Achieving the full worth of IT investments is an important task of top management but questions remain as to what factors lead to improved returns and how do such investments impact organizational performance. Using a postal survey of 273 CIO respondents, this study analyzed the relationship of knowledge sharing and rational planning to IT-based organizational performance. Knowledge sharing was...

In this paper, a new object tracking system is proposed to improve the object manipulation capabilities of service robots. The goal is to continuously track the state of the visualized environment in order to send visual information in real time to the path planning and decision modules of the robot; that is, to adapt the movement of the robotic system according to the st...

Management of mobility especially balancing the load of handoff for wireless networks is an essential parameter for wireless network design and traffic study. In this paper, we present analytical mobility management in high speed wireless mobile networks focusing on factors such as the number of channel slots and offered load. We demonstrate the performance of handoffs with mobility considerati...

In this paper we bridge the gap between performance evaluation and the modelling of business processes. On the basis of a case study from the field of operational planning processes we investigate the performance evaluation of human resource management processes. In particular we consider the affect of timing in operational planning processes. We use TimeNET for modelling. It provides methods n...

In this paper, we present a geometric method for motion planning for a fleet of differentially driven mobile robots moving in formation, that explicitly takes in to account their nonholonomic constraints. The relative position of each mobile robot within the formation induces different motion plans for the individual mobile robots. By using a suitable metric, defined on the motions of each mobi...

Based on single dimension of economics, IT Performance evaluation model can no longer perfectly explain IT productivity paradox. This paper proposes a multidimensional evaluation framework including social, psychological, cognitive, economic, managerial dimensions. Drawing on symbolic informatics theory, this paper analyzes several questions. What is the ERPII performance? What is personalized ...

This paper provides means for performance evaluation of a queue with Poisson Pareto Burst Process (PPBP) input. Because of the long range dependent nature of the PPBP, straightforward simulations are unreliable. New analytical and simulation techniques are described in this paper. Numerical comparison between the results shows consistency. Conservative dimensioning rules using zero buffer appro...

Robotic manipulation and grasping in cluttered and unstructured environments is a current challenge for robotics. Enabling robots to operate in these challenging environments have direct applications from automating warehouses to harvesting fruit in agriculture. One of the main challenges associated with these difficult robotic manipulation tasks is the motion planning and control problem for m...
