Final answer:
Operations management is concerned with different technologies that aid in production efficiency. Production technology 3 is preferred for its lower costs, emphasizing a more machine-heavy approach. The technologies chosen are context-dependent but focus on cost-saving and productivity.
Step-by-step explanation:
Operations management is primarily concerned with various types of technologies that can improve the efficiency and effectiveness of production processes. In the context provided, production technology is mentioned in three different forms. While details about the specific types of technology are not given, we can infer that these options represent distinct methodologies or equipment used in production. It is noted that production technology 3 is the preferred choice due to its lower total cost. This selection is based on the economic principle that, when machine hours are less expensive, it is cost-efficient to use more machines relative to manual labor. Therefore, in operations management, the decision to choose a production technology often involves cost analysis and the consideration of labor versus machine use.
As such, the three kinds of technologies referred to might include: computer technology (such as software and computer peripherals), engineering tools (used by engineers to design systems), and advancements in changing the natural world to satisfy human needs. However, with the information given, it's clear that the specific types of technology chosen in operations management are highly context-dependent and are chosen with the aim of overall cost reduction and increased productivity.
