        The design and development of system software is extremely costly and time-consuming. On the other hand, system softwares have own customers. In Iran, the time between product presentation to a customer and requesting and accepting a customer to buy system software is very long. This has led to an enormous increase in sales and marketing costs of Iranian knowledge-based companies. Accordingly, The Iranian System Software Developer knowledge- base Companies need to be able to increase their sales success rate by determining the correct product target market. The present paper, using the Multi-Criteria Decision Making Method (MCDM), attempts to provide guidance on the precise determination of the system software's target market for Iranian knowledge- base companies. The proposed method has been implemented in the PDNSoft Co. as a knowledge- base company and as a case study and one of the Iranian developers of system software product. The implementation of this method showed that the target market in Iran should consist of some groups of government customers. This method has improved the customer attraction rate from 0.06 to 0.13 per month. Manuscript Document

        Supply chain network design includes key decisions that have a major impact on the supply chain operational structure. Efficient supply chain design improves performance in organizations. This has led to the emergence of new concepts in the supply chain issue in the past decade. In this study, the supply chain network design problem in agile organizations has been taken into account with multi-level and multi-period. This problem is considered under conditions of having multiple customers with a high demand volume. The decisions include the selection of companies at each level, the amount of production, storage and transportation of each company. The problem has been modeled to integrate all decision variables with the goal of minimizing overall operating costs across the entire supply chain and Satisfaction of customers' complete demand and Satisfaction with them. Since multi-period multi-level supply chain design problem solving is one of the NP-Hard issues in uncertainty conditions, it is better to use innovative and meta-algorithms to reduce problem solving time. For this reason, the algorithm for banning search algorithms, which is one of the meta-algorithms, has been used to solve the model. The results of this research show that as the number of problem-solving repetitions increases, answers with less than 3% of the difference between the optimal answer are achieved. The search algorithm is forbidden to get the optimal response compared to the Lagrange algorithm. Manuscript Document

        Todays, product development has faced the dramatically growth, due to the rapid changes in customers’ demands, needs and the competitiveness of the market. Success in new product development requires a deep understanding of our customers. And this necessitates an interactive and active interaction with them. New product development is a way to listen to what customers want and also, to response their needs. Creating customer participation capability causes innovative and practical ideas and enhances firms’ competitive environment. Therefore, the purpose of this paper is investigating the effect of customer involvement capability on the success of the new product development. Also, this research attempts to develop previous researches by considering the effect of customer knowledge assimilation as a mediating variable and the moderating role of resources slack of company. This article is practical in term of purpose and descriptive in term of method. Questionnaire is used to collect the data. And 30 knowledge-based companies in Rasht city participated in this research. In order to test the hypotheses, the Structural Equation Modeling approach has been used. The research findings show that the customer participation capability directly and indirectly through the absorption of customer knowledge affects the success of the new product development; however, the role of resources slack as a moderated variable is not confirmed by the relation between customer knowledge assimilation and the success of new product development. Hence, knowledge-based companies need to pay particular attention to knowledge assimilation and customer involvement capability in order to succeed in new product development. As a result, they can possess an appropriate competitive position in the marketplace. Manuscript Document

        The main aim of this paper is to identify the knowledge elements that play a crucial role in the internationalization process of companies. Reviewing research literature shows, Companies that use the two-dimensional model for business knowledge divide knowledge into two dimensions: explicit or tacit nature, and the nature of the codified or uncodified. This model states that the tacit knowledge is difficult to transfer to others, while the explicit and uncodified knowledge component is the simplest form of knowledge for transferring to others. The statistical population of the study consist of managers and experts of the foreign trade sector (export and import) of companies that were present in international markets. For this purpose, 104 companies were selected from among five different types of business in East Azerbaijan province, and for data gathering, questionnaire was applied. Findings show that all variables of individual competency of employees, organizational beliefs and habits, and corporate procedures are related to the degree of internationalization. However, the strongest link between internationalization and various elements of business knowledge was identified in the field of organizational beliefs and habits, and individual competence of employees.

        With the advent of growing knowledge of the economy and the rapid growth of technology, intellectual property has become the focus of attention of corporate investment managers and researchers. Patent are considered to be the most important intellectual asset, and one of the reasons for this is the extensive research that has been done on the various dimensions of these rights. The patent provides the possessor with the possibility to use the technology exclusively for a limited period (often twenty years). Since many industrial and service companies need to acquire new technologies by the purchase of patent rights to maintain their competitive advantage and sustained business growth, the issue of patent assessment has become a serious challenge in the field of technology. In this research, a model for evaluating and ranking patents based on multi-criteria programming methods is presented and then the resulting model is implemented in a cell phone company. The company is required to choose a technology from four technologies: (1) a dual display, (2) missing phone tracking, (3) wireless communications security, and (4) remote banking to develop its products. The implementation of the model is based on four main criteria: (1) the essence of technology, (2) the cost of technology, (3) the product market, and (4) the technology market in the company led to the choice of wireless security technology. Also the accuracy of the result obtained from the implementation of the research model has been confirmed by the method of ELECTRE. Manuscript Document
