Theoretical foundations of organizational problem solving methodologies in Operational Research
Paradigms are some principles and assumptions, which define frameworks and research priorities in each discipline. Many believe that operational research (OR) is not a science and like many other sciences does not have any paradigm. However, since OR is committed to scientific methods, therefore it contains a methodological paradigm. The purpose of this paper is to consider theoretical methodologies in the field of OR. This paper performs a review on the existing literature based on interpretive hermeneutic approach. Based on literature review, the study determines four principles and assumptions for each OR paradigms and a classification of the methods are presented. The results show that OR has four main paradigms and there are many methods in OR fields to tackle a particular problem where each problem belongs to a particular paradigm. In addition, instead of using a particular method in problem situations, we can implement a combination of methodologies

A Conceptual Framework for Knowledge Architecture in Large-Scale Organizations
The main concern for most organizations in this age, which has been called the age of knowledge-based economy, is their success and superiority in competitive markets. Reviewing the parameters that might have been effective on the success of operationalizing a knowledge management project leads us to a potential factor as knowledge architecture. With regard to the significant effect of knowledge management in the efficiency of organizations and the inclination of current organizations toward large-scale, we try to come up with a suitable architectural framework in such organizations. The initial structure of the framework was established based on the information architectural framework of Zachman. Then, we arrived at the ideal knowledge architecture framework by adding service abstraction and architecture level dimension besides changing the field of all the cells within Zachmanâs framework from information into knowledge. This research is descriptive in method and its validity is confirmed by executing a case study and soliciting the opinions of some knowledge architecture experts. The results indicate feasibility of applying framework to other knowledge-intensive large-scale firms and the findings of paper may be beneficial for architects in the knowledge area
Agility Evaluation by Using Verbal Variables in Fuzzy Logic and Ranking Fuzzy Numbers by Using Central Gravity Point Technique and Topsis (Case study: Yazd Alloy Steel Company)
In this article we try to collect all opinions of previous researchers in agility evaluation field and to provide a new method for evaluating agility by using Fuzzy logic. First, the structureâs agility level is evaluated by using FAI method. Due to the ranking Fuzzy numbersâ role and importance in making decisions, then the Fuzzy numbers are ranked by using central gravity point technique and Topsis. In fact, this leads to identifying those factors which caused the structure agility reduction. This method would help managers in making decisions
Identification and Ranking of Critical Success Factors of Knowledge Management Using Fuzzy Quality Function Deployment Approach: A Case Study
The main objective of this research is to rank the critical success factors of knowledge management using fuzzy quality function deployment (QFD) approach in MECO Company. The research has utilized a three-step qualitative-quantitative-qualitative strategy. At the first step (1st qualitative phase), the critical success factors of knowledge management and knowledge management outcomes were characterized in MECO. Then, the critical success factors of knowledge management which were identified by the first step were ranked using fuzzy quality function deployment in the second step (quantitative phase). Afterwards, some solutions were provided to realize and improve the critical success factors of knowledge management in the selected company within the third step of research (2nd qualitative phase).
11 critical success factors of knowledge management were introduced in addition to 4 knowledge management outcomes by the first qualitative phase. The result from the quantitative phase were indicative of the fact that âhuman resource managementâ, âsupport and leadership of managementâ, âorganizational infrastructureâ, âorganizational cultureâ and âactivities and processesâ are known as five critical success factors of knowledge management in the chosen company. Furthermore, 23 solutions provided by this research in order to realize and improve the critical success factors of knowledge management in this company are achieved as a result of implementing the second qualitative phase.
Based on the information accessible for the researchers, this is one of the first works which evaluates the key factors of successful knowledge management through fuzzy quality function deployment approach. It is expected that the proposed method would represent appropriate tools for enterprises which have decided to implement knowledge management because it prioritizes the critical success factors based on the knowledge management outcomes
Developing TOPSIS method using statistical normalization for selecting knowledge management strategies
Purpose: Numerous companies are expecting their knowledge management (KM) to be performed effectively in order to leverage and transform the knowledge into competitive advantages. However, here raises a critical issue of how companies can better evaluate and select a favorable KM strategy prior to a successful KM implementation.
Design/methodology/approach: An extension of TOPSIS, a multi-attribute decision making (MADM) technique, to a group decision environment is investigated. TOPSIS is a practical and useful technique for ranking and selection of a number of externally determined alternatives through distance measures. The entropy method is often used for assessing weights in the TOPSIS method. Entropy in information theory is a criterion uses for measuring the amount of disorder represented by a discrete probability distribution. According to decrease resistance degree of employees opposite of implementing a new strategy, it seems necessary to spot all managersâ opinion. The normal distribution considered the most prominent probability distribution in statistics is used to normalize gathered data.
Findings: The results of this study show that by considering 6 criteria for alternatives Evaluation, the most appropriate KM strategy to implement in our company was ââPersonalizationââ.
Research limitations/implications: In this research, there are some assumptions that might affect the accuracy of the approach such as normal distribution of sample and community. These assumptions can be changed in future work.
Originality/value: This paper proposes an effective solution based on combined entropy and TOPSIS approach to help companies that need to evaluate and select KM strategies. In represented solution, opinions of all managers is gathered and normalized by using standard normal distribution and central limit theorem.Peer Reviewe
Simulating the effects of Knowledge co-creation policies in supply chain on NPD performance using system dynamics
Partnerâs decision and policy making about allocating resource to innovation activities in a supply chain is not a static situation and to achieve a sustainable competitive advantage, the previous decisions must be reviewed continuously. However, this dynamic decision making process cannot be provided by the current static view. So, the current study presents a dynamic model to investigate endogenous and exogenous changes through designing feedback mechanisms and using system dynamics approach. Also, it provides a tool to analyze the behavior of system using different scenarios and policies. In addition to presenting the Cause and Effect diagram and Flow diagram, the study findings show that the most appropriate investment policy on innovation activities is the policy that allocates the resources based on the gap performance
