基于和谐度的虚拟企业利益分配策略研究

为了满足成员企业参与虚拟企业获取利益目标的同时有效提高联盟各方的和谐程度,避免合作中的冲突和利益损失,确保虚拟企业的稳定性.在对虚拟企业利益分配策略的制定中,借鉴和谐管理理论中系统和谐度的概念,提出了虚拟企业利益分配和谐度的定义,并据此在考虑和谐度的基础上提出虚拟企业的利益分配方案.最后,通过算例,将基于和谐度的虚拟企业利益分配解与传统的利益分配方法Shapley值法的解进行了比较与分析.结果表明:该方法充分考虑了不同参与方的不同利益分配要求,有效地弥补了Shapley值下参与人无差异的不足,使整个联盟的利益分配趋于高度和谐,保证了虚拟企业持续稳定的发展.     

基于梯形模糊数的加权Shapley港口物流服务供应链收益共享分配

港口物流服务供应链纵向整合已经进行的如火如荼,但随之也出现了各主体之间收益共享分配不均匀、联盟结构不稳定等问题。为此本文应用Shapley值法对运输企业之间的共享收益进行初始分配,分配结果满足了个体和集体理性,但尚未考虑资源投入、风险承担、市场与品牌效应等实际因素对收益分配的影响。考虑到以上问题本文建立了基于梯形模糊数的加权Shapley值法,对初始分配方案进行了修正;对比两个分配方案结果显示小型运输企业为了维持联盟稳定性会让出部分利益;另外各个运输企业为了更高等级的优惠政策均会积极寻找货源,从而形成港口物流服务供应链上收益增加的良性循环。

联盟下班轮箱位租用与配置决策分析

航运联盟之间通过箱位资源的合作，发挥规模经济的优势，提供优质服务，提高竞争能力，使联盟方获得比原来更大的利益。以班轮航线配船方法为基础，建立联盟下集装箱班轮箱位租用与配置决策模型，用于分析和研究联盟情况下集装箱班轮公司箱位租用与配置方面的航线运力合作的实施与决策问题。通过实例分析表明，航运公司通过航运联盟箱位租用，在降低其系统成本、弥补航线运力、保证完成货运任务等方面有较好的优点。     

基于Raiffa解法与最大熵值法的供应链联盟利益分配对比分析

为了选择一种使供应链联盟企业间更易于接受的利益分配方案,本文借助Raiffa解法和最大熵值法模型,通过采用正交投影法求解出成员企业各自所承担的综合风险因子,并将其作为风险补偿进行模型修正。分析表明,考虑综合风险因子进行利益分配的修正后,raiffa解法求得的成员企业利益分配额存在较大偏差,最大熵值法更易于被供应链联盟企业所接受。     

现代港航物流的发展趋势——港航企业合作联盟化

在阐述班轮运输企业横向合作联盟——航运联盟的演变及发展的基础上，从联盟力度、运力情况、货主的选择等3个方面分析P3网络联盟对航运市场造成的影响。班轮运输企业与港口之间纵向合作联盟的发展趋势表现为：班轮运输企业具有港航合作联盟的主动权；拥有深水良港的码头运营商具有竞争优势；未掌握运力的国际港口经营商处境艰难。在竞争与合作的时代，港航企业应集成一体化共建全球物流服务网络，提高港航企业整体竞争力。     

联盟——向航运边界延伸

近年来,国际航运市场竞争日趋激烈,班轮运输业首当其冲。各大公司为削减成本,保持市场份额,纷纷重组联盟。与此同时,在班轮联盟的带动和影响下,港口、代理以及制箱业联盟也正在悄然兴起。 一、班轮联盟持续发展 班轮市场运价波动下滑及激烈的竞争,促使国际班轮运输业不断调整经营策略,其中最突出的是纷纷重组新的联盟。由于新联盟的合作范围比班轮公会和共享舱位协议都要广泛、且联系更为紧密,通常能够参与多条航线的运输经营,因

宁波港:软硬件齐发力

一、对航运业的影响 1.联盟合作成为集装箱班轮市场发展趋势 面对日益激烈的市场竞争,班轮公司争相建造大型集装箱船舶,以期获得规模效益。但是,大船是否能够实现规模经济效应,取决于是否能够以较高的装载率营运。船舶大型化带来的货源压力,以及信息技术发展提供的保障,使得寻求联盟合作已成为集装箱班轮市场的发展趋势。     

