Nowadays, many organizations face with increasing competition and
uncertainty environment, supported by innovating technologies and the
changing needs of customers. In this environment, past methods in supply
chain loose their ability. One efficient method in this regard is agility. Thus,
for modeling the agility of supply chain, a wide range of research was done
in the literature. The results of this research and interview by experts found
11 critical success factors of agile supply chain. Then these factors were
entered into a questionnaire and the experts of Zobahan Co Supply Chain
were asked to fill in it. The obtained results were analyzed by interpretive
structural modeling and the Correlations between those factors were
determined. The attained correlations indicated that development of the
employees’ skills, employment of IT and programming are the basics of
agility in supply chain. This model would help the supply chain managers in
strategic planning for improving the agility of supply chain.

The main purpose of this research is to provide a good insight into the use of
analytic network process (ANP) that is a multiple criteria decision-making
methodology in evaluating the supplier selection problems. Supplier selection
problems are complex problems, which have many qualitative and quantitative
concerns. In this study, an ANP model as a framework for evaluation of the
most important factor and selecting strategic supplier is proposed. ANP can be
used as a decision analysis tool to solve multi-criteria supplier selection
problems that contain interdependencies. ANP is a complex methodology and
requires more comparisons and efforts than the traditional AHP. To show the
application of the proposed mode, a case as an example is proposed.

Information systems decisions are of the main concerns of managers.
Existence of uncertainties and different objectives and attributes influence
the quality of decisions. Environmental uncertainties can challenge the
quality of IS investment decisions. Investment decisions, made without any
respect to environmental changes, will loose their effectiveness as time
passes. IS investment decisions require attention to different attributes such
as return on investment, strategic competitiveness and user satisfaction.
Multi-attribute decision making (MADM) approaches can play an important
role to make investment decisions. This study aims to integrate scenario
planning (as a tool to meet environmental uncertainties), Axiomatic Design
(MADM approach) and Fuzzy Delphi method (experts opinions acquiring
and consensus tool) as a Hybrid Model to propose a new methodology to
make IS investment decisions about the outsourcing or insourcing of the
development of the information systems. A case study in IS investment has
been done. The case is about the selection of an ERP system in Iranian
National Oil Company (NOC).

Governments, are not successful in implementation of many policies. Various
challenges, obstacles and constraints may occur and hamper the policy
implementation; but when a policy fails in implementation, only the
implementators are blamed; while policy-makers have a major role in the
(success and) failure of a policy, too. In fact, disrespect to rationality in policy
formulation can lead the policy process to failure in implementation. In this
study, according to Ignace Snallen (2002), the concepts of rationality consists of
legal, economical, political and professional dimensions. The hypothesis of this
research is that “rationality of the policies formulated in the 7th Islamic
Consultative Assembly of Iran” differs to “the optimum/ideal rationality that,
leads us to a successful implementation”. The necessary data were gathered
from the experts by questionnaire, and analyzed by statistics tests. Data analyses
confirmed the research hypothesis. It is concluded that disregard to the desirable
composition of rationalities has led the to unsuccessful implementations of
policies processes.

Risk management and improving the processes’ reliability are important in
operations and production management. Failure modes and effects analysis
(FMEA) is regarded as one of the most powerful methods in this area. High
applicability and proper analyzability have caused FMEA to be among the
most important techniques of systems’ risk analysis and safety improvement.
On the other hand, widespread application of this method in various
fields has revealed some weak points and constrains; subsequently many
researchers have offered revisions and modifications on it. In this article,
analytical network process (ANP), a modern and powerful method in
decision-making field, has been used in combination with FMEA (ANPFMEA)
for defeating the shortcomings.
ANP-FMEA considers mutual relationships of hazardous factors, and by
offering certain structure, develops a systematic and flexible view in risk
management scope. The suggested method deploys simple concept of risk
priority number and assigns different importance in the form of power for each
factor. The resulted RPN will cope better with the system, in which it is applied.
This method provides more accurate analysis of risk and, consequently, more
efficient and effective actions, causing attainment and maintenance of more
desirable reliability.

