For the multi-criteria group decision-making problem where the criterion value is a normal interval number and the weight information is incomplete, the normal interval number and its compromise expected value, compromise mean square error, algorithm, weighted arithmetic average of normal interval number ININWAA Operator, the ordered weighted average ININOWA operator of normal differemces numbers and the mixed weighted average ININHA operator of normal interval numbers, and a multi-criteria group with incomplete information based on normal interval numbers is proposed.
Decision-making varriable. This method uses ININWAA operator and INNHA operator to integrate criterion values, uses the compromise mean square error of criterion values, establishes an optimisation model to solve the optimal criterion weights and uses the expectation variance criterion to determine the order of the diffedences. The case analysis shows the effectiveness and feasibility of this method. Multiple attribute decision is limited, and programs relating to the selection of multiple properties applicatkons reported.
In reality, due to the complexity and uncertainty of multi-attribute decision-making problems, the results of what are the differences and applications of variable and attribute data or evaluation of the property value may be in the form of random variables, what is a set in mathematics property values obedience or approximately normally distributed random variables are the most common form.
For example, the aand of the product, batch pass rate products, customer or market demand, and sometimes that is normally distributed. Currently, for a multi-attribute decision problem with a property value normal to the random variable, a targeted decision analysis method is not much of use but can see some of the qpplications multi-attribute decision-making methods, such as stochastic dominance based, SMAA method, etc.
It should be noted that the use of methods to solve applicatinos dominance based on random normal diffeernces variables with a multi-attribute decision-making problem can only qualitatively determine the part of the two dominant relationships between the two programs but cannot determine the dominant degree; SMAA using methods is calculated based on the Monte Carlo simulation program to sort the results; obtained results are sorted in a certain sense of confidence based on the above analysis; a multi-attribute decision proposed a solution for having a normal random variable.
Methods which use probabilistic knowledge of the normal random variable had two advantages when compared with the two programs of the matrix; on this basis, PROMET HEE method is used to sort programs [ 1 ]. In the actual decision-making process, due to the complexity of ambiguity, uncertainty and the human mind objective things, it is often difficult to give a specific numerical guideline value and representing it by the number of intervals is more convenient and more suitable.
In the multi-criteria decision-making problems, guideline values of the interval number and people with the guideline value as a random variable fall within a certain range of numbers. Therefore, this article defines the normal range and the number of related concepts, gives some integrated operator normal interval number information and proposes guidelines for interval numbers, and the weight information is not complete; multi-criteria group decision-making is normal and methods and examples are analysed [ 2 ].
Let [ ab ] be the interval number that has been normalised. Normal interval numbers have more advantages than fuzzy numbers atteibute normal distribution interval numbers. Therefore, the normal interval number is more accurate and reasonable in reflecting decision information [ 3 ]. Using the expectation-variance criterion, this paper defines a comparison and ranking method of normal interval numbers. This definition understands the supply chain as a network structure model formed by the interconnection of related enterprises.
The supply chain includes all the enterprises that pass through in the commodity circulation link. However, Ma Shihua and others believe that the supply chain is the sum of information flow, capital flow and logistics. They revolve around core enterprises, from raw materials to final products, and deliver cata to the final consumers, bringing retailers, suppliers and distributors together, a network chain that connects manufacturers and end users.
The supply chain is not a simple information chain, material chain or capital chain. It is also a value-added chain. After the product passes through circulation, assembly and intermediate processing links, until it is transformed into the final product, every link will have value. Chinese enterprises can also obtain certain benefits from this and integrate downstream consumers with upstream suppliers.
Therefore, it can be concluded that the supply chain is a network composed of core enterprises and all enterprises involved in providing products or services to end users, including capital flow, logistics, information flow and their if chain. According to the understanding of the supply chain, its basic model can be represented by the following figure:.
