Supplier selection is one of the most important activities in supply chain management. Aim of this process is to find suppliers which have the most compatible specifications with buyer`s requirements. This study develops an integrated approach by applying intuitionistic fuzzy set and linear programming technique. It uses two indicators to explain supplier's(More)
This paper proposes a group decision-making process by using multi-objective programming to address three-dimensional concurrent engineering (3D-CE) problems involving product, process and supply chain design. This paper uses opinion of decision makers to evaluate of the candidate suppliers and to determine importance of criteria by considering lack(More)
In this paper, synchronization of chaotic systems with unknown parameters and unmeasured states is investigated. Two nonidentical chaotic systems in the framework of a master and a slave are considered for synchronization. It is assumed that both systems have uncertain dynamics, and states of the slave system are not measured. To tackle this challenging(More)
One of the great challenges of most of the investment companies is the analysis of investment costs in the development of new products, in the initial stages of production. This study develops the appropriate methods for the analysis of kinds of investment costs, within the three-dimensional concurrent engineering. This study presents a suggested model(More)
