The Physical Internet (PI) concept presents a radical change with the aim to revert the unsustainable practices that are used for transporting goods. It identifies dedicated freight flows and transforms them into transparent open logistics networks which can be accessed by other users, such as shippers and carriers. In this paper, we test the universal network openness in which the users can tap into the PI network and place orders that will be assigned to the nearest available transport service and consequently delivered to the order sender. The objective of our paper is to investigate the impact of inserting extra service points into existing dedicated freight flows of a service‐driven company. We simulate different transparency levels and routings to new pickup locations and evaluate the impact in terms of altered lead times, covered distances, and fill rates. The novel aspects presented herein are (1) deliveries based on decentralized location detection of the nearest order sender, (2) dynamically changing speed parameters of agents within specific geographic clusters based on their geo‐locations in order to account for congestion levels, (3) more realistic routing strategies that consider the urban layout, and (4) transparent querying of nearest agents in space and time that meet specific conditions such as current ongoing processes, available capacity, and position. Finally, we identify the impact from a general/holistic perspective that emerges once extra orders are assigned to the service‐driven company's fleet.  相似文献

Significant increases in the level of target leverage have been previously documented following unsuccessful takeover attempts. This increased leverage may signal managerial commitment to improved performance, suggesting that corporate performance and leverage should be positively related. If, however, the increased leverage leads to further managerial entrenchment, then corporate performance and leverage should be negatively related. In this paper, we reexamine both motivations for the observed increase in leverage. Furthermore, we argue that changes in the composition of debt are also important, besides changes in the level of leverage. In particular, bank debt has frequently been assigned a proactive, beneficial monitoring role in the literature. Besides confirming the increase in the level of leverage, we also document increases in bank debt surrounding cancelled takeovers. As a result, we find a more complex relation between corporate performance and debt use: Overall, the relation between corporate performance and leverage is negative, as predicted by a dominant entrenchment effect. However, increases in bank debt reduce the adverse effect of the increase in the level of leverage.  相似文献

This paper revisits the literature on farm restructuring in the CEECs by analysing the variations in farm performance in the Czech Republic a decade after the start of the transition process. It identifies seven clusters of farms that differ in their productivity and profitability usng data from 1998 and 1999. The analysis reveals that the vast majority of farms are unprofitable, and there is no strong evidence that individual farms perform better than corporate farms. In fact, there are large numbers of individual farms that are loss‐making on their agricultural activity with low factor productivity. Producer co‐operatives and limited liability companies suffer from debts inherited from the reform process. Future restructuring is likely to occur in all clusters rather than affecting just corporate farms.  相似文献

This paper investigates the evolution of corporate governance and firm performance in transition economies. It focuses on barriers that impeded adoption of optimal corporate governance at Czech ammunition manufacturer Sellier and Bellot (S&B) following voucher privatisation in 1993. Exogenously imposed diffuse ownership, combined with legal, capital market, and accounting deficiencies, contributed to poor corporate governance and weak firm performance. This study shows how legal, capital market, and accounting deficiencies hinder corporate governance evolution; it demonstrates monitoring and incentive mechanisms can create value in transition economies; it suggests effective privatisation not only involves rapid ownership transfer but careful accounting and securities regulation and legal protection.  相似文献

The present paper analyses both managerial and program efficiencies of Lithuanian family farms, in the tradition of Charnes et al. (Manag Sci 27(6):668–697, 1981) but with the important difference that multi-directional efficiency analysis rather than the traditional data envelopment analysis approach is used to estimate efficiency. This enables a consideration of input-specific efficiencies. The study shows clear differences between the efficiency scores on the different inputs as well as between the farm types of crop, livestock and mixed farms respectively. We furthermore find that crop farms have the highest program efficiency, but the lowest managerial efficiency and that the mixed farms have the lowest program efficiency (yet not the highest managerial efficiency).  相似文献

This article discusses entrepreneurship in a depleted community in transition. The purpose is to develop knowledge about how discourses are used in the positioning of identity in regional development. The concept positioning illustrates how identities are provoked, challenged, negotiated and moved into identity positions that break away from the idea of imitating successful and wealthy regions; instead, locality, place and history emerge as important resources from where local actors obtain agency and recognize new opportunities. Ethnographic data of a single case were collected over a six-year period between 2005 and 2010. The longitudinal nature of the study made it possible to incorporate how local stakeholders took on new identity positions, while handling their inspiration as well as their frustration. Results show how rural change was conditioned by discourses and how entrepreneurship challenged and reframed dominating structures through interaction between entrepreneurship and community. Four discourses, expressed as dichotomies available to people in this depleted community, illustrate the interactive process of positioning: change vs. traditions, rational vs. irrational, spectacular vs. mundane and individual vs. collective. The results support research emphasizing perspectives that acknowledge interaction between entrepreneurship and context as well as discursive aspects of regional development.  相似文献

Self‐organizing maps (SOMs) have commonly been used in temporal applications. This paper enhances the SOM paradigm for temporal data by presenting a framework for computing, summarizing and visualizing transition probabilities on the SOM. The framework includes computing matrices of node‐to‐node and node‐to‐cluster transitions and summarizing maximum state transitions. The computations are linked to the SOM grid using transition‐plane visualizations. We demonstrate the usefulness of the framework on two SOM models for temporal financial analysis: financial performance comparison of banks and monitoring indicators of currency crises.

The early 20th century was a period of rising marriage rate and falling age at marriage. This was due to two factors affecting men. First, men's improving labor market prospects made them more attractive as marriage partners. Second, immigration had a dynamic effect on search costs. In the short-run, it fragmented the marriage market, making it harder to find a partner of one's preferred background. The high search costs led to less marriage and later marriage in the 1890s. In the long-run, as immigration declined, immigrants' descendants integrated with American society. This reduced search costs and increased the marriage rate.  相似文献
