is given that 4% of the population is not worthy of credit (i.e. defaulters). Given that someone failed the test, what is the probability that he actually will default (When given the loan)?

    Could you please send me the free download link for TORA? I have been trying to procure one but I could not succeed in my attempts. You are the one and the only person who could guide me in this endeavour. Please help me. Thanks a million.

    @ Dr. Venkatkrishnan

    As you can read through prof Saisree’s comment above… its not a free package. For the academic purpose,there is a students limited edition though; which you might get along-with few of text-books… one of them I know of is “Operations Research” by “TAHA”..

        Dear Sir:

        Will you be able to share with me the other possible softwares that can solve Operations Research problems?

        Also, can you suggest some Indian journals where I can publish papers in management without much time delay?
