6. Какое утверждение ложно?

Ответы:

− Модель с фиксированным периодом довольно устойчива к увеличению спроса, задержке поставки, неполной поставке и занижению размера заказа

+ Чем больше у предприятия запасов, тем лучше

− Новые, только что запускаемые в продажу продукты нуждаются в более высоком уровне запасов по сравнению с товарами, спрос на которые уже падает

− Модель управления запасами с установленной периодичностью ориентирована на работу при значительных колебаниях потребления

− Система «максимум-минимум» ориентирована на ситуацию, когда затраты на учет запасов и издержки на оформление заказа настолько значительны, что становятся соизмеримы с потерями от дефицита запасов

Cognitive psychology
1. Cognitive psychology is a discipline within psychology that investigates the internal mental processes of thought such as visual processing, memory, problem solving, and language. The school of thought arising from this approach is known as cognitivism which is interested in how people mentally represent information processing.
2. Cognitive psychologists use psychophysical and experimental approaches to understand, diagnose, and solve problems, concerning themselves with the mental processes which mediate between stimulus and response.
3. Cognitive science differs from cognitive psychology in that algorithms that are intended to simulate human behavior are implemented or implementable on a computer. In other instances, solutions may be found through insight, a sudden awareness of relationships.

Plasma Cutters
1. Modern industry depends on the manipulation of heavy metal and alloys. We need metals to build the tools and transportation necessary for day-to-day business. The reason is simple: metals are extremely strong and durable, so they're the logical choice for most things that need to be especially big, especially sturdy, or both.
2. The funny thing is that metal's strength is also a weakness: because metal is so good at resisting damage, it's very difficult to manipulate and form into specialized pieces. People can precisely cut and manipulate the metals using the plasma cutter. The plasma cutter is actually a common tool that has been around since World War II.
3. Plasma cutters are not the only devices to harness the power of plasma. Neon signs, fluorescent lighting and plasma displays, just to name a few, all rely on it to get the job done. These devices use "cool" plasma. Though cool plasma cannot be used to cut metals, it has tons of other useful applications.

Vacuum
1. Evangelista Torricelli produced the first laboratory vacuum in 1643, and other experimental techniques were developed as a result of his theories of atmospheric pressure. A torricellian vacuum is created by filling a tall glass container closed at one end with mercury and then inverting the container into a bowl to contain the mercury.
2. The quality of a vacuum refers to how closely it approaches a perfect vacuum. Residual gas pressure is a primary indicator of quality, and is most commonly measured in units called torr, even in metric contexts. Lower pressures indicate higher quality, although other variables must also be taken into account.
3. Vacuum became a valuable industrial tool in the 20th century with the introduction of incandescent light bulbs and vacuum tubes, and a wide array of vacuum technology has since become available. The recent development of human spaceflight has raised interest in the impact of vacuum on human health, and on life forms in general.

Teaching
1. Good teaching is not a matter of techniques or methods, for, as curriculum is not education, so method is not teaching. Research indicates that good teachers cannot be differentiated on the basis of «teaching methods». The method is inseparable from the person of the teacher; in fact, the person of the teacher is more important than the method.
2. The good teacher is not an instructor, who simply provides information, facts and knowledge but a facilitator of learning for the student. Good teachers are not those who are simply experts in subject matter, or experts in teaching methods, or curriculum experts, or who utilize the most resources, such as audiovisual aids.
3. The best teacher is one who, through establishing a personal relationship, frees the student to learn. Learning can only take place if the student and the teacher can create the conditions for learning. The atmosphere created by a good interpersonal relationship is the major condition for learning.

Automation
1. Automation is the use of control systems in concern with other applications of information technology to control industrial machinery and processes, reducing the need for human intervention. In the scope of industrialization, automation is a step beyond mechanization.
2. Automation plays an increasingly important role in the world economy and in daily experience. Engineers strive to combine automated devices with mathematical and organizational tools to create complex systems for a rapidly expanding range of applications and human activities.
3. Many roles for humans in industrial processes presently lie beyond the scope of automation. Tasks requiring subjective assessment or synthesis of complex sensory data, such as scents and sounds, as well as high-level tasks such as strategic planning, currently require human expertise. In many cases, the use of humans is more cost-effective than mechanical approaches even where automation of industrial tasks is possible.
