Inventories can be an important competitive weapon and are a major control problem in many companies, and improper lot sizes can affect the inventory levels and the costs associated with them. In the present thesis, we formulate and analyze such a problem and its variations under both crisp and fuzzy environments with a variety of assumptions. Specifically, we model such a problem with imprecise variable demand and imprecise total cost that includes setup, backordering and holding costs, as zero-one integer linear program. Also, the problem is modeled as piece wise integer linear program by incorporating quantity discounts. Furthermore, we consider such a problem, with ambiguous variable demand to be satisfied as closely as possible. Therefore we use goal-programming approach to solve such a problem. The present thesis seeks to provide an alternate, easy to understand and hopefully improved means of obtaining optimal lot sizing solution. The thesis demonstrates the adaptability of the approaches used, for decision making in a variety of applications, particularly scheduling purchases and production. The methods presented in this thesis are computationally effective and beneficial for determining the optima solution for inventory lot sizing problems. en_US dc.format.extent 4977672 bytes dc.format.extent 184 bytes dc.format.mimetype application/pdf dc.format.mimetype text/plain dc.language en en_US dc.language.iso en_US dc.rights info:eu-repo/semantics/openAccess dc.title Analysis of inventory lot size problem en_US dc.type info:eu-repo/semantics/masterThesis dc.type master thesis en_US dc.degree.discipline Mechanical & Manufacturing Engineering en_US dc.degree.level Master of Science (M.Sc.) en_US
