基于模糊多属性决策方法的承发包模式比较研究

在前人对工程承发包模式研究成果的基础上，从项目成本、效益以及风险的角度建立了比较指标体系，并提出了指标赋值方法。将承发包模式的选择问题归结为多属性决策中（MADM）的排序问题，采用离差最大化准则下的多属性决策的最优组合赋权方法来对各指标的权重进行赋值，并采用TOPSIS方法来对各方案进行比较研究。，最后通过算例进行计算和分析。

Risk and reward in public transportation contracting

The workshop discusses and documents a number of countries’ experiences regarding risk and reward in the delivery of public transport and determines the way in which competitive pressures actually work (or not) to deliver efficient and effective services. Papers are grouped into three main themes, i.e., public versus private management; negotiated versus competitively tendered contracts; and measures to improve performance. This chapter begins with a brief overview of each of the eight papers. This is followed by a section that out the discussions that emanated from the papers. Finally, the main policy and research recommendations are presented.

Imperfect reversibility of air transport demand: Effects of air fare,fuel prices and price transmission

There are recent evidence that air transport demand may not have a perfectly reversible relationship with income and jet fuel prices, as is assumed in most demand models. However, it is not known if the imperfectly reversible effects of jet fuel price are a result of asymmetries in the supply side, i.e., asymmetries in cost pass through from fuel prices to air fare, or of demand side behavioral asymmetries whereby people value gains and losses differently. This paper uses US time series data and decomposes air fare and fuel price into three component series to develop an econometric model of air transport demand that is capable of capturing the potential imperfectly reversible relationships and test for the presence or absence of reversibility. We find that air transport demand shows asymmetry with respect to air fare, indicating potential imperfect reversibility in consumer behavior. We also find evidence of asymmetry and hysteresis in cost pass-through from jet fuel prices to air fare, showing rapid increases in airfare when fuel prices increases but a slower response in the opposite direction.     

Path-differentiated pricing in congestion mitigation

Instead of charging tolls on individual links, this paper considers doing the same on paths. Path and link tolls are “valid” if they encourage motorists to use routes that collectively lead to a target distribution, e.g., one that minimizes travel delay. Because the numbers of valid link and path tolls are typically infinite, an objective in pricing tolls is to find a set of valid tolls that yields the least revenue to lessen the financial burden on motorists.Path tolls are generally more flexible than link tolls and this paper shows that this flexibility can substantially reduce the financial burden on motorists. Additionally, valid path tolls yielding the least revenue possess characteristics with interesting policy implications. To determine these path tolls, it is natural to formulate the problem as a mathematical program with complementarity constraints. However, this paper also investigates alternative formulations that highlight the problem’s complexity and suggest ways to solve the problem efficiently.
