What is the structure is commonly known as the reliability of the structure

1. The functional requirements of the structure and the safety, applicability and durability of the limit state are summarized as the reliability of the structure.

2. The safety, applicability and durability of the structure are collectively referred to as the reliability of the structure. Safety The structural system should have a reasonable force transmission path that can transmit various effects that the structure may withstand from the action point to the resistance component.

3. The safety, applicability and durability of the structure are commonly known as the reliability of the structure. Safety Under the conditions of normal construction and normal use, the structure should be able to withstand various loads and deformations that may occur without damage; after accidental events, the structure can still maintain the necessary overall stability.

4. [Answer]: D According to the definition of Article 1 of the Uniform Standard for the Design of Building Structure Reliability (GB50068-2001), the ability of a structure to complete the predetermined function within the specified time and under the specified conditions is called the reliability of the structure.

5. [Answer]: A, C, D 2021/2020 version of textbook P13 Safety, applicability and durability are generally referred to as the reliability of the structure.

6. Safety, applicability and durability are collectively referred to as the reliability of the structure. If the structure can meet the functional requirements, it is called structural reliability; on the contrary, if the structure is unreliable, its boundary point is called the limit state.

The difference between safety, stability and reliability of power systems

Stability and reliability are two important concepts related to product or system performance. They have the following differences: Definition: Stability refers to the ability of a system or product to maintain stable operation, that is, to maintain normal operation under various conditions without unexpected failures or system crashes.

The evaluation indicators are different. The evaluation indicators of reliability are: reliability, average fault-free interval, and inefficiency. The evaluation indicator of stability is the comprehensive characteristics of maintainability and maintenance support of a certain time node.

Information management is divided into production management area (safety zone III) and management information area (safety zone IV). Different security zones determine different security protection requirements, among which the security zone I has the highest security level, the security zone II is the second, and the rest are analogy in order.

What is operations planning

1. As a modern science, operations planning was first developed in Britain and the United States during World War II. Some scholars describe operations as the science that makes decisions on various operations of the organizational system. Means.

2. Linear planning is a branch of operations planning that is relatively complete and mature in theory, and the method is relatively convenient and effective. However, it can still be used to solve the problems of some large-scale systems. It has the characteristics of intuitive description of problems, easy calculation and implementation of models, and can easily decompose or transform some complex problems. Sub-problems that can be solved.

3. As a discipline, operations planning emerged from the study of the allocation of weapons, the deployment of troops and the transfer of military supplies during World War II.

4. Operations planning is an important professional basic course of modern management. This discipline is applied to the interdisciplinary research of mathematics and formal science, using methods such as statistics, mathematical models and algorithms to find the best or near-best solution planning generalization in complex problems.

5. Introduction: Operations planning is an important professional basic course of modern management. It is an emerging discipline developed in the early 1930s. Its main purpose is to provide a scientific basis for managers when making decisions. It is one of the important ways to achieve effective management, correct decision-making and modern management.

6. Therefore, obtaining maximum benefits with limited resources is an issue considered by every competitor, which is also a problem that economics and operations planning focus on solving. Operational planning is a discipline that takes mathematics as the main means and focuses on the study of optimal problem solving.
