Analysis of a deterministic demand production/inventory system under nonstationary supply uncertainty
Gullu, R; Onol, E; Erkip, N (Informa UK Limited, 1997-08-01)
In this article we investigate a periodic review inventory model under deterministic dynamic demand and supply unavailability. In a given period, supply is either available or completely unavailable with given probabilities. Supply unavailability probabilities are nonstationary over time. We show the optimality of an order-up-to level policy, and obtain a newsboy-like formula that determines the optimal order-up-to levels. Our formula would provide guidence as to the appropriate amount of inventory to stock...
Solution approaches for flexible job shop scheduling problems
Balcı, Şerife Aytuğ; Azizoğlu, Meral; Oğuzsoy, Cemal Berk; Department of Industrial Engineering (2013)
In this thesis, we consider a flexible job shop scheduling problem existing in discrete parts manufacturing industries. We are motivated by the production environment of Roketsan Missiles Industries Incorporation, operating at Turkish defense industry. Our objective is to minimize the total weighted completion times of the jobs in the system. We formulate the problem as a mixed integer linear program and find that our model could find optimal solutions only to small sized problem instances. For medium and l...
Flexible assembly line design problem with fixed number of workstations
Barutçuoğlu, Şirin; Azizoğlu, Meral; Department of Industrial Engineering (2009)
In this thesis, we study a Flexible Assembly Line Design problem. We assume the task times and equipment costs are correlated in the sense that for all tasks the cheaper equipment gives no smaller task time. Given the cycle time and number of workstations we aim to find the assignment of tasks and equipments to the workstations that minimizes the total equipment cost. We study a special case of the problem with identical task times. For the general case, we develop a branch and bound algorithm that uses pow...
