This study examines the impact of supply chain integration (SCI)dimensions on competitive capabilities. For this purpose, therelationship between dimensions of SCI (internal integration andexternal integration including supplier integration and customerintegration) and competitive capabilities (cost, quality, delivery,product innovation) were examined using a conceptual model. Thedata was collected from top managers of 44 medium and largeenterprises of Mashhad Food and Beverages Industries by surveyapproach. In this study, partial least squares method by Smart plssoftware and Hulland procedures are utilized to evaluate themeasurement and structural models. The results indicated that internalintegration is a prerequisite for external integration. The study alsorevealed that, internal integration and external integration havepositive impact on improvement of firms’ competitive capabilities. Itwas further noticed that, internal integration improves competitivecapabilities through external integration

Nowadays one of the most important decisions for the companies iswhether to outsource a part of the organizations’ value chain or not.Some studies show that majority of them, consider outsourcing as acost reduction approach, not as a strategic decision. Some researcheshave paid attention to this concept. This paper presents a decisionmaking framework which consists of five criteria, thirty scenarios andeight strategies. According to this framework, activities outsourcingdecisions can be made. This framework has been applied for thirtythree manufacturing sets of Samand automotive. The suggested optionfor twenty six of them is “Supplier Development and Outsourcing”,for five sets is “Insourcing”. “Partial Outsourcing” is suggested forone set and “Spin off” for another one.

Knowledge has widely been acknowledged as one of the mostimportant factors for corporate competitiveness, and we havewitnessed an explosion of IT solutions claiming to provide support forknowledge management. Due to the rapid development of knowledgeand information technology (IT), business environments have becomemuch more complicated. In order to cope with ensuing complications,enterprises ought to incessantly innovate; otherwise, it will be verydifficult for them to survive in the marketplace. Hence, IT can help afirm aiming to gain a competitive advantage. In addition, many studieshave argued that business value comes mainly from intangible assets,such as knowledge. Thus, knowledge workers will be able to replaceclerical workers as the new mainstream of manpower resources, afield in which the development of IT is the major force for change inknowledge management system (KMS). Therefore, based on thedefinition of the six gaps in KMS, this study explores the role andeffect of IT in the implementation of KMS in the IK company. EachGap is discussed and the results of an empirical assessment employedto evaluate them are then reported in order to identify each gap'ssituation in a company and which one has to be improved first.moreover, relationships between KMS and IT are analyzed anddemonstrated by means of the literature reviews, expert interviews andquestionnaire analyses. Furthermore, this study discusses how toenhance the effectiveness and efficiency of implementing KMSthrough appropriate IT tools.

This research study aims at using Data Mining and Fuzzy Logicapproaches to classify the credit scoring of banking system applicantsas to cover uncertainties and ambiguity connected with applicantclasses and also variables that affect their behavior.The methodology, according to a standard Data Mining process, is tocollect and refine the client data, then those variables which are inlinguistic forms are converted to fuzzy variables under the supervisionof banking experts and final data are modeled using Fuzzy DecisionTree, subsequently. The unfuzzy data are also modeled using the otheralgorithms.The results of the study suggest that as far as client distinctionaccuracy is concerned Fuzzy Decision Tree produces better resultscompared to Traditional Trees, Neural Networks, and statisticalprocedures such as Logistic Regression and Bayesian Network.However, it is not as accurate as Support Vector Machine and GeneticTree. On the other hand, Fuzzy Decision Tree technique has gainedbetter prediction than prediction performance of bank credit scoringexperts.

In this research, exploratory mixed research are used and implementedat two stages. At first stage, two questionnaires are designed. Based onCambridge University’s Model, responsiveness of Almas-e-Kavir andEhsan Industrial Group are surveyed and analyzed that are done bycomparative-theoretical case study. A questionnaire is designedaccording to the comparative-theoretical case study that determinesresponsiveness’s degree of ceramic tile industry’s companies. At thesame time, literature reviews of knowledge management enablers aredone and a questionnaire is designed. At the second stage, twoquestionnaires are distributed and after gathering them, data areanalyzed. In this stage, questionnaire of knowledge managementenablers are validated by confirmatory factor analysis. Then, affect ofknowledge management enablers on responsiveness are analyzed bydiscriminate analysis. Responsiveness at manufacturing systems isability to achieving operational objective with internal and externaldisturbances. Results are shown that infrastructures of knowledgemanagement have more effect on responsiveness than people,strategy, and processes

The objective of this study is to investigate the impact of industryconcentration on the average stock returns, and proposing a model toexplain this relationship. Explanatory variables are Herfindahl-Hirschman Index of industry concentration, industry size (marketequity), book-to-market ratio, leverage, past 1-year's industry returnand systematic risk (beta); also the industry average return is taken asthe dependent variable. With respect to the concentration index is anindustry specific, all of the dependent and independent variables inthis research are evaluated in industry level. The study covers 1380-1386 and uses 31 manufacturing industry-year observations. Forexamine the research hypothesizes, we use the Panel Data techniquewith Fixed Effect and Generalized Least Squares (GLS) method.Results indicate that in Tehran Securities Exchange there is significantrelationship between industry concentration, size, book-to-marketratio, systematic risk and average stock returns. On the other hand,leverage and past 1-year's industry returns are not associated withannual industry returns.

Now days, many internal banks of country experiment a kind of creditrisk, where can enumerate increasing non-performing loans of thebanks and not repayment problem of the central bank debts as itsresults. Therefore, to establish a system of credit risk management isnecessary and essential. The Five Cs of credit valid system is one ofthe rating systems of customers where can be considered for creditrisk management. In the other hand, existence of a suitable tool toestablish this system is necessary. The VIKOR method is one theefficient tools to rate feasible alternatives where can be used for ratingcredit of customers. In this paper, a method of advanced VIKOR willbe proposed which can present the optimal values of attributespreference weights in decision making process. To illustrate themethod proposed, a numerical example will be presented about creditrating problem of banks customers and the best feasible alternative togive facilities will be determined

The significant role of investment in the process of societies’economic growth and development is highlighted in most theories oneconomic growth and development. Taking into account the shortageof investment sources and the necessity of optimal allocation of thesesources for promoting economic growth, it is necessary to rightlyidentify the relative advantages of a country as regards the allocationof investment sources and also direct investment sources in mostproductive and efficient sectors in order to provide for efficient use oflimited sources to accelerate economic growth. Thus, it is muchnecessary to use the scientific methods of economic engineering andeconomic evaluation of projects to economically and financiallyevaluate investment projects. This descriptive, analytic and appliedstudy evaluates economic indicators of investment in Tarom (locatedin Zanjan Province) as an international recreational-tourist town viadifferent criteria of economic and financial evaluation and the use ofCOMFAR (A computer software for simulating the financial andeconomic situation of investment projects). The results indicated thatconducting the project of Tarom Recreational-Tourist Town has nojustification in terms of indicators of financial and economicevaluation.
