Selecting suitable key supplier for core components during smart complex equipment central-private enterprises collaborative development process:from two different forms of evaluation information and matching perspective

With the development of central-private enterprises integration,selecting suitable key suppliers are able to provide core components for smart complex equipment.We consider selecting suitable key suppliers from matching perspective,for it not only satisfies natural development of smart complex equipment,it is also a good implementation of equipment project in central-private enterprises integration context.In in this paper,we carry out two parts of research,one is evaluation attributes based on comprehensive analysis,and the other is matching process between key suppliers and core components based on the matching attribute.In practical analysis process,we employ comprehensive evaluated analysis methods to acquire relevant attributes for the matching process that follows.In the analysis process,we adopt entropy-maximum deviation method(MDM)-decision-making trial and evaluation laboratory(DEMATEL)-technique for order preference by similarity to an ideal solution(TOPSIS)to obtain a comprehensive analysis.The entropy-MDM is applied to get weight value,DEMATEL is utilized to obtain internal relations,and TOPSIS is adopted to get ideal evaluated solution.We consider aggregating two types of evaluation information according to similarities of smart complex equipment based on the combination between geometric mean and arithmetic mean.Moreover,based on the aforementioned attributes and generalized power Heronian mean operator,we aggregate preference information to acquire relevant satisfaction degree,then combine the constructed matching model to get suitable key supplier.Through comprehensive analysis of selecting suitable suppliers,we know that two-sided matching and information aggregation can provide more research perspectives for smart complex equipment.Through analysis for relevant factors,we find that leading role and service level are also significant for the smart complex equipment development process.

Study on Evaluation of Supplier's Quality Assurance System

To be a worldwide competitor, enterprise needs to e va luate and select its supplier carefully. Generally, to evaluate a supplier, the evaluating effort is focused on the purchase price, delivery time, product quali ty, etc. The vendors’ quality assurance is seldom considered. However, it reflec ts the ability that a vendor can provide high quality but low cost products cont inuously and stably. In this paper, with the study on evaluation of supplier’s q uality assurance system, a set of methods and indices to supplier’s quality assu rance evaluation is introduced. The indices construct an index system, which is based on the ISO9000 series standards. According to the problem’s character and the requirement of evaluation, all the evaluation indices are set off to three k inds: general index, functional index and protective index. And the evaluation m ethod combines quantitative analysis with qualitative analysis. Firstly, a sensi tive factor model is constructed to estimate the contribution of factors that ha ve key effect on synthetic evaluation in supplier’s quality system. Then, those suppliers having low evaluating value are rejected. Secondly, fuzzy logic is int roduced to evaluate other suppliers synthetically. The rest suppliers are compar able. So, supplier’s quality assurance system can be evaluated in quantity. Afte r unification works, the evaluated suppliers can be ranked. And the best vendor can be selected out intuitively.

Supplier Evaluation Model Based on Fuzzy Measures and Choquet Integral

To identify interactions among evaluation criteria and describe their importance,a new identification method making use of a fuzzy measure is presented.The relative weight and interaction degree of every evaluation criteria pair are obtained by using the diamond pairwise comparison method.Based on comparison results,the maximum eigenvector method of analytic hierarchy process （AHP）,the hierarchical clustering method,and the phi（s） transformation are utilized to generate values of the fuzzy measure for each subset of the evaluation criterion set.Overall evaluation on each supplier is aggregated by Choquet integral with respect to the fuzzy measure.Finally,an illustrative example demonstrates the practical feasibility and validity of the proposed method.

Selection Model in Buyer-Supplier Relationships

This paper proposes a new method of selecting appropriate buyer supplier relationships (BSR) for specific projects. Because it is almost impossible in reality to establish mathematical relationships between the BSR attributes and the factors of a project, the concept of relationship indices (RI) is introduced to quantify such BSR which are in turn established through design of experiments. Based on the experimental results, the contributions of project factors, known as factors relationship worths (RW...

Web-based supplier relationship framework using agent systems

In order to enable both manufacturers and suppliers to be profitable on today’s highly competitive markets, manufacturers and suppliers must be quick in selecting best partners establishing strategic relationship, and collaborating with each other so that they can satisfy the changing competitive manufacturing requirements. A web-based supplier relationships (SR) framework is therfore proposed using multi-agent systems and linear programming technique to reduce supply cost, increase flexibility and shorten response time. Web-based SR approach is an ideal platform for information exchange that helps buyers and suppliers to maintain the availability of materials in the right quantity, at the right place, and at the right time, and keep the customer-supplier relationship more transparent. A multi-agent system prototype was implemented by simulation, which shows the feasibility of the proposed architecture.

Lean Construction in Supply Chain Management： Supplier and Buyer Relationship in Social Housing

To the accomplishment of this article, we have chosen, as a case study, a small Goiana construction company that acted in the market of social housing. The main goal of this work is to analyze the fundamental aspects related to the management of the flow of supplies in civil construction to achieve a greater streamlining of logistic processes involved in supplying material. A checklist was developed for the purpose of data collection, and it was applied by means of an interview with the person in charge of the purchase department of the enterprise. In addition, this person is the engineer of the site. Taking into account the exploratory feature of this research, the construction site was visited so that some issues, such as quality aspects, losses, cleanliness and organization, could be observed. This on-site data collection visit was carried out through visual analyses and photographs. The obtained results were subdivided into a quantitative and a qualitative analysis. In this way, it was possible to see that the production process still has many phases to be improved. What is more, it was possible to see that the construction company knows its flaws and necessities to improve its processes although the final result does not have the expected quality. Being aware of this need for improvement, the construction company aims at having an affordable price product to the target public, especially when it is associated to an image that shows quality.

Vertical Spillover Effects of Multinationals on Chinese Domestic Firms via Supplier-Customer Relationships

Foreign direct investment （FDI） can benefit domestic firms in the host country. Using firm- level data for China, we find statistically positive vertical spillover effects of multinational enterprises on the performance of domestic firms through backward and forward supplier- customer relationships. The spillover effects are mainly from large multinational enterprises and are greater for state-owned firms and in poor regions. Our results are robust for both parametric regression and nonparametric matching techniques. Our findings have strong policy implications： while regulations relating to building business relationships with domestic firms when seeking foreign direct investment should be established, such policies should be aimed at private firms, big multinationals and less developed regions.

企业财务困境与供应商稳定性的关系

产业链供应链安全是国家安全的重要组成部分,如何维护供应链稳定发展历来备受关注。以不同产权性质和不同危机来源为标准,将陷入财务困境的上市公司分为四类,然后根据类别,选取4家上市公司作为样本代表,探究企业财务困境与供应商稳定性的关系。研究发现,企业陷入财务困境后,供应商的稳定性通常会下降。当危机来源相同时,国有控股企业的供应商稳定性低于民营企业;当产权性质相同时,来源于整个行业的危机对企业供应商稳定性的影响高于来源于自身经营危机的影响。进一步研究发现,与困境企业有着共同投资项目、合作时间较长、存在关联关系的供应商,继续保持合作的倾向较高。在企业度过财务困境后,供应商稳定性受企业发展战略是否变动、经营区域布局是否变动、是否有共患难经历三个因素的影响较大。鉴于企业陷入财务困境是导致供应商不稳定的重要因素,必须谨防企业大面积陷入财务困境引发的供应链中断风险,加强供应链企业间的合作;危机过后企业经营稳定性能够强化供应链稳定性,因此危机过后不宜对企业的发展战略和经营区域布局进行大调整。
