It is an important problem to analyze the collection costs and determine tenuring collection times to meet the pause time goal for a generational garbage collector. From such viewpoints, this paper analyzes the costs suffered for collections according to the working schemes firstly, and then, proposes one garbage collection model. Garbage collections occur at a nonhomogeneous Poisson process, a...

Given a model with multiple input parameters, and multiple possible sources for collecting data for those parameters, a data collection strategy is a way of deciding from which sources to sample data, in order to reduce the variance on the output of the model. Cain and Van Moorsel have previously formulated the problem of optimal data collection strategy, when each parameter can be associated w...

Uncontrolled growth of the urban population in developing countries in recent years has made solid waste management an important issue. Very often, a substantial amount of total expenditures is spent on the collection of solid waste by city authorities. Optimization of the routing system for collection and transport of solid waste thus constitutes an important component of an effective solid wa...

The collection and treatment of waste poses a major challenge to modern urban planning, particularly to smart cities. To cope with this problem, a cost-effective alternative to conventional methods is the use of Automated Vacuum Waste Collection (AVWC) systems, using air suction on a closed network of underground pipes to transport waste from the drop off points scattered throughout the city to...

calculating total cast of bank resources procurement methods which include current -free loan deposit, saving interest-free loan deposit, regular and net short-term investment deposit, long-term investment deposit and surety bond cash deposit and presenting their optimal integration require precise scientific studies. hence, this study is an attempt to know which methods are the best optimal in...

Cost optimization will be essential to the economic viability of future many-robot systems. Unfortunately, cost-optimal design will often depend sensitively on the performance and costs of candidate sensor and other components, and on both explicit mission-specific and implicit common sense application requirements. The development of a standardized integration architecture providing multi-leve...

Several papers have been presented in the last years regarding the design of reliable sensor networks. In all these papers, the system reliability was maximized, constrained by a fixed number of sensors. In these models, the cost has played an indirect unclear role. A minimum cost model for the design of reliable sensor networks is presented in this paper. The connections with previous models a...

We consider a production-inventory system that consists of an input-generating installation, a production unit and L intermediate buffers. It is assumed that the installation transfers the raw material j ∈ {1, . . . , L} to buffer Bj, and the production unit pulls the rawmaterial j ∈ {1, ..., L} from buffer Bj. We consider the problem of the optimal preventive maintenance of the installation if...