一类供应链下游企业合作利润分配机制研究

仅以合作关系作为供应链利润分配机制是与共享原则相悖的,且也无法实现。基于合作利润分配机制应包括的结构要素和运行要素之间的辩证关系,建立了一厂一商的供应链合作利润分配机制的数学模型。通过对该模型的求解,确定了厂商和渠道利润的数学表达式,定量描述了机制结构要素与运行要素之间的“硬件”与“软件”关系,并对它们的变化区域与对各决策变量及利润的影响程度进行了深入的分析,对现行返利系数的应用进行了讨论;构造出了一种较为有效的供应链合作利润分配机制。     

Cooperation among freight forwarders: Mode choice and intermodal freight transport

The objective of this paper is to compare vertical and horizontal cooperation among freight forwarders. The paper analyses three freight forwarders (‘players’) with two different means of transportation. The first two players are truck-operating freight forwarders. The third player is a freight forwarder with its own ship. For the purposes of analysis, the paper applied a two-stage game. The results revealed that the best form of cooperation is the one in which the large truck-operating company would establish a coalition with the ship-operating company; that is, vertical cooperation. This cooperation would generate better payoffs in the form of profit, not only to the members of this coalition, but also to the player that has not joined the coalition. However, user surplus is negative in all coalitions, which shows that the establishment of these kinds of cooperation is not beneficial (in terms of prices) for the users of these service providers.     

港口码头重复建设的博弈分析

通过建立两个码头之间的完全信息静态博弈模型和完全信息动态博弈模型分析了港口码头的重复建设现象。认为重复建设的根本原因在于各个港口对经济腹地的预测值偏高,港口之间缺乏协调合作,以致于在竞争中产生一种类似“囚徒困境”的心理。本文给出了解决港口码头重复建设问题的若干政策建议。     

S~2 BHCA-Multiple AUVs cooperation oriented control architecture

Oceanographic survey, or other similar applications should be the applications of multiple AUVs. In this paper, the skill & simulation based hybrid control architecture (S2BHCA) as the controller's design reference was proposed. It is a multi-robot cooperation oriented intelligent control architecture based on hybrid ideas. The S BHCA attempts to incorporate the virtues of the reactive controller and of the deliberative controller by introducing the concept of the "skill". The additional online task simulation ability for cooperation is supported, too. As an application, a multiple AUV control system was developed with three "skills" for the MCM mission including two different cooperative tasks. The simulation and the sea trials show that simple task expression, fast reaction and better cooperation support can be achieved by realizing the AUV controller based on the S2BHCA.     

Disaster prevention and strategic investment for multiple ports in a region: cooperation or not

With the growth of maritime transportation, seaports have become critical to the world economy as linking nodes between shipping and inland transport. However, the port system is fragile under certain unconventional emergency events. This study addresses the issue of investment on disaster prevention within the port competition context. The present model discusses and compares four situations of different relationships and strategies of pre-disaster prevention between two adjacent ports. Results indicate that both ports increase the disaster prevention investment under the cooperation scenario compared with that in the case of non-cooperation wherein they are complementary ports. Meanwhile, a numerical simulation is conducted to examine the collective and individual rationality of both ports. Although cooperation strategy decreases the total risk cost of two ports, one of the two ports may profit, whereas the other may suffer losses.

Fleet deployment in liner shipping: a case study

The fleet deployment problem is an important planning problem in liner shipping. It deals with optimally assigning voyages to available vessels in the fleet and determining vessel routes and schedules in a way that minimizes costs or maximizes profit. This paper presents a new model for a fleet deployment problem in liner shipping, and we also propose a multi-start local search heuristic to solve the problem. The heuristic has been embedded in a prototype decision support system (DSS) that has been implemented and tested at Höegh Autoliners, a major global provider of ro-ro (roll-on roll-off) vehicle transportation services. The heuristic was able to produce high-quality solutions within a few minutes to a real planning problem with more than 55 vessels and 150 voyages over a planning horizon of 4–6 months. Tests indicated that the solutions suggested by the DSS gave between 2 and 10% improvements compared with solutions from manual planning. What is almost equally important is that using the DSS can ease the planning process.
