Concept explainers
(a)
To determine: The quantities of H and W that can maximize profits by using both the objective function method and enumeration method when a manufacturer produces two models of ovens H and W which need fabrication and assembly work. Each H uses 4 hours of fabrication and 2 hours of assembly, and each W model uses 2 hours of fabrication and 6 hours of assembly. Total fabrication hours that are available this week are 600 and 480 for assembly hours. Each H model contributes $40 to profits and each W contributes $30 to profits.
Introduction: A trend equation is used to calculate or identify the expected level of output according to the trend followed by sales.
(b)
To determine: How many units of every model needed to be produced if the goal is profit maximization by using the objective function method and enumeration method where two refrigerator models L and M involve limited hours for assembly and fabrication. 540 hours are available for fabrication and 600 hours for assembly this week and each model of L needs 6 hours for fabrication and 3 hours for assembly whereas, M needs 4 hours of fabrication and 5 hours for assembly. Every unit or model of L contributes $50 to profit and M produces $40. Therefore, it is needed to determine
