Molitemo, C. H. C. Usage of the Para consistent Logic in the elaboration of the synthesis of evaluation questionnaire case of university degree. Dissertation (Master's in Production Engineering) Program of Post-Graduation in Production Engineering, Universidade Paulista, 2009. Key words: Paraconsistent Logic, Production Engineering, Didactic Process, Decision Support System, Contradictory Evaluation. Some Areas of Industrial Engineering, including, among others, Quality Management, Economic Management, Decision Support Systems and Performance Evaluation (including Personnel Performance Evaluation, Teaching Performance Evaluation and Learning Performance Evaluation, among other modalities) do have common aspects that set them apart of all other areas of Industrial Engineering, because they deal with hazy observables (viz.: not quite well-established "facts", which are the subject of controverse or non­universally-consensual methods of measurement), and thus are a fertile ground for the development of new paradigms of measurement, especially those which main tenet is the recognition and incorporation of uncertainty, complexity and credibility as intrinsics, not (fully, at least) separable from the actual measurement. Arising from such context, the present work describes a novel method for the evaluation of hazy observables, particularly those gauged by means of questionnaires (which are usually biased, in that they have ample space for subjective interpretations). The method presented herein employs specially constructed questionnaires which have to be responded with degrees of favorable ( or unfavorable) evidence, that are then applied in various different scenarios and, after analysis, lend themselves to the creation of an integralizing graph which four possible regions may be interpreted to represent inconsistency, indetermination, unsatisfying and satisfying, respectively, being then used to characterize, at first each question, then the whole information gauged by the questionnaire, leading to the creation of a unified ( decision, management or performance) index, that embodies the acquired information. To illustrate the application of this novel method, a Teaching Performance Evaluation, by the students, of a single discipline (as taught by a single educator during one semester) was undertaken as case­study, and, besides providing an integralized evaluation index, it revealed a subjective relationship between evaluator and evaluate, in that students having worse grades evaluate badly their instructor, and vice-versa.
