Increasing e-commerce activity, competition for shorter delivery times, and innovations in transportation technologies have pushed the industry toward instant logistics. This paper studies a facility location online demand allocation problem applicable to logistics company expanding offer service using unmanned aerial vehicles or drones. The is decomposed into two stages. During planning stage,...

in this paper, the effects of roll center height of mcpherson suspension mechanism on dynamic behaviour of a vehicle is studied first and then the optimum location of roll center of this suspension system is determined for a conceptual class a vehicle. adams/car software was used for analysis of vehicle dynamic behaviour in different positions of suspension roll center, then optimization proces...

The Soft-Capacitated Facility Location Problem, where each facility is composed of a variable number of fixed-capacity production units, has been recently studied in several papers, especially in the metric case. In this paper, we only consider the general problem where connection costs do not systematically satisfy the triangle inequality property. We show that an adaptation of the set coverin...

This article introduces several algorithms for finding a representative subset of the non-dominated point set of a biobjective discrete optimization problem with respect to uniformity, coverage and the -indicator. We consider the representation problem itself as multiobjective, trying to find a good compromise between these quality measures. These representation problems are formulated as parti...

In this study, we have classified different types of problems which are related to facility planning and layout design for different types of manufacturing processes. The main problems which are related to location of facilities which also affects the system performance such as distribution of man, material and machine in a plant or a factory and their optimization technique while using of math...

A facility layout problem is concerned with determining the best position of departments, cells, or machines on the plant. An efficient layout contributes to the overall efficiency of operations. It’s been proved that, when system characteristics change, it can cause a significant increase in material handling cost. Consequently, the efficiency of the current layout decreases or is lost and it ...

Title of dissertation: ON THE ROUTING AND LOCATION OF MOBILE FACILITIES Russell David Halper Doctor of Philosophy, 2010 Dissertation directed by: Professor Subramanian Raghavan AMSC Program R.H. Smith School of Business Mobile facilities play important roles in many applications, including health care, public services, telecommunications, and humanitarian relief logistics. While mobile faciliti...

The Existence of crack in a structure leads to local flexibility and changes  the stiffness and dynamic behavior of the structure. The dynamic behavior of the cracked structure depends on the depth and the location of the crack. Hence, the changes in the dynamic behavior in the structure due to the crack can be used for identifying the location and depth of the crack. In this study the first th...

The continuous-space single- and multi-facility location problem has attracted much attention in previous studies. This study focuses on determining the globally optimal facility locations for two- higher-dimensional problems when Manhattan distance is considered. Before we propose exact method, start with single-facility obtain global minimizer using a statistical approach. Then, an method dev...
