The 1995 survey on decision analysis (DA) in energy and environmental modeling by [Huang et al. Decision analysis in energy and environmental modeling. Energy 1995; 20: 843–855] lists 95 publications. We updated the survey and found that the number of publications has almost tripled to 252. We...

We present the results of a study on the effects of maintenance on the fuel efficiencies of a fleet of public buses. We classified maintenance into major, minor, and ineffective based on their expected levels of impact on fuel consumption. The results show a significant improvement in fuel...

We analyze trends in commercial energy consumption, changes in the fuel-mix, and the relation between energy consumption and economic growth in the ASEAN region from 1960 to 1986. The structure of energy demand is examined at the sectoral level to identify systematic variations over time and...

We present the results of a statistical study on the effects of the following four operational changes on the fuel consumption of scheduled buses: a change in the brand of engine oil used, a switch from crossply to radial tires, engine overhaul, and vehicle maintenance. This is an empirical...

We present the results of a factorization analysis of automobile fuel consumption in actual traffic. Three specific studies related, respectively, to trip purpose, road type, and time period of trip generation were carried out. In each study, the variations in vehicle fuel consumption were...

Index decomposition methodology was a technique first used in the late 1970s to study the impact of changes in product mix on industrial energy demand. A survey in 1995 listed a total of 51 studies. Since then, many new studies and several new decomposition methods have been reported and the...

We present a stochastic model for evaluating distributed generation investment under uncertainty. The objective is to estimate the break-even price and its probability distribution. The model is developed based on the probabilistic influence diagram technique and the main uncertain variables are...

We present the results of a statistical analysis on the fuel-consumption characteristics of 115 automobiles. The factors considered are vehicle weight, engine size, cumulative mileage, vehicle age, vehicle maintenance, make of vehicle, fuel brand, travel speed, trip length, travel time per trip,...

We have studied the fuel-consumption characteristics of 387 buses under actual operating conditions over a 12-month period. We have examined the variations in monthly fuel efficiency among service routes, bus models, and months of the year, as well as the effects of engine overhaul, weather...

Several recent studies have dealt with the methodology of decomposing the change in industrial energy consumption between two years into three separate components. Each component is associated with one of the following three effects: changes in production level, product-mix, and sectoral energy...