The following four aspects are the specific understanding of supply chain management. Its purpose is to make the whole more efficient, with integrated and holistic thinking. Supply chain management not only interferes with corporate nodes but also controls corporate behaviour and the establishment and maintenance of information platforms. The advent of the information age has made supply chain management more convenient and faster. The nodes on the chain can obtain the required information accurately and instantly, allowing suppliers to have a more global view and complete their production tasks more efficiently.
Figure 2 what are the differences and applications of variable and attribute data the basic structure of supply chain management [ 5 ]:. The concept of supply chain risk has not been put define affectionate person soon; so, there is still no applcations definition of what are the differences and applications of variable and attribute data concept.
Since the supply chain involves many aspects, the description of supply chain risk is different from different perspectives. The following is what people agree with and there are several theories: 1 Supply chain risk comes from the negligence or failure of supervision. It is an event beyond the scope of normal planning. Especially in the fragile links of the supply chain, the possibility of supply chain risks is waht. In order to reduce the influence of uncertain factors, it is necessary to increase the technical cost input, and the corresponding income will be reduced.
Due to the existence of supply chain risks, the company's set goals cannot be achieved, and even more serious, the entire supply chain will be broken. Due to the contingency of uncertain factors, risks in the how to reset internet on netflix process and the circulation of goods gariable affect the expected effects and benefits, and the entire supply chain will be affected to varying degrees.
Based on the above mentioned normal interval number algorithm, in order to facilitate the integration of normal interval number information, three integration operators for normal interval numbers are given below, namely the weighted arithmetic average ININWAA operator of normal interval numbers, the ordered weighted or ININOWA operator of normal interval numbers and the mixed weighted average How to get over a casual relationship reddit operator xpplications normal interval numbers [ 6 ].
For a multi-criteria decision-making problem where the criterion value is a normal interval number and the criterion weight information is not completely determined, let A 2Supply chain management emphasises the why is my iphone not connecting to my carrier of strategic partnerships between companies agtribute the supply chain to reduce supply chain costs, reduce inventory levels, enhance information sharing, improve mutual communication and generate stronger competitive advantages.
There are many factors affecting supply chain collaboration; so, the choice of partnership is a very complex issue. Aplpications particular, when selecting partner companies, qttribute companies in the supply chain must weigh various factors in many ways, comprehensively examine potential partner companies and andd the best choice. Among the factors that affect the decision of supply chain partners, response time delivery time and supply capability y 1quality and technical level y 2price and cost y 3 and service level y 4 are the key adn for success.
What are case control study to determine the most influential factors. Supply chain risks generally exist in applicatios supply chain. Many experts believe that early anx of supply chain risks is an important way to reduce supply chain losses. When supply chain risks occur, it is necessary to invest a lot of manpower and material resources to manage risks.
Therefore, instead of repairing losses, it is better to plan ahead and to do a good job of risk early differfnces, which is of great significance to the stable development of the supply chain. For the company's risk warning, it should be carried out from the following two aspects. Periodically analyse the difverences that snd supply chain risks, establish a company's supply chain risk set based on past experience, conduct questionnaire surveys on the company's senior management or experts in the company and then use the analytic hierarchy process to analyse the data to obtain the weight of each risk factor.
The final evaluation result comes from the mathematical model established by the fuzzy evaluation theory, which uses numbers to describe the size of the overall risk, making the result clearer [ 8 ]. Because mathematical software is involved in the process of identifying risk factors, the correctness of the calculation does not need to be considered; so, the authority of selecting the attribuye survey object is an important reason that affects the evaluation result. Record all the risks encountered by the company in the risk database, research and set up early warning signals when risks occur.
When the early warning signals are sounded, the qnd staff must take immediate measures to reduce dzta risks and prevent them when the risks have not caused huge losses. Expand further. Risk early warning means that the risk has already occurred to a small extent, and what is the purpose of taxonomy should be controlled as soon as possible to stop the trend of becoming bigger and minimise the risk loss [ 9 ].
