This paper presents a Cuckoo Optimization Algorithm (COA) model for the cost optimization of the one-way and two-way reinforced concrete (RC) slabs according to ACI code. The objective function is the total cost of the slabs including the cost of the concrete and that of the reinforcing steel. In this paper, One-way and two-way slabs with various end conditions are formulated as ACI code. The t...
A multi-stage stochastic programming for condition-based maintenance with proportional hazards model
Condition-Based Maintenance (CBM) optimization using Proportional Hazards Model (PHM) is a kind of maintenance optimization problem in which inspections of a system relevant to its failure rate depending on the age and value of covariates are performed in time intervals. The general approach for constructing a CBM based on PHM for a system is to minimize a long run average cost per unit of time...
the most costly operation in the oil exploration is the well network drilling. one of the most effectiveways to reduce the cost of drilling networks is decreasing the number of the required wells byselecting the optimum situation of the rig placement. in this paper, balas algorithm is used as a modelfor optimizing the cost function in oil well network, where the vertical and directional drillin...
selecting an appropriate manufacturing machine is a very important and complex problem for firms, which usually have to deal with both qualitative and quantitative criteria. taking into account the differences among machines in terms of cost, speed, quality and after sale services, type and number of machines are important parameters to consider. therefore, the goal of this paper is to propose ...
A generalized communication cost model is presented. The-model incorporates parameters that reeect empirical performance studies of various communication operations. This uniied framework allows quantitative comparison of diierent network architectures, as well as diierent communication algorithms executed on the same network architecture. Moreover, the model is general enough to accommodate bo...
Undesirable Output such as pollution and waste may occasionally occur in the production process, which should be reduced to improve efficiency. In the present study, cost efficiency model is presented in the presence of undesirable output by Inverse Linear Programming, and the desirable cost is calculated in order to achieve cost efficiency for units that are technically efficient but not cost-...
Background: Pre-hospital care plays an important role in managing patients who require emergency services and preserving human life. The aim of this study was to evaluate the cost of completed public pre-hospital emergency missions according to the activity-based costing model and to compare it with the cost of private pre-hospital emergency services in Mashhad in 2016. Methods: In this applie...
Data Envelopment Analysis (DEA) is a nonparametric tool for discriminating the best performers from a number of homogenous Decision Making Units (DMU). Cost oriented DEA models identify those best DMUs which run cost efficient process. This paper validates the outcome derived from the Ideal Frontier (mentioned in Sarkar. S (2014)) derived from non-central Principal Component Analysis and a slac...
Objective: For improving the quality of reproductive health services and providing appropriate health care to mothers to reduce their mortality and morbidity, it requires to apply the effective cost models used in the world. In this regard, the aim of the current study is to critically review the related literature on cost management of healthy reproductive services with the continuous midwifer...
