Introduction: Access to credits to cover the costs needed to buy production inputs at the optimal level is necessary, and budget restrictions can be an effective factor in not using the optimal economic level of production inputs. Due to the importance of the poultry industry in providing a major part of the food and protein needs of the country, the aim of this study is to investigate the effect of budget restrictions on the production of meat poultry farms in Masjid Soleyman city. Materials and Methods: In this study, the indirect production function approach was used and the required information was collected by completing 43 questionnaires at the city level in 2018. Findings: The results of the study showed that 62% of poultry units had budget restrictions of 26.62%, which caused a decrease in chicken meat production by 32.12% in this city. The return to scale was equal to 1.30, which indicates an increasing return to scale for the studied units. Conclusion: Removing the budget limit of poultry farming units can be considered an effective step towards increasing production and productivity. In this regard, it is recommended that the price policies of inputs and products, as well as the import of inputs, should be given special attention in order to reduce the problems related to the budget limitations of broiler chicken production units. For example, by determining the appropriate import tariff and subsidizing the import of these inputs, the inputs can be provided to poultry farmers cheaper. [ABSTRACT FROM AUTHOR]

Project planning and scheduling are one of the most important issues in construction engineering and management. It is being crucial to progress developed countries. One of the major challenges in construction project management is time and cost management. The traditional view lonely is not able to meet the needs of this field. Therefore, the use of modern management approaches can be greatly helpful. Time and cost are among the important objectives of each project. Cost and time trade-off is among the major important issues in projects planning and control and the main of solving this problem is actually analysis of interaction of different types of project costs and time of the project. In this paper, a time and cost trade off project scheduling problem under budget constraint is studied. For this purpose, a meta-heuristic genetic algorithm is developed to find the optimal solution in MATLAB. Completion time sensitivity analysis is done according to different budget level. In order to validate proposed algorithm, problem is solved by GAMS and the outputs between them are compared. The results show that proposed meta heuristic algorithm is able to solve problem optimally so that differences between samples solution were zero in different budget level.