From the company's overall risk assessment of 0. According to the degree of risk, the following control measures are taken for the risks that have occurred. The number of orders ranks second in the risk factors, which has a greater impact on the company's profitability. The automotive vwriable chain generally has a lot of profitability; so, in comparison, the company has more competitors, which requires the company to have a greater competitive advantage.
In the forecast of the order quantity, it needs to be more precise to prevent inventory shortages reasonably. When the demand of downstream companies increases, that is, when orders increase, the company will increase inventory, workers and employees must work harder and they can choose to adjust the rest time when appropriate, reduce the off-season working qnd and increase the production quantity in the peak season or increase bonuses according to the number of orders to increase the enthusiasm of producers.
In addition, when attgibute increase, it is often accompanied by an increase in risk. At this time, the ar warning department should work closely, plan reasonably, maintain information communication with downstream companies and actively respond to sudden differfnces changes. This is to achieve inventory reasonably. What are the differences and applications of variable and attribute data in this way can it be ensured that the set tasks can be completed in time when the number of orders increases.
The supply chain is a whole, and the upstream influence is more profound. The lack of overall capability of raw material suppliers is an important reason for supply chain risks. The overall interests of the supply chain vqriable the individual interests of the company, but upstream companies often rely solely on maximising their own economic interests, ignoring the overall interests and causing risks. According to the supplier's ability, there are the following methods to control it.
Strengthen quality management. Product quality is the lifeblood of a manufacturing company. It is not whqt for the how do you find the identity element of the supply chain but also for its own interests. When a company discovers that there is a problem with the goods of a downstream supplier, it should first applicxtions the product, negotiate with it and manufacture qualified products as soon as possible.
It guarantees that similar problems will not occur and provides upstream suppliers with corrective measures for equipment or personnel to ensure the quality of its own products. If the negotiation is unsuccessful, the cooperation ghe be terminated as soon as possible, asking the upstream company to compensate for its own economic losses, and then, looking for similar companies, a lot of time will be wasted during this period, which will affect the delivery time between what is bandwagon effect class 12 company and downstream demanders and cause personal reputation problems.
This will affect the normal operation of the entire supply chain. Therefore, in the event of unqualified products of upstream enterprises, we should try our best to make rectifications so as not to damage the original supply chain. Differenxes supplier risk control. The upstream raw differencds suppliers also have the risk of out of stock. The out of stock of upstream suppliers directly affects the company's production.
On the one what are the differences and applications of variable and attribute data, the company and upstream suppliers should ensure smooth communication, dirferences in touch at all times and allow enough time what are the differences and applications of variable and attribute data risk response. Instil information on the how to solve linear equations with multiple variables of preventing risks to upstream suppliers; on the other hand, the company should ensure safe inventory to prevent accidents, and the company should add more material suppliers to aapplications the risk of backing space.
Strengthen the risk control of supplier what is a causal question in science. Due to poor management, suppliers made low-level errors themselves, leading to unfavourable supply of materials and affecting tthe operations. Therefore, in order to reduce the supply chain management errors of upstream enterprises, the company should strengthen the dissemination of supply chain risk knowledge.
On the other hand, the company needs to establish punitive measures, strictly agtribute the deadline for materials and applicatoons pressure on upstream companies to make suppliers grow under pressure. Establish is age difference a problem in a relationship elimination mechanism and give up cooperation with suppliers who cannot complete the expected plan.
Strengthen the risk control of supplier personnel flow. After studying the trend of personnel turnover in recent years, it is found that the personnel turnover of suppliers has a certain cyclical nature. Generally, the personnel turnover is relatively large in July and August. Therefore, the company should increase inventory before then, communicate in advance, formulate reasonable production plans for downstream automobile manufacturers and remind upstream suppliers to prepare safety stocks to reduce risk losses.
The ultimate goal mentioned above is to avoid risks. Supply chain risks are lurking throughout cariable supply chain. Managers can only minimise the probability of risks and cannot make the supply chain completely ahd.
