Abstract
Wafer slicing in photovoltaic industry is mainly done using multiwire saw machines The selection of set of bricks parallelepiped block of crystalline silicon to be sawn together poses difficult production scheduling decisions The objective is to maximize the utilization of the available cutting length to improve the process throughput We address the problem presenting a mathematical formulation and an algorithm that aims to solve it in very short running times while delivering superior solutions The algorithm employs a reactive greedy randomized adaptive search procedure with some enhancements Computational experiments proved its effectiveness and efficiency to solve realworld based problems and randomly generated instances Implementation of an online decision system based on this algorithm can help photovoltaic industry to reduce slicing costs making a contribution for its competitiveness against other sources of energy
