Unlike commonly used methods, in this paper, we have introduced a new approach for designing fuzzy controllers. In this approach, we have simultaneously optimized both objective functions of a supply chain over a two-dimensional space. Then, we have obtained a spectrum of optimized points, each of which represents a set of optimal parameters which can be chosen by the manager ...

We consider a supply chain consisting of a sequence of buffer queues and processors with certain throughput times and capacities. Based on a simple rule for releasing parts, i.e. batches of product or individual product items, from the buffers into the processors we derive a hyperbolic conservation law for the part density and flux in the supply chain. The conservation law will be asymptoticall...

This research work develops a decision support model for a network design problem concerning a spare parts closed loop supply chain. It involves the formulation of an optimization model that takes on a mid to long-term planning perspective and covers decisions that have lasting and binding impact on organizational performance. These decisions include investment, location assignment, and invento...

the purpose of this research is to identify factors and components that affect a trust-based cooperation in the automobile supply chain and their impact on the performance of the supply chain companies. this paper includes 2 parts. in the first part, by studying the research history and literature and interviewing academic and industrial scholars and experts, four hidden variables of trust-base...

Establishing connectivity of products with real-time information about themselves can at one level provide accurate data, and at another, allow products to assess and influence their own destiny. In this way, the specification for an intelligent product is being built – one whose information content is permanently bound to its material content. This paper explores the impact of such development...

We focus on the auto industry supply chains in India. The Indian auto industry is small in size, compared to the world markets ($ 6.73 billion compared to a world market of $ 737 billion) but has experienced a growth rate of 20-25 % the past few years. Over 13 Indian companies have won the Deming prize and quality has improved significantly. We focus on empirical data in this industry and expla...

We trace the evolution of the auto component supply chain in India (following the opening of the Indian economy in 1990) using a combination of data on firm and sectoral performance, customer satisfaction surveys and interviews with experts. During the last decade, the industry has made remarkable progress on multiple fronts. This is particularly true with regard to quality ten firms in this in...

In many industrial sectors, firms are dealing with a demand which is more and more uncertain often due to the supply chain structure. One of the most critical effects of demand uncertainty is the simultaneous increase of inventories and decrease of customer service. This work describes an integrated system for managing inventories in a multi-echelon spare parts supply chain, in which customers ...
