15. Análise do comportamento dos tempos de produção em um sistema de manufatura flexível em um problema de escalonamento em um job shop: abordagem utilizando conceito de caminho crítico
In this work the Job Shop Scheduling Problem is studied, considering due dates, production turns and tooling constraints. This problem is applied in a Flexible Manufacturing System, which possesses high degree of automation, allowing previsibility in the processes of loading and unloading jobs on the machines. The problem is modeled through a objective funct

23. Influence of duty factor on the die-sinking Electrical Discharge Machining of high-strength aluminum alloy under rough machining
The use of high-strength aluminium alloys as material for injection molding tools to produce small and medium batches of plastic products as well as prototyping molds is becoming of increasing demand by the tooling industry. These alloys are replacing the traditional use of steel in the cases above because they offer many advantages such as very high thermal
