Winter Simulation Conference 2018
ACT OR is attending the Winter Simulation Conference 2018 with the speech 'A Simheuristic Algorithm for Solving an Integrated Resource Allocation and Scheduling Problem'.
On December 12, Ludovica Maccarrone (Sapienza, ACTOR s.r.l.), Daniele Ferone (Universitat Oberta de Catalunya), Tommaso Giovannelli (Sapienza) and Javier Panadero and Angel A. Juan (Universitat Oberta de Catalunya) will present an application that uses simulation and a metaheuristic algorithm to solve an integrated problem of resource allocation and scheduling of activities (which use these resources). The objective is to provide a methodology able at the same time to take into account (1) the minimization of the costs of acquiring resources (for example the price of the necessary machinery or the wages to pay the labor), (2) the reduction of total time necessary to perform the planned activities (through an optimal scheduling and an appropriate allocation: having more resources to perform the activities allows to speed up the times) and (3) the variability of the processing times, which add uncertainty to the system and require then a statistical evaluation.
"Modern companies have to face challenging configuration issues in their manufacturing chains. One of these challenges is related to the integrated allocation and scheduling of resources such as machines, workers, energy, etc. These integrated optimization problems are difficult to solve, but they can be even more challenging when real-life uncertainty is considered. In this paper we study an integrated allocation and scheduling optimization problem with stochastic processing times. A simheuristic algorithm is proposed in order to effectively solve this integrated and stochastic problem. Our approach relies on the hybridization of simulation with a metaheuristic to deal with the stochastic version of the allocation-scheduling problem. A series of numerical experiments contribute to illustrate the efficiency of our methodology as well as their potential applications in real-life enterprise settings."
Something about the Winter Simulation Conference (WSC)
The WSC is the premier international forum for disseminating recent advances in the field of system simulation. In addition to a technical program of unsurpassed scope and quality, WSC provides the central meeting place for simulation practitioners, researchers, and vendors working in all disciplines in industry, service, government, military and academic sectors.
Simulation has been found useful for a range of scientific, engineering and business applications as evident by the papers presented at Winter Simulation Conferences over the past 50 years. Simulation has been employed to help noble causes too over the recent past but such efforts have received limited attention. The 2018 conference seeks to highlight applications of simulation for noble causes in addition to continuing to report leading developments and applications in other fields. The track sessions will feature uses of simulation in efforts analyzing and addressing issues facing humanity including, but not limited to, reducing poverty and world hunger, social causes, social problems, improving natural environment, and disaster response.
