Lifecycle architectures for rental fleets couple pricing, vehicle assignment, maintenance scheduling and disposal timing, and the profit they add over revenue-based scoring has two sources that behave differently. Mileage steering changes the odometer reading at which a vehicle reaches disposal, and decision-focused forecast training reduces ranking regret at that point. Both sources matter only where the cost-optimal disposal mileage lies within a band around an odometer mark at which wholesale prices drop. The band half-width equals the residual-value forecast error divided by the slope of the retention margin. On realized retirements of midsize sedans at one enterprise rental operator, 28.2% of vehicles fall inside the band. Coupling adds $206 to $228 per vehicle there and $7 to $13 elsewhere, differences indistinguishable from zero. Mileage steering supplies 60.7% of the premium and survives a step-aware forecaster; the decision-focused component falls from $67.60 to $8.20 once the forecaster learns the price drops. Richer telematics raise profit by $86 to $118 per vehicle in every cell, so architecture and data are separable contributions. Operators can restrict the cost of coupling to vehicles inside the band.

The purpose of the study was to examine solid waste disposal situation and its resultant effects in Winneba The research adopted quantitative approach for the study. The design for this research was a descriptive survey. The population for the study were residents of Winneba Township the capital of the Effutu municipality. The area is a fast growing urban community. Stratified sample sampling technique was used to select the respondents for the study. One hundred and fifty-six (156) residents were selected using strata sampling to answer questionnaires. The data entry and analysis was done by using the SPSS software package. The data was edited, coded and analysed into frequencies, percentages with interpretations. The study revealed that there was irregular or lack of routine collection of waste by WMD of EMA and ZoomLion Ghana Ltd. The study also indicated that, the landfill did not meet the requirement of a sanitary landfill as in the case of EMA and therefore could be described as an open dump. It is recommended that, adequate dustbins and skips should be provided by ZoomLion Ghana Ltd. in collaboration with the WMD and Municipal Assembly for residents in the Municipality for waste storage. It is recommended that the landfill site should be properly managed to avoid heaping of waste and burning.
