| The subject of the present research is to investigate, model and solve the problems of Lot Sizing and Distribution Inventory Management when the available data is given in the form of fuzzy numbers. Subject to a variety of assumptions, main contribution of this thesis is included in Chapters 3 to 5.; Chapters 1 and 2 provide introduction and literature survey, respectively, related to the problems considered in the thesis. Chapter 3 deals with the distribution inventory management problem with variable demand rate and both without and with backorders, under fuzzy information. Similarly, Chapters 4 and 5 consider the lot sizing inventory problem under variable demand rate and both without and with backorders, respectively, under fuzzy information with a finite planning horizon. Finally, the conclusion and the discussion on the contributions made in the thesis, along with some recommendations for further research, are given in Chapter 6. |
