A Software Cost Model with Reliability Constraint under Two Operational Scenarios
نویسندگان
چکیده
In this paper we extend the reliability constrained cost minimization (RCCM) model by Helander et al. (1998) from two view points: time non-homogeneous property on software failure-occurrence process and gap between testing and operational phases of software product. The expected cost minimization with reliability constraint is formulated as a non-linear minimization problem under alternative scenario on the operation. We develop an effective optimization algorithm based on the Kuhn-Tucker conditions and provide an illustrative example on how to design a component-based software.

Design of a Reliable Facility Location Model for Health Service Networks
This paper proposes a novel facility location model for health service network design by considering different key elements including the reliability aspects, service capacity, congestion, service quality, surrounding public infrastructures, geographical accessibility and several types of cost such as investment, transportation and operational costs. We formulate the problem as a robust scenari...
متن کاملStochastic Unit Commitment in the Presence of Demand Response Program under Uncertainties
In this paper, impacts of various uncertainties such as random outages of generating units and transmission lines, forecasting errors of load demand and wind power, in the presence of Demand response (DR) programs on power generation scheduling are studied. The problem is modelled in the form of a two-stage stochastic unit commitment (UC) which by solving it, the optimal solutions of UC as well...
متن کاملA Node-based Mathematical Model towards the Location Routing Problem with Intermediate Replenishment Facilities under Capacity Constraint
In this paper, we study the location routing problem with replenishment facilities (LRPRF), an extension of the location routing problem (LRP) where the vehicles can replenish at some replenishment facilities. Vehicles leave the depot with load on-board, serve customers until out of load, and then either return to a replenishment facility to reload or return to the depot, completing their route...
متن کاملElectrical Substation Efficient Maintenance Policies Based On Semi-Markov Modeling and Approximate Inverse Preconditioning
Maintenance is one of the most critical tasks during the operation of a system. The reason is profound as it has effect on the life extension of its components and provides also a better delivered quality of service. Thus a maintenance policy may increase the reliability, the availability and other performance indicators which are mainly used to measure maintenance efficiency, but it also incre...
متن کاملCentralized Path Planning for Multi-aircraft in the Presence of Static and Moving Obstacles
This article proposes a new approach for centralized path planning of multiple aircraft in presence of the obstacle-laden environment under low flying rules. The problem considers as a unified nonlinear constraint optimization problem. The minimum time and control investigate as the cost functions and the maximum velocity and power consider as the constraints. The pseudospectral method applies ...
