Advancements in information technology enabled to track real time data in a more accurate and precise way in many manufacturing facilities. However, before obtaining the more accurate and precise data, the investment in information technology should be validated. Value of information may be adopted as a criterion in this investment. In this study, we analyze the value of information in a manufacturing facility where production and lead time quotation decisions are taken. In order to assess the value of information, two settings are analyzed. Under the first setting, the manufacturer takes decisions under perfect information. To find the optimal decisions under perfect information, a stochastic model is introduced. Under the second setting, the manufacturer takes decisions under imperfect information. To obtain a solution for this problem, Partially Observable Markov Decision Process is employed. Under the second setting, we study two approaches. In the first approach, we introduce a nonlinear programming model to find the optimal decisions. In the second approach, a heuristic approach, constructed on optimal actions taken under perfect information is presented. We examine the value of information under different parameters by considering the policies under nonlinear programming model and heuristic approach. The profit gap between the two policies is investigated. The effect of Make-to-Order (MTO) and Make-to-Stock (MTS) schemes on the value of information is analyzed. Lastly, different lead time quotation schemes; accept-all, accept-reject and precise lead time; are compared to find under which quotation scheme value of information is highest.

Guidelines for automating Phase I of control charts by considering effects on Phase-II performance of individuals control chart
Atalay, Murat; TESTİK, MURAT CANER; Duran, Serhan; Weiss, Christian H. (Informa UK Limited, 2019-09-11)
With the advances in measurement technologies, today products and processes may have hundreds of variables that can be monitored. As the number of variables to be monitored in a process increases, a cumbersome task is the design of control charts, especially when one needs to estimate unknown process parameters. In Phase-I control chart implementations, a set of samples that are ideally from an in-control process is formed by iteratively eliminating/retaining potentially out-of-control samples and this is t...

This thesis analyzes data collection tools and methods in domestic environments for smart product development processes. The aim of the study is to create a method for supporting data collection studies in user research of smart products at domestic environments. The study examines the utilization of information and communication technologies in ethnographic data collection methods at domestic environments with a qualitative approach. Two case studies are conducted to understand and analyze the effects of c...
A complex dynamical systems model of education, research, employment, and sustainable human development
Erdoğan, Ezgi; Azizoğlu, Meral; Department of Industrial Engineering (2010)
Economic events of this era reflect the fact that the value of information and technology has surpassed the value of physical production. This motivates countries to focus on increasing the education levels of citizens. However, policy making about education system and its returns requires dynamical analyses in order to be sustainable. The study aims to investigate the dynamic characteristics of a country-wide education system, in particular, that of Turkey. System Dynamics modeling, which is one of the mos...
Development of the holistic work system framework (hwsf) with the aid of information systems research design science guideline
Özalp, Egemen; Baykal, Buyurman; Department of Information Systems (2014)
Today almost every market, either service or industry, is utilizing Engineering or Information Technologies (IT) in their Work Systems (WS) extensively. Enterprises operating in these markets continuously seek methods to increase the efficiency and effectiveness of this utilization to gain Business Value, and achieve Business Goals. Works on Business Process Management (BPM), Technology Adoption (TA), or Enterprise Architecture (EA) are major instances of such methods. There are several models or standards ...
