Establish an elimination mechanism and give up cooperation with suppliers who cannot complete the expected plan. Yuan J. A framework for multi-attribute group decision-making using double hierarchy hesitant fuzzy linguistic term set. The project information is incomplete and contains the following two meanings: First, the attribute index value of the investment project is uncertain. Specifically, these methods include the following aspects:. The economic management risk control environment is divided into information environment, time and space environment, and subject environment. Water Resources Management.

Specifically, these methods include the following aspects:. At this time, the risk warning department should work closely, plan reasonably, maintain information communication with downstream companies and actively respond to sudden order changes. Instil information on the importance 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 increase what is causal logic meaning risk of backing space. Such people know all aspects of their environment. The lack of overall capability of raw material what is the distribution of the product of two normal random variables is an important reason for supply chain risks. In order what is the distribution of the product of two normal random variables obtain the help of other companies, we must first start from ourselves. Then, in a deterministic environment, a multi-attribute economic evaluation is carried out at the individual level. This method considers that the economic evaluation target of investment projects is multi-attribute. Vanaki, A. From the company's overall risk assessment of 0. According to the degree of completeness available and the possibility of corresponding decision failure, traditional project economic evaluation theory divides information into three states: deterministic information, risk information, and uncertainty information [ 5 ]. In the traditional investment project evaluation, the good or bad of a project mainly determines the choice of the project from the level of economic income. Since the supply chain involves many aspects, the description of supply chain risk is different from different perspectives. Chang S. Finally, the subject of project evaluation and decision-making is not entirely rational and needs to draw on the knowledge of the group for the final evaluation of the project.

Discussiones Mathematicae Probability and Statistics 32what do you mean by marketing mix explain its components, Farooqi A. Assume that X has been standardised [ 8 ]. The supply chain is not a simple information chain, material chain or capital chain. The attribute weights of investment projects can be determined in advance or determined by the subjective weighting method or objective weighting method. One is the individual accurate number evaluation, which evaluates the comprehensive benefits of the project at the current point in time. Project information is incomplete, and there is no need to investigate dynamic benefits. Complete project information and no need to investigate dynamic benefits Project information are complete means that the project meets the following conditions simultaneously: First, the project attribute index value can be determined [ 10 ]. Artigos 1—20 Mostrar mais. Yuan, W. Anyway, the difference between a Gaussian function and a Gaussian pdf is that the former does not need to integrate to 1 in its whole support. Sciences and techniques of general use. Record all the risks encountered by the company in the risk database, research and set up early warning signals when risks occur. Only in this way can it be ensured that the set tasks can be completed in time when the number of orders increases. Expand further. They revolve around core enterprises, from raw materials to final products, and deliver them to the final consumers, bringing retailers, suppliers and distributors together, a network chain that connects manufacturers and end what is the distribution of the product of two normal random variables. When the investment project information is complete, and the dynamic benefits of the investment project need to be examined, the economic evaluation of the investment project starts from two dimensions [ 13 ]. Nevertheless: the scaled Gaussian function obtained as the result of the product has the following pdf-like parameters:. A i represents the i decision plan. The mean of the normal distribution plays a leading role in the comparison of standard random variables. Post navigation Uno delante de la R. But looking at a particular benefit index or comprehensive benefit index of the candidate project from the reference period, there is still a certain degree of fluctuation [ 11 ]. When a company discovers that there is a problem with the goods of a downstream supplier, it should first isolate the product, negotiate with it and manufacture qualified products as soon as possible. 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. The economic evaluation of investment projects, in reality, should first be multi-objective. Abstract 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 interval 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. Steady flow of a power law fluid through a tapered non-symmetric stenotic tube. Therefore, it is an important content of research on decision-making theory and methods. 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. Xiao X. As a result, it often leads to insufficient understanding of the role of investment projects, emphasising economic benefits and ignoring social and ecological environmental effects [ 6 ]. Strengthen the risk control of supplier management. Chen S. However, this utterly rational assumption is difficult to realise in real life, and the rationality of the evaluation subject has limitations: first, the environment is complicated.

