毫微微小区中一种基于分组的资源分配方法

为有效解决毫微微小区间（Femtocell）干扰,采用分布式方式对毫微微小区进行资源管理。首先,对毫微微接入点（FAPs）进行分组。基于Lingo数学建模的思想,提出了一种解决分组优化问题的算法。该算法在使用分支定界算法寻找最优解的同时,通过建立单纯形表剪去偏离最优解方向的分支;其次,每组选择一个簇头为本组内FAPs分配资源,为此,提出了新的子信道分配方法,该方法根据干扰指示矩阵修正子信道分配的情况。仿真结果表明：和其他算法相比,提出的算法不仅能找到分组优化问题的最优解,并且效率更高;另外,提出的资源分配算法不仅减小了用户间干扰,而且提高了户间速率公平。     

超密集小区中基于二分图优先级的资源分配算法

由于在超密集网络中小基站密集的部署,用户数据量空前增加,对数据速率的要求不断提高,所以在有限的资源下如何高效地将资源分配给用户尤为重要。提出了一种小区分簇算法,根据小区簇的通信业务、通信负载量等条件将各个小区分为不同的优先级,引入二分图,以小区簇的优先级为依据建立频谱资源与小区簇之间的匹配关系,并提出一种低复杂度的贪婪算法。仿真结果表明所提算法能够有效提高系统性能,并且有效完成频谱资源的分配。     

C-RAN架构中适用于干扰消除的资源分配机制

针对在C-RAN（Clean-Radio Access Network）架构无线网络中的干扰消除机制会带来背景噪声放大的问题,利用C-RAN架构网络的集中式处理,从而可以对全网络系统求解干扰。在定义网络背景噪声放大因子的基础上,将网络中背景噪声放大的最小化问题建立为以资源分配集合为可行空间、以最小化背景噪声放大因子为目标函数的最优化数学模型,并给出了利用遗传算法进行求解的方法,在此基础上设计了资源分配的机制。对该机制的仿真结果表明：将此机制应用到C-RAN构架网络中,能有效降低误码率,提升网络中用户公平性和吞吐量。     

A resource dependence perspective of EMNE FDI strategy

Using Resource Dependence Theory as a lens, we explore current explanations of how and why Emerging Market Multinationals (EMNEs) seek to compete internationally through Foreign Direct Investment. We find that all three dominant explanations and much of the ongoing literature either explicitly or implicitly highlight the importance of a firm's ability to acquire and maintain resources to its own survival and ability to compete as latecomers on a global stage. Through our conceptual model we show that whether EMNEs seek to exploit existing resources, seek to augment their resource base, or pursue a combination of both it is reflected by their generic internationalization strategy. This generic strategy is also reflective of the firm's strategic focus, as well as predictive of its entry mode and resulting resource dependence. Taking this perspective informs the current literature by clarifying how an internationalization strategy alters EMNE dependence on the external environment for critical resources.     

Strategic intent and performance: The role of resource allocation decisions

The notion that a firm's strategic intent can affect its performance through managerial actions has become prominent in the organization literature. In this research, we propose that strategic aggressive firms will foster decisions that favor holding low levels of slack and low levels of R&D investments, resulting in increased firm ROI, and that a firm's risk preference will moderate the indirect effect of strategic intent on performance. Findings from moderated mediation analyses on data from 130 firms in manufacturing industries support our hypotheses. Specifically, the indirect effect of a firm's strategic intent on a firm's performance is moderated by its risk aversion, such that when risk aversion is high, the indirect effect of strategic intent on performance through slack is strengthened. Similarly, the indirect effect of strategic intent on firm performance through R&D investments is strengthened, when risk aversion is high.     

Negotiation and design: Supporting resource allocation decisions through analytical mediation

The common element of all negotiations is change. Design is the key to directing and managing change, and resource allocation is the most critical component of design. Negotiations about change are, therefore, fundamentally, negotiations about design and resource allocation. Negotiations vary along a continuum, from those in which negotiators have consonant interests (share objectives) to discordant ones (disagree about appropriate objectives). The joint distribution of all possible payoffs defines thestructure of the negotiation problem—the opportunities the problem affords and constraints it imposes on negotiators. The analytical mediation approach supports the activities of an impartial, neutral third party who attempts to assist the disputants to reach a mutually satisfactory agreement. It makes use of different types of techniques to support negotiations, depending on their location along the negotiation continuum. Two case studies involving analytical mediation are reported. One case study involves a budgeting exercise, in which the negotiators' interests were essentially consonant. The second case study involves a labor-management contract problem, in which the negotiators' interests were highly discordant.     

