Abstract

Both desirable (good) and undesirable (bad) outputs and inputs may be present. For example, the number of defective products is an undesirable output. One wants to reduce the number of defects to improve the performance. If inefficiency exists in production processes where final products are manufactured with a production of wastes and pollutants, the outputs of wastes and pollutants are undesirable and should be reduced to improve the performance.
