Abstract During past few decades, fuzzy decision is an important attention in the areas of science, engineering, economic system, business, etc. To solve day-to-day problem, researchers use data transportation problem for presenting uncontrollable factors; and most multi-objective problems are solved using goal programming. However, when contains interval-valued data, then obtained solution was...

We study a multiechelon supply chain model that consists of a production level and several transportation levels, where the demands can exist in the production echelon as well as any transportation echelons. With the presence of stationary production capacity and general cost functions, our model integrates production, inventory and transportation decisions and generalizes existing literature o...

The Fixed Charge Transportation Problem (FCTP) is a generalization of the well-known Transportation Problem, where the cost for sending goods from origins to destinations is composed of a fixed cost and a continuous cost proportional to the amount of goods sent. In practical applications, the fixed costs may represent toll charges on highways, landing fees at airports, setup costs in production...

This paper presents a branching method for the solution of the fixed charge transportation problem. Starting with a linear formulation of the problem, we develop the method which converges to the optimal solution. The method is based on the computation of a lower bound and an upper bound embedded within a branching process. We present a detailed numerical example to illustrate the proposed meth...

for the urban transportation because of their sustainability, High torque, low volume, zero emission and energy saving. Electric scooter can go certain limit of distance based on the battery capacity it consists. This paper presents the model construction of an energy regenerative electric scooter via MATLAB/SIMULINK so that one can evaluate the performance of the energy recycling technique for...
