Modeling and analysis of customer requirements from a driver’s seat

Çabuk, Vuslat
In vehicles one of the most important components which affect comfort of the driver and the purchasing decision is the driver’s seat. In order to improve design of a driver seat in a leader company of automotive sector, a comprehensive analysis of customer expectations from the driver seat is performed with a cross functional team formed by representatives of design, marketing, production, quality and services departments. In this study, collection of customer voice data and development of an exceptional “customer satisfaction estimation model” using these data are presented. Data are modeled by the help of Logistic Regression. This model is able to estimate how much a given customer is likely to be satisfied with the driver seat at a certain confidence level. It is also explained how this model can be used to identify design improvement opportunities that help increase the probability that a customer likes the driver seat. The modeling and analysis approach used for the particular case is applicable in general to many other cases of product improvement or development.


Approximate models and solution approaches for the vehicle routing problem with multiple use of vehicles and time windows
Boer, Jeroen Wouter de; Süral, Haldun; Department of Industrial Engineering (2008)
In this study we discuss the Vehicle Routing Problem with multiple use of vehicles (VRPM). In this variant of the routing problem the vehicles may replenish at any time at the depot. We present a detailed review of existing literature and propose two mathematical models to solve the VRPM. For these two models and their several variants we provide computational results based on the test problems taken from the literature. We also discuss a case study in which we are simultaneously dealing with side constrain...
Alternative mathematical models for revenue management problems
Terciyanlı, Erman; Avşar, Zeynep Müge; Department of Industrial Engineering (2009)
In this study, the seat inventory control problem is considered for airline networks from the perspective of a risk-averse decision maker. In the revenue management literature, it is generally assumed that the decision makers are risk-neutral. Therefore, the expected revenue is maximized without taking the variability or any other risk factor into account. On the other hand, risk-sensitive approach provides us with more information about the behavior of the revenue. The risk measure we consider in this stud...
A decision support system for production planning and pre-cost estimation activities in an apparel company
Gökalp, Ebru; Şen, Tayyar; Department of Industrial Engineering (2010)
In this study, a specific decision support system is designed and developed for Production Planning and Marketing Department of an apparel company. The developed system involves two modules with user friendly interface or data input and query. The system is designed to provide support in the following fields of decision making; pre cost estimation, capacity planning, master production planning and production scheduling. A detailed analysis of the existing system is conducted and Microsoft Access is used for...
Multi-objective route selection
Tezcaner, Diclehan; Köksalan, Murat; Department of Industrial Engineering (2009)
In this thesis, we address the route selection problem for Unmanned Air Vehicles (UAV) under multiple objectives. We consider a general case for this problem where the UAV has to visit several targets and return to the base. For this case, there are multiple combinatorial problems to be considered. First, the paths to be followed between any pairs of targets should be determined. This part can be considered as a multi-objective shortest path problem. Additionally, we need to determine the order of the targe...
Modeling of the dynamics of multi-axle steered vehicles
Bayar, Kerim; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2006)
Four wheel steering (4WS) is a concept proven to be beneficial in low speed applications requiring large steering angles, which is the case in city traffic or parking. By steering the rear wheels in the opposite direction to the front ones, maneuverability can be improved. However, a conflict is encountered at high speeds for all the steering strategies developed. If sharper response is achieved, this is at the expense of undesirably large vehicle sideslip angles. On the other hand, small vehicle sideslip a...