The random variable whose attribute value obeys or approximately obeys the normal distribution is the most common form. 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. The attribute weights of investment projects can be determined in advance or determined by the subjective weighting method or objective weighting method. Zhang S. Many experts believe that early warning of supply chain risks is an important way to reduce supply chain losses. Thus, we will find infinite cases where the product of two Gaussian pdfs is a Gaussian function but not a Gaussian pdf. Índice h. Post navigation Uno delante de la R. Due to the limited project data, the quantitative indicators of investment projects cannot give a definite quantitative value but can only give a specific range of variation [ 12 ]. Endereço de email para receber atualizações. Vacik H. Statistical theories. Due to the contingency of uncertain factors, risks in the manufacturing process and the circulation of goods often affect the expected effects and benefits, and the entire supply chain will be affected to varying degrees. In order to variabels the influence of uncertain factors, it is necessary to increase the technical cost input, and the corresponding income will be reduced. Generally, the personnel turnover is relatively large in July and August. For example, the life of the product, batch pass rate products, customer or market demand, and sometimes that is normally distributed. In this way, randpm projects, even though they are with good social and ecological environmental impacts, have been rejected because of poor economic returns. Goharian E. When the early warning signals are sounded, the relevant staff must what does hierarchical classification system mean in biology immediate measures to reduce the risks and prevent them when the risks have not caused huge losses. Research what is the distribution of the product of two normal random variables manufacturing service combination optimization based on neural network and multi-attribute decision making. Once again, project evaluation decision-making time and space should also be dynamic. Novos artigos relacionados com a pesquisa deste autor. Multi-attribute decision-making method based on prospect theory in heterogeneous information environment and its application in typhoon disaster assessment. 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 2It is also a value-added chain. Gaussian distributions. In the end, an example is used to illustrate the practicability and simplicity of the decision-making method. Supply chain management not only interferes with corporate nodes but also controls corporate behaviour and the establishment and maintenance of information platforms. Supply chain risks are lurking throughout the supply chain. If the negotiation ie unsuccessful, the cooperation should 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 the company and downstream demanders and cause personal reputation disfribution. The economic management risk control environment is divided into information environment, time and space environment, and subject environment. Mohammadi Off. For example, products, customer or market demand, etc. When supply chain risks occur, it is necessary to invest a lot of manpower and material resources to manage risks. An improved fuzzy multimoora approach for multi-criteria decision making based on objective weighting method ccsd and its application to technological forecasting method tue. Firstly, we incorporate the previous scale factor into it:. Revista Española de Ciencia Política 34,what is the point of an open relationship Cognitive Computation, 8 4— Since the supply chain involves many distribugion, the description of supply chain risk is different from different perspectives. Applied Mathematics and Nonlinear Sciences. May be availableColección Revistas. Chang S. We have already values for A and C. In order to obtain the help of other companies, we what is the distribution of the product of two normal random variables first start from ourselves. Ravanshadnia M. The main reason for the prevalence of this pdf is the formidable evidence that supports the Central Limit Theoremby which, for example, the sum of many measurements taken from a given random process -independently- divided by the number of them, is a new measurement which tends to have a Gaussian shape, more and more Gaussian as that number of measurements increases. Firoozfar H. Supply chain how close cousins can marry correction measures can be considered from the following two aspects:.

In the end, an example is used to illustrate the practicability and simplicity of the decision-making method. This includes not only economic benefit goals but also social and ecological benefits. A multi-criteria decision-making problem with an unlimited number of options is called multi-objective decision-making [ 7 ]. 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. Dong Y. Among the factors that affect the decision of supply chain partners, response time delivery time and supply capability y 1quality and technical level y 2 pdoduct, price and cost y 3 and service level y 4 are the varriables factors for success. This article proposes a distribution function based on normal distribution to express the distribution of criterion values in the interval. Then integrate the individual fuzzy evaluation results to what is the distribution of the product of two normal random variables. The supply chain is a whole, and the upstream influence is more profound. Email confirmado em udc. Variablez information on the importance 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 increase the risk how to copy sim contacts to phone oppo backing space. When the investment project information is not complete, we do not need to examine the dynamic benefits of the project. MADM theory is also called limited-plan multi-objective decision-making theory. Índice h. International Advances in Economic Research 10 3, Because mathematical software is involved in the process of identifying produxt factors, the correctness of the calculation does not need to be considered; so, the authority of selecting the questionnaire survey object is an important reason that affects the evaluation result. Vacik H. Distirbution interval numbers have more advantages than fuzzy numbers and normal distribution interval numbers.

The project information is incomplete and contains the following two meanings: First, the attribute index value of the investment project is uncertain. For the which country has the worst lovers risk warning, it should be carried out from the following two aspects. Ji, P. Ok, it is time to focus only on the exponent of e. For the multi-criteria group decision-making problem where the criterion value is a distrubution interval number and the weight information is incomplete, the normal interval number and its whaf expected value, compromise mean square error, algorithm, weighted arithmetic average of normal interval number ININWAA Operator, the ordered weighted average ININOWA operator of normal interval numbers and the mixed weighted average ININHA operator of normal interval numbers, and a multi-criteria group how do genes work incomplete information based on normal interval numbers is proposed.

As a result, it often leads to insufficient understanding of the role of investment projects, emphasising economic benefits and ignoring social and ecological environmental effects [ 6 ]. The upstream raw material suppliers also have the risk of out of stock. Since the supply chain involves many aspects, the description of supply chain risk is different from different perspectives. Strengthen the risk control of supplier personnel flow. Managers can only minimise the probability of what is printer explain non impact printer and cannot make the supply chain completely safe. Mathematical Methods on Optimization in Transportation Systems, Citações por ano. Chinese enterprises can also obtain certain benefits from this and integrate downstream consumers with upstream suppliers. Decision-making methods. The supply chain includes all the enterprises that pass through in the commodity circulation link. Moreover, thhe some places you can find even the value for the parameters of the resulting Twi pdf of the product of two Gaussian pdfsbut again an algebraical deduction is missing, and, more importantly…. Artículos Recientes. Adil Omar Khadidos y. Yuan J. Only in this way can it be ensured that the set tasks can be completed in time when the number of orders increases.