Ethics and politics of resource allocation: The role of nursing

The use of ethics in everyday nursing practice will become increasingly important to the individual nurse, and nursing as a profession, as technology has a greater impact on health status and the provision of health care. Resource allocation is only one example of an ethical issue in which nursing must have input. Nursing can expand its contribution to society by ensuring that it plays a major role in shaping public policy and legislation. If nursing is to continue to serve the public, the involvement of nurses within the political process must be accepted as an ethical necessity.Margaret Keatings, RN, MHSc, is the Director, Nursing Practice in the Department of Medicine at Toronto General Hospital. She combines this role with a strong interest in biomedical ethics to serve as co-chair of the hospital's clinical ethics committee. Keatings is also an assistant professor in the University of Toronto Faculty of Nursing. In spring 1988, she participated in an exchange program between Toronto General Hospital and a teaching hospital in Cambridge, England.Diana Dick, RN, BScN, MEd, co-ordinated a national campaign of the Canadian Nurses Association resulting in two significant amendments to the Canada Health Act (1984). As Project Manager with the Registered Nurses' Association of Ontario, she initiated the Association's involvement in the Grange Inquiry. She has taught at Seneca College, practised nursing in special care units, and written and spoken both nationally and internationally on resource allocation. Currently she works in a branch of Ontario's Pay Equity Commission.     

使用对偶分解的MU-CoMP-JT联合资源分配

在MU-CoMP-JT（Multi-User Coordinated Multiple-Points Joint Transmission）联合资源分配问题中,传统的迫零预编码矩阵会使得每根天线发送功率互不相同,当CoMP节点发射功率仅满足总功率约束时性能损失不明显,而当CoMP节点分布在不同的地理位置时将受到单节点功率约束,这势必会降低系统功率利用率。为了进一步提升系统吞吐量,基于对偶分解理论提出了一种联合预编码优化的资源分配算法。该算法以最大化用户权重速率为目标,将原优化问题分解成若干个优化的子问题,不同子问题对应不同接收天线数的联合优化问题。当子信道的发送天线数大于接收天线数时,通过多次迭代计算得到预编码矩阵,并且预编码矩阵会随着拉格朗日因子的变化而变化。仿真结果表明所提联合预编码优化的联合资源分配算法能够明显提升系统吞吐量,且提高天线功率利用效率。     

Co-alignment in the resource–performance relationship: strategy as mediator

Small firms face unique challenges in crafting strategies that best utilize their resource bases. Research shows strategies that combine with resources lead to performance. The entrepreneurship literature finds the contingent effects, or moderating roles, of strategy and external factors, but the relationship between firm strategy and internal factors, such as resources, is less well studied. Based on the contention that the quality of a firm's strategy cannot be judged independently of the resources upon which it is based, we examine the relationship between firm resources, strategies, and performance in a cross-section of 192 small firms. Using a structural equation analysis, we examine the mediating role of firm strategies as they lead to firm performance in small firms operating in traditional industries. Our findings demonstrate that neither resources nor strategies alone explain firm performance, but instead, small firms fit their strategies to their resource profiles. Human and organizational resources in combination with a strategy of quality/customer service enhance firm performance.     

Organizational goals and resource allocation to overseas foreign direct investment

We investigate how organizational goal setting impacts slack resource allocation between markets at home and overseas, and argue that organizational goals, publicly announced, impact managers’ evaluations of resource allocation opportunities. Based on a sample of Chinese publicly listed manufacturing firms for the period 2010 to 2016, we find that when firms announce publicly a sales increasing goal as their priority, their attention will be focused on this goal with a tendency to invest the firm's slack resources locally. This tendency to invest slack resources locally is enhanced if the announced goal is not achieved, but is not achieved with a minor discrepancy. However, if the goal is not achieved, and with a major discrepancy, managers will likely conduct problemistic search and look to foreign locations to invest the firm's slack resources to achieve this goal. We also find the impact of organizational goal setting is more salient for SOEs and is dependent on levels of remuneration in the firm. As such, we revisit the importance of organization goals and the resource allocation decision in the firm which has not received the research attention one may have expected.

