A new collaborative system framework based on a multiple perspective approach: InteliTeam

Çil, İbrahim; Yazğan, Harun Reşit (ELSEVIER SCIENCE BV, 2005)

This study develops a Web-based collaborative system framework based on a multiple perspective approach. This framework is a recent decision support system (DSS) paradigm proposed by Courtney [Decis. Support Syst. 31 (2001) ...
A novel hierarchical approach for a heterogeneous 3D pallet loading problem subject to factual loading and delivery constraints

Kır, Sena; Yazğan, Harun Reşit (INDERSCIENCE ENTERPRISES LTD, 2019)

This paper presents a hierarchical approach, which consists of a two-stage genetic algorithm and a mixed integer linear programming, for a heterogeneous three-dimensional pallet loading problem in consideration of the ...
A rule-based master production scheduling system for an electro-mechanical manufacturing company

Gündoğar, Emin (TAYLOR & FRANCIS LTD, 1999)

It is a hard process to modify master production schedule in a Firm having various types of products and final assembly groups. Therefore, the system should automatically make the needed and proper modifications when they ...
A stochastic programming model for resequencing buffer content optimisation in mixed-model assembly lines

Günay, Elif Elçin; Kula, Ufuk (TAYLOR & FRANCIS LTD, 2017)

In mixed-model assembly lines, smooth operation of the assembly line depends on adherence to the scheduled sequence. However, during production process, this sequence is altered both intentionally and uninstentionally. A ...
Advances in Intelligent Systems and Computing

Akbilek, Nevra; Rhm Goossens (SPRINGER INTERNATIONAL PUBLISHING AG, 2018)

Ergonomics plays an important role in occupational safety, productivity and occupational diseases. For this reason, the creation of the auxiliary equipment or the machine and the work place designs to improve human life ...
An ERP software selection process with using artificial neural network based on analytic network process approach

Yazğan, Harun Reşit; Boran, Semra (PERGAMON-ELSEVIER SCIENCE LTD, 2009)

An ANN model has been designed and trained with using ANP results in order to calculate ERP software priority. The artificial neural network (ANN) model is trained by results obtained from ANP. It seems that there is no ...
Artificial neural networks for design of manufacturing systems and selection of priority rules

Çakar, Tarık; Çil, İbrahim (TAYLOR & FRANCIS LTD, 2004)

Simulation is one of the most effective methods in the Design of Manufacturing Systems (MS). Typical reasons for simulation of a manufacturing system includes evaluating the capacity and equipment utilization, identifying ...
Comparative analysis for periodical and random servicing systems considering different working circumstances: A textile application

Engin, Ahmet Baki (SOC MANUFACTURING ENGINEERS, 2009)

As is in the textile industry, in some industries the selection of the operator servicing system to improve machines' efficiencies is made intuitively or according to historical experiences generally. However, these ...
