Taking the highly competitive markets into consideration, organizations need to be involved in activities that yield not only high performance, but also a competitive advantage. The present study was conducted to investigate the effect of collaborative structure and competitive intensity in the relationship between process management and organizational performance in Shiraz Municipality. The pr...

We introduce a new O(lg lgn)-competitive binary search tree data structure called poketree that has the advantage of attaining, under worst-case analysis, O(lg n) cost per operation, including updates. Previous O(lg lgn)-competitive binary search tree data structures have not achieved O(lg n) worst-case cost per operation. A standard data structure such as red-black tree or deterministic skip l...

The wavelet tree is a data structure to succinctly represent sequences of elements over a fixed but potentially large alphabet. It is is a very versatile data structure which exhibits interesting properties even when its compression capabilities are not considered, efficiently supporting several queries. Although the wavelet tree was proposed more that a decade ago, it has not yet been widely u...

abstract producing of flowers and ornamental plants in iran has some challenges and failure in the market structure and marketing of these products. in this study, we evaluated the different marketing channels of flowers and ornamental plants in the existing market structure according to economic criteria and the characteristics of market structure. cut-rose and esfahan province were selected a...

This paper proposes a general empirical framework to estimate the protection-for-sale model, where the protection regime shifts according to a sector’s market structure (perfectly or monopolistically competitive). We base the protection structure on Grossman and Helpman (1994) for the subset of perfectly competitive sectors and on Chang (2005) for the subset of monopolistically competitive sect...

A strategy S solving a navigation task T is called competitive with ratio r if the cost of solving any instance t of T does not exceed r times the cost of solving t optimally. The competitive complexity of task T is the smallest possible value r any strategy S can achieve. We discuss this notion, and survey some tasks whose competitive complexities are known. Then we report on new results and o...

Decisions in today's competitive and turbulent environments without access to information can confuse managers. The information system, which is planning, design and deployment as efficient and effective way, can help to improve the organization and create competitive advantage. One of the success factors and effectiveness of information systems in organizations is the organizational factors...

Remanufacturing is an industrial process that makes used products reusable. Remanufacturing is a way to establish a closed-loop supply chain. One of the important aspects in both reverse logistics and remanufacturing is pricing of returned and remanufactured products (called cores) that it has been noticed in this paper. In addition, in this paper the researchers have tried to present a mathema...
