In today's life, companies are faced with the problem of providing quality goods and services at competitive prices. Cost estimation is a very important process for a forging company, as each time a quote is sent to a customer, the company earns or loses money depending on the results of the particular estimate. However, determining pricing for customer quotes is a matter of time consuming, detailed number of tasks repeated each time. Cost estimation software might do those tedious calculations and assist the estimator step by step to reach to a cost estimate in relatively short time. In this study, an interactive cost estimation software named "Forge Cost Estimator", which performs the early cost estimation for forgings, has been developed. The program is aimed to be used by the cost estimators in hot forging companies. The software has various databases, which include material, forging and machining equipment data. The cost items defined in the forging work breakdown structure can be estimated by using different modules of the software and summed up in an additive structure by using the bottom-up cost estimation method. For calculating the forge volume quicker and easier, a new volume estimation system named "Easy-Volume", which is based on the volume fragmentation method, is proposed. The software can also guide the user in selecting the convenient forging production line. The software is written in MS Visual Basic 6.0. The developed program has been tested in a forging company and satisfactory cost estimations for several forgings have been achieved.

Information And Price Dispersion On Net
Civan, Abdülkadir; Oktay, Murat; Tunc, Cengiz (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2008-12)
Internet firms charge a wide range of prices for nearly homogeneous products and price dispersion vary significantly across markets. This study is an attempt to explain different levels of price dispersion across online product markets. We found price dispersion vary systematically with the number of firms offering the product and the markets at which consumers are more informed have smaller price dispersion. Moreover prices charged by individual retailers decline as the number of retailers selling the same...
Network Analysis Algorithm for the Solution of Discrete Time-Cost Trade-off Problem
BETTEMİR, ÖNDER HALİS; Birgönül, Mustafa Talat (2017-05-01)
Optimum solution of time-cost trade-off problem has significant importance since it provides the highest profit opportunity. For this reason, exact, heuristic, and meta-heuristic algorithms are adapted to obtain the optimum or near-optimum solution. However, heuristic algorithms may not always converge into the global optimum, while meta-heuristic algorithms require significant computation to converge into global optimum and exact methods are complex for construction planners to implement. Therefore, minimu...
A model for evaluating the potential of litigation due to contract ambiguity in international construction projects
Yenişehirlioğlu, Ahmethan; Sönmez, Rifat; Department of Civil Engineering (2022-8)
Disputes are unavoidable due to the unique interests of the parties and the challenging, complex and oppositional nature of the industry in the construction sector. For this reason, many researchers have conducted studies on disputes and dispute resolution in construction projects. Litigation, which is the last resort of disputes, is an unwelcomed process for all parties causing loss of time, money and reputation. In this respect, both the owner and the contractor require to prevent the factors that cause d...
Modeling and predicting customer purchase behavior in the grocery retail industry
Peker, Serhat; Koçyiğit, Altan; Department of Information Systems (2017)
In today’s business, grocery retail industry companies operate in highly competitive environment. Such an intense competition have compelled companies to develop close and long-term relationships with their customers by implementing more targeted marketing strategies and personalized services. To implement such customized services, modelling and predicting customer purchase behaviors are essential. Accordingly, this thesis mainly aims to model and predict the customers’ purchasing behavior in the grocery re...
STOCHASTIC MODELING OF STOP-LOSS REINSURANCE AND EXPOSURE CURVES UNDER TIME DEPENDENT STRUCTURE
Mert, Özenç Murat; Kestel, Sevtap Ayşe; Department of Financial Mathematics (2022-12-2)
Insurance markets play an essential role in the economy of the world and its structure requires reinsurance policies due to the growth in populations, extreme (catastrophic) events, political and economical perspectives. In this thesis, stop-loss contracts, one of the reinsurance policy types, are covered for two different contract types: (i) contracts with retention and (ii) contracts with both retention and cap (maximum). This thesis covers two different methodologies, distributional and stochastic behavi...