This research has been done with the aim of identification of the effective
factors that influence credit risk and designing a model for the credit rating
of the legal clients of Tejarat Bank in 2003-2004 by using Data Envelopment
Analysis. For this purpose, the necessary sample data on financial and nonfinancial
information of 146 companies (as random simple) was selected. In
this research, 27 explanatory variables (including financial and non-financial
variables) were identified and examined. Finally, with the application of
factor analysis and Delphi method, 8 variables, which had significant effect
on credit risk, were selected and entered into the DEA model. Efficiency of
the companies was calculated by using these variables. Then the model
validity was measured by regression analysis. The DEA credibility scores
represented the dependent variables while the 8 ratios used were considered
as independent variables. The findings of the research showed that 25
companies stand on the border of efficiency. Also with one exception
(owners equity/ total asset), ’all variables had the expected direction
α = %5 .
Research conclusions confirmed the hypothesis of DEA model’s
efficiency on credit rating of the companies who have taken credit facilities
from branches of Tejarat Bank in Tehran city.

One of the common problems in manufacturing firms is selecting the best
manufacturing system with regard to firm capabilities, market situation,
competitors and political and economical issues. Just-In-Time system is one of
the best manufacturing systems, which has many benefits. In contrast;
implementation of this system is very difficult because of various constraints.
Therefore, manufacturing managers encounter the problem of using or
not using this system in their firm. In this article, a decision making model
based on Analytic Network Process (ANP) is presented for analyzing this
problem in a printing factory for finding the appropriate manufacturing
strategy. To sum up, the decision making criteria were determined by
studying the literature, relevant articles and using Nominal Group Technique
among the experts. Then, the related decision making model was prepared
by expert interviews. Finally, the best strategy was selected by paircomparison
and solving the model.

Design and implementation of QMS will cause to the improvement of
organizational performance if it concerns on the especial characteristics of the
organization. In general, previous studies have obtained different results about
the effect of QMS (7 main practices) on organizational performance (4 main
practices). In this survey, the relationship between QMS and organizational
performance practices is analyzed using Structural Equation Modeling. The
results showed that QMS practices have a significant relationship with the
employee’s satisfaction, customer satisfaction and organization effectiveness,
but the relationship between financial practice and QMS is not significant.

In today’s markets, production systems must satisfy simultaneously
productivity, quality, and cost requirements. In these systems managers should
focus on managing the flow of production through all the steps that add value to
the final product. Lean production as an efficient approach has been presented in
the literature of production management for increasing the level of products'
quality and decreasing the cost of production. Although this approach is
introduced and studied in many of works, but there are still some challenges in
applying it. It means that there is not a comprehensive model for assessing and
analyzing the lean production in manufacturing firms. This paper tries to present
a model that is able to accurately analyze and measure the leanness degree of
firms.
At first step a hierarchical model for measuring the degree of leanness
has been designed. The proposed model applied at the Yazd Tile and
Ceramic Industries and the degree of leanness of these industries was
measured. Finally, some suggestions for improving the degree of leanness in
these industries have been presented.

Entrepreneurship is a general term that is used to both organizations and
individuals. Therefore, we cannot imagine an entrepreneur organization that its
people do not accurately understand about their ability and creativity.
Entrepreneurship acts as a driving force towards people and firms development.
We cannot expect an organization’s development without consideration of its
people. SMEs want that profitable companies should use all of their capacities
and it is easy with entrepreneurship. This paper focuses on the main factors as
management, organizational structure, strategic components, financial and
budgeting systems, evaluation of performance and cultural aspects in SMEs and
surveying of their roles on entrepreneurship filed in companies. The data
required were collected through questionnaires that offered to the employees and
managers of 25 companies in Kurdistan province. The research method was
casual comparative. Findings of the paper showed that entrepreneur firms
mangerial skills have a meaningful difference to those of non entrepreneur
mangers. This result is true for the financial and budgeting systems and
evaluation of performance and cultural characteristics in the studied groups.
There was no significant difference in the structural variables (concentration and
formality) and the strategic aspects (goal setting and policy making) in the two
firms. The results also showed that entrepreneur organizations are more complex
than others. Consequently, the innovators of small and medium enterprises have
a good mission statement in comparison to non entrepreneur firms.
