It is of crucial importance for any construction company to be able to deal successfully with various bidding situations. This paper offers a multi-criterion evaluation approach for contractors to selecting which contracts to bid for. As is generally accepted, bidding decisions can be divided into two consequent stages as bid/no bid and mark-up decisions, and the paper is of no exception. In bid/no...
Based on the analysis of the development of Guangzhou economy and logistics parks, this paper introduces the BOT project mode of Guangzhou logistics parks. Based on the BOT, this paper analyzes the risks which the Guangzhou logistics parks meet, and designs an evaluation system. And then, through grid method and fuzzy Borda number analytical method, this paper analyzes the BOT project risks of Guangzhou...
In this paper, we combine GRA (grey relation analysis) with fuzzy TOPSIS to evaluate performance of iron and steel companies. In the empirical study of a Chinese iron and steel company, we apply grey relation analysis to find representative indices. Then fuzzy TOPSIS is utilized to evaluate the value creation strategy performance of the company. By the evaluation, we can get the conclusion that the...
As the Internet is getting more and more popular, the types of operations of e-commerce update rapidly. Many entrepreneurs build up on-line stores to get greater profits. Thus, the evaluation of network marketing has become an important research topic. In the process of evaluation, because of the differences in operation styles and the fuzziness of the experts' subjective judgment, the evaluation...
The evaluation process takes on a broader and more complex characteristic with the growth of interorganizational projects, programs, and technologies. Facing imprecise or fuzziness factors, most decision making method uses fuzzy analytic hierarchy process (Fuzzy AHP) method. However, the numbers of comparisons increases with the number of criteria, the decision maker judgments will most likely be...
A novel score function is presented by taking into account the expectation of the hesitancy degree of interval-valued intuitionistic fuzzy sets (IVIFSs). And a deviation function is defined considering the variance of the hesitancy degree of IVIFSs. A new method for ranking interval-valued intuitionistic fuzzy numbers is then established based on the score function and deviation function. The proposed...
Outsourcing logistics business can improve core competition of enterprise. So it is of vital importance to evaluate logistics service quality. Fuzzy Comprehensive Evaluation Method is an effective method. In this paper, we take logistics company M as studying object. We construct evaluation index and mathematic model. By quantifying index and calculating, we conclude that the service quality of logistics...
The text puts forward improved fuzzy relation composition: weighted fuzzy relation composition, then discusses and analyses its application in fuzzy synthetic evaluation.
This paper uses a fuzzy data warehouse approach to support the fuzzy analysis of the customer performance measurement. A data warehouse concept supporting fuzzy dimensions and fuzzy facts is described. The potential of the fuzzy data warehouse approach is illustrated using a concrete example of customer performance measurements of a hearing instrument manufacturer. The example discusses the creation...
Ranking fuzzy numbers is important for decision-making problems in a fuzzy environment, since the measurements are imprecise in nature. In this paper, the angle of triangular and trapezoidal fuzzy number, the fuzzy spread of triangular and trapezoidal fuzzy number a redefined respectively, which are important indices for ranking fuzzy numbers. Using these new ranking indices, one new method of ranking...
The architectural design service, a knowledge intensive industry, expands rapidly in china. The evaluation of architectural design services is necessary for managers in architectural design service industry to upgrade their service level and for consumers who purchase the services to select an architectural design vendor. However, the evaluation of architectural design services is a multiple-criteria...
An ERP (enterprise resource planning) ISV (independent software vender) investment decision model is considered in fuzzy decision environment. The size of the market, the sensitivity of demand to the price and quality, and fixed cost are treated as fuzzy variables. The Graded Mean Integration Representation method is used to solve the fuzzy profit, and equilibrium price, quality, demand, total cost...
Private equity investment decision-making is the most important issue in private equity investment selection. There are higher uncertainty and complexity in private equity investment decision-making process. This paper analysis these uncertain risk in private equity investment decision-making base the previous studies. Attributed the private equity candidate firms' select to fuzzy optimal decision-making...
Trust is a fundamental concern in large-scale open distributed systems such as multi-agent systems. It lies at the core of all interactions between the entities that have to operate in such uncertain and constantly changing environments. In this paper, an approach is developed for the evaluation of trust using fuzzy reasoning. The approach takes different trust sources into account, thereby minimizing...
In the system of highly globalized world economy, corporate social responsibility has become main trends and methods, which made the corporate sustainable operation. Modern financial analysis, however, always based on the analysis of economic responsibility, ignored the legal responsibility, ecological responsibility and ethical responsibility. Such neglect has made not only the outcome of decision-making...
Nowadays, liner shipping has become a constant operation model for shipping companies, and scheduling is an important issue for operation. It is well-known that a nice plan for route of container ships will bring long-term profit to companies. In the earlier works, the market demand is assumed to be crisp. However, the market demand could be uncertain in real world. Fuzzy sets theory is frequently...
The aim of this paper is to detect incoherences in concepts, ideas, values, and others contained in technical document corpora. The way in which document collections are generated, modified or updated generates problems and mistakes in the information coherency, leading to legal, economic and social problems. A solution based on summarization, matching and neuro-fuzzy systems is proposed to dealt...
Transport logistics and fleet management problems often fall into one class of the optimization problems. Finding an optimal set of routes for a group of vehicles in the transportation network under defined constraints is known as the Vehicle Routing Problem (VRP). In this paper, we propose a novel hybrid uncertain approach, in which first considers a capacitated VRP whose demands are assumed to be...
In this paper, we develop the multi-products multi-constraints newsboy problem with fuzzy demands considering the total discount situation. Since the demands of products are often fuzzy in the real world, the profit of the newsboy is fuzzy too. A new model is presented for multi-products multi-constraints newsboy problem in fuzzy environment (FM-PM-CNP). The objective function of proposed model is...
Outsourcing is an increasingly important issue pursued by corporations seeking improved efficiency. Logistics outsourcing or third-party logistics (3PL) involves the use of external companies to perform some or all of the firm's logistics activities. In this paper, by analyzing the feature and role of third-party logistics, for 3PL provider selection, we put forward basic principle of data integration,...
