In this thesis, we study a Stochastic Disassembly Line Balancing Problem (SDLBP) with hazardous tasks. We define success and failure events for each hazardous task and describe several scenarios over all hazardous tasks. Our aim is to maximize expected profit over all scenarios. We construct mathematical model with one, two and three hazardous tasks. Then, general formulation both in nonlinear and linear form is studied. We test the performance of the model on randomly generated data using the networks taken from the literature. Moreover, we study the Value of Stochastic Solution (VSS) which is the added value of considering uncertainty in a decision. The limits of the SDLBP models are observed by the increase of number of tasks in a network and by the increase in number of hazardous tasks. We propose some solution approaches and bounding procedures, and show their satisfactory performances

A disassembly line balancing problem with fixed number of workstations Kalaycilar, Eda Goksoy; Azizoğlu, Meral; Yeralan, Sencer (2016-03-01) In this study, a Disassembly Line Balancing Problem with a fixed number of workstations is considered. The product to be disassembled comprises various components, which are referred to as its parts. There is a specified finite supply of the product to be disassembled and specified minimum release quantities (possible zero) for each part of the product. All units of the product are identical, however different parts can be released from different units of the product. There is a finite number of identical w...
Disassembly line balancing with limited supply and subassembly availability Altekin, FT; Kandiller, L; Özdemirel, Nur Evin (2003-10-30) Disassembly line balancing problem (DLBP) aims at finding a feasible assignment of disassembly tasks to workstations such that precedence relations among tasks are satisfied and some measure of effectiveness is optimized. We consider partial disassembly under limited supply of a single product as well as availability of its subassemblies. Hence, in satisfying the demand for revenue generating parts, both discarded products and available subassemblies can be utilized. We assume that part revenues and demand,...
Design and implementation of a mems based spiral channel dielectrophoretic separator for cytometry applications Yılmaz, Gürkan; Külah, Haluk; Department of Electrical and Electronics Engineering (2010) This thesis reports design and implementation of a MEMS based spiral channel dielectrophoretic separator for cytometry applications. Main objective of the thesis is to separate leukemia cells from healthy leukocytes with respect to the differences in their dielectric properties. A novel MEMS based dielectrophoretic separator with spiral channels and concentric 3D electrodes has been proposed. The proposed geometry decreased the footprint, which reduces the device cost, without degrading the separation and q...
A Multi-mode project scheduling problem with a single nonrenewable resource Altıntaş, Cansu; Azizoğlu, Meral; Department of Industrial Engineering (2017) In this thesis, we consider a multi-mode project scheduling problem with a single nonrenewable resource. We assume that the resource is released in pre-specified times at pre-specified quantities and the resource is consumed at activity completions. The activities can be processed at different modes where a mode is defined by a processing time and a resource requirement amount. Our problem is to select the modes and timings of the activities so as to minimize the project completion time. We develop a mixed ...
A stochastic programming approach for the disassembly line balancing with hazardous task failures Kalaycilar, Eda Goksoy; Batun, Sakine; Azizoğlu, Meral (2021-04-01) We consider a partial disassembly line balancing problem with hazardous tasks whose successful completions are uncertain. When any hazardous task fails, it causes damages of the tasks on the workstation that it is performed on and all remaining tasks to be performed in the succeeding workstations. We attribute probabilities for the successful completion and failure of the hazardous tasks and aim to maximise the total expected net revenue. We formulate the problem as a two-stage stochastic mixed-integer prog...
