The production of steel normally constitutes the inception of most Supply Chains in different areas. Steel manufacturing companies are strongly affected by bull whip effects. Due to nondeterministic incoming orders and changes of customer requirements on accepted orders, making the right decision at a certain stage can be the difference between earning or loosing a great turnover. Improving the...

This paper presents current supply chain configurations for concrete reinforcement steel (rebar) in the Turkish construction industry. The supply chains were assessed by the value stream mapping method and were investigated through visits to firms involved in the supply chain and interviews with practitioners. Five different types of rebar supply chain configurations were identified in the case...

–Supply Chain Management emerged as one of the most powerful business improvement tool available today. A number of SCM practices such as supplier, customer, ERP, subcontracting, E-procurement, EDI, E-commerce have been addressed in Indian manufacturing industries and a conceptual model was formulated based on previous literature and a questionnaire developed, survey was performed. This paper e...

in this research, we address the application of uncertaintyprogramming to design a multi-site, multi-product, multi-period,closed-loop supply chain (clsc) network. in order to make theresults of this article more realistic, a clsc for a case study inthe iron and steel industry has been explored. the presentedsupply chain covers three objective functions: maximization ofprofit, minimization of n...

Lăzăroiu, Spiru Haret University, Bucharest, Romania The theory that we shall seek to elaborate here puts considerable emphasis on technological features of China’s steel production, its emergence as the world’s most significant steel producer and main manufact...

One of the primary objectives of supply chain (SC) system analysis and modeling is to develop conceptual design of organizational and process knowledge models, which facilitates optimal supply chain management. SC knowledge modeling consists of two components: 1) modeling SC workflows, and 2) capturing and organizing knowledge necessary for managing them. Workflow modeling deals with handling a...

Cost reduction is one of the methods applied for improving the productivity of organizations. In productivity literature, particularly in nonparametric methods, cost reduction related methods are regarded as input oriented models. This paper presents a Supply Chain Management (SCM) model in which purchasing iron ore and coke from different resources, along with production and distribution of st...

Abstract: This study relies on integrated inventory theory which merges with the supply chain concept and aims at the steel bar material of precast factory’s two-echelon supply chain system. In order to consider the variable demand rate, unfixed supply time, unfixed supply frequency and unfixed supply quantity, this study builds a strategic model that minimizes the total inventory cost of all p...
