abstract quantitative analysis of production through evaluating the level of factor usage is a major part in agricultural management, which aims at increasing production by optimum usage of resources. this study has estimated and analyzed stochastic frontier production function and calculated technical efficiency of semi-mechanized broiler farms located in gorgan district. the survey data were ...

This study is the first in-depth empirical analysis of design process and outcome of socalled “toolkits for user innovation and design”, a very recent method for integrating customers in new product development and product design. Evidence from four experiments conducted in the watch market shows that user-designers engage in learning-by-doing behavior and yield highly heterogeneous new product...

The database system EKIDES (Ergonomics Knowledge and Intelligent Design System) assists designers of technical systems, equipment, products and workplaces to meet ergonomic requirements for all system components and their interactions during the planning, development and subsequent design and blueprint processes. EKIDES is a design tool in form of an electronic reference system and an evaluatio...

Although constructs have been developed for designing the features of Behavior Change Support Systems (BCSSs), detailed descriptions and guidelines for their software level implementation are lacking. Through developing software design patterns one is able to examine BCSSs at a more intricate technical level instead of merely a black-box approach to them. In this paper, we present a software de...

In the mining industry, at the beginning of development of a project, a consultant is assigned to build a design feasibility study to incorporate the client requirement, government regulation, and other inputs into the design. The consultant usually faces overwhelmed stages due to changes caused by the client and other stakeholders and has to repeat the process of inputting requirements into th...
