Analysis of a Simple Debugging Model

نویسنده

چکیده

A system has an unknown number of faults. Each fault causes a failure of the system, and is then located and removed. The failure times are independent exponential random variables with common mean. A Bayesian analysis of this model is presented, with emphasis on the situation where vague prior knowledge is represented by limiting, improper, prior forms. This provides a test for reliability growth, estimates of the number of faults, an evaluation of current system reliability, and a prediction of the time to full debugging. Three examples are given.

Hitting the Wall: Errors in Developing and Debugging a "Simple" Spreadsheet Model

Undergraduate MS business students developed and debugged a spreadsheet modelfrom a wordproblem. This model consisted ofa bid to build a wall. The problem was designed to be relatively simple and domain-free, to address the concern that past spreadsheet experiments mqv have usedproblems that were too dtflcult or that required domain knowledge that subjects did not have. During the development p...
