Simulation of capacity expansion and sequencing alternatives for a sheet metal producer

We present a simulation case study carried out for a make-to-order aluminium sheet producer located in Istanbul, Turkey. We are concerned with a subsystem of the factory consisting of continuous casting, cold rolling, and annealing processes. Two simulation models are developed: (1) a combined model for studying the casting process only; (2) a discrete event model for comparing capacity expansion alternatives and order sequencing rules in the subsystem. Operational characteristics of the real system and past data are extensively analysed for modelling and validation purposes. Capacity expansion and sequencing alternatives are evaluated in an experimental design setting with the objectives of satisfying the demand, balancing the process loads, and keeping the work-in-process inventory under control.


Analysis and improvement of the product delivery system of a beer producer in Ankara
Pamuk, S; Köksalan, Mustafa Murat; Gullu, R (Informa UK Limited, 2004-11-01)
We outline our analysis of the product delivery system of a major beer producer in Ankara, Turkey. We demonstrate a savings potential of up to 25% of distribution costs from the implementation of a number of suggested improvements, most notably that of reducing the number of weekly deliveries to a portion of the customers, and of constructing a geographical partitioning of the city that ensures a balanced distribution of the delivery workload over the days of the week. A geographic information system (GIS) ...

Robust portfolio planning in the presence of market anomalies
Oguzsoy, Cemal Berk; Güven, Sibel (Elsevier BV, 2007-02-01)
In this study, a short-term portfolio modeling formulation is developed using existing anomalies as a single determinant for daily Istanbul Stock Exchange National 100 Composite Index (ISE) and US dollars (USD) returns in a Robust optimization (RO) framework. Using anomalies in planning within an RO framework establishes a balance between risk seeking and risk averse behaviors, as generating profit from anomalies is risky and RO enables to settle down the extreme risk seeking behavior. Applications of the m...
Fuzzy Assessment Model to Estimate the Probability of Delay in Turkish Construction Projects
Gunduz, Murat; Nielsen, Yasemin; Ozdemir, Mustafa (American Society of Civil Engineers (ASCE), 2015-07-01)
The aim of this paper is to propose a decision support tool for contractors before the bidding stage to quantify the probability of delay in construction projects in Turkey by using the relative importance index (RII) method incorporated into fuzzy logic. For this purpose, 83 delay factors were identified, categorized into 9 major groups through a detailed literature review process as well as interviews with experts from the construction industry. The relative importance of these delay factors and groups wa...
Quantiative Methodology for Determination of Cost Contingency in International Projects
Sönmez, Rifat; Birgönül, Mustafa Talat (American Society of Civil Engineers (ASCE), 2007-01-01)
This paper presents a quantitative methodology to determine financial impacts of the risk factors during the bidding stages of international construction projects. Project and country data of 26 construction projects from 21 countries were collected for evaluation of the international risk factors. The factors impacting cost contingency were identified using correlation and regression analysis techniques. The results indicated that four factors had major contributions for explaining the variations in the co...
