Z-number, Introduction and Engineering Applications

The reliability and probability theory have been integrated in a word computing sense within Z-number by L.A. Zadeh. The novelty of his idea could be used in various ranges of engineering applications. Project management is one of the important and vital part of each project. As in the real world problem project manager should interact with their employees using natural language is better than using crisp mathematics formula. In this study critical path method(CPM) is improved by incorporating Z-number to satisfy the above mentioned need. With incorporating Z-number the most real world language communication should be used in the real project management. To show the applicability and superiority of proposed method its outcome has been compared with the crisp and fuzzy numbers.
