In recent years, the value-added created in the transportation industry is about 8 percent of GDP of Iran. Due to the high-induced effect of transportation sector on the whole economy, analyzing transportation production function and its determinant is of great value for policymakers. The objective of the present research is to estimate the transportation production for the case of Iran and to ...

this study was conducted to determine the effects of increasing lighting after peak production on eggs production and hatchable eggs in broiler breeder hubbard f15. in this research we used from 4 growing saloons, that in per saloons were 5250 hubbards broiler breeder hens. in this experiment we used by line design way of glm for analysed data, that we considered the effects of two parameters, ...

in the fundamental production inventory model, in order to solve the economic production quantity (epq) we always fix both the demand quantity and the production quantity per day. but, in the real situation, both of them probably will have little disturbances every day. therefore, we should fuzzify both of them to solve the economic production quantity (q*) per cycle. using α-cut for defuzzific...

achieving optimal production cycle time for improving manufacturing processes is one of the common problems in production planning. during recent years, different approaches have been developed for solving this problem, but most of them assume that mean quality characteristic is constant over production run length and sets it on customer’s target value. however, the process mean may drift from ...

The purpose of this study is to evaluate the progress and regional variations of crop production in Bangladesh. The secondary data were used and collected for the years 1980-81 to 2002-03 from the ‘Statistical Yearbooks of Bangladesh’, ‘Yearbook of Agricultural Statistics’ and population census of different years. The study was conducted during the period from September 2006 to February 2008. A...

This communication addresses the integration of the supplier capacity in the procurement planning process of a customer within a supply chain. Since this supply chain evolves within an uncertain environment, uncertainties may be due to an ill-known demand (prevision) and to the customer production system (scraps, imprecise processing time...). Thus, we propose a collaborative process where the ...

SAGE.2 is a production system that improves its search strategies with practice. The program incorporates four different heuristics for assigning credit and blame, and employs a discrimination process to direct its search through the space of move-proposing rules. The system has shown its generality by learning search heuristics in five different task domains. In addition to improving its searc...

A Gram-positive bacterium, Brevibacillus sp. strain BAB-2500, was isolated as a lab contaminant in Gandhinagar, Gujarat, India. The draft genome (5.3 Mb) of the strain possesses genes for the reduction of arsenate and aluminum. These findings might provide insights into the utilization of this strain for improving crop production.

It is also available cut up into separate chapters for ease of downloading at: Because it lacks a Table of Contents, I have written one myself (see summary below and separate file). There is to be an email discussion group on the PRR, and the purpose of my comments is to assist people who might be interested in either reading the report and/or contributing to the discussion group. The Bank says...
