In this paper, a method based on Bayes theory is presented aiming at the problems of small sample maintainability verification for the shrapnel emitter. And Posterior Probability Ratio Test of maintainability index verification in the logarithmic normal distribution is discussed in detail. By analyzing the test data of the shrapnel emitter, it is proved that the method is effective and reasonable...
The selection of suppliers is an important part of enterprise strategy, so it is very important to evaluate suppliers using proper methods. This paper firstly constructs comparison matrix using DEA, then assesses the alternatives using AHP. In this method the known data is fully used and the influence of personal factor is avoided. Finally an example is used to prove the method effective.
Evaluation on the credit rating of suppliers is a scientific work involving management, statistics, psychology and other disciplines and fields. Existing evaluation methods are most qualitative analysis methods, with a certain degree of subjectivity and one-sidedness, not fully and accurately. Using data mining technology based on entropy to mine knowledge information about object classification hidden...
The bounded rationality of human behaviors in decision making can be characterized by an S-shaped utility function. We discuss a newsvendor problem with an S-shaped utility. It is shown that the expected utility of the final wealth is unimodal, based on which an optimal policy can be obtained. The impact of initial wealth is investigated and some structural properties of the optimal policy are given...
The problem of resource service optimal-selection and composition (RSOSC) in manufacturing grid (MGrid) system is proposed. Based on the authors' previous work, a framework for addressing RSOSC problem in MGrid system is presented. The framework consists of five layers: (1) task layer-responsible for MGrid task decomposition, (2) resource service match and search layer-responsible for searching the...
As customer demands become more and more individualised, also the process of providing estimates and tendering offers is becoming increasingly complicated. In the future, apart from technological feasibility, order placement will to a great extent depend on the bidder's ability to respond to individual customer requests. Automated pre-calculation of production times and costs is thus becoming more...
Failure Mode and Effect Analysis (FMEA) is a popular problem prevention methodology. It utilizes a Risk Priority Number (RPN) model to evaluate the risk associated to each failure mode. The conventional RPN model is simple, but, its accuracy is argued. A fuzzy RPN model is proposed as an alternative to the conventional RPN. The fuzzy RPN model allows the relation between the RPN score and Severity,...
This paper proposes a fuzzy TOPSIS method based on Vague sets. The relationship between the fuzzy TOPSIS method and fuzzy weighted average (FWA) is also discussed. An example including an application to IT project risk assessment is investigated using the proposed fuzzy TOPSIS method. It is shown that the proposed fuzzy TOPSIS method performs better than the other fuzzy versions of the TOPSIS method.
We consider modeling of manufacturing enterprises as networks which process, store, and transport materials between enterprise nodes in order to feed customer demand. Each node within the network is represented as a dynamic model with associated costs of production and inventory. Examples of disruptions for such an enterprise could be weather events, material shortages, equipment disasters, or labor...
Process capability indices (PCIs) are powerful means of studying the process ability for manufacturing a product that meets specifications. However, available methods of Process Capability index evaluation are only for machining process. There are no methods for comprehensive evaluation of total producing process capability. In this paper, a comprehensive evaluation model of entire producing process...
Most partners in a high-tech virtual enterprise (HTVE) readily incline to reduce their innovation efforts for worrying about irrevocable loses resulted from unpredictable risks. Partners should be motivated by obtaining deserved compensation fairly based on their contribution. The contribution of a partner is obviously relevant to its costs exhausted during cooperation process, which is difficult...
Similar to open loop supply chain, due to asymmetric information, there is the moral hazard and incentive conflict in closed loop supply chains, which may lead to bad performance and decrease profit. To deal with this problem, in the context of a single-manufacturer and single-retailer closed loop supply chain, the game between manufacturer and retailer was studied from the point of principal-agency...
Price characteristics of radio components are researched. The changes of their parameters during radio device life cycle are considered. The minimal cost and cost/quality strategies are analyzed. If output function deviations, restrictions of total cost of radio components, the list radio components are preset the cost/quality strategy is used. The efficiency of different strategies is compared.
This paper presents a new method, one-step QFD (3*HOQ), to overcome the complexity of QFD practices in new product development. In the method, marketing people, design engineers, and manufacturing staff concurrently work together on finding customer requirements and transforming to product functions, product specifications, and functional modules, thus reducing misalignment between the cascade process...
Aviation subcontract production (SP), the particular manufacturing mode of aeronautical manufacturing, is an important instrumentality participated in market competition, but the key step formed the SP alliance is the partner selection and evaluation. In order to improve the ability to solve partner selection and evaluation problems, such as increasing alternatives, increasing info fuzziness, and...
This paper analyzed deep-seated problems which existed during the information technology application in the manufacturing enterprises, and explored the relationship between the application of information system and the promotion of management system. By studying the preconditions of the application of information system and the guarantees which the industrial engineering offers in the manufacturing...
The purpose of this paper is to study the operational competitiveness of Chinese aeronautics and astronautics manufacturing companies (CAAMC) by analyzing the case CAAMC in a global manufacturing strategies (GMSS) database. Analytical models are used to analyze the operational competitiveness of the case CAAMC based on the weights of the multi-criteria manufacturing strategies. The results show quality...
Product lifecycle management aims at providing a collaboration platform for integrated product team and partners in supply chain through integrating different stages in product lifecycle. In this paper, function and architecture of product lifecycle management system are analyzed first. Then system model is established from point of view of application and development. Product view and process view...
Modern manufacturing environments are complicating and evolving, which is random fuzzy in nature, but quality has always been the domain of accurate science, and the traditional methods for assessing the capability of manufacturing processes are dealing with precise quality, so the introduction of fuzzy quality is an overall comprehensive reflection of precise quality. Instead of precise quality,...
A novel optimization design method for CWSP is presented to bring large tolerance by enlarging its performance margin. The proposed OFPD can be used in local optimization procedures and as well as in global ones to design an optimized CWSP.
