Analyses of serial production lines and assembly systems for throughput and inyerdeparture time variability
(Bilkent University, 1998)In this thesis, we study three different but closely related production system design problems. First, we investigate the effects of various design factors such as number of stations, buffer capacity, allocation of bulfers ... -
Analysis of a hospital call center
(Bilkent University, 2012)In this thesis, we study the call center operations of a particular hospital located in Ankara, namely Güven Hospital. The hospital call center takes role as a medical consulting and appointment center and also domestic ... -
An analysis of order review
(Bilkent University, 1995)Order Review/Release (ORR) activities have mostly been ignored in past job shop research. In the majority of these studies, arriving jobs are immediately released to the shop floor without considering any information ... -
Analysis of scheduling problems in dynamic and stochastic FMS environment : comparison of rescheduling polices
(Bilkent University, 2001)In this thesis, we study the reactive scheduling problems in a dynamic and stochastic flexible manufacturing environment. Specifically, we test different scheduling policies (how-to-schedule and when-to-schedule policies) ... -
Analysis of variance reduction techniques in various systems
(Bilkent University, 2003)In this thesis, we consider four different Variance Reduction Techniques (VRTs): Antithetic Variates (AV), Latin Hypercube Sampling (LHS), Control Variates (CV), and Poststratified Sampling (PS). These methods individually ... -
Ant colony optimization for the single model U-type assembly line balancing problem
(Bilkent University, 2004)The assembly line is a production line in which units move continuously through a sequence of stations. The assembly line balancing problem is the allocation of tasks to an ordered sequence of stations subject to the ... -
Artificial neural networks modeling and simulation of the in-vitro nanoparticles - cell interactions
(Bilkent University, 2012)In this research a prediction model for cellular uptake efficiency of nanoparticles (NPs), which is the rate of NPs adhered to the cell surface or entered into the cell, is investigated via Artificial Neural Network (ANN) ... -
Assembly line balancing using genetic algorithms
(Bilkent University, 1997)For the last few decades, the genetic algorithms (GAs) have been used as a kind of heuristic in many areas of manufacturing. Facility layout, scheduling, process planning, and assembly line balancing are some of the areas ... -
Auction based scheduling for distributed systems
(Bilkent University, 2005)Businesses deal with huge databases over a geographically distributed supply network. When this is combined with scheduling and planning needs, it becomes too difficult to handle. Recently, Fast Consumer Goods sector ... -
Balancing straight and U-Type assembly lines with stochastic process times
(Bilkent University, 2003)In this thesis, we study the problem of assembly line balancing with stochastic task process times. The research considers both the well-known straight line balancing problem and U-line balancing problem where the line ... -
Beam search algorithms for the mixed-model assembly line sequencing problem
(Bilkent University, 2005)In this thesis, we study the mixed-model assembly line sequencing problem that considers the following objectives: 1) leveling the part usage, and 2) leveling workload on the final assembly line. We propose Beam Search ... -
The behavior of transient period of nonterminating simulations: an experimental analysis
(Bilkent University, 2001)The design and control of many industrial and service systems require the analysts to account for uncertainty. Computer simulation is a frequently used technique for analyzing uncertain (or stochastic) systems. One ... -
Distributed scheduling
(Bilkent University, 1999)Distributed Scheduling (DS) is a new paradigm that enables the local decisionmakers make their own schedules by considering local objectives and constraints within the boundaries and the overall objective of the whole ... -
Evaluation of ammunition and fuel supply systems of a Turkish armored battalion during mobilization and deployment using simulation
(Bilkent University, 2002)In current wars, supply systems have become vital factors to reach military success. With improvements in technology, the capabilities and means of military units have also improved and as a result, the supply materials ... -
Evaluation of army corps food supply system using simulation
(Bilkent University, 2002)Food Supply System is one of the main elements of Army Logistics System. The ultimate objective in food supply system is to provide the food at the right time and at the right place. If this objective is achieved, the ... -
Evaluation of mobilization and deployment plan of a Turkish armored battalion via simulation
(Bilkent University, 2001)As being ready for war as soon as possible and with minimum casualties during the crises is the first mission for the troops, the Mobilization and Deployment Plan arises as one of the most important topic for Army. Because ... -
Flowtime estimation in dynamic job shops
(Bilkent University, 1996)In the scheduling literature, estimation of job flowtimes has always been an important issue since the late sixties. The previous studies focus on the problem in the context of due date assignment and develop methods ... -
Generating robust and stable machine schedules from a proactive standpoint
(Bilkent University, 2009)In practice, scheduling systems are subject to considerable uncertainty in highly dynamic operating environments. The ability to cope with uncertainty in the scheduling process is becoming an increasingly important issue. ... -
Inquiring the main assumption of the assembly line balancing problem : solution procedures using and/or graph
(Bilkent University, 2005)In this thesis, we consider the assembly/disassembly line balancing (ADLB) problem. The studies in the literature consider assembly and disassembly problems separately and use task precedence diagram (TPD) and AND/OR ... -
Integration of production, transportation and inventory decisions in supply chains
(Bilkent University, 2012)This dissertation studies the integration of production, transportation and inventory decisions in supply chains, while utilizing the same vehicles in the inbound and outbound. The details of integration is studied in ...