Collaborative production and resource allocation: the consequences of prospective payment for hospital care

This article presents a model of the intensity of care provided by hospitals and physicians and how such intensity was affected by the change to prospective payment by Medicare. Prospective payment introduced an incentive for hospitals to shorten average length of stay, but in order to keep the patient recovery level constant, intensity of inpatient care was forced to increase. Physicians reacted to hospital changes by increasing their own intensity of care provided to inpatients. Implications of the model for admissions and physician office time are also explored. Empirical results indicate that for the period 1983-1987, spanning the introduction of PPS, both hospital and physician intensity of care per inpatient rose significantly.

Franchisor strategy and firm performance: Making the most of strategic resource investments

A key decision for entrepreneurs in many retail and service firms is whether, and how much, to use franchising. If the decision is made to franchise, the actor may assume one of two “identities” or tactics: (1) the “chain builder,” who uses a blend of company and franchised outlets, and (2) the “turnkey,” who sells business opportunities but does not own any outlets. To benefit from their chosen strategy, franchisors must put resources in place to support it. We argue that franchisors use the chain building strategy to strike a balance between standardization and innovation by building resources that foster trust and encourage knowledge sharing with franchisees. In contrast, for turnkeys, a valuable set of operational routines is the critical strategic resource. To better appreciate how franchisors choose between the chain builder and turnkey strategies, we gathered survey information from 263 franchisors. Via this data, and as described herein, we learned that franchisors perform better when they invest in resources that best support their selected strategy.     

主用户活跃性下的多功率分配策略

考虑到认知用户在信息传输过程中主用户的状态可能随时变化,提出了一种新的功率分配模式——多功率分配策略。在基于频谱感知的系统模型中,以认知系统的吞吐量为目标函数,得出了主用户感知过程的多种状态,并分配三种不同的功率,最大化认知系统的容量。仿真结果表明,随着主用户活跃指数的逐渐提高,所提新模型的功率分配策略要优于传统方法。同时分析了新的功率分配下平均干扰功率与主用户接收端的信噪比对系统吞吐量和最优感知时间的影响,进一步验证了所提出新策略的有效性。 〖HT5H〗关键词：〖HT5K〗认知无线电;主用户活跃;频谱感知分配;多功率分配;吞吐量最大化     

D2D通信中一种资源分配与功率控制结合的方案

以underlay方式工作的D2D(Device-to-Device)通信通过资源共享复用蜂窝网络中的资源,在提高系统资源利用率的同时,对已有蜂窝链路带来了同频干扰。为了减小因无线资源复用带来的干扰,提出了一种资源分配与功率控制相结合的方法。以最小化系统干扰为目的,通过在D2D链路之间合理地分配资源,保证了蜂窝链路的通信质量;同时动态地调整D2D链路的发射功率,在保证相应蜂窝链路干扰可控的情况下,合理提高了D2D链路的通信质量。仿真结果表明,与现有方案相比,所提出的算法能够有效地提高D2D通信与蜂窝用户共存场景下的系统性能。     

基于资源分配和功率控制的D2D中继选择

为优化蜂窝用户通信与设备直传（D2D）中继通信共存下的同频干扰问题,满足蜂窝用户容量要求,提出了一种基于能效的联合资源分配和功率控制的D2D中继选择算法。该算法首先对等效D2D中继链路进行资源分配,减小算法复杂度的同时使得D2D链路对蜂窝链路产生的干扰最小;然后以资源分配结果和功率控制算法为依据进行中继选择。该方案不仅考虑了D2D中继链路的能效问题,而且还同时考虑到了对蜂窝链路的干扰问题。通过仿真验证,所提算法不仅能有效提升D2D中继链路的能效值,同时降低了对蜂窝用户的干扰。
