 Deseja-se modelar o problema:
Certa empresa fabrica 2 produtos P1 e P2. O lucro por
unidade de P1 é de $100,00 e o lucro unitário de P2 é de $150,00.
A empresa necessita de 2 horas para fabricar uma unidade
de P1 e 3 horas para fabricar uma unidade de P2. O tempo mensal
disponível para essas atividades é de 120 horas.
As demandas esperadas para os 2 produtos levaram a
empresa a decidir que os montantes produzidos de P1 e P2 não
devem ultrapassar 40 unidades de P1 e 30 unidades de P2 por mês.
Construa o modelo do sistema de produção mensal com o objetivo
de maximizar o lucro da empresa.
Problema Modelo
 Definir as variáveis:
 𝑥1: Quantidade do Produto 1 (P1);
 𝑥2: Quantidade do Produto 2 (p2);
Problema Modelo
Função de Lucro Máximo:
𝐿 𝑥1, 𝑥2 = 100𝑥1 + 150𝑥2
Restrição do tempo de produção:
2𝑥1 + 3𝑥2 ≤ 120
Restrição de produção:
𝑥1 ≤ 40
𝑥2 ≤ 30
Restrição da produção não negativa:
𝑥1 ≥ 0
𝑥2 ≥ 0
Problema Modelo
