over the years we have witnessed the growing importance of supply chain operations and supply chain management (scm), as supply chains play a major role in every step of the product life cycle. therefore, this paper will dea-based performance evaluation approaches for overall supply chain can be categorized. future perspectives and challenges are discussed
the proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(x/h)0.5 for low-rise and mid-rise buildings, 2- sin(πx/h) for high-rise buildings. these two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. the assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...
in this paper, a discrete event simulation model of iranian railway system is used for analyzing performance of the system in freight sector. the model analysis shows more sensitivity of the system on loading and unloading facilities than on number of wagons and locomotives. system optimization through simulation optimization technique, shows that more than 4% of all wagons available in the net...
We study the effects of different pricing strategies available to a production–inventory system with capacitated supply, which operates in a fluctuating demand environment. The demand depends on the environment and on the offered price. For such systems, three plausible pricing strategies are investigated: static pricing, for which only one price is used at all times, environment-dependent pric...
this paper attempts to examine the physical and financial performance of some primary dairy co-operatives in west bengal state in indian context. the study suggests that financial performance indicators dominate over physical ones, and all the dominating variables have long term positive impact on primary milk producers’ co-operative societies (pmpcss). also, the significant impact of financial...
studying the effect of marketing tactical capabilities on the financial performance of the firms is now proposed as one of the most important priorities of marketing researches. however, the results of the studies in many academic fields that are conducted about a specific issue are usually contrasting. meta-analysis is a research approach that helps the researcher to achieve a suitable combina...
patients and methods subjects of this study include teaching hospitals in mashhad, affiliated with mashhad university of medical sciences and the tool used in gathering the data was a questionnaire, completed based on the information provided by the proceedings of the meetings held by the ethics committees. also, for the purpose of gathering the suggestions, specifically on the improvement of t...
We propose a new method of discriminant analysis, called High Dimensional Discriminant Analysis (HHDA). Our approach is based on the assumption that high dimensional data live in different subspaces with low dimensionality. Thus, HDDA reduces the dimension for each class independently and regularizes class conditional covariance matrices in order to adapt the Gaussian framework to high dimensio...
Recently, short fiber reinforced composites are widely utilized in many structural parts in automobile, infrastructure and electric equipment applications due to their high specific strength, high specific stiffness, long fatigue life and high impact resistance as well as cost effective capability of production. If these parts are exposed to low-velocity impact, significant damages may develop ...
Recently, underwater wireless sensor network is one of the popular research topics to scientist. There are many novel methodologies to reach the goal of the effectiveness network performance such as cluster-based structure, in-network data aggregation, etc. In this paper, we assume the network is clustered by a specific clustering scheme. Then, we suggest a new geographicaldata-aggregation meth...
