In some practical situations the decision maker is interested in setting multi aspiration levels for objectives that may not be expressed in a specific manner. So in this paper, Atanassov’s intuitionistic fuzzy transportation problem with multi-item, multi-objective function assuming multiple choices is considered. We have modeled multi-objective multi-choice multi-item Atanassov’s intuitionist...

We present the framework of multiobjective fractional transportation problem in form pentagonal fuzzy supply and demand. The ideal model is set up to match decision makers’ preferences competing for criteria, costs, delivery time, degradation, environmental social concerns are objectives. employed flexible goal programming handle Model’s complexity improve reasonable compromise. real-world wind...

In this paper, a chance-constraint joint single vendor, single buyer supply chain problem with stochastic demand and fuzzy lead-time is investigated. The lead-time is lot size dependent; and delay times such as moving, waiting and setting time are fuzzy. The shortage costs result from backorder and/or lost sale, and the uncertain demand follows a uniform distribution. The buyer’s cost function ...

This paper presents the design of a fuzzy logic-based traffic scheduling algorithm aimed at reducing congestion for case partial obstruction bidirectional lane. Such problem is typically encountered in rail and personal rapid transportation systems with predefined fixed corridors. The proposed proportional-derivative (PD) control algorithm, serving as automaton, alternately assigns adaptive gre...
