To calculate partial and total productivity of production factors in broiler farms in Yazd province, 72 manufacturing units were selected based on simple random sampling method and their information and statistics were collected for one production period in the second half of 2013. To measure productivity, the Cobb-Douglas production function was estimated using classic and fuzzy regression met...

A highly productive team throughout an agile software development process is very instrumental in achieving project success. This research presents a system dynamics (SD) based approach to model agile software development teamwork productivity by analyzing productivity influence factors. Identification of main factors influencing productivity and how they impact agile teamwork are carried out t...

planning for productivity factors of engineering resources is the main concern that should be addressed in the training and engineering management in different organizations. productivity of engineering resources, which eventually results in the organizational productivity, may be viewed from different perspectives. one of the best approaches is to study the engineering resources productivity w...

Systems developers and researchers have long been interested in the factors that affect software development productivity. Identification of factors as either aiding or hindering productivity enables management to take steps to encourage the positive influences and to eliminate the negative ones. This research has explored the possibility of developing an estimable model of software development...

supply chain management is one of modern approach in the field of operation and production management. nowadays success and survival of manufacturing organizations depend on effectiveness and productivity of supply chains. this research tries to investigate contributing factor to enhance supply chain productivity. then by using fuzzy promethe-a multiple attribute decision making (madm) - tous a...

Managing software development productivity is a key issue in software organizations. Business demands for shorter time-to-market while maintaining high product quality force software organizations to look for new strategies to increase development productivity. Traditional, simple delivery rates employed to control hardware production processes have turned out not to work when simply transferre...

Increased productivity has been cited as one of the benefits of scientific collaboration. While some studies have identified a positive relationship between collaboration and publication productivity, others have found a negative or no clear relationship between the two. A number of factors determine the relationship established, ranging from the context under which research is carried out that...

abstract-due to the important role productivity plays in future decision making and programming, the productivity indexes should have accurate quantities. in this study, auto-regressive distributed lag (ardl) and genetic algorithm (ga) methods are applied to time series of 1978-2008 to accurately measure total factor productivity (tfp) in the agricultural sector of iran. the comparison of these...

in despite of all progress in technology in mining industry, still labor is one of the key factors in mining operation. this paper presents a system dynamics approach to evaluate the mining labor productivity. therefore, after the identification of main effective variables, two quantitative and qualitative models were built. the qualitative model illustrates the complex interrelated structure o...
