There is a large number of literatures about routing and dispatching plans for automated guided vehicle system (AGVS), however a small fraction of these works dealt with dynamic characteristic of this kind of scheduling problems. Current paper surveys a real time strategy to responding requests for supposed material handling system in the plant. We arranged this designing on a preplanned system where all data are known before the constructing routes. An improved ant colony optimization (ACO) is applied in order to find the shortest route path as new solicitations happened. We explore ACO initially for static version of the problem, …

Nothing is permanent except change. Many authors stress that the reason for the failure of many change initiatives can be found in resistance to change. Resistance to change introduces costs and delays into the change process that are difficult to anticipate but must be taken into consideration. Undoubtedly the resistance to change is key topic in change management and should be seriously considered to help the organization achieve advantages of the transformation. Considering the importance of resistance to change, this paper aims to delve deeper in this field through theoretical exposition of the concept, elaborating more on the literature involving …

Research and Development (R&D) management in Iran has faced many barriers and obstacles, in which R&D units are considered as the basic core of the product development and innovation. Due to structural shortcomings, a great number of organizations and industries have not yet been able to position themselves in the market. There are about 1141 R&D units throughout Iran, due to the geographical decentralization of these units this paper considers and analyzes the R&D case study in one of the provinces located in the north part of Iran, and the findings can be generalized to the other industrialized areas and …

Research and development has always played a strategically important role in the survival and the growth of technology-based firms. R&D is positively linked to company performance measures such as sales, productivity and shareholder returns and in addition to this, facing increased competition, as a result of globalization the viability of many established firms is based on the efficiency of their R&D activities. Similar to other business models, R&D systems are characterized by complex structure and dynamic behavior. It's often difficult to predict or trace the consequences of certain decisions due to the existence of delays, non-linearities and causal feedback inherent …
