Waste clean-up after a disaster is one of the most critical tasks in response stage management. We develop model to minimise cost and duration waste considering using Temporary Disaster Management Sites (TDWMSs), which can store process before it sent final disposal sites. The problem that arises be seen as Multi-Period Two-echelon Location Routing Problem (MP-2ELRP) main decisions are location...

This paper proposes a new location problem of competitive facilities, e.g. shops and stores, with uncertain demands in the plain. By representing the demands for facilities as random variables, the location problem is formulated to a stochastic programming problem, and it is reformulated to three deterministic programming problems: expectation maximizing problem, probability maximizing problem,...

This paper proposes a new location problem of competitive facilities, e.g. shops and stores, with uncertain demands in the plane. By representing the demands for facilities as random variables, the location problem is formulated to a stochastic programming problem, and for finding its solution, three deterministic programming problems: expectation maximizing problem, probability maximizing prob...

Abstract This paper introduces the multi-depot open location routing problem (MD-OLRP) with a heterogeneous fixed fleet. The is inspired by collection of company which collects raw materials from different suppliers coordinating several carriers. Each carrier has Moreover, there cost for contracting each vehicle and variable associated distance traveled. empty haul return to vehicles depot not ...

Multi-facility location problem is a type of task often solved (not only) in logistics. It consists finding the optimal required number centers for given points. One possible solutions to use principle genetic algorithm. The Solver add-in, which uses evolutionary method, available Excel office software. was used solve benchmark 4 levels difficulty (from 5 25 points 20 100 points), and one from ...
