This paper investigates patterns in the demand for barge transportation along the inland waterway system. Non-parametric techniques including both rolling regression and locally weighted regressions are used to visually analyze the pattern of elasticity estimates along the river at the pool level. The results of these non-parametric approaches visually indicate that barge demand elasticity may ...

Today, a new infrastructure provisioning approach called Cloud Elasticity is evolving, covering three dimensions of elasticity: resource, cost, and quality. Recently, Cloud Elasticity has been utilized for Business Process Enactment in the Cloud as the involved services face highly volatile demand levels. Through treating the three dimensions equally, so-called Elastic (Business) Processes can ...

It is well known that the origin-destination (O-D) flow table of a subnetwork is not only determined by trip generation and distribution, but also by traffic routing and diversion, due to the existence of internal-external, external-internal and externalexternal flows. This result indicates the variable nature of subnetwork O-D flows. This paper discusses an elastic O-D flow table estimation pr...

Tolls are used to influence users to "voluntarily" choose paths in the system which optimize flows (VSO) to minimize social costs. When the toll solutions are not unique, administrators gain the flexibility to vary tolls in order to meet other goals while still maintaining optimal flows. For Fixed-Demand networks, it was known that path-tolls can be adjusted. However, the link-toll solution was...

This paper considers the role of promotional expenditures by firms in a differentiated product oligopoly model. Advertising is informative and has two types of effects on demand, accommodating effects, which increase total demand in the product class, and predatory effects, which serve only to redistribute consumers among brands in the product class. Depending on the relative importance of each...

This paper extends the notion of toll pricing and the toll pricing framework previously developed for fixed demand traffic assignment [4, 13] to the problem with elastic demand. The system problem maximizes net benefit to the network users [9, 20] and the user problem is the usual one of finding equilibrium with elastic demand. We define and characterize T , the set of all tolls for the user pr...

Residential demand for electricity is estimated for China using a unique household level dataset. Household electricity demand is specified as a function of local electricity price, household income, and a number of social-economic variables at household level. We find that the residential demand for electricity responds rather sensitively to its own price in China, which implies that there is ...

This paper studies a supply chain coordinated by a revenue-sharing contract in fuzzy environment. Two kinds of fuzzy programming models are discussed: revenue-sharing contract with fuzzy linear demand model and fuzzy iso-price-elastic demand model. Supply chain coordination in both centralized decision setting and centralized decision setting are achieved by obtaining the optimal solutions in t...
